Recognition of Sharon Holbeck MEMO city of eagan TO: ADVISORY PARKS COMMISSION FROM: KEN VRAA, DIRECTOR OF PARKS AND RECREATION DATE: JULY 16,1998 SUBJECT: JULY 20 COMMISSION MEETING The Commission meeting will be preceded by a brief tour of projects currently underway. We will meet at the east entrance of City Hall and begin the tour at 6:00pm. As time permits, we have scheduled to see the new dosing station for Fish Lake, followed by a visit to Lexington- Diffley Athletic fields.where the new service buildings are being constructed. The Commission will return to the Civic Arena site to see the progress being made on the new arena addition and the grading now underway for the Aquatic Facility. After the Call to Order and Pledge of Allegiance, a representative from the Minnesota Recreation and Park Association (MRPA) will present an Honorable Mention Award for the Blackhawk Park building design and construction. Approval of the May 18 and June 15 minutes are in order, followed by Visitors to be Heard and Department Happenings. There are two items on the consent agenda. A single motion to approve is in order unless there is a need to pull an item for further discussion. There are two development items with a memo for each. Item 2 relates to the property generally referred to as the "Bieter Property". The Commission in May of 1997 last reviewed development on this property. The Commission's action was to recommend a cash park dedication with trails and sidewalks to be installed along the extension of Johnny Cake Ridge Road and the street connection to the school located to the east. Attached to the memo is the Commission's action from May of 1997. OLD BUSINESS Since the last Commission meeting, staff has met with the architect for Advent United Methodist Church to review the issues that need further engineering work and plan refinement. The item appears on the agenda in anticipation that additional information may be available by the Commission meeting for further review. Later on the agenda is a request to schedule an Acquisition/Development subcommittee meeting to review the design issues related to this project in greater detail. Skyline Displays contacted staff after the last Commission meeting and indicated that they were again trying to move ahead with a revised concept plan for "Discovery" Park. Several of the oak trees that were planned to be saved have succumbed to the storm of May 30'. Consequently, the planner is revisiting that area to see what implications to the design the tree loss might have. As of this writing, staff has yet to see a revised plan. NEW BUSINESS: The single item under new business for consideration is a proposal from Mr. Don Grant, a long time resident of Eagan, who lives west of LeMay Lake and north of Moonshine Park. Mr. Grant is proposing the City acquire his property for park purposes (see attached letter) to be incorporated into Moonshine Park and any further expansion to the park around the south end of the lake. Parks Planner C. J. Lilly has prepared an analysis of the area for Commission review. PARKS DEVELOPMENT: The Commission will have an opportunity to see several of the construction projects that are under way. Staff will also update the Commission on the progress that has occurred with the construction of Walden Heights Park. WATER RESOURCES UPDATE: Water Resources Coordinator Rich Brasch will review the results of the educational survey taken several weeks ago. Rich has had an opportunity to digest some of the information and will discuss the implications with the commission. OTHER BUSINESS AND REPORTS: There are several items to be reviewed with the Commission including the impact of the storms in May, input from the Commission is solicited regarding the 1999 proposed budget, sub- committee updates should be provided, a brief pool update, setting of sub-committee meetings and the appointment to a new committee the City Council has recently authorized to help determine how additional trees can be made available to the community to replace those that were lost in the storms. If members of the Commission are unable to attend, please let us know by calling 681-4661. Respectfully submitted, Ken Vraa Director of parks Recreation. DEPARTMENT HAPPENINGS FOR JULY 1998 1. During the first three days of summer programs, 1208 children participated. During the first full week, 2494 youth could be found in department activities. Youth Development activity participants at Wescott, Quarry and Rahn are not included in this data. 2. Evening in the Park concerts have drawn typical crowds of 150-250 people. The high water in Schwanz Lake has impacted the amphitheater; events have been held in the pavilion. To date that area has handled the crowd satisfactorily; we shall see when the Teddy Bear Band comes to town on August 5. 3. Eagan Athletic Association travel baseball and softball programs held successful tournaments on City facilities in June. Rain was a factor on all three-week ends. Parks Maintenance reports being down to one bag of diamond dry when the final game was played! EAA tournament organizers sang praises of the work the Department's ball field attendants were able to perform. 4. The new in-line hockey camp and on ice shooting and stick handling schools are in full swing. Mike Gibbons, the varsity hockey coach at Eastview High School is the lead instructor. This activity is an example of the Department being an enabler for a program to be held, versus a program initiated, planned and directed by Department staff. 5. Tennis continues of the upswing in Eagan. Virtually all youth classes for the summer have been filled. The league and camps are challenging young players to strive for the next level. 6. The Holz Farm Hog Roast was fun for those who attended; however, higher attendance is needed. Friends of the Farm will be challenged as to whether the July 4`s weekend is the best the summer has to offer. 7. Would you believe that adult softball will, at the date of the Commission meeting, have only two weeks remaining? Never fear, fall softball information will be sent out by July 10s'. 8. Staff are in the interview process to fill the Sports Program Supervisor position. It is hoped that the position will be filled by August 1. 9. The Somali Community will begin using the Quarry Park shelter on the weekend of July 11/12. Time frames, responsibilities and the duration of the agreement have been settled and the group will now begin its work with the Somali youth. 10. Staff will be interviewing a potential undergraduate Recreation intern from the University of Minnesota, Duluth. The Department has not previously hosted an intern from that school. It will be interesting to learn of UMD's program. The internship would be for the fall term. 11. The Department has provided interpreters for Evening in the Park events and for two sessions of tennis lessons. 12. Staff are in the process of identifying facility skip dates from schools in order to allocate field space for Eagan Athletic Association soccer and football. The numbers of participants appears to have reached a plateau and field space will be sufficient. 13. Instructional programs and Summer in the Park end on July 25. Starting the week of July 27, recreation moves into a "camp format". Science, Nature, Drama, Mystery, Kraft and Day Camps are just a sample of what's being offered. Most camps are filled to capacity. 14. Field trips have been popular this summer. The youth of Eagan have ventured to Skateville, Mann Theaters, Bowling, Circus Pizza, Dakota Hills Middle School pool, Crystal Caves, Bunker Hills Wave Pool, Valleyfair and Diamond T so far this summer. Remaining trips include a Twin's Game, Beaver Mountain and the Picnic in the Park. 15. A craft specialist has been visiting Summer in the Park and Wagonful O'Fun sites this summer. Cara Doring is an art specialist who teaches at Pinewood Community School in Eagan during the school year. Cara has brought a new twist to the program. Our focus has been on recyclable art projects this summer. Cara will also be leading a few sections of Kraft Camp. 16. Electrical and plumbing work was completed on the Fish Lake dosing station by Utilities Division staff and the dosing station started trial operation on Thursday, July 16. Water resources staff have been working with the University of Minnesota to collect pre-treatment baseline information to measure effectiveness and impacts of operation of the system. The next phase of monitoring will begin within the next several weeks. 17. The Minnesota legislature and the MN Department of Natural Resources have awarded the City of Eagan of $10,000 grant through the Conservation Partners Grant Program to carry out an experimental iron treatment of Heine Pond to control the exotic macrophyte curly leaf pondweed. The iron treatment is scheduled for this fall, and follow-up monitoring will determine its effectiveness. 18. Water Resources Coordinator Brasch appeared before the Legislative Committee on Minnesota Resources last week to testify in favor of a grant application by Dakota County to expand the citizen-based wetland health monitoring program. The Advisory Parks Commission wrote a letter in support of the grant proposal this spring. 19. Tree Trust has completed the construction of a new exit ramp from the Holz Farm barn as required by building code. An upgrade of the electrical system in the barn is being researched. 20. Over 325 tickets were sold for the Holz Farm Hog Roast on July 5. The Friends of the Farm realized a profit of over $1,200. 21. Free wood chips generated from storm debris are available at the end of Nicols Road, just northeast of the intersection of Highways 13 and 77. Residents are asked to take from the pile in the cul-de-sac. 22. It is now safe to trim oak trees. 23. City crews have started the installation of the new playground structure at Woodhaven Park. New structures will be installed later in the year at Evergreen and Highview Parks. 24. Plans for the installation of lighting on the Little Goat ballfield are nearing completion. Staff is intending to have the project completed this fall. 25. The renovation of the tennis courts at Rahn Park has been put on hold as a result of the project backlog created by the storm. The renovation of the exterior and roof of the Rahn building will be completed as scheduled. 26. The Dakota County Sentence To Service crew will be assisting with the mulching of trees and planting beds the week of July 20. 27. Construction of the new service building at Lexington/Diffley continues. Completion is still expected by early September. Staff has assisted with the implementation of several change orders to minimize additional costs. G:Typing pool/Department Happenings July 1998 f.

NOREEN BACKGROUND Mr. James Noreen is requesting preliminary subdivision approval to allow the creation of a three lot single family residential subdivision located north of Cliff Road and east of Lexington Avenue (directly north of Holland Lake). In conjunction with the requested preliminary subdivision, the applicant has also requested a rezoning of the subject property from an A,Agriculture to an R-1, Residential Single Family zoning designation. The subject 6.4 acre property is heavily wooded and slopes gently to the south. The site also lies within the shoreland overlay district of Holland Lake (a natural environment lake). All lots within the subdivision are proposed to be served by private sewer and water (i.e. septic systems and wells). This item is scheduled for consideration at the forthcoming July 28'' Advisory Planning Commission meeting. PARKS/TRAILS DEDICATION This development shall be responsible for a cash parks dedication and a cash trails dedication for the newly created lots. TREE PRESERVATION Both lots 1 and 3 of this site contain a variety of significant hardwood deciduous trees. Staff has had discussions with the applicant about the placement of future construction on these lots occurring within or near more open (less wooded) parts of each lot. Individual lot tree preservation plans shall be required at the time of building permit application for lot 1 and lot 3. WATER QUALITY/WETLANDS This proposed development is located just north of Cliff Road. Holland Lake in Lebanon Hills Regional Park lies just across Cliff Road to the south. The 6.5 acre parcel contains one existing residence, and the owner is proposing to create two additional lots. Because of the small size and low density of the new development, staff recommends that a cash dedication in lieu of on-site ponding be required to meet water quality mitigation standards. Two wetlands have been located and delineated on the site. The grading plan indicates that neither wetland will be impacted by fill or drainage activities. This development is also located within the shoreland impact zone for Holland Lake. This zone extends 1000 feet back from the Ordinary High Water mark of Holland Lake and requires that certain minimum standards be met to protect the water quality and visual character associated with the. lake. The developer will need a variance to the minimum 80,000 square foot lot size for unsewered areas for Lot 3, which is about 65,000 square feet. Because the disturbed areas associated with the proposed development will be located more than 300 feet from the south property line near Holland Lake and the intervening area is heavily forested, there should be no direct visual impacts to Holland Lake as a result of the development. Staff therefore recommends approval of the variance under the current development plan. Staff recommends that • The development meet its water quality mitigation requirements through payment of a cash dedication in lieu of on-site ponding. The amount of the cash dedication should be based on the area and development intensity of the two new lots that will be created. • Filling or draining of wetlands on the site be prohibited. • A variance to the minimum lot area requirements within the shoreland impact zone for Holland Lake be granted for Lot 3. FOR COMMISSION REVIEW: 1. This development shall be responsible for a cash parks dedication for the newly created lots. 2. This development shall be responsible for a cash trails dedication for the newly created lots. 3. Individual lot tree preservation plans shall be required at the time of building permit application for lot 1 and lot 3. 4. The development shall meet its water quality mitigation requirements through payment of a cash dedication in lieu of on-site ponding. The amount of the cash dedication should be based on the area and development intensity of the two new lots that will be created. 5. Filling or draining of wetlands on the site shall be prohibited. 6. A variance to the minimum lot area requirements within the shoreland impact zone for Holland Lake shall be granted for Lot 3.

The property is relatively flat and holds few, if any, significant trees. This item is scheduled for consideration at the July 28th Advisory Planning Commission. PARKS/TRAILS DEDICATION This development shall be responsible for a cash parks dedication and a cash trails dedication. TREE PRESERVATION There is no significant vegetation on this site. WATER QUALTIY/WETLANDS This 3.2 acre site is located in Drainage Basin J and will generate runoff that will discharge through two existing sediment traps before reaching the main stem of the stormwater drainage system. The runoff will then travel through Pond JP-9 in McCarthy Park, the nearest downstream recreational water body, before reaching Fish Lake. Storm sewer discharges through the trunk system will be treated at an alum dosing station prior to discharge to Fish Lake. Because the development is small and capital improvements will be or already have been completed to protect water quality in the downstream recreational water bodies receiving runoff from this site, staff recommends a cash water quality dedication. There are no jurisdictional wetlands on the site. Staff recommends that the development meet water quality mitigation requirements through payment of a cash dedication. FOR COMMISSION REVIEW 1. This development shall be responsible for a cash parks dedication. 2. This development shall be responsible for a cash trails dedication 3.

RYAN BACKGROUND Dart Transit is proposing to construct a 215,000 square foot warehouse in Eagandale Corporate Center south of Aldrin Drive. Dart's development plan includes outside overnight truck storage at the loading docks, which requires a Conditional Use Permit. The proposed shared driveway with Lot I also requires a variance to the required pavement setback for side yards. Dart has also applied to replat the 26 acre property into two lots, with construction proposed on Lot 2, and Lot I is proposed to be graded in anticipation of future construction. The site is currently vacant. Topography is gently rolling with higher elevations in the central area of the site. The eastern one-third of the site holds a DNR protected wetland, a stormwater holding pond and a significant number of mature trees, including hardwood varieties. The proposed 215,000 square-foot warehouse is 35 feet in height and consists of one story. The loading docks are located on the east and west elevations of the building. The exterior building materials consist primarily of painted pre-cast panels, with brick at the corners of the north (front) elevation which wraps around to the east and west sides. Access to the site is proposed in two locations for Aldrin Drive. The easterly access serves Lot 2, and the westerly access will be shared with Lot 1. Forty-eight (48)-parking stalls will be constructed with the building, and the balance of the 224 required parking stalls is shown as proof of parking east and south of the building. PARKS/TRAILS DEDICATION This entire area (Dart Property) has previously been recommended for cash park and cash trail dedication. This development should, therefore, be the same. The developer/owner is requested to consider a soft surface trail along the pond extending from the school property to the south. This trail may be difficult to construct because of steep slopes and the possibility of encroachment into the 30 foot wetland setback. TREE PRESERVATION The submitted tree inventory indicates that there are ninety-eight (98) significant trees on site. Tree species and sizes include oak trees (6" to 36" diameter), maple trees (6" to 48" diameters), Ohio Buckeye trees (8" to 15" diameter), elm trees (6" to 36" diameter), spruce and pine trees (25' to 40' in height, as well as some boxelder, willow, and cottonwood trees. A summary of tree statistics is provided below. Trees Existing vegetation 98 To be removed 42 (42.9%) To be preserved 56 (57.1%) Allowable removal 30% (29 trees) Calculated mitigation 36 Category B trees According to the City of Eagan Tree Preservation Ordinance, allowable removal for this type of development (commercial, single lot) is set at 30% of the existing significant vegetation. Mitigation for tree removal in excess of allowable limits calculates to eight-teen (18) Category A trees or thirty- six (36) Category B trees or seventy-two (72) Category C trees. This tree preservation mitigation is in addition to any landscape requirement (see Recommendation section for staff requirement related to this issue). Tree Preservation Areas Versus Grading Limits Staff reviewed the proposed Grading, Utility, and Erosion Control Plan versus the proposed location of the required tree protection fence and found that there is an overlapping of these two areas. In other words there are trees indicated on the tree preservation plan which are shown not to be removed, but are located within proposed grading areas. According to the City of Eagan Tree Preservation Ordinance, there is to be no encroachment or grade change within areas where trees are to be preserved. A revision of either the grading plan or the tree preservation is required which will show more accurately the limits of grading and the areas of tree preservation. Landscape Requirement Versus Tree Preservation Mitigation A Landscape Plan has been submitted for this development proposal that includes both landscape trees and tree preservation mitigation trees. Forestry staff has had discussions with city planning staff concerning the fulfillment of the landscape requirements and tree preservation mitigation. The submitted landscape plan does not satisfy these requirements (the amount of vegetation on this plan only satisfies the landscape requirement). Staff recommendation is that a revised Landscape Plan/Tree Mitigation Plan be submitted by the applicant which includes an additional 36 Category B trees to serve as mitigation for tree removal in excess of allowable limits. These additional tree mitigation trees should be installed into the areas east of the proposed building and parking lot, to the area between and around the two water bodies, and to the area south of the proposed building. Recommendation Staff is recommending denial of the submitted Tree Preservation Plan until the following conditions are met: • Indicate on a revised Landscape Plan/Tree Preservation Plan size, species and location of 36 Category B mitigation trees, (or an equivalent combination of Category A or Category C trees). These 36 mitigation trees are in addition to any City of Eagan landscape requirements. If all 36 trees cannot fit on this site, they may be installed on other applicant property within the City of Eagan, or a cash mitigation option may be applied. • Indicate on a revised Grading Plan and a revised Tree Preservation Plan proposed grading limits and the location and type of Tree Protection Fence. Tree Protection Fence is to be placed at the edge of the Critical Root Zone (a distance of one foot per inch of tree trunk diameter). d_ ~ • Indicate on a revised Tree Preservation Plan site/soil restoration efforts in areas where trees are to be preserved (areas east and southeast of the building, where trees are indicated to be preserved, have had fill brought in over the Critical Root Zone, this fill must be removed to original grade). WATER QUALITY/WETLANDS This development is located within the Eagandale Corporate Center complex, a 200-acre industrial park located northeast of the Lexington Avenue and Yankee Doodle Road intersection. The parcel for which the conditional use permit is requested is between two state protected waters, Ponds DP- 11 and EP-3. The western two-thirds of the site will generate runoff that will discharge to an existing detention basin that discharges to Pond DP- 11. Similarly, the remainder of the site will discharge to an existing detention basin that in turn discharges to Pond EP-3. Both detention basins were constructed by the developer after City staff review and will adequately treat this runoff. The only wetlands on the site are the two state protected wetlands. Conditions associated with the preliminary subdivision approval of this development mandated that an ungraded, un-maintained buffer extending at least 30 feet back from the delineated wetland edge for each wetland be preserved. The grading limit for the development is just outside this buffer. There have been chronic erosion problems in this portion of the ECC site which have impacted Pond DP- 11. While those problems have largely been corrected, special erosion and sediment control measures have been incorporated into the revised grading plan dated June 30, 1998 to prevent a recurrence of problems when this site is disturbed again for development. These provisions include repair of an eroded gully in the south central part of the site. Staff recommends that: • All runoff from impervious areas be directed to existing detention basins for treatment as per the master drainage plan for the development. • An ungraded, un-maintained buffer extending at least 30 feet back from the delineated edge of all wetlands on the site be preserved. • The erosion and sediment control provisions identified on the grading plan dated June 30, 1998 be followed. • All graded areas with a slope greater than 4:1 be permanently established in a native perennial grass cover using MnDOT seed mix 20A or equivalent and that this vegetation be left in an un-maintained condition. a1 FOR COMMISSION REVIEW 1. This proposal shall be responsible for a cash parks dedication. 2. This proposal shall be responsible for a cash trails dedication. 3. Staff is recommending denial of the submitted Tree Preservation Plan until the following conditions are met: • Indicate on a revised Landscape Plan/Tree Preservation Plan size, species and location of 36 Category B mitigation trees, (or an equivalent combination of Category A or Category C trees).

If all 36 trees cannot fit on this site, they may be installed on other applicant property within the City of Eagan, or a cash mitigation option may be applied. • Indicate on a revised Grading Plan and a revised Tree Preservation Plan proposed grading limits and the location and type of Tree Protection Fence. Tree Protection Fence is to be placed at the edge of the Critical Root Zone (a distance of one foot per inch of tree trunk diameter). • Indicate on a revised Tree Preservation Plan site/soil restoration efforts in areas where trees are to be preserved (areas east and southeast of the building, where trees are indicated to be preserved, have had fill brought in over the Critical Root Zone, this fill must be removed to original grade). 4. All runoff from impervious areas shall be directed to existing detention basins for treatment as per the master drainage plan for the development. 5. An ungraded, un-maintained buffer extending at least 30 feet back from the delineated edge of all wetlands on the site shall be preserved. 6. The erosion and sediment control provisions identified on the grading plan dated June 30, 1998 shall be followed. 7. All graded areas with a slope greater than 4:1 shall be permanently established in a native perennial grass cover using MnDOT seed mix 20A or equivalent and that this vegetation be left in an un-maintained condition.

To provide a recommendation as to general conditions for site development for this property as a framework upon which specific conditions and detailed plans can be developed. MEMO city of eagan TO: ADVISORY PARKS COMMISSION FROM: KEN VRAA, DIRECTOR OF PARKS AND RECREATION DATE: JULY 15,1998 SUBJECT: OAKBROOKE SUBDIVISION - BIETER PROPERTY BACKGROUND In December 1996, the City denied Pulte's development request that included a Preliminary Planned Development for a mixed residential development consisting of 502 dwelling units. In April 1997, Pulte submitted a development request, which included re-zoning to Residential Double (R-2), and a preliminary subdivision consisting of 171 lots for 342 twin home dwelling units. In June of 1997, the City Council adopted an interim Ordinance creating a moratorium on development of property designated in the Comprehensive Guide Plan as D-II, mixed residential, (0-6 units per acre). Subsequent to the City's adoption of the Interim Ordinance creating the moratorium, the property owner initiated litigation against the City. • Over the past several months, attorneys for the City and property owner, have been engaged in efforts on behalf of their respective clients to resolve this dispute. Informal discussions were held regarding the common interests of the parties and the concept of creating a neighborhood of a mixture of single family lots and single family lots floating in surrounding common areas, with an overall density not to exceed three units per acre. The City planning staff has worked with Pulte in their preparation of a conceptual site plan for the proposed Oakbrooke development. The concept of the Oakbrooke site plan submitted calls for 313 total single family detached dwelling units. 166 units are located on the west side of the Johnny Cake Ridge Road extension and will be located on lots that reflect the footprint of the individual building. All common area will be governed by a homeowners association that will manage all exterior building maintenance, lawn care, irrigation, snow removal, architectural control and common element maintenance. The plan also calls for 147 single-family units on the east side of Johnny Cake Ridge Road on lots of a minimum width of 55 feet with a minimum setback distance between buildings of 15 feet. A homeowners association will manage architectural control and common element maintenance for this portion of the site. The proposed 313 units on 117 acres results in a gross density of 2.67 units per acre. PREVIOUS COMMISSION ACTION Attached on pages ..S5- 4 is the information that was provided in May, 1997 when the Commission last reviewed a proposed development on this property. • PARKS/TRAILS DEDICATION Based on previous recommendations, a cash parks dedication would be required along with a trail/sidewalk along Johnny Cake Ridge Road with connection to the school property to the east. TREE PRESERVATION This piece of property was last seen for development review in May 1997 as Oakbrooke development. Included below in italics is the report provided to the APrC in the May 1997 packet. 1997 APrC Report A tree preservation plan and a tree inventory have been submitted for this development. The inventory indicates that current significant vegetation consists of 1,133 significant trees. Significant vegetation on this large site consists of a variety of deciduous trees and small patches of coniferous trees. Most of the vegetation is located near waterbodies and on hillsides. The development as proposed will result in the removal of 477 significant trees (42% of the total). Thirty-eight trees (3.4% of the total) will be removed though the construction of Johnny Cake Ridge Road. This tree removal is exempted from the applicant's responsibility. According to the City of Eagan Tree Preservation Ordinance, allowable removal for this type of development (single phase, multi-lot, multi-unit residential) is set at 47.5%. With a tree/woodland removal less than allowable limits, there is no mitigation requirement. Recommendation Staff is recommending approval of the Tree Preservation Plan as proposed with the following conditions: • To require that Tree Protective measures (i.e. 4 foot 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. • To require that the applicant contact the City Forestry Division at least five days prior to the issuance of the grading permit to ensure compliance with the approved Tree Preservation Plan. 1998 Development Proposal Review This site has suffered some vegetation damage from the 1998 storms (large tree blow down, branch breakage, etc.) The tree inventory should be updated accordingly. Without the availability of a grading plan, 1998 proposed site disturbance appears to be approximately the same as what was proposed in 1997. The 1997 proposal had a proposed significant tree removal less than what would be allowed by the Tree Preservation Ordinance (42% proposed removal versus 47.5% allowable removal; data is for the entire site). Following staff review it appears that 1998 tree impact will be close to or within allowable limits. Conditions Staff is recommending the following conditions be applied to this development: • To require that the tree inventory be updated per existing conditions. • To require that significant tree/woodland removal in excess of allowable limits be mitigated per Tree Preservation Ordinance. 3U WATER QUALITY/WETLANDS Development of this site will generate runoff that will reach Blackhawk Lake a short distance downstream. Blackhawk Lake is one of seven Class I direct contact recreation lakes identified in the City's water quality management plan and is the City's second highest priority for long-term enhancement of water quality. Due to the size of the development and the potential for water quality degradation in Blackhawk Lake, staff recommends that on-site ponding be the primary means used to meet water quality mitigation requirements. Because the development plan now before the Commission proposes development at a higher density than the plan submitted in 1997, impervious coverage will likely be greater, and additional on-site ponding capacity may be required. Further, staff recommends that the large constructed ponding area (Pond BP-35) in the southwest area of the site be used to treat runoff from as much of the development as possible. As with the 1997 development plan, the developer will need to construct a large detention basin just south of Deerwood Drive to treat runoff from the northcentral and eastern portions of the site prior to discharge off the site. Sizing of the detention basin cannot be completed until a utility plan and grading plan for the site are available for review. The wetland survey for this site identifies five wetland basins totaling 3.3 acres. Four of the basins are natural wetland basins, while the fifth-designated Pond BP-35 in the City's stormwater management plan-has been significantly modified and deepened. Staff recommends that that discharge to the natural wetlands of untreated runoff from impervious surfaces be prohibited. In addition, draining or filling of jurisdictional wetlands other than that allowed by exemptions should also be prohibited. Finally, it is recommended that an un-maintained, un-graded buffer extending at least 30 feet back from the delineated edge of the wetland be preserved around all five wetland basins on the site. Staff recommends that the following conditions apply to development of this parcel: • On-site ponding be the primary means to meet water quality mitigation requirements to protect Blackhawk Lake. A supplemental cash dedication will be considered only after City water resources staff are satisfied that additional on-site ponding or other mitigation within the development site is not a practical option in reaching management objectives for Blackhawk Lake. • The on-site ponding and stormwater routing configuration for the development shall be constructed as directed by City water resources staff. • Outlet skimmers constructed in accordance with the City's standard detail plate shall be installed on Ponds BP-35 and BP-3. • No discharge of untreated water from impervious surfaces to the four natural wetland basins within the development is allowed. • Draining or filling of jurisdictional wetlands within the development other than that allowed by exemptions under the Wetland Conservation Act is prohibited. • Un-maintained, un-graded buffers extending a minimum of 30 feet back from the delineated edge of the wetland shall be preserved around all five wetland basins within the site. 21, FOR COMMISSION REVIEW To provide a recommendation as to general conditions for site development for this property as a framework upon which specific conditions and detailed plans can be developed. 612 432 3780 SENT BY : 7- 6-98 13:31 : SEVERSON SHELDON- 681 4694 : x 12:12 _4- 1 _ (~-[YCL ~(r a t` % . _ 'ZERWooo Dft1vE a c % Y m Cola IJ P.. / ( Z_ 11 , --Z - 7, -Q.

Is requesting approval of a Rezoning from Agricultural (A) and Roadside Business (RB) to Residential Double (R-2) and a Preliminary Subdivision consisting of 171 lots and three outots on approximately 117 acres. Pulse is proposing to Rezone the entire area to R-2, Double. The R-2 Zoning District requires a minimum lot size of 15,000 SF and a minimum lot width at building setback of 100 feet. The duplex units are marketed under two different model names and the base units range in size from 1,450-2,375 SF. The site development plans show a five acre exception parcel in the very northeastern comer of the site; however, the developer has provided development plans showing the ultimate development of the property including this exception. As shown, this five acre parcel could be Incorporated Into the Pulse project In the future and would provide the development of two additional single family lots (one with the existing Franz home) and 19 additional club home units In five buildings. All of the lots meet or exceed the minimum requirements of the R-2 Zoning District. The developer is proposing to plat three outlots Earlier this year Rotdund Company requested a Comprehensive Guide Plan Amendment to change the Land Use Designation of the southwesterly eight acres of the Bieter property from D-li, Mixed Residential (0-6 u/ac) to Roadside Business, RB. This request was denied by the City Council. In September of 1996, Pulse submitted a development request that included a Preliminary Planned Development to allow a mixed residential development consisting of 502 dwelling units and a Preliminary Subdivision consisting of 218 lots. At that time, Pulse was proposing a "Life Cycle Community" that included five residential product lines that would provide housing opportunities for people at various stages of life from the first time home buyer to the empty nester. The product lines Included two different types of single family homes and three types of attached multiple family units. This development request was denied by the City Council late last year. PARKS/TRAILS DEDICATION The Commission reviewed development of this site in September of 1996. At that time staff prepared background history to help the Commission understand what has occurred at this site in the past. A copy of the September 12, 1996 memo is enclosed to refresh the Commission's memory and minutes of the September 16 Commission meeting are also enclosed for additional background. Based on the Commission's previous recommendations, this development would be subject to a cash parks dedication and a cash trails dedication. ,~s TREE PRESERVATION A tree preservation plan and a tree inventory have been submitted for this development. The inventory indicates that current significant vegetation consists of 1,133 significant trees. Significant vegetation on this large site consists of a variety of deciduous trees and small patches of coniferous trees. Most of the vegetation is located near water bodies and on hillsides. The development as proposed will result In the removal of 477 significant trees (42% of the total). Thirty-eight trees (3.4% of the total) will be removed though the construction of Johnny Cake Ridge Road. This tree removal is exempted from the applicants responsibility. According to the City of Eagan Tree Preservation Ordinance, allowable removal for this type of development (single phase, multi-lot, multi-unit residential) is set at 47.5%. With a tree/woodland removal less than allowable limits, there Is no mitigation requirement. Staff is recommending approval of the Tree Preservation Plan as proposed with the following conditions: • To require that Tree Protective measures (i.e. 4 foot 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. • To require that the applicant contact the City Forestry Division at least five days prior to the Issuance of the grading permit to ensure compliance with the approved Tree Preservation Plan. WATER QUALITY/WETLANDS Water Quality This development will generate runoff that will reach Blackhawk Lake a short distance downstream. Blackhawk Lake Is one of seven Gass I direct contact recreation lakes identified In the CIty=s water quality management plan and is the City=s second highest priority for long-term enhancement of water quality. Because of the size of the development, staff recommends that on-site ponding be the primary means of meeting water quality mitigation requirements. As per staff request, a large constructed ponding area (Pond BP-35) in the southwest area of the site will be used to treat runoff from over half of the development. The north-central and eastern portions of the site will drain to the north, and staff has directed the developer to construct a detention basin to treat this runoff prior to discharge off the site. Routing off storm water through the ponds on the site has been designed to maximize removal efficiencies. The ponding designations for the development is shown in Figure 1. Even with these on-site mitigation measures, modeling indicates that a very slight degradation of water quality in Blackhawk Lake will occur. Further, the degradation is virtually unavoidable with conventional on-site treatment practices at any density of standard residential development, although the shortfall in meeting treatment goals is slightly worse with the proposed multi-family development than it would be with a lower density residential development. Staff recommends a supplemental cash dedication to meet the remaining mitigation requirements that cannot be met through on-site ponding. This dedication would be used to off-set costs of In-lake treatment and other measures necessary to manage Blackhawk Lake In the future. Wetlands. The wetland survey for this site identifies five wetland basins totaling 3.3 acres. Four of the basins are natural wetland basins, while the fifth-designated pond BP-35 in the City's storm water management plan-has been significantly modified/deepened. Staff has requested that the developer avoid discharge of runoff from impervious surfaces to the four natural wetland basins, and the developer has accommodated this request. No filling or draining of wetlands is proposed. However, there are numerous areas where grading and building pads come right to the delineated edge of the wetland. Staff recommend that a wetland buffer recommendation similar to the one adopted for the previous development plan for this site (Rolling Oaks) be considered. That recommendation called for natural ungraded buffers extending at least 30 feet back from the delineated edge of the wetland be preserved around all five basins on the site, with one exception for a road embankment adjacent to the southern end of Pond BP-3.4. Compliance with this recommendation would require elimination or modification of grading plans for ten lots within the development. Staff recommends that: • On-site ponding be the principle means of meeting water quality mitigation requirements. • Ponds BP-35 and BP-3.3 have minimum wet volumes of 10.6 acre-feet and 2.7 acre-feet, respectively, and that they meet the City's standards for detention basin design. • A supplemental cash dedication be required to make up for any shortfall in on-site treatment. • Draining or filling of wetlands be prohibited. An ungraded buffer of natural vegetation extending at least 30 feet back from the edge of the wetland units associated with Ponds BP-25, BP-25. 1, BP-3.2, and Pond BP-3.1 be preserved. Where grading for roadway construction around the southern tip of Pond BP-4 Is proposed, the area within 30 feet of the wetland boundary shall be established in native perennial grasses and left in an un-maintained condition. The buffers shall be identified on the grading plan. RECOMMENDATIONS 1. This development would be subject to a cash parks dedication. 2. This development would be subject to a cash trails dedication. 3. The Tree Preservation Plan should be approved as proposed with the following conditions: • To require that Tree Protective measures (i.e. 4 foot 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. • To require that the applicant contact the City Forestry Division at least five days prior to the issuance of the grading permit to ensure compliance with the approved Tree Preservation Plan. 4. On-site ponding be the principle means of meeting water quality mitigation requirements. 5. Ponds BP-35 and BP-3.3 have minimum wet volumes of 10.6 acre-feet and 2.7 acre-feet, respectively, and that they meet the City's standards for detention basin design. 6. A supplemental cash dedication be required to make up for any shortfall in on-site treatment. 7. Draining or filling of wetlands be prohibited. 8. An ungraded buffer of natural vegetation extending at least 30 feet back from the edge of the wetland units associated with Ponds BP-25, BP-25.1, BP-3.2, and Pond BP-3.1 be preserved. Where grading for roadway construction around the southern tip of Pond BP-4 is proposed, the area within 30 feet of the wetland boundary shall be established in native perennial grasses and left in an un-maintained condition. The buffers shall be identified on the grading plan. 7, t9A•p. tt,i' to•. ' i 00t:•K• (4U ltp.. ttlai tAiw '1.O.i t..•OL.K M L.oO...Oi]n R j •..ars Y.I~r.

Except for a small sliver in the southwestern portion of the site that is currently zoned Roadside Business, the entire site is zoned Agricultural and guided D-II Mixed Residential (0-6 units/acre). The proposal includes a rezoning of the approximately 120 acre site to Planned Development and a Preliminary Subdivision to allow a total of 523 residential units. The proposal includes 80 singel family homes and the remaining 443 units are made up of a mixture of three different types of attached residential units. The proposal includes the extension of Johnny Cake Ridge Road through the property from Diffley Road to Deerwood Drive. Additional coneections include extending Cashell Glen Road from the east to this site and also a secondary access to the site's pbulic street system for the school district for the Blackhawk Middle and Deerwood Elementary Schools. While Johnny Cake Ridge Road wil be extended through the site, the development is anticipated to be in two phases with Phase I occurring on the southern half of the property. PARKS AND TRAILS DEDICATION BACKGROUND The developer's plan calls for a total of 523 residential units to be built; 80 single family, 320 court/village homes and 123 club homes. At an average density of 2.72 people expected population of this development would be approximately 1,423 per unit, the y people. The site will be bisected by Johnny Cake Ridge Road, a collector street which is proposed to have a 36 foot wide street with sidewalk on one side and a bituminous trail on the other. The road right-of- way will be 70 feet. Also within Park Service District #21 are Deerwood townhomes with 36 residential units, Kingswood with 118 residential units and other residential developments totaling 198 units. The approximate total population for this park service district at full development is estimated to be 2,380. A park dedication of 16.23 gross acres is proposed by the developer, Pulte Homes. This amount exceeds the normal dedication of 10%, however, delineation of wetlands and slopes have not been calculated. The Commission previously reviewed a development proposal by Rottlund Homes on this site and recommended a cash parks and trails dedication. One of the reasons for that decision included questioning the need for a neighborhood park in this location since Deerwood Elementary and Blackhawk Middle Schools to the east provide considerable recreational amenities; more than most neighborhood parks. Those amenities include two baseball fields, one softball field, two overlay soccer fields, a football field, running track, four tennis courts, two playgrounds and additional indoor recreation. 41, Another consideration for a cash dedication was the fact that this development is within the 1/2 to % radius of three neighborhood parks. Those include Camelian Park located on Blackhawk Road, Heine Pond Park on Diffley Road and Downing Park adjacent to Oak Ridge Elementary School. Blackhawk Community Park is also located only 1/2 mile north. Of the skating, parks listed shelter Heine Pond Park offers a canoe launch; Carnelian Park offers hockey, pleasure building, playground, basketball and a ballfield; Downing Park offers a ballfield, playground, soccer overlay and hard acourt; and Blackhawk offers winter ysextensive trails, fishing war warming shelter, large playground, observation deck, picnic pavilion, pier and canoe launch. - HISTORY The issue of providing a park in Service District #21 has a long history dating back to the late 70's/early 80's. The unusual shape of the district alone makes the siting of a park difficult. The district is bounded by 35E, Pilot Knob Road and Diff ley Road. The existing Deerwood now Johnny Cake Ridge Road, makes the justification fthe icat oni Elementary School rwwas once the ood Road, and identified district or a d park diffspliticuIt lt Dee because of limited population thresholds in each of these smaller areas defined by major streets. When Deerwood Elementary School was sited, the City was still hopeful of next to the elementary school, with other developing neighborhood school/ in middle school conjunction was sited the school/park sites. . When the a neighborhood park all but disappeared since most recreational amenities were being provided 40 acres were removed from by the two schools. With the development of these two schools, the service district that would have normally been residential development reducing the project service population. As the development of this service district has unfolded, the uncertainty size. the 4-6 acresmientions about a park has continued commons hhne neighborhood plan update possibility of only a a neighborhood or ANALYSIS OF PROPOSED PARK DEDICATION Two separate parcels are proposed by the developer for parks dedication. The first parcel consists of 4.32 acres of land and is located in the east central region of the site. This is an area of rolling hills and lush vegetation. Eighty single family residences are planned to surround this area. Pulte Homes is proposing to maintain a core of open space on the back well Droivfetanhese one homes. Three points of access are shown for this open space; two on Cornd e makes a on Johnny Cake Ridge Road. t foot o delcoerridor ins shown end of ton heesou hcside of th scwetlandity questionable. A very the 920 with a skimmer at elevation 920.0 feet. Unfortunately, according to the grading plan, contour extends further to the south indicating this access point may be flooded for indefinite periods. The other access point off Cornwell Drive near data, slopes tiie not excess of . Cashell hhas a%steeince grades to contend with. According to the topographic be to oreaso ablly graue the theite. If only a 20 foot wide corridor is shown, there is insufficient ient room room was available to properly grade the site, the grading requirements of this site, building a trail as proposed would be costly and require the removal of additional trees. Although scenic, the majority of the proposed 4.32 acre park dedication contains a considerable amount of steep topography and wetlands which would be difficult to provide trail access. The value of this parcel to the adjacent landowners may be significant, however, the value of this parcel to the Eagan Park System, because of the difficulty of access, is negligible. The second proposed site consists of 11.91 acres of land. To the west of this parcel abuts el Interstate 35E and the water tower just south of Deerwood. This is a heavily wooded parcel with steep slopes up to 33%. The developer is suggesting a sledding hill for this site, however, the only area without trees is a thin sliver of land nithtthe~steethis epestlsl owed with da grade ofor approximately 30%. The velocity of a sled trave)g d most sliders. The likelihood of personal injury would not justify the st4 hrill the th accee of this . At hill are two wetlands. The northern most wetland consumes about of the west and north sides of this proposed park dedication. Due to this constriction, a future trail here could be expensive to construct. Moving northeast from this wetland, the developer is suggesting two hockey rinks and a warming house. Eagan park standards suggest ice hockey rinks should serve a'h mile service area. Currently there are 4 ice hockey rinks within this service area; one at Carnelian, one at Woodhaven and two at Sky Hill Park. The department recently completed a combination picnic shelter and warming house at Blackhawk Park only ' mile to the north. According to the grading plan, the proposed warming house is shown constructed at the edge of a steep drop off. Typically the grade between warming house and ice is flat or nearly flat so skaters can easily travel back and forth. The north end of the parking lot is shown at an elevation of 930 ft. The building site is shown at around 922 ft. The distance of 80 feet has a 10% slope and ADA accessability standards call for a maximum 5% slope. SUMMARY 1. Given the facts, it appears the Rolling Oaks site could be well served by recreational opportunities at Carnelian, Downing, Heine Pond and Blackhawk Parks with additional recreational opportunities available at both Deerwood Elementary and Blackhawk Middle School. 2. Recreational opportunities proposed by the developer would be a replication of existing nearby facilities. The cost of hockey rinks, warming house, utilities, parking lot, lighting and trails would exceed $250,000. 3. Site grading would be costly due to the high percentage of steep slopes in the proposed park dedication areas. 4. ADA accessability standards would be difficult to meet at numerous locations. 5. Trees and other vegetation would be removed in the .process of grading to achieve access and to make the park usable. 6. The 4.32 acre site benefits only the adjacent homeowners. A neighborhood park should serve a much broader area. ALTERNATE CONCEPTS FOR CONSIDERATION 1. A site which may serve park needs better would be a 6 acre parcel located in the northeast corner of the Rolling Oaks development. This site is bounded by school property to the east, Cashell Road to the south, Cornwell Drive to the southwest, Johnny Cake Ridge Road to the west, Hackberry Circle to the north and an existing single family home which lies within an area marked as "exception" on the development maps. A 6 acre park acquisition at this location could complement existing facilities at the adjacent school, i.e. picnic and scenic opportunities. This site is also centrally located within Park Service District #21. Placing the main park acquisition to the northwest separates it from the schools by Johnny Cake Ridge Road. It also exposes park users to the high level of noise which spills over from 135E traffic. A northeast location may also be more convenient for other residents of Park Service District #21 who live in Deerwood Townhomes or at Kingswood. Future expansion might be possible at this site if the owners of the single family residence to the north would be willing to sell. This site offers good views of the Twin Cities skyline and gentle slopes would minimize park development costs. 2. The Commission has previously looked at this parcel for open space preservation. The Commission may want to consider acquisition of property for this purpose. The Commission recognizes that some of the proposed parkland is likely to remain open regardless of the City's final decision as to whether to acquire it for parks given that it is likely to be preserved through tree preservation and/or wetland preservation standards. A6 TREE PRESERVATION The following is a tree preservation summary calculated from the revised plan submitted September 9, 1996. This item was originally presented at the August APRNRC meeting. Tree preservation changes with this revised plan have resulted from the following actions: a. realignment of Johnny Cake Ridge Road, b. alteration of grading limits, c. introduction of proposed parkland within the development, d. shifting of culdesac locations, e. alteration of building pad locations, and f. recount of existing trees on site (trees within Johnny Cake Road right-of-way not included, and the exclusion of storm damage trees). Significant Vegetation The submitted revised Tree Preservation Plan indicates that there are 1,052 significant trees on the site. The development as proposed will likely result in the removal of 434 trees (41.3% of the total). Details of this removal percentage are provided below. Multi-Unit Residential (Allowable removal for single-phase development - 47.5%) Trees to be removed = 207 (50% of total) Trees to be preserved = ZU (50% of total) Total existing trees = 413 Single Family Residential (Allowable removal for single-phase development = 40.0%) Trees to be removed = 217 (34.0% of total) Trees probably preserved = 19 (3.0% of total) Trees to be preserved = AU (63.0% of total) Total existing trees = 639 Utility Installation (Storm Sewer Construction) Trees likely to be removed = 10 (1.0% of the total) Total Site Data Trees to be removed = 434 (41.3%) Trees to be preserved = n.h (58.7%) Total existing trees = 1052 The developer is proposing to prepare the entire site at one time, with the exception of some custom grading on the single family residential lots. Staff has calculated an average allowable removal for this entire site based upon a 40.0% allowable removal for single family residential development and a 47.5% allowable removal for multi-unit residential development. The resulting average allowable removal is set at 43.75%. With a proposed significant tree removal for the entire site not exceeding the allowable limit, there is no tree mitigation. Additional Concerns Staff is recommending that the storm water drainage system which runs from the low area in the north part of the single family development area through the proposed "hockey rink" parking lot to drainage pond BP-3 be raised in elevation and redirected through single family lots 5 and 6 and between Clubhouses 25 and 26. This raising and redirection should result in the avoidance of additional significant tree removal in both the large preserved area within the single family development and in the significant spruce and hardwood stand south of drainage pond BP-3. It is likely, however, that approximately 10 significant trees will be removed through construction of storm drainage systems throughout the remainder of the site. This tree removal is mentioned in the table above. Staff is also recommending that the developer work with the city in attempts to preserve additional significant trees located in areas within construction limits. These areas would generally be located in front of the "coved lots", on or near property lines, or along road right-of-ways where there will be minimal grade changes. Field reviews are recommended after roads are staked and prior to any grading or tree removal to identify any significant tree which could possibly be preserved. WATER DUALITY/WETLANDS Water quality This development will generate runoff that will reach Blackhawk Lake a short distance downstream. Blackhawk Lake is one of seven Class I direct contact recreation water bodies identified in the City's water quality management plan and is the City's second highest priority for long-term enhancement of water quality. Because of the size of the development and the existence of a high priority recreational water body downstream, staff recommends that on-site ponding be the primary means of meeting water quality mitigation obligations. As per staff request, a large constructed ponding area (Pond BP-35) in the southwest area of the site will be used to treat runoff from over half of the development. The north-central and eastern portion of the site will drain to the north, and staff has directed the developer to construct a detention basin to treat this runoff prior to discharge off the site. In the most recent set of plans, the detention basin is too small to provide the high level of treatment required to meet non-degradation standards for Blackhawk Lake. Whether the pond can be expanded will depend on whether the proposed park area to the west on this pond remains a .part of the development. If the area is not needed for a developed park facility, staff recommend that this detention basin be increased in size and volume to improve the pollutant removal efficiency of the pond. Even with the expansion of Pond BP-3, modeling indicates that a slight degradation of water quality in Blackhawk Lake will occur. Rather than require the significant increase in on-site ponding that would be necessary to fully meet the non-degradation standard for Blackhawk Lake, staff recommends a supplemental cash dedication to meet mitigation requirements. The cash dedication would be higher if pond BP-3 cannot be expanded over that proposed. This dedication would be used to off-set costs of in-lake treatment measures to protect water quality in Blackhawk Lake. Wetlands The wetland survey for this site identifies five wetland basins totaling 3.3 acres. Four of the basins are natural wetland basins, while the fifth-designated Pond BP-35 in the City's storm water management plan-has been significantly modified. Staff has requested that the developer avoid direct discharge of runoff from impervious surfaces to the four natural wetland basins, and the developer has accommodated this recommendation. The developer is proposing a partial fill of a small Type 2 wetland in the northwest portion of the site. The Wetland Conservation Act allows filling of up to 2,000 square feet of wetlands of this type before mitigation is required. The developer has indicated that the area filled will not exceed this figure, though the grading plan dated August 30, 1996 shows a fill of approximately 3,000 square feet. None of the other wetlands would be filled or drained under the current development proposal. Finally, with two exceptions, the grading plan shows ungraded buffers around the four natural wetland basins that range from 30 to over 300 feet in width. One exception is an area around the southern end of the wetland basin BP-3.4, where a proposed road would come within about 15 feet of the wetland edge. The other is associated with the fill proposed for wetland basin BP-3.3. It should also be noted that wetland units associated with Ponds BP- 3.4 and BP-3.3 will be part of a proposed natural corridor in the western area of the parcel and that the wetland unit associated with Pond BP-25 and BP-25.1 will be part of a larger environmental corridor in the southern and eastern portion. Advisory Parks, Recreation and Natural Resources Commission Minutes of September 16, 1996 Meeting Page 2 DEVELOPMENT PROPOSALS ROLLING OAKS • PULTE HOMES Following a brief introduction by Director Vraa, Senior Planner Ridley noted that this item was addressed at the August Advisory Commission meeting at which time it was deferred to the Natural Resources and Land Acquisition Subcommittees. The primary change since the Commission's last review was the exclusion of a five acre parcel in the northeast portion of the site where a home is currently located. The developer has not been able to acquire the property at this time, thus the development has been reduced to 116 acres. This results in a decrease of units from 523 to 502, Ridley added. Director Vraa provided the Commission with the background and history of this site noting that the existing Deerwood Elementary School was once the identified location for a park in Service District #21 which is bounded by 35E, Pilot Knob Road and Diffley Road. Having the district split by Deerwood and now Johnny Cake Ridge Road, creates limited population thresholds in each of these smaller areas. When Deerwood Elementary was sited, the City was still hopeful of developing a neighborhood park adjacent to the school as has been done with other school/park sites. When the middle school was sited next to the elementary school, interest in a neighborhood park all but disappeared since most recreation amenities were being provided by the two schools. The uncertainty of a park in this service district continued even to the extent that the most recent Park System Plan update mentions the possibility of only a neighborhood commons or neighborhood park of 4-6 acres in size. Director Vraa added that a development at this site had been reviewed several months earlier at which time the Commission recommended a cash parks dedication and cash trails dedication. The developer presented two proposed parcels for parkland consideration. A 4.32 acre site located in the east central region of the site. Although scenic, the majority of the proposed dedication site contains steep topography and wetlands which would be difficult to provide trail access. The second is a 11.91 acre parcel that abuts 35E to the west and the water tower just south of Deerwood. This heavily wooded parcel also has steep slopes up to 33%. Two wetlands are located on the west and north sides of this proposed park dedication. Vraa continued that the subcommittees looked at all the options proposed by the developer for proposed park dedication and felt that even if a portion of the land could be used for park purposes, there was concern about placing a park in an area where there are several existing parks with amenities that could support this neighborhood. Director Vraa concluded stating that the Commission could look at a cash parks and trails dedication, look at a land dedication and consider what options should be considered for that site, or suggest another parcel of land within the site for parks dedication. Coordinator Brasch noted that the construction of a basin in the north central location of the site would be impacted based on parks dedication. The north-central and eastern portion of the site will drain to the north and staff has directed the developer to construct a detention basin to treat this runoff prior to discharge off the site. In the most recent set of plans, the detention basin is too small to provide the high level of treatment required to meet non-degradation standards for Blackhawk Lake. Whether the pond can be expanded will depend on whether the proposed park area to the west of this pond remains a part of the development. If the area is not needed for a developed par facility, staff recommends that this detention basin be increased in size and volume to improve the pollutant removal efficiency of the pond. Rather than require the significant increase in on-site ponding that would be necessary to fully meet the non-degradation standard for Blackhawk Lake, staff recommends a supplemental cash dedication to meet mitigation requirements. The cash dedication would be higher if pond BP-3 cannot be expanded over that proposed. This dedication would be used to off-set costs of in-lake treatment measures to protect water quality in Blackhawk Lake. Forestry Supervisory Hove noted the tree preservation changes with the revised plan resulted from the realignment of Johnny Cake Ridge Road, alteration of grading limits, introduction of proposed parkland within the development, shifting of cul-de-sac locations, alteration of building pad locations and recount of existing trees on site (trees within Johnny Cake Ridge Road right-of-way not included, and the exclusion of storm damage trees). With the developers proposed significant tree removal for the entire site not exceeding the allowable limit, there is not tree mitigation, Hove concluded. Member Szott asked about the 5 acre exception to this plat. Director Vraa stated that the property is privately owned and has been withdrawn from the original proposed site, however it was left in the plan to show what the potential development could be on the exception were it to be developed later. Member Rudolph asked how many units were expected to be built with and without the exception parcel. Senior Planner Ridley responded there were S02 proposed without the exception and 523 with the exception. A /I Advisory Parks, Recreation and Natural Resources Commission Minutes of September 16, 1996 Meeting Page 3 Member Petersen asked what kind of slopes were on the 4.32 acre proposed park. Director Vraa explained that it was very steep on the north end of the site and also on the south side which would make it difficult to place a trail around the wetland. Consideration may be given to bringing a trail from the south, however. Member Petersen clarified that a trail would be one of the only options on the 4.32 acre parcel. Gary Grant, Pulte Homes addressed the Commission stating they were looking forward to providing a good project in this area. He noted that the density is lower than what this property is zoned for and they have worked very hard to adjust the plan to preserve trees on site. It is anticipated that this neighborhood will have approximately 140 children living in it and Pulse feels that is a large enough number to warrant recreational amenities. Mr. Grant shared the breakdown of the multiple family "pods" noting that the architecture, color and finishes will be different in each of the 17 "pods". The single family homes will be custom graded lots and Pulse is committed to saving as many trees as possible. In closing, Mr. Grant reiterated that there are enough occupants in this neighborhood to substantiate a park. Dennis Griswold, Landscape Architect representing Pulte Homes identified several key points from Pulse's perspective. This is one of the largest sites left in the City and they feel it's important to provide varied products on this parcel to create a diverse community. With that they want to provide parkland for the residents of this community which would accent the existing active space at the school. Pulse feels that facilities for younger children are needed along with walking paths and a connection to the school. They feel that these amenities will also benefit the residents to the east of the elementary and middle school as well. Mr. Griswold also noted that the playground at the school may not be available during the school year day and felt that the City may be relying too heavily on school facilities used primarily for organized play. The developer is hopeful that recreational amenities can be incorporated within this neighborhood because it will be bounded by busy roads. Member Markell asked about the accessibility from the street on the southeast portion of the site. Mr. Griswold stated they would look at the high water level to see what options may be possible. Member Vincent opined that the proposed land to be dedicated for park on this site is not closer for many of the residents than the school facilities. Mr. Griswold responded that although location may be an issue, having facilities within the development that would accent existing facilities would be of great benefit to the users. Member Vincent opined that open space would be more appealing and would prefer seeing passive use in this area since active space already exists close by. Vincent added that the question is whether there is a need for a park at this site since many other parks currently exist. Mr. Grant responded that many children cannot go to a park without their parents and they want to provide amenities that are within walking distance. Member Vincent stated that he was not motivated to accept land for park dedication and preferred a cash dedication to be used in an area where the need may be greater. Member Petersen noted that with the larger tract of proposed park land it could be left open to allow for natural trails at a later date. The small parcel, however, did not appear to have much usable value for parkland. Member Rudolph noted that there are several parks nearby with existing amenities. He expressed his concern for developing facilities on the larger parcel as proposed by Pulte because of the future need for parking which may change the "cozy playground" amenity the developer is hoping to create. Rudolph concluded that a park dedication on this site was not desirable and preferred a cash dedication. Mr. Grant asked if the Commission would consider a partial park dedication for 4 acres for a potential skating area/parking lot off Johnny Cake Ridge Road. This could be a fairly flat parcel that would allow for some park amenities. Member Vincent felt that the slopes may prohibit a parking lot in the area being designated and opined that this would be shoehorning the site. Vincent added that the developer may want to consider providing a play area on the site if they feel there is a need. Member Szott opined that the four acre site was essentially a private park for the lots that surround it. With respect to the larger parcel proposed for winter amenities, Szott stated that although the intention is good, it may be cost prohibitive to provide some of the amenities proposed given there are many of the same facilities within the Ya mile radius of this site. Director Vraa responded to the question relative to accepting a portion of the larger parcel for parks dedication by stating that although staff has not assessed that option, a recreational amenity such as frisbee golf may be something to consider. This would provide an opportunity for a facility not found in any of the other parks. The question was raised by some Commission Members as to the amount of interest this might generate within the community and could result in an adverse situation for the neighborhood. 14 Advisory Parks, Recreation and Natural Resources Commission Minutes of September 16, 1996 Meeting Page 4 Member Petersen and Markell suggested looking at the option of different park dedication layouts or consider other options to provide preservation of some of the land. Member Thompson opined that the City needs to get the most bang for their buck and supported a cash dedication. Mr. Grant noted that if the Advisory Commission was sincerely interested in accepting a parkland dedication in lieu of cash, they would look at some type of reconfiguration, however, if that is not the direction the Commission is headed, they would not expend any more time or resources to re-design the site. Member Markell asked what would happen to the land should it not be used for parks dedication. Mr. Grant responded that units may be placed on the area that is relatively flat, however, the steeper slopes would most likely be left as is. After further discussion. Michael Vincent moved and David Szott seconded a motion to make the following recommendations to the City Council relative to Rolling Hills - Pulte Homes: 1. This development shall be responsible for a cash parks and trails dedication. 2. The Tree Preservation Plan be approved as proposed with the following conditions: a. Tree Protective Measures (i.e. 4 foot polyethylene laminate safety netting) shall 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. b. The developer shall contact the City Forestry Division at least five day prior to the issuance of the grading permit to ensure compliance with the approved Tree Preservation Plan. c. The developer shall work with City Staff in an attempt to preserve additional significant trees located in areas within construction limits. Field reviews are recommended after roads are located and staked and prior to any grading or tree removal to identify any significant trees which could be preserved. 3. The developer shall raise and redirect the storm water drainage system (which is proposed to flow from the low area in the north vicinity of the single family development area to drainage Pond BP-3) to a new location running between single family lots 5 and 6 and between clubhouse lots 25 and 26. 4. Acknowledge that a performance guarantee will be required for this development. The amount of the performance guarantee will be calculated by City Staff following installation of the tree protection fence. (The amount of the performance guarantee will be calculated utilizing the total diameter inches of significant trees intended to be preserved within fifteen feet. of the grading limits). The performance guarantee will be collected as part of the Development Contract at the time of final plat approval. 5. An Individual Lot Tree Preservation Plan will be required for all single family residential lots with significant trees or woodlands remaining on them at the time of building permit application. 6. On-site ponding shall be the principle means of meeting water quality mitigation requirements. 7. Bond BP-3 shall be enlarged and constructed as a two-cell system, if possible. Those voting Aye: Randall Ahem, Michael Vincent, David Szott, Steve Thompson, and John Rudolph. Those voting Nay: Lee Markell and Daryle Petersen. The motion passed. I(D BUSINESS MOSQUITO CONTROL UPDATE Dave French and Jim Stark of the Metropolitan Mosquito Control Agency were present to provide the Commission with a yearly update of their program in Eagan. Dave French began by stating that there was a 26% budget decrease from 1995 which resulted in the loss of 1.5 regular full time staff members. Also as a result of the budget cuts, the MMCA is moving away from methoprene briquets and using pellets and liquid. w F ii0t4.~ MEMO city of eagan TO: ADVISORY PARKS COMMISSION FROM: KEN VRAA, DIRECTOR OF PARKS AND RECREATION C.J. LILLY, PARKS PLANNER DATE: JULY 16,1998 SUBJECT: COST ESTIMATE FOR JOINT PARKING LOT ADVENT UNITED METHODIST CHURCH BACKGROUND At the June Commission meeting, the Commission heard a request from Advent United Methodist Church to develop a joint parking lot. The lot would be designed to serve the parking needs of both Advent United Methodist Church and Patrick Eagan Park. A new entrance would be aligned with Northview Park Road. This location will enhance the safety of access to both facilities. The church currently has 84 parking spaces and is proposing 32 additional spaces on their property. The City would build an 84 car parking lot on park property, which would provide a total of 200 shared parking spaces. Patrick Eagan Park is programmed to have a future environmental education facility. A parking lot of this size should be adequate to satisfy the park's future needs. EXISTING CONDITIONS The proposed site at Patrick Eagan Park is currently being used as a tree nursery. The soil has been ideal for growing healthy trees for the City's parks. The cost estimate includes relocation of select nursery stock within the park. At this time an alternate nursery site has not been identified. DISCUSSION Staff has made a revision to the plan and eliminated a drive aisle. Attached is a revised layout plan. Based on this plan, a preliminary estimate for development has been made. The cost of the parking lot at Patrick Eagan Park is estimated in the range of $175,000-200,000. This estimate includes the following elements: 1. Relocate select nursery trees. 2. Storm water detention pond. 3. Provide erosion control. 4. Catch basins and storm sewers. 5. Concrete curb and gutter. 6. Bituminous parking lot paving. 7. Parking lot lighting. 8. Pedestrian trails. 9. Turf establishment. This estimate does not include engineering and design, soil correction or addition, material imports/exports to balance the site. Advent United is to prepare a proposal for cost sharing regarding this project. FOR COMMISSION REVIEW In the absence of a proposal for cost sharing, this is provided as background information. At such time as a proposal is received, the Commission can consider all the variables in determining the level of participation between the City and Advent United Methodist Church. 1 1 Ir_-`` 1' 1 ~ .Ot ~.-T - T.

LILLY, PARKS PLANNER DATE: JULY 17,1998 SUBJECT: DON GRANT OFFER TO SELL BACKGROUND/ISSUE Mr. Don Grant, of 1275 Towerview Road, has approached the City with an offer to sell his property. This parcel of land is located on the northern border of Moonshine Park. Mr. Grant's property is composed of four key areas (see attachments): 1. Landlocked parcel on west side of pond, wooded with steep slopes . 0.73 acres 2. Shallow pond, approximately 120 feet wide 0.75 acres 3. Home site, gently rolling land with mature trees 1.60 acres 4. LeMay Lake, good water clarity, excellent wildlife habitat 0.68 acres TOTAL AREA 3.76 acres Three real estate firms did a competitive market analysis for this property at the request of Mr. Grant. The following is a summary of their analysis: Real Estate Company High Average Low Burnet $270,000 $265,000 $260,000 Edina 269,000 264,000 260,000 Century 235,000 230,000 225,000 Based on this market analysis, Mr. Grant said he would be asking $240,000 for his property. He has tried to sell the landlocked property on the west side of the pond to his neighbor who abuts it but she has shown no interest at $25,000. PARK ANALYSIS Moonshine Park, preveiously known as Doneywood Park, was received by the City as parks dedication from the "By The Shores" plat in 1973. The park dedication is too small to develop. Like the Grant property to the north, it is composed of four key areas: 1. West side of pond, wooded steep slopes, poor access 1.25 acres 2. Shallow pond, approximately 120 feet wide 1.31 acres 3. Narrow park with access to LeMay Lake and Jurdy Road 1.80 acres 4. LeMay Lake, good water clarity, excellent wildlife habitat 0.24 acres TOTAL AREA 4.60 acres The residential area surrounding Moonshine Park is bounded by interstate 35E to the east and south, Lone Oak Road to the north and Pilot Knob Road to the west. The nearest playground facility is at Pilot Knob Park at the southwest intersection of Pilot Knob Road and Lone Oak Road. The 1982 Park system Master Plan suggested park expansion that would include play equipment and hardcourts to meet neighborhood needs and provide access to LeMay Lake. The City has been waiting for the Carl Olson property, located immediately to the south to develop for park dedication in order to expand the park. Mr. Olson was approached a couple years ago regarding a cash sale of ten acres. However, his price of $800,000 was too high for serious consideration. There are currently no development plans for the Olson property. The sale of the Olson property may become feasible in a shorter period of time if the proposed Ring Road concept is implemented. It would most likely cross 35E just south of Moonshine Park and would stimulate development of the Olson property. A park dedication of the Olson property along LeMay Lake would create an opportunity to connect Moonshine Park to a trail easement on the east shore of LeMay Lake which runs near the Farm Bureau building. This trail connection would benefit people walking from the munti- family homes on the north shore of LeMay Lake to gain park access. Project 743 Recently, the City Council received a petition from the two property owners adjacent to Mr. Grant for sewer and water service. This has been identified as Project 743. Attached is a memo prepared by Tom Colbert, Director of Public Works, which describes the project and costs associated with the project. Mr. Grant will be at the Advisory Commission meeting to present his proposal. The Commission should consider the value and benefits to the community if the property would be acquired. How would the property be used? How would it be accessed by the public? What would be the short term and long term benefits? How would the existing home fit the plan for the park? Is acquisition of this property more/less important than other land acquisitions? Does the parcel, because of its proximity to LeMay Lake, present an unusual opportunity and represent "good value"? FOR COMMISSION ACTION To make a recommendation concerning the proposal for acquisition of Don Grant's property. Donald & Claudia Grant 1275 Towerview Rd. Eagan, MN 55121 612-454-2758 June 19, 1998 Tom Hedges City Administrator City of Eagan 3830 Pilot Knob Rd. Eagan, MN 55122 Dear Mr. Hedges: On your recommendation I am submitting this proposal for your review and submission to the Director of Parks and the City Council. In 1974 The Cadence Corporation and Creative Housing, Inc. submitted the plat for the Donnywood Addition that bordered my property on the Southwest and South side of the addition number Two and Three. Three was as an easement to my West property line. I agreed to withdraw my objection to delay the project on the following conditions: Access to my property with my motorized tractor over outlot from Quarry to Quarry Lane and outlot Quarry Lane to the Southwest of my Property line. The developer agreed to fill the North end of the pond on Vanmeter and Grant properties to create a 30 foot road access with project fill giving a vehicular access to the West end of my property. The project was approved and the outlot was installed. The developer never completed the land fill, thus leaving the west end landlocked. The failure to fence, maintain and complete the walking paths has allowed residents to dump yard waste including tree limbs on both park and Grant property. In July of 1969 the Eagan Town Board and Engineer Bob Rosene (in conjunction with Master Storm Sewer Plan and Development of Rauenhorst Industrial Property) approved the installation of an inlet and outlet on Lemay Lake. To eliminate a possibility of erosion with a higher lake level the Township requested permission to reslope the east shoreline of the Grant Property. This request was granted September 1969, but no easements were given. Upon construction of Highway 35E , a new inlet to Lemay Lake was installed by the Minnesota Highway Department with two holding ponds on the east side of 35E. This created minor problems with the rainfall of 18" in 1986. Upon development of Eagan Town Center Promenade, additional water flow was created by 1997's eight inch rainfall which caused flooding up to 24 feet on the East shore that took two week to recede. This in turn killed the grass and left 20 feet of softened shoreline, which affected five old growth trees. Each subsequent rainfall of 2" or more contributes to more softening and more erosion. As new Promenade buildings and developments are approved this will increase the problem. On site inspection for high water and softening was viewed by councilman Wachter and your Engineering Department. Recommendations to correct existing problems of flooding and shore erosions: A. 24 inch berm/fill with gravel at water's edge and back to a necessary distance for ground level on the 280 feet of shoreline. B. Increase exit outlet size to allow for present and future levels. C. City of Eagan to fill pond 30 feet wide with culvert for water flow giving land access to landlocked property for development on south of Grant property line. D. City of Eagan to acquire landlocked property which is about 200 x 300 feet or 1 1 /2 acres and join this to existing Park property to correct City failure to follow up developers promise to fill access. E.Acquisition of Grant property in total. This would allow/eliminate/enhance the following: 1. No need to build up shoreline. 2. No need to connect land locked property except for a possible walking bridge in center of "wildlife park". 3. Eliminate any need to fence park and private property. 4. Provide the city a "shoreline easement" on their own property and I believe the last easement not acquired on Lemay Lake. 5. An opportunity to develop a usable wildlife park that could be doubled in size, a lake level picnic area of 263 feet on Grant frontage combined with 550 feet of park land for a total to 813 feet of lake shore (about 6 acres). This would allow completion of walking paths that will connect with existing and proposed paths. Future acquisition of the Olson property on the south side of Lemay Lake either by purchase or condemnation (Eminent domain) will provide continuation of paths on South and East side of Lake. Not only will this provide for a usable park in the NW 1/4 and SW 1/4 of Section 10, (that is now without a usable park), but will tie into the five year bridge plan proposed to the North of Yankee Doodle and will provide access to the Eagan Promenade Expansion. 6. Provide an easement from Towerview on the North thus not locking out access to existing Park property and providing an existing house and garage capable of use as Park Maintenance or daily or weekly hostel camp out or church/group gatherings. 7. We have had market evaluations by five realestate brokers in the past three weeks to explore sale of our property. As 4.78 is much to maintain for just the two of us, we have always desired to keep it intact as one parcel, but believe the park acquisition would be a wise and superb move by the city at this time because it is needed, available and good for the City and it's Citizens. I have provided maps of the proposed areas and our property for your on site review at this time. Thank you. Sincerely, 4e~ Donald E.

This property is referenced as Parcel 041-31 located in the northwest quarter of Section 10 along the western shore of LeMay Lake. The attached topographic map shows the location of this property. On May 5, 1998, the City Council received a petition from two of his adjacent neighbors requesting the preparation of a feasibility report to evaluate the scope, cost, financing and scheduling for extending and installing City sanitary sewer and water facilities in this area. The Engineering Division has retained a consulting engineering firm to assist in the preparation of this study. Although Mr. Grant did not petition for this improvement, service to his property will be included in the study since he would be the lone remaining parcel without City sewer and water. Currently, all three property owners are on private well and septic systems and share a private drive with cross easements and private maintenance agreements. Due to the unusual configuration of the property lines, the location of the homes and related out-buildings along with the steep and wooded topography, the ability for these parcels to subdivide is limited at best. Also, the lower topography would require the installation of a small sewer pump. These factors all result in a limited number of building sites available to finance the cost of these public utility extensions. Preliminary cost estimates indicate that the total cost for these utility extensions would be in the range of $100,000 to be shared proportionately between the benefiting properties. Please let me know if additional information would be helpful in the City's consideration of Mr. Grant's request regarding acquisition for possible park purposes.

TO: ADVISORY PARKS COMMISSION FROM: RICH BRASCH, WATER RESOURCES COORDINATOR DEPARTMENT OF PARKS AND RECREATION RE: RESULTS OF WATER RESOURCES EDUCATION SURVEY-FOLLOW-UP DATE: JULY 15, 1998 In 1994, the City of Eagan began participating in a cooperative water resources education program with Dakota County to raise the level of knowledge of residents in northern Dakota County regarding non-point source pollution control. In June, 1994, a telephone survey was conducted to establish a baseline for level of knowledge and behavior profiles prior to initiation of the county-wide program. In October, 1997, a second survey was conducted to provide data to compare with the data collected during the 1994 survey and to compare level of knowledge an behavior profiles in individual cities with those for the County as a whole. Water resources staff presented the results of this assessment to the Commission at the March 1998 monthly meeting. Missing at the time of that meeting was a comparison of survey results among only City of Eagan residents, focusing on residents within the Fish and Schwanz Lake watersheds within which relatively intensive public education efforts have been conducted during the last several years. Staff indicated that this analysis would be conducted and presented to the Commission at a later date. That analysis has been completed and the results are attached for the information of the Commission. I think you will agree that the results are exceptional!! Result highlights include the following: • 18% (an increase from 44% to 62%) more respondents knew where water that runs off their property goes. • When asked, "Once runoff from your property enters a storm sewer or catch basin, where does it go?", the inability to answer the question dropped in half, from 48% being unsure to 24%. The number of respondents answering either "holding pond" or "area lake" doubled. • There was an increase of 26% (from 32% to 58%) of respondents who knew that water entering storm sewers or catch basins is not chemically treated or purified. • Awareness of the CLIMB Theatre play "Toadilly Turtle" tripled in the two year period (from 7% to 21%). • There was an increase of 10% in the number of survey respondents who could define the term "watershed". • There was an increase in the number of respondents who acknowledged a link between surface and groundwater. It should be noted that credit should go to the Dakota County Environmental Education Program for providing grant funds to support the City's education efforts and for disseminating common messages county-wide that further reinforced our efforts.

Page 4 Cl' city of eagan MEMO TO: ADVISORY PARKS COMMISSION FROM: KEN VRAA, DIRECTOR OF PARKS AND RECREATION GREGG HOVE, FORESTRY SUPERVISOR DATE: JULY 16,1998 SUBJECT: STORM DAMAGE SUMMARY - TREE HEALTH UPDATE Now that a fair amount of time has passed since our last storm, staff has had a chance to make some observations of storm damage on trees. In an effort to turn a negative into a positive we must learn from this disastrous event. In this memo I would like to not only provide a review of what happened, but also share suggestions as to how to minimize storm damage in the future. WHAT HAPPENED TO US! Since May 15`' the City of Eagan has been hit by at least four major storms, (May 15, May 30, June 15, and June 27). High winds associated with each of these storms caused some type of tree damage. Probably, most of the damage occurred from the May 30 storm. Storm clean up began the morning of Saturday, May 16, and is still occurring to some degree today. Some estimates have figured the number of trees damaged or destroyed from these storms totals at as much as 4,000 trees. WHAT WE OBSERVED! Natural disasters provide for excellent opportunities to observe and learn. Here is a summarization of what forestry staff observed following storm damage. 1. "Tall native trees", (older, naturally occurring trees in open or wooded areas) These trees were damaged by large limb branch breakage or by complete tree blow-down. In other words, these large trees stood as long as they could until extremely high winds either cracked large limbs, causing them to fall off, or if the branch angles were strong, the tree crown held together long enough until the tree basically uprooted and tipped over. An example would have been a large 30" oak tree that has had the entire tree, root system and all uprooted. 2. "Landscape trees", (younger trees installed into yards or park areas). These trees succumbed to a different fate. Because of "human factors" many of these trees met a premature death. The number one reason was planting depth; the trees were originally planted to deep, sometimes as much as six to eight inches too deep. This incorrect installation initiates several negative situations, girdling roots, basal trunk rot, and stem cankers to mention a few, all of which result in weak spots on the lower trunk causing the tree to "topple" during even smaller wind gusts. Many of these trees also had very poor tree architecture, or crown shape and/or condition. Poor pruning practices, no crown maintenance at all left tree crowns in a very vulnerable condition. Many branch angles had "included bark", (the branch crotch grows inward, into the trunk, versus outward where a clean healing process would take place). Branches with included bark are very prone to "disassembling" during windstorms. 3. "Construction trees", (trees of any age class which have been exposed to some type of construction activity). Typically, what we saw here were larger trees, preserved during construction, but had been negatively impacted throughout the process. Roots were cut or smashed, soil in root zones was compacted, tree trunks or branches were damaged, or trees were fragmented from larger stands leaving them vulnerable from wind and other environmental conditions. These trees are easy prey for high winds as their necessary anchoring root systems have been cut to a fraction of what they naturally were, or the tree is altered into a condition where it is no longer able to withstand normal storm conditions. 4. "Conifer trees", (spruce and pine trees). Many of these evergreen trees are not native to our area. They typically have shallow root systems, even in their natural forest environment with sandy-loam soil. But here with our hard clay soil they have even shallower root systems. Many uprooted trees had root depths measured to as shallow as 9" to 12", not much support for a 35 foot tall tree. Full crowns of these trees serve as heavy sails in wind storms, creating a situation where they can easily blow over if they don't have adequate anchoring support from their root systems. WHAT WE LEARNED! Most foresters have known this, but now it should be even more obvious, that even though trees are the largest living things on earth, that they are relatively fragile. Alterations in their natural environment can have devastating affects. To put it simply, as we develop and re-landscape urban areas we take trees out of their naturally occurring environment and ask them to perform as if they were still in that environment. What we need to do is re-establish, to the best of our ability, that "natural environment". We've learned that correct planting depth is critical for tree survival. A tree planted even a few inches too deep will grow in a stressed condition, making it vulnerable to many problems. We've also been reminded that creating a proper tree crown structure at a young age can positively affect the eventual life of the tree. The time to "shape" a tree is when the tree is very young and actively growing. This means that the tree should have a straight central leader, branches should not be crowded or crossing over each other, pruning cuts should be made at the appropriate place (branch collar) and during the appropriate season (typically the tree's dormant season). We've learned that, in our area especially, tree root zones are very shallow and wide spreading. Trees isolated from a wooded setting cannot withstand high winds because their root systems have not been required to grow out to distances needed to anchor a lone tree. They have basically depended on the tree neighbors for structural support. We need to preserve larger groups of trees and not disturb the natural forest floor. It has been made painfully obvious to us that construction activity can have both short-term negative affects as well as long-term negative affects on trees. Even years after the bobcat or backhoe has left the site, trees can begin showing the consequences of poor construction methods. Crown dieback, trunk cankers, and root diseases begin to appear, all which add stress to the tree, making it weaker and more vulnerable to storm damage. We've learned that species diversity is always the right way to go. Environmental conditions affect different tree species in different ways. By increasing the numbers of tree species within our area, we will decrease the likelihood that severe storm damage will occur. WHAT WE SHOULD DO NOW! The obvious answer here is to begin replanting trees. Work has already begun on a."city-wide" tree reforestation program. The goal will be to wisely replant trees on both public and private property within Eagan. Here are a few pointers for us all to keep in mind as we "re-green" our city. 1. Be patient. Trees are relatively long-lived, slow-growing plants. Today we are able to enjoy large mature trees because someone, many years ago planted or preserved them. Don't expect to get the large trees that we've lost back overnight. Remember, trees that grow extremely fast, have weak and/or brittle wood, prone to early damage or death. 2. Plant native tree species in a more naturally occurring environment. This can be easily achieved by cluster planting two or more trees into an organically mulched area. Better yet, plant an understory of shrubs, perennials, or native grasses under and within the new trees. 3. We must plan for both species and age diversity in our new urban forest. We all remember what we learned from the Dutch-elm disaster, that is to not plant large monocultures of trees. Contagious diseases such as Dutch-elm disease can have far reaching and devastating effects on these singular tree populations. We need to plant many species of trees. Also, we must not do all of our new reforestation at one time. To ensure both a healthy and a more aesthetically pleasing urban forest we need to optimize tree age. In other words, plant some trees now, some trees next spring, some trees next fall, etc.. 4. Practice correct tree preservation techniques. Protect the trees root zone, which on many trees extends out to a distance of two to three times the height of the tree. Keep construction equipment off of this area. OTHER TREE RELATED CONSEQUENCES! 1. Unfortunately for us these storms hit at the exact wrong time of year, OAK WILT season. The old rule is, to prevent oak wilt, don't prune in April, May, or June, well the storm did plenty of "pruning" during this exact time. This basically set the forestry division on stand- by alert for near future occurrences of oak wilt disease. I've summarized below statistics relating to both oak wilt and Dutch-elm disease for 1998 (until July 10) and compared them to 1997 numbers. Oak Wilt Dutch-elm Disease 1998 1997 1998 1997 Sites Trees Sites Trees Sites Trees Sites Trees 24 39 24 55 15 28 28 62 The data to date indicated that even with this years storms occurring during oak wilt season, we have not yet seen the "explosion" of oak wilt infections that most people feared. However, we are not "out of the woods" yet. New infections from oak wilt can take up to 45 to 60 days for symptoms to appear as wilting leaves. Forestry staff is diligently monitoring oak tree crowns in known oak wilt areas. Even Dutch-elm instances are not as high as last year's numbers. Both diseases may be down somewhat due to the relatively good year for plant growth (aside from the physical abuse from the storms). Spring came early, rainfall has been just about right, and up until last week temperatures have been fairly moderate. All of these conditions have allowed plants to grow rather easily. 2. Forestry staff has since May 16`'', received many, many calls related to storm damaged trees. Most of them deal with how to repair damaged trees or information on how and when to replant new trees. To summarize our responses to these types of questions, I've included a copy of a reply to a question from the Mr. Fixit column in the Star Tribune. The reply was written by Mr. Ken Hollman, Community Forestry Coordinator, Minnesota DNR. (See MEMO below). MEMO To: Karen Youso, Fixit Column, Star Tribune From: Ken Holman, Community Forestry Coordinator, Minnesota DNR Subject: Response to leaning tree concerns Date: June 17, 1998 Question: Many of the trees left standing after the May 30' windstorm are leaning to one side. Is there any reason to worry about this? Is there a greater chance that these trees will come down in future storms? Will these trees suffer any ill effects? `~a Mr. Holman's response: In answer to all your questions, YES! Trees that survived the May 30`' storm should be carefully inspected. The tree's anchoring roots have been partially severed and, perhaps, a large limb was cracked but has not fallen. If the tree is growing over a house, driveway, sidewalk or other target, it can pose a serious hazard. Given the space, a tree's root system will grow out two to five times the spread of its branches, with over 90% of the roots found in the upper one to two feet of soil. While root damage may be the result of old age or the shear force of the wind, typically it can be traced back to some form of construction damage: new or replaced sidewalks, curbs, driveways or underground utilities. Poor root and trunk structure is also caused by planting a tree too deep or by roots themselves girdling the base of the trunk. Branch failure is another, story: improper pruning, topping of the crown or narrow branch to trunk connections with "included bark", all can result in very large limbs being ripped out of the tree in 100 mph winds. Many more damaged trees remain than those removed. Homeowners and communities will be dealing with the survivors for many years. My best advice is to have your tree(s) inspected by a competent arborist, certified by the International Society of Aboriculture. Your City Forester or DNR Area Forester can refer you to an arborist who works in your neighborhood. Ask anyone you are considering hiring for their qualifications: are they insured, bonded and willing to provide references? Avoid the "weekend-pickup-and- chainsaw-logger" going door-to-door. Subject to approval ADVISORY PARKS COMMISSION EAGAN, MINNESOTA MINUTES OF REGULAR MEETING OF MAY 18,1998 The regular meeting of the Advisory Parks and Recreation Commission was called to order on May 18, 1998 with the following Commission Members present: Terry Davis, Barbara Johnson, Bonnie Karson, George Kubik, Lee Markell, Daryle Petersen, and John Rudolph. Members not present included Jerry Farlee, N. Mark Filipi and Michael Vincent.. Staff present included Ken Vraa, Director of Parks and Recreation; Dorothy Peterson, Superintendent of Recreation; Paul Olson, Parks Superintendent; CJ Lilly, Parks Planner/Landscape Architect; Rich Brasch, Water Resources Coordinator; Gregg Hove, Forestry Supervisor and Cherryl Mesko, Secretary. ENV George Kubik moved, Terry Davis seconded with all members voting in favor to accept the agenda as presented. George Kubik moved, John Rudolph seconded with all members voting in favor to accept the minutes of the regular meeting of April 21, 1998 as presented. Items highlighted by Director Vraa included the May 4 public meeting to discuss trail clearing in the winter, near completion of weed spraying the major park areas, play structure installation at River Hills Park, completion of the 4-year prairie restoration management plan at Thomas Lake Park, distribution of the Summer/Fall brochure, 200 youth participants at the annual baseball clinic, 300 youth participants at the annual softball clinic, the beginning of EAA summer sports, the slight decline in sand volleyball team registrations and the first year of Cricket being played at Walnut Hill Park. Member Markell asked how many hours of work are provided by the Sentence to Serve work crews. Hundreds, Superintendent Olson responded. Member Kubik commented on the successful Arbor Day celebration. Member Petersen asked if responses had been compiled relative to the trail clearing survey. Director Vraa responded that the Public Works Department is compiling that information. "MMOMM, There were no consent items for the Commission to review. DEVELtSTIME NJ` LEXINGTON 2ND ADDITION - HOME DEPOT Coordinator Brasch provided a brief background of this item noting that Home Depot, U.S.A. is proposing to build a 132,000 square foot retail store on a site located west of Lexington Avenue at Northwood Parkway, south of the USPS bulk mail facility in the SE 1/4 of Section 10. Advisory Parks Commission Minutes of Regular Meeting of May 18, 1998 Page 2 Relative to water quality, Brash noted that this development is located in the LeMay Lake watershed just north of Eagan Promenade and east of 35E. Runoff from this site will travel through a number of already constructed nutrient traps before reaching LeMay Lake, which is one of the City's seven Class I water bodies. The wetland inventory for the site shows two wetland complexes; a .62 acre Type 2/6 in the northcentral portion of the site and a 3.25 acre which occupies much of the southeast portion of the parcel. The developer is proposing to fill all of the .62 acre wetland (16% of the wetland area on the site).Given the location of the wetland near the central portion of the site, the guided land use and the fact that less than 20% of the jurisdictional wetland area on-site will be filled, and Brasch noted that an unavoidable impact funding would seem reasonable. Per the Minnesota Wetland Conservation Act, Brasch explained that a minimum of 1.14 acres of additional wetland credit must be generated to meet the mitigation requirements. The developer proposes to use a rough graded area just south of, and contiguous with the large wetland in the southeastern comer of the site. After further discussion, Lee Markell moved, Barbara Johnson seconded with all members voting in favor to make the following recommendations the City Council relative to Lexington 2°" Addition - Home Depot: 1. This development shall be responsible for a cash parks dedication and a cash trails dedication. 2. The Tree Preservation Plan shall be approved as proposed with the following conditions: • The applicant shall install sixteen (16) Category B mitigation trees, (or an equivalent combination of Category A or Category C trees). These 16 mitigation trees are in addition to any City of Eagan landscape requirements. • Tree Protective measures (i.e. orange fabric silt fence or 4-foot polyethylene laminate safety netting) shall be installed at the perimeter of the Critical Root Zone of significant trees/woodlands to be preserved. No grade change, construction activity, or storage of materials shall occur within this fenced area. • The applicant shall contact the City Forestry Division at least five days prior to the issuance of the grading permit to ensure compliance with the approved Tree Preservation Plan. • Grading plans for the utility easement areas shall be reviewed by the Forestry Division for tree preservation mitigation. 3. The developer shall meet water quality mitigation requirements entirely through on-site ponding. The pond should have a minimum wet volume of 2.3 acre-feet and shall meet the City's Detention Basin Design Standards. 4. The wetland mitigation plan dated May, 1998 should be approved, assuming the allowable development intensity allowed on the site will be decreased by the City. 5. The upland buffer around the remaining jurisdictional wetland (Pond DP-6.2) should be extended a minimum distance of 30 feet back from the delineated edge of the wetland. 6. It is recommended that the parking be reduced by 5-10% with the removal proposed on the eastern portion of the site to allow for the 30 foot wetland buffer. BLACKHAWK ACRES 5TH ADDITION - MENDOTA HOMES, INC. Director Vraa introduced this item noting that Mendota Homes is requesting a Preliminary Subdivision to create four lots for the construction of two two-unit townhomes on property currently platted as Outlot A, Blackhawk Acres 2nd Addition east of Robin Lane. Advisory Parks Commission Minutes of Regular Meeting of May 18, 1998 Page 3 Coordinator Brasch explained that this development is adjacent to Pond AP-27 and in drainage basin A downstream from Blackhawk Lake. Because the wetland associated with Pond AP-27 is large and a designated recreational water body, an ungraded, un-maintained buffer extending 30 feet back From the edge of the wetland is being recommended. The revised grading plan, however, shows filling of about 300 square feet of the jurisdictional wetland. This issue for Commission consideration is whether to recommend to the City Council that the 30 foot wide buffer be required, which would cause significant alteration of the development plan, or omit the buffer condition. Forestry Supervisor Hove stated that there are 17 significant trees identified in the tree inventory. The application as submitted will result in the removal of three significant trees (40%) which is less than allowable limits, therefore there is no required tree mitigation The representative from Mendota Homes stated that they are proposing to build two, two unit townhomes. They are hoping to provide a transition between the two buildings and by doing so it places one of the buildings within the 30 foot upland buffer area. The only way to prevent that would be to connect the two buildings. Member Markell asked what the land use was between the two buildings. The developer responded that it was open space and that by separating the 4 units into two buildings it provided a logical transition to the adjacent single family properties. Several options were discussed relative to moving buildings to the west to maintain the buffer zone as well as leaving the buildings where they are. Coordinator Brasch interjected that a combination of landscaping for wildlife habitat and native grasses could be incorporated into the plan if the Commission allowed the buildings to stay where they're currently located. Member Kubik thought it would be appropriate to look.at tis type of landscaping as long as the developer worked closely with staff to make sure the area was protected as much as possible. Member Davis added that by keeping the area in natural grasses it would catch the run-off from the home before getting into the wetland. After further discussion, Daryle Petersen moved, Terry Davis seconded with all members voting in favor to make the following recommendations to the City Council relative to Blackhawk Acres 56 Addition - Mendota Homes, Inc.: 1. This proposal shall be subject to a cash parks dedication and a cash trails dedication. 2. The Tree Preservation Plan shall be approved as proposed with the following conditions: • Tree Protective measures (i.e. orange fabric silt fence or 4-foot polyethylene laminate, safety netting) shall be installed at the perimeter of the Critical Root Zone of significant trees/woodlands to be preserved. No grade change, construction activity, or storage of materials shall occur within this fenced area. • The applicant shall contact the City Forestry Division at least five days prior to the issuance of the grading permit to ensure compliance with the approved Tree Preservation Plan. 3. The development shall be subject to a cash dedication in lieu of on-site ponding. 4. The developer shall work with staff to preserve an upland buffer extending 30 feet back from the edge of the jurisdictional wetland. 5. The developer shall bear the cost of vegetating the upland buffer as approved by staff and will advise potential owners that the area is to be maintained as such. Advisory Parks Commission Minutes of Regular Meeting of May 18, 1998 Page 4 OLD BUSINESS TEENS Director Vraa noted that at the April 20 Commission meeting the issue of a teen center was brought forward with a proposal from the YMCA and another proposal presented by Michael Vincent. Vraa reviewed the highlights of each proposal, the memo from Chief Gaegan outlining existing centers in other communities, the memo from Building Inspections relative to a teen center at the Civic Arena, a memo from Jerry Farlee regarding the Recreation Sub-committees review of this issue and the concerns identified by the sub-committee. Director Vraa stated that staff is looking for input and direction from the Commission. Member Kubik identified several questions he had relative to the Civic Arena proposal. He asked to see more detailed layout drawings, asked for clarification on how security would be handled, how staffing would be funded, further clarification of conflicts between arena events and the center's use and also suggested that alternate locations be considered. Member Johnson expressed her concerns for the location as well and concurred that other options should be explored. She noted there were no provisions for cleaning/trash removal and wondered what the budget impact(s) would be relative to code issues. Another concern was a clear understanding of who would be coordinating the Civic Arena teen proposal and who would be responsible for paying the bills and making sure that everything was funded appropriately. Johnson also noted that the cost to put in activities would need to be addressed as well. Member Petersen commented that the Recreation Sub-committee met on May 3rd and had invited the YMCA to participate. The Y did not attend and Petersen asked if they'd met with any of the youth groups to solicit their input. Superintendent Peterson responded that the Y had not met with any youth groups to her knowledge. Member Davis felt there needed to be a clarification of the $55,000 cost associated with the Civic Arena proposal. The YMCA is looking for a $75,000 contribution from the City, however, it doesn't appear that the teens that have been meeting are interested in their location. Davis suggested that the Y be encouraged to talk with youth groups. He felt that the Municipal Campus was a great central location and the Civic Arena allows for alternate uses by other organizations. Davis suggested that a workshop setting may be a better way to discuss this issue further. Member Johnson asked if more teens could be brought into this workshop session for their feedback Member Karson concurred suggested that it would be important to hear from a more varied group of teens. Member Rudolph suggested more dialogue with the outside partnership to clarify the funding of the Civic Arena proposal, It was the consensus of the Commission that a workshop be scheduled which would include an expanded audience of teens to better review this issue. Superintendent Peterson suggested that Commission Members attend the next teen meeting scheduled for May 30th. Advisory Parks Commission Minutes of Regular Meeting of May 18, 1998 Page 5 SKYLINE DISPLAYS Director Vraa recapped the Commission's visit to the site with Skyline Displays. The developer was very receptive to the ideas presented to them including removing the garden plots, moving the proposed amphitheater and re-working the roadway and ponding needed on the site. They are proposing to return to the Commission with revised site plans and elevations at a future meeting. Member Johnson asked if the responsibility for maintenance had been identified. Director Vrarl., stated that had not been addressed as yet. Member Davis asked if there was consensus.that this is an acceptable spot for a park. Vraa responded that the developer has been getting feedback from the Commission solely to determine if the concept would be possible. 'Member Davis reiterated his concern that the City not create unrealistic expectations for the developer should the determination be made that this is not a preferred location for a park and a cash dedication is required. Member Markell stated that the developer is aware that this is a preliminary concept being explored. There were no new items for the Commission to review. WALDEN HEIGHTS UPDATE Parks Planner Lilly noted that the development plans for Walden Heights Park are proceeding as planned. He shared pictures of the site's existing condition and then reviewed the location of the trail. Director Vraa added that staff is planning to grade and seed the site this year with the balance of the park construction scheduled for 1999. ICE POLICY Coordinator Brasch provided a brief background and introduced Brian Jensen, a Burnsville High School senior working on this project as part of a school project. Mr. Jensen explained that he had conducted the background research and drafted several policy alternatives as a project for an advanced placement class in government policy. The Natural Resources Subcommittee met to provide direction and feedback. Brian provided a very extensive and thorough review of his research and proposal for ice safety warning including bodies of water without public access points, bodies of water with public access points and unnatural conditions caused by the City. He then reviewed the purpose and need for a policy, a proposed policy, procedure and responsibility for such a policy. One of the suggestions brought forward was a warning policy for those bodies of water that contain formal public access points. It was felt that by placing general signs warping of the potential danger at public access points the public would be alerted to the potential of injury or death which would allow them to decide whether to proceed at their own risk. Bodies of water that do not provide public access points would have no signage posted. Advisory Parks Commission Minutes of Regular Meeting of May 18, 1998 Page 6 Member Petersen commended Brian for the extensive background work he had done on this project noting that the Natural Resources Sub-committee had met twice with him. Petersen noted that the policies proposed are an accumulation of good work and reflect the discussions that occurred. He continued that the Commission will need to decide which policy to take forward to the City Council. Petersen opined that recommending no signage seems ta.be in the best interest of the City. Members Johnson and Rudolph agreed with the recommendation for a no sign policy. Member Davis asked if this issue was discussed with the City attorney. Brian responded that the City attorney was provided with a copy of the policy but had not responded to date. Member Davis opined that a legal opinion should be included prior to sending a recommendation to the City Council for consideration. Member Karson added that by posting signs it could open the City up to "detrimental liability" and also supported a no sign policy. After further brief discussion, Daryle Petersen moved and Barbara Johnson seconded a motion to recommend to the City Council that a "no sign policy" for ice safety be approved pending review by the City Attorney. Member Kubik again suggested waiting until after the City attorney had reviewed this issue before proceeding to the City Council. The motion was called. Those voting Aye included Bonnie Karson, Daryle Petersen, John Rudolph and Barbara Johnson. Those voting Nay included Lee Markell, George Kubik and Terry Davis. The motion carried. Commission- Members concluded with their thanks to Brian for an excellent report. ! ,KU R BL]S SS AND`; There were no Other Business and Report items for the Commission to review. ROUIW TABLE Member Markell suggested prioritizing open space funds for future consideration. Member Davis asked for an update of the playground that was encroaching upon City property. Director Vraa reported that it had been removed within the time frame set by the City. AD~QURNMI~T With no further business to conduct, George Kubik moved, John Rudolph seconded with all members voting in favor to adjourn the meeting. The meeting was adjourned at 9:40 p.m. Secretary Date Subiect-to Approval ADVISORY PARKS COMMISSION EAGAN, MINNESOTA MINUTES OF REGULAR MEETING OF JUNE 15,1998 A regular meeting of the Advisory Parks Commission was called to order at 7:00 p.m. on June 15, 1998 with the following Commission Members present: Terry Davis, Jerry Farlee, N.

I Y 1?Q NT 07 SA S There were no development items for the Commission to review. OLI Us1N s TEENS Member Rudolph explained that a workshop was held with Commission Members, staff and teen representatives prior to this meeting. The meeting was a brainstorming session in which the teens were looking for direction and/or support for a teen center proposal. Director Vraa added that questions asked previously by the Commission were again raised. It was noted that the proposed layout for the mezzanine at the Civic Arena resulted in a preliminary estimate of $95,000. Although the teens did not feel they needed exclusive use of the mezzanine space, Commission Members expressed concern for conflict with other activities, additional staffing that may be needed, maintenance and whether alternate sites should be considered. The group also reviewed what other communities are doing as well as the budget implications of the Civic Arena proposal. It was again noted that the teens prefer this more central location and felt that the inclusion of middle school age students was important. The teens expressed their willingness to move forward to solicit financial support for a teen center but in order to approach potential donors felt that they needed the verbal support of the City first. It was noted that Rosemount provides teen events rather than a teen center and the youth expressed their interest in finding a location in Eagan for socialization and/or a collecting spot to move onto other events. Member Rudolph opined that the Civic Arena is a good proposal and perhaps the best location but expressed concerns for the capital expenditures. Other Commission Members expressed similar concerns however, felt that in order for the teens to proceed forward to solicit financing they needed to identify what they were soliciting funds for. Member Davis opined that it was pre-mature to move forward to the City Council with a recommendation. He suggested that a more formal proposal be prepared including the goals, mission statement, etc. for this request. Davis added that he wanted more information before proceeding forward with a recommendation to the Council. Advisory Parks Commission Minutes of Regular Meeting of June 15, 1998 Page 3 Member Vincent commented that it isn't a question as to how much money it will cost at this time, rather a recommendation to the City Council as to a preferred site for a teen center. The funding, if the teen center is to move forward at the Civic Arena, would come completely from fund-raising efforts by the teens. Member Davis reiterated his desire to have a formal request, in writing, to proceed with a recommendation. Member Rudolph suggested that that information might not be obtainable until finding is better defined. Member Petersen added that this is merely a conceptual proposal at this time but supported the location at the Civic Arena. After further brief discussion, Barbara Johnson moved and George Kubik seconded a motion to ask the City Council to approve the concept of the use of the Civic Arena mezzanine for a teen center so that the teens who have been involved in this project can move forward to solicit funding. hose voting Aye included Jerry Farlee, N. Mark Filipi, Barbara Johnson, Bonnie Karson, George Kubik, Daryle Petersen and John Rudolph. Member Davis voted Nay because he did not feel prepared to present a recommendation to the City Council and Member Vincent abstained because of his involvement with the initial proposal. SKYLINE DISPLAYS This item was deferred to the July 20, 1998 Commission meeting. ADVENT UNITED METHODIST CHURCH Director Vraa provided a brief background explaining that the church is located immediately north of Patrick Eagan Park and is proposing an expansion to their building. The church is proposing to close the current entrance to the church from Lexington Avenue in favor of an access that aligns with Northview Park Road and Lexington Avenue. This concept was discussed between the City and church several years ago after the McCarthy property was acquired, Vraa added. It was noted that the church was looking for a cooperative effort to meet their expansion needs by proposing a shared parking lot that could accommodate the church's needs as well as the City's future needs for Patrick Eagan Park. Director Vraa noted that there currently is no master plan for Patrick Eagan Park nor an assessment as to how this shared parking would work. Sara Kelsenberg, architect representing Advent United Methodist Church explained that the church saw the opportunity to link their expansion needs with the needs for Patrick Eagan Park and would like to create a linkage/transition to the park. The also saw the benefit of conceptually moving the shared access onto park property. Member Petersen asked if the 32 parking spaces shown on the northwest portion of the site would be developed at the same time as the other parking stalls. Noting that the parking was close to residential, Bruce Maus, Building Committee Chairman noted that the church wanted to be a good neighbor and will share plans with all surrounding properties. Mr. Maus reiterated that the plans being presented were conceptual only. They are intended to solicit feedback from the City as to the viability of shared parking and access. He added that the access issue would need to be addressed with the County as well. Daryle Petersen said he saw moving the access and sharing parking to be beneficial. He suggested that the parking lot be made smaller and that more green space be provided between houses and parking lot(s). Advisory Parks Commission Minutes of Regular Meeting of June 15,1998 Page 4 Member Rudolph asked several questions including how conflicts of use would be handled, what is the impact to storm water, who is responsible for parking lot maintenance/plowing, and what would happen to the existing nursery. Since there is not a park plan in place, Rudolph was concerned about proceeding with this plan. Member Kubik explained that pursuing options would not necessarily be an endorsement but an opportunity to jointly explore opportunities. Following brief discussion, George Kubik moved, Michael Vincent seconded with all members voting in favor to ask staff to work with Advent United Methodist Church to explore shared access and parking options. POTENTIAL USE OF QUARRY PARK BUILDING Superintendent Peterson explained that an inquiry had been received concerning the availability of week-end meeting space for Somali families. It was noted that since many Somali children were born in refugee camps, they have no knowledge of traditional Somali ways. The group making the request wishes to provide positive male role models to youth who would otherwise not be exposed to their culture through an older male family member. Peterson then reviewed the issues relative to the potential use of Quarry Park. She noted that the Quarry shelter was seasonably available on week-ends, however would not be during the winter skating season. There were also questions as to whether the 6 month time frame would be sufficient for the Somali community and whether or not it was within the Department's mission to play a role in assisting the Somali community at this time. Member Karson empathized with the plight of the Somalis and felt that this would be an appropriate request to grant. She added that she would like to see the City reach out to this community for six months. After further brief discussion, Barbara Johnson moved, George Kubik seconded with all members voting in favor to direct staff to negotiate an appropriate fee to allow the use of Quarry Park shelter building for use by the Somali community for six months. It was noted that this approval to use Quarry shelter is not a precedent for future requested use by other groups. Parks Planner Lilly brought the Commission up to date on the development of Walden Heights Park. He noted that the City's engineering department is completing some of the staking in preparation for Enebec to do the grading on the site. Lilly added that the grading work should be done by the end of July. Member Rudolph commented that there are several clusters of trees and thought it appeared that grading was occurring in the drip line. Forestry Supervisor Hove reassured Member Rudolph that the tree preservation lines are being preserved. Superintendent Olson reviewed the construction status of the Lexington Diffley buildings. He noted that the foundations have been poured and the expectation is that both buildings will be done by the end of August. Advisory Parks Commission Minutes of Regular Meeting of June 15,1998 Page 5 REQUEST FOR FINANCIAL ASSISTANCE - POND EXCAVATION Water Resources Coordinator Brasch brought the Commission's attention to a neighborhood, request to improve the quality of Pond JP-26.3. The residents are interested in pursuing City financial assistance to excavate the ponding area in their backyard. Since they have requested that the Commission take action on their request in July, Coordinator Brasch suggested that this issue be reviewed further by the Natural Resources sub-committee and then be brought back to the July 20 meeting. Brasch then provided an update of the Fish Lake dosing station noting that it should be ready for a start-up in mid late July. He added that both Fish Lake and Blackhawk Lake had been harvested during the past month. It was noted that the education survey results would be completed and presented to the Commission at their July meeting. STORM DAMAGE UPDATE Director Vraa noted that the maintenance staff has been working 12 hours a day, 6 days a week to try to keep up with clean-up after the storm. Superintendent Olson added that there have been 1700 calls taken from residents, 12-14 people have been working every day for the first 2 weeks following the storm but crews are getting back to their regular schedules. There are several trees leaning in and around parks and although they are unsightly, some of the trees won't be removed until later in the year, as time permits. The immediate need was to paint over oak wounds as soon as possible to mitigate the spread of oak wilt. At the present time, residents can bring their tree debris to the Yankee Doodle compost site and they will not be charged for the disposal. Otherwise they can place their tree'debris on their curb for city staff to. pick up. Superintendent Olson then shared pictures of the damage at Country Home Park and Highview Park. Member Kubik stated that he had heard many comments on the good job that city crews had done in removing tree debris and helping residents recover. Member Rudolph added his thanks to the crews as well. SUBCOMMITTEE UPDATES There were no subcommittee reports presented. POOL UPDATE Director Vraa reported that the clearing and grubbing on the site was done and the grading bids had been opened. The bids came in under projections and are currently being reviewed and the bid is scheduled to be awarded on June 16 with work beginning shortly thereafter. Advertisement for bids for the pool vessels will be completed next with the project progressing quickly thereafter. Director Vraa added that the Civic Arena expansion is about 3 weeks ahead of schedule. It appears the grand opening will be September 13.
