Natural Resources Coordinator Krista Spreiter reviewed the Commission is asked to hear the Annual
Report given on the city’s Municipal Separate Storm Sewer System (MS4) permit and Surface Water
Pollution Prevention Program (SWPPP). Ms. Spreiter presented a PowerPoint.
The MPCA requires the City to maintain a Municipal Separate Storm Sewer System (MS4) permit. The
permit was renewed under the new 2020 MS4 General Permit. The goal of the MS4 Program is to
reduce the amount of pollutants entering state waters from municipal and other stormwater systems,
and ultimately protect our surface waters. As part of the requirement, the City must develop a Surface
Water Pollution Prevention Plan (SWPPP). There are six Minimum Control Measures (MCMs) that the
City is required to fulfill.
1. Public Education and Outreach
2. Public Participation/Involvement
3. Illicit Discharge Detection and Elimination
4. Construction Site Runoff and Control
5. Post-Construction Runoff Control
6. Pollution Prevention/Good Housekeeping
MCM 1: Public Education and Outreach - Educational Materials and information provided in Friday
News, Heights Highlights, and the City’s Website and on social media. Events, classes and programs
December 11, 2024 Mendota Heights Natural Resources Commission Page 2 of 7
such as Landscaping for Clean Water, the Fishing Derby, Trick or Teeing, and Earth and Arbor Day
Celebration.
MCM 2: Public Participation/Involvement – City must provide a minimum of one annual opportunity
for the public to provide input on the City’s SWPPP. The SWPPP is posted on the City’s Website. The
City hosts a rain barrel sale and cleanup event annually (Earth and Arbor Day) and will continue to
participate in Adopt-a-Drain, CAMP and WHEP.
MCM 3: Illicit Discharge Detection and Elimination – City must maintain a storm sewer map that
includes all pipes 12 inches or greater, outfalls, and structural stormwater Best Management Practices
(MBPs). Required regulatory mechanisms. Have a procedure that provides a means for, and tracks,
IDDE. Establish a regulatory mechanism that requires proper salt storage at commercial, institutional,
and non-NPDES permitted industrial facilities.
MCM 4: Construction Site Stormwater Runoff Control – Regulatory mechanism for erosion, sediment
and waste controls. Review site plans. Conduct site inspections every 2 weeks, and after every .5 inch
or larger storm event.
MCM 5: Post-Construction Runoff Control – Regulatory mechanism that establishes requirements for
post-construction stormwater management. Maintain a written or mapped inventory of public and
private structural stormwater BMPs. Ensure compliance and enforcement on new development.
MCM 6: Pollution Prevention/Good Housekeeping – Mapped inventory of City owned/operated
facilities that contribute to stormwater discharges. Inspect and maintain all City-owned facilities.
Inspect structural BMPs and outfalls annually. Inspect all stormwater ponds on a 5-year cycle. Perform
maintenance based on inspections. Implement/install permanent BMPs on City projects/municipal
operations. Maintain and implement written snow and ice management policy.
The public is encouraged to comment on the City’s Stormwater Pollution Prevention Program at any
time. The full report can be found on the City’s website or requested in-person at City Hall. Meeting
the goals for the annual permit coverage from the Minnesota Pollution Control Agency are covered
separately under the storm water utility fund. Stormwater improvement projects are presented to City
Council individually as required.
Commissioner Sheets referred to the landscaping for clean water program and noted the County does
offer grants for homeowners who are interested in going through the program. Ms. Spreiter stated
that is a great program. They offer classes and help planning projects.
Commissioner Fahnhorst referred to the clean water practices and asked how the process works for
construction. Ms. Spreiter stated it is required through the State that developers need to have their
own SWPPP. New impervious needs to have permanent stormwater treatment. This could be rain
gardens or infiltration basins. There is a guidance document for contractors that spells out the State
and City requirements. This can also be found on the City’s website.
Commissioner Sheets asked when residents spot something that they are not sure if they should
report. What should they look for? Ms. Spreiter stated if a resident sees anything but stormwater
runoff going down a storm drain the City should be notified. They could also report it to the State.
Clean-up efforts would be put into place as soon as possible.
Vice Chair Knosalla asked about the brine. Ms. Spreiter explained that it is a liquid mixture that is
December 11, 2024 Mendota Heights Natural Resources Commission Page 3 of 7
applied to the streets prior to a storm event to keep the ice from building up. Vice Chair Knosalla
stated that the mini-golf hole-in-one turned out beautifully. She commended Student Representative
Trudeau on her planning efforts.
Commissioner Sheets stated the outreach was keeping leaves out of the road and going into the storm
sewer. She asked if there is any additional guidance. Ms. Spreiter stated through adopt-a-drain there
are suggestions.
b. Interstate Valley Creek BMP and Stabilization Project Update
Coordinator Spreiter reviewed the Commission will hear a presentation on the status of the Interstate
Valley Creek Stabilization and Best Management Practice (BMP) project.
The City of Mendota Heights has partnered with Dakota County and the Lower Mississippi River WMO
to implement the Interstate Valley Creek Stabilization and Best Management Practices (BMP) project.
The project was coordinated with the timing of the River to River Greenway trail project, which is
planned to begin in May 2025. The purpose of the project is to replace degraded stormwater
infrastructure, provide additional stormwater treatment, and restore a wetland to aid in vegetation
management, reduce erosion, provide habitat, and restore wetland conditions that existed historically.
Ms. Spreiter reviewed a PowerPoint including:
Project Overview – A feasibility study was completed in 2023 to identify areas of streambank erosion
and potential treatment and infiltration areas in the watershed. The project includes stormwater
infrastructure repair, stabilizing three areas or reaches of the creek bed, installing two
filtration/infiltration basins, and installing a weir downstream of a wetland within Valley Park. The
project is funded by a Clean Water Grant, and is a coordinated partnership between the City, the
Lower Mississippi River WMO, and Dakota County.
A map showing the project area was provided for Commission review. A diagram showing the
infiltration basins was also shown. The locations for stabilization were also shown.
Commissioner McCaslin arrived at the meeting at 6:25 p.m.
Vice Chair Knosalla asked if construction will occur throughout the winter. Ms. Spreiter stated the
project officially may start as early as this week. There is some winter work that is slated to begin. Vice
Chair Knosalla asked if the residents in the area will be impacted by the storm sewer being
constructed. Ms. Spreiter stated the improvements, and construction will be on park property. There
are a few residents that will be close to the construction.
Student Representative Trudeau asked about the weir. Ms. Spreiter stated the purpose of the weir in
the channel which will create more wetland area upstream. This will allow for a volume reduction. The
spot with the severe erosion was indicated on the drawing.
Commissioner McCaslin stated is the plan to have two feet of standing water and Ms. Spreiter stated
the elevation would be two feet above where it is currently.
Commissioner Sheets asked how the wildlife will be affected that utilize the waterway and any
plantings. Ms. Spreiter stated it is designed to enhance wildlife. This will add more open water habitat.
The hope is to eliminate the reed canary grass.

6. Old Business
a. 2025 National Resources Commission Workplan
Coordinator Spreiter reviewed the Commission is asked to discuss the draft of its 2025 Work Plan and
December 11, 2024 Mendota Heights Natural Resources Commission Page 5 of 7
accept the draft as is or with amendments.
The Commission uses an annual work plan to accomplish its goals, as well as aid in accountability,
resource allocation and proceeding through commission priorities. A work plan may consist of goals,
priorities, tasks, programs, or projects that the Commission would like to implement in 2025.
Resources, monetary cost, timeline, and benefits of each identified item should be considered. The five
goals of the Commission are:
1. Ordinance and Policy Development
2. Education and Outreach
3. Urban Forestry and Restoration
4. Strategic Planning
5. Sustainability
Ms. Spreiter reviewed the initiatives under each goal.
The Commission is asked to use this time to discuss the existing items in the draft, make edits to the
draft, or add additional items if it so wishes. The 2025 Work Plan should be completed and accepted by
the Commission at this meeting or its regular meeting in January. The 2025 Work Plan draft was
provided for Commission consideration.
Vice Chair Knosalla noted goal 1 and goal 5 have the same initiative listed “Explore deconstruction
policy for city-owned buildings and facilities”. Ms. Spreiter stated it was discussed that some of the
initiatives may fall between more than one committee. Vice Chair Knosalla suggested noting which
committee is the lead and which is the supporting committee.
Commissioner Fahnhorst suggesting discussing further when Chair Swank is present.
Commissioner Sheets asked which Committee would be the lead on this and Commissioner McCaslin
stated he is not sure the policy is needed prior to the ordinance.
Commissioner Fahnhorst suggested starting it in the Sustainability Committee rather than Ordinance
and Policy Development. Vice Chair Knosalla suggested removing it from Goal #1.
Commissioner Fahnhorst asked if policies are published formally. Ms. Spreiter stated the City Council
can take official action by passing a resolution to adopt the policy. It is different than an ordinance.
The consensus of the Commission was that Sustainability would lead the effort with Ordinance and
Policy collaborating.
Motion to adopt the 2025 Work Plan with revisions by Fahnhorst, second by McCaslin.
Motion passed 4-0.
b. 2024 Tree Canopy Program Recap
Coordinator Spreiter reviewed the Commission is asked to hear a presentation and summary of the
2024 Tree Canopy Program. The proposal of a residential and/or commercial shade tree program was
brought to the commission for discussion in 2023 and approved by the Commission in January of 2024.
The proposal of a residential and/or commercial shade tree program was brought to the Commission
December 11, 2024 Mendota Heights Natural Resources Commission Page 6 of 7
for discussion in 2023 and approved by the Commission in January of 2024. The City entered into an
agreement with Tree Trust Landscaping, LLC to provide residents and commercial property owners
with a full-service tree purchasing and planting program in 2024. For the subsidized cost of $185 for
residents and non-profit property owners, and $259 for commercial property owners, accepted
applicants received a high-quality, 10-gallon tree or trees suited for local conditions and our changing
climate to be planted within their private property. Applicants were accepted on a first-come-first-
served basis with priority given to properties that lost a tree(s) due to Emerald Ash Borer, properties
located within an Environmental Justice Area (MPCA’s Environmental Justice Area), or those located
within a High Relative Heat Export area within Mendota Heights (Spring only). During the fall
application process, no priority was given due to the number of trees left for purchase.
The program included:
• A site consultation with City Staff on the best location for the new tree.
• Utility locate coordination prior to planting.
• Transportation of the tree and all planting materials provided by Tree Trust Landscaping
Services.
• Proper planting, mulching, and watering at the time of planting, provided by Tree Trust
Landscaping Services.
• A high-quality 10-gallon container tree, watering bag, tree protection and mulch to be placed
at the time of planting.
Options included:
• Blue Beech
• Hackberry
• Kentucky Coffee Tree var. Espresso
• River Birch
• Redbud (Minnesota Strain)
• Bi-color Oak
Participants were required to enter into a maintenance agreement with the City upon acceptance,
assuming responsibility for watering and all tree care after planting, including removal if needed, and
all costs associated with tree maintenance of the tree in the foreseeable future. Trees provided are
guaranteed for one year.
During the spring planting, 26 trees were ordered and planted through the program, with a one tree
maximum allowed per property address, and priority was given to those that qualified for one of the
three priority categories.
During the fall planting, 65 trees were ordered and planted. The priority categories were not
implemented, and the maximum number of trees per address was increased to two. The remaining
trees available (44) were planted in City parks as part of the City’s Emerald Ash Borer Bonding Grant
project. The cost of the program ($25,000) was paid through the City’s Tree City Fund. The Tree
Canopy Program will run through 2025.
Vice Chair Knosalla asked of the remaining trees was there a specific species that was not as popular.
She asked if reducing the price per tree would that encourage more interest in the program. Ms.
Spreiter stated the most popular were Red Bud.
Student Representative Trudeau asked if the City Tree Sale runs at the same time and Ms. Spreiter
December 11, 2024 Mendota Heights Natural Resources Commission Page 7 of 7
stated orders for both are done at approximately the same timeframe. Student Representative
Trudeau suggested if there is extra inventory they could be made available in the tree sale. Ms.
Spreiter stated City Staff would need to run that tree sale.
Commissioner Sheets asked if the prioritization for the Spring should be done in the future or should
the prioritization be changed. Ms. Spreiter stated her initial thoughts was no prioritization with
additional outreach done.
Commissioner Fahnhorst stated he is in support of the tree program. For the full service option at $185
that is a great deal. He is supportive of keeping the price as is for the second year. The tree selections
are good options.
Vice Chair Knosalla suggested the two different sales be communicated at the beginning of the year.
Commissioner Sheets also suggested providing educational resource information on the species
available.
7. Staff Announcements
