Marks and Recreation\Advisory Commission\Monthly Meetings\May 2304\Cover 2 DEPARTMENT HAPPENINGS May 2004 Recreation Division • Summer is in full swing for the adult sports programs and concessions. Softball has had two nights cancelled due to poor weather conditions. • The next focus for adult sports is getting the fall information put together and out to teams by the beginning of June for softball and the beginning of July for basketball, volleyball and touch football. • All Summer Recreation Leaders and Assistants are hired for this summer. There are 19 new staff and 26 returnees. • There are 500 children registered for Summer in the Park and Wagonful O'Fun programs so far this summer. • Youth Development after school programs are winding down. A total of 433 students registered for after school classes between our two sites. • The final week of programming at Pilot Knob will end with a Drama Performance the week of June 2. • 30% of the students at Pilot Knob are on free and reduced lunches. • 85% of the students at Glacier are on free and reduced lunches. • Survey response is up to 21% and very supportive of the programs. • Preparations have begun for 2004-2005 school year, for a potential of 4 sites targeted in low income areas. • Summer programs are being coordinated at Wescott commons, including a Wagon Full of Fun, Community Mornings and Court / Field games in the later afternoons. • Over 1300 Middle and High School students have walked through the doors of the teen center since it opened in September. This does not include the various rental parties that have taken place over the last couple of months. • Teen fitness programs have been very well received and repeated. • Eagan and Apple Valley's Battle of the Bands are full! Our Battle is scheduled for May 21• at the Rotary Band Shell. • The Eagan Teen Advisory Board has entered in to a fiduciary agreement with the Eagan Foundation. • The Eagan Teen Advisory Board has facilitated four successful and popular kid's night outs at the community center. 81 children have been registered. • The E-TAB has also volunteered at a few events: Dakota County Crisis Nursery fundraiser walk, Arbor Day planting, and Holz farm spring festival. • Other exciting upcoming events yet this spring and summer are: Pre-prom, capture the flag, wheel jam, cable classes, teen leadership, and the second annual film festival. Parks Division • The process of putting the "finishing touches" on Thresher Fields is underway. Construction has begun on Borchert Lane, the access road providing service to Thresher Fields Park. The road is being widen and paved, and the storm sewer upgraded. An 8 foot wide bituminous trail will be installed within the right of way for the entire length of the road. Dakota Electric has begun the process of installing security lights in and along the new parking lot. Given the cold fall of 2003 and the subsequent stunting of turf growth, a fall 2004 opening is becoming more unlikely. • The Arbor Day event held at Central Park on Saturday May P was a great success. Approximately 80 people took part in the tree and shrub planting and poster presentation. A number of City dignitaries including the Mayor and three council members took part. APrC members Terry Davis, Margo Danner and the "Grill Master" Joe Bari provided much appreciated assistance with cooking and serving the noon time lunch. Many thanks to Gregg Hove and his staff for another great event. 3 • Park staff began mowing in earnest the last week in April. Over 500 acres of turf and 70 miles of boulevard are mowed on a regular basis. When fully staffed, a fleet of 11 mowers is sent out daily. Due to reductions in aid to local governments, 6 seasonal positions were eliminated, and the filling of a vacant full time maintenance position delayed. The result will be less frequent mowing of boulevards (from an ave. of 2.5 times per month to 1.5) and reduced trimming in the parks. Some "shaggy" edges may become evident as the grass grows. • The. process of fertilizing park areas is underway. Once again a high quality, slow release, 0% phosphorus material is being used in most areas. Products with a minimal amount of phosphorus are being used in areas shown through soil tests to be deficient. • With the growth of grass comes our yellow friends, the dandelions. The Park department does do selective and contractual spraying at sites throughout the City, particularly athletic sites and City buildings. The product used becomes safe for contact once it has dried, generally in a matter of minutes. Dandelions, while a nuisance, are not considered noxious, therefore total eradication is not mandatory. Seeds can be carried for a great distance on even a gentle breeze. • A final walk through of the new Thomas Lake building with the architect and builder was completed. Only some minor punch list items remain to be completed prior to the end of May opening. • At a workshop on May 11, the City Council gave approval to the proposed 2004 Parks Department Capital Equipment Program with only a sun-shelter proposed for Wescott Commons held over for further review. Work on a number of the projects is underway. The APrC was well represented with 6 current members and 2 new members present. • Representatives of the DNR grant program conducted a walk through of the proposed Caponi acquisition property. By all indications they were impressed with the property however significant funding for the grant program from the legislature appears to be doubtful. The entire metro area may have only $500,000 available for grant purposes. A final decision on all of the City's applications is expected in June or July. 4 Date: May 17, 2004 Agenda Item: G-1; Grand Oak Five ~w. . L f 7_. r Action X ti City of Eagan Information Parks and Recreation MEMO Attachments X 1. Location Map 2. Preliminary Plat AGENDA ITEM: G-1; GRAND OAK FIVE TO: ADVISORY PARKS COMMISSION PREPARED BY: PARKS AND RECREATION STAFF ITEM OVERVIEW: Review the parks dedication, trails dedication, tree preservation, water quality and wetlands issues that pertain to the Grand Oaks Five development. BACKGROUND/HISTORY: The applicant is requesting approval of a Rezoning from BP, Business Park to PD, Planned Development, a Preliminary Subdivision (Grand Oak 5) of approximately 14 acres to create 4 lots and a Preliminary Planned Development to allow development of approximately 140,000 SF of office and 16,000 SF of retail/restaurant for property located at the northwest intersection of Highway 55 and Highway 149 in the East '/2 of Section 2 The subject property is located in a redevelopment area and contains a mix of current uses ranging from outdoor storage to offices for TMI Coatings. The City has acquired the properties in question and will be selling the same to Interstate Partners in the near future. The applicant has developed the Grand Oak Business Park over the last several years and. is looking to complete the park with additional office space and retail service uses that will benefit workers in the park and this area of Eagan in general. This item is scheduled for a public hearing in front of the APC on May 25, 2004 and is scheduled for the June 15, 2004 City Council meeting. This is 120 day application. The request to rezone to PD, Planned Development will be reviewed against the intent of the Planned Development Zoning District listed below: 1. Providing greater flexibility in environmental design and relaxation of strict application of the zoning ordinance in exchange for greater creativity and environmental sensitivity. 2. Recognizing the economic and cultural advantages that will accrue to the residents of a planned community. 3. Encouraging a more creative and efficient approach to the use of the land. 4. Encouraging the preservation and enhancement of desirable site characteristics, natural features, and open space. 5. Encouraging a development pattern that is consistent with land use density, transportation facilities and community facilities objectives of the Comprehensive Plan. The APC and City Council will review these criteria relative to this development. 5 PARKS AND TRAILS DEDICATION: Any parks or trails dedication due for the development shall be satisfied through a cash dedication. TREE PRESERVATION: There are no tree preservation issues with this development. WATER QUALITY/WETLANDS: Water Quality This proposed 14.1-acre commercial subdivision would be located in the City's F-watershed, which is in the northwest corner of the city. Stormwater runoff from the development eventually would enter nearby City Pond FP-1 a Class V (Nutrient Trap) waterbody that is also DNR public water wetland #19-120W. The required volume and area of water quality treatment ponds are based on the impervious proportion of proposed developments (i.e., land covered by buildings, parking lots, driveways, and walks). To meet City water quality requirements, the developer proposes to direct runoff from the site through three treatment ponds, two of which would be constructed. New Pond A in the southeast portion of the site would receive runoff from 8.8 acres of the site with 66 percent impervious cover, requiring a minimum wet-pond (treatment) volume of 1.3 acre feet. New Pond B in the northeast portion of the site would receive runoff from 3.0 acres with 76 percent impervious cover, requiring a minimum wet-pond (treatment) volume of 0.5 acre feet. An existing stormwater treatment pond to the southwest of the project has adequate extra treatment capacity and would receive runoff from the remaining portion of the site. Both constructed ponds would need a minimum 10:1 aquatic bench beginning at the normal water level. The outlet structures of the ponds would need to be consistent with City of Eagan standards. There are no wetlands issues associated with this project. ALTERNATIVES FOR COMMISSION CONSIDERATION: 1. The development shall satisfy any parks and trails dedication due with a cash dedication. This development should meet the City's water quality requirements entirely through on- site ponding. 2. This development should meet the City's water quality requirements entirely through on- site ponding a. One stormwater pond (Pond A) shall be constructed with a minimum wet-pond volume of 1.3 acre-feet and a minimum area of 0.27 acres. The other stormwater treatment pond (Pond B) shall be constructed with a minimum wet-pond volume of 0.5 acre-feet. Both ponds shall have a 10:1 aquatic bench and outlet skimmers according to City design standards. 6 Item: G -1; -Cargr* 4 Cas k F• ?e.

Existing Conditions Parks and Recreation MEMO 3. Grading Plan 4. Wetland Inventory 5. Landscape Plan 6. Tree Mitigation 7. Tree Preservation AGENDA ITEM: H-1; STEEPLECHASE OF EAGAN-TOLL BROTHERS TO: ADVISORY PARKS COMMISSION PREPARED BY: PARKS AND RECREATION STAFF ITEM OVERVIEW: Review the parks dedication, trails dedication, tree preservation, water quality and wetlands issues that pertain to the Steeplechase of Eagan development. BACKGROUND/HISTORY: The applicant is requesting approval of a Rezoning from Agriculture to PD, Planned Development, a Preliminary Subdivision (Steeplechase of Eagan) to create 102 lots and a Preliminary Planned Development to create 37 single family units and 82 townhome units for property located at 4889 Pilot Knob Road (former Diamond T Ranch site) in the SE 1/4 of Section 33. The subject property is formally the Diamond T Ranch. The property was used for horseback riding, lessons and events. The site contained commercial boarding stables. According to the applicant "over the years, the site has been extensively manipulated to accommodate horse-riding operations. Land has been leveled to accommodate parking facilities and riding trails, animal waste has historically been stockpiled in some areas and pushed over slopes and into wetlands with heavy machinery. These practices polluted and degraded wetlands, destroyed trees, and dramatically altered existing topography." A single family home is present onsite, with the intention to be sold and moved off the premise. The stables and other outbuildings are in the process of being removed. The site is heavily wooded in various locations and there is a wetland and pond present onsite. This item is scheduled for a public hearing in front of the APC on May 25, 2004 and is scheduled for the June 15, 2004 City Council meeting. This is 120 day application. The rezoning request is to rezone from Agriculture to PD, Planned Development. The intent of the Planned Development zoning district as follows: 1. Providing greater flexibility in environmental design and relaxation of strict application of the zoning ordinance in exchange for greater creativity and environmental sensitivity. 2. Recognizing the economic and cultural advantages that will accrue to the residents of a planned community. 3. Encouraging a more creative and efficient approach to the use of the land. 7 4. Encouraging the preservation and enhancement of desirable site characteristics, natural features, and open space. 5. Encouraging a development pattern that is consistent with land use density, transportation facilities and community facilities objectives of the Comprehensive Plan. The APC and City Council will review this criteria with this development. PARKS AND TRAILS DEDICATION: Parks The development area is currently serviced by a variety of parks with a wide variety of amenities within the recommended service area for a neighborhood park of 1/2 to % miles. The largest of the parks, Lebanon Hills Regional Park, abuts the south boundary of the development. The park provides a number of recreational opportunities including, hiking, mountain biking, pavilions and play structures. The Jenson Lake recreation area is located approximately 1/4 mile from the development and is accessible via trail. The development area is serviced by two existing City parks, George Ohmann and Walden Heights. Each of the parks has play structures and field space, Ohmann is a heavily used athletic facility. Both are available either by trail or low volume residential roads. The development proposes the inclusion of a village "green or commons" that would be accessible only by residents and maintained by the owners association. Because of the private nature of the space, no dedication credit could be given though the concept of a useable recreational space is encouraged. The slopes and degraded natural condition of much of the site are not conducive to additional useable park space, though there may be some opportunity for conservation easements over the more sensitive slopes and woodland. The 2004 park dedication for the development in its current configuration would have a cash equivalency of over $200,000 (SFU @ $1913, THU @ $1734) though the exact figure would be determined by the final unit count. Trails At the suggestion of staff, the development includes an 8 foot bituminous connector trail extending from the existing boulevard trail, paralleling Pilot Knob Road, to the existing County Park trail. The County trail runs under Pilot Knob to the east, via an existing tunnel, to the Jenson Lake recreation area and beyond. To the west, the trail connects into a number of internal amenities including the mountain bike area. A direct trail connection from the existing trail on the west side of Pilot Knob to the County trail has been discussed for some time. The intention has been to negate the need to cross Pilot Knob to access County and City park facilities to the east. Dakota County has indicated general acceptance of the connector trail. Issues relating to the placement of signage will be resolved with County staff. Bikes are not allowed on the County park trail. Should the connector trail be installed, the development would be given credit for the cost of the trail with any remaining dedication due paid in cash. The development plan also includes the installation of a concrete sidewalk on one side of the new residential street. While functional, credit would generally not be given for what are considered internal trails that are installed at the discretion of the developer. 8 TREE PRESERVATION: A tree inventory submitted with this application indicates that there are seven-hundred sixty- nine (769) significant trees in the inventory. Individual tree size and species break down is as follows: Detached Units Attached Units Total Species Count % of Total Count % of Total Count % of Total Oak 79 49% 416 69% 495 64% Boxelder 49 30% 29 5% 78 10% B Cherry 10 6% 96 16% 106 14% Elm 5 3% 23 4% 28 4% The balance of the tree inventory is comprised of cottonwood, aspen, crabapple, pine, and willow. The development as proposed will result in the removal of a total of six-hundred twenty-four (624) significant trees (81.1 % of the total). According to the City of Eagan Tree Preservation Ordinance allowable tree removal for this development proposal will be calculated based upon the specific use of different parts of the site. The northern third of the site will have single-family detached homes; allowable removal for this area is set at 40%. The southern two-thirds of the site will have single-family attached (multi-family residences); allowable removal for this area is set at 47.5%. The table below shows proposed tree removals. Detached Units Attached Units Allowable Removal 40% 47.5% Existing Trees 163 606 Proposed Removal 148 (90.8%) 476 (78.5%) Required Mitigation 186 504 (Category B trees) With a proposed removal greater than the allowable amount, there is a required tree mitigation for this proposal calculated at six-hundred ninety (690) Category B trees. The applicant has submitted a Tree Mitigation Plan that indicates the fulfillment of required tree mitigation through the installation of 405 Category B trees and 68 Category A trees, for a total equivalent of 541 Category B trees. At the writing of this report the Tree Mitigation Plan does not satisfy city requirements. There is a balance of 149 required Category B trees that will need to be fulfilled through additional plant installation or a cash payment of $44,700.00. Dakota County Parks Department has provided comments as follows: 1. The Park would like "shared trees on the park boundary to be removed only with park concurrence. 2. The Park would also like to "require predominately native type woody vegetation plantings between road edge and property line". 9 City staff agrees that there should be some, communication between the applicant and the county as to which trees will be removed, and the potential reduced removal in these "shared" areas. Also, the use of more "native" plant stock should be considered on all sites, with the overall goal of matching new plant requirements to existing site conditions. WATER QUALITY/WETLANDS: Water Quality This proposed 38.0-acre subdivision is located primarily in the upper portion of the City's LP I -Watershed, which flows west to east through numerous Class I, III, and IV waterbodies in Dakota County's Lebanon Hills Regional Park. Immediately downstream of the parcel and in the county park is Jensen Lake, a state public water and a Class II Indirect Contact Recreation waterbody, according to the City's Water Quality Management WQMP (WQMP). The northwesterly quarter of the parcel is in the BLP-Watershed and drains through Walden Heights Park to Thomas Lake, which is a Class I Direct Contact Recreation waterbody, according to the WQMP. The developer proposes to address City on-site stonnwater quality requirements primarily by treating runoff via a series of six ponds and wetlands, four ponds of which would be new. A 2.4-acre area (Drainage Area 1) on the north side of the parcel is proposed to drain to a new, low-lying "dry" pond (Pond 1). Drainage Area 2 (16.4 acres) would receive stormwater from Drainage Area 1 and from 13.7 acres of the development and drain to new Pond 2. Drainage Area 3 would receive stormwater from Drainage Areas 1 and 2 and from 1.9 acres of the development and drain to existing stormwater pond (City Pond LP-56), which is a Class IV Wildlife Habitat waterbody, according to the WQMP. Drainage Area 7 (5.8 acres), west of the flooded wetland, is proposed to drain to a new pond (Pond 7) in the southwest portion of the parcel; Drainage Area 8 (4.1 acres), east of the flooded wetland, is proposed to drain to a new pond (Pond 8) near Pond 7. Both Ponds 7 and 8 would overflow to Pond 4, which includes natural wetland and proposed new wetland area as replacement for wetland fill impacts to the site. Pond 4 would drain southerly to the county park on a greater than 100- year frequency or as desired with a control structure. The 3.3-acre area of the parcel that is proposed to drain off site without any treatment would be subject to a cash dedication. Minimum requirements for volume and area of water quality treatment ponds are based on the impervious proportion of proposed developments (i.e., land covered by buildings, parking lots, driveways, and walks). The impervious proportions of the drainage areas of the proposed subdivision will be used to calculate minimum volume requirements for respective treatment ponds. Wetlands The wetland delineation report for the project site (GME Consultants, Inc.; Project No. 10745) identifies five wetland basins subject to the City of Eagan's jurisdiction according to the Minnesota Wetland Conservation Act (WCA). Any proposals to drain, fill, or excavate these wetlands need to meet all provisions of WCA laws and rules. The report identifies the five wetlands as Basins A through E. Basin A, mentioned previously as City Pond LP-56, is considered a Type 4 wetland, under the classification system of the Fish and Wildlife Service. Type 4 wetlands are inland deep fresh marshes in which the soils are usually covered with six inches to three feet or more of water during the growing season. Vegetation may include cattails, reeds, and bulrushes. In this case, broad-leaf deciduous trees are in a semi-permanent flooded basin. 10 Basin B is known as City Pond LP-7.2, which is also a Class IV Wildlife Habitat waterbody according to the WQMP. The delineation report identifies this wetland as a Type 3 wetland. Type 3 wetlands are inland shallow fresh marshes that are permanently inundated with six or more inches of water during the growing season. Vegetation includes grasses, bulrushes, and various other marsh plant such as cattails, arrowheads, and smartweeds. Basin C is identified as a flooded depression area that historically held three small wetlands. Together, they are considered Type 3 wetlands, according to the delineation report. The WQMP also classifies Basin C as a Class IV Wildlife Habitat waterbody. Basin D, located near the north central portion of the site, is also considered a Type 3 wetland by the delineation report. Basin E, located near the east central portion of the site, is not typified by the delineation report. However, it likely is a Type 3 wetland. There is significant evidence that all five wetlands have suffered varying degrees of degradation and varying amounts of fill by previous landowners. Degradation appears to be due to combined affects of horse manure leachate, horse trampling, and stormwater flooding. The developer proposes to impact wetlands on the site by selective filling and to replace those impacts by creating new wetland areas. According to state law, before the City can approve such wetland impacts and replacement, the developer must document to the City's satisfaction specific attempts made in priority order to avoid, minimize, rectify, and reduce the impacts. Once all of those principles have been met, the City can decide on a wetland replacement and monitoring plan, which the developer filed with the City on May 5, 2004. After the 30-day public comment period on the plan ends June 9, 2004, the City Council is scheduled to make a decision on the replacement and monitoring plan June 15, 2004. Due to the complexity of the wetland-related issues of this development, the City will be assembling the Wetland Technical Evaluation Panel (WTEP) before the City's decision date. The WTEP is comprised of staff with technical wetland expertise from the Dakota County Soil and Water Conservation District, the Board of Water and Soil Resources, and the City of Eagan. The purpose of the WTEP is to provide the City technically accurate and thoughtful recommendations on the project. The City must consider WTEP recommendations in its decision making process. According to the wetland replacement plan, the developer proposes to fill entirely Basins B and D (25,457 square feet) and replace those impacts by creating 30,415 square feet of new wetland area in the area of Basin C and 36,136 square feet of public value credits as' stormwater treatment ponds and wetland buffers. The proposed amounts of replacement meet the minimum 2:1 standards of the WCA rules. NOTE: While the Commission is considering this development proposal tonight, it will have another meeting June 14, which is the day before the scheduled decision date of the wetland replacement and monitoring plan by the City Council. The Commission may want to consider the forthcoming findings and conclusions of the WTEP's review in advance of fully committing its recommendations on the plan to the Council. 11 ANIMAL WASTE Historical use of the land as a commercial horse riding and boarding stable has significantly impacted portions of the site. Of primary concern to water quality are large deposits of manure which have been spread near slopes that ultimately drain to Basin C. Much of this manure has been in place for a number of years, but its stability and current nutrient leachate potential is unknown. Historical files on the parcel indicate dialogue and concerns expressed by residents and the City to the former landowner with involvement by the Minnesota Pollution Control Agency (MPCA). The City's concerns related to violation of the Conditional Use Permit for the horse stable business. The MPCA's concerns related to manure leachate and direct nutrient runoff into the wetland areas causing high fecal coliform counts. The MPCA also was concerned about animal feedlot operations.

Mark Filipi, and Elizabeth Perry. Staff present included Jeff Asfahl, Superintendent of Recreation; Paul Olson, Parks Superintendent; Cathy Bolduc, Program and Events Supervisor; Paula Nowariak, Recreation Supervisor, Colleen Callahan, Youth Development Coordinator, Beth Wielde, Research and Special Projects, Gregg Hove, City Forester, Eric Macbeth, Water Resources Coordinator, Shawna Skovbroten, Youth Development, Lisa Piccolino, Teen Development, and Cherryl Mesko, Administrative Coordinator/ Recording Secretary. UNUMBIDWOM N. Mark Filipi moved, Dorothy Peterson seconded to approve the agenda, amended to pull `Revised Tree Ordinance." All attending members voted to approve the agenda as amended. Member Perry moved, Member Danner seconded, with all present members voting to approve the minutes of March 15, 2004, with one amendment, adding "Joe Bari" to the attendees. g7jo A group of teens, with spokesman Alex Kanwischer from Eagan High School, expressed concern that bikes are not allowed in Eagan Skate Park. They disagree with the policy, and want to work with City Council to find out how to take action on the issue. They argue that there is less damage with bikes that skateboards in the parks. They have been to the dirt bike parks, but note that they are unable to do tricks on a dirt course. The youth suggested sharing the Skate Park with the skateboarders. They note how they shovel snow off the ramps in the winter for their use, and that a parent has plowed the parking lot so they could practice their sport. Chair Davis noted that the APrC had seen the petition prior to the meeting, and that they were hoping the youth would appear before the commission. He noted how changing the use of a facility often takes time. He said the Skate Park had been designed for skateboards, and there would need to be investigation into different use. He informed the bikers that a new bike or skate park had been considered in the CIP for 2005, and during the CIP study next year the APrC will look to the youth for help. He told the youth that they have done a great service by bringing the petition forward, showing community interest in a bike park. He said the process would limp along this summer, the dirt parks will still be available, but the future might bring new opportunity. Member Peterson suggested meeting with staff to determine what the youth would like in a dirtbike park, location, and youth involvement in helping to plan the layout. Peterson said the APrC could work with City Council to determine if something could happen through the CIP. Member Danner asked the group if they had used the dirt bike park. Kanwischer said they had, but it doesn't lend itself to the tricks a biker can do on a paved facility. He said the youth had been using the Skate Park, but would rather work within the system to get something developed for bikers. Member Peterson thanked the group for coming. S i 4 J P E I i ~ l J EN AT t AND DEPART i I PPw Recreation Superintendent Asfahl reviewed activities of the Recreation Division, including: • Eagan Fun Run and Duckie Dash • Basketball and Volleyball seasons have begun • Adapted tumbling and the commencement of • Softball schedules are complete adapted track • Spring session of preschool has 361 children • Golf lessons beginning signed up • Senior involvement with the Red Hat Society Advisory Parks Commission Minutes of the Regular Meeting of April 19, 2004 Page 2 Parks Superintendent Paul Olson reviewed activities of the Parks Division, including: • Work is wrapping up on the Thomas Lake • No tree sale in 2004 Pavilion • Arbor Day events • Vandalism issues • Contact information for groups wanting to • Responses to playground RFPs participate in park clean-up projects. • DNR grant applications submitted on March 31 • Disc Golf course installation • Preparation of soccer and ball fields Member Bari asked Olson what happened when vandals are caught. Olson said generally retribution- the department recently got an $800 check for damage to a slide. Member Danner asked about the disc golf course, whether anyone can use it. Olson said yes, noting the discs used in disc golf are slightly different than those used for regular Frisbee; they are weighted differently. People can purchase them in area stores. RECREATION UPDATE- PAULA NOWARIAK Nowariak provided statistics and information about winter programs, reviewing staffing levels (49 staff and 3 program assistants for 45 hours per week), buildings used, the difference between Class A and Class B sites, and attendance. She cited attendance at almost 17,000 visitors for the 2003-2004 winter season. She reviewed the season at Trapp Farm Park Sliding Hill, noting the $2 fee and punch car offer has not deterred visitors from coming. The sliding hill was open 28 days in a row. Group reservations were offered. Attendance was up from 2003, with 4,047 visitors. Family trips were offered, going to see the Minnesota Wild play at the Excel Energy Center, the Timberwolves play at the Target Center, and to see Sesame Street Live. Special events included Halloween events and Don't Break the Ice Fest. Over 80 applications were received for summer staffing; limited openings remained. Nowariak said there were 26 returning staff. Member Peterson asked if Ridgecliffe Park is as busy as it has been in past years, and suggested "talking up" winter sites. RECREATION UPDATE - COLLEEN CALLAHAN Callahan introduced the Youth Development and Teen Development staff. She said the division is looking at collaborations and working with apartment complexes and other cities on programming and overall communications, including groups such as EAA and EAH. She introduced her staff members by commenting that recreation offers an opportunity to play together. Shawna Skovbroten, Youth Development staff, discussed after school programs, the Pilot Knob after- school program, shared the participation numbers for the quarter, and future growth, including the desire to add 2 new sites. Summer plans include Wescott Commons. Callahan said one of the biggest challenges for all the programs is funding. Lisa Piccolino discussed her eight month involvement with Teen Development, noting the Teen Center has increased participation from 549 participants to 641. She said the teen dances are becoming very popular, a recent dance had 82 attendees. High school dances are starting in April. Upcoming summer events, including Wheel Jam, What's Kickin', Battle of the Bands, and the Film Festival, were highlighted. Member Peterson asked if there was success with CDBG funds. Callahan said they are involved each year with the review. They will continue to stay "plugged in." Member Danner asked whether there are more kids during the day or evening. Callahan said it is very unpredictable. Danner asked if hours will expand in the summer. Callahan said yes, to some degree they would. Danner asked who monitors the Teen Center during it's open hours. Callahan said it is Lisa Piccolino, college students, high school students. Advisory Parks Commission Minutes of the Regular Meeting of April 19, 2004 Page 3 RECREATION UPDATE CATHY BOLDUC Recreation Supervisor Bolduc provided updates on winter programming, including adapted basketball, with 33 participants, Rink Rats youth hockey with 46 participants, Don't Break the Ice Fest with 277 attendees, and Breakfast with Santa, with 113 participants. Bolduc described senior activities, noting how very active and involved they are. She discussed the Lone Oak Room, which has become a hub of senior activity, and accomplishments of the year such as activity of the Senior Advisory Board, acquiring a tax exempt number and bank account, a successful membership drive, and the start of evening and weekend programs. She detailed some of the recent and upcoming spring activities, such as Breakfast with the Easter Bunny, Eagan Fun Run, Evenings in Central Park, SORR Corporate Challenge, adapted programs, nature/ environmental programs, babysitting and latch key clinics, and senior activities. She also described sport instruction and skill development for golf, tennis, and in-line skating. COM AGE NN Elizabeth Perry moved, N. Mark Filipi seconded with all present members voting to approve the Consent Agenda, except the Revised Tree Ordinance that was pulled from the agenda. EVERGREEN ENCLAVE - EPIC DEVELOPMENT Planner Sheila Cartney provided background into the Evergreen Enclave development proposed by EPIC Development. Paul Olson described the proposed trail system and the donation of an Outlot A and a cash dedication. City Forester Hove reviewed the tree preservation issues association with this development. He showed an aerial photo of the site and reviewed the site plan. He shared photos of the site from several vantage points. He reviewed the forestry inventory, and alternatives for the APrC to consider. He noted that the developer did a great job with the site. Member Danner asked about the slope in relation to the roadways, whether it slopes downward, which was affirmed. Water Resources Coordinator Eric Macbeth said the original plan resulted in a significant review. The extremely steep topography of the site would have made it nearly impossible to meet water quality requirements by constructing a retention area and trenching stormwater pipes without significant impacts to the site and very high risks of erosion. In the resubmitted plan, there is no ponding on the site. Instead, a series of rainwater gardens is proposed, which eliminates the need for ponding. Macbeth said this situation is unique. Member Peterson asked what the rainwater gardens would look like. Macbeth deferred to the developer to speak to that. Rich Raggatz of EPIC Development said this is a special site, with 2 private drives. He detailed the rainwater gardens, the conservation easement in the center of the site, the donation of the outlot, and the retaining wall that will allow additional tree preservation. Chair Davis said he appreciates all the work EPIC has done with the site, and asked the developer to describe the rainwater gardens. Raggatzsaid they would resemble low grassy areas. Randy Hedlund, the civil engineer for the developer, said it was a challenging site, and looked and a `no stormwater pond' scenario. He said there are 10 sub-watersheds on the property, the largest being 1/3 acre. He said the City of Maplewood has a detail plate that shows generally what the rainwater garden would look like. He said there would be a garden between each lot, and each garden would consist of a trench filled partially with clear rock and then successively covered with fabric and topsoil, and finally planted. The proposal shows that each rainwater garden would be designed specifically with each house on the site. The idea is to recharge groundwater and eliminate piping. Advisory Parks Commission Minutes of the Regular Meeting of April 19, 2004 Page 4 Chair Davis asked how, after initial gardening, there will be protection against erosion. Hedlund said there are very strict grading and erosion specifications. Member Danner asked who would be responsible for the rain gardens. Hedlund said most likely the association would be responsible, and it is important to make sure the gardens continue to function. Chair Davis asked how long the rainwater gardens have been used in other communities. Hedlund said about 5 years, noting that Maplewood has been actively, and very successfully, using them for a period of time. Member Perry suggested looking at including the rainwater gardens in the conservation easement so they will be kept in place. Chair Davis said he appreciates all the work EPIC has done with the site, and to please describe the water gardens. Raggus said they resemble low grassy areas. Randy Hedlund, also from EPIC, said it was a challenging site, and looked at a `no storm water' scenario. He said there are 10 sub-watersheds on the property, the largest being 1/3 acre. He said the City of Maplewood has a detail plate that demonstrates what the rainwater garden might look like. He said there is a garden on each lot line, and each garden is made up of 1-1.5"of clear river rock, fabric, topsoil and plantings. The proposal indicates the rainwater garden will be designed with each house on the site. The idea is a new philosophy of re-charging ground water and eliminating piping. Chair Davis asked how, after initial gardening, there will be protection against erosion. Hedlund said there are very strict grading and erosion specifications. Member Danner asked who would be responsible for the rain gardens. Hedlund said that it would most likely be the association, and it is important to make sure the gardens continue as a functioning system. Chair Davis asked how long they have been used in other communities. Hedlund said about 5 years, noting Maplewood has been actively, and very successfully, using them for a period of time. Member Perry suggested looking at including water gardens in the conservation easement so it is not changed. Member Peterson moved, Member Bari seconded with all present members voting to make the following recommendations to the City Council relative to the Evergreen Enclave development. 1. The Development shall be responsible for a cash trails dedication. 2. The Development shall be responsible for a cash parks dedication. 3. Recommend the acceptance of the donation of Outlot A to the City for park purposes. 4. To require that Tree Protective measures (i.e. orange colored silt fence or a 4' polyethylene laminate safety netting) be installed at the Drip Line or at the perimeter of the Critical Root Zone, whichever is greater, of significant trees/ woodlands to be preserved. 5. To require that the applicant contact the City Forestry Division and set up a pre-construction site inspection at least five days prior to the issuance of the grading permit to ensure compliance with the approved Tree Preservation Plan and placement of the Tree Protection Fencing. 6. To meet City water quality requirements, the development should create a series of "rainwater gardens" or "infiltration basins" to collect and infiltrate stormwater runoff from both streets. Technical designs and details of such structures should be acceptable to and approved by Eagan Water Resources and Engineering staff. 7. A cash dedication in lieu of ponding should be applied to impervious area of the development that contributes stormwater that is not captured in the "rainwater gardens" or "infiltration basins." DM SYCAMORE PLACE - WETLAND REPLACEMENT PLAN Eric Macbeth provided some history of the development review; On January 15, 2004, the APrC adopted recommendations to Council regarding the development, with the exception of the wetland issue. The wetlands issue was postponed due to conflicts found in wetland delineation reports. On February 24, Eagan's Wetland Technical Evaluation Panel (WTEP) reviewed the conflicting wetland reports, recommending the City require the developer to provide additional information from historic and current sources that supports the claim of fewer wetlands, smaller sizes of wetlands, and different types of wetlands compared to the findings of the most recent delineation report. Because of disparities in the reports and the timing of the issues needing to be resolved, the City told the developer it would deny the exemption they requested without additional information by March 14, 2004. The developer voluntarily withdrew the exemption application on March 4, 2004, and submitted a wetland replacement plan application on April 14, 2004. Advisory Parks Commission Minutes of the Regular Meeting of April 19, 2004 Page 5 Macbeth exhibited the most recent delineation. He showed the 1 acre of wetland and the proposal to replace it with a banking site outside of Eagan. There was no proposal for on-site replacement, nor a proposal for replacement within Eagan. Macbeth stated the wetlands on site are not considered high-quality wetlands based on water quality standards. He said the developer is, however, required to show alternatives to avoid impacting them. He said the area of Eagan is low; to get stormwater to flow off-site, fill will be required. He then explained wetland banking. He said the developer proposes to withdraw up to 2.48 acres of credits from the state wetland bank, which is an option that state wetland conservation rules allow. Chair Davis asked how the wetlands are being protected with the community losing wetlands. Macbeth said there is a priority order of siting- there is an attempt to create a replacement as close as possible to the original impacted area. Chair Davis asked if there was room to make some adjustments to the plan as proposed; Member Peterson recalled the previous approval ofstormwater ponding on site. Macbeth said stormwater pond remains in the plan and meets City requirements. Chair Davis asked if the person banking the wetlands needs to own both the delineated wetland and the banking site. Macbeth said no, they would only need to have an agreement with the owner of the replacement site. Chair Davis asked if the replacement could be made within the City. Macbeth said possibly. Member Filipi asked why the wetland replacement/ delineation increased from the original report. Macbeth said the difference related to the differing consultants' judgments of the wetlands on the site. The first survey, which indicated less wetland coverage, was done on April 25, 2002, and the second survey, which indicated more wetland coverage, was done on April 24/25, 2003. Macbeth said second survey provided support for the climatological conditions to be considered "normal," whereas the first survey could be considered to have taken place during "dry" conditions. Macbeth said the Advisory Planning Commission would be reviewing the proposed wetland replacement plan on April 27, and the City Council would consider it for a decision on May 18. Comments on the wetland replacement plan need to be received by the City by May 17. Subsequently the Advisory Planning Commission could review the plan on May 25, and City Council could make a decision on June 1 or 15. He noted City Council makes decisions on proposed wetland replacement plans, but staff administers the details for implementation , monitoreing, and guaranteeing final acceptable completion. Member Filipi asked for clarifications about questions from the public about flooding and traffic. Macbeth said these should be addressed by the Advisory Planning Commission or the City Council. Filipi specified that the only question that the Advisory Parks Commission should be addressing in regards to the Sycamore Place development relates to the wetland issues. A question from the audience arose about how the easement for the Broadmoor subdivision in Inver Grove Heights was acquired. Macbeth said that segment remains and meets City requirements. A representative from EPIC Development, Rich Raggatz, said the site was challenging. He shared photographs of the water drainage from the Weston Hills area west of the site. Chair Davis noticed the water coming from the street, and asked if the street floods, whether there's enough grade in the pipe to take it away from the site. Rich said the elevation of the site would need to be raised. Member Peterson asked where else in Eagan EPIC had looked for areas to replace the wetland. Rich said they have not come across anything to date. Chair Davis asked how recent the search was. Rich said nothing had been done recently. EPIC's wetland consultant Ron Peterson said there are only 2 other mitigation sites in the county, and neither are in Eagan. Macbeth said the Advisory Planning Commission would be reviewing the proposal on April 27, and the City Council would review it on May 18. Comments regarding wetland replacement need to be received by May 17. Subsequent plans would be reviewed by the Advisory Planning Commission on May 25, and City Council on June 1 or 15. He noted City Council handles wetland replacement plans, but staff would require that this work be monitored and guaranteed for completion. Advisory Parks Commission Minutes of the Regular Meeting of April 19, 2004 Page 6 Member Filipi asked about questions from the public about flooding and traffic. Macbeth said these should be addressed by the Advisory Planning Commission or the City Council. Filipi specified that the only question that the Advisory Parks Commission should be addressing in regards to the Sycamore Place development are the wetland issues. A question arose about how the easement for Broadmoor was acquired. Macbeth said it was not land ownership. Assistant City Engineer John Gorder said it was property condemnation that the City of Inver Grove Heights went through the process for sanitary sewer and drinking water. A representative from EPIC development, Rich, said the site was challenging. He shared photographs of the water drainage from the Western Hill site. Chair Davis noticed the water coming from the street, and asked if the street floods, whether there's enough grade in the pipe to take it away from the site. Rich said the elevation of the site would need to be raised. Member Peterson asked where else in Eagan EPIC had looked for areas to replace the wetland. Rich said they have not come across anything to date. Chair Davis asked how recent the search was. Rich said nothing had been done recently. Wetland Consultant Ron Peterson said there are only 2 other mitigation sites; Burnsville and Cannon Valley. He said priority qualification is for on-site mitigation (same watershed), same major watershed, or within the same county. He said the Replacement Plan has been built and would be monitored this summer. He said if the City desired, it could `condition' the mitigation. Craig Murray, 4812 Weston Hills Drive said it is a difficult site, and noted it was a broad interest in having it developed properly. He said it is hard to differentiate the wetland issues from the other site issues such as storm drainage. He said fewer lots and lessening wetland impact would mitigate the overall impact. He asked that another lot layout be considered. He asked if the presentation reflected the actual, accurate amount of wetlands. Chair Davis asked what the difference in the wetland acreage was. Peterson replied that the current figure is based on the beginning of the growing season. Macbeth said the 1.24 acre figure includes fill and evacuation. He expressed comfort with the 2003 report. Tom King, also of Weston Hills Drive, expressed his desire that the APrC vote `no,' expressing concern about tree removal, replacing wetlands outside of Eagan, and the figure shown at the January 15 meeting of 40,000 cubic yards of fill. He claimed that was the equivalent of 3,333 dump trucks of dirt. He expressed concern about traffic on the site and wear and tear on the roads. He expressed the desire to keep the wetlands within Eagan, and create fewer lots. Jeanne Park, 4816 Weston Hills Drive noted that rainfall had flooded out a functioning wetland. Bonnie Sogge, 4830 Sycamore Court shared the topography of the lot, currently 952', and the development would raise it to 954.5'. She encourages less development on the site. Bev Hannon, 4804 Weston Hills Drive, said she would like to see wetland mitigation on the site rather than removal of the wetland. Tom Nelson, 4204 Weston Hills Drive said his household enjoys the wetland area, it is pristine and should be maintained. Donna Tjornhom, 4820 Weston Hills Drive showed a picture taken in April showing the drainage of the site. She said she noted wetlands being minimized on the site, and expressed concern for fill on the site. Her concerns focused on the drainage issue. Member Danner asked if someone could address the questions of fill and water flow. Tom King noted that the grade was proposed to be raised 6'in some places. Assistant City Engineer John Gorder said a pipe would be constructed at a flat grade, with a stormwater pond it would fill. He said City standards are based on a 100 year storm event and the proposed ponding meets this standard. Chair Davis asked if there had been discussion of decreasing the number of lots to preserve the wetlands. Rich Raggatz of EPIC Development said any development will raise the land, that the other way to handle water would be a pumping station, which the City doesn't want. Advisory Parks Commission Minutes of the Regular Meeting of April 19, 2004 Page 7 Tom King asked whether only developing a portion of the property would result in greater preservation. Superintendent of Parks Olson reminded the APrC that they had previously recommended approval of the development, that the APrC's responsibility at this time is to look only at the proposed wetland replacement plan. Donna Tjornhom expressed her opinion that the proposal needs to be dismissed and the developer needs to start over. Chair Davis noted that the proposal showed the same driveways, the same lots, the only difference is how the developer is dealing with the. wetlands. Member Perry noted the plan had not changed, that the wetland replacement issue is the only one on the table at this time. Rich Raggatz from EPIC Development noted that fill won't change the problem. Member Filipi moved to recommend denial of the proposal regarding the wetland replacement issue, citing a desire for the developer to make a better effort to keep the replacement wetlands in Eagan. Dorothy Peterson seconded, with all present members voting unanimously. Chair Davis commented to the developer that these functioning wetlands should be left intact as much as possible. Member Danner expressed a desire to "do this right." Member Perry agreed with Member Filipi, that they would like the wetland issue explored further. There was no new business for the Advisory Parks Commission to discuss under this agenda item. ESQ There were no Water Resources issues presented to the Advisory Parks Commission under this agenda item. R W, , -0 Nl3 RE~ TS The Advisory Parks Commission received a copy of the Parks and Recreation Annual Report. There was no action required under this item. A meeting of the Natural Resources Subcommittee will be held May 5, 5:30 pm at the maintenance facility. The group will discuss the Tree Preservation Ordinance. Member Peterson mentioned the possibility of recognizing the efforts of Friends of the Farm members Don Holz and Maynard Ohm. With no further business to conduct Dorothy Peterson moved, Mark Filipi seconded with all members voting in favor to adjourn the meeting. The meeting was adjourned at 8:10 p.m. Secretary Date Minutes drafted by Beth Wielde
