Chapter 1 - Introduction & Background City of Mendota Heights 2040 Comprehensive Plan Update 1 1 INTRODUCTION & BACKGROUND The City of Mendota Heights has a long history of commitment to planning, resulting in unique residential living environments and business centers. The city’s first Comprehensive Plan was adopted in 1960, some years before the Metropolitan Land Planning Act went into effect, requiring communities to incorporate regional policies and guidelines into their plans. The city has used its Comprehensive Plan to guide decisions since the 1960’s; and the community looks much like it was envisioned in 1960 which emphasized high quality residential neighborhoods, open space and parks, and well-planned commercial and industrial areas. The community is essentially developed and is enjoying the fruits of its long-range vision and development policies. Infill properties will continue to be built out, following the community’s development philosophy. Redevelopment is also happening in targeted areas, following the city’s commitment to provide a high quality of life for its residents and businesses. The city understands its role as part of the greater Metropolitan Region and will continue to plan accordingly, which is further described in Chapter 2. Land Use & Growth. The city has adopted the following Vision and Mission Statements to guide planning and development: Vision Statement Mendota Heights will be recognized as a high quality, family- oriented residential community, with a spacious, natural feel and the amenities of a city. Mission Statement Our mission is to preserve and enhance the quality of life in Mendota Heights by providing quality public safety, infrastructure, and planning for orderly and sustainable growth. Chapter 1 - Introduction & Background City of Mendota Heights 2040 Comprehensive Plan Update 2 Plan Organization This 2040 Comprehensive Plan (“Plan”) is organized in chapters similar to the previous 2030 Comprehensive Plan, but with new chapters on Economic Development and Resilience. This Plan is organized as follows: 1.Introduction & Background 2.Land Use & Growth 3.Transportation 4.Parks & Open Space 5. Housing 6. Economic Development 7. Natural Resources 8. Resilience 9. Mississippi River Critical Corridor Area 10.Water Supply & Sanitary System 11.Implementation 12.Appendix Each chapter identifies a set of goals and policies associated with the topic. Appendix items are provided, including a Public Engagement Schedule Summary and the Surface Water Management Plan (July 2018). Setting Mendota Heights is located in northern Dakota County, bordering the Minnesota and Mississippi Rivers. The City of Lilydale and the City of Mendota border the city on its northwest side. Across the rivers are the cities of St. Paul and Minneapolis, Fort Snelling and the Minneapolis-St. Paul International Airport (MSP). The east is bordered by Delaware Avenue and the cities of West St. Paul and Sunfish Lake. Interstate 494 divides Mendota Heights from Eagan to the south. Interstate I-35E divides the city north to south.

The river bluffs, rolling topography, and wooded areas have provided an excellent setting for residential development. The topography has brought about the creation of a curvilinear local street system and allowed for intimate residential neighborhoods to be nestled amongst mature wooded settings, lakes, wetlands, nature preserves, and the Mississippi and Minnesota River bluffs. Mendota Heights is a premier suburb, offering high-quality residential and business areas. Per capita income and property values are among the highest in the area, but homes in more moderate price brackets are also available. The residents of Mendota Heights enjoy proximity to an extensive system of regional and local parks, and convenient access to the regional highway system, international airport, and metropolitan employment centers. These factors have helped make Mendota Heights an attractive place to live. Centrally located in the metropolitan area, the Minnesota and Mississippi Rivers form a natural green belt around it, allowing the community to maintain a quiet, private way of life, unique in the Twin Cities. Mendota Heights achieved its exceptional residential neighborhoods and successful business community by following the comprehensive plans set forth some decades ago. Innovative and forward thinking on the part of community officials has resulted in a planned community, which affords a high-quality lifestyle for its residents while providing a full Chapter 1 - Introduction & Background City of Mendota Heights 2040 Comprehensive Plan Update 4 array of services and employment opportunities. The community has preserved an abundance of parks and open spaces, encourages spacious residential development, and has planned for diversified, high technology offices and business areas. Excellent schools and a well-educated populace complement the traditional character of the city. Civic pride and aesthetic excellence are high priorities in Mendota Heights. The community set out early in its incorporated history to create attractive residential neighborhoods by planning for aggressive protection and wise use of its available environmental assets. The rich abundance of woods, wetlands, and open space areas that provide the natural feel of the community today, are a testament to the proactive planning of Mendota Heights’ forefathers. As the Twin Cities metropolitan area has grown up around it, Mendota Heights has actively pursued its objective of preserving open spaces, making this community one of the region’s most attractive places to live. The environment has played a central role in the city’s land use planning. Public Engagement Process The process of updating the Plan for Mendota Heights was initiated in late 2016 when Stantec, the city’s planning consultant, began updating background information and demographics for the Plan. Stantec also worked with Tangible Consulting, preparing a report analyzing the market and development content of the city. A background report was shared with the Planning Commission in early 2017. The city held three public information meetings at the local schools; and provided a “hands-on” display at the city’s annual Fire Station Open House in 2017. In a series of meetings later that year, the Planning Commission reviewed and adopted the draft Vision, Mission, and Goals & Policies for the Plan. This material was shared with the Parks Commission and with the larger community in four community open house meetings in the fall of 2017. There was also an online survey and an invitation for comments on the city website and Facebook page.

The Public Engagement Schedule Summary is attached as Appendix C. The comments have been grouped into eight topics as illustrated below in the blue boxes: Character, Environment, etc. These topics relate strongly to the Key Planning Issues identified on the following page, as indicated by the arrows connecting similar ideas. Taken together, these issues and topics represent the ideas that will be the guiding force shaping the Comprehensive Plan Update. These issues are reflected in the Goals and Policies in the Plan as well. TopicsKey Planning Issues Chapter 1 - Introduction & Background City of Mendota Heights 2040 Comprehensive Plan Update 6 Key Planning Issues The initial discussion with the Planning Commission, grounded in the background information and analysis, was condensed into seven key planning issues: 1. Character, Natural Feel, Design Mendota Heights is open, spacious, green, and natural. The environment and green space is essential to the city’s character, and the character and design of our community is important to maintain our quality of life. 2. Commercial/Retail Options Many people wish there were more restaurant and shopping options in Mendota Heights. 3. Development & Redevelopment Sites The city is almost fully developed, but there are a few sites where new development or redevelopment can occur and there is keen interest in how to maximize their potential. 4. Housing Mendota Heights is mostly high-end and mid-range valued single-family homes today. But the city recognizes the need for a range of housing choices including, but not limited to, 1) life-cycle opportunities for people of all generations and stages of life, and 2) workforce housing to support people working in a wide range of careers. 5. Minnesota Vikings Facility The Vikings football team has built its new headquarters and practice facilities nearby in Eagan, within a 200-acre mixed use development featuring offices, retail, and housing. Mendota Heights residents are concerned about traffic impacting the city. This mix of uses is anticipated to be developed. On the business side, the Vikings development could be competition for Mendota Heights businesses or could be an opportunity for businesses to capitalize on new activities. 6. Airport The MSP Airport is conveniently located nearby across the river, but also poses a nuisance with aircraft noise. 7. Infrastructure Like many communities, Mendota Heights’ roads, bridges and other infrastructure are aging and in need of maintenance. The city must plan in conjunction with county and state agencies in order to preserve quality of life and safety. Chapter 1 - Introduction & Background City of Mendota Heights 2040 Comprehensive Plan Update 7 Community History Mendota Heights has a long and rich heritage, which serves as a source of identity for the community. Mendota Heights is located near the confluence of the Mississippi and Minnesota Rivers. The Dakota people knew and referred to this place as “Mdo’–te” or “the junction of one river with another.” French explorers and traders who settled the area in the late 1600’s named the Minnesota River “Sans Pierres” because the river was silty, with few rocks. British explores and traders who arrived a few years later misunderstood the French name, calling the river Saint Peter’s. Native Americans view the area as an important meeting place. The current Pilot Knob site (now city-owned property) overlooks the confluence of the Mississippi and Minnesota Rivers. It is considered sacred by the Dakota who called it Oȟéyawahe, or “the hill much visited.” Pilot Knob was named by riverboat pilots as the landmark overlooking Fort Snelling, the first American fort in Minnesota. Fort Snelling was constructed in the 1820s; and the name of the area was later changed to Mendota, which in Dakota means, “meeting of the waters.” In 1852, the territorial legislature changed the name of the river to Minnesota, a version of its Dakota name. Fur traders established a trading post in the early 1830’s within what is now Mendota Heights. The trading post, coupled with Fort Snelling located across the river, formed Pilots Knob. Mouth of the Saint Peters River, 1846-1848, Seth Eastman, Source: Minnesota Historical Society Chapter 1 - Introduction & Background City of Mendota Heights 2040 Comprehensive Plan Update 8 the basis for one of the first settlement areas in Minnesota. During the period from 1837 to 1858, the Dakota ceded large tracts of land to the United States, which was then deeded to settlers who tilled the land and operated dairy farms. Gradually, individual homes began to appear along the St. Paul border in the north and on the hills above Mendota Township in the west. Between them were farms, country schools, and estates. The population of Mendota Township in 1860 was 454. The area grew slowly to 1,360 at the start of World War II. St. Peter’s Church was originally built in 1840; re-built in 1853 atop the bluff overlooking the rivers; and today is the oldest church in continuous use within Minnesota. Several trails crossed the area, including the Mission Trail. It connected the river to the Dakota Village at Kaposia, located in present-day South St. Paul. Dodd Road, the first military road through the region, was completed in 1849 and connected the community to St. Peter. Dodd Road currently bisects the city and continues to provide a north-south travel artery throughout the community. The Old Mendota Road, which is now Highway 62 (formerly Highway 110), provided for east-west travel through the area. The Minnesota Central, the first Dakota County railroad, later the Chicago, Milwaukee & St. Paul, ran through Mendota Township, crossing the Minnesota River, and carried supplies to Fort Snelling. The Chicago, St. Paul, Minneapolis, and Omaha Railway was also an early railroad in the area. Following World War II, farmers began to sell lots for individual homes and acreage for residential subdivisions. Home construction increased rapidly, particularly in the northern section of the township and by 1950, the population totaled 2,107. The Township of Mendota was established in 1858, and was eventually divided into two separate towns; Mendota being chartered in 1887, and incorporated in 1936. The remainder of the township was incorporated as Mendota Heights in 1956. Omaha Railroad Depot in Mendota, ca. 1900. Source: Minnesota Historical Society Chapter 1 - Introduction & Background City of Mendota Heights 2040 Comprehensive Plan Update 9 Interstate 494 comprises the southern border of Mendota Heights. Its intersection with Interstate 35E acts as a primary “gateway” into the community, as does Highway 55 as it crosses the Mendota Bridge. Other gateways include the Interstate 35E/Mississippi River crossing and Highway 62, as it enters the community from the east. Minnesota Highway 13 traverses the west and northwest edge of the city near the Mississippi and Minnesota Rivers. Steep bluffs along those rivers include the natural open spaces of Fort Snelling State Park, Minnesota Valley National Wildlife Refuge, and Lilydale Regional Park. These together with the Dodge Nature Center provide a greenbelt that surrounds and cuts into Mendota Heights. The location of these features is illustrated on Map 1-1. Community Facilities & Features shown below. Map 1-1. Community Facilities & Features Chapter 1 - Introduction & Background City of Mendota Heights 2040 Comprehensive Plan Update 10 The natural and open space areas, when combined with the 770+ acres of community parks, three golf courses, Rogers, Augusta, and Lemay Lakes, and with the naturally rolling terrain and mature woodlands, create the appealing “natural open” setting of the city. These features and spaces are located adjacent to the major roadways and create a unique, natural setting for intimate neighborhoods. The views of the River Valleys from adjacent bluffs and bridge crossings are nothing less than spectacular. The predominance of scenic, natural vistas and corridors within a community located so close to the core of the Twin Cities is truly unique within the Metropolitan Region. This being the case, the City of Mendota Heights considers it paramount to protect and enhance the natural living environment for its residents. View of the River Valley Chapter 1 - Introduction & Background City of Mendota Heights 2040 Comprehensive Plan Update 11 Development History Early History The river topography and landscape of bluffs, ravines, views, lakes, and wooded areas have provided attractive settings for residential settlement. Mendota Heights was a part of Mendota Township until the Village of Mendota Heights was incorporated in 1956. 1957 to 1977 The first Land Use Plan for Mendota Heights was adopted in 1959, one of the first in the metro area. Its purpose was to guide public and private development to achieve balanced residential and commercial/industrial growth, in order to assure the availability of tax funds for schools and public services. At that time, 21% of the land (exclusive of golf courses and cemeteries) was developed. The city’s history of early land planning established a clear and well-defined pattern for future land uses. The 1959 Plan identified the following needs: •The need for additional east-west thoroughfares; •The need for community connections across future I-35E; •The designation of a business/ industrial area in the southwest corner of the city; •The desire to limit commercial “strip” development; and •The decision to continue the semi-rural character of the residential areas. Cherry Hill Development 1961, Source: Minnesota Historical Society Chapter 1 - Introduction & Background City of Mendota Heights 2040 Comprehensive Plan Update 12 Many of the major objectives of the 1959 Plan came to fruition as the Plan was largely followed over the ensuing years. In the twenty-year period from the late 1950’s to the late 1970’s, St. Thomas and Visitation schools were established (1955-56); Fort Snelling State Park was established (1961); the I-35 bridge into St. Paul was built (1965); Henry Sibley High School was built (1971); and in 1974, Mendota Heights became a city. Overall, an additional 40% of the land area was developed, most of it to establish new residential areas. 1977 to 1997 The land use pattern initially laid out by early comprehensive plans was clearly established along with several transportation improvements. Both I-35E and I-494 were built during this period. I-35E was extended in both directions, into downtown St. Paul and south into Burnsville. Interstate 494 was constructed along the southern border of the city and replaced Highway 110 (now Highway 62) as the primary east-west route. In this period, United Properties began the development of the Mendota Heights Commercial/ Industrial Business Park. Several areas designated as residential were developed throughout the city. The availability of the Interstate routes did relieve local roadways of some traffic, particularly in the cases of Highway 62 and Highway 149. The accessibility of the Interstate routes also more clearly established distinct neighborhoods in the community. The 1959 Land Use Plan emphasized the importance of east-west routes and planned crossings at Marie Avenue, Mendota Heights Road, and Wagon Wheel Trail, all of which were built more than 20 years later. Aircraft traffic noise from flights over Mendota Heights dramatically increased in this period as well, due to the growth and expansion of the airline industry and the Minneapolis-St. Paul Henry Sibley High School Visitation School Chapter 1 - Introduction & Background City of Mendota Heights 2040 Comprehensive Plan Update 13 International Airport. The increasing number of flights, larger aircraft, and expanded use of the runways over the Mississippi River corridor, continue to impact the land use and living environment of the southern part of the community. The Metropolitan Airports Commission (MAC) actually bought out one neighborhood and created a flight path corridor, near Acacia Cemetery, within Mendota Heights. Homes were removed and the area was re-developed for industrial uses. Other residential areas were part of the Part 150 Sound Insulation program, receiving funds to upgrade windows and insulation in existing homes. New residential neighborhoods have been built with additional sound insulation and modified building techniques. Total operations at the Minneapolis-St. Paul International Airport (MSP) increased from 230,793 in 1972 to 483,013 in 1998, more than doubling. This increase in flights, along with expansion of the flights over the new residential areas and outside of the flight corridor, has adversely affected many neighborhoods of the city. The city put forth considerable time and effort to reduce aircraft noise and operations over the city, establishing an Airport Relations Commission (ARC), participating in the Dakota County Airport Relations Commission (DCARC), and the Metropolitan Aircraft Sound Abatement Council (MASAC) and adopting Minnesota’s first Noise Attenuation Ordinance. MSP International Airport, located across the Minnesota River west of Mendota Heights, Source: USDA Aerial Photography Field Office Chapter 1 - Introduction & Background City of Mendota Heights 2040 Comprehensive Plan Update 14 1998 – 2007 From 1998 to 2006, the city issued 436 residential building permits; and of those, 259 were for single-family homes. In 2003, the city saw the most development during this period, with a total of 125 residential permits issued during that year. A number of significant projects reshaped Mendota Heights during this time. The most visible is the Village at Mendota Heights, a mixed-use development at the northeast intersection of Highway 62 and Dodd Road. The city acquired the property to create an urban town center that includes a senior residential facility, townhomes, condominiums, a boutique-like retail center, and an open space plaza. A second significant change is the Summit of Mendota Heights, a mixed residential development consisting of townhomes and a multi-story condominium. This development is located on the former site of the Ecolab research building at Sibley Memorial Highway and Wachtler Avenue. Another residential project is the Hidden Creek development, a residential plat of generally one-acre lots. Two other projects have showcased the city’s desire to preserve and retain existing open space. The Mendota Heights Par 3 Golf Course had operated as a privately-owned facility for many years, until the owners proposed to close the 17-acre facility and develop the property into approximately 30 single-family lots. After a successful referendum, the city purchased the golf course and is now operating the facility as a municipal course. Perhaps the most important project also involves the city’s decision to spend public dollars to preserve the Pilot Knob area, just off the Mendota Bridge between Acacia Cemetery and Highway 55. The city joined with other public entities, including Dakota County and the Minnesota Department of Natural Resources, and purchased a number of large parcels totaling 25.5 acres. The land will be retained as open space, and is currently being restored to its pre- development environment. The property has historical and cultural significance on many levels, The Village at Mendota Heights Chapter 1 - Introduction & Background City of Mendota Heights 2040 Comprehensive Plan Update 15 including as a sacred site for native people, a nearby gathering area for the 1862 transfer of the Minnesota Territory lands to the U.S. government, and the “Pilot Knob” landmark for steamboats approaching the confluence of the Minnesota and Mississippi Rivers. In 2017, Oȟéyawahe/Pilot Knob is listed on the National Register of Historic Places. 2008-2018 Since the last Comprehensive Plan was prepared, a number of significant developments have taken place in Mendota Heights. The economic recession from 2007 to 2012 impacted development cross the Twin Cities, including Mendota Heights and there was little development activity during those years, but coming out of the recession there was some significant activity. The Mendota Plaza Shopping Center at Highway 62 and Dodd Road saw a major renovation during this period, with a 15,000-square-foot Walgreen’s pharmacy added in 2012; White Pine Senior Living, a 50- unit assisted living and memory care facility completed in 2014; and the 18,000-square-foot Gemini Medical offices in 2017. Also at Mendota Plaza, a new 4-story 139-unit apartment project called The Reserves at Mendota Village was completed in 2018 by At Home Apartments. It is the first new market-rate project in Mendota Heights in thirty years. The project is proposed to include 11,000 square feet of commercial space in two buildings sharing the site with the apartments. A new market rate apartment project began development in 2018 by Michael Development on the site of the former Mendota Motel and Larson Garden Center at Highway 13 and Acacia Drive. Phase I provides 70-units of market rate apartments, with underground and surface parking. Phase II is providing between 64-68 units of senior (aged 55+) units of housing. Both phases were expected to be completed by late 2019 to mid-2020. The Vikings football team’s new headquarters and surrounding development in nearby Eagan has generated considerable discussion and will impact Mendota Heights with traffic, noise and light, but also with potential increases in economic activity and property values. Located just off the southeast edge of Mendota Heights, it will include the teams’ corporate offices, practice facilities, 6,500-seat stadium, athletic clinic, team Hall of Fame, and ancillary offices, hotels, The Reserves at Mendota Village Mendota Heights Apartments - 2160 & 2180 Hwy 13, Source: Kaas-Wilson Architects Viking’s Headquarters, Practice Facilities & Development Mendota Heights 2040 Comprehensive Plan June 2019 Introduction & Background 1-19 A new market rate apartment project began development in 2018 by Michael Development on the site of the former Mendota Motel and Larson Garden Center at Highway 13 and Acacia Drive.

While no major roadway projects have been built recently, one of the major highways in Mendota Heights has been renamed. In the summer of 2018, Highway 110 was renamed Highway 62, acknowledging it as an extension of Highway 62 that starts on the west side of the Mendota Bridge and extends west through Minneapolis and other suburbs to I-494 in Eden Prairie. Community Facilities / Services The City of Mendota Heights currently retains a full complement of administrative services, including Administration, Engineering, Planning, Public Works, Parks & Recreation, Police, Fire, Finance, and Code Enforcement.

A family householder is a householder living with one or more people related to him or her by birth, marriage, or adoption. The householder and all people in the household related to him or her are family members. A non-family householder is a householder living alone or with non-relatives only.

Chapter 1 - Introduction & Background City of Mendota Heights 2040 Comprehensive Plan Update 26 Age Distribution Figure 1-6 to the right depicts this aging trend in Mendota Heights. In just 14 years, the share of the population over and under 45 years of age has flipped – from just under half to just over half. Mendota Heights’ age trends follow the age composition trends of the Twin Cities Metro Area. The greatest population gains in the 1990s in the Seven-County Metro Area were in the forty-five (45) to fifty-four (54) year old age group, which is the same as Mendota Heights’ largest percentage category. This was a result of the Baby Boom generation moving into an age category previously occupied by the smaller Depression and World War II generation. The generation after the baby boom generation, also known as Generation X, 35-to-44-year-old age group, also grew significantly in the 1990s, just as in Mendota Heights. The continued aging of the population creates new challenges for the Seven-County Metro Area, as well as for the City of Mendota Heights. The demand for a wider range of services and housing choices, such as townhomes, one-level housing, assisted living, and so on, rather than traditional single-family homes. The Metropolitan Council has estimated that between 2000 and 2030, the population under the age of 55 is projected to increase by nineteen percent (19%) in the Twin Cities Seven County Metro Area, while the number of people 55 and over is expected to more than double, an increase of 111%. If the City of Mendota Heights continues to follow the population trends of the greater Metropolitan Area, the needs of the aging population will need to be recognized and addressed.

CITY OF MENDOTA HEIGHTS 2040 Comprehensive Plan Update Chapter 2: Land Use & Growth This page is intentionally blank. 1 Chapter 2 - Land Use & Growth City of Mendota Heights 2040 Comprehensive Plan Update 2 LAND USE & GROWTH Most of the developable land in Mendota Heights is completely developed and the city maintains its low-density and open feeling due to substantial areas of public and private open space, wetlands, lakes, bluff and wooded areas. The developed land use pattern is dominated by strong residential neighborhoods throughout the city; business and industrial developments in the southwest corner of the community; major institutional uses such as cemeteries, schools, and golf courses spread out intermittently; and protected natural areas such as Dodge Nature Center, and the bluffs and ravines along the Mississippi River corridor. The city’s natural resources, open spaces and recreation areas define the character of the community and are reflected in both the Existing Land Use and Future Land Use Plans contained in this chapter. Further details regarding the city’s plans to maintain and enhance these systems can be found in Chapter 4. Parks and Trails; Chapter 7. Natural Resources; and Chapter 9. Mississippi River Corridor Critical Area of this Plan. This chapter focuses on creating a sustainable balance between protecting the community’s high quality natural resource systems while enhancing and supporting the built environment. Residents identified protection of the quiet, secluded feel of Mendota Heights’ mature neighborhoods as a priority, and understand that to maintain its neighborhoods it is important to preserve natural features and the environment. To achieve this vision, overarching community goals and policies such as working to reduce airplane noise and protection of the Critical Area underly much of the land use direction described in this chapter. The Future Land Use Plan presented specifically identifies areas planned to stay the same and areas planned for change. The distinction between these two areas allows for targeted development and redevelopment that is intended to support the long-term sustainability of the community, while protecting existing neighborhoods and high quality natural areas that define the character of Mendota Heights. The subsequent sections of this chapter will first describe the city’s land use context within the region. Since Mendota Heights is within the 7-County Metropolitan Area this Plan must be consistent with the Metropolitan Council’s regional plans. The regional context provides the guidelines, while the city’s specific land use plans provide the roadmap and direction for the future of the community. As such, the majority of this chapter focuses on existing land use patterns, the Future Land Use Plan and areas planned for change within this Planning Period. 2 Regional Planning Designation The City of Mendota Heights is located within the Metropolitan Council’s jurisdiction and is required to update its Comprehensive Plan for this Planning Period (2020-2040) to be consistent with the regional plan. The following narrative and policies (in gray italic type) are excerpted and paraphrased from the Metropolitan Council’s Thrive MSP 2040 Plan which provides the applicable guidelines to Mendota Heights based on its designation: The regional planning area designation and related policies identify the Metropolitan Council’s expectations for the amount, location, and standards for development. A community’s planning area designation is based on its location, amount of developable land, existing development patterns, planned land uses and availability of infrastructure. The Metropolitan Council’s Thrive MSP 2040 Plan designates Mendota Heights as “suburban.” Suburban communities experienced continued growth and expansion during the 1980s and early 1990s, and typically have automobile-oriented development patterns at significantly lower densities than in previous eras. Community designations are intended to guide regional growth and development for areas that have urban infrastructure in place and the capacity to accommodate development and redevelopment and establish land use expectations including overall densities and development patterns. The Metropolitan Council forecasts that “Suburban” communities will account for 22 percent of the region’s population growth, 27 percent of its household growth, and 43 percent of employment growth over the next three decades. The 2040 Thrive MSP policies for Suburban communities are available on the Metropolitan council website, and include the following: Burnsville Bloomington Eagan Mendota Mendota Heights Minneapolis Inver Grove Heights Lilydale South Saint Paul Sunfish Lake Richfield Saint Paul West Saint Paul Fort Snelling (unorg.)

The past five years has provided greater direction to the city with respect to anticipated growth and as a result requested adjustments to the forecasts initially provided in 2015. The adjusted forecasts for population, household and employment as agreed to by the Metropolitan Council and the City of Mendota Heights are provided in Table 2-1. Table 2-1. Population, Household, and Employment Forecasts 2010 – 2040 2010 2018 2020 2030 2040 Population (% change)11,071 11,340 (2.4%) 12,000 (5.8%) 12,000 (0%) 12,000 (0%) Households (% change)4,378 N/A 4,900 (12%) 5,000 (2%) 5,110 (2.2%) Employment (% change)11,550 N/A 12,600 (9%) 12,900 (2.4%) 13,180 (2.2%) Source: Metropolitan Council, US Census, City of Mendota Heights, SHC As demonstrated in Table 2-1, the city is planning for some household growth between 2020 and 2040. Most of the household growth is anticipated to occur in areas designated for mixed- use, which is likely to be primarily multi-family development. As a result of this development pattern, the population is expected to remain generally constant as the number of persons-per- households shrinks. The city’s employment is anticipated to grow over this Planning Period but not quite as significantly as contemplated in the 2015 forecasts. While there remains land capacity to support increased business and light industrial development, the growth trends over the past 5-years indicate a slightly slower rate of employment growth adding approximately 580 jobs over the next 20-years to the community. GOALS & POLICIES The goals and policies set the direction for the community and describe the land use aspirations that the city hopes to achieve for this Planning Period. An important part of this Plan is to communicate to residents, business owners, and stakeholders the vision using a combination of goals, policies and maps. To that end, the goals and policies that follow focus on existing and future land uses and are intended to directly support the Future Land Use Plan contained in subsequent sections of this chapter. 6 Chapter 2 - Land Use & Growth City of Mendota Heights 2040 Comprehensive Plan Update GOAL 1: The Future Land Use Plan will provide the foundation for all land use decisions in Mendota Heights. Policies 1.Development and redevelopment of housing, businesses, transportation systems, parks and community facilities shall be done in accordance with this Plan. 2.This Plan shall be reviewed and amended as necessary to ensure development policies are consistent with the city’s vision for current and future development decisions. 3.Any zoning and/or rezoning decisions shall conform to the Future Land Use Plan. 4.The Future Land Use Plan should be periodically updated to reflect changing priorities and conditions of the city, or if needed to conform with the Metropolitan Land Planning Act. 5.The city will strive to create a balanced land use pattern that provides appropriate designations that meet projected growth and market demand. GOAL 2: Preserve, protect, and enrich the mature, fully developed residential neighborhoods and character of the community. Policies 1.Subdivision and zoning standards will require high quality site and building design in all new developments. 2.The city will emphasize quality design, innovative solutions, and general focus on aesthetics throughout the community, including within existing developments and buildings. 3.Future parks, trails and open spaces will be planned within walking distance of all residential areas, both existing and planned. 4.Development and planning of land will be encouraged to provide reasonable access to the surrounding communities. 5.Public buildings and properties will be designed, constructed and maintained to be a source of civic pride and to set a standard for private property owners to follow. 6.A mechanism will be developed to allow for the maintenance and reinvestment in identified non-conforming properties. 7 Chapter 2 - Land Use & Growth City of Mendota Heights 2040 Comprehensive Plan Update 7.Redevelopment of existing MR-Medium Density Residential and HR-High Density Residential properties are to be limited to densities consistent with the Future Land Use Plan. 8.LR-Low Density Residential development and redevelopment shall avoid creating new “flag lots” if the “flag” has less than 100-feet of frontage. Goal 3: Encourage and support industrial and commercial development in designated areas. Policies 1.The city will use available resources to identify redevelopment needs. This will include cooperation with Dakota County and the Metropolitan Council to achieve redevelopment objectives. 2.Transitions between adjoining land uses will be required for adjacent residential uses, and will be encouraged between compatible land uses (e.g. transition between a general manufacturing and retail use will be encouraged). 3.Amenities within the industrial and commercial districts will be encouraged to promote a more vibrant and attractive place for workers. Goal 4: Work to reduce the impact of aircraft noise throughout the community. Policies 1.Increase public participation and representation on the Noise Oversight Committee (NOC) and with the Metropolitan Airports Commission (MAC). 2. Achieve noise reduction through advocating modified takeoff procedures and corridor compliance. 3.Monitor the continued implementation of the Minneapolis/St. Paul (MSP) Airport Comprehensive Plan. 4. Advocate for specific noise control measures through operational changes and advanced technology. 5. Notify and work with Federal Aviation Administration and other appropriate agencies in the event that potential airspace obstructions are encountered. 6.Consider aircraft noise and safety issues in applicable land use and zoning decisions. 8 Chapter 2 - Land Use & Growth City of Mendota Heights 2040 Comprehensive Plan Update EXISTING LAND USE The city’s developable land is nearly fully developed with a mix of low-density single-family uses, pockets of medium and higher density multi-family housing, commercial nodes and light industrial development. The existing development pattern is expected to remain through this Planning Period, with targeted opportunities for development or redevelopment which are described in subsequent sections of this chapter. The following table indicates how the existing land use is distributed within the city which illustrated on Map 2-2. Existing Land Use. These categories are not the same and do not necessarily correspond to the Future Land Use categories identified later in this chapter.

As previously introduced, Mendota Heights is almost fully developed and the majority of the land use pattern is anticipated to remain the same as it is today. Existing single- family neighborhoods are planned to stay the same, while opportunities for development and redevelopment are concentrated in areas more recently developed such as key transportation nodes and mixed-use areas. This section describes 1) the overall planned future land use pattern of the community; 2) key considerations for areas planned to stay the same, with specific interest on existing neighborhoods; and 3) areas planned for change focusing on areas where new residential and commercial uses may be developed or redeveloped over this Planning Period.

Future Land Use Acreage by Decade. Residential Uses The city’s land uses are predominantly developed with low density single-family uses, with small pockets of multi-family housing located at key transportation corridors and nodes. The trend towards a more balanced housing pattern is recent with eight percent (8%) of the residentially- designated land in the city utilized for multiple family homes or medium to high-density development, which marks a significant increase from one percent (1%) in 1979 and five percent (5%) in 2002. The Future Land Use Plan identifies five categories with residential uses: rural, low density, medium density, high density and mixed-use. •RR – Rural Residential (0.1 - 1.45 DU/Acre) This land use is generally located in the east central part of the city. This designation is intended for large lot single-family residences and includes properties with and without city sewer. The Rural Residential areas are planned with a density not to exceed 1.45 units per acre. The corresponding zoning district classification is R-1A (One Family Residential). •LR – Low Density Residential (2.0 - 2.9 DU/Acre) This land use is the most prevalent land use category in the city and generally allows development of single-family principal and accessory uses. This designation corresponds to the R-1 zoning district, which requires a minimum lot size of 15,000 square feet and minimum lot width of 100 feet. •MR – Medium Density Residential (3.0 - 5.9 DU/Acre) This land use generally allows townhome and attached housing development at suburban densities. New areas of Medium Density Residential are added in this update to include existing townhouse and duplex projects that were previously designated Low Density and zoned R-1, but are actually developed consistent with this land use designation. The corresponding zoning district classifications are: R-2 (Medium Density Residential District) and MR-PUD (Medium Density Residential Planned Unit Development). 13 Chapter 2 - Land Use & Growth City of Mendota Heights 2040 Comprehensive Plan Update •HR – High Density Residential (6.0 - 9.0 DU/Acre) This land use provides for multi-family and apartment development at suburban densities. Most of this land use is in a few large apartment projects. The corresponding zoning district classifications are: R-3 (High Density Residential District) and HR-PUD (High Density Residential Planned Unit Development). City Code includes Planned Unit Developments (PUD) regulations that allow for a varied and compatible development of property by encouraging reasonable flexibility from applicable standards, including higher densities than would be allowed under the underlying zoning district and/or future land use designation. Mendota Heights has approved three (3) high-density residential PUD’s in the community. •MU – Mixed-Use (21.0 - 30.0 DU/Acre for Residential Uses) Undeveloped land guided mixed-use is planned to develop approximately 75% of its acres with residential uses at the densities identified, which is consistent with existing mixed-use projects in the city. The northeast quadrant of the Highway 62 and Dodd Road intersection has been developed into a mixed-use center known as The Village at Mendota Heights. The southeast corner of this includes the Mendota Plaza shopping center which has seen renovation and redevelopment in recent years, including a new Walgreen’s pharmacy; White Pine Senior Living, a 50-unit assisted living complex, and a 4-story 139-unit apartment project developed by At Home Apartments. The current residential development has developed at densities between 21 and 30 dwelling units per acre, and adjacent undeveloped outlots are guided to develop at similar densities. Commercial Uses Commercial land uses are typically divided into three general categories; (1) office, (2) retail, and (3) mixed-use. The office category includes land uses generally considered to be of a limited business nature, typically a daytime office use. Map 2-3. Future Land Use Plan identifies these areas as “LB - Limited Business”. The current and corresponding zoning district classifications are B-1 (Limited Business), B-1A (Business Park) and B-2 (Neighborhood Business). Retail and mixed-use are similar, but the mixed-use designation includes compatible residential uses in proximity. 14 Chapter 2 - Land Use & Growth City of Mendota Heights 2040 Comprehensive Plan Update •LB – Limited Business There are presently four locations where most Limited Business uses in Mendota Heights are currently located or planned: -In the southwest quadrant of Highway 62 and Lexington Avenue; -Either side of Mendota Heights Road, between I-35E and Dodd Road; -On the south side of South Plaza Drive, east of Dodd Road near the Mendota Plaza area; and -On the south side of Highway 13 (Sibley Memorial Highway) at the northern city boundary, east of I-35E. The second category of commercial uses expands the uses to include retail, restaurants, hotels and other commercial uses. This includes neighborhood type convenience stores and shopping centers. Map 2-3. Future Land Use Plan identifies these areas as “B - Business” and “MU - Mixed-Use”. The current and corresponding zoning district classifications are B-3 (General Business), B-4 (Shopping Center) and PUD - Planned Unit Development. •B – Business There are four locations where Business uses are planned: -The southeast quadrant of Highway 62 and Lexington Avenue; -The northeast quadrant of Lexington Avenue and Mendota Heights Road; -The area between Highway 55 to the west, Mendota Heights Road to the north, and Northland Drive to the east/south. -The 14.6 acres assemblage of city-owned parcels, located east of Highway 55, north of Bourne Lane and south of Lemay Shore Drive. The properties are commonly referred to as the “Bourne Lane Site”. Similar to the Business land use designation, the Mixed-Use designation allows for neighborhood types of retail, shops, and includes service businesses such as restaurants, salons, professional services, etc., that are compatible with residential uses. •MU – Mixed-Use The city’s largest concentration of commercial or business uses are located at Highway 62 and Dodd Road, in the Mendota Plaza and The Village at Mendota Heights developments which are both guided mixed-use. 15 Chapter 2 - Land Use & Growth City of Mendota Heights 2040 Comprehensive Plan Update The northeast quadrant of this intersection has been developed into a mixed-use center known as The Village at Mendota Heights. The southeast corner of this includes the Mendota Plaza shopping center which has seen renovation and redevelopment in recent years, including a new Walgreen’s pharmacy. The intent of the district is to allow for mixed-use developments that combine residential, retail, and commercial uses into a coordinated, planned development project. This land use designation is located both north and south of the Highway 62 and Dodd Road intersection, the city’s only significant retail area. These two commercial/residential developments are zoned as MU-PUD Mixed-Use-Planned Unit Development. Industrial Uses •I – Industrial The Industrial land use category is concentrated in the city’s industrial and business park in the southwest part of the city, north of I-494. The vast majority of the 400-plus acres of Industrial land is west of Highway 55, with a portion east of Highway 55 and west of I-35E. This land use includes manufacturing, office, and warehousing uses, but also hotels, and other commercial uses. Public and Open Space Uses •P/S – Public/Semi-Public The Public/Semi-Public land use designation includes various land uses that are generally outside the commercial, industrial and residential categories. Among these are city buildings, such as City Hall, public works and fire stations; schools, both public and private; churches and synagogues; and cemeteries. •P – Park/Open Space The Park/Open Space land use designation includes city, State and regional parks, golf courses and nature preserves. 16 Chapter 2 - Land Use & Growth City of Mendota Heights 2040 Comprehensive Plan Update Areas Planned to Stay the Same As a mostly developed community, Mendota Heights expects the existing land use pattern to continue through this Planning Period with a few exceptions that are discussed in the next section of this chapter. While the city expects existing neighborhoods and commercial nodes to remain, it is important to plan how the city will maintain and preserve existing uses to ensure a high quality of life for all of the community’s residents and businesses. Guiding Properties Accurately To address and protect the city’s single-family uses, and to accurately identify pockets of non- conformity the Future Land Use Plan must reflect accurately the existing and planned uses in the city. A major effort of this planning process was to review the 2030 Plan and to update the Future Land Use Plan so as to reflect either 1) the actual use or development of the property; or 2) to guide the property consistent with the city’s vision for the future. A list of more than 20 properties of various sizes were identified as guided incorrectly since the last Plan update, and all of the identified properties have been appropriately re-guided as part of this planning process (See Appendix F for full list and map location of properties). The process to update the Future Land Use Plan provides the foundation from which the city can determine what areas should stay the same, and what areas provide opportunities for change. Non-Conforming Single-Family Uses Through this planning process the city identified the most significant existing land use pattern issue is that of non-conforming single-family uses. As described throughout this Plan, the city’s dominant single-family land use has resulted in a low density residential development pattern. While the single-family use is broadly consistent across the city, the individual neighborhood patterns vary based on the decade in which the neighborhood was developed. Design and architecture trends change over time and the neighborhoods reflect the market demand of each particular decade resulting in varying housing styles, lot sizes, and configurations. Fast forward to today, and the city is filled with single-family neighborhoods of different character depending on the decade in which it was developed, yet the city applies a uniform zoning and land use standard that results in non-conforming lots and uses all over the city. The city recognizes there are certain areas of the city where single-family lots are generally smaller (mostly platted pre-1985) and have less than the minimum lot size standard of 15,000 square feet per Zoning Code. Many of these lots and structures do not meet current setback standards that result in a property being deemed non-conforming. To fully understand this issue, a mapping analysis was completed as part of this Plan and is shown on Map 2-4. Lot Sizes for 2020 Single- Family Uses. 17 Chapter 2 - Land Use & Growth City of Mendota Heights 2040 Comprehensive Plan Update Over time the city has updated its zoning ordinance affecting lot sizes, setbacks and other dimensional standards. These changes have resulted in single-family parcels becoming legally non-conforming which can pose problems and legal hurdles when homeowners want to improve or expand their dwellings, and in some cases run into setback or lot coverage issues. The city has identified protection and enhancement of existing single-family neighborhoods as a priority in this Planning Period and it is important for property owners to be able to improve and maintain their properties. As a result, the city supports updating the Zoning Ordinance, as part of the Implementation Plan, to provide mechanisms for assisting these legal non-conforming uses, which may permit said uses to be improved or updated without extraordinary measures, such as a variance. Created June 2019, Source: City of Mendota Heights, Dakota County, 2016 Map 2-4. 2020 Single-Family Land Use Lot Size 18 Chapter 2 - Land Use & Growth City of Mendota Heights 2040 Comprehensive Plan Update Areas Planned for Change While the majority of the city is planned to stay much the same as it is today, there are opportunities in the community where new development or redevelopment may occur during and in this Planning Period. The city has identified 22 focus areas, each with different characteristics land use designations and planned future land uses. The city acknowledges that development or redevelopment of these properties may be dependent on market conditions and has made its best estimate as to the timing of development activities. The tables that follow summarize the information contained in the narrative for each property identified in the section titled Focus Areas. Table 2-4 estimates the anticipated residential development or redevelopment of the Focus Areas by decade. As shown, the city anticipates that approximately 210 new households will be developed over the next 20-years, consistent with the revised forecasts shown in Table 2-4 of this chapter. Table 2-5 shows the estimated employment projections for development or redevelopment within the Focus Areas, as well as expansion opportunities of existing businesses. Map 2-5 identifies all Focus Areas overlaid with the Future Land Use Plan. Development and redevelopment opportunities comprise diverse land use designations allowing for a variety of potential land uses to be developed in this Planning Period. There is no “staging” plan because infrastructure and utilities are generally available throughout the city. Any site development or redevelopment will likely need site specific improvements, but utilities will either already be on-site or adjacent to the site. As such development or redevelopment could occur anywhere within the city and still be contiguous to infrastructure. The city does believe that the mixed-use areas are most likely to develop within the 2021-2030 time period given current market demand and proximity to existing mixed-use development in the city. This is indicated by the anticipated household development shown in Table 2-4. 19 Chapter 2 - Land Use & Growth City of Mendota Heights 2040 Comprehensive Plan Update Table 2-4.

Chapter 3 - Transportation City of Mendota Heights 2040 Comprehensive Plan Update 1 3 TRANSPORTATION Mendota Heights is strategically located within the regional roadway system, with access to major highways connecting to both downtown Minneapolis and downtown St. Paul, MSP Airport, and all parts of the region in all directions. The completion of Interstates 494 and 35E in the late 1980’s altered the physical environment of Mendota Heights. The highway systems have connected the community to the region, and this access has contributed to growth of the residential, commercial, and industrial base of the community; but these major transportation systems have also increased air, noise, and water pollution in parts of the community. This chapter of the plan addresses transportation in many forms – automobiles, transit, bicycles and pedestrians, aviation, and freight.

Policies 1.Transportation improvements will be coordinated with the plans of MnDOT, Dakota County, Metropolitan Council, and adjoining communities. 2.When feasible, the city will support regional improvements to major transportation facilities serving the city. 3.New construction techniques, technologies, and environmental sustainability will be incorporated in planning transportation facilities. 4.A network of sidewalks and trails will be constructed in all new developments and redevelopments, where practical and feasible. 5.Developers will be required to provide the transportation facilities within and adjacent to new subdivisions, including rights-of-way, roadways, and bicycle and pedestrian facilities necessary to support their development. 6.Existing transportation facilities will be maintained so as to preserve or improve service levels and minimize life-cycle costs, including an ongoing pavement management program for city streets. 7.Where practical and feasible, planning for roadway improvements will include landscaping, street lighting (where deemed appropriate), and other aesthetic improvements. 8.Advocate for transportation improvements outside of Mendota Heights, as identified in the Dakota County Regional Roadway Visioning Study. 9.Investigate funding alternatives that would reduce or eliminate the need for special assessments. Chapter 3 - Transportation City of Mendota Heights 2040 Comprehensive Plan Update 3 GOAL 2: Expand transit options that serve Mendota Heights. Policies 1.The city will continue to support and participate in efforts to implement proposed improved transit service in the city. 2.The city will support the appropriate transit agencies in the seeking of county, regional, state or federal funding to expand transit services in and around the city. 3.The city will support park and ride facilities if demand is met or requested by the residents and/or local businesses. Transportation Analysis Zones In order to develop forecasts and plan for regional roads and highways, the Metropolitan Council needs to know the demographic forecasts for smaller geographic areas within a community, known as Transportation Analysis Zones (TAZ). Each zone provides an estimated allocation of the Metropolitan Council’s forecasts on population, households, and employment within each area. Table 3-1 on the following page is consistent with the 2020, 2030 and 2040 forecasts and estimates. The distribution of future growth within these areas reflects the communities overall land use planning efforts. Map 3-1. Traffic Analysis Zones identifies the eighteen zones geographically that correlate to the tabulated data provided in Table 3-1. Transportation Analysis Zone Estimates for 2020, 2030 & 2040.

Traffic Analysis Zones Map with Metropolitan Council Projected 2040 Population and Employment Chapter 3 - Transportation City of Mendota Heights 2040 Comprehensive Plan Update 6 Functional Classification System Mendota Heights’ street system consists of Principal Arterials, “A” Minor Arterials, “B” Minor Arterials, and community collectors, and a series of local streets. Map 3-2. Transportation Systems illustrates the classification of the roads within the City of Mendota Heights and identifies the number of lanes for all functionally classified roadways. There are no known planned expansions of the City’s functionally classified roadways. •Principal Arterials Interstates 494 and 35E, State Trunk Highway (TH) 55, and the western part of Highway 62 (formerly Highway 110) – from 35E to TH 55 – are all designated Principal Arterials. Interstate 494 forms the southern boundary of the city, while Interstate 35E bisects the city from east to west. Highway 62 bisects the community from north to south, with Highway 55 further dividing the southwestern part of Mendota Heights. •Arterial Roadways “A” Minor Arterials are further classified as minor augmenters, minor relievers, and minor expander roads. The definitions of these classes are outlined in the Metropolitan Council’s 2040 Transportation Policy Plan. The major function of an arterial road is to move traffic from the smaller community collector roads to principal arterials as efficiently as possible. The “A” Minor Arterials within the City of Mendota Heights are Highway 62, (35E to Delaware Avenue), Dodd Road (Highway 149), Highway 13 (Highway 55 to Interstate 494), and Pilot Knob Road or County Road 31 (Interstate 494 to Highway 13). Wentworth Ave West (Dodd Road to Delaware Avenue) is the only roadway currently classified as a “B” Arterial Roadway. Arterial roadways, except county roads, are maintained by the Minnesota Department of Transportation (MnDOT). Traffic on both principal and arterial roadways within the city limits has increased steadily over the last ten years. •Community Collectors Community collector streets are broken down by major collectors and minor collectors. The City of Mendota Heights does not have any minor collectors. Delaware Avenue functions as a major collector on the city’s eastern border. It is otherwise known as County Road 63. Other roads within Mendota Heights that are designated as Collector Streets are: Lexington Avenue or County Road 43, Mendota Heights Road, Marie Avenue, Sibley Memorial Highway, and Highway 13 (Highway 55 to Sibley Memorial Highway). County Roads 8 (Wentworth Avenue and Wachtler Avenue), 63 Delaware Avenue), 43 (Lexington Avenue) and 31 (Pilot Knob Road) are all maintained by Dakota County.

Transportation Systems illustrates the current daily traffic counts, the forecasted 2040 traffic volumes, both in average annual daily trips (AADT), and the existing number of lanes for each roadway. There are no planned or proposed lane expansions of functionally classified roadways as part of this plan. Transportation Issues Mendota Heights commissioned a North-South Mobility Traffic Study to compile data from existing traffic studies into one complete study for the city to use in identifying needed improvements. While the city continues to study various roadway intersections, at this time there are no known or identified road rights-of-way identified within this Plan. New right-of- way needed to serve a development or redevelopment will be required to be dedicated at time of platting consistent with the city’s ordinances. Previous Studies The need for this study was prompted in response to multiple major growth plans surrounding the study area. Inver Grove Heights Northwest Expansion and the Minnesota Vikings Headquarters and Mixed-Use Development Alternative Urban Area-Wide Review (AUAR) planning documents identified traffic and impacts for each development respectively, but neither document examined the combined impact of both developments. The intersections for each study were also primarily south of I-494 along Dodd Road and Argenta Trail and did not fully consider the impacts of traffic traveling to the north of the study areas into the City of Mendota Heights. In addition to the two AUARs, this study also incorporated two other Mendota Heights’ expected future developments. These impact studies and other past studies that were used to provide a basis for this project included: •Inver Grove Heights Northwest Expansion AUAR (Sept 2007) •Regional Roadway System Visioning Study (Aug 2010) •Vikings Headquarters & Mixed-Use Development AUAR (April 2016) •Mendota Plaza Expansion Traffic Impact Study (Aug 2016) Chapter 3 - Transportation City of Mendota Heights 2040 Comprehensive Plan Update 9 •Dodd Road Trail Feasibility Study (Nov 2017) •Linden Street Senior Housing Traffic Impact Study (Dec 2017) •Viking Lakes Event Travel Demand Management Plan (Jan 2018) Study Intersections Key intersections in the study area were identified by Mendota Heights’ staff that could be impacted by future development. These intersections included the following list on each study corridor: •Dodd Road at: -I-494 South Ramps -I-494 North Ramps -Mendota Heights Road -Lake Drive -Wagon Wheel Trail/Decorah Lane -South Plaza Drive -Highway 62 (formerly Highway 110) -Market Street -Maple Street -Marie Avenue -Wentworth Avenue •Delaware Avenue at: -O’Neill Drive -Mendota Heights Road -Huber Drive / Charlton Road -Highway 62 •Mendota Heights Road and Lake Drive •Lake Drive and Swan Drive Chapter 3 - Transportation City of Mendota Heights 2040 Comprehensive Plan Update 10 Existing Traffic Operations Existing traffic operations were analyzed to identify intersection delay and level of service (LOS) based on Highway Capacity Manual (HCM) guidance. LOS grade values correspond to specific traffic characteristics within a given system. At intersections, LOS is a function of average vehicle delay. For two-way stop controlled intersections, minor approach delay is reported in addition to intersection LOS results. LOS “E” or worse, according to MnDOT standards, is considered deficient under normal traffic operations. Results of the existing traffic operations analysis identified several intersections and operational deficiencies in the study area. Noteworthy deficiencies include: •Dodd Road at Highway 62 has unacceptable operations in the AM peak hour and approaching capacity in the PM peak hour. The queues in the AM peak hour spill back to cause unacceptable conditions and block movements at Market Street. •Delaware Avenue at Highway 62 is approaching capacity. Existing Traffic Control Warrant analysis results showed that signal warrants were met for all existing signalized intersections. For the un-signalized intersections that were analyzed, existing all-way stop intersections at Marie Avenue and Wentworth Avenue met Multi-Way Stop Application (MWSA) and 70% signal warrants for four hour and peak hour conditions. The remaining two way stop control intersections did not meet signal or MWSA warrants under their current volume conditions. Chapter 3 - Transportation City of Mendota Heights 2040 Comprehensive Plan Update 11 FUTURE CONDITIONS Traffic projections were developed for 2040 to evaluate operating conditions under both existing and proposed roadway infrastructure. Multiple 2040 traffic scenarios were developed to determine the impact from major developments that are under construction or planned in the area. 2040 Base Scenario •Based on traffic projections from 2030 Dakota County Comprehensive Plan extrapolated to 2040. •Includes planned Mendota Plaza development near Dodd Road and Highway 62. •Does not include the new Viking Lakes development (Minnesota Vikings practice facility and adjacent development) or the planned Inver Grove Heights Northwest Expansion. 2040 Build Alternative Urban Area-Wide Review (AUAR) - No Interchange Scenario •Includes 2040 base scenario traffic growth assumptions as well as traffic generated by the Viking Lakes site and Inver Grove Heights Northwest Expansion. Trip generation for the Viking Lakes and Inver Grove Heights Northwest Expansion sites are based on information in the respective AUAR documents for each site. •Does not assume a future Argenta Trail/I-494 Interchange. •Assumes the most densely developed Viking Lakes scenario that was considered in the AUAR. Chapter 3 - Transportation City of Mendota Heights 2040 Comprehensive Plan Update 12 Viking Lakes Development Details The Viking Lakes development is in the southeast quadrant of the I-494 and Dodd Road interchange. The site will include the new Minnesota Vikings practice facility and associated office space, other offices not affiliated with the Vikings, hotels, retail, and apartments. During typical operating conditions (i.e., no major events occurring at the Vikings facilities), the following traffic volumes are expected to be added to the surrounding roadway network compared to existing conditions: •40,000 daily trips •3,100 AM peak hour trips (74 percent entering/26 percent exiting) •3,800 PM peak hour trips (35 percent entering/65 percent exiting) Viking Lakes Event Traffic As part of a separate study, a Travel Demand Management Plan was developed for the Viking Lakes site to best accommodate traffic during atypical event conditions such as Vikings training camp, high school athletic events, concerts, etc. This event plan looked at events between 500 and 7,200 attendees for existing events and up to 21,000 attendees for future events. However, vehicle traffic to and from the event site will be much lower due to transit/walk/bike and vehicle occupancy which decreases the maximum vehicles to 2,495 for existing events and 7,280 for future expanded capacity events. Many events will occur during off-peak time periods, during weekends, midday, or evening, where total volume splits using Dodd Road or Delaware Avenue are expected to be less than peak volumes. Therefore, the North-South Mobility Study will only evaluate typical operating conditions in the area. Results from the ongoing Travel Demand Management Plan will be considered in recommendations made in the North-South Mobility Study to ensure consistency between analyses and recommendations across studies. Inver Grove Heights Northwest Expansion Development Details The planned development covers a 3,140-acre area in Inver Grove Heights that is generally bound by I-494, Argenta Trail, TH 55, and Babcock Trail. Land uses include low, medium, and high density residential, commercial, office/industrial, public/institutional, and open space. Chapter 3 - Transportation City of Mendota Heights 2040 Comprehensive Plan Update 13 The development is expected to add the following traffic volumes to the surrounding roadway network: •102,200 daily trips •5,300 AM peak hour trips (49 percent entering/51 percent exiting) •8,400 PM peak hour trips (47 percent entering/53 percent exiting) Traffic Forecasts Traffic projections for both 2040 Base Scenario and 2040 Build Scenario conditions were developed based on trip generation assumptions that are described above. This included the development of 2040 daily traffic projections as well as AM and PM peak hour turning movement projections. Origins and destinations of site generated trips were assumed after a review of prevailing traffic patterns and previous documentation. Adjustments were made based on existing regional travel patterns which differed slightly from the Viking Lakes AUAR. It is expected that six percent of Vikings Lakes development traffic will use Dodd Road and nine percent will use Delaware Avenue between I-494 and Highway 62. Six percent of Inver Grove Heights Northwest Expansion development traffic will use Delaware Avenue to the north of I-494. Future Traffic Operations Increased traffic volumes through 2040 are expected to trigger many operational deficiencies throughout the study area, especially in the 2040 Build Scenario with added traffic from the Viking Lakes and Inver Grove Heights Northwest Expansion developments. The 2040 Build Scenario is expected to trigger LOS F at all Dodd Road study intersections north of Wagon Wheel Trail and at all Delaware Avenue/Argenta Trail study intersections, except at Huber Drive. Daily trips on Dodd and Delaware are projected to increase to levels creating unacceptable conditions at various city intersections. Although some solutions lie within the city itself, rising levels of “pass through” traffic from development to the south of the city need to be addressed. This must be accomplished through a regional traffic plan that involves Mendota Heights, Inver Grove Heights, Eagan, MnDOT and Dakota County. This should be a formal process with clear goals and objectives. Chapter 3 - Transportation City of Mendota Heights 2040 Comprehensive Plan Update 14 Future Traffic Control Minnesota Manual on Uniform Traffic Control Devices (MUTCD) warrants were evaluated with projected 2040 volumes to identify potential traffic control revisions throughout the study area. Intersections that were identified as being deficient in existing or 2040 conditions were analyzed under several options to provide improvements to the intersection. Several options per intersection were identified as possible improvements, with a recommended option being identified for each intersection. To maintain a complete corridor vision, intersections were grouped together based on their existing control and location. High level cost estimates were included for comparison purposes only. They represent high-level estimates and do not include right-of-way costs. MN Highway 62 Intersections The MN HWY 62 intersections with Dodd Road and Delaware Avenue are both high traffic volume intersections. With 37,500 daily entering vehicles at Dodd Road and 35,000 daily entering vehicles at Delaware Avenue, both intersections are approaching the capacity of their existing four-lane highway footprint. With 2040 volumes identifying growth up to 50,000 daily entering vehicles for both intersections, an alternative corridor design or interchange will likely be necessary in the future. Market, Maple, and South Plaza Drive The four intersections adjacent to the Highway 62 and Dodd Road intersection were identified as having deficient 2040 intersection operations. Dakota County recommends at least 1/4 mile spacing for signals along a major arterial roadway precluding a signal at either Market Street or North Plaza Drive. The queuing from Highway 62 would also impact closely spaced signals. If all four access locations were unchanged, signal warrants for the four intersections are expected to not be met. However, if access is reduced at Market Street and N Plaza Drive, the resulting traffic shifts would warrant signals at Hilltop Road/Maple Street and South Plaza Drive. The results of the analysis showed that when queuing was minimized at Dodd Road and Highway 62 that operations were generally acceptable at South Plaza Drive, Market Street, and Maple Street. By reconfiguring to a reduced access design, delays at the study intersections were decreased from unacceptable to acceptable conditions. Although right-in right-out access at N Plaza Drive was modeled and preferred, the option of keeping southbound access into Mendota Plaza should be considered in the future. Chapter 3 - Transportation City of Mendota Heights 2040 Comprehensive Plan Update 15 Marie and Wentworth Dodd Road intersections with Marie Avenue and Wentworth Avenue are both slightly skewed all-way stop controlled intersections. With volumes on Marie and Wentworth expected to increase from 3,000-4,000 existing to 5,000-6,000 in 2040 cross street traffic will drive the need for an alternative intersection that will benefit both safety and operations. Wagon Wheel Trail and Decorah Lane With MnDOT’s 2018 TH 149 reconstruction project, Wagon Wheel Trail and Decorah Lane will be reconstructed into a three-lane segment with a pedestrian crossing median between the intersections. This improvement is a near-term solution to increase both vehicle and pedestrian safety at the intersection. However, as volumes increase on Dodd Road this intersection will have future unacceptable operations and long-term alternatives will need to be considered. Delaware Avenue Delaware Avenue is expected to see the highest percentage increase in development traffic in the study area. Volumes are expected to increase from 3,000 daily trips to more than 13,000 daily trips in the full build scenarios. If these volumes are not mitigated, Delaware Avenue will be at capacity with several intersections that have unacceptable conditions. The future Argenta Trail interchange in the adjacent City of Inver Grove Heights, is expected to be installed at or near a location 1,500 feet east of the existing overpass on I-494. This new intersection location is the preferred option; the City of Mendota Heights supports the location and building of this intersection. It is expected that 90 percent of development traffic using Delaware Avenue will be shifted to using the Argenta Interchange restoring the acceptable operations of the corridor in the 2040 Base Conditions. If the interchange is not built, long-term alternatives and options will need to be explored and considered by the city and affected jurisdictions. Chapter 3 - Transportation City of Mendota Heights 2040 Comprehensive Plan Update 16 Multimodal Considerations Although this study was focused on identifying vehicular traffic due to regional development, bike and pedestrian facilities are an important consideration for the final corridor vision. In depth pedestrian and bike facilities were not analyzed as part of the current study (as a previous trail study was finished in Nov 2017). Many of the alternative recommendations will coincide with multimodal improvements and will be analyzed in depth during preliminary design of the concepts. The Dodd Road Trail Feasibility Study (Nov 2017) identified Dodd Road as a major N-S regional trail facility. The existing facilities are mostly on-street trails (wide shoulders) however north and south of Highway 62 there are existing sections of off-street trails. A pedestrian/bike tunnel was just recently constructed under Highway 62 connecting these two segments. Trail crossings were also proposed at Wagon Wheel Trail / Decorah Lane as part of the TH 149 resurfacing project in addition to existing crossings at Mendota Heights Road, South Plaza Drive, and Marie Avenue. The recommendations of the study were to build several additional sections of off-street trail segments along Dodd Road with public support as construction would require property owners to sell property or easements for the trail segments. Due to the limited right-of-way along Delaware Avenue, pedestrian accommodations in the study area between I-494 and Highway 62 would be constrained by roadway grade profiles and right-of-way needed from property owners. Existing off-street trails on Huber Drive and Mendota Heights Road allow connections from Delaware Avenue to the west and serve as alternative multimodal routes to the narrow corridor. Highway 62 Pedestrian Underpass Tunnel Chapter 3 - Transportation City of Mendota Heights 2040 Comprehensive Plan Update 17 Access Management Access management is the planning, design, and implementation of land use and transportation strategies that maintain a safe flow of traffic while accommodating the access needs of adjacent development. The Minnesota Department of Transportation (MnDOT) has set up access management guidelines which provide numerous benefits such as, reduce congestion and crashes, preserve road capacity and postpone the need for roadway widening, improve travel times for the delivery of goods and services, ease movement between destinations, and support local economic development. To provide safe and convenient travel within the city, access management guidelines will be applied when making development decisions. MnDOT access management guidelines will be incorporated into this Comprehensive Plan update. 1.Think land use AND transportation. Before approving a subdivision or rezoning, consider what road design and improvements will be needed to support the develop- ment and link it to the surrounding area. 2. Identify and plan for growth areas. Incremental and uncoordinated development will not lead to a livable community or a healthy business climate. Support eco- nomic growth by planning and investing in a local road network to support development. 3. Develop a complete hierarchy of roads. A viable community requires a variety of roadways organized as an integrated system. Highways and arterials are needed for longer, higher speed trips. Local streets and collectors provide access to homes and businesses. Recognize that different roads serve different purposes. 4. Link access regulations to roadway function. Access requirements in zoning and subdivision regulations should fit each roadway’s functional classification. Recognize that the greatest access control is needed for those roads in- tended to serve longer, higher speed trips. 5. Avoid strip development. Promote commercial nodes. Commercial development can be located adjacent to and visible from the highway, but should be accessed via a system of parallel lo- cal roads and side streets that complement the state highway system. 6. Connect local streets between subdivisions. Give residents convenient options for travel from one neighbor- hood to another by connecting local streets from one subdivision to the next. 7. Design subdivisions with access onto local streets. Avoid lot designs with driveways that enter onto major state or county highways. Orient business and residential driveways to local streets that feed onto the highway at a few carefully de- signed and spaced intersections. 8. Practice good site planning principles. Locate entrances away from intersection corners and turn lanes. Provide adequate space on the site for trucks to maneuver and for vehicles to queue at drive-through windows without backing or stacking on the roadway. Adjacent businesses should provide shared driveways and cross access, so customers can make multiple stops without entering the arterial. 9. Correct existing problems as opportunities arise. Adopt a long range vision for improving access along older, de- veloped corridors. Correct unsafe accesses as individual parcels expand or redevelop. Work with affected property owners to con- solidate driveways and provide internal access between parcels. Fill in the supporting roadway network with local access roads as part of the redevelopment process. 10. Coordinate local development plans with Mn/DOT and coun- ty road agencies. Share plans for subdivisions, rezonings, and site plans with af- fected road authorities early in the development process. Con- tact Mn/DOT and the County Highway Department to talk about long range plans and development needs. MnDOT Access Management Guidelines Chapter 3 - Transportation City of Mendota Heights 2040 Comprehensive Plan Update 18 Bicycles and Pedestrians Mendota Heights installed its backbone trail system in 1989 as part of an approved referendum. The backbone trail system connects residents to amenities throughout the city. In addition to city trails, Dakota County provides regional trail connections identified as greenways. Dakota County Trails are noted as follows: Big Rivers Regional Trail Located along the northern edge of Dakota County from Eagan to Lilydale, the Big Rivers Regional Trail is a scenic 4 1/2-mile paved trail that overlooks the confluence of the Minnesota and Mississippi Rivers. The trail also links to the 72-mile Mississippi National River and Recreation Area, hundreds of miles of trails throughout the greater Twin Cities area and historic landmarks including Fort Snelling, Pike Island and, one of Minnesota’s oldest settlements, the City of Mendota. The Big Rivers Trailhead provides access to a nearly flat paved trail built on an abandoned railroad bed. Highway 55 in Mendota Heights, Interstate 494 in Eagan, and Interstate 35E in Mendota Heights are additional access points to the Big Rivers Regional Trail. Mendota-Lebanon Hills Greenway The Mendota-Lebanon Hills Greenway is proposed to travel 8.5 miles through Mendota Heights, Inver Grove Heights, and Eagan. Today, the landscape is largely suburban. Remaining agricultural areas, primarily in Inver Grove Heights’ Northwest Area, are expected to develop over the next 20-30 years. This will allow for future development patterns in this area to be organized around and shaped by the greenway’s natural, cultural, and recreational amenities.  An underpass crossing of Highway 62 was opened in 2017. Chapter 3 - Transportation City of Mendota Heights 2040 Comprehensive Plan Update 19 River to River Greenway The “River to River Greenway” connects Lilydale, Mendota Heights, West St. Paul and South St. Paul. The trail is in place between Robert Street and the Mississippi River in South St. Paul. Future construction projects will link Valley Park in Mendota Heights to the area near Dodge Nature Center in West St. Paul. These and all other trail systems throughout the community are further described and illustrated on Map 4-2. Bicycle Facilities and Plan, contained in the following Chapter 4: Parks & Open Space. TRANSIT PLAN Public Transit Service Mendota Heights is within Market Area III and IV of the Transit Market Area classifications. Map 3-3. Existing Transit System identifies the existing transit system options located in the City. Market Area III emphasizes commuter express bus service with suburban local routes providing basic coverage. General public dial-a-ride services supplement where regular-route service is not available. Regularly scheduled transit route service is provided by the Metropolitan Council Transit Operations (MCTO). There are six (6) transit routes that operate within the City of Mendota Heights. These bus routes provide service to downtown Minneapolis, St. Paul, the University of Minnesota, the Mall of America, as well as other suburban areas, including Eagan, Inver Grove Heights, and West St. Paul. Several express routes, as well as local limited routes, are available for use by community residents. The city does not have designated Park and Ride facilities or MnPASS lanes. The city will support park and ride facilities if demand is met or requested by the residents and/or local businesses. Metro Mobility, which serves people who need specially-equipped vehicles for transportation, is offered throughout the Twin Cities and within the Metropolitan Urban Service Area. Chapter 3 - Transportation City of Mendota Heights 2040 Comprehensive Plan Update 20 Transportation services for seniors and persons with disabilities is provided by Dakota Areas Resources and Transportation for Seniors. DARTS Loop Transportation services are provided in the neighboring communities of West St. Paul and South St. Paul, which offers transit options for residents tailored to the community preferences, with affordable all-you-can ride fares, and allows riders to get on and off any stops along a continuous one-hour LOOP route. The City of Mendota Heights should explore or seek reliable transit and transportation alternatives for its residents, especially as the community’s population ages.

The corridor is bound by I-35E on the west and the Mississippi River on the east. Existing and projected conditions such as population and employment growth, changing demographics, limited transit service coverage, increased roadway congestion, and lack of planned roadway improvements drove the need to consider transportation alternatives. Short and medium term recommendations were formulated to correspond with the long term vision for the Robert Street Corridor. Short term recommendations focus on enhancements to the existing bus service and commencing studies of land use and parking policies. Medium term recommendations require additional sources of funding to significantly expand bus services. The long term vision of the Robert Street Corridor is to build a transit way from downtown St. Paul to Rosemount linking major destinations. The proposed Robert Street transit way alignment is east of the City of Mendota Heights. However, the long term vision would directly affect the roadways within city limits. The plan presents a limited stop Bus Rapid Transit (BRT) line on Highway 62 and an express bus route on TH 55 which would connect to the existing Light Rail Transit (LRT). The citizens of Mendota Heights would also benefit from additional park and ride facilities within nearby cities. Aviation Plan Mendota Heights benefits from its close proximity to Minneapolis-St. Paul International Airport (MSP) but is also directly affected by aircraft operations. Residents and businesses have easy and quick access to a major international airport. However, aircraft noise is a major issue for some in Mendota Heights because of the detrimental impacts of increased operations on the quality of life in existing neighborhoods and the impact of land use compatibility guidelines and noise contours on development options. Chapter 3 - Transportation City of Mendota Heights 2040 Comprehensive Plan Update 22 Since the opening of the “North-South” runway, previous issues with the distribution of air traffic have been reduced. All residential areas in Mendota Heights were in conformance with the original aviation guidelines and their previous projections of air noise and air traffic. Mendota Heights was the only city that adopted the original Metropolitan Council noise zones and guidelines and is the only city to adopt and enforce a Noise Attenuation Ordinance. The Runway Use System at MSP relies heavily on “land compatibility” as a guiding principle for departure determination, thereby increasing the volume of traffic and the percentage of exclusive use of the southeast corridor, which was zoned commercial/ industrial in cooperation with regional and local planning agencies. This increased traffic has impacted existing compatible residential neighborhoods in Mendota Heights. The City of Mendota Heights has worked diligently to address airport noise issues. A citizen Airports Relations Commission has been established by Mendota Heights to provide recommendations to the City Council on airport issues. This plan is a compilation of the city’s work and history regarding the airport, a set of policies and actions to guide future decisions on airport, a description of the conflicts with other agencies responsible for airport impacts, and a discussion of the potential land use impacts from agency requirements. In addition to these local efforts, the city has adopted a zoning ordinance consistent with federal requirements for height control jurisdictions. The city refers to and utilizes Map 3-4. MSP Airport Safety Zones, Noise Contours and Airspace Heights Limits when analyzing or approving new developments in these airspace zones. Seaplane Use There are no surface waters designated for seaplane use, or as a seaplane base, by the Minnesota Department of Transportation (MnDOT) in the City of Mendota Heights.

City of Mendota Heights June 2019 Source: City of Mendota Heights & MetropolitanAirport Commission FIGURE 3-4 Chapter 3 - Transportation City of Mendota Heights 2040 Comprehensive Plan Update 24 AVIATION-RELATED GOALS & POLICIES GOAL 3: Reduce negative airport impacts in Mendota Heights; and work diligently with all noise issues and agencies to decrease aircraft noise in volume and to decrease the area of noise impacts. Aircraft Noise Policies 1.Increase public participation and representation through the Noise Oversight Committee (NOC) and the Metropolitan Airports Commission (MAC). 2.Achieve noise reduction through advocating modified takeoff procedures and corridor compliance. 3.Monitor the continued implementation of the Minneapolis/ St. Paul (MSP) airport Comprehensive Plan. 4.Advocate for specific noise control measures through operational changes and advanced technology. 5.Notify and work with MAC in the event that potential airspace obstructions are encountered. 6.Advocate for an equitable distribution of aircraft traffic and a more equitable runway use system. History of Noise Reduction Efforts The City of Mendota Heights has addressed aircraft noise issues in several ways, including the following formal actions: 1.Membership in the NOC. 2.Modification of the Land Use Plan consistent with the established aircraft flight corridor. 3.Adoption of the Aircraft Noise Attenuation Ordinance. 4.Establishment of the citizen Airports Relations Commission (ARC) to study airport issues and make recommendations to the City Council. 5.Agreement to a contract with MAC prohibiting construction of a third parallel runway. Chapter 3 - Transportation City of Mendota Heights 2040 Comprehensive Plan Update 25 The city has worked through the various agencies on issues including: modification of aircraft landings and departures, supporting the installation of Airport Noise and Operations Monitoring System (ANOMS), supporting the prohibition of Stage II aircraft, and educating homeowners about the Part 150 program. The City of Mendota Heights planned its land use according to the flight corridor, as originally established, and adopted land use guidelines into an ordinance format in 1987. Operations have strayed to existing residential areas outside of the planned corridor however, significantly impacting several neighborhoods. Impacts of Future Land Use Planning Mendota Heights has planned its land uses in relation to the city’s experience with aircraft noise and the airport’s aviation guidelines. New development and redevelopment in the areas affected by air noise is closely scrutinized and has been accomplished with success through strict adherence to site planning and building design regulations. The City of Mendota Heights has adopted the Metropolitan Council’s model Sound Attenuation Ordinance and has enforced the provisions of this ordinance for all building permits in the Noise Zones since 1986. Town home projects are considered to be consistent with the Aviation Policy compatibility guidelines for Noise Zone 4, which allows residential land uses, as a conditional use. The conditional use for residential land use in Noise Zone 4 is satisfied through the enforcement of the city’s Sound Attenuation Ordinance, thereby, allowing residential construction to meet the Aviation Guide Plan’s land use compatibility guidelines. Freight Plan Freight is an important aspect in supporting a community by providing residents and business with the goods and materials they need. The Twin Cities area is a primary freight hub for the upper Midwest region. Roadways, railroads, barges, and air are the four modes of freight transportation within the Twin Cities Metro area. Mendota Heights does not have any Air/Truck, Barge/Truck, or Rail/Truck freight terminals. See Map 3-5. Metropolitan Freight Systems. Truck freight primarily impacts the city with two US Interstates located within the city limits. I-494 and -35E both carry large amounts of commercial commerce to and from the downtown Minneapolis/St. Paul area (see Map 3-6. Heavy Commercial Volumes (HCAADT). No local roadways have been identified as creating significant issues for the movement of goods within the City of Mendota Heights. See Map 3-7. Twin Cities Freight Railroads.

These facilities represent unique features in a park system that helps to shape the character of Mendota Heights beyond the ordinary. They offer a visual identity to the city, in addition to contributing to the quality of life for those who live and recreate in the community. Mendota Heights has over 771 acres of parks and open space, which includes city parks, both active and passive recreation areas, along with other state and private parks and open spaces. The 33 miles of city trails and bicycle facilities located adjacent to roadways or meandering through the bounty of open space in the community offer an excellent opportunity for exercise and relaxation. Opportunities for walking, bicycling, bird watching, cross country skiing, golfing and nature hiking are sprinkled throughout the community. The city’s parks are supplemented by three golf courses: Mendakota Golf Course, Somerset Golf Course, and the Mendota Heights Par 3 golf course that contribute to open space views and recreational opportunities for residents. 4 Chapter 4 - Parks & Trails City of Mendota Heights 2040 Comprehensive Plan Update GOALS and POLICIES GOAL 1: Provide a park system that is safe, accessible, and equitable in its offerings to all of Mendota Heights’ residents, stakeholders and visitors.

As development has occurred, parkland has been dedicated to provide residents with recreational opportunities. Since the adoption of the 1979 Comprehensive Plan, the city has made improvements to many parks and has developed the following new parks: Copperfield Ponds, Hagstrom-King, Kensington, Mendakota, Sibley, Valley View Heights, and Victoria Highlands. The location of these new parks closely resembles Plan recommendations and reflects the city’s commitment to providing park services to all residents as opportunities arise. Not only has the city made improvements and developed new parks, it has also made efforts to maintain and protect existing open space such as purchasing the 17-acre Mendota Heights Par 3 Golf Course. The city also joined with other public entities and purchased the 25.5-acre Pilot Knob area, which will be retained as open space. Protection of the Pilot Knob area as an important Dakota site has been identified as a critical issue for many residents in the city. O ȟéyawahe/Pilot Knob was placed on the National Register of Historic Places in 2017. Existing City Park Facilities and Types Mendota Heights currently has 756.7 acres of lands dedicated to city parks, golf courses, and open space. The city also features part of the Fort Snelling State Park within their boundaries, totaling an additional 849 acres. The city has 17 public parks throughout the community, including Historic Pilot Knob. These parks contain over 295 acres of land area. A brief discussion of the three types of parks that typically comprise a local park system is provided below. The descriptions and standards serve as a guide to the city with respect to park typologies and programming. Other factors, such as proximity to regional or county parks, financing, or major trends in recreation, will also influence the evolution of the city’s park system. Regional and State parks are discussed later in this chapter. 7 Chapter 4 - Parks & Trails City of Mendota Heights 2040 Comprehensive Plan Update 1) Neighborhood Park Neighborhood parks are the foundation of the park system and serve as the recreational and social focus of the neighborhood. They accommodate a wide variety of age and user groups, both children and adults. They create a sense of place by bringing together the unique character of the site and the neighborhood. Mendota Heights should seek to achieve a balance between active and passive neighborhood parks. Neighborhood parks range from 5 to 30 acres and serve a ½-mile area. Communities often will operate a joint neighborhood park with the school district and elementary schools. The city’s neighborhood parks include Friendly Hills, Hagstrom-King, Ivy Hills, Marie, Valley View Heights, Victoria Highland, and Wentworth. 2) Community Park Community parks are designed to meet the recreational needs of several neighborhoods or larger segments of the community. They are intended for ball fields, larger athletic facilities, and community gatherings. They can also be designed to preserve unique landscapes and open spaces. They serve a ½-mile to five mile radius. The city’s community parks include Kensington, Valley, Roger’s Lake, Mendakota, and Sibley Athletic Complex. The city also provides an off-leash dog park only, located off Acacia Blvd., south of the Historic Pilot Knob area. The dog park is on approximately 3 acres of a larger city owned piece of land that is approximately 10.9 acres. The dog park was approved as a temporary dog park under an interim use permit in 2015, and this permit expired in 2020. The city has not yet determined if this dog park 8 Chapter 4 - Parks & Trails City of Mendota Heights 2040 Comprehensive Plan Update will continue, or allow the lands to be developed into an industrial use, which is what the site is guided for under this 2040 Plan. 3) Natural Resource Area Natural resource areas are lands set aside to preserve significant or unique landscapes. They are often, but not always, properties with steep slopes, drainage ways, ravines, or wetlands. In addition, there may be locations where local tree protection, shoreland and critical area ordinances, or state and local wetland ordinances restrict development in some way. Natural Resource areas include Friendly Marsh, Copperfield Ponds, Valley Park, Pilot Knob Preservation, and Dodge Nature Center. Table 4-1.

Parks and Recreational Facilities 10 Chapter 4 - Parks & Trails City of Mendota Heights 2040 Comprehensive Plan Update Trail Facilities Trails for walking, running, biking, and roller blading are very popular. There are 28.5 miles of off-road trails and 4.9 miles of wide shoulders and on-street bicycle facilities currently in portions of the city’s neighborhoods. These trails are both off- and on-road and serve as important connections for recreational opportunities and travel. Improved trail connections are important in Mendota Heights because many residential areas are divided by highways and arterial roads. Access to the Big Rivers Regional Trail is difficult due to the significant elevation changes. As a result, many areas of the community cannot be easily accessed on bikes, roller blades or foot from other areas of the community. Additional or improved trail connections are needed to provide residents access to city parks and other recreational opportunities in the region. Regional Trails Big Rivers Regional Trail: Developed in 1996 by Dakota County along the old Union Pacific Railroad right-of-way, this trail enables residents to bike, walk, and roller blade along the Minnesota and Mississippi Rivers. This trail serves as an important link to other communities and has greatly improved the awareness and accessibility of the River. River-to-River Greenway: This trail serves as a link from Big Rivers Regional Trail through Valley Park to West St. Paul and to South St. Paul. Local Trails and On-street Facilities Mendota Heights has a network of paved and on-street bicycle facilities connecting different neighborhoods in the city. Most bicycle and pedestrian facilities in the city are off-street six to eight- foot-wide bituminous trails. There are also a few on-street bicycle facilities in the community, along Dodd Road, Delaware Avenue, and Decorah Lane. City parks and trails, including other natural resource areas, are illustrated on Map 4-1.

City Park needs can be determined by evaluating the number, size, and accessibility and use of parks. The city meets the National Recreation and Park Association’s recommendation of park land and acreage and will continue to reserve city-owned lands and explore options for expanding additional park and recreation space in the city. Future Trail Connections As part of the 2040 Regional Parks Policy Plan, the Metropolitan Council identified future regional trail opportunities and priority trail corridors. The Regional Bicycle Transportation Network (RBTN) consists of a series of prioritized Tier 1 and Tier 2 corridors and routes. The goal of the RBTN is to establish an integrated network of on-street bikeways and off-road trails which move bicyclists more efficiently and encourage the implementation of future bikeways. Mendota Heights has approximately 6 roadways within Tier 1 RBTN alignments and 1 roadway within Tier 2 RBTN alignments. Providing connections north-south and east-west through Mendota Heights will be critical. Planned trail connections are noted as follows: •Dodd Road Trail Corridor: Dodd Road runs approximately 3.8 miles north- south the entire length of the city. Approximately one mile of this corridor is served by an existing trail, with potential expansion of the trail corridor in the future. Mendota Heights analyzed 2.8 miles of the corridor between Delaware Avenue and Marie Avenue and between Wagon Wheel Trail and Mendota Heights Road. •Planned Bike Lane – Annapolis Street: a bike lane located along Annapolis Street at the city’s northern border (now under construction). •Mendota-Lebanon Hills Greenway: The Mendota-Lebanon Hills Greenway is proposed to travel 8.5 miles through Mendota Heights, Inver Grove Heights, and Eagan. Today, the landscape is largely suburban. Remaining agricultural areas, primarily in Inver Grove Heights’ Northwest Area, are expected to develop over the next 20-30 years. This will allow for future development patterns in this area to be organized around and shaped by the greenway’s natural, cultural, and recreational amenities. 13 Chapter 4 - Parks & Trails City of Mendota Heights 2040 Comprehensive Plan Update •River to River Greenway: The River to River Greenway connects Lilydale, Mendota Heights, West St. Paul and South St. Paul. The trail is in place between Robert Street and the Mississippi River in South St. Paul. Future construction projects will link Valley Park in Mendota Heights to the area near Dodge Nature Center in West St. Paul. •Eagan Soo Line Trail: The City of Eagan and Dakota County have initiated a trail feasibility study in the general area where I-494, I-35E, and TH 55 all come together. This corridor has been identified as a potential regional trail greenway that would connect the Big Rivers and the Mendota-Lebanon Regional Trail corridors. The initial alignment being evaluated includes an abandoned railroad line and two railroad bridges owned by MnDOT. Areas within or adjacent to Highway 55 and I-494 right of way are also identified. These and all other trail systems throughout the community are identified on Map 4-2. Bicycle Facilities and Plan.

It provides outdoor recreation opportunities and natural resource conservation for the public and is considered part of the regional recreational open space system. Fort Snelling State Park is a recreational state park offering swimming, large group and family picnic grounds, a boat launch, interpretive center and historical areas, trails, and scenic overlooks. Most of the park’s active facilities are located on the Bloomington side of the River, requiring most Mendota Heights residents to drive or bike across the I-494, I-35E, and Mendota bridges to access the park. The Mendota Heights portion of the park is left primarily as a natural area as it contains extensive floodplain marsh habitat. Facilities located in Mendota Heights support less intensive uses, such as biking, hiking, cross country skiing, and fishing. The Sibley and Faribault historic sites are also located on the Mendota Heights side.

The nature center is dedicated to the restoration of native plants and animal communities. The center provides excellent educational programs and events for the public, including habitat restoration projects, invasive species removal demonstrations, prairie burns, and native plantings. There are no visitor buildings or restrooms at this location. Trails are open during daylight hours every day of the week; and there are no fees to hike at Dodge Nature Center. Historic Pilot Knob As was noted in Chapter 1, Oȟéyawahe/Pilot Knob is generally located south and west of Highway 55, north of Acacia Boulevard and east of Pilot Knob Road. The 112 acres site is listed on the National Register of Historic Places, and provides an excellent opportunity for the public to visit and experience historic views of the surrounding areas, and learn more about the history and culture of this significant and sacred place. Pilot Knob is a wonderful natural place to read the landscape; watch migratory birds; and to learn more about prairie and oak savanna restoration work currently in progress. Pilot Knob provides a small vehicle parking area, with walking trails, interpretive areas, and gathering spaces. Refer to the image Map 4-3.

Mendota Heights provides a variety of housing choices and work to ensure that existing housing is well maintained. The City of Mendota Heights also encourages the development of new housing that addresses the changing needs of the community. Existing and future residents are looking for more services and amenities near where they choose to live, including convenient shopping options and easily-accessible walking and biking trails.

Estimated Market Value of Owner-Occupied Housing 8 Chapter 5 - Housing City of Mendota Heights 2040 Comprehensive Plan Update The median rent in Mendota Heights is $1,097 per month, which is higher than the Twin Cities Metropolitan Area ($916) and higher than Dakota County ($1,003). Compared to other communities in the area, Mendota Heights’ median rent is slightly higher. This may be attributed to the large number of single-family homes that are rented in the city as well as the development of new, market rate apartment units in the city. Table 5-4 includes median monthly rents in nearby communities. Table 5-4. Median Rent in and around Mendota Heights Community Median Monthly Rent Mendota Heights $1,097 Eagan $1,074 Inver Grove Heights $990 Dakota County $1,003 Twin Cities Metropolitan Area $916 Source: American Community Survey, 2016 Housing Affordability Affordable Housing Stock in Mendota Heights The Metropolitan Council defines an “affordable” home as one costing $85,500, for households making less than 30 percent Area Median Income (AMI), a home costing $153,000 for households making 31-50 percent AMI, and a home costing $240,500 for households making 51-80 percent AMI. In Mendota Heights, the median home value is $351,100, indicating that much of the city’s housing stock is unaffordable at 80 percent AMI or lower. Housing affordability is discussed later in this chapter. These characteristics are summarized in Table 5-5. Affordable Housing Stock in Mendota Heights. Table 5-5. Affordable Housing Stock in Mendota Heights Total Number of All Housing Units 4,693 Number of Affordable Units At or below 30% AMI 31-50% AMI 51-80% AMI 50 311 1,053 Number of Publicly Subsidized Units Senior Housing People with Disabilities All other publicly subsidized units 11 0 0 24 Source: Metropolitan Council 9 Chapter 5 - Housing City of Mendota Heights 2040 Comprehensive Plan Update Cost Burdened Households Many residents in communities across the Twin Cities experience challenges affording their housing costs. The Department of Housing and Urban Development (HUD) defines housing to be affordable if the residents do not pay more than 30 percent of their income towards housing costs. Housing costs can include rent or mortgage payments, utility bills, HOA fees or other fees associated with living in the home. Residents who pay more than 30 percent are considered “Cost-burdened”. In Mendota Heights, over seven hundred households (16.8 percent of households) are considered to be cost-burdened. Table 5-6. Housing Cost Burdened Households outlines the number of cost-burdened households by median income level. Table 5-6. Housing Cost-burdened Households Household Income Level Number of Cost-burdened Households At or below 30% AMI 229 31 to 50% AMI 270 51 to 80% AMI 237 Total Households 736 Source: Metropolitan Council Summary of Existing Housing Needs As demonstrated by the assessment of the existing housing stock the city is dominated by single- family detached uses. While the city is almost fully developed, and redevelopment is unlikely to occur in existing established neighborhoods, it remains important for the city to support programs that assist homeowners with maintenance and upkeep to ensure a sustainable housing stock. This is most important for households that are cost burdened which may make it difficult to maintain large single-family homes and properties. Additionally, the analysis demonstrates the need for additional housing options that are more affordable. As shown in Chapter 1 of this Plan, there is a fairly large senior population which may desire more affordable options, or at the least housing options that are more accessible to services. Secondarily, there is not a huge young-adult population and this could be attributed to a lack of affordable options, and/or a lack of multi-family rental options. Subsequent sections of this chapter describe how areas planned for change or development/redevelopment could support the needs identified in this section by providing additional diversity to the city’s housing stock. 10 Chapter 5 - Housing City of Mendota Heights 2040 Comprehensive Plan Update Housing Projections & Need Although the City of Mendota Heights is relatively built out, it will still need to accommodate for new residents of all socioeconomic backgrounds. The Metropolitan Council has allocated approximately 46 new units of affordable housing (at or below 80 percent AMI) in the city between 2021 and 2030 to meet potential demand. Based on their projections, the city should consider supporting the development of new units that are affordable to different levels, which is provided in Table 5-7. Affordable Unit Allocations for Mendota Heights. Table 5-7. Affordable Unit Allocations for Mendota Heights Household Income Level Number of Units At or below 30% AMI 25 31 to 50% AMI 16 51 to 80% AMI 5 Total Households 46 Source: Metropolitan Council (Revised December 2020) The city’s Future Land Use Plan contained in Chapter 2. Land Use & Growth of this Plan identifies the mixed-use land use category to potentially support the development of affordable housing options in the community. The area guided mixed-use is adjacent to existing, recently developed, multi-family housing which positions the vacant land area for development sometime in the next 10-years. Table 5-8. Future Land Use Designation and Affordable Housing Allocation demonstrates how the Future Land Use designations and corresponding units accommodate the allocated units identified in Table 5-7.

Numerous efforts are available for Mendota Heights to employ in order to facilitate the construction of affordable housing and to expand local housing options including regional, state, and national programs, fiscal devices, official controls, and land use regulation. A summary of key tools are provided in the following pages, and all available tools are provided in Table 5-8. Affordable Housing Implementation Tools. Livable Communities Act In 1995, Minnesota Legislature created the Livable Communities Act (LCA) as defined by Minnesota State Statute 473.25. The LCA is a voluntary, incentive- based approach to help metro area communities address affordable and lifecycle housing needs. The LCA provides funds to communities to assist them in carrying out their development plans for affordable housing and creation of new jobs. Participation in the Local Housing Incentives Program portion of the LCA requires communities to negotiate housing goals with the Metropolitan Council and prepare a Housing Action Plan. Livable Communities Demonstration Accounts (LCDA) LCDA funds support regional growth strategies promoting development and redevelopment that make efficient and cost-effective use of urban lands and infrastructure; improve jobs, housing, transportation, and service connections; and expand affordable and lifecycle housing choices in the region. Funds are available to municipalities that participate in the Local Housing Incentives Program of the Livable Communities Act (LCA). The LCDA is open to local housing and redevelopment authorities, economic development authorities or port authorities in LCA- participating cities, or to counties on behalf of projects located in LCA-participating cities. As the name of the account suggests, LCDA funds are intended to be used for projects that demonstrate innovative and new ways to achieve and implement the statutory objectives, not merely to fill project funding needs. Mendota Heights is a participant of the LCA and would consider further exploration of the program if specific development opportunities become available in the community. Example of a senior living facility 12 Chapter 5 - Housing City of Mendota Heights 2040 Comprehensive Plan Update Local Housing Incentive Account (LHIA) LHIA grants help to produce new and rehabilitated affordable rental and owner occupied housing, and to promote the Council’s policy to expand and preserve lifecycle and affordable housing options to meet changing demographic trends and market preferences, and support the region’s economic competitiveness. Tax Base Revitalization Account (TBRA) The TBRA provides funds to clean up polluted land to make it available for economic redevelopment, job retention, and job growth, or the production of affordable housing to enhance the tax base of the recipient municipality. TBRA funds are raised by a legislatively authorized levy capped at $5 million annually. If the TBRA project includes a housing component, a portion of the housing is required to be affordable. Ownership units are considered affordable if they can be purchased by buyers earning 80% of the area median income (AMI). Affordable rental units are those renting at the Low-Income Housing Tax Credit rent limits based on 50% of the AMI. The city has used TBRA funds in the past for economic redevelopment associated with job growth in the community. The city could explore using TBRA funds in the future, and could consider usage of funds to meet its affordable housing goals. Community Development Block Grant (CDBG) Program The CDBG Program is provided through the U.S. Department of Housing and Urban Development. The CDBG program is a flexible program that provides communities with resources to address a wide range of unique community development needs. The CDBG program works to ensure affordable housing, to provide services to the most vulnerable in our communities, and to create jobs through the expansion and retention of businesses. The city has participated in the CDBG program and will continue to use the resource, as needed or applicable to achieve its housing goals and policies. 13 Chapter 5 - Housing City of Mendota Heights 2040 Comprehensive Plan Update Fiscal Devices Fiscal devices, such as revenue bonds, tax increment financing, or tax abatement can be used to help ease the construction and availability of affordable housing in the City of Mendota Heights. Official Controls Official controls and land use regulation can be used to assist in the construction of affordable housing units. Controls and regulations can also be used to simplify the process of expanding local housing options. Table 5-9. Affordable Housing Implementation Tools is a list of official controls that the City of Mendota Heights can use to implement its housing goals and policies: Zoning Ordinance, Subdivision Ordinance, Building Codes, Design Requirements, lot splits and new home construction, and supports the actualization of the process. These regulatory tools impact the type and cost of new housing. The city will evaluate their official controls within 9-months of adoption of this Plan, and will work to update ordinances and policies to 1) create a more streamlined entitlement process; 2) consider how the policy could support more diversity in housing, especially for seniors and young professionals; and 3) will evaluate policies that may discourage the creation of more affordable housing options in the community. 14 Chapter 5 - Housing City of Mendota Heights 2040 Comprehensive Plan Update Table 5-9 - Affordable Housing Implementation Tools Tools that Address Identified Housing Needs Resources that will be Considered to Address Housing Goals/Needs Experienced and Used Will Explore Unlikely to Use this Tool Local Funding and Support Mechanisms Tax Increment Financing (TIF)X X Tax Abatement X Housing Revenue Bonds X Housing Improvement Areas (HIA)X Accessory Dwelling Unit (ADU)X X Regional, State, and Federal Funding Housing Choice Voucher/Public Housing on Scattered Sites or Project Based (CDA)X Community Development Block Grant (CDBG)X X Housing Rehabilitation Loans (CDA)X X Homecare/Chore Service (DARTS)X X Site Assembly X X MN Housing Finance Agency (MHFA)X First Time Buyer X X HOME Funds (CDA)X X Livable Communities Act - Metropolitan Council (LHIP, LCDA, LHIA )X X Tax Base Revitalization Act X X X Low Income Housing Tax Credit (LIHTC)X HUD Insured Mortgage X X Tax Base Revitalization Account (TBRA)X X Other Housing Initiatives Community Land Trust X Community Development Corporation (Land Bank)X Local Initiative Support Corporation (LISC)X X Vo-Tech Building Programs X X Registration.

Mendota Heights seeks to support its community through a diverse mix of commercial offerings, retention and expansion of employment-generating businesses, and preserving land for commercial and industrial activities with adequate buffering from nearby residential areas. Regional Context The Metropolitan Council recommends including an economic development element in local comprehensive plans to achieve regional goals for economic competitiveness. Providing suitable locations for businesses to succeed, particularly industries that export products or services beyond our region and bring revenue and jobs into the region, is a significant need. The Metropolitan Council defines two key terms related to this element: •Economic Competitiveness – Examining and strengthening the ability of the region to compete effectively and prosper in the global economy. •Economic Development – Activities that directly aim to retain, attract, and grow businesses that bring wealth into a community or region. While the city focuses its efforts on growing businesses within its own boundary, it is also important to understand the context for that growth within the region and work with regional partners to achieve shared success. Part of Mendota Heights regional context is its excellent accessibility within the region from the roadway network and its proximity to MSP International Airport.

GOAL 4: Continue to develop and redevelop community commercial areas that serve the whole community. Policies 1.Provide and support commercial areas to supply convenience goods and services for residents of Mendota Heights. 1.To mitigate conflicts between commercial and residential development, require appropriate land use transitions at the edges of residential neighborhoods through the use of setbacks, screening, buffering and fencing. 1.Require sidewalk connections along major streets leading up to neighborhood commercial centers and direct connections from the public sidewalk to the storefronts. 5 Chapter 6 - Economic Development City of Mendota Heights 2040 Comprehensive Plan Update GOAL 5: Continue to develop business and industrial park areas that provide jobs and serve the local and regional economy. Policies 1.Provide opportunities for new industrial development and expanded employment opportunities to create livable-wage positions in Mendota Heights and the redevelopment of existing industrial uses to serve existing businesses in the community. 2.Provide attractive, planned environments as a means to induce employers to locate within the city. 3.Continue to provide and enforce standards for industrial developments that improve the appearance and character of industrial properties. 4.Provide high quality public services and infrastructure in all commercial and industrial districts. Economic Overview A 2016 report by Tangible Consulting Services evaluated the market and development conditions in preparation for the comprehensive plan update (see attached Appendix G). It provided an overview of the unique demography and economic base that characterizes the city and investigated the market and development factors that may shape future growth in housing, retail, and industrial development. Mendota Heights is mostly developed, which limits opportunities for new development; however, there is a need to stay viable and attractive as the demographics of the Minneapolis-St. Paul metropolitan area shift. The population is growing, it is aging, and more households will be renters. Choices about purchasing and employment will also evolve. Decisions about housing redevelopment, retail support and location, and office and employment opportunities will affect Mendota Heights’ character as a desirable place to live. 6 Chapter 6 - Economic Development City of Mendota Heights 2040 Comprehensive Plan Update Redevelopment and Business Development Opportunities for business investment will likely include retail, business, office and industrial uses. Existing retail areas in Mendota Heights benefit from their visibility from the heavily traveled Highway 62 corridor, and benefit from their distance from other retailers. Their distance to retail centers in the nearby communities of Eagan and West St. Paul gives Mendota Heights’ retailers a competitive advantage for neighborhood goods and services for residents in the surrounding neighborhoods. These locational characteristics are likely to keep the areas strong into the future. Mendota Heights is more limited in its prospects for destination retail given its competition in this category from surrounding communities. The Mendota Heights Industrial District (MHID) is an important contributor to the tax base compared to nearby competing areas. It is in the South Central industrial sub-market of the Twin Cities which encompasses West St. Paul, South St. Paul, Inver Grove Heights, Eagan, Apple Valley, and Burnsville. New industrial development in the South Central Sub-market is coming online more slowly than in the metro area overall. Figure 6-1.

Source: Tangible Consulting 7 Chapter 6 - Economic Development City of Mendota Heights 2040 Comprehensive Plan Update The Mendota Heights Industrial District is attractively positioned for continued business occupancy due to its central location in the region, proximity to the airport, flat topography, diversity of existing tenants, and available utilities. A major challenge is the limited opportunity for on-site facility expansion and few sites for new industrial development. The office buildings in the Mendota Heights Industrial District and the Centre Pointe Business Park operate in a different competitive environment than the industrial facilities. Vacancy rates tend to be higher in office properties. Office developments typically cluster into specialized areas or recognized districts within the metropolitan area, due to transit availability and proximity to amenities. Office buildings in Mendota Heights’ two districts are 20 years old on average and together offer around 1.4 million square feet of floor area. Market indicators are mixed for office buildings in Mendota Heights – the 2016 vacancy rate is lower than the metro as a whole but rents are also lower. Retail Redevelopment Opportunities While there are limited opportunities for additional retail in Mendota Heights, two exist: •Expanding retail opportunities beyond what is already planned at Mendota Plaza and The Village at Mendota Heights along Highway 62 at Dodd Road. •Better capturing the daytime population at the Mendota Heights Industrial District. Small footprint retail and restaurants could better serve these employees. 8 Chapter 6 - Economic Development City of Mendota Heights 2040 Comprehensive Plan Update Industrial Redevelopment Opportunities The Mendota Heights Industrial District Redevelopment Plan makes several recommendations for actions to strengthen the area’s attractiveness to industrial users and invite building renovation and improvement. These include: •Explore ways to communicate, brand, and promote the Industrial District; •Consider city policies toward redevelopment incentives, which will provide a positive impact on future projects or existing business expansion projects; and •Consider investments in broadband and other technology infrastructure as necessary to ensure the area is competitive and serves the business needs. Office Redevelopment Opportunities To support continued viability of the office areas in Mendota Heights, consideration could be given to actions such as: •Strengthen the office identity and branding of the southern part of the Mendota Heights Industrial District; let the district be part of the broader Eagan/Mendota Heights office district; and •Build the amenity base of the area with the addition of some retail and restaurants, even if the opportunities to do so are limited. Education and Workforce A strong, educated workforce supports local businesses and gives Mendota Heights’ residents an opportunity to work and go to school close to home. If a community has daytime workers, it leads to more retail and restaurant offerings since those businesses can now capture a daytime crowd in addition to evenings and weekends. Additionally, residents who can work close to home reduce transportation costs and gain more time in their day that would have otherwise be spent on long commute. Education Mendota Heights is served by public schools, including Somerset Elementary, Mendota Elementary, Friendly Hills Middle School and Henry Sibley High School, all of which are part of Independent School District 197. The city is also home to St. Thomas Academy and Convent of the Visitation School. 9 Chapter 6 - Economic Development City of Mendota Heights 2040 Comprehensive Plan Update There are currently no post-secondary schools located in Mendota Heights, but the city’s central location in the Twin Cities offers many easily accessible post-secondary options. Workforce Mendota Heights has a unique employment profile for a Twin Cities suburb. Businesses in Mendota Heights offer a high number of good-paying jobs and there are almost two jobs in Mendota Heights for every employed person who lives in the city. However, most Mendota Heights workers commute to jobs outside of the city. Of the roughly 5,500 workers who live in Mendota Heights, almost 95% go to work at a location outside the city limits. Only around 300 residents work at a business in Mendota Heights. While some jobs are in a neighborhood serving retail businesses and the community’s educational institutions, the majority of jobs in Mendota Heights are in the industrial facilities and offices in the city’s industrial and office areas. The majority of employment in Mendota Heights is focused in two distinct areas – the Mendota Heights Industrial District and the Centre Point Business Park. Businesses in the Mendota Heights Industrial District (MHID) offer over 7,000 principal jobs. The MHID is home to a mix of industrial and office developments. The Centre Pointe Business Park offers around 800 jobs. The business park was developed in the 1990s and 2000s and is comprised entirely of office buildings. Industrial and office jobs tend to pay a living wage which are higher on average than jobs in some other sectors such as retail stores and services. Mendota Heights 2040 Comprehensive Plan June 2019 Economic Development 6-8 While some jobs are in neighborhood serving retail businesses and the community’s educational institutions, the great majority of jobs in Mendota Heights are in the industrial facilities and offices in the city’s industrial and office areas. The majority of employment in Mendota Heights is focused in two distinct areas – the Mendota Heights Industrial District and the Centre Point Business Park.

The service is free to any Mendota Heights business or resident. Experts help businesses plan by providing information on business start-up or acquisition, creating a business plan, evaluating financials, and analyzing the viability of commercial sites. The West St. Paul Work Force Center is a valuable tool for local job seekers and businesses searching for employees in the surrounding communities. Part of a larger initiative sponsored by the Minnesota Department of Employment and Economic Development (DEED), job seekers have access to job search coaching, information for veterans and people who require special services, training programs for in-demand occupations, and a free online job bank. Businesses can get help finding workers, developing a workforce strategy, locating and expanding their business, and data analysis on the local labor market. The city also partners with the Dakota County CDA on strategic initiatives such as: •Investing in transportation; •Coordinating strategic infrastructure and land development; •Linking workforce development and economic development; •Building the capacity to respond to business prospects; •Providing quality workforce housing; and •Strengthening development-related research and policy capacity. CITY OF MENDOTA HEIGHTS 2040 Comprehensive Plan Update Chapter 7: Natural Resources This page is intentionally blank. 1 Chapter 7 - Natural Resources City of Mendota Heights 2040 Comprehensive Plan Update 7 NATURAL RESOURCES The City of Mendota Heights is fortunate to have a wide variety of natural resources throughout the community. These natural resources are an important recreation, aesthetic, and ecological asset to the community of Mendota Heights. During the city’s developing stages, a strong emphasis was placed on preserving high quality open spaces and woodland areas. Residents enjoy numerous lakes, streams, wetlands, open spaces, parks, trails, and the Mississippi and Minnesota Rivers. These natural areas provide tremendous benefits to the community and its residents and are an important focal point of Mendota Heights. Protect, Connect, Restore and Manage Ecosystems, Plant Communities & Species The quality of life for the community of Mendota Heights highly depends on how it manages its natural resources—the air, minerals, land, water, and biota that form the foundation to life in the city. This chapter is a guide for managing the city’s natural resources in a sustainable way. It will help protect and enhance residents’ quality of life for current and future generations by suggesting strategies to protect, connect, restore and manage ecosystems, plant communities, and species. 2 Chapter 7 - Natural Resources City of Mendota Heights 2040 Comprehensive Plan Update Purpose The environmental benefits provided by the community’s natural resources are essential for human life. Protecting and preserving these natural resources require preventing, and providing treatment for, potential harmful pollutants that can adversely affect the health of our air, water, and soil. Some of the strategies for addressing pollutants include, but are not limited to: stormwater infiltration and treatment, providing flood control, providing and preserving healthy soil for plants, and providing and preserving habitat for pollinators and wildlife. Natural resources can also provide economic value, recreation, health benefits, and aesthetic beauty. Healthy natural resources help ensure that Mendota Heights has a high quality of life that can be sustained for future generations. GOALS and POLICIES GOAL 1: Develop a professional, comprehensive, strategic Natural Resources Management Plan for city-wide natural areas and natural resources. Policies 1.Develop capabilities to monitor and implement the Natural Resources Management Plan through city staff expertise, as well as through partnerships with community groups, volunteers, and adjacent communities and agencies, thus recognizing the interconnectedness of ecosystems. 2.Implement a formal Natural Resources Management and Sustainability Commission to aid in the execution of the strategic Natural Resources Plan. This Commission may begin as a Task Force, whose charge would be to establish the by-laws and city ordinance necessary to establish this commission. 3.Develop site-specific management plans that identify and prioritize opportunities to enhance and protect the city’s high-quality areas and Mendota Heights 2040 Comprehensive Plan June 2019 Natural Resources 7-1 7Natural Resources The City of Mendota Heights is fortunate to have a wide variety of NaturalResources. These natural resources are an important recreation, aesthetic, andecological asset to the community of Mendota Heights. During the City’s developing stages, a strong emphasis was placed on preserving high quality open spaces and woodland areas. Residents enjoy numerous lakes, streams, wetlands, open spaces, parks, trails, and the Mississippi and Minnesota Rivers. These natural areas provide tremendous benefits to the community and its residents and are an important focal point of Mendota Heights. Protect, Connect, Restore and Manage Ecosystems, Plant Communities and Species The quality of life for the community of Mendota Heights highly depends on how it manages its natural resources—the air, minerals, land, water, and biota that form the foundation to life in the City.

The topography of the City of Mendota Heights varies greatly, from floodplains of the Minnesota and Mississippi Rivers to the primary and secondary bluffs of these rivers. The topography of Mendota Heights includes rolling to hilly terrain interspersed with poorly drained depressions that form many ponds and small lakes. Steep slopes occur along the Minnesota and Mississippi river bluffs on the western and northern borders of the city. The majority of the city is dominated by relatively flat terrain at an elevation approximately 200 feet above the river. Mississippi and Minnesota River floodplain also exists on the city’s western border. Elevation in the city ranges from approximately 690 feet along the Minnesota River to approximately 1,030 feet along the city’s northern border with West St. Paul, as illustrated in the Map 7-1. Topography. The surficial geology of Mendota Heights consists of glacial and alluvial (outwash) deposits which cover most of the city. The City of Mendota Heights is within the Twin Cities Formation of the Eastern St. Croix Moraine geomorphic area. This area was formed at the southern extent of the Superior and Rainey glacial lobes as they flowed side by side as a single lobe and then terminated to form the St. Croix Moraine. As the glacier retreated and melted, it left behind areas of outwash and till deposit formations. The area of outwash formations that is located in the western portion of the city is comprised of silt, sand, and gravel that were carried, sorted, and deposited by glacial melt-water. The area of till formations located in the eastern two-thirds of the city is composed of unsorted clay, silt, sand, and boulders transported and deposited by glacial ice. Silt and sand lenses are interspersed throughout this formation. The original terrain and vegetation of the area were mainly altered for purposes of farming when the area was first settled. Marshes and wetlands were left relatively undisturbed except for a few ditching projects. More detailed information on the drainage system of the city can be found in the city’s 2018 Surface Water Management Plan (SWMP) Appendix I. 10 Chapter 7 - Natural Resources City of Mendota Heights 2040 Comprehensive Plan Update Soils The Soil Conservation Service has identified the following soil associations within the City of Mendota Heights: •Nearly Level Soils on the Floodplains. This area is on the floodplains of the Minnesota and Mississippi Rivers, mostly located in the Fort Snelling State Park. The area consists of mixed Alluvial sand and some Sawmill soils. Colo soils, Riverwash, and Peat Muck are also present. •Light Colored, Rolling to Hilly Soils. This general area is in the Morainic part of the County. It is characterized by steep slopes and numerous poorly drained depressions. The soils are extremely variable in depth, texture, and productivity. The major soils include Scandia Kingsley, Hayden, and Burnsville series. Included are soils of the Freer and Adolph series. •Light Colored to Moderately Dark Colored, Rolling to Loose Hilly Soils on Till. In topography and texture, this soil association is mostly the light colored rolling high soils described above. Most of the soils develop from calcareous materials. The major soils in the area include the Hayden, Burnsville, Lester series. 11 MENDOTA LILYDALE PICKEREL LAKEMISSISSIPPI RIVERMINNESO T A RI V E R ROGERS LAKELAKE AUGUSTA LA K E L EMA Y GUN CLUB LAKE DODD RDDODD RDDELAWARE AVESIBLEY MEMORIAL HWYMARIE AVE W MENDOTA HEIGHTS RDLEXINGTON AVELILYDALE RDPILOT KNOB RDHUBER DR SI BLEYMEMORIALNORTHLAND DR WENTWORTH AVE WWACHTLER AVEWAGON WHEEL TRL MENDOTA RDHUNTER LNORCHARD PL VICTORIA RD SIVY FALLS AVE Topography Mapµ0 3,000 6,000 Feet 50' Contour Lines Elevation up to 700' Elevation 700' - 750' Elevation 750' - 800' Elevation 800' - 850' Elevation 850' - 900' Elevation 900' - 950' Elevation 950' - 1,000' Elevation above 1,000' City Boundary Land Parcel Line Open Water City of Mendota Heights Source: City of Mendota Heights, Dakota County, 2016 June 2019 FIGURE 7-1 Map 7-1.

They provide a variety of benefits and functions including filtering stormwater pollutants, providing flood protection and storage, and providing wildlife habitat and recreational enjoyment. The city contains many wetland areas that vary in quality. Most are impacted by stormwater runoff, with some receiving direct input from storm pipes. Wetland areas are protected under the Minnesota Wetland Conservation Act (WCA) and Minnesota Rule 8420. The City Council is also the Local Government Unit for Mendota Heights, and is responsible for administrating the Wetland Conservation Act (WCA) within the city. In accordance with State Rules and the Minnesota WCA, the city has adopted and maintained a Wetlands Systems Ordinance under City Code Title 12-2-1 and provides for Wetland Protection under City Code Title 14-1-9, all of which help ensure the preservation and enhancement of the functions and values of its wetlands. It is anticipated that the Wetland Management Plan, through wetland inventorying, will provide a planning tool for the city to use for future projects that may affect wetlands. The inventory of wetlands will allow the city to identify restoration areas within public lands, enhance wetland value for wildlife, provide and enhance recreational values of wetlands, designate wetland restoration or enhancement opportunities, protect wetlands and adjacent resources that provide valuable ecological support, and provide stormwater protection. The city is also an active participant in the Wetland Health Evaluation Program (WHEP), which engages citizens in evaluating and monitoring the health of wetland areas throughout the city. Map 7-2. Wetlands is also included as part of the city’s 2018 Surface Water Management Plan (SWMP). More detailed information on the city’s wetlands can be found in the 2018 SWMP, included as Appendix I. Floodplain Although the City of Mendota Heights is located in close proximity to the Mississippi River and the Minnesota River, floodplain does not exist within developed areas of the city. As the Floodplain map portrays, there is floodplain on both sides of the Mississippi River and Minnesota River, within the cities of St. Paul, Lilydale, Mendota, and Eagan. This floodplain makes up the majority of the northwest boundary of the city. 17 Map 7-2. Wetlands 18 Chapter 7 - Natural Resources City of Mendota Heights 2040 Comprehensive Plan Update Watersheds Mendota Heights is part of two watersheds: The Lower Mississippi and Lower Minnesota River watersheds, which are illustrated on Map 7-3. Hydrography. The Lower Mississippi River Watershed Management Organization (LMRWMO) encompasses 50 square miles in Dakota and Ramsey Counties. Other surrounding communities include: Inver Grove Heights, Lilydale, St. Paul, South St. Paul, Sunfish Lake, and West St. Paul. The LMRWMO was established by a Joint Powers Agreement in 1985. The watershed contains well-drained soils with many small depressions and steep slopes. Issues of concern include water quality, erosion control, wildlife habitat and water recreation. The Lower Minnesota River Watershed District (LMRWD) is located in the southwest part of the Twin Cities metropolitan area along the Minnesota River. The district boundaries encompass an area of 64 square miles of Carver, Hennepin, Dakota, Scott, and Ramsey counties, which includes the Minnesota River Valley from Fort Snelling, at the confluence of the Minnesota and Mississippi rivers, upstream to Carver, Minnesota. The width of the district includes the bluffs on both sides of the Minnesota River within this reach of the river. The City of Mendota Heights entered into an agreement with the Lower Minnesota River Watershed District in 2005. Issues of concern include dredging, spoil site acquisition, and bank erosion control. Significant Vegetation The City of Mendota Heights contains a wide variety of forested areas including a large amount of floodplain forest along the Mississippi and Minnesota Rivers. There is a large area of altered, non-native deciduous forest on the east side of Gun Club Lake. Map 7-4. Significant Vegetation illustrates the location of wooded and forested areas throughout the city. A Minnesota Land Cover Classification System (MLCCS) search was performed for the areas below the bluffs. The bluffs themselves are upland areas. The MLCCS Summary Table 1 (City of Mendota Heights 2018 SWMP, Section 2.6) provides a list of the land cover types below the bluffs and the area of each type that falls within the Mendota Heights city limits. Of special note is the presence of a calcareous seepage fen prairie.

The east side of 35E within the City of Mendota Heights, just before entering Lilydale, contains a variety of vegetation, from altered/non-native deciduous forest, altered/non-native deciduous woodland, altered/non-native mixed woodland, oak forest, floodplain forest, and lowland hardwood forest. There are also pockets of a variety of forests and woodlands between 35E and the boundary with West St. Paul and Sunfish Lake, especially surrounding the water features. Site Classifications and Natural Resources Issues Natural areas abound in Mendota Heights on public as well as on private lands. The city manages natural resources at both the site level and by broad, city-wide natural resource issues, through city policies and ordinances, collaboration with other agencies and citizen groups, and the use of adopted plans and guidance documents. Parks and Trails Some of Mendota Heights’ Parks have areas of woodland or naturalized landscapes. Park natural areas with high ecological quality should be prioritized and actively managed. Open Spaces There are many other city-owned natural areas that are not part of Mendota Heights’ Park System. Many of these contain wetlands or steep slopes. Some have high quality oak woodlands. Open spaces provide habitat, natural resource connections, stormwater management, and visual interest. Some open space sites have moderate to high ecological quality and should be inventoried and identified on an ecological overlay as part of the city GIS mapping and asset inventory. Active management is needed to sustain these high quality resources. 23 Chapter 7 - Natural Resources City of Mendota Heights 2040 Comprehensive Plan Update City-wide Natural Resources Issues and Natural Resources Trees and Urban Forest Mendota Heights’ urban forest includes boulevard trees, park trees, woodlands, and trees on private property. The city’s forestry program includes: trimming and removal of trees on city property, tree planting on city property, diseased tree inspection and management when feasible, and education and outreach. In 2017, Emerald Ash Borer was documented for the first time in Mendota Heights. The city began ash tree removals on city property in December 2017, and will continue management into the future. The city anticipates it will lose most of its ash trees to this invasive insect. Given the proximity of Mendota Heights to the Mississippi and Minnesota Rivers and accompanying tree-lined bluffs, the city has an opportunity and responsibility to protect and enhance native species of trees in the city. The management, removal, and replacement of invasive trees and shrubs with native species helps sustain the city’s natural resources, the river bluffs, critical areas, ecological communities, as well as quality of life for the community. Urban Wildlife Large areas of contiguous habitat are needed for healthy, diverse wildlife. The city’s approach to wildlife management is on providing habitat for wildlife. While the city does not manage for particular species, it does strive to manage for and increase native plant diversity to provide higher quality habitat for native pollinators. The city became a Pollinator Friendly City in 2016 (see Resolution 2016-01, adopted January 5, 2016 and Pollinator Friendly Native Plantings List – Appendix E).

Controlling invasive vegetation before it becomes widespread is more effective and less costly than managing it after widespread establishment. The city is committed to control or eradicate invasive species on the State Noxious Weed list. Surface Water Quality The city has a diverse collection of surface water resources within its boundaries including lakes, streams, rivers, and wetlands. Protecting these resources requires ensuring that the storm water that enters these surface waters does not degrade, or further degrade, the health of the city’s surface water resources and the aesthetic, ecological, and recreational benefit they provide. The city utilizes a variety of strategies to monitor and protect its surface water resources including: •Collaboration with other government agencies, community groups, and citizens to help monitor and protect these resources. •The city uses its current Surface Water Management Plan (SWMP) as a guide to conserve, protect, and manage the city’s surface water resources. •The City of Mendota Heights holds a required National Pollution Detection and Elimination System (NPDES Phase II) Municipal Separate Storm Sewer System (MS4) permit (see the SWMP, within the Appendix) with the Minnesota Pollution Control Agency, that includes an evaluation of the city’s stormwater system, and a Surface Water Pollution Prevention Plan (SWPPP), that identifies Best Management Practices, goals, and actions for implementation. •The city works in conjunction with Watershed Districts, Watershed Management Organizations, and other government agencies to establish strategies for addressing its impaired waters. Surface waters are designated as impaired if they do not meet State standards for their designated use due to a specific pollutant or stressor. Impaired Waters within Mendota Heights include the Minnesota River, Interstate Valley Creek, and Lake Augusta. 26 Chapter 7 - Natural Resources City of Mendota Heights 2040 Comprehensive Plan Update •The city also has adopted water resources management ordinances and policies that include Title 14, Chapter 1 of City Code: Stormwater Management, Illicit Discharge, Soil Erosion, and Sedimentation, which establishes standards and specifications for conservation practices and planning activities to protect and enhance water quality. Issues & Opportunities The City of Mendota Heights finds it critical to prioritize projects to protect and manage the most important sites to make the best use of funding and staff time. The science of managing natural systems continues to evolve. The city will continue to cultivate strong partnerships with other agencies, non-profits, and citizen groups to seek expertise in the management of its natural resources. Additionally, the city will strive to educate residents on environmental issues and foster stewardship and volunteerism. Grants for enhancing natural areas that are available through State, County, and other agencies should be vetted on an ongoing basis by city staff. The city should inventory and track natural resource assets such as open space sites, public trees, and permanent stormwater Best Management Practices (BMPs). This will provide an opportunity to better manage these resources. The city should also manage all of its surface water resources using scientifically based, common sense approaches that meet or exceed regional, state, and federal regulatory requirements. CITY OF MENDOTA HEIGHTS 2040 Comprehensive Plan Update Chapter 8: Resilience This page is intentionally blank. 1 Chapter 8 - Resilience City of Mendota Heights 2040 Comprehensive Plan Update 8 RESILIENCE Resilience can be defined as the ability to recover from difficulties – the ability to return to a sense of normalcy. Preventing disasters is the first priority but responding effectively to disasters is also essential to be resilient. Between 2012 and 2018 alone, Mendota Heights faced three serious emergencies, two of which were weather-related, the other infrastructure related. To be resilient Mendota Heights needs to anticipate disasters and be ready to respond to catastrophic events. In the wake of climate change, our community’s resiliency will likely be challenged, since extreme weather is likely to continue with increased frequency. This chapter outlines reactive strategies for handling emergency services in the event of disaster as well as proactive strategies for mitigating the effects of climate change. The world’s climate is changing, and the growing frequency and large-scale impact of severe weather events demonstrates the importance of building a foundation of resilient systems to meet ordinary and extraordinary circumstances. Resilience is not a required element for the 2040 Comprehensive Plans in the region, but Mendota Heights is committed to investing in resilience. Supporting resiliency strategies will protect local and regional vitality for future generations by preserving our capacity to maintain and support our region’s well-being and productivity. Considerations of vulnerabilities in resilience strategies, and response to those vulnerabilities, will strengthen community preparedness and response to climate impacts. The Resilience update for Mendota Heights primarily focuses on goals and policies related to: -Hazard mitigation and emergency response; -Climate action; -Resilient energy; and -Resilient food systems. Additional chapters within the Mendota Heights 2040 plan also contribute to building resilience in Mendota Heights, which include Land Use; Natural Resources; Parks and Trails; Transportation; and Economic Development. 2 Chapter 8 - Resilience City of Mendota Heights 2040 Comprehensive Plan Update Hazard Mitigation & Emergency Response Dakota County Hazard Mitigation Plan In 2016, Dakota County developed an All-Hazard Mitigation Plan. This plan incorporated numerous cities and townships in Dakota County and was developed to identify and prepare for a variety of hazards such as flooding or tornadoes before they occur. The purpose of the plan is to reduce the loss of lives and property damage in the event of a hazard occurring in the area. The All-Hazard Mitigation Plan includes a list of goals, objectives and strategies for the county to better prepare and coordinate efforts for disasters. The goals of the plan include: -Reduce Hazard Risks and Impacts; -Build on Existing Efforts; and -Share Information and Raise Awareness. This plan serves as a framework for managing public and private investment in the face of a changing climate and more severe storm events. Mendota Heights Emergency Operation Plan The Emergency Operations Plan (EOP) was written to ensure a coordinated, effective response by elected officials and city staff to disasters that create significant disruption and stress to community resources. The plan was written per state and federal law to describe proper management of a given emergency or disaster. The purpose of the plan is to: -Maximize the protection of life and property; -Stabilize incidents; -Effectively respond to an emergency or disaster; -Ensure the continuity of government and continuity of services; and -Provide recovery and restoration of services This framework is intended to account for resources and procedures that will allow for the effective response to an emergency or disaster. 3 Chapter 8 - Resilience City of Mendota Heights 2040 Comprehensive Plan Update Climate Action Minnesota, Dakota County, and the City of Mendota Heights are already experiencing the impacts of a changing climate. Climate trends suggest that in the next 50 years we will experience increased precipitation, hotter summers, warmer and wetter winters, and more severe weather events. These changes can damage infrastructure, disrupt essential services, drain resources and impact a city’s capacity to respond to citizen’s needs. These climate changes are also expected to have substantial impacts on public health and emergency responders as a result. Direct impacts include increases in injuries and deaths attributed to extreme heat events, extreme weather events (e.g., floods), air pollution, and vector-borne and other infectious diseases (see Figure 8-1). Climate resilient communities can prevent the worst public health and economic impacts of climate change by effectively adapting the built environment to climate change and reducing greenhouse gas emissions to mitigate the impacts of climate change. Many of the solutions to reducing impacts are already a part of our municipal government expertise. In many instances, responding to climate change does not require large scale changes to municipal operations, but simply requires adapting existing plans and polices to incorporate knowledge about changing Figure 8-1.

Strategies which strengthen resilience in time of emergency also help communities thrive even more during good times. Population Vulnerability Assessment & Climate Adaptation Framework A Population Vulnerability Assessment and Climate Adaptation Framework may seek to: •Increase awareness of potential climate impacts and population vulnerabilities; •Increase inclusion of climate adaptation dialogue within city planning and decision making processes; •Strengthen adaptive capacity based on the best available information on regional climate change projections and impacts; •Outline priority risks, vulnerabilities, and possible near-term actions; •Lay the foundation for the development of implementation plans that consider available resources and prioritize the most effective actions from a cost and benefit perspective; and •Prevent or reduce the risks to populations most vulnerable to the impacts of climate change. A Population Vulnerability Assessment describes how climate affects the community and region of today, and the changes and impacts expected over the coming decades, and includes identifiers of population vulnerabilities. A Climate Adaptation Framework provides recommended Adaptation Goals as well as a menu of Adaptation Strategies. The city can enact these climate resilience goals and strategies to reduce the impact of climate change, improve public health, and expand the local economy. Across all of these goals, there are four priority areas of action. 1.Assess vulnerabilities - e specially among populations most vulnerable to climate change impacts. 2. Train and educate local officials, planners, and community organizations 5 Chapter 8 - Resilience City of Mendota Heights 2040 Comprehensive Plan Update 3.Incorporate climate vulnerabilities into existing planning documents. 4. Develop partnerships to fund on-going research and implementation. GOALS & POLICIES – Hazard Mitigation & Climate Action GOAL 1: Protect and maintain infrastructure and constructed systems that provide critical services. Policies 1.Assess public buildings and sites for vulnerabilities to extreme weather and make improvements to reduce or prevent damage and sustain function. Increase the resilience of natural and built environment to more intense rain events and associated flooding. 2.Improve the reliability of back-up energy for critical infrastructure. Support well- planned improvements to the private utility and communications networks that provide efficiency, security and needed redundancy. 3.Continue to explore and incorporate new and emerging technologies to construct, rehabilitate, maintain and manage public assets and infrastructure in an efficient, cost effective manner. 4.Support the efforts of residents and businesses to plant and install new trees in areas with low coverage, areas with high heat vulnerability, or areas exposed to more vehicle exhaust. 6 Chapter 8 - Resilience City of Mendota Heights 2040 Comprehensive Plan Update GOAL 2: Proactively maintain public health and safety during extreme weather and climate-related and other unforeseen events. Policies 1.Continue to work with Dakota County in updating the All- Hazard Mitigation Plan and partner to ensure essential needs of all residents are met during an emergency. 2. Investigate funding opportunities to support the city’s resilience efforts. 3.Consider conducting a Population Vulnerability Assessment and Climate Adaptation Framework plan to outline priority vulnerabilities and identify available resources to strengthen community capacity to respond. 4.Designate appropriate facilities that will be made available to the public as community safe shelters and arrange for adequate provisions and backup power. 5.Coordinate with emergency dispatch and first responders to address the specific concerns of residents who may be more vulnerable in each type of event. GOAL 3: Promote social connectedness and build an engaged community of resilience. Policies 1.Strengthen working relationships with community organizations to support the most at-risk residents. 2. Promote education and outreach with the community on the health impacts and risk mitigation of air pollution, longer allergy seasons, extreme heat, water quality changes, and vector-borne disease. 3. Promote and report on the city’s sustainability and resilience projects and initiatives. 4. Review ordinances with respect to recreational fires and particulate emissions and update as needed to protect and maintain healthy air quality. 5. Review emergency communications procedures to ensure the public is adequately informed in the event of an emergency. Develop a communications plan for the residents to inform them in the event of an emergency. 7 Chapter 8 - Resilience City of Mendota Heights 2040 Comprehensive Plan Update Resilient Energy Local renewable energy resources are abundant and readily available for economic capture. Renewable energy resources currently available in Mendota Heights include solar, with the potential to incorporate wind, biomass, geothermal, and efficiency resources (e.g. building improvements for energy efficiency). All of these resources should be evaluated for use at residential, private and community scale. Mendota Heights desires to set goals and policies that treat sustainable local energy resources as an economically valuable local resource. Strategies to reduce energy consumption including alternative modes of transportation must be initiated. Renewable Energy Efforts in Mendota Heights The City of Mendota Heights is committed to a resilient future, including promoting renewable energy where feasible. The city has existing code language supporting residential rooftop and ground-mounted solar development throughout the community. Although solar energy systems are allowed in all zoning districts, systems must be accessory to the primary land use. Large- scale commercial solar farms or gardens are not currently allowed in Mendota Heights. The ordinance also addresses building-integrated solar systems and passive solar energy systems. As stated in the goals for this chapter and emphasized in the code of ordinances, Mendota Heights supports the development of solar energy systems that result in a net gain in energy and do not have negative impacts on surrounding uses and surrounding solar access. This Plan also includes information on gross solar resources to provide data context to these recommendations. 8 Chapter 8 - Resilience City of Mendota Heights 2040 Comprehensive Plan Update Gross and Rooftop Solar Resources The Metropolitan Council has calculated the gross and rooftop solar potential for the City of Mendota Heights to identify how much electricity could be generated using existing technology. The gross solar potential and gross solar rooftop potential are expressed in megawatt hours per year (Mwh/yr), and these estimates are provided in Table 8-1. Gross and Rooftop Solar Potential: Table 8-1. Gross and Rooftop Solar Potential Community1 Gross Potential (Mwh/yr) Rooftop Potential (Mwh/yr) Gross Generation Potential (Mwh/yr)22 Rooftop Generation Potential (Mwh/yr)2 Mendota Heights 12,356,007 945,566 1,235,600 94,556 Source: Metropolitan Council Developed areas with low building heights and open space areas have the highest potential for solar development in the city. Many of the developed neighborhoods and some natural areas in Mendota Heights do not have high gross solar potential due to existing tree cover. This gross development potential is illustrated on Map 8-1. Gross Solar Potential. 1. There are a few communities where generation potential calculations could not be produced. There are areas within some maps where data was unusable. These areas were masked and excluded from gross rooftop potential and generating potential calculations. 2. In general, a conservative assumption for panel generation is to use 10% efficiency for conversion of total isolation into electric generation. These solar resource calculations provide an approximation of each community’s solar resource. This baseline information can provide the opportunity for a more extensive, community-specific analysis of solar development potential for both solar gardens and rooftop or accessory use installations. For most communities, the rooftop generation potential is equivalent to between 30% and 60% of the community’s total electric energy consumption. The rooftop generation potential does not consider ownership, financial barriers, or building-specific limitations. 9 Chapter 8 - Resilience City of Mendota Heights 2040 Comprehensive Plan Update 35E Mendota Heights DODD RDWENTWORTH AVE W HIGHWAY 110 MENDOTA HEIGHTS RDLEXINGTON AVE SONEILL RD DELAWARE AVEPILOT KNOB RDHIGHWAY 13MARIE AVE W 55 55 62 High : 1276135 Low : 900001 Solar Potential under 900,000 watt-hours per year County Boundaries City and Township Boundaries Wetlands and Open Water Features Gross Solar Potential Source: University of Minnesota U-Spatial Statewide Solar Raster.

Policies 1.Regularly review renewable energy policies and programs, including the alternative energy systems ordinance (§12-1D-18). 2.Support mass transit goals as detailed in Transportation Section 3. 3.Prioritize infrastructure improvements that support walking and biking as an integral part of the transportation system. Resilient Food System The well-being of our residents is vital to long-term sustainability and prosperity of our community. Local planning policies can reduce or reinforce structural barriers that prevent our food supply from being as healthy, equitable, affordable, and resilient as we would like it to be. By prioritizing policy initiatives at a local level that support a robust food infrastructure, Mendota Heights can help improve the quality of life for its residents and leave a legacy of health for future generations. Small Scale Food Production in Mendota Heights The City of Mendota Heights has an opportunity to build from established food system policy efforts, currently including: •Keeping Chickens: The city permits residents to keep up to six female chickens for individual egg production (§12- 1D-3). The city’s code specifies coop and run requirements as well as guidance on proper care and the permitting process for domestic chickens on residential lots. •Farming Operations: Existing farms are permitted in the city, with the exception of animal farming (§12-1D-8). Farmers may also sell products produced at an on-site farm stand. 13 Chapter 8 - Resilience City of Mendota Heights 2040 Comprehensive Plan Update •Beekeeping: The City of Mendota Heights allows for the keeping of honey bees on parcels of 50-acres or more in the R-1 Residential Zone (Sect. 12-1E-3C). The acreage limitation was established to minimize the impact honey bees may have on native bees by outcompeting them for food resources, and transmitting diseases to native bees. Access to Food Markets There are no grocery stores or supermarkets within the City of Mendota Heights. Although such markets exist in neighboring municipalities, access to those stores is largely dependent on the automobile. As the population ages, access via automobile may become problematic. An important consideration should be that the city supports local food markets. Disposal of Food Waste and Organic Recycling The City of Mendota Heights participates in Dakota County’s curb-side recycling program and residents can opt-in to participating in the County’s organics drop off program in West St. Paul. Businesses are also eligible to participate in recycling programs with the County to further reduce waste in the city. As technology advances, the city will study the feasibility of introducing curb-side organic recycling programs as has been done in other municipalities in efforts to reduce waste. 14 Chapter 8 - Resilience City of Mendota Heights 2040 Comprehensive Plan Update GOALS & POLICIES – Resilient Food System GOAL 7: Explore opportunities to support land use guiding and regulations that support practices that integrate healthy food production in residential settings and support food-related businesses and activities. Policies 1.Support the development of a Mendota Heights Farmers Market as an accessible and reliable source for local, healthy food. 2.Support innovative local food production solutions such as aquaponics, hydroponics, indoor agriculture, backyard gardening and composting, community gardens, and urban farming, where appropriate. 3.Encourage edible and pollinator-friendly landscapes on residential properties. 4.Support innovative practices such as mobile food markets and mobile food pantries/food shelves that can bring food closer to elderly and other under- resourced residents. GOAL 8: Promote responsible waste disposal and study feasibility of improving systems that encourage residents to make responsible decisions. 1.Promote use of County Organics drop-off station. 2.Study feasibility of organics pick-up in the years to come as technology advances and is more readily available. 3.Educate on and support back-yard composting in efforts to reduce waste. CITY OF MENDOTA HEIGHTS 2040 Comprehensive Plan Update Chapter 9: Mississippi River Corridor Critical Area This page is intentionally blank. 1 Chapter 9 - MRCCA City of Mendota Heights 2040 Comprehensive Plan Update 9 MISSISSIPPI RIVER CORRIDOR CRITICAL AREA Pursuant to the Critical Areas Act of 1973 and Executive Orders in the 1970s, the State of Minnesota established the Mississippi River Corridor Critical Area Plan (MRCCA) to protect and preserve the natural, scenic, recreational, and transportation resources of Mississippi River as it travels through the Twin Cities. The MRCCA covers a 72-mile stretch of the Mississippi River through the Twin Cities Metropolitan Area, comprising 54,000 acres of land in 30 local jurisdictions from Dayton in the north to Hastings in the south. The purpose of the MRCCA is to: •Protect and preserve the Mississippi River and adjacent lands that the legislature finds to be unique and valuable state and regional resources for the benefit of the health, safety, and welfare of the citizens of the state, region, and nation; •Prevent and/or mitigate irreversible damages to these state, regional, and national resources; •Preserve and enhance the natural, aesthetic, cultural, and historical values of the Mississippi River and adjacent lands for public use and benefit; •Protect and preserve the Mississippi River as an essential element in the national, state, and regional transportation, sewer and water, and recreational systems; and •Protect and preserve the biological and ecological functions of the Mississippi River Corridor. 2 Chapter 9 - MRCCA City of Mendota Heights 2040 Comprehensive Plan Update The MRCCA is important because of its many significant natural and cultural resources, including scenic views, water, navigation, geology, soils, vegetation, minerals, fauna, cultural resources, and recreational resources. The MRCCA is home to a full range of residential neighborhoods and parks, as well as river-related commerce, industry, and transportation facilities. In 2016, the Minnesota Department of Natural Resources (MnDNR) revised the rules and regulations governing development within the MRCCA which have been incorporated into this Plan and will be incorporated into the city’s zoning ordinance after Plan approval. Local communities within the Corridor are required to complete a MRCCA plan as a chapter of their Comprehensive Plan update for this Planning Period. The rules also require local governments to update their MRCCA plans and their MRCCA ordinances, if they exist, or create both the plan and supporting ordinances consistent with the rules. MRCCA in Mendota Heights The City of Mendota Heights accepts that the Mississippi River Corridor exists within the metropolitan area and the city is a unique and valuable local, state, regional and national resource. The river is an essential element in the local, regional, state and national transportation, sewer and water, and recreational systems and serves important biological and ecological functions. The prevention and mitigation of irreversible damage to this resource and the preservation and enhancement of its natural, aesthetic, cultural and historic values is in furtherance of the health, safety and general welfare of the city. Since it is a new rule that the MRCCA chapter be incorporated into the Plan, the City of Mendota Heights must create both the chapter and a supporting ordinance to implement the information contained herein. The goals stated within this chapter are new, and prior to this planning process no specific plans or goals were formally adopted by the city. The city did have a reference to the MRCCA/MNRRA which identified the Critical Area Overlay and enforced a corresponding ordinance which provided regulations for all new developments within the overlay area. The city will incorporate applicable sections from the existing ordinance into the updated ordinance, which will be developed to implement this MRCCA chapter. Generally, the boundaries of the MRCCA in Mendota Heights are situated along the Mississippi River Corridor, starting at Fort Snelling State Park / Interstate 494 to the south and extends northwesterly along this natural corridor and Sibley Memorial Highway (State Highway 13) for approximately 5 miles, and to the northerly boundary line of the city at Annapolis Street (See Map 9-1 and Map 9-2). The MRCCA boundary fluctuates in width along this corridor from one-tenth (1/10) to one-third (1/3) of mile in width in areas. Much of this land is used for single-family residential purposes or public park land. 3CA-UMCA-UMCA-RNCA-ROSCA-UMCA-ROSCA-ROSCA-UMCA-ROSCA-SRCA-SRCA-RNCA-RNCA-RTCCA-RNCA-RNCA-RNCA-SRCA-RTCCA-UCCA-RTCCA-RNSaint PaulMendota HeightsNewportSouth Saint PaulLilydaleMendotaMaplewoodInver Grove HeightsMississippi River Corridor Critical Area (MRCCA) District Map - St. PaulMinnesota Rules, part 6106.0100´00.510.25MilesCA-RN: River NeighborhoodCA-SR: Separated from RiverCA-UM: Urban MixedCA-UC: Urban CoreMRCCA Districts(Effective January 4, 2017)CA-ROS: Rural & Open SpaceCA-RTC: River Towns & CrossingsWaterMunicipal BoundariesMRCCA BoundaryTextFIGURE9-1June 2019Source: Metropolitan CouncilMap 9-1.

These districts are characterized by the various natural and built features of the river corridor. Most standards and requirements outlined in the rules apply uniformly throughout the corridor. However, certain requirements such as structure setbacks, bluff standards, building height limits, additional subdivision standards, and the amount of open space required for development vary by district. There are three (3) MRCCA districts present in Mendota Heights. 1. Rural & Open Space District (CA-ROS): Rural and Open Space District (CA-ROS): The CA-ROS district is characterized by rural low density development patterns and land uses, and includes land that is riparian or visible from the river, as well as large, undeveloped tracts of high ecological value, floodplain, and undeveloped islands. Many primary conservation areas exist in this district. The “rural and open space” district has the lowest level of development of all of the proposed districts within the MRCCA. To preserve the rural and open space characteristics of this district and its unique recreational value, a structure height limit of 35-feet is proposed for this district. This district includes agricultural and rural residential areas, parkland and natural areas adjacent to the river. This height is intended to keep structures at or below the level of the tree line and is consistent with height restrictions in most of the local zoning standards that apply in these areas The CA-ROS district must be managed to sustain and restore the rural and natural character of the Corridor, and to protect and enhance existing habitat, public river corridor views, and scenic, natural and historic areas. In Mendota Heights, the CA-ROS district encompasses primarily the Fort Snelling State Park area (including Gun Club Lake) and a small area of Lilydale/Harriet Island/Cherokee Park property located on the north side of Hwy. 13, between Wachtler Avenue and Sylvandale Road. These districts comprise approximately 591.5 acres of vacant, open and natural land areas. 6 Chapter 9 - MRCCA City of Mendota Heights 2040 Comprehensive Plan Update 2. River Neighborhood District (CA-RN): River Neighborhood District (CA-RN): The CA-RN district is characterized by residential neighborhoods that are riparian or readily visible from the river or that abut riparian parkland. The district includes land separated from the river by distance, topography, development, or a transportation corridor. The land in this district is not readily visible from the Mississippi River. The MnDNR Statement of Need and Reasonableness (SONAR) outlines height limits for the CA-RN District, which is a 35-foot height limit for all residential “river neighborhood” districts. The height limit is intended to allow a typical two-story single-family dwelling that does not break the top of the tree line. This height restriction is consistent with existing structure heights in residentially zoned neighborhoods and height restrictions in most of the local zoning standards that apply in these areas. The City of Mendota Heights intends to preserve and maintain a 25- foot height (maximum) standard for all single-family dwellings as currently regulated in the city’s Zoning Ordinance, or the adopted height standards for any underlying zoning district inside the CA-RN district. The CA-RN district must be managed to maintain the character of the river corridor within the context of existing residential development, and to protect and enhance habitat, parks and open space, public river corridor views, and scenic, natural, and historic areas. Minimizing erosion and the flow of untreated stormwater into the river and enhancing shoreline habitat are priorities in this district. In Mendota Heights, the CA-RN district encompasses approximately 256 acres of area. 3. Separated from River District (CA-SR) Separated from River District (CA-SR): This district includes non-riparian land that is separated from the Mississippi River by distance, development, or transportation infrastructure. Because of this separation, underlying zoning standards govern height, with the stipulation that structure height must be compatible with the existing tree line, where present, and surrounding development. The MnDNR Statement of Need and Reasonableness (SONAR) further describes height restrictions for the CA-SR District. The “separated from river” district includes non-riparian land that is separated from the Mississippi River by distance, development, or transportation infrastructure. Because of this separation, underlying zoning standards govern height, with the stipulation that structure height must be compatible 7 Chapter 9 - MRCCA City of Mendota Heights 2040 Comprehensive Plan Update with the existing tree line, where present, and surrounding development. The City of Mendota Heights intends to preserve and maintain a 25-foot height (maximum) standard for all single- family dwellings as currently regulated in the city’s Zoning Ordinance, or the adopted height standards for any underlying zoning district inside the CA-SR district. The CA-SR district provides flexibility in managing development without negatively affecting the key resources and features of the river corridor. Minimizing negative impacts to primary conservation areas and minimizing erosion and flow of untreated storm water into the Mississippi River are priorities in the district. MRCCA with Future Land Use & Zoning The planned land uses within the MRCCA districts in Mendota Heights are a mix of existing and planned low-density residential areas; small segments of existing and planned medium-density residential areas; a small limited business area; and a large public recreation/open space area in and around Fort Snelling Park/Gun Club Lake. As part of their comprehensive planning process, the City of Mendota Heights has developed a 2040 Future Land Use Plan. The map illustrates planned land uses including single and multi-family residential, commercial, public and open space area. Most of the city area inside the MRCCA boundary is predominantly developed with single-family housing, though there are small commercial and mixed-use areas along the Highway 13 (Sibley Memorial Highway) and near the Highway 13/I-35E interchange. Most of the Park and Open Space areas include the Fort Snelling State Park and Lilydale/Harriet Island Regional Park, and other lands along the Mississippi River. These planned future land uses correspond appropriately to the districts that the Minnesota Department of Natural Resources (MnDNR) has developed. Future land uses in each of these districts are listed as follows. Rural and Open Space District CA-ROS: Future land uses include parks and open spaces. River Neighborhood District CA-RN: Future land uses include single-family, multi-family, and parks and open spaces. Separated from River District CA-SR: There are some parcels in the MRCCA district with planned future land uses of single-family and a very limited number of multi-family residential uses. 8 MENDOTA LILYDALE PICKEREL LAKEMISSISSIPPI RIVERMINNESO T A RI V E R ROGERS LAKELAKE AUGUSTA LA K E L EMA Y GUN CLUB LAKE DODD RDDODD RDDELAWARE AVESIBLEY MEMORIAL HWYMARIE AVE W MENDOTA HEIGHTS RDLEXINGTON AVELILYDALE RDPILOT KNOB RDHUBER DR SI BLEYMEMORIALNORTHLAND DR WENTWORTH AVE WWACHTLER AVEWAGON WHEEL TRL MENDOTA RDHUNTER LNORCHARD PL VICTORIA RD SIVY FALLS AVE MRCCA Boundary with 2040 Future Land Use Map City of Mendota Heights µ0 3,000 6,000 Feet Mississippi River Critical Area Layer RR - Rural Residential LR - Low Density Residential MR - Medium Density Residential HR - High Density Residential LB - Limited Business B - Business MU - Mixed Use I - Industrial P/S - Public/Semi-Public P - Park & Open Space Open Water Map 9-3.

MRCCA Boundary with 2040 Future Land Use Plan. As an implementation step of this Plan, the city will fully evaluate its preferred dimensional requirements for the property for any new developments and redevelopment of lands, and will work with the MnDNR on proper steps to incorporate flexibility within the MRCCA ordinance to address this particular area. Most of the properties located in this MRCCA boundary are planned and guided for low-density residential uses, which are primarily developed with single-family uses. The city will work with property owners through the MRCCA ordinance preparation process to understand existing conditions of the property within the CA-RN and CA-SR districts, and identify any potential conflicts with the existing standards and how to address non-conforming uses within the district.

Policies 1.Adopt a new MRCCA ordinance overlay district compliant with the goals and policies of the MRCCA plan, and with Minnesota Rules, part 6106.0070, Subp. 5 - Content of Ordinances; and work collaboratively with the MnDNR to address flexibility with the ordinance, if needed, and as noted in previous sections of this Plan. 2.Update zoning map to include new MRCCA overlay districts. 3.Ensure that information on the new MRCCA districts and zoning requirements is readily available to property owners to help them understand which ordinance requirements - such as setbacks and height requirements - apply to their property for project planning and permitting. 4.Work with the MnDNR on height standards to determine appropriate height restrictions, particularly on redevelopment areas with existing site constraints. PRIMARY CONSERVATION AREAS (PCA) General Overview As the MnDNR’s Statement of Needs and Reasonableness (SONAR) defines it, the term “primary conservation areas” (PCAs) addresses the key natural and cultural resources and features managed by MRCCA rules. These features are given priority consideration for protection with regard to proposed land development, subdivision, and related activity. PCAs include Shore Impact Zones (SIZ), Bluff Impact Zones (BIZ), floodplains, wetlands, gorges, areas of confluence with tributaries, natural drainage routes, unstable soils and bedrock, native plant communities, cultural and historic properties, significant existing vegetative stands, tree canopies and “other resources” identified in local government MRCCA plans. 11 Chapter 9 - MRCCA City of Mendota Heights 2040 Comprehensive Plan Update Shore Impact Zone Shore Impact Zones (SIZs) apply to the Mississippi and all of its backwaters, as well as to its four key tributaries, including the Crow, Rum, Minnesota, and Vermillion rivers. They include land along the river’s edge deemed to be environmentally sensitive and in need of special protection from development and vegetation removal. A typical shore impact zone (SIZ) is a “buffer” area that is required between the water’s edge and the area where development is permitted (see Figure 9-1); and is the focus of many of the MRCCA rule standards for land alteration and vegetation management. Mendota Height’s zoning map and the related Critical Corridor Area map will provide a detailed delineation of the boundary of the MRCCA, however, there are no additional shore impact zones or shoreland regulations identified or included in the city’s zoning ordinance or this plan. The only area of “shoreland” is along the Fort Snelling State Park/Gun Club Lake region located within the city, for which no development has or will take place. Nevertheless, recognizing a shore impact zone would highlight the importance of protecting the river shore from development and vegetative removal, maintaining a buffer area between the river banks and urban development. Adding ordinance requirements for the shore impact zone will be considered by the city when it updates its zoning ordinance. Mendota Heights 2040 Comprehensive Plan June 2019 Critical Area (MRCCA) 9-10 9.1.4 Work with the DNR on height standards to determine appropriateheight restrictions, particularly on redevelopment areas with existingsite constraints.PRIMARY CONSERVATION AREAS (PCA)General OverviewAs the DNR’s Statement of Needs and Reasonableness (SONAR)defines it, theterm “primary conservation areas” (PCAs) addresses the key natural and culturalresources and features managed by MRCCA rules. These features are givenpriority consideration for protection with regard to proposed land development,subdivision, and related activity. PCAs include Shore Impact Zones (SIZ),Bluff Impact Zones (BIZ), floodplains, wetlands, gorges, areas of confluence with tributaries, natural drainage routes, unstable soils and bedrock, native plant communities, cultural and historic properties, significant existing vegetative stands, tree canopies and “other resources” identified in local government MRCCA plans. Shore Impact Zone Shore Impact Zones (SIZs) apply to the Mississippi and all of its backwaters, as well as to its four key tributaries, including the Crow, Rum, Minnesota, and Vermillion rivers.

As Map 9-4. FEMA Floodplains portrays, there is floodway on both sides of the Mississippi River and Minnesota River, but within the cities of St. Paul, Lilydale, Mendota, and Eagan. The floodway basically follows the northwest boundary of the city. See Map 9-4. FEMA Floodplain Map and Map 9-5. MRCCA Wetlands & Floodplains. There are a number of known wetlands identified within the MRCCA boundary in Mendota Heights. These wetlands and water features have been identified and mapped, and are made part of the city’s Surface Water Management Plan, which is provided as Appendix I. Map 9-4.

They may be permanently or temporarily inundated. There are a few identified natural drainage routes that flow from some of the city’s own water features and eventually towards the Mississippi River. The city’s existing topography acts to provide a natural northward flow pattern for most of these waterways, and the proximity of Interstate 494 to the south acts as a significant barrier to natural drainage to the south or into adjacent communities. See Map 9-6. MRCCA – Major Natural Drainage Routes. Bluffs & Bluff Impact Zones According to Minnesota Rules 6106.0050, subp. 10, a “bluff” is defined as a natural topographic feature having either of the following characteristics: A.a slope that rises at least 25 feet above the ordinary high water level or toe of the slope to the top of the slope; and the grade of the slope from the ordinary high water level or toe of the slope to the top of the slope averages 18 percent or greater, measured over a horizontal distance of 25 feet; or B.a natural escarpment or cliff with a slope that rises at least 10 feet above the ordinary high water level or toe of the slope to the top of the slope with an average slope of 100% or greater. The development and land use standards are tied to the Bluff Impact Zone (BIZ). In the MRCCA, the rules in the BIZ are more restrictive than those for land within the shoreland area. They prohibit the placement of structures, land alteration, vegetation clearing, stormwater management facilities, and most construction activities in the BIZ. However, some limited exceptions to these restrictions, such as for public utilities and recreational access to the river, are allowed. This greater degree of protection is necessitated by development pressures on bluffs throughout the river corridor and the susceptibility of these features to erosion and slope failure. Mendota Heights has several areas or narrow strips of land identified as a BIZ within the MRCCA boundary. See Map 9-7. MRCCA – Bluff Impact Zones. 15 Chapter 9 - MRCCA City of Mendota Heights 2040 Comprehensive Plan Update Mendota Heights 2040 Comprehensive Plan June 2019 Critical Area (MRCCA) 9-14 Natural Drainage Ways Natural drainage ways are linear depressions that collect and drain surface water.They may be permanently or temporarily inundated.

MRCCA - Bluff Impact Zones Source: Metropolitan Council 17 Chapter 9 - MRCCA City of Mendota Heights 2040 Comprehensive Plan Update Native Plant Communities & Significant Existing Vegetative Stands Native plant communities are plant communities that have been identified as part of the Minnesota biological survey. They represent the highest quality native plant communities remaining in the MRCCA. Significant vegetative stands are plant communities identified by the National Park Service that are largely intact, connected and contain a sufficient representation of the original native plant community. Much of this vegetation contributes to the scenic value of the MRCCA. Mendota Heights has one large area of native plant communities within the city and its MRCCA boundaries, which primarily encompasses Fort Snelling Park/Gun Club Lake reserve. There are also a number of significant [existing] vegetative stands in the MRCCA. See Map 9-8. MRCCA – Native Plant Communities and Significant Existing Vegetative Stands. The Corridor generally exhibits a mostly wooded and natural vegetative character, with a variety of other vegetative environments like prairie, shrubs and wetlands. These wooded areas are mostly located within or near the Fort Snelling/Gun Club lake area, and in smaller developed and undeveloped area inside the MRCCA boundary. Tree species include oaks, maples, cottonwood, elms, and Linden (basswood) trees along with a wide variety of evergreen trees such as white pine, black hill spruce, blue spruce and others. Unfortunately, the Corridor is also impacted by some invasive species, such Siberian elms, black locusts, and buckthorn. Regardless of these desired and invasive plants, these wooded and vegetative areas naturally provide limited animal habitat areas, and offer natural erosion control measures, especially those located on slopes and bluffs. Previous and current efforts to prevent and control elm and oak tree diseases have been generally effective in preserving these forested resources. Throughout the course of the years, the city has carefully regulated all new development and redevelopment sites within the Mississippi River Corridor Critical Area, and the regulations have controlled the loss of woodland and other significant vegetation on bluff areas and slopes whenever land development was requested. 18 Chapter 9 - MRCCA City of Mendota Heights 2040 Comprehensive Plan Update Map 9-8. MRCCA - Native Plant Communities and Significant Existing Vegetative Stands Cultural & Historic Properties The City of Mendota Heights does not have a historic preservation ordinance, but supports preservation through state and national registers. As opportunities for preservation are discovered, the city will handle them on a case-by-case basis, drawing from resources such as the Minnesota Historical Society, Dakota County, and community/non-profit organizations. According to the Minnesota Historical Society, the following properties in the city are listed on the National Register of Historic Places, and are located in the MRCCA: Mendota Heights 2040 Comprehensive Plan June 2019 Critical Area (MRCCA) 9-18 FIGURE 9-9.

MRCCA Native Plant Communities & Vegetation Map Source: Metropolitan Council 19 Chapter 9 - MRCCA City of Mendota Heights 2040 Comprehensive Plan Update •Fort Snelling – Mendota Bridge – Is a steel-reinforced, continuous-arch concrete bridge located on Minnesota Highway 55 over the Minnesota River. It was built in 1925-26, according to the plans prepared by Walter Wheeler and C.A.P. Turner. The bridge was reconstructed between 1992 and 1994, reflecting the original design. •St. Peter’s Church – This church complex includes one of the oldest church buildings used by Minnesota’s early settlers of the Mendota area, and is still in use today. The church was constructed in 1840. Growth of the congregation has resulted in the addition of several other buildings on the site, although the historic building remains in use. Adjacent to the Mendota Bridge is Pilot Knob which warrants mention given its historic significance in the area. While not in the MRCCA, the landmark is adjacent and may be partially visible from MRCCA protected areas. •Pilot Knob – Currently restored and protected to its pre-development condition, the Pilot Knob area, just off of the east end of the Mendota Bridge, has special historical meaning through a wide spectrum of Minnesota history. The city and other public agencies have acquired much of the property and are adding interpretive facilities to the site as opportunity permits. Unstable Soils & Bedrock The city has not conducted or completed a comprehensive review or analysis of unstable soils or bedrock in the MRCCA. However, if and when development is proposed the city will require soil borings and geotechnical analysis to demonstrate stability of any proposed development area. Further development conditions may include protection of signficant trees, plans for revegetation, groundwater monitoring, etc. In addition to potential development area, the Gun Club Lake and Fort Snelling State Park area includes some bluff land which may be susceptible to erosion. This area is protected as permanent parkland and open space, and there are no development plans or vegetative alterations planned in this protected areas. St. Peter’s Church - 1840 20 Chapter 9 - MRCCA City of Mendota Heights 2040 Comprehensive Plan Update Public River Corridor Views Public river corridor views (PRCVs) are views toward the river from public parkland, historic properties, and public overlooks, as well as views toward bluffs from the ordinary high water level of the opposite shore, as seen during the summer months. PRCVs are deemed highly valued by the community and are worth protecting because of the aesthetic value they bring to the MRCCA. Views Toward the River from Public Places The existing tree coverage and topography in Mendota Heights limits some views toward the Mississippi River from public places and portions of the Corridor contain private properties within the MRCCA boundary. Map 9-9. Public River Corridor Views identifies views from Mendota Heights at the opposite shore, and views from other communities looking at the Mendota Heights shoreline. As demonstrated, there are several locations where views of the shore are important and valuable. Four locations are identified on Map 9-9. Public River Views including: 1) View from Big River Regional Trail is important because it includes both a view of the Mississippi River Corridor, Gun Club Lake preserve and part of the City of St. Paul skyline; 2a) View provides both easterly and north-south views of the river corridor, and bluffs are visible; 2b) View provides serene view of shoreline and bluffs; and 3) View from Lilydale Regional Park provides bluff and shoreline views towards Mendota Heights. These views may be negatively impacted if significant vegetative clearing were to occur, especially if such activities compromised the stability of the bluffs. As a result, vegetative management and preservation is a priority for the city as it prepares its zoning ordinance to support this Plan. 21 Chapter 9 - MRCCA City of Mendota Heights 2040 Comprehensive Plan UpdateMinnesota RiverMinnesota RiverMississippi RiverMississippi RiverMendota HeightsMendota HeightsSaint PaulSaint PaulMendotaMendotaFort Snelling (unorg.)Fort Snelling (unorg.)LilydaleLilydaleIntermittent River Views on Big River Intermittent River Views on Big River Regional Trail Corridor*Regional Trail Corridor**Significant portion of river frontage is not within Mendota Heights*Significant portion of river frontage is not within Mendota HeightsF00.51Miles2b.

Policies 1.Adopt a new MRCCA ordinance overlay district compliant with the goals and policies of the MRCCA plan, and with Minnesota Rules, part 6106.0070, Subp. 5 - Content of Ordinances; and work with the MnDNR on flexibility with the ordinance as noted in previous sections of this Plan. 2.Support mitigation of impacts to PCAs through: subdivisions/PUDs, variances, CUPs, and other permits. 3.Prioritize the restoration and protection of Native Plant Communities and natural vegetation in riparian areas a high priority during development. 4.Support alternative design standards that protect the Local Government Units (LGU’s) identified PCAs, such as conservation design, transfer of development density, or other zoning and site design techniques that achieve protection or restoration of primary conservation areas. 5.Protect and prioritize through permanent protection measures, such as public acquisition, conservation easement, deed restrictions, etc., which protect PCAs in the corridor. 6.Create and update ordinances that protect and minimize impacts to PCAs from public and private vegetation management activities. 7.Work with adjacent communities to determine appropriate protection of identified PCAs. 23 Chapter 9 - MRCCA City of Mendota Heights 2040 Comprehensive Plan Update Primary Conservation Areas - Implementation Actions •Ensure that information on the location of PCAs is readily available to property owners to understand how PCA-relevant ordinance requirements, such as vegetation management and land alteration permits, apply to their property for project planning and permitting. Establish procedures and criteria for processing applications with potential impacts to PCAs, including: -Identifying the information that must be submitted and how it will be evaluated, -Reviewing appropriate mitigation procedures/methods for variances and CUPs; and -Establishing evaluation criteria for protecting PCAs when a development site contains multiple types of PCAs and the total area of PCAs exceed the required set aside percentages. -Developing administrative procedures for integrating MnDNR and local permitting of riprap, retaining walls and other hard armoring. -Actively communicate with other communities to protect views that other communities have identified as valuable, as well as to protect views identified by the city through this process. 24 Chapter 9 - MRCCA City of Mendota Heights 2040 Comprehensive Plan Update PRIORITIES FOR RESTORATION General Overview Natural vegetation is critical to the health of the ecosystem along the Mississippi River corridor, providing important habitat for area wildlife and natural function of plant and waterway systems. The MnDNR has identified a number of high priority areas for restoration of natural vegetation, not only within the established Critical Corridor Area, but in other areas throughout the city, including lakes, streams, wetlands, and drainage ways. These areas were determined based on identifying existing significant stands of vegetation, areas of erosion, and areas of needed stabilization. MRCCA requires communities identify areas that are priorities for restoration due to poor quality natural vegetation or bank erosion issues. Much of the Critical Corridor Area is wooded and vegetated, with a large expanse of open space and park or vegetated residential land. If development or redevelopment occurs within MRCCA, protection of existing vegetation or restoration will be required in accordance with MRCCA ordinance requirements. Mapping for Mendota Heights was completed by MnDNR and Metropolitan Council and is identified on Map 9-9. Vegetation Restoration Priorities. The city has not identified any specific areas of concern for erosion prevention, bank and slope stabilization or other restoration activities. As noted, the city will incorporate standards into its ordinance to address future study and analysis as development or redevelopment occurs to ensure appropriate vegetation management and restoration activities are incorporated. 25 Chapter 9 - MRCCA City of Mendota Heights 2040 Comprehensive Plan Update Map 9-9.

MRCCA Vegetation Restoration Priorities Map Source: Metropolitan Council and MnDNR 26 Chapter 9 - MRCCA City of Mendota Heights 2040 Comprehensive Plan Update GOALS & POLICIES - Restoration Goal 3: Protect native and existing vegetation during the development process and require restoration if any is removed by development. Priorities for restoration shall include stabilization of erodible soils, riparian buffers and bluffs or steep slopes visible from the river. Policies 1.Seek opportunities to restore vegetation to protect and enhance PRCVs identified in this Plan. 2.Seek opportunities to restore vegetation in restoration priority areas identified in this Plan through the CUP, variance, vegetation permit and subdivision/ PUD processes. 3.Sustain and enhance ecological functions (habitat value) during vegetation restorations. 4.Evaluate proposed development sites for erosion prevention and bank and slope stabilization issues and require restoration as part of the development process. Restoration Implementation Actions •Ensure that information on the location of natural vegetation restoration priorities is readily available to property owners to understand how relevant ordinance requirements apply to their property for project planning and permitting. •Establish a vegetation permitting process that includes permit review procedures to ensure consideration of restoration priorities identified in this plan in permit issuance, as well as standard conditions requiring vegetation restoration for those priority areas. (Note: vegetation permitting process is a required element of MRCCA ordinance.) •Establish process for evaluating priorities for natural vegetation restoration, erosion prevention and bank and slope stabilization, or other restoration priorities identified 27 Chapter 9 - MRCCA City of Mendota Heights 2040 Comprehensive Plan Update in this plan in CUP, variances and subdivision/PUD processes. (Note: A process for evaluating priorities is a required element of MRCCA ordinance review and approval.) SURFACE WATER USES Mendota Heights has very little surface water use in the MRCCA other than recreational motorboats and small paddle crafts such as canoes and kayaks. There are no public boat launches or marinas in Mendota Heights; however there is a small private marina/boat dock associated with the Pool and Yacht Club in the City of Lilydale (located just east of the I-35E bridge crossing), and to which some residents of Mendota Heights belong. There is limited barge traffic that passes Mendota Heights, heading west on the Minnesota River to Ports Bunge and Cargill in Savage, and a loading facility in Burnsville just west of I-35W. No additional policies or implementations actions are applicable for surface water use for MRCCA in the City of Mendota Heights.

Most of the land adjacent to the river is primarily in the Gun Club Lake and Fort Snelling State Park preserve area on the far west edge of the community. There are no proposed new water-oriented uses for the city in the 2040 Planning Period. OPEN SPACE & RECREATIONAL FACILITIES General Overview Open space and recreational facilities, such as parks, trails, scenic overlooks, natural areas, and wildlife areas add to the quality of a community. One purpose of a MRCCA plan is to promote the protection, creation, and maintenance of these features and locations in each community along the metropolitan Mississippi River corridor. Fort Snelling State Park Fort Snelling State Park, with 849 of its 2,642 acres located in the city, is considered the largest in Mendota Heights. This park provides outdoor recreation opportunities and natural resource conservation for the public and is considered part of the regional recreational open space system. Fort Snelling State Park is a recreational state park offering swimming, large group and family picnic grounds, a boat launch, interpretive center and historical areas, trails, and scenic overlooks. A passive recreation area located within the boundaries of Mendota Heights, but situated across the Minnesota River is an area known as Picnic Island. This 75-acre tract of land appears to have been created or carved out by an “oxbow lake” feature in the Minnesota River corridor, and is located underneath the Highway 62/55 Bridge. The site is accessed from Hwy. 5 in St. Paul, off the Post Road/Snelling Lake Road exit ramp. Most of the park’s active facilities are located on the Bloomington side of the River, requiring most Mendota Heights residents to drive or bike across the I-494, I-35E and Mendota bridges. The Mendota Heights portion of the park is left primarily as a natural area as it contains extensive floodplain marsh habitat. Facilities located in Mendota Heights support less intensive uses, such as biking, hiking, cross country skiing, and fishing. The Sibley and Faribault historic sites in the City of Mendota Heights are also located on the Mendota Heights side of the River. 29 Chapter 9 - MRCCA City of Mendota Heights 2040 Comprehensive Plan Update Harriet Island-Lilydale Regional Park Located just north of Mendota Heights, this park is managed by the City of St. Paul. The lower portion of the park in the City of Lilydale is planned to remain passive open space. A beach and concessions area are planned, but eventual development is highly unlikely due to wetland issues. The area also has a ramp for boat access to the River. A trail through the park, separate from the roadway, is planned to link St. Paul to the Big Rivers Regional Trail. GOALS & POLICIES - Open Space & Recreational Facilities Goal 4: Protect and enhance the city’s open space and recreational facilities within the MRCCA through appropriate land use guiding and zoning implementation. Policies 1.Encourage creation, connection, and maintenance of open space and recreational facilities that provide access to the river. 2.Identify and encourage connections of CA-SR land to existing and planned parks and trails within the city. 3.Encourage land dedication requirements be incorporated into the city’s park dedication ordinance and park planning that provide public connections to the river, where possible. 4.Require new development to identify significant natural features such as steep slopes, bluffland, vegetation, etc., and protect such features into perpetuity through a conservation easement, or similar. Open Space & Recreational Facilities Implementation Actions •Continue to review, track, and monitor open space required as part of the subdivision review process and ensure land that meets the policies stated herein are considered for land dedication at time of plat approval. TRANSPORTATION & PUBLIC UTILITIES There are no existing or future planned public transportation facilities located within the MRCCA corridor in the City of Mendota Heights. Chapter 3. Transportation of this Plan provides detail regarding planned roadway and transit improvements in the city over this Planning Period. 30 Chapter 9 - MRCCA City of Mendota Heights 2040 Comprehensive Plan Update Electric Power Generating Facilities There are no existing or planned power generating facilities, such as solar farms or wind generation facilities located within the PCAs or within areas identified as public river corridor views (PRCVs). There are existing overhead electric lines within the corridor, which are generally shown on Map 9-10. Approximate Location of Overhead Power Lines. While these essential services are visible, they are an existing condition and there are no known plans for these utilities to buried, or enlarged, in the corridor. There are no other utility impacts planned or anticipated to occur over this Planning Period. The City does not permit community solar farm installations in any zoning district. Personal or residential solar panels are permitted, and the city will evaluate its standards regarding these standards as part of its ordinance update and implementation of this Plan. Map 9-10.

CITY OF MENDOTA HEIGHTS 2040 Comprehensive Plan Update Chapter 10: Water Supply & Sanitary System This page is intentionally blank. 1 Chapter 10 - Water Supply & Sanitary System City of Mendota Heights 2040 Comprehensive Plan Update 10 WATER SUPPLY & SANITARY SYSTEM The purpose of this chapter is to provide general information regarding the city’s existing and future water supply/service networks; surface water and stormwater management; and waste water management. Water Supply Systems In 2016, the city transferred the ownership of its municipal water supply system to the St. Paul Regional Water Services (SPRWS). SPRWS provides water to all of Mendota Heights’ properties, and owns the water tower and distribution system. SPRWS also maintains the water lines and hydrants and bills its customers directly. The two-million-gallon water tower, located on Lexington Avenue, next to the city’s Public Works Facility, also provides reserve water capacity. GOAL 1. The city will assist SPRWS in maintaining a safe, clean, resilient and cost-effective water supply system for the community. Policies 1.The city will encourage regular testing and independent analysis of water samples as needed. 2.The city will encourage and help conduct seasonal hydrant flushing of mains. 3.The city will encourage residents and local businesses to implement seasonal irrigation system/lawn sprinkling restrictions. 4.Complete capital improvement projects to maintain infrastructure. 5.The city will work with SPRWS to maintain an affordable water utility rate for the residents and businesses. 2 Chapter 10 - Water Supply & Sanitary System City of Mendota Heights 2040 Comprehensive Plan Update 6.The city will cooperate and work in conjunction with SPRWS to provide or offer extension of water supply utilities to surrounding communities to service future development, if needed, and only if the local system is capable and without compromising the ability to service Mendota Heights’ properties. Surface Water & Stormwater Management The city’s Public Works Department is responsible for handling stormwater runoff, both to reduce flooding and to protect water quality. This has been identified as an important issue for Mendota Heights. The city completed a Surface Water Management Plan (July 2018), which is made part of this Comprehensive Plan Update, detailing the programs and policies for surface water management in the city, and is included as Appendix I. GOAL 2: Provide effective stormwater management and protection for existing lands throughout the community, and ensure future development/redevelopment areas do not pose any threat or create any harmful impacts to surrounding areas and water features. Policies 1.Maintain and improve the following in the community and other affected jurisdictions: -Water quality and quantity; -Erosion and sediment control; -Public water bodies, including lakes, streams and wetlands; -Public participation, information, and education; -Maintenance and inspection; -Recreation, fish and wildlife; and -Analyze and consider appropriate measures to reduce salt use on local roadways. 3 Chapter 10 - Water Supply & Sanitary System City of Mendota Heights 2040 Comprehensive Plan Update GOAL 3. Implement the Surface Water Management Plan. Policies 1.Continue to educate and provide the city’s residents and developers of the policies and standards under the city’s SWMP, and ensure sites meet or exceed SWMP rules and standards. 2.Carefully review and approve on-site stormwater treatment systems on future development or redevelopment projects. 3.Carefully monitor, inspect and permit municipal separate storm sewer system (MS4) regulatory activities throughout the city, to ensure the reduction to the amount of sediment and other pollutants entering water bodies from city stormwater systems. 4.Cooperate with local watershed groups to ensure compliance with policies and standards in the SWMP, and provide for any changes or amendments as recommended or needed. 5.Continue to implement an effective city-wide street sweeping program. 6.Maintain best management practices (BMP’s) in the maintenance of areas in the respective watershed districts and development sites, which include the following: -Public education and outreach; -Public participation and involvement; -Illicit discharge detection and elimination; -Construction site stormwater runoff control; -Post-construction stormwater management; and -Pollution prevention. 4 Chapter 10 - Water Supply & Sanitary System City of Mendota Heights 2040 Comprehensive Plan Update Wastewater Management The city’s Public Works Department operates and maintains the city’s sanitary sewer system. The responsibilities of the sanitary sewer system include maintenance of the sanitary sewer lift stations, sanitary sewer main repair, and sanitary sewer hook-up inspections. The sanitary sewage system in Mendota Heights was developed based upon the Sanitary Sewer System Master Plan dated March 28, 1966. In 1972, the Plan was approved by the Metropolitan Council and Metropolitan Sewer Board. The city is a fully sewered community with the exception of the Somerset Rural Residential neighborhood and a limited number of scattered sites that still utilize private, on-site septic systems. The collection and treatment of sanitary wastewater is a primary function of the city and the Metropolitan Council Environmental Services (MCES). All properties served within Mendota Heights ultimately flow to MCES interceptor laterals. The vast majority of the city’s collection system flows via gravity toward a MCES interceptor comprised of a three barrel Mississippi River Crossing (Siphon) that flows from south to north at the north end of the city. Since the city is nearly fully developed, the vast majority of properties are connected to the public sanitary sewer collection network. It is expected that all properties within the city will eventually be served by the system. The city also operates five lift stations as part of its system. The following Goal and Policies will guide the city’s future wastewater system planning during this Planning Period. GOAL 4. Maintain and improve the wastewater system to serve existing and future development. Policies 1.Maintain and improve the following in the community and other affected jurisdictions: -Require properties to connect to the system when appropriate, as part of utility or road reconstruction projects, when feasible; -Continue to implement the annual sanitary sewer televising program and address any issues as part of street reconstruction projects; -Continue to implement the annual sanitary sewer lining program in areas suspected to have Inflow and infiltration (I/I) potential; 5 Chapter 10 - Water Supply & Sanitary System City of Mendota Heights 2040 Comprehensive Plan Update -Plan for localized improvements and expansions to accommodate foreseeable growth and redevelopment; and -Consider extension of wastewater utilities to surrounding communities to service future development, as long as the system is capable and without compromising the ability to service Mendota Heights’ properties. Metropolitan Sewer Service The city is served by the regional sewer interceptor line listed in the following table and one other metershed district. No new trunk systems are anticipated. Metershed M063AB serves nearly 97 percent of city. The remainder of the city is served by metershed M001 which flows directly into a St. Paul system at Chippewa Avenue and Annapolis Street. The total 2018 sewer flow for all properties was approximately 554,900,000 gallons. The table shows the forecast changes in demographics and sewage flow. The estimated total outflow when the city is fully developed (after year 2030) 557,000,000 gallons per year. Table 10-1.

With inflow, clear water enters the regional wastewater system through rain leaders, sump pumps, storm sewer cross connections, and foundation drains connected to sanitary sewer pipes. Inflow is greatest during major storm events and can more than triple wastewater volumes. Infiltration is a more gradual process, and occurs when water seeps into sanitary sewer pipes through cracks, leaky pipe joints and/or deteriorated manholes. Excessive I/I in sewer systems create multiple problems: •Expensive treatment of clear water •Reduced interceptor capacity •Water quality •Less recharge to aquifers The clearwater flow entering the sanitary sewer system was estimated using city-wide MCES meter data from 2015 to 2019. The average annual I/I rate and peak month I/I rate were calculated as the difference between the average flow and the base flow. The base flow was approximated as the lowest monthly flow within each year. The estimated clearwater flow is listed in Table 10-5. 10 Chapter 10 - Water Supply & Sanitary System City of Mendota Heights 2040 Comprehensive Plan Update Table 10-5. Estimated I/I Rate Year Average Flow (MGD)Average I/I Rate Peak Month Flow (MGD)Peak Month I/I Rate 2015 1.32 18%1.67 35% 2016 1.48 13%1.67 23% 2017 1.44 14%1.84 33% 2018 1.39 16%1.65 29% 2019 1.59 18%2.00 35% Average 1.44 16%1.77 31% Source: Mendota Heights, WSB I/I Potential Sources Inflow and Infiltration (I/I) can come from several sources contributing non-sanitary flow into the sanitary sewer system. Example sources include surface runoff from roofs and manholes drainage from draintile and sump pumps, aging housing stock (see Table 10-6. Age of Housing Stock) and leaks from failing sanitary infrastructure. As shown, approximately 43% of the city’s housing stock was constructed pre-1970 and approximately 50% of those properties have been evaluated for I/I susceptibility and repair. The Metropolitan Council establishes I/I goals in the 2040 Water Resources Policy Plan for all communities discharging wastewater to the Metropolitan Disposal System (MDS), which Mendota Heights addresses in subsequent sections of this chapter.

In 2016, a residential sump pump inspection program was completed. All houses were either compliant or altered their plumbing to eliminate connections to the sanitary sewer. Clearwater flow has not been measured or estimated beyond excessive flow monitoring performed by MCES and the high level estimate above. An analysis has not been completed to measure the amount of clear water flow generated from particular parts of the municipal public and private sewer systems. Schedules and funding have yet to be determined, but such an analysis would be completed in conjunction with I/I reduction efforts. Objectives for I/I Management Mendota Heights will continue its efforts to eliminate excess I/I with the following objectives for system management: •Replace sewer linings •Repair cracks and joints in public system •Monitor sump pump drainage •Educate property owners about reducing I/I The current I/I target for the City of Mendota Heights is an allowable peak hourly flow of 5.03 mgd. The Metropolitan Council’s metering program shows that the City of Mendota Heights’ 2020 Adjusted Average Daily Flow (AAF) was 1.437 mgd. Notwithstanding exceeding our I/I target, the City of Mendota Heights continues to seek opportunities to reduce clear water flow into the sanitary sewer system. Mendota Heights will also work cooperatively with other agencies and property owners to educate residents and businesses about the importance of reducing I/I and promote ongoing maintenance of infrastructure on private property. It is particularly important to inspect and repair damaged sewer service lines connected to the MDS, and replace older pipes that are beyond their useful life. 12 Chapter 10 - Water Supply & Sanitary System City of Mendota Heights 2040 Comprehensive Plan Update Implementation Plan The c ity has an annual sanitary sewer-televising program, and the entire system is televised and cleaned every six years. The c ity also undertakes an annual sewer-lining project in areas suspected to have I/I potential and annually lines approximately 10,000 feet of sanitary sewer through a public bidding process. The c ity continues to seek improvement in reducing potential I/I. An additional program under consideration is facilitating private sanitary sewer service inspections and repairs. This either could take the form of a new utility program or included as part of annual street reconstruction program activities. Additional emphasis will be placed on private connections when the public system relining process is nearing completion, which is 10+ years out. I/I Cost Estimates Schedules and funding remain to be determined, but it is expected that existing utility fees will be adequate as existing fund sources are reallocated to new improvement initiatives. Policies and Regulations Mendota Heights regulates against inflow and infiltration to the sanitary system from surface water sources in their city code. Section 10-3-10: Clear Water Discharge Prevention and Prohibition states that, “No clear water, as defined in section 10-1-1 of this title, shall be discharged, directly or indirectly, into the city’s sewer system;” and it further stipulates that, “No sump pump system shall discharge clear water into the city’s sanitary sewer system.” The City will continue to monitor compliance with this ordinance through its permitting processes. (See Appendix E for copy of applicable Code section). 13 Chapter 10 - Water Supply & Sanitary System City of Mendota Heights 2040 Comprehensive Plan Update Private Sewage Treatment Systems The city’s records indicate that approximately 42 properties are currently served by private sub-subsurface sewage treatment systems (SSTS). There are no other known public or privately-owned Community Wastewater Treatment Systems. The City Code contains regulations for private sewage treatment systems, which incorporates the provisions of Minnesota Administrative Rules Chapter 7080 (MPCA) and Dakota County Ordinance 113. The regulations include permissible system standards, prohibits installation of new private systems where public sewer is available, requires permitting for installation, alteration, repair, or extension, contractor licensing requirements, and penalties for non-compliance. Property owners are required to submit pumping reports for existing private systems to the C ity. Due to the low number of private systems in operation, the reporting and review process is sufficient to ensure property owners are performing the system maintenance.

These agreements outline methods of payment for sanitary sewer flow. In most cases, the Metropolitan Council Environmental Services (MCES) makes a flow correction to account for services outside of the city. The city of Mendota Heights bills the customer directly for services to these properties consistent with its ordinance. A description of the inter-community areas are generally identified below: A.Forty-four (44) single-family residential properties located along Delaware Avenue and north of Dodd Road (TH 149) are currently served by the City of West St. Paul. B.Approximately 125 single-family residential properties generally located in the northeastern section of the city are currently served by the City of St. Paul/MCES. Please note that the City does not have an agreement with the City of St. Paul, and therefore is not included. The properties served by St. Paul are billed and serviced by St. Paul, not the City of Mendota Heights. C.The adjacent community of Mendota currently serves St. Peter’s Church, located at 1405 Highway 13 under a separate agreement. D.The city provides wastewater service to five (5) single-family residential properties in the City of Sunfish Lake, located on the east side of Delaware Avenue Localized improvements may be needed to accommodate foreseeable growth and redevelopment. Otherwise, the current system is adequately-sized to serve the city’s current and forecast growth needs. Sanitary Sewer Line Extensions The city has identified the neighborhood bound by Marie Avenue to the south, Delaware Avenue to the east, Wentworth Avenue to the north and Dodd Road to the west as an area that will be served by an extended sewer system. This sewer extension will be tied to a reconstruction of Wentworth Avenue (County Road 8). This extension is not a trunk line, and the city has not identified a timeline for completion of this extension.

Discharge Requirements: 1. No "clear water", as defined in section 10-1-1 of this title, shall be discharged, directly or indirectly, into the city's sewer system. 2. All sump pump systems within the city shall meet the following requirements: a. No sump pump system shall discharge clear water into the city's sanitary sewer system; b. The sump pump system design shall provide year round discharge of clear water through a permanently installed discharge line from the interior of the structure to an appropriate drainage area on the outside of the structure, connection to the city storm sewer, or discharge through the curb and gutter to the street. In no event shall a drainage area include property owned by others or any public right of way unless said right of way is adjacent to a developed city street with an installed drainage system. Approval to discharge to storm sewer or streets must be obtained from the city; c. The sump pump system's permanent discharge line shall be made of solid, nonflexible material and shall not have any connection fittings as to permit alternative flow path subsequent to installation; and d. If the sump pump system discharge line is connected directly to the city's storm sewer system, then the discharge line shall have a check valve which shall be located within the property's boundaries and not within the public right of way. B. Inspections: 1. Inspections Required: Any property within the city that is connected to the city's sewer system shall be subject to one, no cost compliance inspection, and a subsequent follow up inspection, to determine whether the property's discharge of its clear water is in compliance with this section and is not discharged into the city's sanitary sewer system. a. Property owner or occupant shall permit the city's designated inspector on the property and within any structure thereon to complete the inspection. b. The compliance inspection shall occur within thirty (30) days of written notice from the city that a compliance inspection is required on the property. c. The compliance inspection shall occur at a time and in the manner as reasonably determined by the city's designated inspector. d. In lieu of a compliance inspection by the city inspector, property owner may have the property inspected, at the sole expense of the owner, by a private licensed plumber who shall inspect the property and file a certificate of compliance on a form provided by the city, within thirty (30) days of the city's notice of the required inspection. e. The private licensed plumber who conducts the compliance inspection shall certify on the certificate of compliance that the property's discharge of clear water is in compliance or noncompliance with the provisions of this section. f. In the event that the inspector cannot complete the compliance inspection because the property's sump pump and/or sewer "cleanout" is not readily accessible as required by the state building code, the property owner or occupant shall take all necessary steps to make the sewer cleanout readily accessible for the reinspection to be completed within thirty (30) days of the date the inspector was at the property to conduct the initial inspection. g. If the property owner or occupant fails to make the sewer line cleanout accessible for inspection, such failure shall constitute a failure to comply with inspection requirements and subject to the quarterly surcharge as defined in subsection 10-3-7C6 of this chapter. 2. Failure To Comply With Inspection Requirements: a. Property owners or occupants are required to permit authorized city employees and/or agents to enter upon properties and inside structures for purposes of inspection under section 10-3-9 of this chapter. b. If the property owner or occupant fails to permit or have completed a compliance inspection, the city may apply to the district court for an appropriate administrative search warrant authorizing the city to enter the property to conduct the inspection. 3. Reinspections: a. In the event that the discharge of clear water on the property is not in compliance with this section, a second compliance inspection shall be completed within sixty (60) days of the notice of noncompliance to determine if the necessary corrections have been made and compliance with this section has been met. b. The second compliance inspection shall be subject to the requirements set forth above. Thereafter, the property shall be subject to reinspections on an annual basis to confirm continued compliance. c. Properties that are in compliance shall also be subject to reinspections to confirm continued compliance. C. Corrections: 1. Upon notice that the discharge of clear water on the property is not in compliance with this section, the owner or occupant of the property shall immediately cease from discharging clear water in violation of this section and shall make the necessary repairs and corrections to discharge the clear water in accordance with this section. These repairs and corrections shall be completed within sixty (60) days of the date of notice of noncompliance. 2. If necessary repairs and corrections are not completed within the sixty (60) days, it shall constitute a failure to comply with the requirements of this section and the owner of the property shall be subject to the quarterly surcharge as defined in subsection 10-3-7D of this chapter. D. Inspections With Building Permits: If a city inspector is on a property for the purpose of a building permit inspection, the city inspector has the authority to inspect the property for compliance with this section without further notice to the property owner or occupant. E. Temporary Waiver: 1. The city may grant a temporary waiver from the provisions of this section where strict enforcement would cause a threat of damage or harm to other property, the environment, or public safety because of circumstances unique to the individual property or due to weather conditions. 2. A written request for a temporary waiver must be first submitted to the public works director specifying the reasons for the temporary waiver. a. If a temporary waiver is granted, the property owner shall pay an additional fee for sewerage service charges based on the number of gallons discharged into the city's (sanitary) sewer system as estimated by the public works director. b. The additional sewerage service charge fee shall be established in the city's fee schedule and shall consist of a minimum base charge plus a charge based on the number of estimated gallons of clear water discharge. 3. The public works director may set conditions to the temporary waiver. 4. The public works director may terminate the temporary waiver upon a failure to comply with any conditions imposed on the temporary waiver. 5. The public works director must give a five (5) day written notice of the termination to the property owner and occupant setting forth the reasons for the termination. 6. After expiration or termination of a temporary waiver, the property owner shall comply with the provisions of this section. (Ord. 496, 6-7-2016) APPENDIX F Land Use Changes from 2030 to 2040 Comprehensive Plan This page is intentionally blank. 1 Appendix F City of Mendota Heights 2040 Comprehensive Plan Update LAND USE CHANGES FROM 2030 TO 2040 COMPREHENSIVE PLANS The designated future land use for a number of properties in the city has changed between the 2030 Comprehensive Plan (in 2008) and this 2040 Comprehensive Plan (adopted in 2021). Below is a brief narrative and summary of these changes, illustrated in Map 2-3. Future Land Use Plan. •340 - D Street: This 0.86 acre parcel, referred locally as Jack’s Mfg. Co., was left blank on the 2030 Plan, and is now guided I-Industrial in the 2040 Plan to reflect its current use. There is also a small 0.27 acre triangular shaped parcel located behind this property, owned by the adjacent St. Peter’s Catholic Church. This parcel will be guided as P/S-Public/Semi-Public. •Pilot Knob Historical Site: This area consists of several parcels totaling over 32 acres in the westerly edge of the city, south of Highway 55 and either side of Pilot Knob Road and Highway 13. The westernmost parcel is owned by the Minnesota DNR; and all others by the city. In the 2030 Plan the DNR parcel was guided Right-of-Way and the city parcels were guided Parks & Nature Preserve. That land use category has been replaced with the designation Park/ Open Space, hence the change between the 2030 and 2040 Plans. The existing and intended use of all the parcels is consistent with the designation Parks/ Open Space. •Valencour Circle (2085 Valencour Cir. & 2095 Hwy 55): Two residential parcels on Valencour Circle, fronting Highway 55 north of Acacia Boulevard, were guided NP-Nature Preserve in the 2030 Plan, but being single-family residences they have been changed in the 2040 Plan to LR-Low Density Residential, reflecting their current use. •2160-2180 Highway 13 (between Acacia Drive & Victory Ave.): Up until 2017, these properties housed an old landscaping-nursery business and a motel, which were razed and redeveloped for a new apartment development. The 2030 Plan guided the properties as Business, but in 2017 the city approved the guiding of these sites to HR-High Density Residential, reflecting their future and intended use (refer to Res. No. 2017-43; adopted 06/06/17). 2 Appendix F City of Mendota Heights 2040 Comprehensive Plan Update •Augusta Shores / Lemay Shores Townhomes: The Augusta Shores and Lemay Shores residential developments were both guided Low Density Residential in the 2030 Plan, but as twin-homes, it is more appropriate as Medium Density Residential in the 2040 Plan, reflecting their actual use. There are also several parcels within each development owned in common by the homeowners association as permanent open space or conservation easement, so identifying these areas as Park/Open Space is appropriate. •Lexington Avenue and Centre Pointe Curve: The city owns a vacant 1.2- acre parcel in the southwest quadrant of Lexington Avenue and Centre Pointe Curve, backing up to Highway 62. It was guided Parks & Nature Preserve in the 2030 Plan, but as a city-owned parcel is guided Public/Semi-Public in the 2040 Plan. •Veronica Lane: There are two city-owned parcels at the end of Veronica Lane totaling 1.2 acres that were guided Low Density Residential in the 2030 Plan but are now guided Park/Open Space in the 2040 Plan, reflecting their actual use as permanent open space. •Lexington Avenue and Marie Avenue: The city owns two parcels in the southeast quadrant of Lexington Avenue and Marie Avenue that are permanent open space. They were guided Low Density Residential in the 2030 Plan but are now guided Park/Open Space in the 2040 Plan, reflecting their actual use. •Kingsley Estates: The Kingsley Estates townhomes on Lexington Avenue and Kingsley Circle occupy about 8.3 acres and were guided Low Density Residential in the 2030 Plan, but have been designated Medium Density Residential in the 2040 Plan, reflecting their actual use and density. •Caren Road: The city owns four parcels on Caren Road where it meets James Road and Lilac Lane, totaling about two acres. They were guided Low Density Residential in the 2030 Plan but are now guided Park/Open Space in the 2040 Plan, reflecting their actual use as permanent open space. •Victoria Highlands: The Victoria Highlands townhomes on the north side of Marie Avenue at Victoria Road occupy about 10 acres. They were guided Low Density Residential in the 2030 Plan but are now guided Medium Density Residential in the 2040 Plan, reflecting their actual use. 3 Appendix F City of Mendota Heights 2040 Comprehensive Plan Update • Eagle Ridge: The Eagle Ridge townhomes in the southeast quadrant of Marie Avenue and Victoria Road occupy about 22 acres. They were guided HR- High Density Residential in the 2030 Plan but are now guided MR-Medium Density Residential in the 2040 Plan, reflecting their actual use. • Valley View Heights Park: This small park at the corner of Cullen Avenue and Timmy Street was guided LR-Low Density Residential in the 2030 Plan but is now guided P-Park/Open Space in the 2040 Plan, reflecting its actual use as a city park. • Rogers Lake Park: This 2.3-acre parcel is part of Rogers Lake Park and had been guided Low Density Residential in the 2030 Plan but is now guided Park/Open Space in the 2040 Plan, reflecting its actual use as a city park. • Wagon Wheel Trail at Rogers Lake: The 3-acre city-owned parcel on the south side of Wagon Wheel Trail as it crosses Rogers Lake was guided Low Density Residential in the 2030 Plan, but is now guided Park/Open Space in the 2040 Plan, reflecting its actual use as permanent open space • Condon Court: Two parcels formerly addressed as 2511 and 2525 Condon Court were re-guided in 2015 from LB-PUD Limited Business-Planned Unit Development to MR-Medium Density Residential (refer to Res. No. 2015-02; adopted 01/06/15). The properties were later subdivided and rezoned R-2 Two Family Residential. These parcels will be guided in the 2040 Plan as Medium Density Residential, reflecting their current use. • 2357 Pagel Road: Two privately-owned parcels totaling 1.2 acres were shown in the 2030 Plan as Highway 149 right-of-way, but are actually privately owned parcels with 2357 Pagel Road. They are shown in the 2040 Plan as LR- Low Density Residential, reflecting their actual use. • Mendota Meadows (Monet Court): two parcels dedicated to the city for open-space/buffering and storm water pond. Re-guided from MR-PUD in the 2030 Plan to Park/Open-Space in the 2040 Plan. 4 Appendix F City of Mendota Heights 2040 Comprehensive Plan Update • Mendota Woods: The Mendota Woods single-family development on Arbor Court south of Mendota Heights Road was guided HR-PUD in the 2030 Plan, but is appropriately guided Low Density Residential in the 2040 Plan, reflecting the actual use. • Kensington PUD Townhomes: The Kensington PUD townhome development, south of Mendota Heights Road at Concord Way and Lockwood Drive, was guided HR-PUD in the 2030 Plan, but is now guided Medium Density Residential in the 2040 Plan, reflecting the actual use. • Kensington PUD Single-Family Homes: The Kensington PUD single- family development, in the southwest quadrant of Mendota Heights Road and Delaware Avenue, was guided MR-PUD in the 2030 Plan, but is appropriately guided Low Density Residential in the 2040 Plan, reflecting the actual use. • MnDOT Right-of-Way on Decorah Lane: A small triangular 0.76-acre parcel on MnDOT right-of-way fronting on Decorah Lane east of Dodd Road was guided Low Density Residential in the 2030 Plan, but is now guided Right-of- Way in the 2040 Plan, reflecting its actual ownership. • Friendly Marsh Park: A one-acre triangular parcel at the end of Apache Street is part of Friendly Marsh Park, but was guided Low Density Residential in the 2030 Plan. It is now guided Park/Open Space in the 2040 Plan, reflecting its actual use. • The Village (Dodd Road/Hwy 62/Market Street): A combination of city- owned outlots (total of 4.08 acres) located in The Village of Mendota Heights, was guided Mixed-Use PUD in the 2030 Plan, but are all guided Park/Open Space in the 2040 Plan, reflecting their actual use as permanent open space. • Somerset Area (Southwest Part): A large area in the southwest part of what was designated the Somerset Area Focus Area in the 2030 Plan was guided Rural Residential. It is actually developed as single-family residential on sewered lots and is guided Low Density Residential in the 2040 Plan. 5 Appendix F City of Mendota Heights 2040 Comprehensive Plan Update •Somerset 19 Condominiums: The two-building condo project at Dodd Road and Wentworth Avenue on 8.1 acres was guided Low Density Residential in the 2030 Plan, but is now guided Medium Density Residential in the 2040 Plan, reflecting its actual density and use. •723 - 3rd Avenue: The 3-acre privately-owned single-family parcel was guided Parks in the 2030 Plan, but is now guided Low Density Residential in the 2040 Plan, reflecting its actual single-family residential ownership use. •City Parcel, Highway 13 at Ivy Falls: A narrow 2.6-acre parcel of city-owned land fronting Highway 13 on the bluff where Ivy Falls drains toward the river between Wachtler Avenue and Sylvandale Road was guided Low Density Residential in the 2030 Plan. It is now guided Park/Open Space in the 2040 Plan, reflecting its actual use as permanent open space. •Ivy Hill - Ivy Keep Townhomes: The Ivy Hill –Ivy Keep community is comprised of approximately 19 acres near Dodd Road, Ivy Hill Drive and Maple Park Drive, and was originally guided Low Density Residential in the 2030 Plan, but is now guided Medium Density Residential in the 2040 Plan, reflecting its actual density and use. The exception is the Ivy Keep Association’s 2.67-acre vacant tract known as Outlot F, which has been requested to be re-guided to Park/Open Space, reflecting its actual use as permanent open space. •Lilydale Regional Park, St. Paul Parcel: A 0.7-acre parcel at the far northern edge of the city on the west side of Highway 13 is owned by the City of St. Paul and is within the Lilydale Regional Park.

This report is based on several types of information: market research, a review of existing reports, interviews with local developers and real estate professionals, and direct observation. Mendota Heights is a fully developed suburb. While that status limits opportunities for new development, there is a need to stay viable and attractive as the demographics of the Minneapolis-St. Paul metropolitan area shift. The population is growing, it is aging, and more households will be renters. Choices about purchasing and employment will also evolve. Decisions about housing redevelopment, retail support and location, and office and employment opportunities will influence Mendota Heights’ character as a desirable place to live. This report considers the housing, retail, industrial and office development sectors. It looks at regional trends, as well as conditions in Mendota Heights. It evaluates strengths and weaknesses of Mendota Heights locations with respect to these development sectors, and evaluates opportunities for additional growth and development. As the Mendota Heights comprehensive planning process progresses, the analysis and findings in this report will serve to inform decision-making. They will be further modified and augmented through the process of developing the comprehensive plan, based on discussion with policymakers, stakeholders, and others. Mendota Heights 2040 Comprehensive Plan Background Report – Market and Development Context 4 Tangible Consulting Services, December 2016 Residential Market Context Existing Conditions Mendota Heights is a fully developed first-ring suburb. Its abundance of open space, lakes and wooded areas give it a distinctly suburban and in some areas rural feel. Yet its central location gives it excellent access to downtown St. Paul and the greater metropolitan area. Housing in Mendota Heights is predominantly single family. Eighty percent of residential land is guided for low density housing, with an allowed 2.9 housing units/acre. (Source: 2030 Comprehensive Plan) Nine percent is guided rural residential which allows 1.1 units/acre. The remaining 11% of residential land is guided for medium to high density housing. Around 70% of existing housing units are single family homes. Roughly 15% are townhomes, and 15% are in apartment buildings. Owner occupied housing predominates. Less than 15% of housing units are renter occupied. Single family housing. Residential neighborhoods throughout the City are strong. Homes are generally well maintained. The great majority were built in the last 50 years, as illustrated in the map below. A smaller number of homes are older than that, and go back to the late 1800s and early 1900s. They are scattered throughout the community, but most are in the northeast area. Housing Development by Decade: Single Family Homes and Townhomes Source: Mendota Heights Assessor Data Homes in Mendota Heights are valued markedly higher than that of homes in neighboring communities, or homes in the Metropolitan Area as a whole. The median value of a single family home in Mendota Heights in 2015 was approximately $360,000. High home values are correlated with the higher household incomes that are typical in Mendota Heights. 0 1000 2000 3000 4000 5000 Census 1990 Census 2000 Estimates 2010 Estimates 2015 Mendota Heights Housing Types Single Family Homes Townhomes Duplex, Triplex, Fourplex Multifamily (5 units or more) 0 1000 2000 3000 4000 5000 1990 2000 2010 ACS 2011-2015 Mendota Heights Housing Tenure Owner occupied Renter occupied Vacant Mendota Heights 2040 Comprehensive Plan Background Report – Market and Development Context 5 Tangible Consulting Services, December 2016 Source: American Community Survey, 2011-2015 Market Value: Single Family Homes and Townhomes Source: Mendota Heights Assessor Data The map of homes by value shows a similar pattern to the map of homes by age. Higher value homes tend to be in the neighborhoods that were developed most recently. Multifamily housing. Although single family housing predominates in Mendota Heights, the city offers some townhome communities, as well as a few apartment and condominium buildings. There are four existing apartment developments in Mendota Heights. Three are for seniors. One is for general occupancy. An additional four-story apartment building with 139 units is being developed in the Hwy 110/Dodd Road area.

It offers more limited options, however, for a range of other household types. With a metropolitan household that is aging and diversifying, the interest in a broader set of housing choices will increase. Broadening the housing types available in Mendota Heights may be beneficial for attracting younger couples and families, and providing opportunities for older residents who are transitioning from large single family homes. Few opportunities are similarly available for the moderate to average income households that may serve as teachers in the City’s schools, or be employed in some of the City’s industrial businesses. The following two chart show the affordability of the City’s existing housing, and the number of housing units that are publicly subsidized.

This is partly due to the reduced ability of some households to meet the financial requirements of purchasing a home, and more stringent mortgage qualification requirements. But it also reflects changes in preferences—that is, an increased preference for renting versus owning one’s home. Aging population, the lifestyle choices of many millennials, and economic factors have made rental housing an increasingly popular choice. Twin Cities Apartments: Under Construction and Completed In the Twin Cities, developers have responded to the surge in demand for rental housing by developing more rental housing—most commonly high-amenity, market rate apartments. Condominium development has lagged—partly because of reduced demand, but also because production has been constrained by state statutes that govern developer liability. If liability statutes are loosened, that would open the door to increased condominium production. Apartment development has been largely focused in the strongest urban locations in the Metro—most notably downtown Minneapolis and St Paul, and strong urban transit and commercial nodes. There has been some suburban apartment development as well, and suburban development is increasing. Twin Cities Apartments: Eastern Metro Construction Activity, 2016 Source: Colliers International The surge in apartment supply has not yet quenched the demand. From the 12 months from Fall, 2015 through Summer, 2016, over 5,000 new units were constructed in the Twin Cities metro, and close to 4,000 units were already scheduled to be delivered in the 12 months through Summer, 2017. Twin Cities Apartments: Average Rent and Vacancy Apartment rents have continued to rise. Vacancy rates continue to be low overall, but a bifurcation has emerged between Class A and Class C buildings. Perhaps because there has been little construction of non-luxury apartments, there is a particularly low Mendota Heights 2040 Comprehensive Plan Background Report – Market and Development Context 8 Tangible Consulting Services, December 2016 vacancy rate in pre-1970s apartment buildings (98.7%), which are predominantly Class C buildings. The average vacancy rate in apartment buildings built after 2000 (mostly Class A buildings) is now over 5%. Market Dynamics – Mendota Heights As indicated in the following chart and map, the suburban communities around Mendota Heights are experiencing some apartment development in recent years. (Mendota Heights is in the S. St. Paul/Eagan Submarket in the following chart.) Apartment Unit Completions by Year Source: Colliers International Multifamily (MF) Apartment Construction around Mendota Heights Since 2010 Source: CoStar Market indicators. Demand for existing multifamily development seems strong. Although Costar only tracks two of the four existing apartment buildings in Mendota Heights, those buildings experience very low vacancy. The housing that was built at The Village at Mendota Heights was sold and occupied, even though some of it came online just before the start of the recession. Mendota Heights Apartment Vacancy Source: Costar Rents for multifamily units have been increasing steadily and in 2016 are at $1.10 per square foot. Mendota Heights Apartment Asking Rents (per Square Foot) Source: CoStar The market is strong enough to have attracted new market rate multifamily housing. A four story apartment building with 139 units is under construction near Hwy 110 and Dodd. It overlooks Dodge Nature Center and will be connected via pedestrian bridge to Mendota Plaza. Additional apartment and condo development seems likely to be supported by the market in certain locations in the community. But development opportunity sites in Mendota Heights are hard to find. Mendota Heights 2040 Comprehensive Plan Background Report – Market and Development Context 9 Tangible Consulting Services, December 2016 Development Considerations Strengths and weaknesses. Mendota Heights has important locational strengths and weaknesses for attracting housing development, and residential population. Strengths include: Its stable single family neighborhoods Its central location in the metropolitan area, with excellent transportation connections in all directions. Proximity to both downtown St. Paul and downtown Minneapolis. High quality schools, including three high schools—Henry Sibley, and St. Thomas Academy, and Visitation—which have regional reputations. Good quality neighborhood retail at Highway 100 and Dodd, including the unique retail environment offered by The Village, a mixed- use shopping area north of Hwy 110 and Dodd. High quality natural amenities including Dodge Nature Center, two golf courses, lakes and other natural areas, and proximity to the Mississippi River and trails. Challenges include: Limited options for transit service are available. Lack of retail goods and services, restaurants and entertainment, beyond those that are available at Highway 110 and Dodd Road. Development opportunities. Because Mendota Heights is fully developed, there is little opportunity for additional development of single family homes. Because there are few new home opportunities this close to the center of the metro, homes that are developed would likely be quite marketable. The proposed At Home Apartments development at Highway 110 and Dodd Road shows that Mendota Heights can attract the type of high amenity apartment construction that is being built in other parts of the region. It will build on the success of the housing that was built at The Village in Mendota Heights. It’s notable that new housing is being concentrated at the location in Mendota Heights where there are the strongest retail amenities and dining opportunities. Additional apartment development at this commercial node would likely be attractive and marketable, if suitable sites can be identified or assembled. Other locations where housing development may be viable in the coming decades include the following. Underdeveloped locations near Augusta or Lemay Lake. Existing golf course land, if its financial viability declines in the future. The attractiveness of existing housing in Mendota Heights, and the ability to attract new housing, would benefit from steps taken to strengthen the amenity base—particularly with respect to transit availability, and retail, dining and entertainment options. Strengthening these amenities may be important to maintaining Mendota Heights desirability and attractiveness as the tastes and demographic character of the Twin Cities evolves over the coming decades. Mendota Heights 2040 Comprehensive Plan Background Report – Market and Development Context 10 Tangible Consulting Services, December 2016 Retail Market Context Existing Conditions A city’s retail areas play an important role in its identity and attractiveness. Retail development in Mendota Heights is almost entirely focused at the crossroads of Highway 110 and Dodd Road. Two retail areas are present at this intersection – The Village at Mendota Heights, north of Hwy 110 at Dodd, and Mendota Plaza, across Hwy 110 to the south. These developments have distinctly different characters. The Village at Mendota Heights. The Village at Mendota Heights was developed over the period of 2001 to 2007. It is a neighborhood center in its scale of development, and the type of stores that anchor the development. But it has a destination market draw. Many of its customers come from Eagan, or from east and west of Mendota Heights, arriving via Highway 110. The Village at Mendota Heights The Village is a mixed-use area of retail and office, townhomes and condominiums, senior apartments, and a park. A unique, “new urbanist” style of development, it is a high density, walkable area that provides the opportunity to live close to shopping and offices, or park in the one of the parking lots and stroll along storefront-style stores, offices and restaurants. This “experience retail” can retain its attractiveness through shifts in the retail landscape, because it has a character that cannot be replicated through online purchasing. Mendota Plaza. Mendota Plaza is a more traditional neighborhood center. It is a strip center anchored by a Walgreens, a natural food store, a fitness facility and a restaurant. It has 60,000 square feet of retail floor area with surface parking in front of the stores. It was renovated within the past ten years, and is currently undergoing an 11,000-square foot expansion in conjunction with the development of a four story, 139- unit apartment building just to the east of the existing development along Highway 110. A pedestrian bridge will connect the apartments across a wetland area to Mendota Plaza. Another key factor in the expansion is the addition of driveway access into Mendota Plaza from Hwy 110. Mendota Plaza A regional trail is being developed that will cross Highway 110 at this location via a tunnel under Highway 110. Connecting to the Mississippi River in one direction, and the City of Eagan in another, the trail will effectively connect the two retail areas for bicyclists and pedestrians. Mendota Heights 2040 Comprehensive Plan Background Report – Market and Development Context 11 Tangible Consulting Services, December 2016 Market Dynamics – Regional Competitive Retail Context. The location of Mendota Plaza and The Village at Mendota Heights, relative to other retail areas in the area, has an important impact on the opportunity for additional retail development in Mendota Heights. The Retail Context Map illustrates the shopping centers in and around Mendota Heights, which are tracked by Costar according to type of center. Centers are given circular symbols that are illustrative of the size of the center. Large circles indicate regional centers. Small circles illustrate neighborhood- oriented retail centers. The City of Eagan, south of Mendota Heights is becoming a destination retail powerhouse on the scale of Woodbury. It added a new major retail development, Central Park Commons, on the former Lockheed Martin site at Pilot Knob Road and Yankee Doodle Road, west of Interstate 35E. That development includes a Hy-Vee grocery store, Marshalls, and other destination retailers. Twin Cities Premium Outlets is located a little further south at the intersection of Highways 13 and 77.The new Vikings headquarters and training facility, to be located near Interstate 494 at the intersection of Dodd Road and Lone Oak Parkway, will include office, retail, residential, hospitality and a conference center, and will become a destination in the region. The Eagan Promenade offers another cluster of destination retailers and restaurants at Yankee Doodle Road, east of I-35E. The retail offerings at these centers draw shoppers from Mendota Heights. New retail development tends to build on existing retail strength. So the retail primacy of Eagan dampens the attractiveness of Mendota Heights for destination oriented retailers. To the east, along Robert Street in West St Paul, there is a less upscale set of destination retail areas. The section of Robert Street between Wentworth and Marie Avenues hosts a Walmart, Target, and Lowe’s. The Signal Hills Shopping Center is at South Robert Street and Butler Avenue. The competing destination retail areas in Eagan and West St Paul, along with a scarcity of suitable retail locations in Mendota Heights, make it difficult to expand the retail footprint in Mendota Heights. On the other hand, the distance from Mendota Heights retail areas to competing retail areas in Eagan and West St Paul buffer the Mendota Heights retail areas from competition, and protect their long-term viability— since neighborhood centers offer goods and services that people don’t generally drive great distances for. Retail Context Map Mendota Heights 2040 Comprehensive Plan Background Report – Market and Development Context 12 Tangible Consulting Services, December 2016 Regional market indicators. The Twin Cities retail market has been reaping the benefits of the economic recovery. Absorption of retail space has been strong over the past five years, to the point that average retail vacancy metro-wide is at a very low 3.6%. And retail development has followed, reaching a post-recession high in 2016. Retail Vacancy, Absorption and Deliveries Twin Cities Metro Source: Costar Average asking rents per square foot have remained pretty steady over the same period at around $13.50 per square foot. Retail Asking Rents Per Square Foot Twin Cities Metro Source: CoStar Market Dynamics – Mendota Heights Market indicators. Though limited in scale, the retail areas in Mendota Heights are outperforming the metropolitan area as a whole. Costar data shows that the retail areas at Highway 110 and Dodd Road have continued to attract retail shops and services to the point where there is no vacancy in the two retail centers. No new retail has been constructed over the past five years, but that will change with the addition to Mendota Plaza. Retail Vacancy, Absorption and Deliveries Mendota Heights Source: CoStar Asking rents at these centers, at around $15 per square foot, are higher than the metro average of $13.50 per square foot. Retail Asking Rents Per Square Foot Mendota Heights Source: CoStar Mendota Heights 2040 Comprehensive Plan Background Report – Market and Development Context 13 Tangible Consulting Services, December 2016 Development Considerations Strengths and weaknesses. The retail areas in Mendota Heights benefit from their visibility from the heavily traveled Highway 110 corridor. Highway 110 carries a daily traffic volume of 20,000 to 30,000 ADT (average daily trips). They are the first retail center of any size on Highway 110 after crossing the Mendota Bridge from Minneapolis or Richfield. They also benefit from their distance from competing retail areas. In a sense, their distance from the centers in Eagan and West St Paul gives them a monopoly on neighborhood goods and services for residents in the surrounding neighborhoods. These locational characteristics are likely to keep the areas strong into the future. Another foundational strength of Mendota Heights retail is the relatively high income of its residents, relative to the metro area. Residents have the purchasing power to support neighborhood retail goods and services, as well as some distinctive restaurants and night spots. Mendota Heights is more limited in its prospects for destination retail. It is not likely to be able to develop a strong destination retail area, given the strength of destination retail areas in the surrounding communities. Development opportunities. There are limited opportunities for additional retail in Mendota Heights, and these include: At Mendota Plaza and The Village at Mendota Heights, limited opportunity may emerge for additional retail expansion, beyond what is already planned. There is a daytime population at Mendota Heights Industrial District which is underserved by restaurants and retail amenities. Although land is not available that would support the development of a large- scale retail center, there are several locations where a small footprint of retail could be developed to serve the district. Prospects for retail growth would be strengthened by increased housing, particularly that which is in close proximity to the retail expansion area. Retail areas can also be strengthened by building additional connections to them. Increasing bike and pedestrian connections from neighborhoods to existing retail may bring a different type of customer traffic, and strengthen the appeal of Mendota Heights to families. 14 Industrial and Office Market Context Employment in Mendota Heights The Minneapolis–St. Paul economy continues to boast one of the lowest unemployment rates in the country, currently hovering around 3.4 percent. Over 28,000 jobs were added in the last 12 months, and the metropolitan area benefits from the headquarters of 16 Fortune 500 companies as well as large local employers like the University of Minnesota. The local workforce ranks 11th in the country in terms of education, with 41 percent achieving a bachelor’s degree or higher. The average annual household income is $69,000, topping the national average by 29 percent. Mendota Heights has a unique employment profile for a Twin Cities suburb. Businesses in Mendota Heights offer a high number of good-paying jobs. And there are almost two jobs in Mendota Heights for every employed person who lives in Mendota Heights. While some jobs are in neighborhood serving retail businesses, and in its educational institutions, the great majority of jobs in Mendota Heights are in the industrial facilities and offices in the City’s industrial and office areas. Industry mix. Mendota Heights has a quite different business profile than the metropolitan area as a whole. It has a relatively small footprint in sectors that are commonly strong, such as health care, educational services, and retail. It has an unusual concentration of businesses and employment in the following industrial sectors:  Transportation and Warehousing  Administration and Support  Professional, Scientific, and Technical Services  Finance and Insurance Source: OnTheMap, US Census Bureau 0.0%5.0%10.0%15.0% Transportation and Warehousing Construction Administration & Support Management of Companies Wholesale Trade Finance and Insurance Professional, Scientific, Technical Services Accommodation and Food Services Retail Trade Educational Services Manufacturing Other Sectors Health Care and Social Assistance Industry Sectors, Mendota Heights & Metro Area MSP MSA Mendota Heights Mendota Heights 2040 Comprehensive Plan Background Report – Market and Development Context Tangible Consulting Services, December 2016 15 Inflow/Outflow. Most Mendota Heights workers commute to jobs outside of Mendota Heights. Of the roughly 5,500 workers who live in Mendota Heights, almost 95% go to work at a location outside the City. Around 300 Mendota Heights residents work at a business in Mendota Heights. Mendota Heights Job Inflow/Outflow Source: OnTheMap, US Census Bureau Location of industrial and office development. The majority of employment in Mendota Heights is focused in two distinct areas—the Mendota Heights Industrial District, and the Centre Pointe Business Park. Businesses in the Mendota Heights Industrial District (MHID) offer over 7,000 principal jobs. The MHID is home to a mix of industrial and office developments. Industrial development (that is, a facility that includes a warehouse or production component in addition to any finished office space) is most common. But there are also a number of buildings that are strictly office buildings, without a warehouse component. Industrial and Office Context Map Source: Mendota Heights Assessor Data The Centre Pointe Business Park offers around 800 jobs. The business park was developed in the 1990s and 2000s, and is comprised entirely of office buildings. Public benefits of employment areas. The Mendota Heights Industrial District offers a greater job density than many comparable industrial areas. This is partly due to the prevalence of office buildings in the District. Industrial and office jobs tend to pay a living wage which are higher on the average than jobs in some other sectors such as retail stores and services.

Industrial Market – Regional Metropolitan Area. The Twin Cities is a growing region with a vibrant and diversified economy—factors which support a positive long-term outlook for industrial development in the region. Industrial Absorption & Deliveries: Twin Cities Source: Costar Market conditions have strengthened in the industrial market. Metro-wide, there has been positive and strengthening absorption of industrial space over the past five years. New development of industrial space region-wide is at around 3 million square feet per year over the last four years. That’s up from around 0.5 million square feet per year in the preceding three years. But there’s still room to grow, since the historic average is around 5 million square feet of new industrial space per year. The ongoing absorption of industrial space over the last few years demonstrates a growing demand for the space, which manifests itself in two ways. First, the vacancy rate for industrial property has dropped over the past few years to under 5%. Industrial Vacancy: Twin Cities Source: Costar And second, average rents have been gradually rising, to a current blended rent rate of $6.50 per square foot. Industrial Asking Rents: Twin Cities Source: Costar Increasing rents lead to the development of new space, since stronger rents support a financial return for new development. South Central Submarket. Mendota Heights is in the South Central industrial submarket of the Twin Cities, as defined by Costar. The South Central Submarket encompasses cities such as West St Paul, South St Paul, Inver Grove Heights, Eagan, Apple Valley and 0.0 0.2 0.4 0.6 0.8 1.0 1.2 Land Value per acre Taxes per acreValue Compared to Mendota HeightsIndustrial Comparison Areas Mendota Heights Industrial District Burnsville Cliff Road Eagan Dodd Road Cottage Grove Business Park Mendota Heights 2040 Comprehensive Plan Background Report – Market and Development Context Tangible Consulting Services, December 2016 17 Burnsville, which are situated south of the Minnesota River and west of the Mississippi. The South Central Submarket is performing very similarly to the Twin Cities market as a whole, with an overall vacancy rate that has dipped to around 4%. Average asking rents are around $6.30, which is a little lower than the Twin Cities average rent. New industrial development in the South Central Submarket is coming online more slowly than in the metro area overall. Only three quarters of the last 12 have seen 100,000 or more square feet of new industrial product. Industrial Market – Mendota heights Strengths and weaknesses. Industrial development in Mendota Heights is located almost entirely in the 425- acre Mendota Heights Industrial District. Strengths and weaknesses of the area were assessed by a recent survey of stakeholders as part of the creation of the Mendota Heights Industrial District Redevelopment Plan. Strengths included:  Centrality of the location in the region  Airport proximity and access  Connection to regional transportation network  Flat topography  Well buffered from residential areas  Utility availability  Reasonable tax rate  Diversity of tenants in the district This impressive set of positive attributes makes the area highly attractive for industrial businesses. The district also has some weaknesses.  Limited opportunity for on-site facility expansion  Lack of retail or dining amenities  Absence of sidewalks  Airport noise  Limited transit access for workers Market indicators. Overall, these attributes result in strong utilization of the industrial space in the District, which has seen positive absorption over the last three years. The vacancy rate has correspondingly declined to around 3%, which is lower than that of the metropolitan area as a whole. Industrial Vacancy Mendota Heights Industrial District Source: Costar Area demand has also resulted in an increase in average asking rents in recent years to over $10 per square foot. Industrial Asking Rents Mendota Heights Industrial District Source: Costar Development considerations. The Mendota Heights Industrial District is attractively positioned for continued business occupancy, but there is not a lot of opportunity for new industrial development. Some properties can accommodate facility expansion, and that may well be pursued by the property owner or business tenant. The Mendota Heights Industrial District Redevelopment Plan makes several recommendations for actions to strengthen the area’s attractiveness to industrial users, and invite building renovation and improvement. These include:  Explore ways to communicate, brand, and promote the Industrial District  Consider city policies toward redevelopment incentives to potentially implement on future projects Mendota Heights 2040 Comprehensive Plan Background Report – Market and Development Context Tangible Consulting Services, December 2016 18  Consider investments in broadband and other technology infrastructure as necessary to ensure the area is competitive and serves the business needs Office Market – Regional The office buildings in the Mendota Heights Industrial District, and the Centre Pointe Business Park operate in a different competitive environment than the industrial facilities. Vacancy rates tend to be higher in office properties. There is a cachet effect that groups office development into clusters or districts within the metropolitan area. Transit availability, and proximity to amenities, are more important for attracting office tenants than they are for attracting industrial businesses. The following chart shows Twin Cities office space absorption over the past 9 quarters. There is a clear pattern of positive absorption of space, aside from the most recent quarter. This has brought the overall Twin Cities office vacancy rate down to around 7.5%. Metropolitan area rents vary by building class. They currently average around $25 per square foot for Class A office space, around $17.50 for Class B space, and around $15 for Class C space. Office Market – Mendota heights The office buildings in the Mendota Heights Industrial District and Centre Pointe Business Park are 20 years old on average. Together they offer around 1.4 million square feet of floor area. Buildings range in size from 6,000 square feet to 130,000 square feet. Many buildings are occupied by a single tenant, and many others have multiple tenants. Market indicators are mixed for the office buildings in Mendota Heights. The vacancy rate in 2016 is lower than the metropolitan area as a whole. But rents are also lower than the metropolitan average. Office Absorption, Deliveries and Vacancy Mendota Heights Source: Costar Office Average Asking Rent Mendota Heights Source: Costar Development considerations. The office districts in Mendota Heights have some strengths and face some challenges. As is true for industrial businesses, centrality in the region, and access to the freeway transportation network are significant strengths. However, the weaknesses of the area are more detrimental to the viability and attractiveness of the area to office tenants than they are for industrial Mendota Heights 2040 Comprehensive Plan Background Report – Market and Development Context Tangible Consulting Services, December 2016 19 businesses. The relative lack of amenities in or near the Mendota Heights Industrial District was cited as a particular concern by real estate professionals that were interviewed for this report. Offices at the Centre Pointe Business Park are better situated in this respect than those in the Mendota Heights Industrial District. Other liabilities, such as airport noise, and the limited nature of transit service, have a dampening impact on the Mendota Heights office market. The Mendota Heights Industrial District Redevelopment Plan suggested consideration of guiding land along Interstate 494 for office development over the long term, as opposed to a mix of office and industrial. This may strengthen the attractiveness of the area to office users, and clarify an office-oriented brand for the southern part of the industrial district. On the other hand, the market support for additional office development in the area is not assured. To support continued viability of the office areas in Mendota Heights, consideration could be given to actions such as:  Strengthen the office identity and branding of the southern part of the Mendota Heights Industrial district. Let the district be part of a broader Eagan/Mendota Heights office district  Build the amenity base of the area with the addition of some retail and restaurants, even if the opportunities for doing this are limited Mendota Heights 2040 Comprehensive Plan Background Report – Market and Development Context Tangible Consulting Services, December 2016 APPENDIX H Mendota Heights Capital Improvement Plan 2019-2023 This page is intentionally blank. City of Mendota Heights 2019 – 2023 Capital Improvement Plan July 13, 2018 To the Honorable Mayor and City Council Members: The purpose of the Capital Improvement Plan (CIP) is to provide a long range improvement plan to meet the needs of our community. The CIP provides policy makers and the community with a strategic approach to the implementation and administration of improvement projects. Decisions about improving the city’s infrastructure must be made not only on the basis of need, but also on the basis of availability of resources, and the long-term impact on the community. The Capital Improvement Plan identifies the city’s infrastructure, development objectives and allocation of financial resources. The 2019-2023 Capital Improvement Plan represents an excellent planning tool and provides for approximately $35.1 million of infrastructure improvements and assets during the next five years. While the improvements in the proposed Capital Improvement Plan are not "written in stone", they do provide a framework for allocating personnel and finances. The total project costs used in the CIP are rough estimates using 2018 dollar amounts, which will be refined during the budget, feasibility study and bidding process for each project. The improvement projects outlined in the CIP are designed to meet the city’s infrastructure needs and provide a safe environment for the community. Respectfully submitted, Ryan E. Ruzek, P.E.

The CIP includes detailed descriptions of improvement projects the city anticipates to initiate during the five-year period. The CIP is updated annually to ensure consistency and the reflection of changing demands and financial resources. CIP Goals The goals of the CIP are to: o Provide a balanced program for improvements given anticipated funding revenues over a five-year planning period. o Enable the Mendota Heights City Council to evaluate the needs of the entire city objectively. o Anticipate needed improvements in advance, rather than being overlooked until critically needed. o Provide a plan for improvements that can be used in preparing the budget for the coming fiscal year. Project Financing The 2019-2023 Capital Improvement Plan which is detailed on the following pages is financed from a variety of sources. The purpose of this section is to describe and analyze these sources, in as much detail as possible, so that the users of this CIP can be certain that the program as outlined can be financed from available funding sources. Municipal State Aid (MSA) Fund The Minnesota Department of Transportation (MnDOT) provides funding assistance for improvements to those municipal streets which are designated as part of its MSA system. The City of Mendota Heights receives an annual allotment of approximately $452,000 from the State of Minnesota Municipal State Aid Street Construction Account. The Municipal State Aid rules allow cities, subject to MnDOT approval, to request advanced funding for municipal state aid eligible projects from any municipal state aid funds available, provided that the amount of the advances do not exceed the city’s total estimated apportionment for the three years following the advance. Sanitary Sewer Utility Fund This fund receives revenue from the utility billing for sanitary sewer. It also is responsible for any expenses relating to the sanitary sewer system. Storm Water Utility Fund This fund receives revenue from the utility billings and is responsible for the expenses related to maintaining the city’s storm water system. Water Revenue Fund This fund accumulates the water surcharges the city receives from St Paul Regional Water Services. These funds are used for any city expenses that are incurred relating to the city’s water system and water tower. Special Assessments The City of Mendota Heights Street Rehabilitation and Reconstruction Assessment Policy approved in June 1992 states that the city will be responsible for financing up to 50% of street reconstruction and rehabilitation projects with the property owner being assessed for the remaining. City Funding (Municipal Bond Sales) Since it often takes several years for the city to collect special assessments, the city typically issues bonds for the remaining improvement costs for cash flow purposes. The bond payments relating to street improvement projects are then levied. If there are project costs relating to the above mentioned fund sources, the amount of bonds to be issued can be reduced by monies received from any of those funds. Special Park Fund This fund receives revenue from the Park Dedication fees. It also is responsible for expenses relating to new improvements to the Park system. City of Mendota Heights 2019 – 2023 Street Improvement Plan SIP OVERVIEW Street Improvement Plan (SIP) The Street Improvement Plan (SIP) is a planning tool that forecasts the city’s needs over a five year period based on city-adopted long-range plans, goals and policies. The SIP includes detailed descriptions of street improvement projects the city anticipates to initiate during the five-year period. The SIP is updated annually to ensure consistency and the reflection of changing demands and financial resources. SIP Goals The goals of the SIP are to: o Provide a balanced program for street improvements given anticipated funding revenues over a five-year planning period. o Enable the Mendota Heights City Council to evaluate the needs of the entire city objectively. o Anticipate needed street improvements in advance, rather than being overlooked until critically needed. o Provide a plan for street improvements that can be used in preparing the budget for the coming fiscal year. Project Details The street improvement projects being reported in the SIP will be shown within the following sections: o Street Reconstruction o Street Rehabilitation o Municipal State Aid o Preventative Maintenance Street Reconstruction A street reconstruction project will be defined as a project whereby many or all meaningful elements of an existing street are being removed and replaced. This would include curb and gutter, trails, bituminous or concrete pavement, aggregate base and items appurtenant to these elements. There are approximately 2 miles of streets in the City of Mendota Heights that have no curb and gutter. It has been the policy of the city that streets will be reconstructed with curb & gutter to maximize the life of the pavement surface, promote a uniform and standard appearance across the city, increase public safety, increase the efficiency of snow removal, and to capture and treat storm water prior to discharging into area water bodies. Typically, the City of Mendota Heights completes one street reconstruction project a year. Page 1 Street Rehabilitation A street rehabilitation project will be defined as a project in which one or more of the meaningful elements are modified or supplemented in-place, to restore the serviceability of the existing street (i.e. bituminous overlays or pavement replacement). The City of Mendota Heights maintains approximately 71.5 miles of public streets. As the street infrastructure ages, it requires preservation/rehabilitation to protect or extend its useful life. If the street infrastructure is not preserved, it will deteriorate prematurely and its benefit to the community will be lost. In addition, reconstruction costs are frequently four to five times the cost of preservation/rehabilitation and maintenance. As a result, the SIP reflects the broad direction of the City Council to preserve existing streets and infrastructure before they fall into such disrepair that expensive reconstruction is required. Municipal State Aid (MSA) The Minnesota Department of Transportation (MnDOT) provides funding assistance for improvements to those municipal streets which are designated as part of its MSA system. Money for this fund is supplied with a dedicated portion of revenues collected from road use and gasoline taxes. Funds are released for improvements on those streets on the system whose design and construction meet MSA standards. Funds may be expended for any street on the MSA system at any time, and MSA funds may be accumulated over several years. The City of Mendota Heights maintains approximately 15.1 miles of streets that are designated Minnesota State Aid (MSA). Preventative Maintenance Preventative maintenance includes activities such as snow removal, crack sealing, seal coating, street patching, street striping and street sweeping. Street maintenance activities are funded through the city’s general fund. Street Sweeping Street sweeping provides two primary benefits to the city. The more obvious benefit is the collection and removal of paper, leaves, and other visible debris that collect in the gutters. In addition to being unsightly, this debris can block the catch basins and other storm water facilities, causing localized flooding during heavy rains. An equally important, but less visible benefit is the removal of pollutants and other hazardous waste products left by passing vehicles. Although they are virtually invisible, these particles can be extremely harmful to the fish and other wildlife, if they reach our creeks and lakes. Bi-annual sweeping is recommended for storm water quality. Street crack sealing and seal coating Seal coating is the process of distributing bituminous oil, or liquid asphalt, on the street surface and then covering it with small rock chips. After the rock has been allowed to work into the oil, the excess rock is swept up and the seal coat provides the street with a new water proof surface and uniform look. Prior to seal coating, the city cleans and fills pot holes and cracks, and thoroughly sweeps the streets. Page 2 There are two main reasons for seal coating streets. The first reason to seal coat streets is to seal the bituminous surface against the elements. The older that a bituminous surface gets, the more porous it becomes. This is due to the wearing away of the surface due to sunlight, rain, snow, ice and traffic. As the bituminous surface becomes more porous due to these factors, it becomes more vulnerable to deterioration, and can form potholes. Potholes are formed when water seeps into the cracked pavement, expands and displaces the ground under the bituminous pavement. As the temperatures rise, the ground returns to normal but the pavement often remains raised creating a gap. When a vehicle drives over the raised pavement and gap, the pavement surface cracks and falls into the hollow space leading to a pothole. One method of avoiding this result is to routinely seal coat the streets to keep the water out. Streets are recommended to be seal coated 5 years after their initial construction or reconstruction and then again 13 years after their construction or reconstruction. The second reason to seal coat streets with a hard material like granite is to coat the surface with a wear resistant material. This not only minimizes damage done by normal traffic wear, but it also protects our streets from damage that might be done by routine snowplowing. Consequently seal coating does not add strength to the street; therefore, it is not used on older streets that need other type of repair such as overlaying or total reconstruction. Page 3 Project Financing The 2019-2023 Street Improvement Plan which is detailed on the following pages is financed from a variety of sources. The purpose of this section is to describe and analyze these sources, in as much detail as possible, so that the users of this SIP can be certain that the program as outlined can be financed from available funding sources. Transportation Facilities Improvements totaling approximately $16.8 million are planned for the 2019-2023 SIP.

This will extend the time frame when a costly street reconstruction project will be necessary. The sealing of cracks in the street surface reduces/eliminates water from entering the road base and subgrade. This process reduces the freeze/thaw cycles of the subgrade, maintaining the integrity of the road. Crack sealing is completed in a particular area one year prior to seal coating. This allows the crack sealing material to cure and minimize bleed through once seal coated. Seal coating will extend the useful life of roads by protecting the bituminous from oxidation due to adverse weather conditions (sun, rain, wind, snow, etc.). The prevention of oxidation will prolong the useful life of the pavement and defer the need for a costly reconstruction. Seal coating also improves the skid resistance of the roadway surface by increasing the friction between vehicle tires and the roadway. Streets that are reconstructed or rehabilitated are typically seal coated five years after they are paved. Each year, staff will determine an area that can be crack sealed and seal coated within the allotted budget based upon current estimated project costs. The areas tentatively planned for crack sealing and seal coating is shown on the map of seal coating projects.

Additional Striping is also accomplished when part of a street reconstruction project. Typically, pavement markings last 3-5 years before restriping is needed to maintain its reflectivity. Each year, staff will determine which streets in the city should receive restriping within the allotted budget. This includes centerline striping and shoulder striping. Striping enhances the safety of the roadway by maintaining reflectivity and by directing traffic to the correct lane movement.

Street sweeping reduces the pollutant load (leaves, pet/animal debris, heavy metals, oils, grease, sediment, etc.) to the receiving waters. In addition, material removed by street sweeping will not be able to block lines reducing the amount of flooding during heavy rainfall. Leaves in the street also are a safety problem, especially when wet. The street sweeping on city streets is conducted each spring and fall. Street Sweeping enhances the safety of the roadway by removing debris. Studies have shown that street sweeping is one of the most effective methods of reducing pollutants into water bodies. The city should consider additional sweeping as a Best Management Practice (BMP) to improve water quality. CITY OF l\1ENDOTA HEIGHTS STREET REHABILITATION AND RECONSTRUCTION POLICY PURPOSE The City of Mendota Heights Street Rehabilitation and Reconstruction policy is intended to provide a plan for maintaining the City's existing streets, and encourage the upgrade of rural streets to urban design. This document sets forth the methods and policies relating to local street improvements and special assessments practiced in the City of Mendota Heights. It is emphasized that the following summary is general in nature and that certain circumstances may justify deviations from stated policy as determined by the Mendota Heights City Council in its discretion. This policy may also be amended from time to time by vote of City Council. SECTION I DEFINITIONS 1. RECONSTRUCTION -will be defmed as a project whereby many or all meaningful elements of an existing street are being removed and replaced. This would include curb and gutter, sidewalks, bituminous or concrete pavement, granular base and items appurtenant to these elements. 2. REHABll..ITATION -will be defmed as a project in which one or more of the aforementioned elements is modified or supplemented in-place, to restore the serviceability of the existing street (i.e. bituminous overlays). 3. PREVENTIVE MAINTENANCE -will be defmed as work that involves a level of effort less than that involved in reconstruction or rehabilitation, the extent of which is to extend the life of the existing improvement. Preventive maintenance will include but not be limited to crack filling, patching, and seal coating. 4. RURAL STREET -any street that has no curb and gutter or storm sewer, or does not otherwise meet City design standards for thickness and width. 5. URBAN STREET - a street that has curb and gutter, storm sewer, and is designed to City standards for thickness and width. 1 SECTIONll GENERAL POLICIES AND PROCEDURES The following are general principles, policies and procedures applicable to all types of improvement: 1. Project costs shall include the cost of all necessary construction work required to accomplish the improvement, plus engineering, legal, fmancing, easement acquisition and contingency costs. 2. Assessable costs are project costs minus the City and County share and other credits. MSA funds will not be credited to offset assessments as they will be utilized in a revenue pool fund to offset total reconstruction program costs. 3. Special assessments will be levied as soon as practical. Normally this will be within one year after completion of the project. 4. Publicly owned properties, including but not limited to municipal building sites, schools, parks, County, State and Federal building sites, but not including public streets and alleys, are regarded as being assessable on the same basis as if such property were privately owned. 5. Revenue sources for these types of improvements will be many, including, but not limited to assessments, MSA Funds, infrastructure replacement funds and general tax levies. SECTIONll SPECIFIC POLICIES Project Initiation and Hearine Process This section describes the initiation of improvement projects and the administration required to receive fmal City Council action, pursuant to the requirements of Minnesota Statutes Chapter 429. A. Project Initiation 1. By Petition: Citizen petitions for initiating improvement will be prepared by City staff upon request. Such petitions circulated by the affected property owners should bear the signatures of the property owners of 51 % or more, of the benefitted property(ies). , . 2 When projects are initiated through this process the costs of doing engineering feasibility studies and associated project consideration costs will be borne by the property owner(s) so petitioning. If the project proceeds through construction and assessment those costs will be considered project costs under Section n.1 above. If the project does not proceed through construction these costs will be billed back to the property owners petitioning or will be recorded for future project costs consideration at which time the project is concluded. Determination of the method of cost recovery will be made by the City Council. 2. By Council Action~ If the Council determines that an improvement is in the best interest of the City, it can, without petition, initiate the improvement with a four/fIfths vote of the Council. The Engineering Department shall inventory and rate the condition of streets in the City. This rating shall then be used to determine the priority of street improvements in the City's 5 Year Street Improvement Plan. The City will generally improve streets that have the highest priority first. B. Hearing Process 1. Improvement Hearing: After a petition is fIled and its adequacy determined, or the Council initiates the project, the City Engineer is directed to study and report as to the feasibility of the improvement. If after reviewing the feasibility report, the Council feels the project has merit, a public hearing is scheduled, notice published twice, and persons benefitted by the project notified in writing in accordance with applicable State Statutes and City Standards. If after. the improvement hearing, at which all persons are heard, the Council feels that the project still has merit, then the Council will authorize the preparation of necessary plans and specifications, and upon receipt and acceptance of those plans, will authorize the advertisement for bids, by resolution, for the construction of the project. C. Determining Assessment Method to Use 1. Front Footage Assessment -The front footage assessment method will generally be used on all multiple land use projects as per the City's adopted assessment policy. That is, if an improvement project affects parcels that are not zoned similarly the front footage method will generally be used. 3 2. Unit Assessment -Where a project affects parcels which are all zoned similarly or part of a multi-unit development, the Unit Assessment method may be applied. 3. Area Assessment -Area assessment may be used for storm sewer improvements. This may be necessary for projects where the stonn sewer is installed for reasons other than just elimination of ditches. If necessary or desirable to achieve equitable distribution of assessments, the City Council may adopt alternative methods for calculating assessments consistent with the City's adopted assessment policy. D. Amount of Assessments 1. Rehabilitated Rural Streets -Rural streets that are rehabilitated or are reconstructed as a rural section shall be . fmanced 100% through assessments to the abutting properties. As rural street sections are not considered desirable, no City funding assistance shall be available. 2. Upgraded Rural Streets -It is the City desire to upgrade rural street sections to urban street sections where possible. Therefore when a rural street is scheduled for an improvement, upgrading to urban design will be the objective unless otherwise detennined by the City Council. In making such a determination the City Council may consider a petition from property owners to perpetuate a rural street. The City will fmance up to 50 % of the total project cost through the Infrastructure Replacement Fund for an upgrade project. The affected property owners will be assessed the cost of the storm sewer pipe, the new curb, and a portion of the street reconstruction cost. 3. Rehabilitated Urban Streets -For streets that are urban design, the City shall finance 50 % of rehabilitation costs. 4. Reconstructed Urban Streets -When an urban street is reconstructed all of the reconstruction costs shall be assessed to the abutting property owners. The City will fmance 50 % of that portion of the project that could be classified as rehabilitation (the fmaIlift of blacktop). 5. Preventive Maintenance -The City shall perform routine and regular preventative maintenance to the extent practical on all streets in the City, until such time as the street has aged or deteriorated to the extent that such maintenance is no longer cost effective. 4 When a street has reached its expected life, in accordance with the City's infrastructure rating system, no additional preventative maintenance shall be performed. The only work performed will be the minimum amount necessary to keep the street reasonably safe for vehicular traffic. All preventative maintenance shall be funded by the City for streets where preventative maintenance is cost effective. On deteriorated streets, no preventative maintenance shall be performed except at the sole expense and request of the adjoining property owners E. Period of Assessments Assessments shall be spread over the life of the project. The expected life of various projects to be used in levying assessments is presented here: Project Type Rural Rehabilitation Rural Reconstruction as Rural Rural Reconstruction as Urban Urban Rehabilitation Urban Reconstruction SECTION IV CONSTRUCTION STANDARDS Minimum Desiz:n Standards 10 years 10 years 20 years 10 years 20 years The following are minimum design standards applied to the design and construction of improvements in the City of Mendota Heights and are for reference to this policy. A. Storm Sewer System Lateral pipe and catch basin size shall be generally be designed to handle a 10 year event and trunk facilities shall generally be designed to handle a 100 year event as determined by the City Engineer. B. Sidewalks, Trails and Bikeways Concrete -5' wide with 6" sand base -4" thick Bituminous -8' wide (2341) Bit. with 6" Class 5, 100 percent crushed rock and 2" Bituminous 5 All trails and sidewalks will be located 1 0 off property line if at all possible, pedestrian ramps and curb drops will be installed according to MN/DOT Standards. C. Streets Urban streets shall be classified as either local or collector streets. Urban local streets shall normally be 33 feet wide, face to face, and 7 ton design, curb and gutter on local streets shall be B618. Collector streets shall be 9 ton design and shall normally be constructed to Municipal State Aid (MSA) standards. Rural streets are not desirable. Therefore for any rural street reconstruction project the City shall proceed as if the rural street is to be upgraded to urban design. Unless a neighborhood opposes this upgrade, it shall occur. Rural streets that are not upgraded will generally be rehabilitated via an overlay of 1.5"-2" of blacktop. SECTION V ASSESSMENT DEFERRAL POLICY Deferral of Special Assessments A. Purpose -To indicate in certain instances the City may allow deferral of special assessments levied under this policy. B. Conditions of Deferral: Application for deferral of special assessments under these provisions must be fIled within thirty (30) days from the date the assessment roll is adopted. Applications granted shall continue in effect for subsequent years until the property no longer qualifies. Applications shall be filed with the assessor of the taxing district in which the real property is located. C. Situations of Discretionary Deferral: 1. Senior citizen/low income deferral. At its discretion the City may defer assessments against any homestead property owned by a person 65 years of age or older or retired by virtue of a permanent and total disability and for whom it would be a hardship to make the assessment payments. The standards and guidelines governing what constitutes hardship are established by City ordinance or resolution. 6 Additionally, the City may grant a deferral in situations where its hardships standards and guidelines have not been met if exceptional and unusual circumstances exist and no preference or discriminatory treatment will occur. This deferral is subject to the provisions of Minnesota Statutes 435.193. 2. Unimproved property deferral. The City may also defer the assessments of improvements with respect to property which is not directly and immediately affected by the improvement for which the assessment is levied. If applicable, at such times as extensions or connections regarding the improvement directly benefit such unimproved property, the City may require payment of the deferred assessments as well as those relating to the connection or extension. This deferral is subject to the provisions of Minnesota Statutes 429.051. Any such deferral shall be subject to such other terms and conditions including accrual of interest, and shall be subject to termination, all as determined by City Council. Adopted by the Mendota Heights City Council this 16th day of June 1992. CITY COUNCIL CITY OF MENDOTA HEIGHTS By:------=-~_ .... _~_~_r _~ __ _ Charles E. Mertensotto, Mayor ATTEST: KHE:dfw 2019 – 2023 Sanitary Sewer Improvement and Maintenance Plan City of Mendota Heights OVERVIEW OF SANITARY SEWER SYSTEM Sanitary Sewer Collection System The City of Mendota Heights sanitary sewer collection system is available to the majority of existing land uses. Almost 100 percent of Mendota Heights current population is connected to the sanitary sewer collection system with the exception of a limited number of scattered sites that still utilize Individual Sewage Treatment Systems (ISTS) which are private on-site septic systems. Wastewater from the City of Mendota Heights is collected and conveyed to the wastewater treatment plant through a network of over 79.1 miles of gravity sewers, 2.6 miles of pressure sewer (force main), 2,067 sanitary manholes and 6 lift stations. The City of Mendota Heights is completely within the Metropolitan Urban Service Area (MUSA). The sanitary sewage system in Mendota Heights was developed based upon the Sanitary Sewer System Master Plan dated March 28, 1966. In 1972, the Sanitary Sewer Master Plan was approved by the Metropolitan Council (formerly the Metropolitan Sewer Board and Metropolitan Waste Control Commission). The City of Mendota Heights is serviced by the Metropolitan Council waste water system managed by Metropolitan Council Environmental Services (MCES). The sanitary sewerage collection system in Mendota Heights is a tributary to the Metropolitan Council system. The majority of the Mendota Heights system flows into a Metropolitan Council sewer interceptor connection, which crosses under the Mississippi River near the Interstate 35E Bridge to the West Seventh Street interceptor and ultimately to the treatment plant at Pig’s Eye Island. A portion of the northeastern part of the City flows directly into the St. Paul system at Chippewa Avenue and Annapolis Street. Individual Sewage Treatment Systems (ISTS) Approximately 45 Individual Sewage Treatment Systems (ISTS) are still utilized in Mendota Heights. The largest concentrations of on-site septic systems are in the Super Block neighborhood located in the east central part of the City, adjacent to the City of West St. Paul and the Olivia T. Dodge Nature Center. City Code (10-3-3: Individual Sewage Treatment Systems) outlines management practices for properties served by an Individual Sewer Treatment System (ISTS):  The system must be pumped/inspected at least once every three years.  The Pumping/Inspection must be performed by a person with a current MPCA sewage contractor license.  The licensed contractor is responsible for filing a septic maintenance log with Dakota County.  Upon verification of required maintenance, the City shall issue a statement of compliance in letter form, permitting three additional years of operation.  The City will notify the owner of an ISTS no later than two months before permit expiration. The City has contracted Dakota County to perform this work. Individual Service Connections The City of Mendota Heights is not responsible for the cleaning, maintaining, or repairing individual service connections from their building up to and including the connection to the sanitary sewer main; the property owner bears the responsibility. Sanitary sewer system regulations, ordinances and management practices The City of Mendota Heights has adopted a number of practices that are aimed at protecting the quality of water resources within Mendota Heights and the integrity of the sanitary sewer system. These practices are crucial to the future performance and investment required by the utility system because they represent the manner in which this and previous sanitary sewer plans are implemented.  The sanitary sewer ordinance prescribes the design and manner in which individual connections and use of public sewers are to be made. To limit the amount of inflow into the sanitary sewer system, the ordinance prohibits the flows of storm water, ground water, roof runoff, surface water, unpolluted drainage, unpolluted industrial cooling water, or unpolluted industrial process water into any public sanitary sewer.  The city zoning regulations determine the specific use and development intensity of individual parcels in the community.  The city subdivision ordinance requires that properties to be developed be served by the municipal sanitary sewer system, and that, all new sanitary sewers must be constructed according to plans approved by the Public Works Director.  The construction of the municipal and MCES sanitary sewer systems and their on-going operations are financed by: Service Availability Charges (SAC), assessments to properties, and by customer charges that are paid on a regular basis.  The City of Mendota Heights has updated its on-site septic system ordinance to comply with Minnesota Pollution Control Agency (MPCA) requirements.  The Mendota Heights Public Works Department Utilities Division is responsible for all maintenance activities associated with the sanitary sewer system. Existing system issues Basic problems that can affect the operation of a sewer collection system include infiltration, inflow, and blockages. It is important that infiltration and inflow flows be kept to a minimum to maintain pipe capacity and preserve treatment plant capacity. The most common sources of sewer blockages are tree root obstructions, and solids settling out and collecting within the sanitary sewer collection system as a result of sewer lines flowing at less than design capacity. Inflow and Infiltration The condition of sanitary sewer systems can greatly impact total sewage flow. Inflow and Infiltration (I/I) are terms for the ways that clear water (rain and groundwater) makes its way into sanitary sewer pipes. Infiltration occurs when groundwater seeps into sewer pipes through cracks, leaky joints or deteriorated manholes. Inflow is a direct connection that allows rainwater to enter the sewer system through roof leaders, basement sump pumps, or foundation drains illegally connected to the system. I/I are of great concern as it results in the unnecessary treatment of water and consumes capacity in the large regional sewer pipes. I/I can also contribute to sewer backups into homes and overflows into local lakes and rivers. In order to minimize I/I, the City of Mendota Heights prohibits the connection of sump pumps, rain leaders and passive drain tile into the sanitary sewer system. The current I/I goal for the City of Mendota Heights is an allowable peak hourly flow of 4.83 MGD with an adjusted average of 1.67 MGD. In 2016, The city began an inspection of the city to find, and ultimately eliminate, residential sump pump connections to the city sewer system. Eliminating these connections will reduce the amount of storm drainage into the sanitary sewer. SSIMP OVERVIEW Sanitary Sewer Improvement and Maintenance Plan (SSIMP) The Sanitary Sewer Improvement and Maintenance Plan (SSIMP) is a planning tool that forecasts the city’s needs over a five year period based on city-adopted long-range plans, goals and policies. The SSIMP includes detailed descriptions of sanitary sewer improvement projects and maintenance projects the city anticipates to initiate during the five-year period. The SSIMP is updated annually to ensure consistency and the reflection of changing demands and financial resources. SSIMP Goals The goals of the SSIMP are to: o Provide a balanced program for sanitary sewer improvements given anticipated funding revenues over a five-year planning period. o Enable the Mendota Heights City Council to evaluate the needs of the entire city objectively. o Anticipate needed sanitary sewer improvements in advance, rather than being overlooked until critically needed. o Provide a plan for sanitary sewer improvements that can be used in preparing the budget for the coming fiscal year. Project Details The sanitary sewer improvement projects being reported in the SSIMP will be shown within the following sections: o Preventative Maintenance o Sanitary Sewer Rehabilitation Preventative Maintenance Preventative maintenance includes activities such as cleaning and televising sanitary sewer lines, visual inspection of manholes, annual inspection and maintenance of lift stations, and root cutting in the main lines. Sanitary sewer maintenance and activities are funded through the Sanitary Sewer Utility Fund. Cleaning and Televising In 2006, the City of Mendota Heights started a cleaning and televising program with the goal of cleaning and televising the entire sanitary sewer system in a 5 year period. Currently, Public Works Staff along with one seasonal employee clean approximately 7-10 miles of pipe per year. In addition, the city hires a contractor each year to clean an additional 7-8 miles of pipe and televise all of the pipes that are cleaned that year. At our current rate, the city is cleaning and televising the entire sanitary sewer system every 5-6 years. Sanitary sewer pipes are cleaned and televised to identify problem areas, including leaking joints, collapsed sections of pipe and excessive root intrusion through cracks and joints. Excessive root intrusion can cause plugging, which can lead to sewage backups into basements. Through routine televising and maintenance logs, Public Works staff have identified and prioritized those sections of sewers that require disproportionate maintenance to remain functional or have a history of excessive root intrusion. The SSIMP was then developed to address these problem areas using a variety of rehabilitation techniques, including: conventional excavation and pipe replacement; pipe lining with cured-in-place pipe (CIPP); additional root treatments. CIPP installation involves inverting an epoxy saturated fiber lining into a sewer line and using water/stream pressure to cure the epoxy. Services and lateral connections are opened after the pipe has cured using a camera and robotic cutter. This process results in a continuous, joint free, structural liner that can be installed with minimal disruption to adjacent residents and traffic, and requires no excavation or street reconstruction. Sanitary Sewer Rehabilitation A sanitary sewer rehabilitation project will be defined as a project in which the sanitary sewer is modified or supplemented in-place, to restore the serviceability of the existing sanitary sewer system. The City of Mendota Heights maintains approximately 81.7 miles of sanitary sewer pipe. As the sanitary sewer infrastructure ages, it requires rehabilitation to protect or extend its useful life. If the sanitary sewer infrastructure is not preserved, it will deteriorate prematurely and its benefit to the community will be lost. As a result, the SSIMP reflects the broad direction of the City Council to preserve existing sanitary sewer infrastructure before they fall into such disrepair that expensive reconstruction is required. Typically, the City of Mendota Heights completes one sanitary sewer lining project a year and additional sanitary sewer rehabilitation projects as needed. Reconstruction projects are identified and planned as part of the Street Improvement Plan (SIP) as sanitary sewer reconstruction often involves removal of the road surface for utility access. Sanitary sewer reconstruction projects that do not impact streets are identified in this plan. Sanitary Sewer Facilities Improvements totaling approximately $4 million are planned for in the 2019-2023 SSIMP. Highlights of the planned projects are as follows: Preventative Maintenance Projects: Annual Sanitary Sewer Cleaning and Televising Sanitary Sewer Rehabilitation Projects: Annual Sanitary Sewer Lining Sanitary Sewer Replacement Projects: 2019: 816 Ridge Place Sanitary Sewer Rehabilitation Sanitary Sewer Utility Fund Summary Improvement Projects SANITARY SEWER IMPROVEMENT & MAINTENANCE PLAN 2019-2023 CITY OF MENDOTA HEIGHTS SANITARY SEWER UTILITY FUND SUMMARY Available Balance (12/31/2017)$87,000 Revenue 2018 2019 2020 2021 2022 2023 Cash Balance $87,000 $226,000 $83,000 $51,000 $288,000 $560,000 Estimated Annual Sanitary Sewer Revenue $2,084,000 $2,292,000 $2,407,000 $2,527,000 $2,653,000 $2,786,000 Total Revenue $2,171,000 $2,518,000 $2,490,000 $2,578,000 $2,941,000 $3,346,000 Expenditures 2018 2019 2020 2021 2022 2023 Estimated MCES Sewer Fees $1,343,000 $1,410,000 $1,481,000 $1,555,000 $1,633,000 $1,715,000 Estimated City Operational Costs $430,000 $448,000 $646,000 $423,000 $436,000 $449,000 Annual Sanitary Sewer Cleaning and Televising $62,000 $62,000 $62,000 $62,000 $62,000 $62,000 Annual Sanitary Sewer Lining $200,000 $200,000 $250,000 $250,000 $250,000 $250,000 Lift Station Rehabilitation $0 $0 $0 $0 $0 $0 816 Ridge Place Sanitary Sewer Rehabilitation $0 $315,000 $0 $0 $0 $0 Total Expenditures $2,035,000 $2,435,000 $2,439,000 $2,290,000 $2,381,000 $2,476,000 Total Unreserved Cash Balance on 12/31 $136,000 $83,000 $51,000 $560,000 $870,000 2019 Revenue includes an estimated $90,000 MCES grant 2019 Operation costs include $49,000 towards Public Works Improvements (Fence, Salt Bin) 2020 Operation costs includes $235,000 for replacement of Water Jet Truck (1991) $288,000 SANITARY SEWER IMPROVEMENT & MAINTENANCE PLAN 2019-2023 CITY OF MENDOTA HEIGHTS PROJECT NAME: Annual Sanitary Sewer Cleaning and Televising TOTAL COST: $310,000 PROJECT #: 501 PROJECT TYPE:Sanitary Sewer PM Project Description Project Location Project Justification Project History Project Costs 2019 2020 2021 2022 2023 Total Planning/Design $0 Construction/Maintenance $62,000 $62,000 $62,000 $62,000 $62,000 $310,000 Total $62,000 $62,000 $62,000 $62,000 $62,000 $310,000 Funding Sources 2019 2020 2021 2022 2023 Total Municipal Bond Sales $0 Municipal State Aid Fund $0 Other Government Unit Funding $0 Sanitary Sewer Utility Fund $62,000 $62,000 $62,000 $62,000 $62,000 $310,000 Special Assessments $0 Storm Water Utility Fund $0 Water Revenue Fund $0 Total $62,000 $62,000 $62,000 $62,000 $62,000 $310,000 Each year, staff will determine the sanitary sewer that can be cleaned and televised within the allotted budget based upon current estimated project costs. The areas tentatively planned for cleaning and televising are shown on the sanitary sewer cleaning and televising map. The City of Mendota Heights maintains 81.7 miles of sanitary sewer pipe. In 2006, the City of Mendota Heights started a cleaning and televising program with the goal of cleaning the entire sanitary sewer system in a 5 year period. Currently, Public Works staff along with one seasonal employee cleans approximately 7-10 miles of pipe per year. In addition, the city hires a contractor each year to clean an additional 7-8 miles of pipe and televise all of the pipes that are cleaned that year. At the current rate, the entire sanitary sewer system is cleaned every 5-6 years. Mendota Heights sanitary sewer system is aging. Many of its pipes are 60 years old and will soon be in need of repair. Cleaning the sewer system on a regular cycle will help extend the life of the pipes. Televising of the system will show where immediate repairs are needed.

SWIMP OVERVIEW Storm Water Improvement and Maintenance Plan (SWIMP) The Storm Water Improvement and Maintenance Plan (SWIMP) is a planning tool that forecasts the city’s needs over a five year period based on city-adopted long-range plans, goals and policies. The SWIMP includes detailed descriptions of storm sewer and pond improvement projects and maintenance projects the city anticipates to initiate during the five-year period. The SWIMP is updated annually to ensure consistency and the reflection of changing demands and financial resources. SWIMP Goals The goals of the SWIMP are to: o Provide a balanced program for storm water and pond improvements given anticipated funding revenues over a five-year planning period. o Enable the Mendota Heights City Council to evaluate the needs of the entire city objectively. o Anticipate needed storm water improvements in advance, rather than being overlooked until critically needed. o Provide a plan for storm water improvements that can be used in preparing the budget for the coming fiscal year. Project Details The storm water improvement projects being reported in the SWIMP will be shown within the following sections: o Storm Sewer Maintenance and Improvements o Pond Maintenance o Streambank Stabilization Storm Water Facilities Storm Water improvements totaling approximately $2.3 million are planned for in the 2019-2023 SWIMP.

space, and trail system with 15 city parks. In 1989, a voter approved park referendum was passed which funded upgrading 8 existing neighborhood parks, constructing 5 new parks, and constructing 7.8 miles of trails. In addition to city parks, the City purchased the 17-acre Mendota Heights Par 3 Golf Course by a separate referendum in 2007. The City also joined with other public entities and purchased the 25.5-acre Historic Pilot Knob site in 2006/2007, which will be retained as open space. Park and trail facilities maintained by others located within or near the city boundaries are Fort Snelling State Park, Harriet Island-Lilydale Regional Park, Dodge Nature Center, Big Rivers Regional Trail, and North Urban Regional Trail, renamed the River to River Greenway (Mendota-Kaposia Trail). Park Improvement and Maintenance Plan (PIMP) The Park Improvement and Maintenance Plan (PIMP) is a planning tool that forecasts the city’s needs over a five year period based on city-adopted long-range plans, goals and policies. The PIMP includes detailed descriptions of park improvement projects and maintenance projects the city anticipates to initiate during the five-year period. The PIMP is updated annually to ensure consistency and the reflection of changing demands and financial resources. PIMP Goals The goals of the PIMP are to: o Provide a balanced program for park improvements given anticipated funding revenues over a five-year planning period. o Enable the Mendota Heights City Council to evaluate the needs of the entire city objectively. o Anticipate needed park improvements in advance, rather than being overlooked until critically needed. o Provide a plan for park improvements that can be used in preparing the budget for the coming fiscal year. Park Facilities Park improvements totaling approximately $2.4 million are planned for in the 2019-2023 PIMP.

DATE: January 4, 2015 TO: Mayor and City Council FROM: Sloan Wallgren, Recreation Program Coordinator SUBJECT: Declaring the City of Mendota Heights a Pollinator-Friendly City Background The Parks and Recreation Commission is consistently looking for ways to improve the Mendota Heights community and parks. Recent research has shown that the pollinator population is declining nationwide due to the loss of basic habitat, the simplification of landscapes, and the increased use of neonicotinoid systemic insecticides. It is important to participate in pollinator- friendly practices, because pollinators are a necessary component to a healthy ecosystem. At the October 13, 2015 Parks and Recreation Commission meeting, the commission passed a motion for the council to consider, which would declare Mendota Heights to be a Pollinator-Friendly City. It further outlined ways to help the desired result to become a reality. The following is a list of the actions steps the commission recommends for implemetation in order for the City of Mendota Heights to become a Pollinator-Friendly City: 1.The City would make sure that future plantings on city property are pollinator-friendly. 2.The City will include an article in the April 2016 issue of the Heights Highlights to educate the residents as to why it is important to be pollinator-friendly and how to become pollinator-friendly. 3.The City will provide links on the city’s website to pollinator-friendly websites, which will include best practices and a list of pollinator-friendly plants. 4.Individual members of the Commission would work to establish a plant sharing program. 5.The City will continue to work with Green River Greening to plant pollinator-friendly plants when the opportunity presents itself. 6.The City would continue to not use neonicotinoid systemic insecticides. Staff has attached a sample of the resolution and an example of the information that would be available on the City's website. Budget Impact There will be no impact to the budget. Recommendations Thew Parks and Recreation Commission recommends that the City Council adopt a resolution, declaring the City’s intent to become a Pollinator –Friendly community. CITY OF MENDOTA HEIGHTS DAKOTA COUNTY, MINNESOTA RESOLUTION 2016-01 RESOLUTION DECLARING THE CITY OF MENDOTA HEIGHTS TO BE A POLLINATOR-FRIENDLY COMMUNITY WHEREAS, bees and other pollinators are a necessary component of a healthy ecosystem and food system, providing pollination of plants in order to grow vegetables, herbs and fruits; and WHEREAS, pollinator populations are in sharp decline due to an ongoing loss of habitat as a result of human land practices, which is coupled with a simultaneous large-scale expansion of insecticide use by homeowners, landscapers, property managers and farmers; and WHEREAS, neonicotinoid and other systemic insecticides have been shown to cause illness and death to bees and pollinators; and WHEREAS, alternative land management practices are available that dramatically increase pollinator forage while decreasing maintenance costs; and WHEREAS, the monetary and social cost of maintaining pollinator-friendly landscapes can be less expensive the than costs associated with maintaining chemically- treated monocrop landscapes; and WHEREAS, many Mendota Heights residents and businesses are pledging to manage their land in a pollinator-friendly way; and WHEREAS, acting in a pollinator friendly manner is not expected to inhibit any potential treatments for Emerald Ash Borer infestation. NOW, THEREFORE, BE IT RESOLVED by the City Council of the City of Mendota Heights, Minnesota, that the City of Mendota Heights is hereby declared a Pollinator- Friendly Community, and that the City celebrates current policies and practices that protect and support pollinator health by minimizing the use of insecticides. BE IT FURTHER RESOLVED that the City of Mendota Heights urges all Mendota Heights property owners, residents, businesses, institutions and neighborhoods to become more pollinator-friendly by adopting practices including: -Committing to avoiding the use of insecticides, including systemic insecticides, on their property; -Avoiding the planting of flowering plants which are treated with systemic insecticides; -Planting more pollinator-supporting forage on their property, and adopting organic or chemical-free lawn and landscaping practices. Adopted by the City Council of the City of Mendota Heights this 5th day of January, 2016. Sandra Krebsbach, Mayor ATTEST: Lorri Smith, City Clerk page 2 of 2 2019 – 2023 Trail Improvement and Maintenance Plan City of Mendota Heights OVERVIEW OF TRAIL SYSTEM Park and Trail System The City of Mendota Heights provides 27.9 miles of city trails and on street connections (wide shoulders), 2.7 miles of county trails, 3.8 miles of MnDOT maintained on street connections, and 3.2 miles of privately owned and maintained sidewalks. In 1989, a voter-approved park referendum was passed which funded upgrading 8 existing neighborhood parks, constructing 5 new parks, and constructing 7.8 miles of trails. The City of Mendota Heights currently has sufficient park acreage to serve its residents, although not all residents have equal access to those facilities. Future improvements will focus on updating existing facilities and adding trail connections to neighborhoods that lack access to parks. Trails are an important component and are the focus of this plan because they connect neighborhoods to one another and the community to regional recreational opportunities. A comprehensive trail system also enhances alternative opportunities for transportation. Identified Trail Gaps Improved trail connections are important because many residential areas are divided by highways and arterial roads. The recent construction of the Big Rivers Regional Trail along the Minnesota River and the trail connection to the I-35E Bridge trailway have also heightened the awareness and demand for improved access to the river valley. Access to the Big Rivers Regional Trail is difficult due to the significant elevation changes. As a result, many areas of the community cannot be easily accessed on bikes, roller blades or foot from other areas of the community. Additional or improved trail connections create opportunities for alternative transportation and healthy living and are needed to provide residents access to City parks and other recreational opportunities in the region. Trail gaps and proposed connections/improvements planned by the City are shown on the existing trail system map and are listed below. Proposed Connection/Improvements (As identified in the Street Improvement Plan (SIP))  Dodd Road (Market Street to Wesley Lane) Identified Gaps  Mendota Heights Road (Highway 13 to Scenic Overlook)  Dodd Road (Wesley Lane to Marie Avenue)  Dodd Road (Marie Avenue to Delaware Avenue)  Lexington Avenue (Wagon Wheel to Tom Thumb) Page 1 TIMP OVERVIEW Trail Improvement and Maintenance Plan (TIMP) The Trail Improvement and Maintenance Plan (TIMP) is a planning tool that forecasts the city’s needs over a five year period based on city-adopted long-range plans, goals and policies. The TIMP includes detailed descriptions of trail improvement projects and maintenance projects the city anticipates to initiate during the five-year period. The TIMP is updated annually to ensure consistency and the reflection of changing demands and financial resources. TIMP Goals The goals of the TIMP are to: o Provide a balanced program for trail improvements given anticipated funding revenues over a five-year planning period. o Enable the Mendota Heights City Council to evaluate the needs of the entire city objectively. o Anticipate needed trail improvements in advance, rather than being overlooked until critically needed. o Provide a plan for trail improvements that can be used in preparing the budget for the coming fiscal year. Project Details The trail improvement projects being reported in the TIMP will be shown within the following sections: o Preventative Maintenance o Trail Rehabilitation o Trail Construction Preventative Maintenance Preventative maintenance activities that are performed on a continuous schedule are tasks such as trail sweeping, crack sealing, pothole patching, and spot repairs. Preventative maintenance activities that are performed on an as-needed basis are tasks such as snow and ice removal, drainage control, signage replacement, and graffiti control. Trail maintenance activities are funded through the Public Works Parks Department - Parks Maintenance Fund out of the General Fund Levy. Trail Sweeping Trail sweeping is an important aspect of trail maintenance, helping ensure trail user safety. Sweeping should be performed on a regular schedule. Crack Sealing, Pothole Patching and Spot Repairs Repair of bituminous trails should be closely tied to trail inspection and setting priorities for repairs. The time between observation and repair of a trail will depend on whether the needed repair is deemed a hazard, to what degree the needed repair will affect the safety Page 2 of the trail user, and whether the needed repair can be performed by the trail maintenance crew or if it is so extensive that it needs to be repaired by contracted services. Snow and Ice Removal The Mendota Heights trail system is open year round, requiring snow and ice removal. Removal of ice and snow is important for safety reasons and long term life expectancy of the trail system. Attention must be paid to those areas where there is a grade change and/or curves. Drainage Control In places where low spots on the trail catch water, trail surfaces should be raised, or drains built, to carry water away. Some trail drainage control can be achieved through the proper edging of trails. If trail drainage is corrected near steep slopes, the possibility of erosion must be considered. Signage Replacement Trail signs fall into two categories: safety and information. Trail users should be informed of their location, where they are going, and how to safely use trails. Signs related to safety are most important, thus they should receive the highest priority. Information signage can enhance the trail users experience and is prioritized behind safety signage. Graffiti Control The key to graffiti control is prompt observation and removal. Graffiti should be noted during trail inspections and the graffiti should be removed as soon as possible. Trail Rehabilitation A trail rehabilitation project will be defined as a project in which the trail is modified or supplemented in-place, to restore the serviceability of the existing trail. The City of Mendota Heights maintains approximately 27.9 miles of trails of which 26.2 miles are off-street trails maintained by the Parks Department and 1.7 miles are on-street connections (wide shoulders) maintained by the Street Department. As the trail infrastructure ages, it requires rehabilitation to protect or extend its useful life. If the trail infrastructure is not preserved, it will deteriorate prematurely and its benefit to the community will be lost. As a result, the TIMP reflects the broad direction of the City Council to preserve existing trail infrastructure before they fall into such disrepair that expensive reconstruction is required. Typically, the City of Mendota Heights completes trail rehabilitation projects in conjunction with nearby street improvement projects and as funding is available. Trail Construction A trail construction project will be defined as a project whereby many or all meaningful elements of a new trail (previously non-existent) are being constructed. Typically, the City of Mendota Heights completes new trail construction projects as funding is available. Page 3 Trail Facilities Trail improvements totaling approximately $1.0 million are planned for in the 2019-2023 TIMP.

Fleet maintenance is funded through respective department budgets. Fleet acquisition is generally accomplished using the tax levy, general fund or other associated fund (Utility, Special Park, etc.). Mendota Heights adopted a Fleet Safety Policy on August 20, 2013. An equipment fund was established in 2016. Over time, this fund will provide a more predictable source of funding for larger costs of capital equipment. Public Works, Engineering, and Administration Fleet improvements totaling approximately $1.1 million are planned for in the 2019-2023 Public Works, Engineering & Administration FLIMP. The current fleet practice is to maintain equipment for the following time frames: Pick Up Trucks, Skid Steer 10 years Plow Trucks 15 years Trailers 20 years Loader, Jetter, Generator 25+ years See summary sheets.

EXECUTIVE SUMMARY The purpose of this plan is to describe how the current Surface Water Management Plan when combined with the City policy and procedures meets statutory, rule, and Metropolitan Council requirements. The purpose of this Surface Water Management Plan is broad and the goal is to guide the City in managing its surface and groundwater resources. This will enable the City to develop drainage facilities in a cost-effective manner, while maintaining or improving the quality of its water resources. 1.1. Purposes The City of Mendota Heights’ Surface Water Management Plan (also referred to as the plan, SWMP, City plan, local plan) is a local management plan that meets the requirements of Minnesota Statutes 103B.235, Minnesota Rules 8410, the Lower Mississippi River Watershed Management Organization Third Generation Watershed Management Plan (dated August 2011, as amended August 2015) and the Lower Minnesota River Watershed District’s Third Generation Watershed Management Plan (dated November 2011, as amended June 2015). The purpose of the SWMP is to serve as a guide in conserving, protecting, and managing the City’s surface water resources. This plan is an update to the 2006 Local Surface Water Management Plan (LSWMP) and includes updates to the City’s HydroCAD Model as well as the incorporation of a P8 Urban Catchment water quality model. The City submits its SWMP to the Metropolitan Council, the Lower Mississippi River Watershed Management Organization, and the Lower Minnesota River Watershed District for their review. The watershed organizations have 60 days for their review after written receipt of the City SWMP. Metropolitan Council provides comments within 45 days. Metropolitan Council directs its comments to the watershed organizations which then consider these comments in formulating their own. 1.2. Surface Water Management Responsibilities and Related Agreements The City of Mendota Heights is party to two separate joint powers agreements related to surface water management: 1.With the cities of St. Paul, Lilydale, Mendota, Mendota Heights, Sunfish Lake, West St. Paul, South St. Paul, and Inver Grove Heights establishing the Lower Mississippi River Watershed Management Organization (LMRWMO). 2.With the cities of Bloomington, Burnsville, Carver, Chanhassen, Chaska, Eagan, Eden Prairie, Lilydale, Mendota, Mendota Heights, Minneapolis, Savage, and Shakopee establishing the Lower Minnesota River Watershed District (LMRWD). The City also has an agreement with both the LMRWMO and LMRWD establishing the City as the Local Government Unit for administering the Wetland Conservation Act (WCA) within the City. Upon approval of this SWMP by the two watersheds with jurisdiction over the City, it is the City’s intent to maintain its current permitting powers through its Permit for Land Disturbing Activities. Currently, the LMRWMO and LMRWD do not issue permits, so no impact to these organizations would occur. The watersheds would continue in their role as project review agencies. The City of Mendota Heights is responsible for construction, maintenance, and operation of the City's stormwater management systems (e.g., ponds, BMP, mechanical structures, sump manholes, pipes, channels) in accordance with its MS4 Permit. SECTION 1 Surface Water Management Plan Section 1 City of Mendota Heights WSB Project No. 1735-04 Page-2 1.3. Metropolitan Council Requirements Metropolitan Council’s 2040 Water Resources Management Plan expands upon the requirements of Rule 8410 as follows: 1. Communities must commit to a goal of no adverse impacts (non-degradation) for area water resources. 2. The assessment of problems and corrective actions must include Total Maximum Daily Load (TMDL) considerations. 3. Require infiltration of the first half inch of runoff from impervious areas created by projects where there are A and B soils. 4. Require infiltration in wellhead protection areas be based on City’s wellhead protection plan. 5. Communities with trout streams must identify actions to reduce thermal pollution. 6. Communities must meet state requirements for development near outstanding resource value waters. 7. Communities must consider stormwater management practices that promote infiltration and filtration including the reduction of impervious surface. 8. Include information of types of Best Management Practices (BMPs) used to improve stormwater quality and quantity including maintenance schedules. 1.4. Plan Structure The Mendota Heights SWMP is divided into six sections: x Section 1 Executive Summary provides background information and summarizes the plan contents. x Section 2 Land and Water Resource Inventory presents information about the topography, geology, groundwater, soils, land use, public utilities, surface waters, hydrologic system and data, and the drainage system. x Section 3 Agency Cooperation outlines other governmental controls and programs that affect stormwater management. x Section 4 Assessment of Problems and Issues presents the City's water management related problems and issues. x Section 5 Goals and Policies outlines the City's goals and policies pertaining to water management. x Section 6 Implementation Program presents the implementation program for the City, which includes defining responsibilities, prioritizing, and listing the program elements. 1.4.1. Background This report provides the City of Mendota Heights with a SWMP that serves as a guide to managing the City’s surface water system, and brings the City into compliance with Minnesota Statutes. This plan is an update to the 2006 LSWMP. The plan will guide stormwater activities in the City for the next 10 years (2018-2027). Periodic amendment to the SWMP will likely occur in the intervening 10 years so that the SWMP remains current to watershed plan amendments and Metropolitan Council requirements. The City of Mendota Heights (population 11,172) is located in northern Dakota County at the confluence of the Mississippi and Minnesota Rivers (Figure 1). Mendota Heights is a well-established community that is fully developed. The City has put emphasis on high quality residential neighborhoods, open space and parks, and well-planned commercial and industrial areas. SECTION 1 Surface Water Management Plan Section 1 City of Mendota Heights WSB Project No. 1735-04 Page-3 The Township of Mendota was organized in 1858. After World War II, the area experiencing rapid growth and the need for community planning and services prompted a portion of the original township to incorporate as the Village of Mendota Heights in 1956. The Village of Mendota Heights became the City of Mendota Heights in 1974. Mendota Heights is a first-ring suburb located between the City of West St. Paul and Sunfish Lake to the east, Minneapolis – St. Paul International Airport and Fort Snelling to the West, City of Eagan to the south, and City of St. Paul to the north. Mendota Heights falls within two watershed districts: Lower Mississippi Watershed Management Organization and the Lower Minnesota River Watershed District. This plan addresses the rules and regulations put forth by the both. The City of Mendota Heights is considered fully developed. Section 2.3 of this plan discusses land use in the City. 1.4.2. Summary of Implementation Section Section 6 of this plan presents the implementation program for the City of Mendota Heights, which includes defining responsibilities, prioritizing, and listing the program elements. Table 6.1, outlines the projects, programs, studies, and Storm Water Pollution Prevention Plan (SWPPP) activities that have been identified as a priority to address water resource needs and problem areas within the City. SECTION 2 Surface Water Management Plan Section 2 City of Mendota Heights WSB Project No. 1735-04 Page-1 2. LAND AND WATER RESOURCE INVENTORY 2.1. Land Use Figure 1 provides the land use classifications for the City of Mendota Heights, and comes directly from the City’s 2030 Comprehensive Plan (Comprehensive Plan). The Comprehensive Plan states that the City of Mendota Heights is predominantly developed. However, the City has maintained substantial areas of public open space, wetlands, lakes, bluffs and wooded areas that give the impression of a lower density of development. According to the Comprehensive Plan, the City will strive to maintain and enrich the mature, fully developed residential environment by preserving natural features and the environment while promoting high quality and well-functioning developments. The Comprehensive Plan provides a significant amount of narrative and statistical detail on existing and proposed land use and the reader is referred to that document for more information on land use planning. There are a few areas of note that relate to surface water management, one of which is the concentrated industrial area between Highway 13, Highway 55, and Interstate 494. Having a concentrated area of impervious area can be opportunity for regional stormwater treatment when new development occurs, but it can also be a potential hotspot for stormwater pollution and management issues. The Comprehensive Plan references “focus” areas, or areas remaining to be developed. The focus areas in the Comprehensive Plan are Pilot Knob and Acacia Site, Somerset Area, St. Thomas/Visitation Campuses, Dodd/Highway 110, Furlong District, and “Infill” Sites (any property that has the opportunity to develop, or redevelop, beyond its current level). These focus areas have the potential to play an important role in the management of surface water during the next ten years. As the sites develop and potentially impact water quality and public safety, it will be essential that guidelines and best management practices, as outlined in this SWMP, are followed by developers. The hydrologic modeling that supports the SWMP used the land use that was used in the 2006 Local Surface Water Management Plan hydrologic model. A combination of aerial photos, the land use classification map, and as-built drawings were used to determine hydrologic characteristics of the full development landscape. Changes from undeveloped land uses—such as natural and agricultural—to more heavily developed land uses —such as low, medium and high density residential and commercial—have a pronounced effect on hydrology. The increased impervious surface associated with the urban land uses leads to higher runoff peak flows and increased runoff volumes. The City is unique in that although it is mostly developed, the land use consists of large areas of institutional land, resulting in less impervious area and more green and open space. 2.2. Topography and Watersheds The surficial geology of Mendota Heights consists of the glacial and alluvial (outwash) deposits which cover most of the City. Most of Mendota Heights is rolling to hilly terrain interspersed with poorly drained depressions that form many ponds and small lakes. The Comprehensive Plan provides additional detail on the general topography of the City. The City of Mendota Heights is located near the confluence of the Minnesota and Mississippi Rivers in northern Dakota County. Steep slopes occur along the Minnesota and Mississippi river bluffs along the west and north border of the City. Elevation in the City ranges from approximately 690 feet along the Minnesota River to approximately 1,030 feet along the City’s border with West St. Paul. The steep slopes along the river bluffs often result in challenges during hydrologic design and planning to prevent erosion. Additionally, at the bottom of the Minnesota River Bluff adjacent to SECTION 2 Surface Water Management Plan Section 2 City of Mendota Heights WSB Project No. 1735-04 Page-2 Highway 13 is the Gun Club Lake Fen, a calcareous fen with rare and important indicator vegetation for the ecosystem. There has been significant work by LMRWD to improve and protect this resource, which includes special considerations when managing stormwater discharge into the area. The City’s hydrologic system is part of both the Mississippi River and Minnesota River watersheds. The City resides within one watershed management organization and one watershed district. The southwestern portion of the City resides in the LMRWD. The remaining portion of the City lies within the LMRWMO. Figure 2 shows jurisdictional boundaries for the two watershed organizations within the City. The City of Mendota Heights has contour data that cover the entire City and is based on 2011 LIDAR (Light Detection and Ranging) data. Information regarding the City’s surficial and bedrock geology and aquifers is available in the Dakota County Geologic Atlas from the Minnesota Geological Survey. 2.3. Soils Soils of the Mendota Heights area are classified into three associations of multiple soil series: x Kingsley-Mahtomedi Association x Waukegan-Wadena Hawick Association x Colo-Algansee-Minneiska Association Information about each of the soils in these associations area available from the Soil Survey of Dakota County (SCS 1983). Table 2.1 shows the drainage characteristics of each soil series from the above associations. The drainage nature of the soil is important for determining surface water runoff from a given area. If the soil is well-drained, a significant portion of the precipitation will be infiltrated into the ground, whereas if a soil is very poorly drained much more precipitation becomes runoff. The Hydrologic Soil Group (HSG) defines a soil’s propensity to generate runoff for a given runoff event.

Existing Flood Insurance Studies A search of the Federal Emergency Management Agency (FEMA) website showed no flood insurance studies for the City of Mendota Heights, other than those for the Mississippi and Minnesota Rivers. The Flood Insurance Rate Map for Mendota Heights is effective as of December 2, 2011. Mendota Heights is community number 270110. 2.5. Key Water Resources Surface waters throughout the City are available for the use and enjoyment of its residents. Many of surface waters that provide an aesthetic amenity to the community also double as a means of access for stormwater to wind its way towards its outfall. These major water resources tend to be State of Minnesota public waters. Below is a brief summary of the major surface water resources. The public waters are labeled with their Public Waters Inventory (PWI) number. Augusta Lake (PWI #19-81P) Lake Augusta is a Minnesota Department of Natural Resources (DNR) public water. It is a deep lake with a maximum depth of 33 feet, and an area of 44 acres. The area of its watershed is 410 acres. LeMay Lake (PWI #19-82W) This lake is considered a public water wetland by the Minnesota DNR. It is a shallow lake and drains to an outlet under Highway 55. LeMay Lake is next to a residential neighborhood. Gun Club Lake (PWI #19-78P) Gun Club Lake and the stream it discharges to are both public waters. The lake is located along the Minnesota River within its floodplain. This lake discharges to an unnamed stream that flows to the Minnesota River, and although it is located in the City, it is managed by Fort Snelling State Park. Rogers Lake (PWI #19-80P) A shallow lake with a maximum depth of eight feet, Rogers Lake covers a surface area of approximately 114 acres. It discharges to a storm sewer pipe along Wagon Wheel Trail. Interstate Valley Creek This creek is an intermittent stream that begins near the intersection of Highway 110 and Highway 149 (Dodd Road) at the outflow point of Friendly Marsh. The creek flows northward, generally parallels Interstate 35E. Interstate Valley Creek is the single largest watershed within the City of Mendota Heights, and includes areas within the cities of Inver Grove Heights, Sunfish Lake, and West St. Paul. Ivy Falls Creek Ivy Falls Creek is an intermittent stream that begins at the Somerset Golf Course. The gradient of the stream is steep, it drops down 180 feet in the 3,000 feet from Dodd Road to Highway 13, including a 50-foot drop at Ivy Falls. The steep gradient has allowed erosion problems to occur. The creek eventually discharges to Pickerel Lake in the City of Lilydale. Minnesota and Mississippi Rivers Both of these rivers are Minnesota public waters. Shorelines of both of these rivers are found within city limits, but these shorelines are also in Fort Snelling State Park. The Minnesota and Mississippi River shorelines that are within the City’s limits are managed by Fort Snelling State Park and the St. Paul Parks and Recreation Department. SECTION 2 Surface Water Management Plan Section 2 City of Mendota Heights WSB Project No. 1735-04 Page-4 Impaired Waters The MPCA lists the following water bodies located within or near the City as being impaired, meaning that the waters are too polluted or otherwise degraded to meet the water quality standards set by governing bodies: Table 2.3 Summary of Impaired Water Bodies Impaired Water Body Impairment Minnesota River (ID 07020012-505) x Turbidity (1996) x Dissolved Oxygen (1998) x Mercury in water column and fish tissue (1998) x Polychlorinated biphenyls (PCB) in fish tissue (1998) Mississippi River (ID 07010206-509) x Fecal Coliform (1998) x PCB in fish tissue (2006) Augusta Lake (ID 19-0081-00) x Nutrient/eutrophication biological indicators (2010) Unnamed Creek (ID 07010206-542) x E.Coli The locations of these impaired water bodies are shown on the water resource problem areas map (Figure 3, Appendix A). For more information on impaired waters and TMDL Plans visit the MPCA website http://www.pca.state.mn.us/. The MPCA website contains an Impaired Waters Viewer, an interactive map that can be used to view impaired waters and their updated water quality data, as well as their updated TMDL Plans. In addition to the water bodies listed above, the City is upstream of other reaches of the Mississippi River. The City may be required to implement the TMDL plans for these water bodies once complete. 2.6. Natural Communities and Rare Species A Minnesota Land Cover Classification System (MLCCS) search was performed for the areas below the bluffs, where land cover is divided into levels of importance and type. The bluffs themselves are upland areas. Table 2.2 shows a listing of the land cover types below the bluffs and the area of each type that falls within the Mendota Heights City limits. Of special note is the presence of calcareous seepage fen prairie. The LMRWD and the MLCCS consider calcareous fens to be high priority areas for wetland preservation and restoration. Table 2.2 MLSS Summary of Areas Below the Bluffs City of Mendota Heights Land Cover Description Total Area (acres) Oak (forest or woodland) with 11-25% impervious cover 1.9 51% to 75% impervious cover with deciduous trees 18.0 Pavement with 91-100% impervious cover 2.5 Short grasses with sparse tree cover on upland soils 10.2 Short grasses on upland soils 5.5 Oak forest 3.9 Floodplain forest 209.8 Lowland hardwood forest 6.1 Aspen forest - temporarily flooded 1.5 Mixed hardwood swamp - seasonally flooded 7.2 SECTION 2 Surface Water Management Plan Section 2 City of Mendota Heights WSB Project No. 1735-04 Page-5 Altered/non-native deciduous woodland 2.8 Altered/non-native dominated temporarily flooded shrubland 0.8 Willow swamp 3.3 Medium-tall grass altered/non-native dominated grassland 12.8 Temporarily flooded altered/non-native dominated grassland 2.0 Calcareous seepage fen prairie subtype 37.0 Mixed emergent marsh - seasonally flooded 62.5 Mixed emergent marsh 106.4 Mixed emergent marsh - intermittently exposed 57.2 Mixed emergent marsh - permanently flooded 22.1 Grassland with sparse deciduous trees - altered/non-native dominated vegetation 3.4 River mud flats 3.6 Slow moving linear open water habitat 139.3 Limnetic open water 145.1 Palustrine open water 41.6 Water Quality Data Water quality data for the City can be obtained from the MPCA’s Environmental Data Access site and up to date information is located on their website. This data provides a snapshot of overall water quality and health of local waterbodies. This database is utilized by participating agencies to compile water quality testing data and is almost entirely used for the storage of water quality parameters. This water quality monitoring information/data and monitoring locations can be found at the MPCA’s Environmental Data Access site at https://www.pca.state.mn.us/water/water-monitoring-and-reporting. The LMRWD and LMRWMO also monitor creeks and lakes within Mendota Heights. Citizens can visit the respective websites for the most recent monitoring report. 2.7. Groundwater and Water Supply Various agencies are responsible for groundwater management and protection. The DNR regulates groundwater usage rate and volume as part of its charge to conserve and use the waters of the state. Suppliers of domestic water to more than 25 people or applicants proposing a use that exceeds 10,000 gallons per day or 1,000,000 gallons per year must obtain a water appropriation permit from the DNR. Many of the agencies charged with regulating water usage are currently involved in assessing and addressing concerns of water usage. When and where feasible, the City of Mendota Heights will work with the associated agencies to be good stewards of water resources. The Minnesota Department of Health (MDH) is the official state agency responsible for addressing all environmental health matters, including groundwater protection. For example, the MDH administers the well abandonment program, and along with the Minnesota DNR, regulates installation of new wells. The MPCA administers and enforces laws relating to pollution of the state's waters, including groundwater. The Minnesota Geological Survey provides a complete account of the state's groundwater resources. Dakota County has statutory responsibilities for groundwater management contained in its Environment and Natural Resource Management Policy Plan (adopted and approved in 2006). Dakota County is currently revising the county comprehensive plan, which is scheduled to be submitted for the Board of Water and Soil Resources (BWSR) approval in 2018. At this time the City of Mendota Heights is not aware of any Drinking Water Supply Management Areas (DWSMAs) within the City’s boundaries. However, parts of the City have been fl agged as significantly vulnerable to groundwater contamination. Refer to the Dakota County Comprehensive Plan for the most up to date information on DWSMAs and groundwater status. SECTION 2 Surface Water Management Plan Section 2 City of Mendota Heights WSB Project No. 1735-04 Page-6 2.8. Hydrologic System and Data The City has been divided into four major watershed areas: Gun Club Lake, Ivy Falls Creek, Mississippi Bluffs, and Interstate Valley Creek. Each of these four watershed areas have HydroCAD models that were updated from the 2006 LSWMP for the 2018 SWMP to include the new NOAA Atlas 14 Precipitation Frequency Estimates. The updated HydroCAD Models were used to develop a P8 Urban Catchment Model. Modeling results and discussion can be found in Appendix E, and narrative on the City’s Hydrologic System can be found in Section 4.3. 2.9. NPDES MS4 Permit The City is holder of an NPDES MS4 Permit, which includes a SWPPP. The City completed a reauthorization in 2013, that included an evaluation of the City’s stormwater system, resulting in a final SWPPP that includes existing and proposed BMPs, responsible persons, measurable goals, and timelines for implementation. 2.10. Water Resource Management Ordinances and Policies The City Ordinance for Mendota Heights includes Stormwater Management, Illicit Discharge, . The City Ordinance can be found online at the City of Mendota Heights website, and includes sections on construction site management stormwater, illicit discharge and storm sewer connection regulations, and post-construction stormwater runoff regulations. SECTION 3 Stormwater Management Plan Section 3 City of Mendota Heights WSB Project No. 1735-04 Page-1 3. AGENCY COOPERATION There are several local, state, and federal agencies that have rules and regulations related to local water management. The City recognizes the roles of these other agencies and will cooperate, coordinate, and partner when possible with these agencies. This SWMP is in conformance with, but does not restate, all other agency rules that are applicable to water resource management. The following agencies deal with or regulate water resources throughout the City: Minnesota Department of Health (www.health.state.mn.us) Minnesota Pollution Control Agency( www.pca.state.mn.us) Board of Water and Soil Resources (www.bwsr.state.mn.us) and the Wetland Conservation Act (www.bwsr.state.mn.us/wetlands/wca/index.html) Minnesota Department of Natural Resources (www.dnr.state.mn.us) US Army Corps of Engineers (www.mvp.usace.army.mi) Minnesota Department of Agriculture (www.mda.state.mn.us) US Fish and Wildlife Service (www.fws.gov) Dakota County Soil and Water Conservation District (http://www.dakotaswcd.org/) Lower Mississippi River Watershed Management Organization (http://www.dakotaswcd.org/watersheds/lowermisswmo/) Lower Minnesota River Watershed District (http://www.watersheddistrict.org/) Minnesota Environmental Quality Board (www.eqb.state.mn.us) Metropolitan Council (www.metrocouncil.org) While these other agencies’ rules, policies, and guidelines are not all restated in this SWMP, they are applicable to projects, programs, and planning within the City. The MPCA Minnesota Stormwater Manual, which is a document intended to be frequently updated, is also incorporated by reference into this SWMP and can be found at www.pca.state.mn.us/water/stormwater/stormwater-manual.html. 3.1. County, State, and Federal Agency Requirements This section of the SWMP presents a synopsis of the current agency requirements while acknowledging the existence of other requirements that may be applicable. The City is committed to the preservation and enhancement of its wetlands and water resources through full compliance with local, state, and federal wetland regulations. 3.1.1. Minnesota Department of Natural Resources Types 3, 4, and 5 wetlands are protected by statute at the state level. These are areas typically recognized as wetlands and are generally characterized by open water and emergent vegetation throughout most of the year. The state has jurisdiction over only those wetlands appearing on the State’s inventory of protected waters. Further, wetlands in the inventory are generally those in excess of ten acres in rural areas or in excess of two and a half acres in municipalities and incorporated areas. Figure 6 shows the DNR protected waters within the Mendota Heights SWMP study area. If an area meets the jurisdictional criteria but is not on the State’s inventory, it is not regulated by the DNR. If it does not meet the statutory criteria but is listed on the inventory, it still is subject to DNR regulation. There is currently no mechanism for adding wetlands to or deleting wetlands from the inventory. The inventory was begun in the late 1970s and all state inventories were completed during the early 1980s. The DNR rules specify that permits may not be issued for any project except those that provide for public health, safety, and welfare. Any private development projects are effectively excluded from permit consideration by this requirement. SECTION 3 Stormwater Management Plan Section 3 City of Mendota Heights WSB Project No. 1735-04 Page-2 The western portions of the City abutting the Minnesota River are located in the Mississippi River Critical Area Corridor. According to the DNR: The purposes of designating the Mississippi River and this portion of the Minnesota River as a state critical area include the following: a) protecting and preserving a unique and valuable state and regional resource for the benefit of the health, safety, and welfare of the citizens for the state, region, and nation; b) preventing and mitigating irreversible damage to this resource; c) preserving and enhancing its natural, aesthetic, cultural, and historical value for public use; d) protecting and preserving the river as an essential element in the national, state, and regional transportation, sewer and water, and recreational systems; and protecting and preserving the biological and ecological functions of the corridor. The DNR has three primary roles for the Mississippi River Critical Area Program. The DNR has undertaken the mandate of reviewing existing ordinances that affect lands within the Mississippi River Critical Area Corridor for their compliance with state critical area standards and guidelines. Technical assistance for ordinance development will be provided to local communities to ensure adoption and approval of a compliant state critical area ordinance or any ordinance amendments. DNR will also provide individualized technical assistance for amending existing ordinances or developing proposed ordinances that will be consistent with the voluntary Mississippi National River and Recreation Area (MNRRA) Comprehensive Management Plan policies. In addition, adoption or amendment of plans and ordinances affecting lands within the Mississippi River Critical Area Corridor and relating to Executive Order 79-19 purposes and standards are effective only after approval by the DNR. The DNR reviews the plans and ordinances to ensure their consistency with the provisions of Executive Order 79-19, following an evaluation by the Metropolitan Council. In communities where critical area plans and ordinances have become effective, the local governmental unit also must notify the DNR area hydrologist at least 30 days before action is taken for all development applications or variances requiring a public hearing or discretionary action. In communities where plans and regulations have not been adopted or approved, the DNR is also to be notified about additional types of projects listed in the Interim Regulations. DNR will review and comment on the project's compliance with critical area and state requirements and MNRRA policies, as well as provide technical assistance as requested. Notice of the final action is to be sent to the DNR. The City of Mendota Heights has adopted appropriate rules and ordinance to serve as the local government unit (LGU) conducting critical area review and implementation. As the Minnesota DNR adopts new rules the City will in turn revise its rules and ordinance to remain the LGU. In cases where a large subdivision of land might occur within the Critical Area, the City would transfer its review authority to the Minnesota DNR. The other powers and duties of this Minnesota state agency and its commissioner are wide- ranging. As they affect surface water management within the City they include: Regulation of all public waters inventory waterbodies within the City – to the extent of SECTION 3 Stormwater Management Plan Section 3 City of Mendota Heights WSB Project No. 1735-04 Page-3 their ordinary high water level (OHWL). Regulation of certified floodplains around rivers, creeks, lakes and wetlands. Management of the Flood Hazard Mitigation program. Shoreland Management. 3.1.2. US Army Corps of Engineer (USACE) The Environmental Protection Agency (EPA) and the USACE regulate the placement of fill into all wetlands of the U.S. In 1993, the definition of "discharge of dredged material” was modified to include incidental discharges associated with excavation. This modification of the “discharge of dredged material” definition meant that any excavation done within a wetland required the applicant to go through Section 404 permitting procedures. In 1998, however, this decision was modified so that excavation in wetlands is now regulated by the USACE only when it is associated with a fill action. 3.1.3. Board of Water and Soil Resources (BWSR) The local and regional wetland rules are governed by the WCA. The WCA, passed in 1991, extends protection to all wetlands unless they fall under one of the exemptions. The WCA follows a “no net loss” policy. The wetlands covered under the WCA must not be drained or filled, wholly or partially, unless replaced by restoring or creating wetland of at least equal public value under an approved replacement plan. Replacement ratio is typically two acres created for every one acre filled for wetland impacts. A designated LGU is responsible for making exemption and no-loss determinations as well as approving replacement plans. Currently, Mendota Heights acts as the LGU for the WCA within the City’s subdivision authority. The powers and duties of BWSR include: Coordination of water and soil resources planning among counties, watersheds, and local units of government. Facilitation of communication among state agencies in cooperation with the Environmental Quality Board. Approval of watershed management plans. 3.1.4. Minnesota Pollution Control Agency (MPCA) The MPCA implements provisions of Section 404 of the Clean Water Act with guidance from the EPA through a permitting process. The Section 404 permit also requires a Section 401 water quality certification before it is valid. The EPA has given Section 401 certification authority to the MPCA. The powers and duties MPCA and its commissioner include: Fulfilling mandates from the EPA, particularly in regard to the Clean Water Act. Administration of Mendota Heights’ NPDES Phase II MS4 permit. Administration of the NPDES construction site permit program. Administration of the NPDES industrial site discharge permit program. Development of TMDLs for waterbodies and watercourses in Minnesota (often in conjunction with other agencies or joint powers organizations such as watersheds). 3.1.5. Environmental Protection Agency (EPA) SECTION 3 Stormwater Management Plan Section 3 City of Mendota Heights WSB Project No. 1735-04 Page-4 As it relates to surface water management within Mendota Heights, the EPA is charged with interpreting and applying aspects of the Clean Water Act. This has led to the City’s need for its NPDES MS4 permit. Total maximum daily load limits, a new initiative mandated by the EPA, also stem from the EPA’s role as steward of the Clean Water Act. 3.1.6. Lower Minnesota River Watershed District (LMRWD) and Lower Mississippi River Watershed Management Organization (LMRWMO) The powers and duties of these Minnesota statutory authorities include: Approval authority over local water management plans. Ability to develop rules regarding management of the surface water system. Ability to determine a budget and raise revenue for the purpose of covering administrative and capital improvement costs. Regulation of land use and development when one or more of the following apply: o The City does not have an approved local plan in place. o The City is in violation of their approved local plan. o The City authorizes the watershed toward such regulation. Other powers and duties as given in statute and joint powers agreements. 3.1.7. State and Federal Jurisdictional Boundaries for Public Wetlands and Waters Wetlands are delineated in accordance with the Federal Manual for Identifying and Delineating Jurisdictional Wetlands (1987). Wetlands must have a predominance of hydric soils. Hydric soils by definition are inundated or saturated by surface water or groundwater at a frequency and duration sufficient to support, under normal circumstances, a prevalence of hydrophytic (water tolerant) vegetation typically adapted for life in saturated soil conditions. The USACE and the BWSR regulate wetlands as defined by a jurisdictional delineation. For wetlands that fall under the Minnesota DNR jurisdiction, the OHWL determines the boundary of the Minnesota DNR’s jurisdiction. The OHWL is established by the DNR. 3.1.8. Dakota County Dakota County Soil and Water Conservation District (SWCD) sits on the Technical Evaluation Panel for administration of the WCA. 3.1.9. Metropolitan Council Metropolitan Council, through Metropolitan Council Environmental Services, serves as a review agency for local surface water management plans. They also review and approve municipal comprehensive plans and have a prominent role in the Mississippi River Critical Area Corridor as described on the DNR website: “The Metropolitan Council reviews existing plans that affect lands within the Mississippi River Critical Area Corridor. Technical assistance is provided to assist communities in amending or adopting plans to become consistent with Executive Order 79-19 standards and guidelines and any voluntary MNRRA Comprehensive Management Plan policies. The council reviews all critical area plans and ordinances and makes an evaluation to DNR prior to the approval decision. In addition, the council administers the pass-through funds from the National Park Service to provide financial assistance to communities wishing to revise their plans and ordinances. The council is also involved with oversight of the Metropolitan Land Planning Act.” SECTION 4 Stormwater Management Plan Section 4 City of Mendota Heights WSB Project No. 1735-04 Page-1 4. ASSESSMENT OF ISSUES Section 4 is an assessment of existing and potential local water resource-related issues that are known as of 2018. These issues have been identified based on an analysis of the land and water resource data collected during the preparation of this SWMP and through information provided by the City, its residents, and the watershed organizations. A description of any existing or potential issue within the City has been listed and potential future corrective actions have been incorporated into an implementation plan in Section 6. Refer to Figure 5 for the location of many of the issues discussed below. 4.1. Water Quality Assessments 4.1.1. City Assessment The City investigated the location of stormwater discharge into a fen that is located near the southwest part of the City. The assumption was that the stormwater was discharging to the Fort Snelling State Park Fen, which is a Restricted Discharge Water under the City’s National Pollutant Discharge Elimination System (NPDES) permit. But the investigation determined that the stormwater discharge flowed to the Gun Club Lake Fen, which is not a Restricted Discharge Water. The City prepared a self-assessment as part of developing its SWPPP. In that self- assessment, a list of potential sources or types of pollution was developed. The City does not know of a particular source or type of pollution that is prevalent within the City. Although it is not a list of actual pollution occurrences, the list repeated below does provide information for consideration and management.. At Ivy Park Pond, there appears to be a problem where skimmers are collecting excessive floatables. A significant portion of stormwater entering the pond comes from West St. Paul. Increased maintenance attention is paid to this location. Lawn and landscape fertilizers are a potential source of pollution. The City purchases and uses only phosphorous-free products. The application of fertilizers containing phosphorus is currently prohibited by state law unless the results of a soil test show that phosphorus is indeed the limiting nutrient for turf growth. A typical salt is used on the streets. The City recognizes chloride pollution as a water quality issue, and is looking at alternative deicing products to reduce salt and sediment in stormwater and reduce street sweeping costs. Additionally, the City is looking to incorporate the Twin Cities Metropolitan Area Chloride Management Plan to reduce salt use during winter applications. Emergency fuel dumping from aircraft flying into the Minneapolis-St. Paul International airport is a potential source of pollution. In the past, citizens have reported strong jet fuel odors believed to be from fuel dumping. Fuel dumping is not known to be a frequent problem. Pet waste is recognized as a nuisance and a pollution source. Signs in parks instruct pet owners to clean up after their pets, as required by ordinance. Waste from geese is considered a serious problem. Geese use the City’s lakes and ponds throughout the year. Failing septic systems are a potential source of pollution, although not currently perceived to be a problem. Approximately 40 septic systems exist in the City. City ordinance requires inspections of the systems. The Mendota Heights ordinance that regulates septic systems is identical to that of Dakota County and meets all Metropolitan Council and MPCA requirements. Soil erosion along the bluffs and at construction sites is a potential source of pollution. The storm sewer system contains some hanging outfalls, and there is scour around some outfalls. SECTION 4 Stormwater Management Plan Section 4 City of Mendota Heights WSB Project No. 1735-04 Page-2 4.1.2. Clean Water Act Assessments The Impaired Waters List, also known as the 303(d) list from the applicable section of the federal Clean Water Act, records waters that do not currently meet their designated use due to the impact of a particular pollutant or stressor. If monitoring and assessment indicate that a water body is impaired by one or more pollutants, it is placed on the list. At some point after being added to the list, a strategy would be developed that would lead to attainment of the applicable water quality standard. The process of developing this strategy is commonly known as the TMDL process and involves the following phases: 1. Assessment and listing 2. TMDL study 3. Implementation plan development and implementation 4. Monitoring of the effectiveness of implementation efforts Responsibility for implementing the requirements of the federal Clean Water Act falls to the US Environmental Protection Agency (USEPA). In Minnesota, the USEPA delegates much of the program responsibility to the MPCA. Information on the MPCA program can be obtained at the following web address: https://www.pca.state.mn.us/water/total-maximum-daily-load-tmdl-projects A map of impaired waters in Mendota Heights and TMDL’s can be found at the following web address: https://www.pca.state.mn.us/water/impaired-waters-viewer-iwav Table 4.1 Lists the 303(d) impaired waters within the City of Mendota Heights Table 4.1 303(d) 2016 Final List of Impaired Waters Within the City of Mendota Heights Water Body Year First Listed Assessment Unit ID # Affected Use Pollutant or Stressor TMDL start/TMDL complete Minnesota River 1998 07020012-505 Aquatic life Dissolved oxygen 2004*/- Minnesota River 1998 07020012-505 Aquatic consumption Mercury in water column 2008*/- Minnesota River 1998 07020012-505 Aquatic consumption Mercury in fish tissue 2008*/- Minnesota River 1998 07020012-505 Aquatic consumption PCB in fish tissue 1998/2025 Minnesota River 1996 07020012-505 Aquatic life Turbidity 2014/2019 Augusta Lake 2010 07010206-506 Aquatic Recreation Nutrient/Eutrophicatio n Biological Indicators 2010/2014 *TMDL Plan has been approved but has not been started. SECTION 4 Stormwater Management Plan Section 4 City of Mendota Heights WSB Project No. 1735-04 Page-3 Upstream from the Mendota Heights city limits, the Mississippi River is also listed as impaired (assessment unit ID 07010206-509). This listing could potentially affect management of drainage that directly discharges to the river. The river’s affected uses are aquatic consumption and aquatic recreation. The pollutants or stressors that have been identified as causing these impairments are: Mercury in fish tissue PCB in fish tissue Fecal Coliform The absence of a waterbody from the 303(d) list does not necessarily mean the waterbody is meeting its designated uses. It may be that it has either not been sampled or there is not enough data to make an impairment determination. Additionally, where mercury is identified as a stressor, the TMDL approach will be regional in nature as mercury is most commonly an air-borne pollutant. City of Mendota Heights Actions: It remains to be seen how the TMDL issues will be resolved for the Minnesota River and the Mississippi River. Each river’s basin encompasses a significant portion of the state of Minnesota. It remains to be seen whether the TMDLs for the rivers will be implemented basin-wide or along specific reaches 4.1.3. Lower Mississippi River Watershed Management Organization (LMRWMO) The LMRWMO has assessed the water quality of select lakes and ponds within its jurisdiction. It was noted in the LMRWMO Watershed Management Plan (WMP) that, generally, additional water quality data needs to be collected. The LMRWMO WMP noted that water quality assessments should be performed on Roger’s Lake in Mendota Heights. According to the WMP, this lake formerly supported a public swimming beach and is popular among local residents for panfish fishing. Water quality monitoring data should be collected to classify the lake and watch trends. Interstate Valley Creek and Augusta Lake are also noted as a resource of concern for water quality problems. In 2014, LMRWMO completed a Watershed Restoration and Protection Strategy (WRAPS) Report that includes water quality data for Lake Augusta and Rogers Lake, a TMDL for Lake Augusta. The WRAPS Report can be found at LMRWMO’s website. 4.1.4. Lower Minnesota River Watershed District (LMRWD) Within the LMRWD’s WMP, there is an emphasis on assessing water quality within the Minnesota River. Water quality assessment data is available for the Minnesota River and many of its tributary streams within the WMP. 4.2. Water Quantity Assessments 4.2.1. City Assessments Since the City prepared its 2006 Water Resources Management Plan (WRMP), no new water quantity assessments have been conducted. This does not mean that the City has not been addressing new water quantity issues, only that these have not been significant enough in scope to warrant mention in this SWMP. 4.2.2. Lower Mississippi River Watershed Management Organization (LMRWMO) SECTION 4 Stormwater Management Plan Section 4 City of Mendota Heights WSB Project No. 1735-04 Page-4 In its WMP, the LMRWMO assessed intercommunity surface water management issues that the watershed should resolve. In addition, the LMRWMO Plan requires that member cities prioritize shoreland areas for restoration. Item 4 in Table 6.1 shows that the City plans to allocate funds to address issues of shoreland erosion along Interstate Valley Creek, the priority area, for bank stabilization projects. Table 4.2 summarizes these issues, which are related to flooding and erosion. Table 4.2 Erosion and Flooding Issues Related to the City of Mendota Heights 4.2.3. Lower Minnesota River Watershed District (LMRWD) Figure 5 shows the Mendota Heights drainage system in some detail. One of the primary discharges from this system occurs through a 54-inch pipe into the Minnesota Department of Transportation (MnDOT) system adjacent to and under Trunk Highway 13. The highway system carries MnDOT and Mendota Heights runoff water into the Quarry Island fen, as indicated by the flow arrows on Figure 5. The Quarry Island fen lies within the jurisdiction of the LMRWD and the district is considering whether to pursue a detailed assessment and monitoring program for this fen. Regardless of what the watershed does toward studying the area, it is highly likely that the LMRWD and DNR will pursue a project to reroute this drainage around the fen and into Gun Club Lake. The City and MnDOT are likely to be financial participants in this project when it becomes a reality. The City’s share of the project cost could be substantial. Given this, the implementation section of this SWMP includes an item for the Quarry Island fen storm drainage project with an unknown date for implementation 4.3. System Description This subsection describes the surface water management system for the City of Mendota Heights. The SWMP area was organized into four major topographic watersheds: Interstate Valley Creek Watershed Ivy Falls Creek Watershed Mississippi River Bluffs Watershed Gun Club Lake Watershed The Interstate Valley, Ivy Falls Creek, Mississippi River Bluff, and Gun Club Lake topographic watersheds generally lie within the LMRWMO jurisdiction. Each major watershed was divided into drainage districts. The drainage districts are generally drawn to encompass all drainage to a particular pond, wetland, or lake. The City’s 1993 Plan identified 14 major drainage districts. To simplify the modeling nomenclature and allow easier cross referencing between the model and Figure 5, drainage districts within this SWMP carry the Name Location Issue Status Interstate Valley Creek Watershed Interstate Valley Creek north of Marie Avenue. Watershed includes Inver Grove Heights, Sunfish Lake, Mendota Heights, and West St. Paul Erosion Ongoing issue which has been addressed in some select locations. Additional stream bank stabilization projects will likely be needed.

Figure 5 in Appendix A includes areas for the subwatersheds within each major watershed. Appendix E includes the pond data. 4.3.1. Interstate Valley Creek Watershed (IV) The Interstate Valley Creek Watershed consists of all areas that drain to the point where Trunk Highway (TH) 13 crosses Interstate Valley Creek. The watershed’s total area is approximately 4,224 acres, of which 3,004 acres are in Mendota Heights, 414 acres are in West St. Paul, 676 acres are in the City of Sunfish Lake (including the 234-acre Sunfish Lake Watershed, which is landlocked), and 130 acres are in Inver Grove Heights. Interstate Valley Creek is an intermittent stream that begins near the intersection of TH 110 and TH 149 (Dodd Road) at the outflow point of a large wetland (Friendly Marsh). The creek flows northward under TH 110 through a 72-inch reinforced concrete pipe (RCP) culvert. From TH 110 the creek flows 1.9 miles through Valley Park before discharging to the Mississippi River. The creek flows through culverts at Marie Avenue, at a bicycle path crossing downstream of Marie Avenue, and at Lilydale Road. Because of its relatively large size, the portion of the Interstate Valley Creek Watershed within Mendota Heights is divided into six drainage districts. Rogers Lake Drainage Subwatershed The Rogers Lake Drainage Subwatershed is nearly fully developed. This district consists of Rogers Lake and the area that drains to the lake. Rogers Lake is the district’s major hydrologic feature. The lake consists of two basins which are divided by Wagon Wheel Trail. A 73-inch span arch pipe culvert connects the two basins. The outlet of Rogers Lake is via a 30-inch RCP that connects to a storm sewer system that discharges to the Friendly Marsh District, as shown on Figure 5. SECTION 4 Stormwater Management Plan Section 4 City of Mendota Heights WSB Project No. 1735-04 Page-6 West of I-35E, the land use is predominantly single-family residential, while east of I-35E a large part of the upland in this area consists of the Mendakota Country Club golf course. Single-family homes and schools exist in the district south and east of Rogers Lake. A small area south of the lake and adjacent to I-35E is undeveloped but planned as office/industrial land use. Southeast Drainage Subwatershed The Southeast Drainage Subwatershed mostly consists of single-family homes. Within Sunfish Lake and Inver Grove Heights, 693 acres are tributary to the Southeast Drainage Subwatershed though 234 acres of this tributary area is actually landlocked by Sunfish Lake. This drainage flows from the City of Sunfish Lake into the Southeast Drainage Subwatershed through two separate culverts under County Road 63 (Delaware Avenue). Drainage from this district flows to the Friendly Marsh Drainage Subwatershed. Friendly Marsh Drainage Subwatershed The Friendly Marsh Drainage Subwatershed is generally located south of TH 110 and west of Delaware Avenue. Open space is a significant land use in this district due to the presence of the Dodge Nature Center. Single-family residential is the other predominant land use. This district receives drainage from approximately 301 acres in the cities of Sunfish Lake and West St. Paul via two culverts under Delaware Avenue. Water from the Rogers Lake and the Southeast Drainage Subwatershed also discharges into the Friendly Marsh Drainage Subwatershed. The subwatershed discharges to the Lower Interstate Valley Drainage Subwatershed. Friendly Marsh is a ditched wetland that serves as the headwaters to Interstate Valley Creek. West Marie Avenue Drainage Subwatershed This watershed is located along Marie Avenue, generally west of I-35E. The predominant land use is single- and multiple-family residential. This watershed discharges to the Lower Interstate Valley Drainage Subwatershed. East Marie Avenue Drainage Subwatershed The East Marie Avenue Drainage Subwatershed is located along Marie Avenue east of Interstate Valley Creek. Marie Creek flows through this district. The predominant land use is single-family residential. Drainage from approximately 169 acres in West St. Paul is tributary to this drainage subwatershed. The stormwater runoff from the East Marie Avenue Drainage Subwatershed discharges to the Lower Interstate Valley Drainage Subwatershed. Lower Interstate Valley Drainage Subwatershed Significant open areas exist along Interstate Valley Creek and at two golf courses located in this subwatershed. Drainage from 57 acres in West St. Paul enters this subwatershed as well as from the Friendly Marsh, West Marie Avenue, and East Marie Avenue Drainage Subwatersheds. The predominant drainage feature in this district is Interstate Valley Creek, which runs northward adjacent to I-35E. Interstate Valley Creek discharges to the City of Lilydale and then to the Mississippi River. 4.3.2. Ivy Falls Creek Watershed (IF) The Ivy Falls Creek Watershed resides within the cities of Mendota Heights and West St. Paul. The City of West Paul has approximately 274 acres tributary to Ivy Falls Creek. The SECTION 4 Stormwater Management Plan Section 4 City of Mendota Heights WSB Project No. 1735-04 Page-7 predominant land use is single-family residential. The northern portion of the Somerset Country Club golf course lies in this watershed. Ivy Falls Creek is an intermittent stream that begins in Somerset Golf Course. The streambed drops approximately 180 feet along its 3,000-foot length from Dodd Road to TH 13, including a 50-foot drop at Ivy Falls. Because of this steep gradient, erosion has occurred along the creek. 4.3.3. Mississippi River Bluffs Watershed (MB) This watershed consists of the various small drainage routes along the Mississippi River bluffs. These drainage routes discharge water to culverts under TH 13 to the City of Lilydale. Areas that drain to either Interstate Valley Creek or to Ivy Falls Creek are not included in this watershed. The drainages in this watershed have similar features; they all include a small area above the bluffs which then drains down the bluffs to ditches and culverts along TH 13. Because of the steep slopes in this watershed, the water flows quickly and erosion and flooding problems exist in some of these drainage routes. The watershed is divided into four drainage subwatersheds. West Highway 13 Drainage Subwatershed The West Highway 13 Drainage Subwatershed runs along the south side of TH 13 from the City of Mendota Heights border with the City of Mendota east to I-35E. The drainage discharges through six culverts beneath TH 13 to Lilydale. Approximately 20 acres of this drainage subwatershed are in Lilydale. Central Highway 13 Drainage Subwatershed The Central Highway 13 Drainage Subwatershed is located between the Ivy Falls Creek and Interstate Valley Creek watersheds, south of TH 13. Discharge from this subwatershed occurs through two culverts beneath TH 13. East Highway 13 Drainage Subwatershed The East Highway 13 Drainage Subwatershed is located at the northern tip of Mendota Heights. Approximately 25 acres of West St. Paul is tributary to the district. The drainage from this subwatershed discharges to Lilydale through an 18-inch culvert under TH 13. Highway 110 Drainage Subwatershed The Highway 110 Drainage Subwatershed drains through a series of ditches and ponds before discharging to the Mississippi River via a culvert that passes through the City of Mendota. The eastern extent of this drainage subwatershed is approximately at the intersection of Highway 110 and Victoria Road. 4.3.4. Gun Club Lake Watershed (GC) This watershed is in the west part of the City and includes all of the area in Mendota Heights that is within the LMRWMO and part of the area which is within the LMRWD. This watershed has five drainage subwatersheds. SECTION 4 Stormwater Management Plan Section 4 City of Mendota Heights WSB Project No. 1735-04 Page-8 Lake Augusta Drainage Subwatershed This subwatershed consists of land that drains to Lake Augusta. Open space is the predominant land use because of the presence of Resurrection Cemetery. Industrial/office and single-family land uses are also present. Lake Augusta is landlocked, so no surface discharge occurs from the lake. Mendota Heights and the LMRWMO will work toward determining whether an outlet to Lake Augusta is necessary Industrial Park Drainage Subwatershed Most of the Industrial Park Drainage Subwatershed is zoned for industrial/office land use. The 30-acre Lake LeMay is the subwatershed’s only major water body and is located in the northwest portion. Lake LeMay discharges to the Industrial Park storm sewer system via a 30-inch pipe that crosses under Highway 55. The outlet pipe is designed such that when water levels in Lake LeMay are below the normal water level (NWL), runoff collected by the 30-inch outlet pipe flows to Lake LeMay and not to the Industrial Park. When water levels are above the NWL, flows are routed to the Industrial Park. The water from the drainage subwatersheds discharges through a 54-inch storm sewer to an open channel in a ditch. The ditch drains to a 66-inch culvert under TH 13 where it again flows in an open channel, and ultimately discharges to Gun Club Lake. With the exception of Lake LeMay, little stormwater storage is available in the Industrial Park Drainage Subwatershed. Interstate 494 Drainage Subwatershed This subwatershed district is the stretch of I-35E south of Wagon Wheel Trail. The major land use in the subwatershed is industrial/office. The runoff from this drainage subwatershed flows to the I-494 drainage system that ultimately discharges to the Minnesota River. Minnesota River Bluff Drainage Subwatershed This subwatershed consists of land with several drainage routes that discharge into the Minnesota River. All surface drainage in this subwatershed discharges to culverts under the Chicago and North Western Transportation Company railroad tracks. There are approximately 22 culverts under the 1.5 miles of railroad track bordering the subwatershed. Land use in this drainage subwatershed includes open space within Fort Snelling State Park, wooded bluff slope, industrial/office, highway, cemetery, and single- family residential. South Highway 13 Drainage Subwatershed This subwatershed is generally located along TH 13 and Highway 55, between the Minnesota River Bluff and Industrial Park Drainage Subwatersheds. This subwatershed combines its discharge flow with flows from the Industrial Park Drainage Subwatershed at the MnDOT pond located near the intersection of TH 13 and I-494. The discharge ultimately flows to Gun Club Lake. 4.4. Hydrologic Modeling Discussion There was a modeling effort completed for the 2006 LSWMP that consisted of converting the 1993 WRMP model to the more user friendly HydroCAD modeling software, and to update the model to current conditions of the City. SECTION 4 Stormwater Management Plan Section 4 City of Mendota Heights WSB Project No. 1735-04 Page-9 The 2006 HydroCAD model was updated for this 2018 SWMP to accommodate for the new National Oceanic and Atmospheric Administration (NOAA) Atlas 14 Precipitation Frequency Estimates by defining additional stage/area and overflow routes so that the 100-year Atlas 14 rainfall can be run within the model without exceeding defined storage or outlets. Table 4.3 shows the Atlas 14 rainfall depths that shall be used for project reviews and stormwater design. Additionally, drainage areas and land use descriptions were reviewed and corrected when discrepancies appeared. The updated hydrologic model is summarized in Appendix E. HydroCAD stormwater runoff hydrographs are calculated in accordance with SCS TR-20 methodology. Hydrograph routing through channels and detention basins is performed using the Dynamic-Storage-Indication method. For compliance with the MS4 permit, the City is required to develop a method to ensure that its water quality ponds function according to design. A P8 Urban Catchment Model was created and the results can be found in Appendix E. Table 4.3 Atlas 14 Rainfall Depths Storm Event Rainfall Depth (Inches) 2-year, 24-hour 2.81 10-year, 24-hour 4.19 100-year, 24-hour 7.47 SECTION 5 Surface Water Management Plan Section 5 City of Mendota Heights WSB Project No. 1735-04 Page-1 5. GOALS AND POLICIES 5.1. Purpose The primary goal of Mendota Heights’ SWMP is to bring the City into statutory compliance and provide a framework for effective stormwater management. This includes guiding redevelopment activities and identifying and implementing retrofits to the existing system. These retrofits consist of both projects and programs. Additionally, the plan provides clear guidance on how Mendota Heights intends to manage surface water in terms of both quantity and quality. The goals of Mendota Heights’ SWMP are consistent with the goals of the LMRWMO and the LMRWD, while addressing the more specific and changing needs of the City. This plan is an update to the 2006 Water Management Plan and the goals of this plan were established in accordance with the guidelines contained in Minnesota Statutes 103B and Minnesota Rules 8410. A general priority of the City is to cooperate, collaborate, and partner with other entities, such as LMRWMO, LMRWD, and the MPCA as much as possible as the City implements this plan. Cooperation, collaboration, and partnering results in projects that are less likely to conflict with the goals of the affected entities, are better able to meet long-term goals, and are generally more cost-effective. In addition to the goals and policies contained in this section, the City will annually review and update its SWPPP to effectively manage its stormwater system and be in conformance with the NPDES MS4 Program. Refer to Appendix B for the most recent version of the City SWPPP. 5.2. Background The City completed its first comprehensive plan in 1960. The City has most recently updated its comprehensive plan in 2010 with its 2030 Comprehensive Plan. The 2030 Comprehensive Plan reiterated the goals of the previous plan, while also strengthening the City’s traditions and development philosophy. Open spaces and parks are deeply ingrained in the City of Mendota Heights and its comprehensive plan, and surface waters play a large role in many of those assets. Specific to the goals and policies of this SWMP is the following policy statement from the 2030 Comprehensive Plan: “Work with local and regional partners to conserve, protect and enhance the region’s vital natural resources.” The 2018 Mendota Heights SWMP expands upon the goals and objectives provided in the 2030 Comprehensive Plan, the 2006 LSWMP, and the updated Third Generation LMRWD and LMRWMO Water Management Plan. 5.3. City of Mendota Heights SWMP Goals and Policies 5.3.1.Water Quantity 5.3.1.1. Goal Prevent flooding from surface flows while reducing, to the greatest extent practicable, the public capital expenditures necessary to control excessive volumes and rates of runoff. 5.3.1.2. Policies 1. All designs must use NOAA Atlas 14 Precipitation Frequency Data in stormwater design calculations and modeling. SECTION 5 Surface Water Management Plan Section 5 City of Mendota Heights WSB Project No. 1735-04 Page-2 2. Trunk storm sewers shall be designed with capacity for 100-year ponded outflows plus 10-year directly connected flows. 3. In addition to the 10-year and 100-year ponded flow primary capacity, the conveyance system shall provide capacity in excess of the 100-year event in the form of overland overflow routes or adequate surface storage volume. This surface storage volume consists of storage in street low points, within ditches, or in other transient ponding areas. 4. Proposed runoff from development and redevelopment projects shall meet or decrease peak discharge rates for the 10-year and 100-year storm events. Additionally, capacity of downstream drainage systems must be considered, and shall not exceed existing capacities. 5. Detention basins shall be designed with capacity for the critical 100-year event. At a minimum, detention basins should maintain existing flow rates for the 2-, 10- , and 100-year 24-hour rainfalls. 6. The maximum duration for rainfall critical event analysis shall be 24 hours except in cases where basins are landlocked, where back-to-back 24-hour events and the 10-day, 7.2-inch runoff event shall also be used. In all cases a hydrograph method of analysis should be used. For the 24-hour rainfall event or back-to- back 24-hour rainfall events, the Midwest and Southeast 3 (MSE3) distribution, published by the Natural Resources Conservation Service, is recommended. For shorter duration critical events, other distributions may be used with the approval of the City Engineer. Regarding Water Quantity policies 1, 2, 3, 4, and 5—for systems designed and implemented prior to the 1993 WRMP, conveyance capacity and storage requirements may not meet these requirements. These policy statements in no way imply that the City intends to unilaterally upgrade these systems. 7. All drainage system analyses and designs shall be based on proposed full development land use patterns. 8. The amount of impervious surface increase on projects shall be reduced to the greatest extent possible for development and redevelopment projects in accordance with Low Impact Development (LID) techniques. A narrative shall be provided that addresses the consideration of LID techniques in development and redevelopment impervious surface design. 9. Intercommunity water resources issues planning shall consider alternative solutions: a) All drainage studies or feasibility studies, whether by a watershed organization or municipality, leading to projects in a subwatershed with an intercommunity drainage issue shall consider the impact of the project on the drainage issue and shall consider the total intercommunity project cost. b) Except in emergencies, no solutions or partial solutions to intercommunity drainage issues shall be implemented without prior completion of a feasibility study of options and adoption of a preferred option by the applicable watershed organization. SECTION 5 Surface Water Management Plan Section 5 City of Mendota Heights WSB Project No. 1735-04 Page-3 10. The following items shall be considered in the management of landlocked basins: a) The flood levels established for landlocked basins shall take into consideration the effects of water level fluctuations on trees, vegetation, erosion, and property values. Steeply sloped shorelines subject to slope failure and shoreline damage should not be in contact with floodwaters for extended periods of time. b) The capacity of proposed outlets to formerly landlocked basins should not be so small as to cause extended duration of High Water Levels (HWLs) that would result in damage to upland vegetation. c) Only the existing tributary area may discharge to a landlocked basin, unless a provision has been made for an outlet from the basin or the right to augmented storage within the basin has been secured through purchase or easement, except in cases where adverse impacts to vegetation would occur. The form of outlet may range from temporary pumps to gravity storm sewers. The outlet shall be implemented before increased water levels are likely to affect vegetation, slope stability, or property values. d) Critical event analysis of landlocked basins shall include the 10-day, 7.2- inch runoff event and back to back 24-hour, 100-year events. 11. When development occurs adjacent to a landlocked basin and the basin is not provided an outlet, freeboard should be determined based on one of three methods (whichever provides for the highest freeboard elevation): a) Three feet above the HWL determined by modeling back to back 100- year, 24-hour events; b) Three feet above the highest known water level; or c) Five feet above the HWL determined by modeling a single 100-year, 24- hour event. When modeling landlocked basins, the starting water surface elevation should be the basins Ordinary High Water elevation, which can be determined through hydrologic modeling or, in the case of a DNR regulated basin, from a DNR survey. Additionally, a continuous simulation of average annual rainfall conditions will also provide insight into whether significant, adverse impact to vegetation would occur due to development around the landlocked basin. 12. For basins with a suitable outlet, freeboard will be two feet above the HWL determined by modeling the 100-year critical event. Emergency overflows that are a minimum of one and a half feet below the lowest ground elevation adjacent to a structure should also be provided. 13. Adjacent to channels, creeks, and ravines freeboard will also be two feet from the 100-year critical event elevation. 14. Work with the DNR and watershed organizations on cooperative and collaborative projects in the public lands below the river bluffs. SECTION 5 Surface Water Management Plan Section 5 City of Mendota Heights WSB Project No. 1735-04 Page-4 Discussion: This policy is essentially a blanket policy covering the many subject areas for which goals have been developed. The City of Mendota Heights understands that its drainage system has the potential to damage ecologically sensitive areas below the bluffs in Fort Snelling State Park. The City envisions the State or watershed organizations as the lead on such projects. 15. New storm sewers and open channels shall be designed using a technical method approved by the MPCA Stormwater Manual such as the Rational Method or HydroCAD . Runoff Coefficient “C” shall be in accordance with the guidelines provided in the MnDOT’s Drainage Manual. 16. A hydrograph method based on sound hydrologic theory shall be used to analyze runoff rates and high water levels for proposed development and redevelopment projects. 17. Water quality treatment ponds (wet ponds) shall be designed in accordance with National Urban Runoff Program (NURP) standards. 18. Drainage and utility easements shall be dedicated over newly constructed stormwater management features (volume, rate control, and water quality treatment infrastructure) including but not limited to ponds, infiltration basis, rain gardens, underground storage and treatment devices, and tree trenches. Additionally, drainage and utility easements shall be dedicated for redeveloped stormwater management features and existing stormwater management features on redevelopment sites. Refer to the most up to date LMRWD and LMRWMO Rules on their websites. 5.3.2.Water Quality 5.3.2.1. Goal Work with LMRWMO, LMRWD, and neighboring communities to maintain and/or enhance the water quality of Mendota Heights’ lakes, wetlands, streams, and other water resources. 5.3.2.2. Policies 1. Given that the soils underlying the City have higher than typical infiltration capacity, infiltration is the preferred means of protecting water quality. Mendota Heights requires that stormwater infiltration facilities include sufficient water quality pretreatment (to NPDES and watershed standards) to preserve the function of these facilities. Wellhead protection areas must also be reviewed when considering infiltration. 2. Apply the MPCA’s Minimal Impact Design Standards (MIDS) to new developments within the City. a) All new developments that create new impervious surfaces shall endeavor to retain 1.1 inches of runoff from the net increase of impervious area. The City of Mendota Heights recommends consideration of the Flexible Treatment Options Approach through MIDS. However, the City does not adopt MIDS. As an MS4, the City of Mendota Heights is required to achieve no net increase in loadings for TSS, TP, and water volume as a result of development and redevelopment activities. The City does not believe it can uniformly expect these results on individual developments and would rather manage this responsibility across the entirety of the MS4 and not on an individual SECTION 5 Surface Water Management Plan Section 5 City of Mendota Heights WSB Project No. 1735-04 Page-5 development basis. This is why practical implementation and not adoption of MIDS is preferred. b) If a development or redevelopment site exceeds 1 acre of disturbance and is not able to retain 1.1 inches of runoff, they shall be required to meet a 50% phosphorus reduction based on existing conditions. 3. Utilize, where feasible and possible, regional stormwater detention facilities to enhance water quality by removing sediment and nutrients from runoff. 4. Support water quality monitoring efforts being undertaken by the LMRWMO and LMRWD. 5. Wherever practical, new water quality ponds will be designed and constructed to provide a water quality treatment volume equivalent to the runoff from a 2.5-inch rainfall event, or the requirements of the NPDES construction site permit, whichever leads to higher treatment capacity. In some cases, other BMPs will be used in conjunction with water quality ponds. In such cases performance of the water quality system shall be no less than the performance of a single pond designed under the 2.5-inch criterion. 6. Newly constructed ponds shall include an outlet design allowing for extended detention of the 1- to 5-year rainfall event. The hydrograph duration for pond discharge should extend a minimum of 24 hours for events within the 1- to 5-year range. 7. Outlet skimming will be required in all ponds. Skimming shall occur for up to the 5- year, 24-hour event. 8. Utilize the MPCA’s Twin Cities Metropolitan Area Chloride Management Plan to reduce chloride pollution by effectively managing salt use. Refer to LMRWD and LMRWMO Rules on the watersheds’ websites for the most up to date version. 5.3.3.Recreation and Fish and Wildlife 5.3.3.1. Goal Protect and enhance fish and wildlife habitats, water recreational facilities, and water resource aesthetics. 5.3.3.2. Policies 1. The neighborhood and regional benefits of wildlife habitat and aesthetics should be considered in any proposal to alter or eliminate wetlands, understanding that wetland elimination without mitigation is precluded by state law and understanding that even mitigated wetland impacts must meet strict sequencing guidelines. 2. The City will review inlets and outlets for aesthetics. 3. Mendota Heights shall seek to coordinate with the DNR regarding development of DNR public waters and public water wetlands. Notwithstanding ordinance provisions both existing and future that control development of shoreland areas, the City will seek DNR comments on development proposals adjacent to DNR public waters and public water wetlands. As part of its implementation plan the City will adopt a shoreland protection ordinance. SECTION 5 Surface Water Management Plan Section 5 City of Mendota Heights WSB Project No. 1735-04 Page-6 4. Water resources shall be maintained in such a manner as to preserve or restore their intrinsic aesthetic qualities and wildlife habitat. 5.3.4.Enhancement of Public Participation; Information and Education 5.3.4.1. Goal Inform and educate the public concerning urban stormwater management and the problems pollutants cause if allowed to enter into water resources. 5.3.4.2. Policies 1. Enact a public education program based on the following objectives to reduce stormwater pollution: Raise awareness of the problem and solutions Promote community ownership of the all surface water features Recognize responsible parties and actions to date Merge public feedback into program execution 2. Enact a public education program to satisfy the minimum control measures identified in the City’s NPDES permit. 3. Coordinate education efforts with the watershed organizations so that redundant efforts are avoided. 4. Report progress of meeting SWMP goals to LMRWMO and LMRWD annually. 5.3.5.Groundwater 5.3.5.1. Goal Maintain and improve groundwater quality and promote groundwater recharge. 5.3.5.2. Policies 1. To the extent that Wellhead Protection Plans (WHPPs) identify areas of groundwater recharge that require protection, the City shall work with the MDH and neighboring communities in developing adequate protection measures 2. Surface water management improvements in likely recharge areas and areas of high vulnerability to chemical or petroleum spills shall be designed to assist groundwater protection. Practically, this means infiltration shall not be considered in developments that include the potential for these types of spills. Note: The City of Mendota Heights obtains its potable water from the St. Paul Water Utility. The neighboring communities of Eagan and Inver Grove Heights have separate municipal water systems, but neither community has identified a 10-year well capture zone that overlaps into Mendota Heights. Inver Grove Heights has yet to prepare a WHPP so it remains to be seen whether Mendota Heights will be affected by a 10-year capture zone for Inver Grove Heights’ wells. Since Mendota Heights is not an active participant in the MDH Wellhead Protection Program, the City will have to rely on MDH and neighboring communities to identify 10-year capture areas. To the extent that future analyses identify these areas within Mendota Heights, the City will then use its subdivision authority to properly regulate these areas. 5.3.6.Wetlands 5.3.6.1. Goal SECTION 5 Surface Water Management Plan Section 5 City of Mendota Heights WSB Project No. 1735-04 Page-7 Protect and preserve wetlands through administration of the WCA. 5.3.6.2. Policies 1. Act as the local government unit responsible for enforcing the WCA enacted in1991. 2. Discourage wetland disturbance. Wetlands must not be drained or filled, wholly or partially, unless replaced by restoring or creating wetland areas of equal public value, as permitted by the WCA. 3. Up to one-half acre of “debit” wetland (filled or drained) will be allowed to be replaced through wetland “credit” in a bank which is located outside of Mendota Heights’ city limits, but State and County governments are exempt from this policy (M.S. 103G.222 (e)). 4. Restrict clearing and grading within close proximity of the wetland boundary to provide for a protective buffer strip of natural vegetation to promote infiltration of sediment and nutrients. In the event that grading occurs close to the wetland boundary, native plant materials shall be reestablished as a buffer strip. 5. Require that a wetland assessment be prepared for any project that includes a wetland. Minnesota Routine Assessment Methodology for evaluating wetland function (current version 3.0 but as updated in the future) is the required method of assessment. 6. Runoff shall not be discharged directly into wetlands without pretreatment of the runoff. 7. Require an average 15-foot buffer of natural vegetation above the 100-year HWL or NWL around lakes, streams and wetlands. Refer to LMRWMO and LMRWD Rules and Standards on their websites for Wetland Management Policies within the City. The 2006 LSWMP included a Wetland Management Plan. The Wetland Management Plan was not updated as a part of this SWMP, but the 2006 version can be found in Appendix F. 5.3.7.Erosion and Sediment Control 5.3.7.1. Goal Prevent, to the extent possible, sediment from construction sites from entering the City’s surface water resources and control the erosion from drainage ways within the City. 5.3.7.2. Policies The City’s Stormwater Management, Illicit Discharge, Soil Erosion and Sedimentation Ordinance includes temporary and permanent erosion and sediment control standards that meets or exceeds standards contained in the NPDES construction site permit and watershed organization plans. 5.3.8.Floodplains 5.3.8.1. Goal Control development in floodplains and floodways including those subject to FEMA studies (Mississippi and Minnesota Rivers) and those that are not regulated by FEMA studies like ponds, wetlands, lakes, and channels within the City limits. SECTION 5 Surface Water Management Plan Section 5 City of Mendota Heights WSB Project No. 1735-04 Page-8 Note: Title 12, Chapter 1, Article D, Section 11 (12-1D-11) of the Mendota Heights City Code defines permitted uses within Floodway and Floodplain Districts. Chapter 2 controls development adjacent to wetlands lakes and channels that are not a FEMA-designated floodplain or floodway. Additionally, the City will be preparing a shoreland ordinance, similar to the Minnesota DNR model ordinance that will further define limitations to development along shoreland and non-federally regulated floodplain areas. 5.3.9.Mendota Heights NPDES Permit 5.3.9.1. Goal Operate and manage the City’s surface water system consistent with best current practices and the City’s NPDES Permit. 5.3.9.2. Policies 1. Projects to correct existing deficiencies, to the extent they are identified, will be prioritized as follows: Projects intended to reduce or eliminate flooding of structures in known problem areas. Projects intended to improve water quality in the City’s lakes. Projects intended to retrofit water quality treatment into developed areas. Projects intended to reduce maintenance costs. Projects intended to restore wetlands and habitat. 2. The City will actively inspect and properly operate, maintain, and repair its stormwater system. The City will follow a regular inspection, cleaning, and repair schedule. Frequency of maintenance will be event-based and informed by experience and inspection history. The City’s SWPPP outlines the frequency of these activities. Section 5 of this Plan provides some guidelines on pond maintenance and inspection cycles, but the SWPPP will remain the definitive source on the City’s intended maintenance and inspection schedules 3. The City will follow best management practices on its own lands and for its own projects including street reconstruction projects in accordance with the NPDES construction site permit and the City’s NPDES MS4 Permit. 5.3.10.Financial Management 5.3.10.1. Goal Ensure that the costs of the surface water system are equitably distributed. 5.3.10.2. Policies 1. The City will periodically update its stormwater utility rate structure to accomplish the following: Meet the requirements of its NPDES permit. Provide for the maintenance of ponds and outfall structures. Conduct repairs to the system. Update its system planning efforts. Implement rainwater gardens or other water quality retrofits. 2. Use other funding sources including land sale proceeds, partner with watershed organizations, State Aid funds, grants, among other things to pay for the implementation activities, when available and appropriate. SECTION 5 Surface Water Management Plan Section 5 City of Mendota Heights WSB Project No. 1735-04 Page-9 5.3.11.Individual Sewage Treatment Systems (ISTS) 5.3.11.1. Goal Ensure that ISTS that remain in the City do not constitute an environmental hazard. 5.3.11.2. Policy Where ISTS are known to be failing and pose an imminent environmental hazard, the City will take the necessary steps to see that these systems are repaired or eliminated. Background: Within Mendota Heights are approximately 40 ISTS. The City has an ISTS ordinance equivalent to that of Dakota County whereby property owners provide pump and inspection records to the City. SECTION 6 Surface Water Management Plan Section 6 City of Mendota Heights WSB Project No. 1735-04 Page-1 6. IMPLEMENTATION PROGRAM 6.1. General The Implementation Plan section of the Mendota Heights SWMP describes those activities and programs the City might develop to improve its surface water management program. Since Mendota Heights is largely developed, capital outlay for the trunk sewer system has already occurred so future outlay will be for upgrades and replacement. Typically, costs for upgrade and replacement would be borne by either the stormwater utility fund or would be recovered through direct assessment. Given this, a typical financing mechanism developed in most SWMPs, an area charge, is not a part of the Mendota Heights SWMP. Table 6.1 contains a comprehensive list of the MS4 activities and projects, programs, and studies that make up the City of Mendota Heights implementation program for the next seven years (2017-2023). The program was developed by evaluating the requirements in the MS4 permit (see MS4 SWPPP Application for Reauthorization in Appendix B), reviewing existing information (Section 2), identifying potential and existing problems (Section 4), reviewing goals and policies (Section 5), and then assessing the need for programs, studies, maintenance, or projects. Costs were estimated, possible funding sources were identified, and a schedule was developed to complete the implementation activities. It is anticipated these tables will be updated/revised on a yearly basis. This section also includes: An overview of the City’s NPDES permit A discussion of operation and maintenance procedures and strategies An outline of an education program Financial considerations for the stormwater utility A section referencing applicable design standards for stormwater management A section on watershed implementation priorities Implementation priorities for the City 6.2. Implementation Priorities The implementation components listed in Table 6.1 were prioritized to make the best use of available local funding, meet MS4 Permit requirements, address existing stormwater management problems, and prevent future stormwater management problems from occurring. The City's implementation plan reflects its responsibility to protect the public health, safety, and general welfare of its citizens by addressing problems and issues that are specific to the City of Mendota Heights. 6.3. Operation and Maintenance 6.3.1.Activities A stormwater system is a major investment for the City of Mendota Heights—both in terms of initial capital cost and in terms of ongoing maintenance costs—with meeting ongoing maintenance costs being the City’s current challenge. Typically, system maintenance is funded by the City’s stormwater utility and through the general fund. The City’s stormwater system maintenance responsibilities include the following: Street sweeping Cleaning of sump manholes and catch basins SECTION 6 Surface Water Management Plan Section 6 City of Mendota Heights WSB Project No. 1735-04 Page-2 Repair of catch basins and manholes Assessing pipe condition (typically by televising) Inspection of storm sewer inlet and outlet structures Pond mowing and other vegetation maintenance Excavation of accumulated sediments from ponds The City has maintained its pipe system for decades and staff has a strong grasp on the costs associated with this. As new development brings more ponds (and other BMPs) into the system, the City will find that maintenance becomes an increasingly large portion of both staff time and the overall maintenance budget. It is important to quantify the extent of this future commitment so that the funds necessary for pond maintenance activities can be collected via the storm water utility. The management of stormwater ponds is facilitated by creation of a geographical information system (GIS) database for all stormwater system infrastructure. The City is continuing to map its system in this software by providing data for all pipes 12 inches and larger, most private and government pipes, and pond numbering. This move to GIS to track stormwater system infrastructure represents a strong step toward an interactive mapping system. Ultimately, via its stormwater management database the City could reference its maintenance records, videotapes, and maintenance costs for the stormwater system using interactive mapping. The City’s NPDES permit calls for an incremental approach to mapping the existing storm sewer system. 6.3.2.Stormwater Basins Stormwater basins represent a sizable investment in the City's drainage system. General maintenance of these facilities helps ensure proper performance and reduces the need for major repairs. Periodic inspections are performed to identify possible problems in and around the basin. Inspection and maintenance cover the following: Basin outlets Basin inlets Side slopes Illicit dumping and discharges Sediment buildup Basin Outlets A key issue with stormwater basins is ensuring that the outlets perform at design capacity. Inspection and maintenance of basin outlets address the following: The area around outlets is kept free and clear of debris, litter, and heavy vegetation. Trash guards are installed and maintained over all inlets to prevent clogging of the downstream storm sewer. Trash guards are inspected at least once a year, typically in the spring, to remove debris that may clog the outlet. Problem areas are addressed more frequently, as required. Emergency overflow outlets are provided for all ponds when possible. These are kept clear of debris, equipment, and other materials and properly protected against erosion Basin Inlets Inspection and maintenance of basin inlets address the following: SECTION 6 Surface Water Management Plan Section 6 City of Mendota Heights WSB Project No. 1735-04 Page-3 Inlets are inspected for erosion. o Where erosion occurs near an inlet, energy dissipaters or riprap are installed. Inlets are inspected for sediment deposits, which can form at the inlets due to poor erosion practices upstream. o Where sediment deposits occur, these are removed to ensure design capacities of storm sewers entering the basin are maintained. Side Slopes Inspection and maintenance of basin side slopes address the following: Side slopes are kept well-vegetated to prevent erosion and sediment deposition into the basin. Severe erosion alongside slopes can reduce the quality of water discharging from the basin and require the dredging of sediments from the basin. Noxious weeds are periodically removed from around basins. Some basins located in highly developed areas require mowing. If mowing is performed, a buffer strip of 25 feet or more adjacent to the NWL is typically maintained. This provides filtration of runoff and protects wildlife habitat. Illicit Dumping and Discharges Inspection for and maintenance because of illicit dumping and discharges into basins address the following: Basins are periodically inspected for evidence of illicit dumping or discharges. The most common of these is dumping of yard waste into the basin. Where found, illicit material is removed, and signs are posted as needed prohibiting the dumping of yard waste. Water surfaces are inspected for oil sheens. These can be present when waste motor oil is dumped into upstream storm sewers. Skimmer structures are installed as needed at outlet structures to prevent oil spills and other floatable material from being carried downstream. Skimmer structures are periodically inspected for damage, particularly from freeze- thaw cycles. Sediment Buildup Inspection for and maintenance because of sediment buildup in basins address the following: Basins are inspected to determine if sediment buildup is causing significant loss of storage capacity from design levels. Excessive sediment buildup significantly reduces the stormwater treatment efficiency of water quality ponds. Sediment removal is performed where excessive sediment buildup has occurred. As a general guideline, ponds require dredging every 15 to 20 years. When effective, forebays are provided these may require more frequent cleaning (approximately five to seven year cycles) but tend to produce less material and have the effect of extending the maintenance cycle of ponds to as much as every 30 years. 6.3.3.Sump Manholes and Sump Catch Basins Sump manholes and sump catch basins are included in storm sewer systems to collect sediments before they are transported to downstream waterbodies. These structures SECTION 6 Surface Water Management Plan Section 6 City of Mendota Heights WSB Project No. 1735-04 Page-4 keep sediments from degrading downstream waterbodies. Once sediments are transported to a lake or pond, they become much more expensive to remove. Sediments originate primarily from road sanding operations, although construction activity and erosion can also contribute. Since these structures are designed to collect these sediments, they are routinely cleaned to provide capacity for future sedimentation. Suction vacuum equipment is typically used to clean out the structure. 6.3.4.Storm Sewer Inlet Structures To fully utilize storm sewer capacity, inlet structures are kept operational in order to get runoff into the system. All efforts are made to keep catch basins and inlet flared ends free of debris and sediments so as not to restrict inflow and cause flood damage. Leaf and lawn litter are the most frequent cause of inlet obstructions. On a routine basis, City staff visually inspects inlet structures to ensure they are operational. 6.3.5.Open Channels and Ravines Overland flow routes constitute an important part of the surface water drainage system. Open channels are typically vegetated and occasionally lined with more substantial materials. The lined channels typically require little or no maintenance. Vegetated channels are periodically inspected and maintained, as high flows can create erosion within the channel. Eroded channels can contribute to water quality problems in downstream waterbodies as the soil is continually swept away. If not maintained, the erosion of open channels would accelerate and repairs would become increasingly costlier. The erosion of channels is accelerated when the channels are at steep gradients and are used for conveying urban stormwater. 6.3.6.Piping System The storm sewer piping system constitutes a multimillion dollar investment for the City. The City performs a comprehensive maintenance program to maximize the life of the facilities and optimize capital expenditures. The following periodic inspection and maintenance procedures are followed: Catch basin and manhole castings are inspected and are cleaned and replaced as necessary. Catch basin and manhole rings are inspected and are replaced and/or re-grouted as necessary. Catch basin and manhole structures are inspected and are repaired or replaced as needed. Pipe inverts, benches, steps (verifying integrity for safety), and walls are checked. Cracked, deteriorated, and spalled areas are grouted, patched, or replaced. Storm sewer piping is inspected either manually or by television to assess pipe condition. Items looked for include root damage, deteriorated joints, leaky joints, excessive spalling, and sediment buildup. The piping system is programmed for cleaning, repair, or replacement as needed to ensure the integrity of the system. 6.3.7.De-Icing Practices Minnesota receives approximately 54 inches of snow during a typical year. This requires a large amount of de-icing chemicals (primarily salt) to be applied to roads and sidewalks each winter. SECTION 6 Surface Water Management Plan Section 6 City of Mendota Heights WSB Project No. 1735-04 Page-5 Estimates indicate that 80 percent of the environmental damage caused from de-icing chemicals is a result of inadequate storage of the material (MPCA 1989). Improper storage as well as overuse of salt increases the risk of high chloride concentrations in runoff and groundwater. High chloride concentrations can be toxic to fish, wildlife, and vegetation. The following procedures are used for storing de-icing chemicals in the City: 1. De-icing material and sand is stored in waterproof sheds. When and where this is not possible, stockpiles are covered with polyethylene and placed on impervious surfaces. No salty runoff water shall leave salt sheds 2. Road de-icing stockpiles are not located near municipal well areas or in other sensitive groundwater areas. The City shall encourage businesses within the City to apply the MPCA’s Twin Cities Area Chloride Management Plan, particularly the following procedures: Promote businesses using the Winter Maintenance Assessment tool (WMAt), a web- based tool maintained by the MPCA that helps identify opportunities to reduce salt use and save money Encourage businesses to use contracts that do not bill by the weight of salt used in order to reduce over-use. Re-use winter truck wash water for brine making, and reduce the amount of salt on a truck prior to entering the wash Create a chart of items to investigate that may reduce salt use/waste. 6.3.8.Street Sweeping Street sweeping is an integral part of the City’s effective surface water management system. It greatly reduces the volume of sediments that have to be cleaned out of sump structures and downstream waterbodies. The City has a street sweeping policy that includes at least one sweeping operation per year. Spring sweeping begins in either late March or early April after the risk of later snowfall has passed and targets sand left from winter sanding operations. Occasional fall sweeping occurs after leaf fall. Mendota Heights does not allow residents to rake leaves into the street for municipal pick up. Dakota County and the City encourage residents toward composting their yard waste. If residents desire to have yard waste removed by their private hauler, then compostable bags or reusable containers are required. Alternately, there are composting sites within Dakota County where yard waste can be brought for a fee. Overall the City’s approach to minimizing organic matter entering its stormwater system greatly reduces the incidence of inlet blockages and protects the water quality of downstream waterbodies. The objective of the City’s street sweeping and de-icing programs is to minimize impacts from leaf litter, sand, salt, and other debris on the surface waters of the City. 6.3.9.Detection of Illicit Connections Mendota Heights has modified its ordinance to prohibit the dumping of hazardous material into the stormwater system. During routine inspection for inlet grates, outfalls, and other portions of the stormwater system, City staff also look for evidence of illicit discharge, dry weather flow (indicating possible sanitary sewer connections), sedimentation, and other non-point source pollution problems. SECTION 6 Surface Water Management Plan Section 6 City of Mendota Heights WSB Project No. 1735-04 Page-6 The City has started the process of mapping its storm sewer outfalls and integrating this mapping with inspection data. This effort will be concurrent with the overall storm sewer mapping effort required by the City’s NPDES permit. 6.4. Education and Outreach 6.4.1.General Education can play an important role in any effort to implement a surface water management program like the one outlined in this SWMP. The objectives of an education effort are different, depending on the target audience. In general, the target audience for this education program is City staff, residents, and the development community. The following sections describe why education of each of these groups is important and presents educational methods that may be used for each audience. One of the more important aspects of education and outreach is close coordination with watershed organizations so that redundant efforts are avoided. The City should also work to raise the profile of its watershed organizations by including articles on watershed activities in its informational materials. One simple step toward stronger city/watershed partnership is providing a link to each watersheds website on the city website. 6.4.2.City Staff City staff have a wide range of responsibilities for implementing this plan. These include: Implementing street sweeping and spill response programs. Implementing deicing education and outreach for residents and business owners, and by encouraging involvement in the MPCA’s Twin Cities Metropolitan Area Chloride Management Plan by using their WMAt. Maintaining detention basin/stormwater management pond performance and system operability. Planning for and managing of projects to enhance pollutant removal performance, wetland quality, among other items. Carrying out grounds maintenance of City-owned lands/facilities in a way that sets a good example for residents. Utilizing BMPs in application of ice control material. Application of BMP policies and regulations to new and redevelopment projects. Planning and delivering education programs. Working out cooperative arrangements with regulatory and non-regulatory organizations to achieve SWMP objectives. Assisting the City Council in the application of the SWMP policies. Because these responsibilities involve many different levels, City staff members are trained to have a basic understanding of the SWMP, including: A description of the major stormwater management issues (including known stormwater management problem areas, stormwater management expectations for new and re-development projects, incorporation of stormwater mitigation into capital improvement projects, and regulatory jurisdictions). The objectives and the general approach outlined in the SWMP for resolution of these issues. The responsibilities of the different work units in implementing the SWMP. The information the SWMP provides. SECTION 6 Surface Water Management Plan Section 6 City of Mendota Heights WSB Project No. 1735-04 Page-7 Identification of in-house experts. This information is disseminated in presentations at staff meetings, internal newsletters, and internal memos. As part of its NPDES permit, the City has also made a commitment to continuing education for staff in stormwater management. This will take the form of attendance at conferences and workshops. As part of the SWMP effort, staff will also be trained in the use of the City’s stormwater management model. 6.4.3.City Residents In order to obtain the necessary political and economic support for a successful SWMP implementation, it is vital to inform City residents about basic stormwater management and water quality concepts, policies and recommendations in the SWMP, and the progress of stormwater management efforts. Through the City’s quarterly newsletter, the Heights Highlites, the City keeps residents informed of stormwater and other environmental issues particularly regarding volunteer opportunities, proper lawn care practices, and recycling and hazardous waste management information. The City website is a clearing house for information on stormwater management and will be updated to provide stormwater management articles, contact numbers for reporting illicit discharges, and other stormwater related complaints. In the near term, the City will also be providing educational brochures for residents in the City Hall lobby. These brochures will most often be from other organizations but may also be produced by the City. The City has incorporated innovative stormwater management practices into both municipal and private development projects. In the future, the City will use these projects to highlight the benefit of certain stormwater management practices. It is important that residents know about these projects (including how they were funded) so that they have an awareness that the City is working for the public interest in protecting high priority resources and that dedicated financial resources such as revenue from the stormwater utility are being put to work. The City and Dakota County co-sponsor a Wetland Health Evaluation Program which samples and documents the plant, frog, and invertebrate communities found in local wetlands following techniques developed by the MPCA. Information from this survey is available to City residents on the MPCA website. The City partners with the Metropolitan Council Environmental Services Lake Monitoring and Citizen-Assisted Monitoring Program (CAMP) program, in which residents voluntarily monitor lakes, contributing to a comprehensive database that allows cities, counties, and watershed management organization to better manage and protect these lakes. 6.4.4.Developers The SWMP is designed to provide the official policy direction that City staff and the City Council desire to guide stormwater mitigation for new and redevelopment projects. New construction in Mendota Heights is limited since there is limited land left to develop. Redevelopment, though, will likely occur on a regular basis. The information contained within this plan is disseminated to developers and their SECTION 6 Surface Water Management Plan Section 6 City of Mendota Heights WSB Project No. 1735-04 Page-8 consulting engineers as early as possible in the development review process. In this way, developers know what is expected of them and can consider the requirements in their initial assessments of the site as well as incorporate the necessary BMPs in any subsequent designs. Much of the necessary information is disseminated to the developers in an information packet as part of the development submittal information they receive from the City. While dissemination of information is valuable, there is no substitute for a meeting between key City staff and the developer as early as possible in the review process. This helps define expectations for submittals, clarify regulatory compliance issues, and provide additional detailed guidance. Developers are encouraged to do this as soon as possible after they have reviewed the SWMP information and thought about how it applies to their site. 6.5. Financing and the Stormwater Utility 6.5.1.Current Status – Summary The City of Mendota Heights implemented a stormwater utility in 1993. The current quarterly residential charge is $12.00 per residential unit and according to Table 6.2 for other land uses. The quarterly residential charge is expected to increase to $16.50 per residential unit in 2018. Table 6.2 Storm Water Utility Rates Property Type Current Rate $/Acre Business/Industrial $121.80 E 1 acre $60.90 < 1 acre Cemetery/Golf $10.15 Institutional $40.60 6.5.2.The Stormwater Utility into the Future To ensure that Storm Water Utility (SWU) funding keeps pace with increase in municipal maintenance responsibilities, the City should plan for the costs to conduct periodic pond maintenance. Limited data on maintenance activities has been developed by watershed management organizations. A review of this data suggests an annual maintenance budget of $1,250 per acre-foot of wet volume or $4,350 per acre of surface at NWL. Either parameter is relatively easy to track. This $1,250 per acre-foot maintenance item can be translated into a per household cost by virtue of the fact that one acre-foot is sufficient pond wet volume for 20 acres of residential development. Assuming two and a half units per gross acre, then $1,250 per year is spread among 50 units or $25 per unit per year. Maintenance activities that involve the disposal of stormwater pond sediment have become a high cost project due to the presence of chemicals such as polycyclic aromatic hydrocarbons (otherwise known as PAHs) in stormwater runoff. The City will continue to follow guidance from the MPCA on this issue, but it is anticipated that costs for stormwater pond maintenance activities will increase in the future. The current residential rate is $12.00 per unit per year. The current charges provide approximately $150,000 per year in revenue of which only a fraction has been used for SECTION 6 Surface Water Management Plan Section 6 City of Mendota Heights WSB Project No. 1735-04 Page-9 pond maintenance. As the City’s maintenance responsibilities grow the stormwater utility funding also needs to grow to keep pace. Mendota Heights is a regulated MS4 under the Phase II NPDES Permit. There is a cost associated with preparing an NPDES permit and the associated SWPPP. Some estimate cities the size of Mendota Heights will spend $50,000 every five years for permit preparation. For Mendota Heights, it is reasonable to assume that $10 per household will be spent every five years – adding $2 per year to the individual household’s stormwater utility bill. The NPDES permit and SWPPP commit the City to certain activities, including capital projects, for the purpose of improving the quality of the City’s stormwater discharge. The USEPA has estimated that the financial commitments that City’s will make may total $10 per household per year while others place this figure at $20. Since many of the activities identified by the SWPPP may already be funded (like street sweeping and pond maintenance) the $20 figure is probably too high. For the purposes of planning increases in SWU collection, Table 6.3 summarizes the additional stormwater utility charges identified above. Table 6.3 Future Storm Water Utility Funding Item Annual Charge to Single Residential Unit Quarterly Charge to Single Residential Unit Current commitments $18.20 $4.50 Future pond maintenance $32.50 $8.10 NPDES permit and SWPPP $2.60 $0.65 NPDES permit compliance $13.00 $3.25 Total $66.30 $16.50 6.6. Ordinance Implementation The City of Mendota Heights has updated their ordinance to include: Stormwater Management Illicit Discharge Soil Erosion and Sedimentation This will be the City’s method of instituting their site review and permitting process, and includes the submission requirements, review procedure, and enforcement policies. By incorporating site review and comments on temporary and permanent erosion control along with illicit discharge and stormwater management, there is no need to have a separate grading permit and/or stormwater management permit. Grading and erosion control review can occur in the context of the stormwater management review and permitting process. The ordinance references the City’s Land Disturbance Guidance document (Appendix D), which defines the technical erosion control, sediment control, and stormwater management guidelines required to be met. 6.7.

City of Mendota Heights Implementation Priorities Table 6.1 lists the implementation priorities for the City of Mendota Heights. A tentative timetable is included with the table. Many of the City’s priorities revolve around improvements to existing stormwater infrastructure. 6.9. NPDES Permit In 2003, the MPCA required the City to submit an NPDES Permit Application to minimize the discharge of stormwater runoff pollutants and authorize stormwater discharge from the City’s MS4. The City will use funds generated from its SWU as the primary funding mechanism for its SECTION 6 Surface Water Management Plan Section 6 City of Mendota Heights WSB Project No. 1735-04 Page-11 implementation program including; maintenance, repairs, capital projects, studies, etc. It is anticipated that the SWU will generate approximately $400,000 per year. If funds from this utility fee do not cover necessary costs, the City will consider adjusting the SWU fee to cover the costs associated with the implementation program. The City will continue to review the stormwater utility fee annually and adjust based on the stormwater related needs of the City and other available funding mechanisms. The City will also take advantage of grant or loan programs to offset project costs where appropriate and cost-effective. 6.10. Plan Revision and Amendments The City may need to revise this SWMP to keep it current. Any significant amendments that are made to the plan must be submitted to the LMRWD and LMRWMO for review and approval before adoption by the City. The City anticipates updating the Implementation Plan annually. These changes will be submitted to the Watershed Commissions for their record but not for review and approval. The City may amend this plan at any time in response to a petition by a resident or business. Written petitions for plan amendments must be submitted to the City Administrator. The petition must state the reason for the requested amendment, and provide supporting information for the City to consider the request. The City may reject the petition, delay action on the petition until the next full plan revision, or accept the petition as an urgent issue that requires immediate amendment of the plan. The City of Mendota Heights may also revise/amend the plan in response to City-identified needs. This SWMP is intended to be in effect for 10 years (implementation program outlines cost/activities for seven years) per state statute. The SWMP will be revised/updated at that time, to the extent necessary. 6(&7,21&RPPHQWV$QQXDO2

Objectives: The objectives prevent the introduction of pollutants to the stormwater system by any user, to prohibit illicit connections and discharges to the stormwater system, and to establish authority to carry out all inspection, surveillance and monitoring procedures necessary to ensure compliance with this chapter. B. Discharge Prohibitions: 1. Prohibition Of Illegal Disposal And Dumping Of Substances And Materials: No person shall throw, deposit, place, leave, maintain, or store any substance upon any street, alley, sidewalk, storm drain, inlet, catch basin conduit or drainage structure, business place or upon any public or private plot of land, so that the same might be or become a pollutant, except if secured within a container or bag or contained within a lawfully established waste disposal facility. No person shall intentionally dispose of grass, leaves, dirt or landscape material into a water resource, buffer, street, road, alley, catch basin, culvert, curb, gutter, inlet, ditch, natural watercourse, flood control channel, canal, storm drain or any fabricated natural channel. 2. Prohibition Of Illicit Discharges: No person shall discharge or cause to be discharged into the stormwater system or watercourses any materials, including, but not limited to, pollutants or waters containing any pollutants that cause or contribute to a violation of applicable water quality standards, other than stormwater. a. The commencement, execution or continuance of discharge of pollutants to the stormwater system is prohibited except as follows: water line flushing or other potable water sources, landscape irrigation or lawn watering, diverted stream flows, groundwater infiltration to storm drains, uncontaminated pumped groundwater, foundation or footing drains (not including active groundwater dewatering systems), crawl space pumps, air conditioning condensation, springs, noncommercial washing of vehicles, natural riparian habitat or wetland flows, firefighting activities, and any other water source not containing pollutants. b. Discharges specified in writing by the authorized enforcement agency as being necessary to protect public health and safety are allowed. c. Dye testing is an allowable discharge, but requires a verbal notification to the authorized enforcement agency prior to the time of the test. d. The prohibition shall not apply to any nonstormwater discharge permitted under an NPDES permit, waiver, or waste discharge order issued to the discharger and administered under the authority of the federal environmental protection agency, Minnesota pollution control agency, or other agency, provided that the discharger is in full compliance with all requirements of the permit, waiver, or order and other applicable laws and regulations, and provided that written approval has been granted for any discharge to the stormwater system. 3. Prohibition Of Illicit Connections: The construction, use, maintenance, or continued existence of such connections that intentionally convey nonstormwater to the stormwater system is prohibited. This prohibition expressly includes, without limitation, illicit connections made in the past, regardless of whether the connection was permissible under law or practices applicable or prevailing at the time of connection. A person is considered to be in violation of this chapter if the person connects a line conveying wastewater to the stormwater system, or allows such a connection to continue. No person shall connect or convey water from floor drains to the storm sewer system. C. Discharge Prevention: 1. Discharge Prevention Requirements: Any property owner within the city shall comply with the following requirements to prevent discharges: a. No person shall leave, deposit, discharge, dump, or otherwise expose any chemical or septic waste in an area where discharge to a street, storm sewer system, or surface water body may occur. This prohibition shall apply to actual discharges as well as the potential for discharge from, for example, a septic system in a location where emergency overflow could discharge to a street, surface water body, or storm sewer system. b. Individual sewage treatment systems must be maintained in order to prevent failure. No part of any individual sewage treatment system requiring on land or inground disposal of waste shall be located in an area where effluent could immediately or gradually reach a body of water due to the existing physical characteristics of the site or the system. c. Recreational vehicle sewage shall be disposed of at a proper sanitary waste facility. Waste must not be discharged in an area where drainage to streets or storm sewer system may occur. d. Water in swimming pools must sit for seven (7) days without the addition of any chlorine to allow for evaporation of the chlorine before it is discharged. e. Runoff of water from residential properties shall be minimized to the maximum extent practicable. Paved areas must be swept prior to wash down activity. Runoff water from the washing down of paved areas on commercial or industrial properties is prohibited unless necessary for health or safety purposes and is not in violation of any other applicable regulations. f. Mobile washing companies, such as carpet cleaning and mobile vehicle washing services, shall dispose of any wastewater to the sanitary sewer system. Wastewater shall not be discharged to the streets or storm sewer system. g. Objects such as motor vehicle parts that contain grease, oil or other hazardous substances and unsealed receptacles containing hazardous materials shall not be stored in areas susceptible to runoff. Any machinery or equipment that is to be repaired or maintained in areas susceptible to runoff shall be placed in a confined area to contain any leaks, spills, or discharges. h. Debris and residue shall be removed, as required below: (1) All motor vehicle parking lots and private streets shall be swept, at a minimum of once a year in the spring, to remove debris. Such debris shall be collected and disposed of properly. (2) Fuel and chemical residue or other types of potentially harmful material, such as animal waste, garbage or batteries shall be removed as soon as possible and disposed of properly. Household hazardous waste must be disposed of through the county collection program or at any other authorized disposal site. Household hazardous waste shall not be placed in a trash container. D. Industrial Activity Discharges To The Storm Sewer System: 1. Any person subject to an industrial activity NPDES stormwater discharge permit shall comply with all provisions of such permit. Proof of compliance with said permit may be required in a form acceptable to the city prior to allowing of discharge to the storm sewer system. 2. All facilities that have stormwater discharges associated with industrial activity must adhere to the following requirements: Any person responsible for a property or premises, which is, or may be, the source of an illicit discharge may be required to implement, at said person's expense, additional structural and nonstructural BMPs to prevent the further discharge of pollutants to the storm sewer system. These BMPs shall be part of a stormwater pollution prevention plan (SWPPP) as necessary for compliance with requirements of the NPDES permit. E. Suspension Of Stormwater System Access: 1. Suspension Due To Illicit Discharges In Emergency Situations: The city may, without prior notice, suspend stormwater system discharge access to a person when such suspension is necessary to stop an actual or threatened discharge which presents or may present imminent or substantial danger to the environment, or to the health or welfare of persons, or to the stormwater system or waters of the United States. If the violator fails to comply with a suspension order issued in an emergency, the authorized enforcement agency may take such steps as deemed necessary to prevent or minimize damage to the stormwater system or waters of the United States, or to minimize danger to persons. If authorized enforcement agency takes steps to prevent or minimize damage to the stormwater system or waters of the United States, or to minimize danger to persons, the city may bill the property owner and/or operator, or lien the subject property for the cost of the action. 2. Suspension Due To The Detection Of Illicit Discharge: Any person discharging to the stormwater system in violation of this chapter may have their stormwater system access terminated if such termination would abate or reduce an illicit discharge. The city will notify a violator of the proposed termination of the violator's stormwater system access. The violator may petition the city for a reconsideration and hearing. A person is committing an offense and is subject to misdemeanor enforcement if the person reinstates stormwater system access to premises terminated pursuant to this chapter without the prior approval of the city. F. Monitoring Of Discharges: 1. The city shall be allowed to enter and inspect facilities and properties subject to regulation under this chapter as often as may be necessary to determine compliance with this chapter and for the purposes of inspection, sampling, examination, and the performance of any additional duties as defined by state and federal law that relate to the discharge of stormwater. If a person does not wish to allow the city to enter a building to conduct the required activity, he or she may retain a private inspector to conduct the activity. The private inspector must have credentials that are acceptable to the city. The private inspector shall provide the city with the relevant samples, test results, reports or any other information that is being requested. 2. The city shall have the right to establish on any permitted facility such devices as are necessary in the opinion of the authorized enforcement agency solely to conduct monitoring and/or sampling of the facility's stormwater discharge. 3. The city has the right to require the discharger to install monitoring equipment to ensure discharge is in compliance with MPCA standards. The facility's sampling and monitoring equipment shall be maintained at all times in a safe and proper operating condition by the discharger at its own expense. 4. Any temporary or permanent obstruction to safe and easy access to the facility to be inspected and/or sampled shall be promptly removed by the owner or operator at the written or oral request of the city and shall not be replaced. The costs of clearing such access shall be borne by the owner or operator. 5. Unreasonable delays in allowing the city access to a permitted facility is a violation of a stormwater discharge permit and of this chapter. A person who is the owner and/or operator of a facility with an NPDES permit to discharge stormwater associated with industrial activity commits an offense if the person denies the city reasonable access to the permitted facility for the purpose of conducting any activity authorized or required by this chapter. G. Requirement To Prevent, Reduce, And Control Stormwater Pollutants By The Use Of Best Management Practices: 1. Owner Responsibility: The owner or operator of any property shall provide, at owner/operator's expense, reasonable protection from accidental discharge of prohibited materials or other wastes into the municipal stormwater system or watercourses through the use of structural and nonstructural best management practices (BMPs). Further any person responsible for a property or premises, which is, or may be, the source of an illicit discharge, may be required to implement, at said person's expense, additional structural and nonstructural BMPs to prevent the further discharge of pollutants to the stormwater system. These BMPs are listed in the stormwater pollution prevention plan (SWPPP) and the Minnesota pollution control agency's current BMPs, and are necessary for compliance with requirements of the NPDES permit and chapter 6 of the city's surface water management plan (SWMP). H. Watercourse Protection: 1. Owner Responsibility: Every owner of a property through which a watercourse passes, or such person's lessee, shall keep and maintain that part of the watercourse within their property free of trash, debris, excessive vegetation, and other obstacles that would pollute, contaminate, or significantly impact the flow of water through the watercourse. All owners or lessees shall maintain existing privately owned structures within or adjacent to a watercourse, so that such structures will not become a hazard to the use, function, or physical integrity of the watercourse. I. Notification Of Spills: 1. Notwithstanding other requirements of law, as soon as any person responsible for a facility, vehicle or operation, or responsible for emergency response for a facility or operation has knowledge of any known or suspected release of materials of any amount which are resulting or may result in illicit discharges or pollutants discharging into the stormwater system, watercourse, or waters of the United States, said person shall take all necessary steps to ensure the discovery, containment, and cleanup of such release. In the event of such a release of hazardous materials said person shall immediately notify the city and other emergency response agencies of the occurrence via emergency dispatch services. In the event of a release of nonhazardous materials, said person shall notify the city in person or by phone no later than the beginning of the next business day. If the discharge of prohibited materials emanates from a commercial or industrial establishment or vehicle, the owner or operator of such establishment or vehicle shall also retain a written record of the discharge and the actions taken to prevent its recurrence. Such records shall be retained for at least ten (10) years, or longer if required by other regulatory authority.

The techniques utilized for temporary or permanent stabilization fail within one year of installation or before the final plan is implemented for the site or portion of the site, whichever comes later. 4. The city determines that its actions are necessary to prevent excessive erosion from occurring on the site, or to prevent nuisance conditions from occurring on adjacent or nearby properties. The city shall use funds recovered from the security to reimburse the city for all direct and indirect costs incurred in doing the remedial work undertaken by the city or private contractor under contract with the city. (Ord. 421, 2-3-2009)  11-6-8: POSTCONSTRUCTION STORMWATER RUNOFF: A. Objectives: The objectives of this section are to establish minimum stormwater management requirements and controls to protect and safeguard the general health, safety, and welfare of the public residing in watersheds within this jurisdiction. This section seeks to meet that purpose through the following objectives: 1. Reduce stormwater runoff rates and volumes, soil erosion and nonpoint source pollution, wherever possible, through stormwater management controls and to ensure that these management controls are properly maintained and pose no threat to public safety; 2. Control stormwater runoff from development and redevelopment to reduce flooding, silt deposits and stream bank erosion, and maintain the integrity of stream channels; 3. Control nonpoint source pollution caused by stormwater runoff from development; and 4. Control the total annual volume of surface water runoff which flows from any specific site following development. B. Applicability: The rules of applicability are as set forth in section 11-6-6, "Construction Site Stormwater Runoff And Erosion Control", of this chapter. C. Stormwater Pollution Prevention Plan: 1. Stormwater Pollution Prevention Plan Required For All New Developments And Redevelopments: No application for development or redevelopment will be approved unless it includes a stormwater pollution prevention plan detailing how runoff and associated water quality impacts resulting from the development will be controlled or managed and contains the submission materials identified in subsection 11-6-6D of this chapter. This plan must indicate whether stormwater will be managed on site or off site and, if on site, the general location and type of practices. The stormwater pollution prevention plan(s) shall be referred for comment to interested agencies, and any comments must be addressed in a final stormwater pollution prevention plan. This final plan must be signed by a licensed professional engineer (PE) of the state of Minnesota. 2. Design Of Stormwater Facilities: The stormwater pollution prevention plan shall meet the design requirements outlined in the city's land disturbance guidance document. 3. Maintenance Of Existing Stormwater Facilities: Any stormwater facility in existence prior to the adoption date hereof shall be maintained by the owner of the stormwater facility and in a manner to conform to design standards for that facility. Any redevelopment of the stormwater facility shall require that the facility meet current stormwater design standards as set forth in the city's land disturbance guidance document. The thresholds for maintenance are triggered once sediment deposits reach a point greater than is allowed under the design standard criteria, or such deposits begin to have a substantial effect on the water quality or holding capacity of the pond. 4. Inspection Of Stormwater Facilities: Inspection programs shall be established on a regular basis, including, but not limited to, an inspection in accordance with the schedule defined in the MPCA MS4 permit section V, part 6.b or more often if deemed necessary to ensure proper functioning of the stormwater management facility. Inspections are the responsibility of the owner of the stormwater facility and must be completed by a certified erosion control specialist in the state of Minnesota hired for that purpose. Inspection results must be completed and submitted to the city in accordance with the schedule defined in the MPCA MS4 permit section V, part 6.b from the completion of development or from the adoption date hereof for a preexisting stormwater facility. Inspections may include, but are not limited to: reviewing maintenance and repair records; sampling discharges, surface water, groundwater, and material or water in drainage control facilities; and evaluating the condition of drainage control facilities and other stormwater treatment practices. All new and existing stormwater management facilities must undergo, at a minimum, an inspection in accordance with the schedule defined in the MPCA MS4 permit section V, part 6.b to document maintenance and repair needs and ensure compliance with the requirements of this chapter and accomplishment of its purposes. This maintenance may include: removal of silt, litter and other debris from all catch basins, inlets and drainage pipes; grass cutting and vegetation removal; and necessary replacement of landscape vegetation. Any maintenance needs found must be addressed in a timely manner, as determined by the city. The inspection and maintenance requirement may be increased as deemed necessary to ensure proper functioning of the stormwater management facility. D. Maintenance Covenants: Maintenance of all stormwater management facilities shall be ensured through the creation of a formal maintenance covenant that must be approved by the city and recorded at the Dakota County recorder's office prior to final plan approval. As part of the covenant, a schedule shall be developed for when and how often maintenance will occur to ensure proper function of the stormwater management facility. The covenant shall also include plans for periodic inspections to ensure proper performance of the facility between scheduled cleanouts. The owner/operator shall show in the maintenance covenant how it will utilize best management practices (BMPs) to prevent discharge of pollutants into the stormwater system. These BMPs are listed in the city's stormwater pollution prevention plan (SWPPP) and the most current Minnesota pollution control agency BMP standards, the state of Minnesota stormwater manual and are necessary for compliance with requirements of the NPDES permit and the city's local surface water management plan. The threshold for maintenance is triggered once sediment deposition reaches a point greater than is allowed under the design standard criteria, or such deposition begins to have a substantial effect on the water quality or holding capacity of the pond. E. Right Of Entry For Inspection: When any new drainage control facility is installed on private property, or when any new connection is made between private property and a public stormwater system, the property owner shall grant to the city the right to enter the property at reasonable times and in a reasonable manner for the purpose of inspection. This includes the right to enter a property when the city has a reasonable basis to believe that a violation of this chapter is occurring or has occurred, and to enter when necessary for abatement of a public nuisance or correction of an ordinance violation. F. Records Of Installation And Maintenance Activities: Parties responsible for the operation and maintenance of a stormwater management facility shall make records of the installation, inspections, and of all maintenance and repairs, and shall retain the records for at least ten (10) years.

CONVEYANCE AND STORAGE SYSTEM CONCEPTS 1.1. Storm Sewer and Channels In the Mendota Heights SWMP stormwater model, a combination of storm sewer and channels has been used to transport simulated stormwater runoff. A complete system consists of a complex web of trunks, manholes, lateral lines, overland drainage ways, catch basin leads, catch basins, pond inlets and outlets, and many other items. Proper design of a storm sewer system requires that all sewer lines be provided with access through manholes for maintenance and repair operations. Generally, spacing of manholes should be no greater than 400 feet. Intervals on larger diameter lines can be increased when the pipes are sufficiently large for a person to physically enter the storm sewer pipe for maintenance operations. Regardless of sewer size, manholes should normally be provided at all junction points and at points of abrupt alignment or grade changes. Although lateral systems are designed for the 10-year storm event, their performance must be analyzed for storms exceeding the design storm. Lateral and trunk pipes will surcharge when the design storm is exceeded. During surcharging, the pipes operate as closed conduits and become pressurized with different pressure heads throughout the system. Low areas that are commonly provided with catch basins become small detention ponds often performing like pressure relief valves with water gushing out of some locations. For this reason, it is extremely important to ensure that these low areas have an acceptable overland drainage route with proper transfer capacity. At a minimum, ponding on streets must meet all of the requirements of the 100-year design criteria. For safety reasons, the maximum depth should not exceed two feet at the deepest point and the lowest ground at adjacent building elevation should be at least one and a half feet above the elevation to which water could rise before overflowing through adjacent overland routes. All storm sewer facilities, especially those conveying large quantities of water at high velocities, should be designed with efficient hydraulic characteristics. Manholes and other structures at points of transition should be designed and constructed to provide gradual changes in alignment and grade. Pond outlet control structures should be designed to allow water movement in natural flow line patterns, to minimize turbulence, to provide good self-cleaning characteristics, and to prevent damage from erosion. Intake structures should be liberally provided at all low points where stormwater collects and at points where overland flow is to be intercepted. Inlet structures are of special importance, since it is a poor investment to have an expensive storm sewer line flowing partially full while property is being flooded due to inadequate inlet capacity. Intake grates and opening should be self-cleaning and designed to minimize capacity reduction when clogged with twigs, leaves, and other debris. Effective energy dissipation devices or stilling basins to prevent stream bank or channel erosion at all stormwater outfalls should be provided. The following recommendations should be kept in mind when designing an outlet: Inlet and outlet pipes of stormwater ponds should be extended to the pond NWL whenever possible. Outfalls with velocities of less than four feet per second (fps) that project flows downstream into the channel in a direction 30 degrees or less from the normal channel axis generally do not require energy dissipaters or stilling basins, but do require riprap protection. Where an energy dissipater is used, it should be sized to provide an average outlet velocity of less than four fps, unless riprap is also used. In the latter case, or when discharge occurs at NWL of a pond, the average outlet velocity should not exceed six fps. Where outlet velocities exceed six fps, the design should be based on the unique site conditions present. Submergence of the outlet or installation of a stilling basin approved by the City is required when excessive outlet velocities are experienced. In the case of discharge to channels, riprap should be provided on all outlets to an adequate depth below the channel grade and to a height above the outfall or channel bottom. It should be placed over a suitably graded filter material and filter fabric to ensure that soil particles do not migrate through the riprap and reduce its stability. Riprap should be placed to a thickness at least two and a half times the mean rock diameter so as to ensure that it will not be undermined or rendered ineffective by displacement. If riprap is used as protection for overland drainage routes, grouting may be recommended. Overland drainage routes where velocities exceed six fps should be reviewed by the City Engineer and approved only when suitable stabilization measures are proposed. Open channels and swales are recommended where flows and small grade differences prohibit the economical construction of an underground conduit and in areas where open channel type drainage will enhance the aesthetic qualities of a development. Whenever possible, a minimum slope of two percent should be maintained in unlined open channels and overland drainage routes. Slopes less than two percent and greater than one percent are difficult to construct and maintain and may require an underdrain system. Slopes less than one percent should not be allowed. Side slopes should be a maximum of 4:1 (horizontal to vertical) with gentler slopes being desirable. Where space permits, slopes should be cut back to match existing grade. In general, the flatter the channel side slopes and the more meandering the channel alignment the more natural the channel will appear. Natural looking channels use significantly more space than common ditches. One method of providing this space is to incorporate greenway corridors over the channel area. Rock riprap should be provided at all points of juncture between two open channels and where storm sewer pipes discharge into a channel. The design velocity of an open channel should be sufficiently low to prevent erosion of the bottom. Riprap or concrete liners should be provided in areas where high velocities cannot be avoided. Periodic cleaning of an open channel is required to ensure that the design capacity is maintained. Therefore, all channels should be designed to allow easy access for equipment. Sanitary sewer manholes that could be subject to temporary inundation, due to their proximity to ponds, channels, or roadway low points, should be equipped with watertight castings. Precautions should be taken during construction to prevent the entrance of stormwater into the sanitary sewer. When access is required at all times, sanitary manholes located near ponding areas should be raised above the 100-year HWL. If access is not required, water tight castings should be installed. Future storm drainage construction should include provisions for improving the water tightness of nearby sanitary sewer manholes. All newly constructed sanitary manholes in the vicinity of ponding areas and open channels described in this report should be waterproof. 1.2. Ponds Stormwater ponding areas are an essential part of any storm drainage system. These areas provide locations where stormwater flows can be reduced to provide flood protection for downstream areas. The effective use of ponding areas enables the installation of outflow storm sewers and channels with reduced capacities, since the duration of the design storm is effectively increased over the total time required to fill and empty ponds. Smaller capacity trunk storm sewer and channels provide a cost savings to the City. The use of ponds to control stormwater runoff rates is a recent phenomenon. Historically, older cities have piped stormwater directly to the nearest large receiving water or river. Continued use of this practice has both cost and regulatory implications. In terms of cost, few cities have the funds necessary to build pipes that provide 100-year protection to properties. In fact, the older cities that have historically piped all their stormwater find that the systems they constructed provide nowhere near the 100-year protection found in newer cities that have used ponds. In terms of the regulatory control, many direct discharges (without ponding) to waters of the state are precluded. At present, even direct discharges to wetlands that are not considered waters of the state are regulated through the NPDES construction permit. Cost and regulatory considerations aside, well designed ponds: 1. Improve water quality 2. Recharge the groundwater table 3. Provide aesthetic, recreational and wildlife benefits Ponds improve stormwater quality by allowing nutrients and sediments carried by runoff to settle before discharge to important receiving waters. Groundwater recharge is increased by restricting the outflow rate from a pond, thus allowing more water to infiltrate into the soil. Careful planning of ponds can enhance a development’s appeal and still provide efficient stormwater management. In fact, lots with pond frontage command a higher price than lots without. To provide proper protection for adjacent property, the design storm for ponding areas is the maximum flood elevation obtained from analyzing 100-year critical events of different duration. Regardless the duration of the critical event, a Type II, 24-hour, 100-year rainfall event must also be analyzed. The lowest exposed elevations of structures that are adjacent to ponds should be certified by the builder during basement construction to ensure adequate freeboard. Runoff determinations for pond design vary from those for storm sewer calculations. The critical storm for storm sewer design is the short, high intensity storm, whereas the critical storm for pond design is often of longer duration, since water is being stored for longer periods of time and released at a slower rate. The use of HydroCAD computer modeling in the analysis of the ponding system has allowed for the efficient review of complicated routing patterns, each comprised of several ponds. The pond storage and outflow rates, adjusted by lag time, were determined by the HydroCAD program for all the ponds identified in this Plan. The lag time is significant as it represents the attenuation of peak flows at each pond and generally shows that the peaks are not occurring at the same time. This implies that the direct runoff to a pond has generally passed through to the downstream trunk system before the inflow of large volumes of runoff from upstream ponds. 2. WATER QUALITY SYSTEM CONCEPTS The only effective way to maintain high quality water bodies is to prevent sediment, nutrients and other materials from entering the storm drainage system. Complete interception of stormwater for treatment at the point of discharge is not currently feasible, though the City encourages the implementation of techniques such as rainwater gardens, infiltration areas, and filtration swales that capture a portion of runoff at the point of generation. Application of these small-scale techniques should be on a site specific basis. 2.1. Pollutant Control The three main sources for degradation of water quality are: 1. Solids and associated chemicals (including calcium chloride and salt) from erosion and street sanding, 2. Composted decay around ponds, and 3. Fertilizers and other chemicals from farming practices, impervious surfaces, or lawn care. Identification of the source and implementation of reasonable control measures can minimize the degradation of Mendota Heights’ waterbodies. In areas where development is taking place, stormwater runoff frequently contains substantial quantities of solids. Most commonly, these sediments are carried by runoff into the storm sewer from large grading sites, though fully developed areas also generate sediment loads particularly from winter sanding operations and in areas of structurally failing pipes. For developing areas, strict on-site erosion control practices are required to prevent sediments from entering downstream water bodies. Inspections should be conducted by the City to verify that the erosion control practices have been installed and maintained properly. Even with extensive erosion control practices, sediment and airborne particulates will continue to enter surface waters of the City. The importance of erosion control measures during construction cannot be overemphasized. The BMPs recommended in the MPCA Protecting Water Quality in Urban Areas should be followed for all developments. The Minnesota general NPDES stormwater permit for construction activity requires a permit for construction activities that disturb one or more acres. When disturbing 10 or more acres, developers are required to provide temporary settling ponds to treat the runoff from their grading sites. These ponds are intended to prevent the introduction of sediment and its associated pollution into the storm sewer system and are required to function, in their various forms, until grading has ceased and adequate cover has been established. At a minimum, these temporary sedimentation basins should meet the requirements set forth in the NPDES general permit for construction activities. When the outlet for a siltation basin, either permanent or temporary, is located below the normal water surface, the basin can also serve to confine floating solids that may otherwise enter a downstream pond or lake. This practice is typically referred to as skimming. If a hazardous material such as fuel oil were to spill, a skimmer structure would retain it within the basin and thus isolate it for easy access and prompt cleanup. Skimmer structures should be used for all constructed ponds upstream of wetlands, lakes, rivers and streams. For constructed ponds that discharge into other constructed ponds, skimmer structures are not as important. Ideally, some sort of solids removal system should be installed wherever a storm sewer outlets into a pond. In certain cases, settling chamber (sump) type catch basins or manholes can be provided for storm sewers that discharge into ponds. These can provide effective removal of sand and gravel, which may be flushed into the storm sewer from streets and highways, but are ineffective in the removal of finer particles such as silts and clays. Use of this type of catch basin or manhole should be limited to those areas where regular maintenance is practical and to where the sump can be realistically expected to intercept sand from winter sanding operations and gravel from driveways and construction sites. Of late a concern regarding West Nile virus and mosquito breeding habitat has called into question the use of sump manholes. The latest data suggests that many different breeding environments exist for the mosquitoes that carry the virus including ponds, wetlands, catch basins, and manholes. Obviously, eliminating these elements of the system is not feasible. Though they should be used sparingly, sump manholes should not be prohibited due to a concern over West Nile virus. It bears repetition that a solids removal structure must be regularly maintained if it is to remain effective. Since maintenance is the controlling factor in the long term performance of sediment control measures, ponds are recommended over sump manholes. Sump manholes, if numerous, often go without maintenance. An individual pond requires more maintenance time than a sump, but system maintenance time goes down when ponds are the preferred method of sediment removal as long as pond slopes and benching allow access by maintenance equipment. For this reason sump manholes should be limited to storm sewer lines discharging directly to wetlands, lakes, rivers, streams, ravines, and constructed channels and should be avoided upstream of constructed ponds. In all cases, the location, type, and number of sediment control structures must be established at the time of final design of that portion of the storm sewer system. Maintenance of the system is discussed further in Section 6. Even with the best and most expensive solids removal system, contamination of ponds and lakes will occur unless particular attention is paid to those activities that occur after development of a site. Developers must utilize the BMPs to minimize erosion during the mass grading phase of construction. But property owners must also use care in the development and maintenance of their lawns and open areas. Debris is frequently raked from lawns into gutters; from there, if it is not removed, it washes into the storm sewer system. Generally speaking, water quality ponding within a development has to treat storm water to the level required by the downstream receiving water body and its attendant management strategy. This SWMP calls for detention pond design according to the design program developed by William Walker. At a minimum, though, detention ponds should contain wet volume equivalent to the runoff from a 2.5-inch rainfall over their tributary area. Occasionally, with small plats (of five acres of less), water quality ponding cannot be constructed to the extent required by the SWMP without severely hampering the site development or destroying other habitat such as upland grasslands and forests. In such cases, it is within the City’s discretion to reduce the required water quality ponding and/or require other methods such as filtration swales or filter beds.

The requirements below are meant to serve as a general guideline and do not account for all possible site conditions or situations. Additional measures may be necessary to meet the intent of the Mendota Heights city code. It is the obligation of the owner and designer to consider all factors contributing to erosion, flooding, and water quality impairments on the project site and include appropriate Best Management Practices for minimizing erosion and providing permanent stormwater runoff management. 1.0 Construction Site Stormwater Runoff Control 1.1 Erosion Control and Prevention Practices a.The Permittee must plan for and implement appropriate construction phasing vegetative buffer strips, horizontal slope grading, and other construction practices to minimize erosion. All areas not to be disturbed shall be marked (e.g. with flags, stakes, signs, silt fence etc.) on the project site before any work begins. The Permittee must minimize the need for disturbance of portions of the project that have steep slopes. For those sloped areas which must be disturbed, the Permittee must use techniques such as phasing and stabilization practices designed for steep slopes (e.g., slope draining and terracing). b.All exposed soil areas (including stockpiles) must be stabilized as soon as possible to limit soil erosion but in no case later than 14 days after the construction activity in that portion of the site has temporarily or permanently ceased. For Public Waters that the Minnesota Department of Natural Resources has promulgated “work in water restrictions” during specified fish spawning time frames, all soil areas that are within 200 feet of the water’s edge, and drain to these waters must complete the stabilization activities within 24 hours during the restriction period. c.Additional BMPs together with enhanced runoff controls are required for discharges to special waters and impaired waters. The BMPs identified for each special or impaired water are required for those areas of the project draining to a discharge point on the project that is within one mile of a special or impaired water and flows to that water. d.The normal wetted perimeter of a temporary or permanent drainage ditch that drains water for the project site or diverts water around the project must be stabilized 200 lineal feet from the property edge or from a discharge point to a surface water. Stabilization must occur within 24 hours of connection to surface waters. Applying mulch, hydromulch, tackifier, polyacrylamide or similar erosion prevention practices is not acceptable stabilization in any part of a temporary or permanent drainage ditch or swale. e.Pipe outlet must have temporary or permanent energy dissipation within 24 hours before connecting to surface water. f.When possible, all slopes must be graded in such a fashion so that tracking marks made from heavy equipment are perpendicular to the slope. g.All areas disturbed during construction must be restored as detailed in these requirements. The type of permanent restoration shall be clearly shown on the plans including but not limited to sod, seed, impervious cover and structures. A minimum of 6 inches of topsoil must be installed prior to permanent restoration. Areas in which the top soil has been placed and finish graded or areas that have been disturbed and other grading or site building construction operations are not actively underway must be temporary or permanently restored as set forth in the following requirements: i)Areas with slopes that area less than 3:1 must be seeded and mulched within 14 days of the area not being actively worked. ii)Areas with slopes that area greater or equal to 3:1 must be seeded and erosion control blanket placed within 14 days of the area not being actively worked. iii)All seeded area must be either mulched and disc anchored, hydro- mulched, or covered by erosion control blanket to reduced erosion and protect the seed. Temporary or permanent mulch must be disc anchored and applied at a uniform rate LAND DISTURBANCE GUIDANCE DOCUMENT City of Mendota Heights, MN WSB Project No. 1734-04 Page 2 of 2 tons per acre and have 90% coverage. iv)If the disturbed area will be re-disturbed within a six month period, temporary vegetative cover shall be required consisting of an approved seed mixture and application rate. v)If the disturbed area will not be re-disturbed within a six month period, permanent vegetative cover shall be required consisting of an approved seed mixture and application rate. vi)All areas that will not have maintenance done such as mowing as part of the final design shall be permanently restored using an approved seed mixture and application rate. vii)Restoration of disturbed wetland areas shall be accomplished using an approved seed mixture and application rate. h.All erosion control measures must be maintained for the duration of the project until final stabilization has been achieved in accordance with Section 1.7. If construction operations or natural events damage or interfere with any erosion control measures, they shall be restored to serve their intended function. i.Additional erosion control measures shall be added as necessary to effectively protect the natural resources of the City. The temporary and permanent erosion control plans shall be revised as needed based on current site conditions and to comply with all applicable requirements. 1.2 Sediment Control Practices a.Sediment control practices must be established on all down gradient perimeters before any upgradient land disturbing activities begin. These practices must remain in place until final stabilization has been achieved in accordance with Section 1.7. b.If down gradient treatment system is overloaded additional up gradient sediment control practices must be installed to eliminate overloading. The SWPPP must be amended to identify the additional practices. c.There shall be no unbroken slope length greater than 75 feet with a grade of 3:1 or steeper. d.All storm drain inlets must be protected by approved BMPs during construction until all potential sources for discharge have been stabilized. These devices must be maintained until final stabilization is achieved. Inlet protection may be removed if a specific safety concern (street flooding/freezing) has been identified. e.Temporary stockpiles must have silt fence or other effective sediment controls on the down gradient side of the stockpile and shall not be placed at least twenty five (25) feet from any road, wetland, protected water, drainage channel, or storm water inlets. Stockpile left for more than fourteen (14) days must be stabilized with mulch, vegetation, tarps or other approved means. f.A 50-ft natural buffer or (if a buffer is infeasible on the site) provide redundant sediment controls when a surface water is located within 50 feet of the project’s earth disturbances and stormwater flows to the surface water. Natural buffers are not required adjacent to road ditches, judicial ditches, county ditches, stormwater conveyance channels, storm drain inlets, and sediment basins. g.Vehicle tracking of sediment from project shall be minimized by approved BMPs. These shall be installed and maintained at the City approved entrances. Individual lots shall each be required to install and maintained entrances throughout the construction building until a paved driveway is install. h.Sediment that has washed or tracked from site by motor vehicles or equipment shall be cleaned from paved surfaces throughout the duration of construction. i.Silt fence or other approved sediment control devices must be installed in all areas as shown on the SWPPP. j.Silt fence or other approved sediment control devices shall be required along the entire curb line, except for approved opening where construction entrance will be installed or drainage flows away from curb. This device must be maintained until final stabilization is achieved. k.Ditch checks shall be required in ditch bottoms. Spacing for the check must be as LAND DISTURBANCE GUIDANCE DOCUMENT City of Mendota Heights, MN WSB Project No. 1734-04 Page 3 followed:[Height in feet (of the sediment device used)] X 100 / Slope Gradient l.Dust control measures, such as application of water must be performed periodically due to weather, construction activity, and/or as directed by the City. m.Flows from diversion channels or pipes (temporary or permanent) must be routed to sedimentation basins or appropriate energy dissipaters to prevent the transport of sediment to outflow or lateral conveyors and to prevent erosion and sediment buildup when runoff flows into the conveyors. n.A concrete washout shall be installed on projects that require the use of concrete. All liquid and solid wastes generated by concrete washout operations must be contained in a leak-proof containment facility or impermeable liner. A sign must be installed adjacent to each washout facility to inform operators to utilize the proper facilities. o.All sediment control measures shall be used and maintained for the duration of the project until final stabilization has been achieved accordance with Section 1.7. If construction operations or natural events damage or interfere with any erosion control measures, they must be restored to serve their intended function. p.Additional sediment control measures shall be added as necessary to effectively protect the natural resources of the City. The temporary and permanent erosion control plans shall be revised as needed based on current site conditions and to comply with all applicable requirements. q.Restrict clearing and grading within 20 feet of an existing wetland, lake, or stream boundary to provide for a protective buffer strip of natural vegetation. 1.3 Temporary Sediment Basins a.A temporary sediment basin (or permanent) shall be provided when 10 or more acres of disturbed soil drain to a common location prior to the runoff leaving the site or entering surface waters. The Permittee is also encouraged, but not required to install temporary sediment basins in areas with steep slope or highly erodible soils even if the area is less than 10 acres and it drains to one common area. The basins shall be designed and constructed according to the following requirements: i)The basins must provide storage below the outlet pipe for a calculated volume of runoff from a 2 year, 24 hour storm from each acre drained to the basin, except that in no case shall the basin provide less than 1800 cubic feet of storage below the outlet pipe from each acre drained to the basin. ii)Where no such calculation has been performed, a temporary (or permanent) sediment basin providing 3,600 cubic feet of storage below the outlet pipe per acre drained to the basin shall be provided where attainable until final stabilization of the site. iii)Temporary basin outlets will be designed to prevent short-circuiting and the discharge of floating debris. The basin must be designed with the ability to allow complete basin drawdown (e.g., perforated riser pipe wrapped with filter fabric and covered with crushed gravel, pumps or other means) for maintenance activities, and provide a stabilized emergency overflow to prevent failure of pond integrity. Energy dissipation must be provided for the basin outlet. iv)Temporary (or permanent) basins must be constructed and made operational concurrent with the start of soil disturbance that is up gradient of the area and contributes runoff to the pond. v)Where the temporary sediment basin is not attainable due to site limitations, equivalent sediment controls such as smaller sediment basins, and/or sediment traps, silt fences, vegetative buffer strips or any appropriate combination of measures are required for all down slope boundaries of the construction area and for those side slope boundaries deemed appropriate as dictated by individual site conditions. In determining whether installing a sediment basin is attainable, the Permittee must consider public safety and may consider factors such as site soils, slope, and available area on site. This determination must be documented in the SWPPP. LAND DISTURBANCE GUIDANCE DOCUMENT City of Mendota Heights, MN WSB Project No. 1734-04 Page 4 vi)The Permittee shall maintain the sedimentation basins and will remain functional until an acceptable vegetative cover is restored to the site, resulting in a pre- development level rate of erosion. The city will not issue building permits for lots containing sediment basins until they have been removed or relocated based on the projects restoration progress. vii)Basins designed to be used for permanent stormwater management shall be brought back to their original design contours as defined in Section 1.7. 1.4 Dewatering and Basin Draining a.If water cannot be discharged into a sedimentation basin before entering a surface water it must be treated with the appropriate BMPs, such that the discharge does not adversely affect the receiving water or downstream landowners. The Permittee must make sure discharge points are appropriately protected from erosion and scour. The discharge must be dispersed over riprap, sand bags, plastic sheeting or other acceptable energy dissipation measures. Adequate sediment control measures are required for discharging water that contains suspended soils. b.All water from dewatering or basin draining must discharge in a manner that does not cause nuisance conditions, erosion in receiving channels, on down slope properties, or inundation in wetlands causing significant adverse impact to wetlands. 1.5 Inspections and Maintenance a.The Permittee shall be responsible for inspecting and maintenance of the BMPs b.The Permittee must routinely inspect the construction project once every 7 days during active construction and within 24 hours of a rainfall event of 0.5 inches or greater in 24 hours. c.All inspections and maintenance conducted during construction must be recorded in writing and must be retained with the SWPPP. Records of each inspection and maintenance activity shall include i)Date and time of inspection. ii)Name of person(s) conducting the inspections. iii)Findings of inspections, including recommendations for corrective actions. iv)Corrective actions taken (including dates, times, and the party completing the maintenance activities). v)Date and amount of all rainfall events 0.5 inches or greater in 24 hours. vi)Documentation of changes made to SWPPP. d.Parts of the construction site that have achieved final stabilization, but work continues on other parts of the site, inspections of the stabilized areas can be reduced to once a month. If work has been suspended due to frozen ground conditions, the required inspections and maintenance must take place as soon as runoff occurs or prior to resuming construction, which ever happens first. e.All erosion and sediment BMPs shall be inspected to ensure integrity and effectiveness. All nonfunctional BMPs shall be repaired, replaced or supplemented with a functional BMP. The Permittee shall investigate and comply with the following inspection and maintenance requirements. f.All silt fences must be repaired, replaced, or supplemented when they become nonfunctional or the sediment reaches 1/3 of the height of the fence. These repairs shall be made within 24 hours of discovery, or as soon as field conditions allow access. g.Temporary and permanent sedimentation basins must be drained and the sediment removed when the depth of sediment collected in the basin reaches 1/2 the storage volume. Drainage and removal must be completed within 72 hours of discovery, or as soon as field conditions allow access. h.Surface waters, including drainage ditches and conveyance systems, must be inspected for evidence of sediment being deposited by erosion. The Permittee shall remove all deltas and sediment deposited in surface waters, including drainage ways, catch basins, and other drainage systems, and re-stabilize the areas where sediment removal results in exposed LAND DISTURBANCE GUIDANCE DOCUMENT City of Mendota Heights, MN WSB Project No. 1734-04 Page 5 soil. The removal and stabilization shall take place within 7 days of discovery unless precluded by legal, regulatory, or physical access constraints. The Permittee shall use all reasonable efforts to obtain access. If precluded, removal and stabilization shall take place within 7 calendar days of obtaining access. The Permittee is responsible for contacting all local, regional, state and federal authorities and receiving any applicable permits, prior to conducting any work. i.Construction site vehicle exit locations shall be inspected for evidence of off-site sediment tracking onto paved surfaces. Tracked sediment shall be removed from all off-site paved surfaces, within 24 hours of discovery, or if applicable, within a shorter time. j.The Permittee is responsible for the operation and maintenance of temporary and permanent water quality management BMPs, as well as all erosion prevention and sediment control BMPs, for the duration of the construction work at the site. The Permittee is responsible until another Permittee has assumed control over all areas of the site that have not been finally stabilized or the site has undergone final stabilization, and a NOT has been submitted to the MPCA. k.If sediment escapes the construction site, off-site accumulations of sediment shall be removed in a manner and at a frequency sufficient to minimize off-site impacts (e.g., fugitive sediment in streets could be washed into storm sewers by the next rain and/or pose a safety hazard to users of public streets). l. All infiltration areas shall be inspected to ensure that no sediment from ongoing construction activities is reaching the infiltration area and these areas are protected from compaction due to construction equipment driving across the infiltration area. 1.6 Pollution Management Measures/Construction Site Waste Control a.The Permittee must implement the following pollution prevention management measures on the site. i)Solid Waste- Collected sediment, asphalt and concrete millings, floating debris, paper, plastic, fabric, construction and demolition debris and other wastes must be disposed of properly and must comply with MPCA disposal requirements. ii)Hazardous Materials such as oil, gasoline, paint and any hazardous substances must be properly stored, including secondary containment, to prevent spills, leaks or other discharge. Restricted access to storage areas shall be provided to prevent vandalism. Storage and disposal of hazardous waste shall be in compliance with MPCA regulations. iii)External washing of trucks and other construction vehicles must be limited to a defined area of the site. Runoff shall be contained and waste properly disposed of. No engine degreasing is allowed on site. iv)The City of Mendota Heights prohibits discharges of any material other than storm water, and discharges from dewatering or basin draining activities. Prohibited discharges include but are not limited to vehicle and equipment washing, maintenance spills, wash water, and discharges of oil and other hazardous substances. 1.7 Final Stabilization a.The Permittee must ensure final stabilization of the project. Final stabilization can be achieved in one of the following ways. b.All soil disturbing activities at the site have been completed and all soils will be stabilized by a uniform perennial vegetative cover with a density of at least 70 percent over the entire pervious surface area, or other equivalent means necessary to prevent soil failure under erosive conditions and; i)All drainage ditches, constructed to drain water from the site after construction is complete, must be stabilized to preclude erosion; and ii)All temporary synthetic, and structural erosion prevention and sediment control BMPs (such as silt fence) must be removed as part of the site final stabilization; LAND DISTURBANCE GUIDANCE DOCUMENT City of Mendota Heights, MN WSB Project No. 1734-04 Page 6 and iii)The Permittee must clean out all sediment from conveyances and from temporary sedimentation basins that are to be used as permanent water quality management basins. Sediment must be stabilized to prevent it from washing back into the basin, conveyances or drainage ways discharging off-site or to surface waters. The cleanout of permanent basins must be sufficient to return the basin to design capacity. c.For residential construction only, final stabilization has been achieved when: i)Temporary erosion protection and down gradient perimeter control for individual lots has been completed and the residence has been transferred to the homeowner. ii)The Permittee must distribute the MPCA “homeowner factsheet” to the homeowner so the homeowner is informed for the need, and benefits, of final stabilization. 1.8 Training: Training is required for those that are responsible for preparation of the SWPPP, management of the construction site and inspections. a.The SWPPP must provide a chain of command showing who prepared the SWPPP, who is responsible for the management of the construction site and inspections. b.The training shall consist of a course developed by a local, state or federal agency, professional organization, water management organization, or soil and water conservation district and must contain information that is related to erosion prevention, sediment control, or permanent stormwater management and must relate to the work that you are responsible for managing. LAND DISTURBANCE GUIDANCE DOCUMENT City of Mendota Heights, MN WSB Project No. 1734-04 Page 7 2.0 Stormwater Management Design Standards 2.1 Storm Sewer a.Provide for overflow routes to drain low points along streets or lot lines to ensure a freeboard of 2’ from the lowest ground adjacent to building and the calculated 100-year storm HWL elevation. Design criteria verifying the adequacy of the overland drainage route capacity is required calculated 100-year storm HWL elevation. Design criteria verifying the adequacy of the overland drainage route capacity is required. b.The storm sewer alignment shall follow the sanitary sewer and watermain alignment where practical with a minimum of 10’ of separation. Storm sewer placed along the curb alignment shall be along the curb opposite the watermain to maintain the 10’ separation. c.Catch basins shall be located on the tangent section of the curb at a point 3’ from the point of curve. Mid-radius catch basins will not be allowed. Also, catch basins shall be designed to collect drainage on the upstream side of the intersection. d.The maximum spacing between manholes is 400’. e.Manhole steps will be aligned and over the downstream side of the manhole. Steps within manholes will be: i)1” +/- Horizontal Alignment ii)1” +/- Vertical Alignment per latest OSHA Standards f.Any connections to existing manholes or catch basins shall be core drilled or the opening cut out with a concrete saw. No jack hammering or breaking the structure with a maul is permitted. Also, all connections to an existing system will require a manhole for access. g.To the greatest extent possible, manholes shall be placed in paved surfaces outside of wheel paths, (3’ and 9’ off centerline) or other readily accessible areas. h.Minimum pipe size shall be 12” diameter. i.Aprons or flared end sections shall be placed at all locations where the storm sewer outlets a ponding area. All inlet/outlet flared end sections shall be furnished with hot dipped galvanized trash guards. All trash guard installations will be subject to approval by the City Engineer. The last three pipe joints from the flared end section shall be tied together. j.Riprap and filter blanket shall be placed at all outlet flared end sections. k.The placement of the riprap shall be by hand. The minimum class of riprap shall be MnDOT 3601.2, Class III. A design criterion justifying the size and amount of riprap is required. Geotextile material is not allowed for filter aggregate where ice action along the shore line may tear the geotextile. l.The invert elevations of the pond inlet flared end sections shall match the NWL of the pond. Submerged outlets will only be allowed at the discretion of the City Engineer. m.If the storm sewer is to be installed less than 10’ deep within private property, the easement shall be a minimum of 20’ wide with the pipe centered in the easement. If the storm sewer is 10’ deep or greater, then the easement shall be twice as wide as the depth or as required by the City. n.Junction manholes should be designed to limit the hydraulic head increase by matching hydraulic flow lines and by providing smooth transition angles. o.In the development of any subdivision or ponding area, the developer and/or property owner is responsible for the removal of all significant vegetation (trees, stumps, brush, debris, etc.) from any and all areas which would be inundated by the designated controlled Normal Water elevation (NWL) of any required ponding easement as well as the removal of all dead trees, vegetation, etc., to the High Water Level (HWL) of the pond. p.Outlet control structures from ponding areas are required as directed by the City. Location and appearance of outlet structures shall be subject to City approval and may require landscape screening. q.Sump manholes with 3-foot sumps shall be constructed as the last structure that is roadway accessible prior to discharge to any waterbody. r.Inlets should be placed and located to eliminate overland flow in excess of 1,000 feet on minor streets, or a combination of minor streets and swales, and 600 feet on collector LAND DISTURBANCE GUIDANCE DOCUMENT City of Mendota Heights, MN WSB Project No. 1734-04 Page 8 streets and arterials. Additionally, inlets should be located such that 3 cfs is the maximum flow at the inlet for the 10-year design storm. 2.2 Outlet and Inlet Pipes a.Inlet and outlet pipes of stormwater ponds should be extended to the pond normal water level whenever possible. b.Outfalls with velocities less than 4 feet per second (fps) that project flows downstream into the channel in a direction 30 degrees or less from the normal channel axis generally do not require energy dissipaters or stilling basins, but do require riprap protection. c.Where an energy dissipater is used, it should be sized to provide an average outlet velocity of less than 4 fps, unless rip rap is also used. In the latter case, or when discharge occurs at NWL of a pond, the average outlet velocity should not exceed 6 fps. d.Where outlet velocities exceed 6 fps, the design should be based on the unique site conditions present. Submergence of the outlet or installation of a stilling basin approved by the City is required when excessive outlet velocities are experienced. e.In the case of discharge to channels, rip rap should be provided on all outlets to an adequate depth below the channel grade and to a height above the outfall or channel bottom. It should be placed over a suitably graded filter material and filter fabric to ensure that soil particles do not migrate through the rip rap and reduce its stability. Rip rap should be placed to a thickness at least 2.5 times the mean rock diameter so as to ensure that it will not be undermined or rendered ineffective by displacement. If rip rap is used as protection for overland drainage routes, grouting may be recommended. 2.3 Channels and Overland Drainage a.Overland drainage routes where velocities exceed 6 fps should be reviewed by the City Engineer and approved only when suitable stabilization measures are proposed. b.Open channels and swales are recommended where flows and small grade differences prohibit the economical construction of an underground conduit. Open channels and swales can provide infiltration and filtration benefits not provided by pipe. c.Whenever possible, a minimum slope of 2% should be maintained in unlined open channels and overland drainage routes. Slopes less than 2% and greater than 1% are difficult to construct and maintain and may require an underdrain system. Slopes less than 1% are not allowed for lot drainage and channels designed primarily for conveyance. d.Minimum grade for lot drainage swales and lot grading shall be 2% or greater. e.Maximum length for drainage swales shall be 300 feet or a total of eight lots draining to a point, or as approved by the City Engineer. f.Channel side slopes should be a maximum of 4:1 (horizontal to vertical) with gentler slopes being desirable. Where space permits, slopes should be cut back to match existing grade. g.Rock rip rap should be provided at all points of juncture between two open channels and where storm sewer pipes discharge into a channel. h.The design velocity of an open channel should be sufficiently low to prevent erosion of the bottom. Rip rap or concrete liners should be provided in areas where high velocities cannot be avoided. i.Periodic cleaning of an open channel is required to ensure that the design capacity is maintained. Therefore, all channels should be designed to allow easy access for equipment. 2.4 Ponds a. Maximum allowed pond slopes are 3:1, though 4:1 slopes are preferred. Pond slopes steeper than 4:1 shall have erosion control blanket installed immediately after finish grading. In residential areas slopes no steeper than 4:1 shall be allowed. 3:1 slopes may be allowed in “maintained” areas as approved by the City Engineer. 3:1 slopes are not allowed for road fill sections adjacent to water bodies. b. All constructed ponds and wetland mitigation areas shall have an aquatic or safety bench around their entire perimeter. The aquatic bench is defined as follows: i)Cross slope no steeper than 10:1 LAND DISTURBANCE GUIDANCE DOCUMENT City of Mendota Heights, MN WSB Project No. 1734-04 Page 9 ii)Minimum width 10 feet iii)Located from pond NWL to one foot below pond NWL c. All constructed ponds and wetland mitigation areas shall have a maintenance access bench around sufficient perimeter to provide access to all inlets and outlets. At a minimum the maintenance bench should extend around 50% of the basin perimeter. d. Elevation separations of buildings with respect to ponds, lakes, streams, and storm water features shall be designed as follows: i)The lowest ground elevation adjacent to homes and buildings must be a minimum of two feet above the calculated 100-yr HWL or 1.5 feet above the EOF, whichever criteria leads to the higher elevation. ii)Landlocked lakes and wetlands require either 1) a five-foot separation between basin HWL and lowest ground elevation adjacent to building or 2) a three-foot separation between basin HWL for back to back 100- year storms and the lowest ground elevation adjacent to building or 3) three-foot separation between the highest known or recorded basin elevation in the case of large wetlands and lakes and lowest ground elevation adjacent to building. Whichever of the three methods yields the highest allowable ground at building elevation should be the one used. e. Drainage easements for ponds, lakes, wetlands, streams etc. shall encompass an area to one foot (vertical) above the calculated 100-year HWL. f. Maximum pond wet volume depth is 8 feet; minimum wet volume depth is 3 feet. g. Flood bounce is defined as the vertical difference between pond NWL and pond HWL. Flood bounce shall not exceed 6 feet except in the case of regional basins, as defined by the City Engineer. h. All ponds shall have outlet skimming for up to the 5-year event. i. All ponds shall be graded to one-foot below design bottom elevation. This “hold down” allows sediment storage until such time as site restoration is complete. j. The top berm elevation of ponds shall be a minimum of 1.5 feet above the 100- year pond HWL. k. Grading shall not block or raise emergency overflows from adjoining properties unless some provision has been made for the runoff that may be blocked behind such an embankment. l. Seeding around ponds should be MnDOT standard mix 33-261 or BWSR equivalent. LAND DISTURBANCE GUIDANCE DOCUMENT City of Mendota Heights, MN WSB Project No. 1734-04 Page 10 3.0 Stormwater Management Performance Measures 3.1 Volume Management a. For development and redevelopment projects, the performance benchmark for runoff volume reduction, otherwise known as abstraction, is a volume equivalent to 1.1 inches of runoff off all new impervious surfaces. Allowable BMPs for abstracting runoff volume and methods for calculating abstraction are: i) Infiltration benches adjacent to constructed ponds ii) Rainwater gardens or infiltration areas separate from ponds such as depressed medians or grassed areas adjacent to parking lots and buildings iii) Pervious pavement or pavers iv) Vegetated swales v) Constructed wetlands vi) Underground storage with infiltration vii) Underground storage with water recycling for irrigation viii) Green roofs b. For public linear projects these standards shall apply only to newly created impervious surfaces that exceed 10,000 square feet. c. The amount of impervious surface increase on projects shall be reduced to the greatest extent possible for development and redevelopment projects in accordance with Low Impact Development (LID) techniques. A narrative shall be provided that addresses the consideration of LID techniques in development and redevelopment impervious surface extents. d. For all infiltration calculations the infiltration rates in Table 3.1 shall be assumed. As an alternative, percolation tests can be conducted and submitted to determine the actual rate of infiltration after subgrading is complete.

Infiltration areas shall be designed to infiltrate water in 48 hours. LAND DISTURBANCE GUIDANCE DOCUMENT City of Mendota Heights, MN WSB Project No. 1734-04 Page 11 f. Infiltration areas shall not be constructed in karst or fractured bedrock areas, nor should they be constructed adjacent to steep slopes. g. Infiltration practices shall be left off-line until the upgradient drainage areas are stabilized. h. The volume management standard is waived in areas of known soil contamination or for developments where the potential for spills makes infiltration inadvisable. i. Infiltration areas shall not have a 100-year design storm flood bounce that exceeds 3 feet. j. Pretreatment, in the form of forebays or filter strips, shall be considered for all infiltration areas. k. For infiltration benches adjacent to ponds the following standards apply: i) Benches shall have slopes no steeper than 6:1 over the proposed infiltration zone. A slope of 10:1 is preferred. ii) Benches may be excavated and backfilled with sand or sandy topsoil to provide additional storage volume for infiltration without violating the 3 foot flood bounce requirement. l. Porous pavement or pavers shall be considered pervious surface for the purposes of infiltration calculations. m. Porous pavement or pavers are considered sufficient to infiltrate water off impermeable surfaces at a ratio of 5:1 (impermeable surface area to porous pavement area). 3.2 Water Quantity a. At a minimum, proposed peak runoff rate from development and redevelopment project shall maintain or decrease existing flow rates for the 2, 10, and 100-year 24-hour rainfalls. Table 3.2. Storm Events Event Rainfall/Snowmelt depth (inches) 2-year, 24 hour 2.81 10-year, 24 hour 4.19 100-year, 24 hour 7.47 100-year, 10 day snowmelt 7.2 b. A Rate Control Plan shall be developed for projects that disturb one or more acre of land. Public Linear Projects shall be exempt from developing a Rate Control Plan unless the project creates 10,000 square feet or more of new impervious surface. Rate Control Plan shall include the following items: i) Delineation of the subwatersheds contributing runoff from off-site, and proposed and existing watersheds on-site. ii) Delineation of existing on-site wetlands, shoreland, and/or floodplain areas. Any removal or disturbance of streambank and shoreland vegetation should be identified and avoided. Any unavoidable removal or disturbance to this vegetation must be addressed and mitigated iii) Stormwater runoff volume and rate analyses for existing and proposed conditions iv) Administrative items included in Section 4.0 v) A narrative describing existing and proposed rate control for the site. Detention basins shall be designed with capacity for the critical 100-year event, which is defined as the 100-year event that produces the highest water level among a 2-hour, 6-hour, 12-hour, or 24 hour rainfall events or the 10-day, 7.2- inch snowmelt runoff event. c. The maximum duration for rainfall critical event analysis shall be 24 hours except in cases where basins are landlocked, where back to back 24-hour events and the 10-day 7.2-inch snowmelt runoff event shall also be used. In all cases a hydrograph method of analysis LAND DISTURBANCE GUIDANCE DOCUMENT City of Mendota Heights, MN WSB Project No. 1734-04 Page 12 should be used. For the 24-hour rainfall event, or back to back 24-hour rainfall events, an MSE 3 distribution should be used. For shorter duration critical events other distributions may be used with the approval of the City Engineer. d. All drainage system analyses and designs shall be based on proposed full development land use patterns. e. Development adjacent to a landlocked basin and the basin is not provided an outlet, freeboard should be determined based on one of three methods (whichever provides for the highest freeboard elevation): i) Three feet above the HWL determined by modeling back to back 100- year, 24- hour events, ii) Three feet above the highest known water level, or iii) Five feet above the HWL determined by modeling a single 100-year, 24- hour event. f. When modeling landlocked basins, the starting water surface elevation should be the basins Ordinary High Water elevation, which can be determined through hydrologic modeling or, in the case of a DNR regulated basin, from a DNR survey. g. For basins with a suitable outlet, freeboard will be 2-feet above the HWL determined by modeling the 100-year critical event. Emergency overflows a minimum of 1.5 feet below lowest ground elevation adjacent to a structure should also be provided. h. Adjacent to channels, creeks, and ravines freeboard will also be 2 feet to the 100-year critical event elevation. 3.3 Water Quality a. Storm water treatment facilities constructed in Mendota Heights shall be designed according to the standards reflected in the MPCA publication Protecting Water Quality in Urban Areas, the State of Minnesota Stormwater Manual, and the design criteria from the National Urban Runoff Program. b. A 50% reduction in total phosphorous based on existing conditions must be shown for all development, redevelopment and public linear projects that exceed 1 acre of disturbed land, unless the requirements in Table 3.3 call for increased treatment capacity. Reduction in total phosphorus can be achieved using methods approved by the State of Minnesota Stormwater Manual, including but not limited to: infiltration, biofiltration/filtration, or stormwater ponds. c. In any case, the standard identified above that leads to the highest treatment capacity is the one required of any specific development.

Stormwater Management Plan Appendix E City of Mendota Heights WSB Project No. 1735-04 APPENDIX E Stormwater Modeling Development and Results Appendix E Stormwater Modeling Development and Results 1. PURPOSE AND GOALS The purpose of updating the City’s stormwater models to Atlas 14 is to determine the threshold of concern regarding Atlas 14 high water levels and policies to guide the City’s response to areas where flooding has been identified. Another priority for the City is to have a P8 Urban Catchment water quality model. 2. PROCEDURES AND METHODS The 2006 HydroCAD model was updated for this 2017 Surface Water Management Plan to accommodate for the new National Oceanic and Atmospheric Administration (NOAA) Atlas 14 Precipitation Frequency Estimates. The updated HydroCAD model was used to develop a P8 Urban Catchment Model. 3. HYDRAULIC ANALYSIS 3.1 HydroCAD The City of Mendota Heights provided the following HydroCAD models: Gun Club Lake Watershed (includes 42 subwatersheds and 22 stormwater ponds) Ivy Falls Creek and Mississippi Bluffs Watershed (44 subwatersheds and 16 stormwater ponds) Interstate Valley Creek Watershed (includes 118 subwatersheds and 66 stormwater ponds) The models include unique subwatershed IDs that correspond to a unique pond name. Figure 1 shows each of the subwatershed areas and corresponding ponds. The overall modeled drainage and stormsewer network is also represented. The City also provided a GIS database containing stormsewer information that was used to update the model. Pond outlet data, where available, was incorporated into the HydroCAD model. The following Atlas 14 storm events were used for the HydroCAD modeling effort: 2 year, 24 hour storm event = 2.81 inches 10 year, 24 hour storm event = 4.19 inches 100 year, 24 hour storm event = 7.47 inches The storm events were obtained from NOAA and use an MSE Type 3 distribution. Drainage areas, CN values and Tc values were included in the models provided. The updated model included reviewing and correcting drainage area boundaries and land use information when discrepancies were found between the model and on-the-ground conditions. There were very few areas that were modified. The primary objective of modifying the HydroCAD model was to have the ability to model the larger Atlas 14 storm events. This included updating pond stage/volume rating curves, along with adding overflow elevations and routing. GIS software and Lidar data were used for determining this information. 3.2 P8 The updated HydroCAD model was used to develop a corresponding P8 model for each of the drainage areas. A discussion of the parameters used in the P8 model is provided below. P8 parameters not discussed were left at the default setting. P8 version 3.5 was used for the modeling. Time Steps Per Hour (Integer) – 4. Selection was based upon the number of time steps required to reduce the continuity errors greater than two percent. Minimum Inter-Event Time (Hours) – 10. The selection of this parameter was based upon evaluation of storm hydrographs to determine which storms should be combined and which storms should be separated to accurately depict runoff from the pond’s watershed. It should be noted that the average minimum inter-event time for the Minneapolis area is 6. Snowmelt Factors—Melt Coef (Inches/Day-Deg-F) – 0.06. This coefficient is within the lower end of the recommended range and was selected to minimize the disparity between observed and predicted snowmelt (i.e., the coefficient lessens the number of inches of snow melted per day and increases the number of snowmelt runoff days). Snowmelt Factors – Scale Factor for Max Abstraction – 1. This factor controls the quantity of snowmelt runoff (i.e., controls losses due to infiltration ). Selection was based upon the factor that resulted in the closest fit between modeled and observed runoff volumes. Particle File Selection – NURP50.PAR. The NURP 50 particle files was found to most accurately predict phosphorus loading. Air Temperature File Selection – MSP4999.tmp. The temperature file was comprised of temperature data from the Minneapolis-St. Paul International Airport during the period from 1949 through 1999. Depression Storage – 0.02 inches (assumed, based on average watershed slope). The surface area and dead storage volume of each detention pond was determined using GIS software and Lidar data. Pond outlet and stage/discharge information was taken from the updated HydroCAD model. Infiltration was assumed only for ponds that appear to be dry, or are known to have a normal water level lower than the outlet elevation. GIS software was used to determine the directly connected and indirectly connected impervious areas for each of the modeled ponds (devices). WinSLAMM land use descriptions and the associated watershed fractions were applied to each of the subwatershed areas to determine a composite area for indirectly and directly connected impervious areas. Pervious area curve number values were taken from the updated HydroCAD model. An impervious runoff coefficient of 98 was used in the model. The water surface area for each of the ponds was routed to each device separately, assuming that the entire water area was directly connected with zero loading to each pond. It was assumed that all of the directly connected impervious areas were not swept. 4 Results HydroCAD and P8 results are summarized in Table E.1 included in this appendix. Output data is grouped by drainage area and tabulated for each individual subwatershed.
