CITY OF MENDOTA HEIGHTS DAKOTA COUNTY, MINNESOTA I717=.`1.�1►1177��77�r/ YT�J►[KI]151u I GY.Y [�7 Yu 11►1111 Y DG`l MARCH 11, 2003 The regular meeting of the Mendota Heights Parks and Recreation Commission was held on Tuesday, March 11, 2003 in the Council Chambers at City Hall, 1101 Victoria Curve. The meeting was called to order at 6:30 p.m. The following Commissioners were present: Chair Richard Spicer and Commissioners Stan Linnell, Larry Craighead, Raymond Morris, Paul Portz, Missie Hickey, and Dave Libra. City Staff present were Parks Project Manager Guy Kullander, Recreation Programmer Teresa Gangelhoff, and Administrative Assistant Patrick C. Hollister. Mr. Hollister took the minutes. This meeting was televised by NDCTV and replayed the following Friday at 1:00 pm and 7:00 pm. The following residents were in the audience for the skateboard park discussion: Tim Meyers 2334 Swan Drive Stephenie Reierson 2334 Swan Drive Michael Johnson 2300 Lexington Avenue South MINUTES Commissioner Morris moved to approve the February 11, 2003 minutes with revisions. Commissioner Libra seconded the motion. AYES: 7 NAYS: 0 TILSENBUROW FARM Mr. Kullander introduced an application from Tilsen Homes, Inc. for a Subdivision Approval and Wetlands Permit for the creation of seven single-family lots at 1875 Victoria Road (Planning Case #03-09). Mr. Kullander reminded the Commission that the City's parks dedication policy stipulated that the City may require either $1500 per new lot created or ten percent of the land at the Council's discretion. Mr. Kullander added that the Council could also accept other park improvements or recreational amenities in lieu of cash or land if they so choose. Mr. Kullander said that at $1500 per new lot, the total cash contribution would be $1500 times six, or $9000. When asked, Mr. Kullander speculated that ten percent of the total value of the land would be something in the neighborhood of $50,000. Mr. Kullander called the Commission's attention to a letter metal ramps were more attractive to him from a maintenance standpoint, although he was aware that many skateboarders preferred skating on a composite surface. Mr. Tim Meyers told the Commission that he would favor a composite surface over a metal surface. Mr. Meyers said that the metal park in Eagan generates a lot of complaints from the kids who use it because the ride is not as smooth, and there are often indentations at the transition areas between the metal and the wood components. Mr. Meyers said that his friend who builds skate parks with composite materials has a warranty, but the warranty is void if bikes are allowed on the surfaces. Mr. Meyers also pointed out that Fort Snelling State Park is in the process of installing a 90,000 square foot skate park. Chair Spicer asked who built the Eagan skate park. Mr. Kullander said that it was Skatewave, which makes anall-steel product. Chair Spicer explained the following dilemma to Mr. Meyers. Chair Spicer said that he was aware that kids prefer a composite surface to skate on, but that such a surface not only costs more money for initial installation, but also costs more in the long run for maintenance. Chair Spicer said that the choice might come down to whether the City should install a metal park with more components, or a composite park with fewer components. Mr. Meyers said that in that case, he and other skaters would prefer a composite park with fewer components. Ms. Stephenie Reierson said that she is a beginning skateboarder, and that she prefers a composite surface to a metal surface. Ms. Reierson said that a metal surface gets too not in the summer. Ms. Reierson said that she grew up in Hibbing, where they have a composite skate park, and it is superior to the metal surface. Commissioner Linnell pointed out another advantage to a composite surface. Commissioner Linnell said that a composite surface is quieter than a metal surface. Mr. Kullander said that the newest generation of steel ramps is quieter than the older steel ramps. The Commission asked Mr. Kullander to get three bids for skate park equipment. Two of the bids should be for composite materials, and one bid should be for steel. The Commission asked Mr. Kullander to specify the budget limit of $22,000 to see what that amount could buy. The Commission also asked Mr. Kullander to invite the skateboarders who have attended recent Parks and Recreation Commission meetings to provide their input. At the suggestion of Mr. Meyers, the Commission also asked Mr. Kullander to contact the cities of Oakdale, Shoreview, Eagan, and Shakopee to discuss their experience with maintenance issues of steel and composite materials. UPDATES Staff provided updates on the following items: • Recreation Programmer's Update • Wentworth Warming House • Dakota County Farmland and Natural Areas • Police Report (No incidents during February 2003) OTHER COMMENTS None. ADJOURN Motion made to adjourn by Portz and seconded by Linnell. AYES: 7 NAYS: 0 The meeting adjourned at 8:22 p.m. 5 City of Mendota Heights Id�IMUOA:L1LIfA nl April 2, 2003 Memo to: Parks and Recreation Commission From: Guy Kullander, Parks Project Manager Al Subject: Bids for Skate Park Obstacles Background: In March, after reviewing vendor information and listening to citizen input, the Commission directed staff to request bids for both skate park obstacles that are totally constructed of steel (with steel skating surface) and obstacles constructed using a steel structure and a wood -composite skating surface material (SkateLite Pro). The Commission further requested staff to invite supporters of the skate park to help select the obstacles and develop a layout for the skate park. A representative from SkateWave (an all steel product) was invited to work with the supporters to arrive at an acceptable layout so that a list of obstacles could be developed. This layout and the obstacles required were to be used as the basis for the bid request sent to vendors with instructions to bid comparable obstacle and/or components. Thirteen youth, four parents along with Commissioner Spicer and Portz the design session held at City Hall on Thursday, March 20th from 4:30 to 6:00 pm. Discussion: Bids will be received until 2:00 pm, Tuesday, April Stn and presented to the Commission for review that evening. Action Required: If the Commission selects a preferred vendor, they should make a recommendation to the City Council for consideration at the April 15t", 2003 council meeting. Note: If fhe ClEy Council awards the bid on April 15�h, staff will proceed with preparation of the site. This work will include installation of a ten -foot wide gafe into the court area, signage, relocation of portable toilet closer to skate park area, installation of one "street light' at the entrance to the parking lot and removal of the net poles. FIRM BY: OFFICAL ADDRESS: INSTRUCTIONS TO BIDDERS The Mendota Heights Parks and Recreation Commission has directed staff to seek bids for Skate Park components based on a design / layout developed with input from local skate enthusiasts. A representative from Earl Anderson, representing Landscape Structures, worked with the Park Commission and members of the community to arrive at a desired layout (see attached). The Commission wishes to receive bids from both vendors that supply an all steel product with steel skating surface and from vendors that provide components using a steel support structure with a SkateLite Pro skating surface that is fastened to the support structure with bolts (screws will not be accepted). The components bid should have the same characteristics (railings, side panels, etc.) as illustrated on the attached drawings. The Parks and Recreation Commission, on April 8`h, 2003, will review all bids submitted and make a recommendation to the City Council for consideration and award of this project on April 151h, 2003. /f you have any questions regarding this request for bids, contact Guy Ku//ander at City Offices.

Attached is an memo I directed to City Administrator, Cari Lindberg, which she provided to the City Council last Friday. Discussion: The Commission may want to consider the suggestion made by the School District concerning user fees for groups that reserve City fields. In 2002 the total revenue from user fees collected for reservation of City maintained fields (primarily at Mendakota Park), picnic shelters, and concession buildings was approximately $2,000,00, Mendakota Park was reserved fifteen weekends last year for tournaments, playoffs and our Parks Celebration, Action Required: None. CITY OF MENDOTA HEIGHTS MEMO DATE: March 25. 2003 TO: Guy Kullander FROM: Teresa Gangelhoff-Recreation Programmer SUBJECT: School Dist. 197 summer ballfield/soccer maintenance DISCUSSION: I made a phone call to Mark Fenton who is the grounds supervisor for School District 197 and asked him if he had put any policy in force for the upcoming summer (2003) field maintenance. He said a letter went out to all the associations that use the school districts ball and soccer fields inquiring if they would be interested in pooling money together from the associations to pay for summer help at a cost of $10,000.00 for the maintenance of school fields. He has not heard back from any of them yet. Because of budget cuts in the school district he said that they cannot afford to hire summer help but that they would still be mowing the fields but would not be dragging or painting lines etc... The exception is the two softball fields, one baseball field and one soccer field that they are in partnership with the City of Mendota Heights. They will still be cutting and dragging those fields in the agreement with the city. These fields will not be lined. He said they are looking at starting to charge anyone for the use of the fields or any facility in the school district. He said other cities are doing the same. He also mentioned that West St. Paul Parks and Recreation is also interested in what they are going to charge as they may start the same policy in their city and he thought it would be good if both cities and the school district would all be on the same page eventually in what we should charge organizations that want to use the fields or facilities. He said this is all in the works yet and nothing has been finalized except the fact that they will not be maintaining the fields as stated above for this summer. He is waiting to hear back from the organizations before making any final decision on a fee. ew:r re•.' - - .l,: _ -- _ _ wy-- _ tF;'-_�..`x' �s,__._--_„ \ E 1 ? a ra 4._ 3: 't�,+-+ra'.5 4' 0� 5 EE �•t' 'fq�%' 12f1 ="tit- it f52i ^v''t42 IF 35`4 i'6 1'00 ; 'dAS 4 I�i1 }; t •u,-.--• AI.'^-.....��-mac ate- w�'�'._ - oxa,__¢...---,•.--•,-;s;H�,....� x t. - J qN , i �'t1 if .: - Y '..1• t,,,". °'"1�ti4/'i; i<e'eyvf�"Jl f Gfik`_�, +Q E,-e.+�.-.�. lee dtIN i.'4'--{i,, "y �+ :r: -'1 o_v'k', t1t� - / b?'tv A. ll rotor-':s-- n f.•__,i•. 4r _T + No—•1 9E tPJl yt 5 ' �cp - _ 6s`h. c - !"r {.h v!Y= _ a 'ir n , ?� Ae '- Ft< Ali m t Sr % ; ii -_ 1t C [ t' ,,,,•_,.2 }`r,jt�'3"''Yi{fiJNN�t �.iI�JST'J..rFtA'" „r� `'•„`+. a�,-'£f r'".�a',2y rr tp,�•a f_r=3_ "G7 :'121 F -;a; :J .1 % if - e '.h yry r�-v.. s� ' J '"^.3,+yF.'c en >�'^-�+.t K" S .�...._ ; ' E _ l t .y ggl�•:.t.,;,,Q'i ze- J' a' :3) h INWy7 t' *+"_<'9,d ,a,,-'�' + i fr `,', �•' ee ,-r 4'S _,;�`•r ry! <s�-,--.",+.9- 0��,1� .it "`',..fell �_ `� fir. ,'-_..

L ke the trail, the history, culture, environment and economic possibilities are woven together. Creating a design for all of the open space areas is the first plan of action. This will enable the com- munity and its existing partners to identify various opportunities for funding and other partnerships to help manifest a dream into reality. Maybe the work through community forestry will spark more efforts —efforts that could create a 30-mile bike trail that traverses the countryside spurring more opportunities for local B & B's, or the creation of a downtown art center that will help to make Hendricks a wonderful destination. Urban forestry holds within it the opportunity to help communities realize a vision for the future while still holding on to the past. It enfolds within it the opportuni- ty to create who you want to be without leaving behind who you are. And, it manifests the best of what is possible. Urban forestry isn't just about trees, it's about people. People working together for the future. Janette Mane¢r is Tree Trust's Director of Outreach Program. Volunteers mulch newly pluroted flowers 4" deep, trees and shrubs 6" deep. Over 55 volunteers fro the Hendricks community worked planting trees and per flowers. Hendricks Beautification Commitee members volunteered long hours on all aspects of the partnership. Even so, they happily finished up the job of hauling 95 cubic yards of woodchip mulch. ®®O Hendricks, from p, i The Minnesota Design Team, formerly known at the Gover- nor's Design Team, is a group of dedicated professional volunteers whose passion and commitment are around sustainable communi- ty development. Since 1983 the Minnesota Design Team has visited more than 80 com- munities, working to develop a shared vision for the future. When the team 12 to 20 experts come into a community, they listen to as many people as possible, so that all views and hopes for the future can manifest in the vision that will be presented at the end of the weekend. Weaving the community's input into design concepts, drawings, and explanato- ry notes, the Design Team leaves behind a collective vision on poster -size drawings that interpret the common ty's shared vision. This vision then helps the community to start to identify and put together a plan of action that will help retain their existing community character and historic roots but moves them towards renewal —both economic and environmental. It was after the MDT visit that Minnesota Project, Tree Trust and the MDT got together to examine how we could help communities implement some of their new ideas and manifest their energy and enthusiasm into realistic plans. With an OEA grant, we were able to work with the City of Hendricks and together we have plant- ed more than 136 trees and shrubs, and hundreds of flowers, with the help of the Minnesota Dept. of Transportation's Partnership program. Working with the community, Tree Trust has also been able to identify how urban forestry can be integrated to create more economic stability. A hard-working community task force has identified several open space planting opportuni- ties and has looked at connecting them with a cir- cular trail that starts at the City Hall information center and continues past the school, hospital and one of four Lutheran churches to a potential 12 acre arboretum site, then meanders down main street, past an area for the sculpture garden, on to the history center and into Lake Hendricks park. 's age of tomato seeds denotes resistance to the dis- eases UerticIllium wilt, Fusarium wilt and root knot nematode. In understanding what resistance is, it is important to remember that a resistant plant can still be infected by a given pathogen. However, the resistant plant is less likely to become serious- ly infected than a "susceptible" counterpart. Why? You ask. What makes one plant resistant and not another? Some factors that contribute to resis- tance include thicker leaf cuficle (the waxy outer coating of the leaf), smaller stomates (gas ex- change pores), and the ability to make enzymes that destroy toxins needed by pathogens to infect. Resistance isn't the only trait that breeders seek to incorporate into new cultivazs. In some instances, tme resistance to a given disease is not available, but [he ability to tolerate a disease is. Tolerance, unlike resistance, is the ability to with- stand infection, even at high degrees, and still yield or not be killed. Unfortunately, most people confuse resis- tance with immunity. Immunity is described as the inability of a pathogen to cause disease. For example, it is impossible for an ash tree to get Rhizosphaera needlecast of spmce. The ash is said to be immune to the disease. Crabapples, like most plants, are immune to most diseases. As such, crabapple will never become infected with citms canker, wheat leaf rust, or soybean sudden death syndrome. Crab- apple is commonly infected with many diseases, including fire blight, cedar -apple mst and scab. In Minnesota, one of the most serious diseases affecting crabapples is scab. Figure 2. Symptoms of apple scab first appear as diffuse, olive to dork gray, velvety lesions on leaves and fruit. Pity the homeowner who has a tree that is susceptible to apple scab. In August, just when that homeowner desperately is wishing for shade, their tree, their pride and glory of May, is com- pletely defoliated (Fig. 1). They are raking up spotted leaves and moldy fmit in August and hat- ing every minute of it. The homeowner talks to his neighbor across the street, who also has a crabapple. Her crabapple also looks gorgeous in spring, but keeps its leaves until a proper time in autumn. Even its fruit "behaves," and stays on the tree, looking like brilliant red ter long.

Although some homeowners worry that the tree has died due to defoliafion, scab does not kill the tree outright. Instead, it slowly weakens the tree over time, and increases the likelihood of infection by opportunisfic insects or pathogens. Scab can be managed through intensive fungicide use, with sprays being applied every 10 to 14 days throughout the growing season to achieve effective control (Fig 3, following page). For this reason, most homeowners are encouraged to select and plant scab -resistant cultivazs. A num- ber of cultivars with high levels of resistance to scab are available. The culfivaz in our story, "Christmas Holly," is described as slightly suscep- tible to scab. But why did it take ten yeazs before the disease struck? Crabapples, io p. 6 ADVOCATE Wmier 2003 5 by Patrick Weicherding, Regional Extension Educator -Metro District inching trees and shrubs is a rec- ommended cultural maintenance practice with many benefits. Mulch: ® Reduces soil moisture loss via evapo- ration. ® Minimizes weed competition when applied more than 2 inches deep. ® Moderates extremes in surface soil temperatures. 0 Improves plant growth and vigor. ® Reduces soil compaction and erosion. ® Improves soil aeration and soil stmc- ture. ® Minimizes frost heaving of small transplants. ® May increase soil fertility. ® Can reduce salt buildup. ® Reduces reflection and re -radiation of heat. ® Reduces the incidence of some diseases. ® Is aesthefically attracfive. Despite these benefits, mulch can literally kill plants if it is applied improperly. A "volcano" of mulch, piled high against the trunk of a tree may not kill the tree immediately, but it can kill over time. .•• ® L®w Ottygetee Suffocafion of tree and shrub roots is the most common cause of death from over -mulching. Repeated applications of mulch can con- tribute to a waterlogged soil/root zone by slowing soil water loss via Mulch "volcanos" — wood chips piled against tree trunks —are a misuse of mulch that leads to o plant's decline and eventual death. ®®O Mulching continued on p. 8 ADVOCATE • Wm�«2003 tious inner bark. This often goes unnoticed until the following spring when the "tree doesn't look so good." If the trunk is girdled (that is, over 50% chewed around the trunk), there is little that can be done to save the plant outside of bridge grafting. Many "green" or non -aged types of mulch may cause nitrogen deficiencies in young trees and shrubs. Decomposing bacteria and fungi which ultimately break down mulch must have an ample supply of nitrogen to do their job. Most landscaping mulches are composed of bark or wood residue which have high carbon to nitro- gen ratios and have very little nitrogen available - for the decomposing bacteria. Hence, the bacte- ria in the soil utilize the existing nitrogen to break down the mulch. This process may cause nitrogen deficiencies on new growth. Although nitrogen deficiencies may occur, they are usually considered temporary as the mulch will eventual- ly release its nutrients into the soil and the decomposition will -taper off. u "Sour" mulch can occur when finely ground mulch is piled so high (usually greater than 10 feet) that inadequate air exchange occurs in the center of the pile. Without adequate oxygen, anaerobic microorganisms become active and produce several organic acids and alcohols, caus- ing the mulch to give off pungent odors and pro- duce extremely acidic pHs ranging from 1.9 to 4.8. Such mulch is highly toxic to plants —espe- cially recently transplanted woody. ornamentals. If mulch smells bad or is extremely acidic, don't use it until it is properly composted. Allelopathic toxins aze compounds produced by plants that inhibit the growth of other plants. Such substances might be present in mulch, depending on the source. The classic example of allelopathy is the black walnut (Juglarts nigra). It produces juglone and juglonic acid, which inhibit the growth of many plants. Juglone is found in all parts of the plant. Therefore, fresh wood chips and sawdust from black walnut should not be used as mulch unless well composted. Even then, small amounts ofjuglone can be detected. Besides black walnut, other allelopathic mulches include uncomposted sawdust of red- wood (Sequoia) and cedar (Cedrus); the bark of spruce (Fite¢), larch (Larix) and Douglas fir (Pseudotsuga). Mulching is one of the best —and maybe one of the worst —things you can do for your trees and shrubs. Mulch depth should not exceed 3 inches as a standard. However, on poorly drained soils, mulch depths should not exceed 2 inches, especially for shallow rooted plants. Wet soils may not need any mulch. Coazser-textured mulches can be placed a bit deeper due to better oxygen diffusion into the soil. Finer -textured mulch, such as double -shredded mulch, may need only a 1- or 2-inch layer. If you have a problem with excess mulch, dig through the landscape to see how deep the mulch really is. A light raking of existing mulch may be all that is needed to break _ _ _ through the crusted or compacted layers that can repel water. Pull mulch back from plant stems and trunks —a rule of thumb is 3 to 5 4''�����•^ �v`^.' inches away from young plants, and 8 to - 12 inches away from mature tree trunks. Visually look for the pres- ence of a root flare; if not visible, it maybe at least partially buried and must be exposed. Remove all soil or mulch up to the junction of the roots grid trunk collar (taking care not to damage the tender bark) to expose the root col- lar. Leave the resulting well open and exposed to air. Reseazch shows that an amazing number of plants have rapidly improved in color and vigor within months of root collar excavations. In conclusion, mulch may be "worth its weight in gold" but improperly used it may be "too much of a good thing."

Participants received packets with instructions about how to cut and stack brush, and how to treat the stumps after cutting. Free home visits by trained volunteers were offered to residents who needed help identifying plants that might have been missed by surveyors. Twenty-eight homes signed up to participate. A rear -loader compactor truck was hired from Aspen Waste Systems for $100 per hour, and NRG Processing Solutions, LLC, which is located in the neighborhood, disposed of the brash at no charge. The pickup began at gam on Saturday October 6 and was completed just after noon. Pickups were made by address, but volunteers could pickup unscheduled brush if they had fime. The truck driver worked alongside volunteers to load the truck, and 3 volunteers worked each of the two 2-hour shifts. A compactor truck reduces time lost in emptying non -compacting trucks, and saves time that would be spent in chipping, but compacting brush was slow. While waiting for the truck to compact each batch, volunteers were busy sweeping up twigs and thousands of berries. r��m�rr:�l�mlizrri Financing for Fulton included Neighborhood Revitalization Program funds ($6,000), a USDA Forest Service Grant ($1,000), and Minnesota Depaztment of Natural Resources Conservation Partnership Grant ($4,000). Fulton chose to go with a free curbside pickup for 3 years, with a goal of 50 households participating per year. Michelle Mensing, Neighborhood Coordinator, was in chazge of their project. Sixty households participated in the roundup. Fulton completed surveying 2/3 of their 2,000 households before their roundup, and twenty resi- dents had already signed up before the survey. Coordination of the event was handled by a 4-person committee, 10 volunteers surveyed pri- vate property, house calls were offered to resi- dents, and 6 volunteers worked on the pickup guckfihorn removal and chipping in 4he Linden Wills Neighborhood ®e® day. Residents donated the use of a truck and chipper. There was no formal cutoff date to sign up, but due to the high participafion, applications were cut off two days before the pickup date. Curbside pickup was scheduled by address, although brush not on the signup list was picked up along the way as well. Pickups stazted at lam on Saturday and con- tinued until dazk, about 7pm. An additional 3 hours were needed on Sunday to complete the collection. Equipment problems slowed things down because the truck and chipper were unable to keep up with the continual demand: Next time they plan to hire a professional tree service to handle hauling and chipping. Mensing believes that their "multi -angle" approach to publicity was important to their high pazficipation. They received the best response from the door hangers Left during the survey, and their neigh- borhood billboard was next in effectiveness. Additionally, posters, community newspaper arficles, sandwich signs, and the neighborhood organization's bimonthly newsletter all helped raise awareness of the buckthorn problem and the upcoming roundup. The Linden Hills Neighborhood In Linden Hills, the response was so great —over 168 residences partici- pated —that the pickup stretched over 4 days. Next time, Madalin Cioci, Linden Hills Neighborhood Council Implementation Coordinator, plans to keep it to one day. Funding included a USDA Forestry Service Grant ($1,000) and a Minnesota Department of Natural Resources Conservafion Partnership Grant ($8,000). Plans are to hold roundups each yeaz for the next two years.

Forest tent cater- pillazs are often mistakenly called "azmyworms". In the forest, FTC defoliation usually does not affect tree health because FTC populations usually collapse before tree damage occurs. FTC can consume 60% of a tree's foliage for three years and the tree will show no ill effect. Even completely defoliated trees will usually develop a second set of leaves in mid July without a loss in health. Widespread outbreaks of FTC occur at intervals of ten to twenty years and aze two to four years in duration. Outbreaks peaked in 1922, 1937, 1952, 1967, 1978, and 1990. Populations collapse due to stazvation, preda- tion and parasitism. Populations of the "friendly flies" (see sidebaz), native parasites, build up as the FTC populations peak. About 77 million acres were defoliated statewide in 2001. Hopes were for a decline in 2002, though extensive defoliation was still expected. �i.�t�'yjl��a The summer of 2002 brought the most serious defolia- tion in northern Beltrami County since 1954. Yet, the expect- ed defoliation predicted in and azound the city of Bemidji did not occur. Aspens, birch, and other hardwoods refoliated. The stench of rotted lazvae in the heavily defoliated areas slowly disappeared. �c�ztllxa Surveys of forest tent caterpillaz egg masses in central and northeastern Minnesota predict a sharp drop in caterpil- lars for most areas. The caterpillaz population will be high, however, in Deer River, Hibbing, Virginia, Finland, and Gooseberry Fall State Pazk. In addition to the egg mass survey, there are other clues that the forest tent caterpillars will decline in 2003. When the larval surveys of 2001 and 2002 were compared, the 2002 survey showed more dead caterpillazs, killed by disease, in more locations. There was also a great increase in the number of parasific flies. These flies mazk "the beginning of the end". They deposit living maggots on FTC cocoons. The maggots chew through the caterpillars' exoskeleton and feed on internal living fissues. Thus, the caterpillar is killed.

They propose to subdivide and develop this 17.5-acre site into thirty single- family lots. To accommodate the Council or Planning Commission, the developer may incorporate suggestions or comments into the final development plan they submit with their formal application. Discussion: The Park Dedication Fee for this parcel would be 1.75-acres of land or $45,000.00 (30 x $1,500.00). The southwest corner of this parcel touches a natural undeveloped corner of Valley Park. If this development proceeds the City has an opportunity to connect the neighborhoods (Park Place, Cherry Hills, etc) north of Wentworth to the Marie Ave. trails and Valley Park. The northwest end of this parcel abuts a short street section of Wachtler Avenue constructed in the mid-1980's. A trail from this dead-end street along the west end of the parcel would connect to the corner of Bachelor Avenue and Trail Road. Users of this trail segment (proceeding north to south) could continue on Trail Road to the existing trail on Marie Avenue that connects to the Valley Park trails going north to Hwy. 13 / Lilydale and south to Dodd Rd. & Hwy 110 (Town Center). The Planning Commission will review the Concept Plan on Tuesday, April 22"a followed by the City Council on Tuesday, May 5th. The developer will probably follow this meeting with a formal application that will go on the May 20th Planning Commission agenda and then on to the June 2"d Council meeting for final approvals. The Commission may want to consider directing any concerns or suggestions regarding this project to the Planning Commission or City Council at this time, or they may wish to request a formal presentation, by the developer, at the May 13th commission meeting. 0 17KAI L s ,o 0 fi7 City of Mendota Heights •-� April 7, 2003 Memo to: Parks and Recreation Commission From: Guy Kullander, Parks Project Manager 4V Subject: Park Dedication Fee for: Wagenknecht Background: The developer is requesting that an existing 1.85 side of k35 E, be subdivided into three lots, which would for the two additional lots. 1062 Wagon Wheel Trail acre lot, located along the west require Park Dedication Fees Discussion: The eight -foot wide bituminous trail way, proposed for Lexington Ave. & Wagon Wheel Trail, crosses the north side of this proposed project. The existing street right-of- way at this location is fifty feet wide, which is less then the normal sixty feet of most streets in the City. The lack of adequate right-of-way may require the purchase of additional land or an easement to accommodate construction of the City's trail. Recommendation: I recommend the Parks and Recreation Commission request the Planning Commission and City Council consider acquiring additional street right-of-way from this developer. I further recommend that the Commission accept a cash contribution, in the amount of $3,000.00 (2 x $1,500.00) for the two additional lots formed if this subdivision is approved. d _a cU MOMME W O X W U- LEXINGTON AVE. 1062 Wagon Wheel T unr%se Pr h 80 0 80 Feet N rl W E S - 3/10/03 City of Mendota Heights - mdF-- - ::4%;yip '. 1 _ _ z :.`.Fr z3 F II City of Mendota Heights MEMORANDUM April 8, 2003 Memo to: Parks and Recreation Commission From: Guy Kullander, Parks Project Manager Subject: Skate Park Bids - Review REVIEW OF BIDS = PRODUCT DESCRIPTION 1.
