Respectfully submitted, Ken Vraa Date: April 17, 2000 Agenda Item: B.; Recognition of CLMP Volunteers and Sharon Holbeck u Action 4 City of Eagan Information Parks and Recreation MEMO Attachments AGENDA ITEM: B; RECOGNITION OF CLMP VOLUNTEERS AND SHARON HOLBECK TO: ADVISORY PARKS COMMISSION PREPARED BY: ERIC MACBETH, WATER RESOURCES COORDINATOR l ITEM OVERVIEW: Provide public acknowledgment of four persons who have contributed to the community by donating volunteer time and energy to help monitor and improve the water quality of lakes, ponds, and wetlands. BACKGROUND/HISTORY: Citizen Lake Monitoring Program(CLMP) Since 1989, the City has conducted a citizen lake monitoring program to help it collect water quality data on lakes and ponds. Data collected by volunteers are used not only to estimate trends in water quality, but are sent to the database of the Minnesota Pollution Control Agency, which coordinates a statewide CLMP. CLMP volunteers collect water transparency data using an 8-inch Secchi disk, a circular white metal plate attached to a length-calibrated cord. Secchi disks have been used to assess general water quality conditions since being invented over 100 years ago. Every two weeks from mid-May through September, CLMP volunteers boat to their lake and pond sampling sites, lower disks, and record the depths at which disks are no longer visible. At the end of summer, volunteers submit their data sheets to be compiled with other water-quality data. Bob Sandeen has monitored Carlson Lake for 10 years, Mark Ochs has monitored Heine and Cedar Ponds for 10 years, and Mark Brown has monitored City Pond AP-4 for 5 years. Improvement to Wetland LP-7.2 In June 1994, Sharon Holbeck wrote to Director of Parks and Recreation Ken Vraa requesting cooperation with the City in helping to restore a 3.5-acre wetland located adjacent to Lebanon Hills Regional Park. Her initiative was based on a long-term observation of the degradation of the wetland-also located near Diamond T Ranch, Inc.-, which she suspected was caused by drainage from the City stormwater system as well as runoff from the horse feedlot. The request by Holbeck led to discussions by the Natural Resources Subcommittee of the Advisory Parks Commission regarding the extent to which the City should become involved in neighborhood pond improvement projects. It further instigated field investigations of the wetland by Water Resources staff in August 1994, and in November 1996, Sharon forwarded her concerns to the City Council about potential impacts to the wetland from the horse feedlot. This action helped to advance discussions between city and state officials and ranch owners/operators and to resolve the issues regarding the conditional use permit and management plan of the feedlot. Continued communications between Water Resources staff Sharon and her neighbors led to a plan of action in 1997 to improve the water quality of LP-7.2. In exchange for public education efforts and assistance in field activities by willing and cooperative neighbors, the City treated the wetland with alum in April 1997 and conducted a series of cuttings to remove the dense population of water lily. Surveys conducted subsequent to the City's field operations indicate an improvement in the water quality of the wetland, and point to a successful cooperative venture between the City and neighborhood residents. ALTERNATIVES FOR COMMISSION CONSIDERATION: It would be appropriate for the Commission to recognize the following four dedicated individuals for their contributions to the community: • For donating volunteer time and energy, recognition plaques go to: Bob Sandeen, Mark Ochs, and Mark Brown. • For helping to improve wetland water quality, a certificate of appreciation goes to: Sharon Holbeck. DEPARTMENT HAPPENINGS APRIL, 2000 1. Adult softball begins on April 15'a with 48 teams participating in the two game tune-up at Northview Athletic Fields. The season begins on April 24U'with 218 teams registered for the 29 leagues. There are 139 men's teams, 26 women's and 53 co-rec teams.- 2. The Northview Concession stand will open for business on April 15th with a new look. The improvements include yellow walls have been replaced by a .new white wall, new roll up doors, more lighting, and some new cabinets for extra storage. 3. Information has been mailed out concerning men's and women's singles tennis, and co-rec team tennis. 4. Sand volleyball teams will register the next two weeks in April. 5. The Water Resources Division currently is coordinating the following three projects to improve water quality: ¦ Last week, to improve the stormwater treatment efficiency of a small wetland near Thomas Lake, contractors began excavating the wetland to increase its capacity to detain nutrients and sediment. This project may be completed in a week or two, but may have to be wrapped up this fall or early winter, after saturated wetland soils have refrozen. ¦ Engineering consultants are developing plans and specifications for the Fish Lake lift station, which will enable the City to lower the lake to help control curlyleaf pondweed. An open public meeting to discuss the details of the project will be held May 10, 2000 at City Hall from 7:00 p.m. to 8:00 p.m. (see attached flyer for more details). This project will be completed by mid August, and a drawdown of Fish Lake could occur as early as late Fall 2000. ¦ Planning consultants have identified a preferred option to mitigate the lead contaminated sediment of the wetland at Captain Dodd Park. In order to proceed with this option, the Minnesota Pollution Control Agency must concur with the application of an environmental seal comprised mainly of bentonite clay. The City hopes to resolve and complete this project by Fall 2000. 6. The Dakota County Environmental Education Program, the Dakota County Soil and Water Conservation District, Minnesota Extension Service, and the Water Resources Division are sponsoring a one-day workshop on Naturalizing Your Shoreline. The workshop will be held May 6, 2000, from 9:00 a.m. to 3:30 p.m. at the Eagan Fire Training Facility, 3795 Pilot Knob Road. The workshop will be limited to about 85 people who will need to pre-register for the morning and afternoon sessions. The morning session will focus on the values and functions of shoreland vegetation and about environmentally sensitive techniques. The morning session will cost $25 to cover materials. The afternoon session will be a design workshop and small-group, hands-on exercise. The afternoon session will cost $35 to cover materials. The deadline to register is April 26. See attached flyer for more details. 7. The Twin Cities Tree Trust will once again be working with staff to complete several park improvement projects this summer. The Tree Trust provides employment and training opportunities for youth and young adults. Tree trust provides transportation, supervision and insurance for the work crews. There is no cost to the City other than for the materials used in a project. Proposed projects for this summer include playground border replacements, small walls for planting areas and possibly a deck. 8. Crews from the Dakota County Sentence to Service program recently completed several projects for the City including the cutting of infield edges, trash pickup, bridge deck sweeping, clean up at Cascade Bay, and the piling of trimmed branches at the new Central Park site. The City has contracted with them for approximately 8 weeks of service this year. 9. With the assistance of the Fire Department, staff completed a controlled burn at the new Central Park site. The burn was done in an effort to reduce the accumulation of thick matted grass and weed growth that would hinder mowing and clean up. Regular mowing of select areas of the site will begin this spring. 10. Staff has begun the process of turning water back on in seasonal park buildings. The process had been delayed due to the unseasonable cold of last week. Barring any unforeseen setbacks the project will take 7-10 days. 11. The City Council has approved an agreement with Regal Cinema for the creation of a conservation easement over a wooded area originally designated for "proof of parking". In return, the City agreed to consider the area in the adjacent Rahn Park lot as an overflow area contingent upon the Cinema owners developing a connecting path if a need for additional parking was identified. Staff will monitor the process. It appears to be a good example of a "win/win" partnership. 12. The Park Maintenance and Operations Divisions report that their seasonal hiring is complete. Several seasonal positions in Forestry remain open. All report a an increase in the number of "experienced citizens" applying. 13. Staff has placed the spring order for fertilizers. Once again, high quality, slow release materials with little or no phosphorus will be used. The fertilizers to be used are determined through a process of regular soil testing. Additional testing will be done this year at a number of sites. By promoting healthy turf. 14. The Toro Company will again be using a number of park sites to test new mowing equipment. In the past, they have committed to mow designated areas for the entire season. The selected sites have typically included areas of expansive turf where minimal trim mowing is required. Staff will be meeting with Toro to discuss this years program. They continue to prefer Eagan as a test site because of the high quality of the turf. 15. Superintendent of Parks, Paul Olson, has officially been appointed to the Lebanon Hills Stake Holders Task Force. The task force has been created to provide input to the County as it updates the Lebanon Hills master plan. Additional staff may be called upon as specific elements of the plan are reviewed. Meetings are scheduled to begin in late May or early June. 16. Staff has completed the installation of new sand volleyball courts on the Dakota Hills Middle School campus. The courts are intended for school and community use. The school district has agreed to pay the cost of all materials used in the project. 17. The Forestry page of the City web site is being updated to provide additional links to web pages from around the country that provide tree related information. Callers to the City requesting general horticultural or tree information will be referred to the web site or the U or M Extension Service. Staff will continue to make disease control and mitigation a priority. 18. Park staff members Paul Olson, Paul Graham and Steve Taylor recently attended a one day Loss Prevention workshop conducted by the League of Minnesota Cities. Topics ranged from insurance waivers to bleachers. The League encourages members of its insurance trust to attend the annual workshop to ensure that members have up to date information. 19. Recreation Division staff have been conducting youth coaches training for the youth athletic association sport program coaches. We expect to train over 300 coaches. 20. Staff are working with a variety of community groups that are providing the following summer time events. Yankee Doodle Festival - June 16-17, Fourth of July, Expressfest - to be hosted this summer by the Arts and Humanities council. That event is scheduled for July 29th. Lone Oak days - at Holz Farm Sept. 15-16. 21. Once again youth athletics is popular in Eagan. Youth soccer programs are up by approx. 200 participants from last year. In house youth baseball and softball participant levels are down slightly over last year. 22. Coordination of athletic field allocations is nearly complete. Once again, our athletic facilities will be quite busy throughout the summer. 23. The summer Discover brochure will be delivered to residents the week of May 7.

Grading Plan AGENDA ITEM: G-1; SPENCER SPRINGS - STONEWOOD DEVELOPMENT CORP. TO: ADVISORY PARKS COMMISSION PREPARED BY: KEN VRAA, DIRECTOR OF PARKS AND RECREATION I ITEM OVERVIEW: Review parks, trails, tree preservation and water quality issues pertaining to a Preliminary Subdivision to divide an existing single family lot into two lots. BACKGROUND/HISTORY: Stonewood Development Corporate is requesting preliminary subdivision approval to allow the creation of a two lot single family subdivision entitles "Spencer Springs". The proposed subdivision overlays 1.3 acres of land located north of Silver Bell Road east of Nicols Road in the southwest'/4 of Section 18. In conjunction with the requested preliminary subdivision, the applicant has also requested a Comprehensive Guide Plan Amendment changing the suggested use of the property from 1ND, Limited Industrial to D-1, Single Family (0-3 units/acre.) The 1.3 acre property in question is currently unplatted and is occupied by two single family residences which were constructed in the 1940's. The existence of two single family residences upon a single lot represents a nonconforming situation as the City Code presently does not allow more than one principle building upon a lot (except via planned development). The site is presently zoned R-1, Residential Single Family and guided IND, Limited Industrial. The area in which the subject property lies was originally part of the Cedar Avenue/Highway 13 study area but was later removed. While both dwellings are accessed from the west via Nicols Road, only the northerly home is connected to municipal sewer and water. It is the intent of the applicant to remove the two existing homes on the property and construct a new single family dwelling on each proposed lot. Significant vegetation and slopes exist along the eastern edge of the property. This item is scheduled for consideration at the April 25 Advisory Planning Commission meeting. ANALYSIS: Parks and Trails Dedication This proposal would be subject to a cash parks dedication and a cash trails dedication. Tree Preservation A tree inventory has been submitted for this application. It indicates that there are both individual significant trees and significant woodlands currently existing on site. The construction of a house on the proposed lot 2 will require the removal of some of these significant trees and/or woodlands. A preliminary grading plan has also been submitted. This plan shows proposed grading on both lots I and 2. According to the City of Eagan Tree Preservation Ordinance, a Tree preservation Plan shall be submitted with the connection of new development or with any project for which a City grading permit is required. Therefore, this application shall be required to submit an Individual Lot Tree Preservation Plan with the application for a grading or building permit. Water Quality/Wetlands Due to the size and nature of this subdivision, it would be appropriate for this development to meet the City's water quality requirements via a cash dedication in lieu of ponding. There are no wetlands issues associated with this development. ALTERNATIVES FOR COMMISSION CONSIDERATION: To recommend approval subject to the following conditions: 1. This proposal would be subject to a cash parks dedication and a cash trails dedication. 2. Acknowledge that an Individual Lot Tree Preservation Plan will be required for Lot I and for Lot 2. 3. Require that tree protection measures (i.e. orange colored silt fence or four 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. 4. Require that the applicant contact the City of Eagan Forestry Division to set up a pre- construction site inspection at least five days prior to the issuance of the grading permit to ensure compliance with the approved Tree Preservation Plan and placement of tree protection fencing 5. Require that this development meet its water quality requirements through a cash dedication in lieu of ponding. (D .

AGENDA ITEM: G-2; SAFARI AT EAGAN 3'm ADDITION - FORTUNE REALTY TO: ADVISORY PARKS COMMISSION PREPARED BY: KEN VRAA, DIRECTOR OF PARKS AND RECREATION I ITEM OVERVIEW: Review parks, trails, tree preservation and water quality issues pertaining to a Preliminary Subdivision of approximately seven acres to create three lots. BACKGROUND/HISTORY: Fortune Realty is requesting preliminary subdivision approval to allow the creation of a three lot commercial subdivision entitled "Safari at Eagan". The proposed subdivision overlays 7.0 acres of land located north of cliff Road and west of Thomas Center Drive in the southwest %4 of Section 28. In conjunction with the preliminary subdivision, the application has also requested approval of a Planned Development Amendment to allow the construction of a 10,000 square foot restaurant, a 35,000 square foot, four building office development and a 146 stall parking lot (expansion for Lifetime Fitness) upon the aforementioned lots. The subject property was originally part of the Blackhawk Park Planned Development that was approved in1972. Over the years, the planned development has been revised numerous times. In 1993, the Lifetime Fitness Health Club was approved. In conjunction with the health club approval, a "second run" movie theater and a 7,500 square foot restaurant were proposed upon the subject property. In the spring of 1997, the City approved a three lot subdivision and a Final Planned Development to allow two 21,000 square foot office buildings and a 14,000 square foot movie theater upon the subject property. Because the final subdivision was not recorded within 60 days of approval however, its approval has been rendered null and void. The subject property ahs been previously graded and is void of any vegetation. A 100' Williams Brothers pipeline easement is located on the western one-half of the site. This item is scheduled for consideration at the April 25 Advisory Planning Commission meeting. ANALYSIS: Parks and Trails Dedication This proposal would be subject to a cash parks dedication and a cash trails dedication. Tree Preservation There are no tree preservation issues relative to this development proposal. 7, Water Ouality/Wetlands Stormwater runoff from this site will be directed to the east to Pond BP-13.1, which has been sized to handle the runoff from both the 2d and 3'X1 additions of the Safari at Eagan developments. Therefore, there are no additional water quality requirements for this development. There are no wetlands issues associated with this development ALTERNATIVES FOR COMMISSION CONSIDERATION: To recommend approval subject to the following conditions: 1. This proposal would be subject to a cash parks dedication and a cash trails dedication. Current Zoning and Comprehensive Guide Plan Item: Ca-Z an 3,,,t• Land Use Map 54,ed j' 9 Attachment # F.

Tree Preservation Plan AGENDA ITEM: G-3; KENNERICK ADDITION - TRI-LAND TO: ADVISORY PARKS COMMISSION PREPARED BY: KEN VRAA, DIRECTOR OF PARKS AND RECREATION S , I ITEM OVERVIEW: Review parks, trails, tree preservation and water quality issues pertaining to a Preliminary Subdivision to create 19 lots and one outlot on 8.63 acres. BACKGROUND/HISTORY: Triland Surveying Company, Inc. is requesting approval of a Preliminary Subdivision (Kennerick Addition) to create 19 lots and one outlot on 8.63 acres located northwest of Pilot Knob and Lone Oak Roads in the SE'/. of Section 4. The proposed development has a density of 2.3 units per acre. The site is moderately to heavily wooded with large variations in topography, and contains two existing single-family homes. One of the existing houses is located on the southeast corner (built in 1966) and the other in the south central part of the site (built in 1959). There is an existing pond to the west of the development site. The property is zoned R-1, Single-Family Residential. The airport noise policy contours in Eagan place the subject property within Noise Zone 4 and single-family residential development is conditional within this area. The proposed subdivision would create 19 lots, two of which will contain the existing residences (Lot 1 and Lot 16), and one outlot. The proposed outlot is located between Lots 15 and 16, and the dimensions of the outlot satisfy R- I standards for lot width, street frontage and lot area. Public street access to the development is proposed via Vincent Court, a 1000-foot long cul-de-sac to be constructed north and west from Lone Oak Road, opposite the entrance to the Timberwood Village development. A Variance is requested for the proposed cul-de-sac, which exceeds the 500-foot maximum required by the city subdivision ordinance. With the extension of city utilities into this development, the existing homes on Lots I and 16 should be connected to the City water and sanitary sewer systems. ANALYSIS: Parks and Trails Dedication This proposal would be subject to a cash parks dedication and a cash trails dedication Tree Preservation A tree inventory has been submitted for this application. It indicates that there are 111,317 square feet of significant woodlands currently existing on site. Tree species within this woodland includes primarily elm, cottonwood, oak trees. Many of the trees within the significant woodlands are in the diameter range of 6 inches to 12 inches. However there are scattered larger diameter trees with the majority of these larger trees located in the west area of this development site. As the application is currently proposed initial site grading and the preparation of twelve house pads will require the removal of 31,430 square feet of significant woodlands (28% of the total significant woodlands). According to the City of Eagan Tree Preservation Ordinance allowable removal for this type of development (Single-phase, multiple-lot residential) is set at 40%. With a proposed removal less than allowable limits there is no tree mitigation required at this initial development phase. However, five lots, lot 12, 13, 14, 15, and lot 19 are proposed to be custom graded. Tree Preservation issues for these lots will be considered at the time of Building Permit Application. The allowable removal for each lot at that time will be set at 20% of the significant vegetation on each lot. Water Quality/Wetlands This 9.6 acre development would be located in the City's H-watershed, which is in the northwest corner of Eagan but which is not associated with any high-priority water body. Nevertheless, the development needs to meet the City's water quality requirement to treat stormwater runoff from the site. The development proposes to do so by directing stormwater to an adjacent jurisdictional wetland, which would need to be excavated to accommodate the stormwater. Requirements for volume and area of water quality treatment ponds are based on the impervious proportion of proposed developments (i.e. land covered by buildings, parking lots, driveways, and walks). With an impervious fraction of 17 percent, a minimum additional (excavated) wet-pond volume of 0.47 acre-feet covering an area of 0.23 acres would be needed to treat the stormwater generated by this development. Wetlands The 0.6-acre natural wetland proposed to receive stormwater (City Pond HDP-1) is located to the southeast of the planned subdivision. Under the classification system of the Fish and Wildlife Service, this wetland is probably best considered a Type 3/4 wetland, having characteristics of both Type 3 and Type 4 wetlands, depending on seasonal hydrologic conditions. Type 3 wetlands are inland shallow fresh marshes with soils usually waterlogged early in the growing season and often covered with up to 6 inches or more of water. The vegetation of Type 3 wetlands may include grasses, bulrushes, spikerushes, and various other marsh plants such as cattails, arrowheads, pickerelweed, and smartweeds. Type 4 wetlands are inland deep fresh marshes with soils usually covered with 6 inches to 3 or more feet of water during the growing season. The vegetation of Type 4 wetlands may include cattails, reeds, bulrushes, and spikerushes. The wetland falls under the jurisdiction of both the Wetland Conservation Act of Minnesota (WCA)- administered locally by the City-and Section 404 of the federal Clean Water Act-administered by the U.S. Army Corps of Engineers. Any proposals to drain or to fill these wetlands need to meet the provisions.of these laws. This development is proposed not to drain or fill the wetland. However, as indicated above, this development would need to excavate some of the wetland to meet its water quality requirement to treat stormwater runoff from the site. The required excavation would not by itself be regulated by either WCA or Section 404, especially if the excavated material were not placed inside of the wetland boundary. If any excavated material were placed inside the wetland and whenever grading occurs within a jurisdictional wetland, state and federal wetlands regulations do apply because those activities are considered to be filling. However, the developer of this site can apply to the City for a certification of no-loss determination, because no net loss of wetland is proposed. With this application, the developer is required to submit a wetland delineation report and a detailed plan for the excavation and grading of the wetland. Upon acceptance and approval of the application by the City, work could begin after a statutory 15-day public appeal window had lapsed, or in the event of an appeal, until the appeal had been finalized. Work to create stormwater treatment in the wetland also would need to be coordinated with the City's Engineering Division, which is responsible for implementing the Stormwater Management Plan. /0. Erosion Control In several areas of this development, particularly to the west of the proposed cul-de-sac, the topography of the site requires proper installation and effective maintenance of erosion control practices to prevent and minimize soil loss and impacts to down-gradient resources and water quality. ALTERNATIVES FOR COMMISSION CONSIDERATION: To recommend approval subject to the following conditions: 1. This proposal would be subject to a cash parks dedication and a cash trails dedication. 2. To acknowledge that there is no tree mitigation required for initial site development. 3. To acknowledge that an Individual Lot Tree Preservation Plan will be required for Lots 12, 13, 14, 15, and 19 at the time of Building Permit Application. 4. To require that tree protection measures (i.e. orange colored silt fence or four 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. This tree protection fence shall be installed prior to any grading or tree removal. 5. To require-that the applicant contact the City of Eagan Forestry Division to set up a pre- construction site inspection at least five days prior to the issuance of the grading permit to ensure compliance with the approved Tree Preservation Plan and placement of tree protection fencing. 6. To require that the applicant meet the City's water quality requirements by excavating from the nearby wetland a minimum additional wet-pond volume of 0.47 acre-feet covering an area of 0.23 acres. The stormwater treatment pond should be constructed according to NURP standards with a maximum depth of 6 feet, a 10:1 aquatic bench, and an outlet skimmer according to City design standards. 7. To require a minimum 30-foot wide buffer of natural, undisturbed vegetation outside the boundary of the wetland should be maintained before, during, and after construction. 8. To require that erosion control practices be property installed and effectively maintained (particularly to the west of the proposed cul-de-sac, where the topography is steep), throughout the development process to prevent and minimize soil loss and negative impacts to down-gradient resources and water quality.

TO: ADVISORY PARKS COMMISSION PREPARED BY: KEN VRAA, DIRECTOR OF PARKS AND RECREATION I ITEM OVERVIEW: Review parks, trails, tree preservation and water quality issues pertaining to a Comprehensive Guide Plan Amendment, PD Amendment and Final Planned Development for a Sam's Club. BACKGROUND/HISTORY: Wal-Mart Stores, Inc. is requesting approval of a Comprehensive Guide Plan Amendment from Limited Industrial to Commercial Planned Development, and an Amendment to the Planned Development to allow a retail use on Lot 3, Block 1, Eagandale Center Industrial Park No. 9. The site consists of approximately 15 acres and is located on Denmark Avenue opposite Clubview Drive, east of I-35E and south of Lone Oak Road, in the NEt/4 of Section 10. This site has been designated in the City's Comprehensive Guide Plan for industrial land use for over 20 years, and in the City's Draft Comprehensive Guide Plan (1999), it is designated for Business Park use. In 1987, a Preliminary Planned Development was approved for Eagandale Center Industrial Park No. 9 (south of Lone Oak Road between I-35E and Lexington Avenue), and this site was approved for development of a health/fitness club or office/industrial use. The proposed 130,000 square foot Sam's Club, because of the retail nature, is not consistent with the land use designation and Planned Development for this property. Therefore, the applicant is requesting amendments to both the City's Comprehensive Guide Plan and the existing Planned Development. The site is open and relatively flat and abuts I-35E to the west. Surrounding properties include an extended stay hotel to the north (Homestead Village), office/showroom to the east, and U.S. Postal Service bulk mail center to the south and southeast. The building is proposed to be located in the southern portion of the site with parking to the north and a stormwater pond in the northeast corner. The primary street access for the proposed development is via Denmark Avenue opposite Clubview Drive, with a secondary access from Denmark Avenue at the southeast corner of the site. The plans include an extension of the existing sidewalk along the west side of Denmark Avenue. ANALYSIS: Parks and Trails Dedication This proposal would be subject to a cash parks dedication and a cash trails dedication. Tree Preservation There are no tree preservation issues with this development. Water Quality/Wetlands This proposed development would be located in the City's D-watershed, which is associated with LeMay Lake (DP-2), one of the City's highest priority (Class I-Direct Contact) water bodies. Because of the size of this development and the extent of its impervious cover, a stormwater treatment pond will need to be constructed on-site. The design of the water quality treatment pond should be according to NURP standards with a minimum, wet-pond volume of 2.38 acre-feet and a surface area of 0.59 acres. The pond should have a maximum depth of 10 feet, a 10:1 aquatic bench, and an outlet skimmer according to City design standards. The developer is proposing to construct an infiltration basin to treat stormwater, based on the existence of sandy soils at the site. Were the permeability of those soils to diminish over time from the addition of silt in the stormwater, the volume of the pond proposed by the development would be adequate to treat stormwater by wet-pond detention. There are no wetlands issues associated with this development. ALTERNATIVES FOR COMMISSION CONSIDERATION: To recommend approval subject to the following conditions: I. This proposal would be subject to a cash parks dedication and a cash trails dedication. 2. To acknowledge that this proposal would not be subject to tree preservation mitigation. 3. To require that a stormwater treatment pond be constructed according to NURP standards with a minimum, wet-pond volume of 2.38 acre-feet and a surface area of 0.59 acres. The pond should have a maximum depth of 10 feet, a 10:1 aquatic bench, and an outlet skimmer according to City design standards.

Alternative Review and Analysis AGENDA ITEM: I-1; CAPTAIN DODD PARK SEDIMENT MITIGATION TO: ADVISORY PARKS COMMISSION PREPARED BY: ERIC MACBETH, WATER RESOURCES COORDINATOR I ITEM OVERVIEW: Recommend the City Council to direct the preparation of plans and specifications for sediment mitigation Option A (bentonite clay cover), contingent upon approval of Option A by the Minnesota Pollution Control Agency. BACKGROUND/HISTORY: Lead contamination of upland soils and wetland sediment at Captain Dodd Park was identified in 1997. Due to the nature of this contamination, the Minnesota Pollution Control Agency (MPCA), the state regulatory agency for such issues, previously determined the need to mitigate the site. A series of investigations and plans led to the implementation in 1998 of Phase I of the mitigation, which successfully resolved the issues of the upland portion of the site. Phase H, mitigation of the sediment contamination in the park's wetland, remains to be implemented. Refer to Attachment A for more background details. ANALYSIS: A review by Barr Engineering of alternatives for sediment mitigation identified two basic options: 1) to excavate the contaminated sediment, or 2) to seal effectively the sediment in place. A recent analysis of these two options by the consultant essentially represents a recommendation to pursue Option A, which is to cover the sediment with a bentonite clay compound. Refer to Attachment B for more details on the review of alternatives. DISCUSSION/EVALUATION: Although the City is under no regulatory pressure or timeline at this point, the fact is that the contamination of Captain Dodd Park is not fully resolved environmentally and administratively. Because the Advisory Parks Commission is charged with overseeing parks and natural resources issues, it now appears to be the appropriate time for the Commission to recommend actions that lead to effective closure of this matter. Of the two options analyzed by Barr Engineering, Option A clearly is in the City's best interests financially. According to the review by the consultant, this option also appears to be environmentally acceptable. Option B, while so far appearing to be the slight preference of the MPCA, would not only be more expensive, but could be problematic in terms of implementation and short-term risks. Despite the MPCA's apparent apprehension in a meeting a month ago, the agency's representatives were amenable to reviewing the merits of a "sediment cap" option. Refer to Attachment C for more details on the analysis of alternatives. Regardless of the option, the implementation of Phase II will be funded through the Storm Water/Water Quality Capital Improvements Plan. /5 ALTERNATIVES FOR COMMISSION CONSIDERATION: It would be appropriate for the Commission to recommend the City Council to direct the preparation of plans and specifications for sediment mitigation Option A (bentonite clay cover), contingent upon approval of this option by the Minnesota Pollution Control Agency. 40 :V)4'~IGd~7( 54i Item: 1-1 Cpp~Mn Lid I . Attachment # 2.0 Background 2.1 Site History and Description A Phase I Report and Phase U Work Plan was prepared in September 1997. The results of this report are summarized below. The Property is approximately 15 acres in size and is located in the east one-half of Section 24, Township 27 North, Range 23 West (Figure 1). Vehicular access to the Property is available via Country View Drive. The Property is located in a semi-rural area containing mixed residential, commercial and retail properties. Because the Property is a neighborhood park, most of the Property is surrounded by residences. It is bordered on the north, northeast, west and southwest by private homes. The residences to the west and southwest are separated from the park by Country View Drive. The Property is bordered on the southeast and east by the former Kisling Property. The Property is approximately level in its central portion and increases sharply in elevation along its eastern border, as shown in Figures 1 and 2. The southeastern and eastern portions of the Property steeply ascends into the former Kisling Property. The surface elevation ranges from approximately 845 feet in the central portion of the Property to 884 feet above mean sea level on the northeastern portion of the Property. Surface soils are composed of fine-to-medium grained sands, silty sands, and silts with some clay and gravel. Depth to groundwater is 45 to 60 feet below ground surface (BGS) based on data from monitoring wells installed on the Property by Braun in 1989. Groundwater flow is assumed to be to the east southeast towards the Mississippi River. A pond is located on the central portion of the Property. The pond is designated by the City of Eagan (City) as JP 24 and is classified in the city system as a "nutrient trap" intended for stormwater retention. The pond, which may be seasonally dry, has a maximum depth of approximately 4 to 5 feet and an estimated sedimentation rate of 3 to 15 millimeters per year (mm/yr) (Brasch, 1998). No wells are located on the Property. A well search was conducted in the vicinity of the Property to identify wells known or suspected to exist within a one mile radius. This well search is discussed in more detail in Appendix B of the 2319437158040-]/DSD 2 Phase I Report. The majority of the wells in the area are finished in either bedrock or gravel deposits at depths between 133 and 380 feet BGS. 2.2 Previous Environmental Investigations Braun conducted an investigation of the restaurant debris area on the south end of the pond that included the installation of soil borings and monitoring wells. This investigation is discussed in detail in the Phase I and Phase II Work Plan (1997). As discussed in this report, the City plans to remove debris observed along the shoreline of the pond. During the investigation of the former Kisling Property, one soil sample was collected on November 26, 1996 in the drainage path from the former Kisling Property next to the pond at Captain Dodd Park. The sample was collected at a depth of 0 to 0.5 feet and had a lead concentration of 820 milligrams per kilogram (mg(kg). The sample location is shown on Figure 2. On June 3, 1997, nine surficial soil samples were collected along the asphalt walking/biking path and analyzed for lead. The'results are shown on Figure.2 and included in Appendix A. Lead concentrations in a number of the surface soil samples at the Property exceeded the Ecological Soil Screening Criteria of 50 mg/kg but were below the MPCA's April 1996 Draft Site Screening Evaluation Guidelines for Soil Screening Criteria of 400 mg/kg of lead for residential settings. Previous MPCA approved response actions in areas of ecological risk have used 100 mg/kg as a response action goal. Concentrations of lead from the June 1997 investigation range from background concentrations to a maximum concentration of 450 mg/kg at a depth of 0-3 inches (Sample 9). 2.3 Scope of Work The Phase II Investigation focused on soil sampling in areas of potential lead contamination not sampled during previous investigations. The Phase II Investigation did not include a groundwater quality investigation, as the planned future use of the Property will not include the use of the groundwater. The objective of the Phase II Investigati on was to characterize soil and sediment so that lead contaminated soil could be identified and the appropriate remedial action could be implemented. The work performed on November 6 and 7, 1997 during the Phase II Investigation was consistent with the program described in the Phase II Work Plan with the following exceptions: I 2319437 \58040-1/DSD 3 • Eight soil samples were collected at the surface (0 to 3 inches) and at depth (12 inches) instead of the originally proposed total of six surface (0 to 6 inches) soil samples. The above soil samples were analyzed for total lead. • Three sediment samples in the pond next to the drainage point from the former Kisling Property were collected instead of two samples. The additional sample was collected at depth (12 inches). The above sediment samples were analyzed for total lead. • An additional sediment sample was collected near the restaurant debris area and analyzed for lead, volatile organic compounds (VOCs) and semi-volatile organic compounds (SVOCs). After reviewing the analytical results of the sediment samples, an additional investigation was conducted on January 22, 1998 to characterize potential contamination in the pond. Six sediment samples were collected at the surface of the pond sediment (0 to 3 inches) and three samples were collected at a depth of one foot. Two of the shallow samples were analyzed for arsenic, antimony and mercury as recommended by the Minnesota Department of Health (MDH). 2319437 \58040-]/DSD 4 I 3.0 Phase 11 Site Characterization Methods and Results The Phase II Investigation activities included the collection of soil samples at the surface and at depth and the collection of sediment samples from the pond sediment surface and at depth. Figure 2 shows the Phase II sampling locations and Table 1 presents the sampling locations, analytical results and sampling depths. The following sections describe the Phase II Investigation methods and results. The discussion of results summarizes data from this investigation at the Property. 3.1 Investigation Methods The field investigation consisting of sediment and soil sample collection was performed on November 6 and November 7, 1997. The additional sediment sample collection was performed on January 22, 1998. Surface soil samples (identified as SL-1A through SL-8A) were collected- at a depth of 0 to 3 inches BGS with a stainless steel trowel. Each sample was screened for visible contamination (e.g., discoloration, oiliness, odors). Grab surface samples were submitted for analysis of total lead concentration, no composite samples were collected. Soil samples were collected at a depth of one foot from the same locations as the surface soil samples (samples were identified as SL-1B through SL-8B). Each soil sample was described and screened for visible contamination (e.g., discoloration, oiliness, odors). Soil samples were submitted for analysis of total lead concentration, no composite samples were collected. Sediment samples were collected from the pond bottom surface (Samples S-1 through S-3) and at a depth of one foot at location S-3 (sample S-3B). Sample locations were accessed by a canoe, and samples were collected with a petite ponar dredge (samples S-1 through S-3) and a soil recovery probe (sample S-3B). All samples were analyzed for total lead. Sample S-1, located near the restaurant debris area, was also analyzed for semi-volatile organic compounds (SVOCs) and volatile organic compounds (VOCs). 2319437 \58040-1/DSD 5 I Additional sediment samples were collected from six locations across the eastern half of the frozen pond in late January. Samples and sampling locations from this event are identified as SD-1 through SD-6 as shown on Figure 2. Samples were collected at the sediment surface only (0-3 inches BGS) at three sample locations (SD-1, SD-2 and SD-4) and both at surface and at depth (12 inches BGS) at the remaining sample locations (SD-3, SD-5 and SD-6). After sample locations were identified by a Barr Geologist, a City employee hand drilled through the frozen pond surface (approximately one foot thick) with an ice auger. Sediment samples were then collected from the pond bottom using a soil recovery probe with a five foot extension rod. The soil recovery probe has a one foot long cylindrical tube open at the bottom which allows samples to simultaneously be collected from both the surface of the pond bottom and at a sediment depth of one foot. Sample collection began at the western-most sample location, where the sediment was presumed to be cleanest, and proceeded eastward. Grab samples were submitted to Legend Technical Services laboratories (Legend) located in St. Paul for analysis. All samples were analyzed for total lead concentration. Samples 3A and 6A were further analyzed for mercury, arsenic and antimony. All field sampling, screening, decontamination methods, and quality assurance procedures were conducted in accordance with Barr Standard Operating Procedures shown in Appendix G of the September 1997 Phase I Environmental Assessment Report and Focused Phase II Investigation Work Plan. Observations were recorded on test soil sample data sheets; field screening results, logs, and data sheets are in the field sampling reports in Appendix B. Table 1 summarizes sample activities, general observations, samples and parameters analyzed. Analytical results are summarized in Table 1 and presented in Appendix A. 3.2 Investigation Results To evaluate whether chemical concentrations indicate the need for remediation, measured concentrations were compared to the following soil screening concentrations: lead concentrations were compared to the draft MPCA's Site Screening Evaluation Guidelines for Soil Screening Criteria of 400 mg/kg and the proposed Ecological Soil Screening Criteria of 50 mg/kg. However, recently approved response actions in areas of potential ecological areas have used a response action of 100 mg/kg for lead. The ecological risk values for antimony is 5 mg/kg, arsenic 10 mg/kg and mercury 0.1 mg/kg. Laboratory results are shown in Table 1. 2319437 \58040-1/DSD 6 j Kisling Drainage Area A total of twelve sediment samples were collected in the pond in order to delineate the extent of drainage from the former Kisling Property into the lake. Samples were collected as far east as the pond/land boundary and as far west as approximately one-hundred feet east of the cattails located in the central portion of the lake. Sediment samples were collected both at the surface and at depth and were analyzed for total lead concentrations. Two samples, Samples SD-3A and SD-6A were also analyzed for arsenic, mercury and antimony. Soil sampleswere collected along the eastern portion of the Property where drainage occurs from the former Kisling Property. Soil samples were collected in eight locations at both the surface (0 to 3 inches BGS) and at depth (12 inches BGS). Samples were analyzed for lead concentrations only. A response action goal of 100 mg/kg was used to delineate the area of lead contaminated soil and sediment (see Figure 2). Sediment samples S-2, S-3A, S-3B, SD-6A and SD-6B had lead concentrations exceeding the cleanup criteria with concentrations ranging from 230 mg/kg to 640 mg/kg. Sediment samples collected and analyzed for antimony, arsenic and mercury did not exceed the response action ecological risk values discussed previously. Results from the lab analysis was used to delineate the area for response action implementation as shown on Figure 2. Soil samples SL-2A, SL-3B, SL-4A, SL-6A, SL-8A and SL-8B had lead concentrations exceeding the cleanup criterion with concentrations ranging from 100 mg(kg to 1,100 mg/kg. Samples at depth (the B series) generally did not exceed the cleanup criterion. Results from the lab analysis was used to delineate the area for response action implementation, as shown on Figure 2.

Alternative 1 is a bentonite cover over contaminated sediments and Alternative 2 is ri'moval of sediments and disposal in an off-site landfill. These alternatives are screened on threshold and balancing criteria in Table 2. The response actions for lead contaminated sediment is the only response action component evaluated. The technology descriptions are detailed within the discussion of the alternatives. The costs of the various alternatives are shown in Table 3. Table 3 includes the costs for both moderate and high volume assumptions for Alternatives 2; high volume assumptions assume an additional 0.5 feet must be excavated. Alternative I does not require a high volume cost estimate. 3.1.1 Alternative 1: Bentonite Cover Over Sediment Figure 2 shows the response action implementation area for this alternative. The response actions for Alternative 1 includes the following major components: • Lead contaminated sediment with concentrations greater than 100 mg/kg will be covered with a 5- to 6-inch bentonite cover. The proposed soil cover material for the project is AquablokTM composite particles, a proprietary blend of clay minerals, polymers, and an aggregate core. An equivalent product could be used also. • The bentonite will be placed into the pond with a truck mounted telescopic conveyor (no dewatering is necessary). • The natural sedimentation of the pond will continue at a rate of 3 to 15 mm/yr, blanketing the bentonite cover and the lead contaminated sediment. Based on research discussed below, natural flora and fauna are anticipated to be reestablished within one to two seasons without replacement of sediment. • Place institutional controls on the pond along with the soil cover area. Aquablok7" Cover AquablokTM composite particles consists of a clay mineral based (often bentonite-rich) outer shell that is fixed with polymers to a nucleus comprised of gravel or other hard material such as glass ::ODMA\PCDOCS\DOCS\214833\1 5 Gullets (AquablokTM, 1999). Upon wetting, the particles hydrate and physically expand around the dense nucleus. The heavy nucleus allows the particle to sink to the bottom of the water column and grows to form an erosion-resistant layer of very low permeability. AquablokTM acts as a physical, hydraulic, and chemical barrier between contaminated sediments and the overlying water column, protecting flora and fauna and also minimizing contaminant movement in the food chain (Aquablok TM, 1999). Fact sheets on Aquablok TM are included in Appendix A. The AquablokTM particles are hard, smooth marble-like particles that flow easy from a conveyor or bucket and sink quickly to the bottom forming a continuous layer. Aquablok TM has been used in a variety of hydrologic environments including flowing rivers, estuaries, deep lakes, and wetlands. Aquablok TM is resistant to harsh weather conditions including erosion, seasonal flooding, and freeze/thaw stresses. The field scale vertical and hydraulic permeability range from 10-8 to 10-9 cm/sec. (AquablokTM, 1999). The primary functions of the Aquablok TM cover include the following: • Reduce the flux of dissolved sediment borne contaminants into the overlying water column, • Physically stabilize contaminated sediments, preventing their re-suspension and transport to other sites, and • Physical isolation of contaminated sediments from the benthic (macroinvertebrate) environment. The natural deposition of clean sediments over the AquablokTM cover over time would also isolate organisms from contaminated sediments to an even greater degree (Aquablok TM, 1999). Published research indicates that naturally occurring montmorillonite and bentonite can not only sorb innocuous base-metal cations like calcium, magnesium, and sodium, but can also sorb-or attenuate-potentially toxic heavy metal cations onto clay surfaces, effectively keeping such metals out of the bulk solution phase of pore and surface waters (Aquablok TM, 1999). AquablokTM has been proven effective in reducing organism exposure to contaminated sediments and offering a viable substrate for re-establishment of indigenous flora and fauna (Hull, 2000). The material is physically similar to fine-grained sediments and provides a comparable replacement substrate for indigenous flora and fauna thus minimizing impacts to wetland organisms (Hull et al., 1999a). In addition, a small increase in substrate elevation (existing sediment elevation with 4- to 6-inch cover) would likely have an insignificant effect on spatial distributions of wetland plant ::ODMA\PCDOCSiDOCS\2 [483311 6 communities, as opposed to potentially significant ecological effects associated with much thicker (e.g. foot-plus) sand-based remedial sediment caps (Hull et al., 1999b). Also, results of a pilot-scale capping study conducted on white-phosphorous impacted sediments occurring in an estuarine salt marsh ecosystem in Alaska indicated a lush re-growth of emergent wetland vegetation within about one year of Aquablok TM application (Hull et al., 1998). In terms of invertebrate recolonization of Aquablok TM, small red worms were also reportedly observed to occur within capping material at the Alaskan wetland capping site during the following growing season (Hull et al., 1999b). Benthic invertebrate organisms typically colonize only the upper few inches of sediment, and should remain isolated from contaminated sediments (Hull and Stephens, 2000). The Aquablok TM particle system was originally developed in 1994 at the Fort Richardson Superfund site in Alaska to address waterfowl mortality from contact with white phosphorus contaminated wetland sediments (Hull and Stephens, 2000). An Aquablok TM cap ranging in depth from 5 to 10 centimeters (cm.) was used to cover the sediments. Following the application of the barrier to one of two contaminated ponds, greater duck foraging and higher mortality was observed in the untreated pond and no mortality in the treated pond after a year of tidal inundations and ice effects. Emergent vegetation recovered within a year of treatment. White phosphorous levels in the barrier were less than the method limit of detection, indicating no migration of white phosphorous into the material. Barrier thickness remained relatively stable over a period of 4 years, and vegetation was found to be important in stabilizing the barrier material (Pochop et al., 2000). Construction of the AquablokTM Cover The Aquablok TM cover for the pond at Captain Dodd Park could be constructed using a truck- mounted telescopic conveyor, a front end loader, and a hopper. A Putzmeister Telebelt TB 105 could be used on the pond and has been demonstrated for application of Aquablok TM on similar sites. Appendix B includes a description of the equipment. The equipment would be able to reach into the pond 105 feet from the shoreline. The contamination is estimated to extend approximately 90 feet into the pond as shown on Figure 2. Placement of the cover could be completed in one day with two equipment operators and one laborer. The conveyor would most likely be placed in the area of the soil cover because that area is the most accessible. The equipment may cause minor impact to the soil cover which would be repaired if disturbed. The Aquablok TM cover would be applied at a rate of 8.5 pounds per square foot (lbs/ft2). Approximately 5,000 square feet (ft=' would be covered. Core samples would be collected in approximately 5 to 10 locations to check coverage and depth of material. ::ODMA\PCDOCS\DOCS\214833\1 7 FFAs presented in research above, an additional sediment layer from a clean area of the pond is not necessary. It would require significant disturbance in another area of the pond to excavate the sediment. Then, to place the sediment onto the cover would require dewatering the pond, placing the sediment, and refilling the pond. If in two years from application of the cover, no vegetation is observed, sediment from another area of the pond could be excavated and placed on the cover as a contingency. 3.1.2 Alternative 2: Remove and Dewater Sediments and Dispose in a RCRA Subtitle D Facility Figure 2 shows the response action implementation area for this alternative. The response action for Alternative 2 includes the following major components: • Lead contaminated sediment with concentrations greater than 100 mg/kg will be removed from the pond. There are two primary methods that the sediments could be removed. The first method is to dewater the portion of the pond that is contaminated and allow the sediments to drain as much as possible (possibly over one to two weeks, the longer the better). A sediment stabilization and mixing area would need to be constructed to place the sediments to mix with a stabilization material such as sawdust. Excavation could be accomplished with special equipment including swamp mats or a platform constructed into the pond to place the equipment on. The sediment mixing area would be most likely in the soil cover area next to the pond. The sediment mixing area and trucks hauling sediment would most likely impact the integrity of the soil cap that was constructed in 1998. The sediment excavation and mixing and disposal would take approximately one week to complete. Another option for removing the sediments that would have less impact on the existing soil cover is to dredge the sediments to large tanks and remove the water through sedimentation and sand filter beds. The tanks could be located in the park parking lot. Drying beds would need to be constructed at most likely an offsite location, possible at the City's public works area. (Eric -just some ideas we will want to talk through.) The approximate in-place volume of the.sediment to be removed is 300 cubic yards. This assumes approximately 5,000 ft2 and a depth of 1.5 feet. • The sediment after mixing with sawdust or other material will be transported to a RCRA Subtitle D facility. Waste profile samples for the disposal facility will need to be completed prior to disposal. • Verification samples would be collected in the excavated area of the pond. ::ODMA\PCDOCS\DOCS\214833\1 8 • The soil cover may require significant repair in the area of the mixing bed and truck hauling area. The work could be completed in the late fall to minimize impact to the park and soil cover area. • Portions of wetlands along the shoreline will need to be restored. • A portion of the Park may require closing during these activities. 3.2 Clean Water.Act Section 404 Permit Both alternatives would require an U.S. Army Corps of Engineers (ACOE) Clean Water Act Section 404 permit. Effective January 31, 2000, all Department of the Army Section 404 Nationwide Permits in Minhesota except within the exterior boundaries of Indian Reservations were suspended and are replaced by Proposal GP/LOP-98-MN. GP/LOP-98-MN provides a general permit (GP) authorization for certain minor activities that are authorized without any requirement to apply to or contact the Corps, provided that the activities are conducted in compliance with all GP/LOP-98-M conditions. GP/LOP-98-MN also provides abbreviated, Section 404 letter-of-permission (LOP) evaluation procedures for almost all other activities that would impact less than two acres of water/wetland area (COE, 2000). The public notice, matrix summary and Local-State-Federal Water Resource Combined Project Application (CPA) Form for General Purpose Projects are included in Appendix C. The CPA form would be completed and submitted to the ACOE and the Wetland Conservation Act Local Government Unit (WCA LGU). The WCA LGU for the pond is the City of Eagan. The pond is not within the jurisdiction of the Department of Natural Resource (DNR), Division 6 and therefore no permits are required. A fax letter stating, this is included in Appendix C. After the CPA is submitted, the LGU and ACOE must notify and advise the City of additional permit requirements within 45 days. At that time, the ACOE will decide with the work would be included under a GP or an LOP. It is anticipated that an LOP B, as shown in the matrix summary would be required for the project. Wetlands would not be eliminated in either alternative. The permit process would be completed as part of the response action design. ::ODMAIPCDOCS\DOCS\214833\1 9 4.0 Revised VRAP The following sections discuss the proposed response action for the contaminated pond sediment located at the Property. 4.1 General Approach Based on the results of the Phase II Investigation and previous investigations, the Property shows concentrations of contaminants in excess of the recommended response action goals for lead. The recommended response action is Alternative 1, bentonite cover over the lead contaminated sediment. The proposed response actions will result in a 'remedy that is protective to human health and the environment. The propose response actions include discussions of the following: • Proposed cleanup goals • Proposed remedial technologies and a brief discussion of the considerations that supported the selection of those technologies. • Conceptual design for the proposed response actions. • Implementation schedule. 4.2 Chemicals of Concern and Cleanup Levels The chemical of concern for the Property is lead. The proposed cleanup level of 100 mg/kg for the Property is below the draft MPCA's Adult Human Health-Based lead Cleanup Goal for Residential Settings. In addition, because the sediment will be covered, the proposed cleanup level will also meet the MDH "bare .soil lead abatement standard" of 100 mg/kg established in Minnesota Rules Ch 4761. The proposed cleanup level is based on and is consistent with response actions recently approved and completed at other similar VIC program projects. ::ODMA\PCDOCS\DOCS\214833\1 10 4.3 Response Action Conceptual Design The proposed sediment response actions are expected to be implemented in the Summer of 2000. The specific tasks would be completed in the following order: • Acquire permits • Delineate response action area with floats in the pond • Place Aquablok' "1 cover • Verify cover and thickness • Implement institutional controls • Repair soil cover area as necessary The proposed area of the cover for the lead contaminated sediment in the pond can be completed using construction equipment discussed in Section 3.0. 4.4 Overall Protection of Human Health and the Environment The completed proposed response actions will provide overall protection for human health and the environment. 4.5 Long-term Effectiveness and Potential Reduction of Contaminant Mobility Because the lead and other metals present at the Property are elements, permanent remedies are not available that would result in the destruction of the metals present in the soil. Placing a cover over the sediment will not reduce the toxicity or volume of the lead, but will provide long-term reduction in potential exposures and mobility. Implementation of institutional controls will be necessary for the future operation, maintenance and monitoring of the Property. Institutional controls include, but are not limited to, deed notification or restriction on the Property and annual inspection by the City of the soil cover area and sediment cover. ::ODMA\PCDOCS\DOCS\214833\1 11 4.6 Implementability The components of the response actions include placement of the bentonite cover with a conveyor over contaminated sediments. These components have been demonstrated at other sites and are commercially available. 4.7 Short-Term Risks Possible short-term risks include Property security. Property security would need to be established during on-site response actions to minimize risks of the public coming into direct contact with equipment. Property security will be provided by completing a temporary fence around the area of response action implementation. Because sediment excavation is not proposed, issues of surface water run off and dust control are not concerns. A health and safety (H&S) plan would not be required because no excavation of contaminated materials will be completed. Standard health and safety procedures for construction work will be followed. 4.8 Summary and Schedule The following tasks will need to be completed: • Submit and obtain MPCA approval of the Focussed Feasibility Study and Revised VRAP • Obtain necessary permits • Develop final design plans and associated cost estimate for the work • Solicit contractor bids and contract for the work • Conduct sediment response actions • Receive a No Action letter and No Association Determination from the MPCA, VIC program • Implement institutional controls ::ODMA\PCDOCS\DOCS\21483311 12 The anticipated schedule for completing the response action is approximately two to three months for the permit, one day for delineation, one day for placement of a bentonite cover over the lead impacted sediment. ::ODMA\PCDOCS\DOCS\214833\1 13 Table 2 Screening of Alternatives for Sediment Captain Dodd Park Screening Alternative 1: Alternative 2: Dewater Pond and Excavate and Comment Criterion Place Bentonite and Sediment Cover over Sediment Dispose Contaminated Sediment Overall Protection of MEDIUM-HIGH MEDIUM-HIGH • • Both alternatives are protective Human Health, • Protective of human health and the environment. • Protective of human health and the environment. of human health and the Welfare and the • Bentonite cover over the lead contaminated sediment will • Ecological receptors may be put at risk by disturbing environment.

CITY OF EAGAN CITY COUNCIL By: Its Mayor Attest: Its Clerk Motion made by: Seconded by: Those in favor: Those against: Dated: CERTIFICATION I, E. J. VanOverbeke, Clerk of the City of Eagan, Dakota County, Minnesota, do hereby certify that the foregoing resolution was duly passed and adopted by the City Council of the City of Eagan, Dakota County, Minnesota, in a regular meeting thereof assembled this 18th day of April, 2000. E. J. VanOverbeke, City Clerk Date: April 17, 2000 Agenda Item: J-2.; 5-year Review of Water Quality Management Plan Action X City of Eagan Information Parks and Recreation MEMO Attachments X Copy of the 1990 Water Quality Management Plan (provided at the meeting) AGENDA ITEM: J.2; 5-YEAR REVIEW OF WATER QUALITY MANAGEMENT PLAN TO: ADVISORY PARKS COMMISSION PREPARED BY: ERIC MACBETH, WATER RESOURCES COORDINATOR ITEM OVERVIEW: Initiate a second 5-year review of the Water Quality Management Plan. BACKGROUND/HISTORY: With the adoption of the City of Eagan Water Quality Management Plan (WQMP) in April 1990, the City Council included a provision to carry out a review of the program every five years. To fulfill that requirement, the Advisory Parks Commission, through its Natural Resources Subcommittee, conducted the first review in 1995. That review, summarized to the City Council in November 1995, included an overview of the revenues and expenditures for that portion of the program funded through the storm water utility fund, a summary of data on water quality for key high priority water bodies identified in the plan, and a summary of recommendations for changes in program policies and priorities in several different areas. Two directives were issued to Advisory Parks Commission by the City Council in 1995 after the first review. The first was to postpone indefinitely the draft residential lawn chemical ordinance. The second was to proceed with drafting a wetland buffer ordinance. ANALYSIS: The City is in a much better position now, 5 years after the initial 5 years of the WQMP, to conduct an overall review of program elements and water quality data in order to propose adjustments in policies and priorities to meet present and future conditions. DISCUSSION/EVALUATION: This agenda item represents the initialization of a process that staff estimates will take 4 to 6 months. The first meeting of the subcommittee could occur as soon as May or June. However, at least two issues--subcommittee discussions on wetland protection policies and the implementation of the street sweeping study-may extend the minimal 4-month timeline of the review. In any case, staff hopes to complete the review of the program no later than December 2000. Staff recommends the following generalized plan for the review of the WQMP: May or June Review of program elements and water quality data to answer, "What has happened over 10 years?" June or July Review of present situation to answer, "Where is the program nowT' /q. July or August Projection of future directions to answer, "Where is the program going?" August or September Recommendations for adjustments in program policies and priorities to meet present and future conditions to answer, "What changes need to be made?' ALTERNATIVES FOR COMMISSION CONSIDERATION: It would be appropriate for the commission to direct its Natural Resources Subcommittee to initiate the second 5-year review of the Water Quality Management Plan.

Mark Filipi, Floyd Hiar, Barbara Johnson, Daryle Petersen, Dorothy Peterson and John Rudolph. Members not present included Kevin Gutknecht and George Kubik. Staff present included Ken Vraa, Director of Parks and Recreation; Paul Olson, Superintendent of Parks; Gregg Hove, Forestry Supervisor; Pam Dudziak, Project Planer and Cherryl Mesko, Recording Secretary. AGENDA Barbara Johnson moved, Joseph Bari seconded with all members voting in favor to accept the agenda as presented. MINUTES OF REGULAR MEETINGS OF JANUARY 10 AND FEBRUARY 14, 2000 Relative to the January 10 minutes, Member Peterson asked for clarification relative to the Murphy Farm 3rd Addition land acquisition action that was taken. She understood that Member Kubik stated that the purchase of a portion of this development was not intended to set a precedent for future development proposals. Since Member Kubik was not in attendance to clarify his comments, the minutes from the January 10 meeting were deferred to a time when the question could be clarified. Terry Davis moved, Dorothy Peterson seconded a motion to accept the minutes of the regular meeting of February 14 as presented. All members voted in favor with the exception of Member Petersen who abstained from voting, noting that he was not in attendance at that meeting. VISITORS TO BE HEARD There were no visitors wishing to address the Commission under this agenda item. DEPARTMENT HAPPENINGS Items highlighted by Director Vraa included CONSENT AGENDA Member Petersen asked that the Slumberland Addition proposal be pulled from the Consent Agenda for further discussion. Daryle Petersen moved, Barbara Johnson seconded with all members voting in favor to recommend approval to the City Council of the following proposals subject to the following conditions:. 1. Pfeifer Addition - Gene and Brenda Pfeifer. 1 This proposal would be subject to a cash parks dedication and a cash trails dedication. Acknowledge that an individual lot tree preservation plan will be required for Lot 2, Block 1 at the time of building permit application. Require that Tree Protective measures (i.e. orange colored silt fence or 4 foot polyethylene laminate safety netting) be installed at t he Drip Line or at the perimeter of the Critical Root Zone, whichever is greater, of significant trees/woodlands to be preserved. This tree protection fencing shall be installed on Lots 5, 6 and 8. Advisory Parks Commission Minutes of Regular Meeting of March 20, 2000 Page 2 4 Require that the applicant contact the City Forestry Division and set up a pre-construction site inspection at least five days prior to the issuance of the grading permit to ensure compliance with the approved Tree Preservation Plan and placement of the Tree Protection Fencing. 4 A cash dedication in lieu of on-site water quality ponding would be required for this development. 2. 1999 Metroenvironment Partnership Grant Recommend that the City Council accept the $33,070 grant from the Metropolitan Council to study the effectiveness of street sweeping to improve water quality in 2000 and 2001. 3. Orchard Heights Addition-Gonyea Development 4 This proposal would be subject to a cash parks dedication and a cash trails dedication. i Acknowledge that an individual lot tree preservation plan will be required for lots 5, 6, and 8 at the time of building permit application. Require that Tree Protective measures (i.e. orange colored silt fence or 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. This tree protection fencing shall be installed on lots 5, 6 and 8. Require that the applicant contact the City Forestry Division and set up a pre-construction site inspection at least five days prior to the issuance of the grading permit to ensure compliance with the approved Tree Preservation Plan and placement of the Tree Protection Fencing. A cash dedication in lieu of on-site water quality ponding would be required for this development. Member Petersen noted that the Commission would be discussing how the City can reduce impervious surfaces during a later agenda item. He suggested that the Slumberland development look at the potential of increasing the green space within their development. Member Davis asked if this could be a consideration in the Commission's review of the proposal. Director Vraa clarified that the Slumberland building is currently under construction but that they wanted to subdivide the lot to make room for further development potential. Member Davis asked if the Commission had had an opportunity to review this item previously. Planner Dudziak responded that this development received preliminary plan approval last year. The original plan showed two separate buildings for a total of 60,000 square feet and they were given approval for 2 buildings. The new plan with this subdivision provided for two, 35,000 square feet buildings. Member Rudolph asked if the two buildings increased the overall parking requirements. Dudziak responded that the increase in square footage results in additional parking needs. Member Davis asked if proof of parking was discussed. Planner Dudziak responded that that was not done and reiterated that there are no specific plans for the additional lot being created; they are planning to sell that property. Member Davis opined that there has been a tremendous amount of time spent on trying to reduce impervious surfaces in developments, noting that developers typically prefer smaller parking spaces. He asked if there was an opportunity to pursue reduced parking for this development. Planner Dudziak stated that Slumberland is pretty well underway but that could be an option for the easterly lot. Member Davis asked if the seed could be planted to reduce parking at the Slumberland site via proof of parking. Dudziak responded that perhaps a recommendation could be structured to have staff discuss this option with the developer. Daryle Petersen, expressing his hope that the Green Space recommendation would be approved by the Commission, made a motion that staff pursue with the developer a modification to the parking requirements to incorporate the opportunity for more green space for the Slumberland Addition. Terry Davis seconded the motion with all members voting in favor. Advisory Parks Commission Minutes of Regular Meeting of March 20, 2000 Page 3 Dorothy Peterson moved, John Rudolph seconded with all members voting in favor to recommend that this proposal be responsible for a cash parks dedication and a cash trails dedication. DEVELOPMENT PROPOSALS GLEN POND - LARRY WENZEL Following an introduction by Director Vraa, Planner Dudziak explained that this is a Planned Unit Development and development proposal for a four building apartment complex, and expansion of the current Glen Pond Apartments. This proposal provides for land exchange with the City to accommodate the future "ring road" through this area. The Commission will need to consider a park and trail dedication as well as the adequacy of the open space provided within the development. Planner Dudziak continued that this is a 228 unit extension of an existing apartment complex. She concluded that all parties appear to have worked to resolve the acquisitions require to pursue this development. Forestry Supervisor Hove reviewed tree preservation issues noting that there would be significant woodland removal (82.2%) in excess of allowable limits (47.5%). As the development is currently proposed, tree mitigation calculates to the installation of 131 category A trees or 262 Category B trees of 524 Category C trees. The submitted Tree Mitigation Plan indicates that 321 Category B trees will be installed on the total site. It was noted that the severed parcel to the south has been excluded from the mitigation plan and will be reviewed when development of this parcel is applied for. Hove continued that the proposed grading plan shows encroachment/grading extending approximately 30 feet into the preserved tree area in the northeast portion of the site. If the grade limits stay as presented, a revised tree mitigation plan would need to be submitted, adding 20 more Category B trees. Water Resources Coordinator Macbeth reviewed the water quality/wetland issues pertinent to this development. He addressed them as two separate parcels; north of the proposed Northwood Parkway and south of the proposed Northwood Parkway. The 10.64-acre portion to the north shows 38% as impervious and the 3.27 acres to the south shows an estimated 30% as impervious. Based on these assumptions, Macbeth continued, a minimum wet-pond volume of 1.25 acre-feet covering an area of .50 acres is required to treat stormwater generated by the entire 13.91 acre development Director Vraa reviewed the parks and trails issue noting that Moonshine Park is in this fairly fully developed park district. The master planning for Moonshine Park is just beginning, Vraa added. The closest parks to this proposed development are Pilot Knob and Country Home along with the future central park site, however each park requires the crossing of a major road. A cash parks dedication and cash trails dedication was recommended. In addition, Vraa noted that multi-residential developments are required to provide 300 square feet of open space for each unit. This proposal shows two areas; one small centrally located 4,800 square foot space planned to include a tot lot. The second area is 42,800 square feet to the northeast with significant slopes down to a pond. The slopes do limit the use of this space for most uses typical of play and the pond divides the open space, further reducing its usefulness, Vraa concluded. Dick Krom, architect for the project stated that this has been a very lengthy process to date. He noted the developer is satisfied with the water quality/wetland issues raised but takes exception to the designation of significant woodlands and the mitigation required. He added that they view this area as second growth trees and that the mitigation equates to approximately $100,000. It was noted that most mature trees are around the wetlands to the south and the developer will be working to preserve more of these when it is time. He expressed concern by the developer in general for the tree mitigation. Advisory Parks Commission Minutes of Regular Meeting of March 20, 2000 Page 4 Mr. Krom added that they did not define the specifics of the recreational area, they simply identified the 42,000 square foot area. Their preference would be to see how the residents want to use the space rather than throw dollars into facilities that may not be used or fit the residents' needs. Member Rudolph noted that the Tree Preservation Plan specifically identifies significant woodlands and to change that designation in this case would be setting a dangerous precedent. He added that he walked the parcel and the proposed recreation area is a low-land slough and can't see this being used as a recreational space. Member Peterson added that she, too, had walked the site and has some concerns for the pond separating the recreational area, leaving it relatively unusable. Member Rudolph asked what the timeline was for construction. Mr. Krom responded that they are hoping to begin in late spring/early summer. Member Johnson asked if the tot lot is surrounded by a parking lot. Mr. Krom responded that it was placed in this location because of the visibility from the buildings to the play structures. Director Vraa added that the location does have good visibility from all buildings and is centrally located, however it is close to traffic. Member Rudolph asked if the proposal was approved as presented would there be an updated landscape plan brought back to the Commission. Director Vraa stated that staff typically handles the landscape plan review. Member Davis expressed concern for the lack of flat recreational space and asked how much there would be. Mr. Krom stated that if the Commission is looking for a flat area for an athletic field, that would not happen on this site. Rather, the recreational space is provided as more of an open play area. Mr. Krom also noted that there would be other recreational areas available on this site. Following further discussion, Barbara Johnson moved, Joseph Bari seconded with all members voting in favor to recommend that the City Council approve the preliminary plat and PUD for Glen Pond subject to the following conditions: 4 Require that a cash parks dedication and a cash trails dedication be met. 4 Require that the developer provide sufficient flat, grass space to provide for informal recreation opportunities. 4 Require that the applicant install 131 Category A trees or 262 Category B trees of 524 Category C trees, or an equivalent combination of these trees as mitigation for tree removal in excess of allowable limits. Mitigation shall be in addition to any City required landscaping. 4 Require that a revised Tree Mitigation Plan be submitted that shows the correct amount and species of mitigation trees. 4 Require that the grading plan be revised to eliminate encroachment into tree preservation areas. 4 Require that Tree Protective measures (i.e. orange colored silt fence of 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. 4 Require that the applicant contact the City Forestry Division and set up a pre-construction site inspection at least five days prior to the issuance of the grading permit to ensure compliance with the approved Tree Preservation Plan and placement of the Tree Protection Fencing. 4 Require that a maximum 40 percent of the 10.64 acre portion of the proposed development, located north of the future Northwood Parkway, will be impervious. 4 Require that a maximum 30 percent of the remaining 3.27 acres of the development (the "severed parcel" south of the future Northwood Parkway) will be impervious. Advisory Parks Commission Minutes of Regular Meeting of March 20, 2000 Page 5 1; Require that water quality requirements will be met through creation of a treatment pond (using NURP standards) with a minimum wet-pond volume of 1.25 acre-feet covering an area of 0.50 acres. The pond will have a 10:1 slope for the first foot of depth below normal water level and a 3:1 slope for the remainder to a maximum depth of 4 feet. 4 Require that there will be no activities or impacts within the delineated boundary of wetland "A". 4 Require that no excavation or grading associated with creation of the treatment pond will occur before the easements of wetlands "A" and "B", as defined in Exhibit A of the wetland delineation report, are clearly marked in the field and before authorization by the Corps of Engineers through Section 404 authority. 1; Require that the maximum grading impact associated with the easement of wetland "A" will be 1,500 square feet. 4 Require that the maximum grading impact associated with the easement of wetland "B" will be 5,500 square feet. 4 Requires that any significant changes to these conditions should warrant an additional review of this development, 1; Final tree mitigation issues are to be worked out with staff. OLD BUSINESS CEDARVALE UPDATE Member Rudolph provided a brief update of the Village Plaza redevelopment concept reviewed by the City Council. He noted that the priority for redevelopment is to locate the road(s) with the building(s) to follow. He added that the Commission is a great ally to the City Council regarding the green space on the site. Although the planning for this project is moving along, Rudolph added that the greatest issue will be how it is financed. Rudolph added that staff has done an exceptional amount of work with this project. Member Bari asked what the proposed timetable was for road construction. Member Rudolph responded that the first phase proposal was expected within the next 1-6 years. Member Davis added that there will be a special meeting on Tuesday, April 11 at 5:00 p.m. with the City Council regarding this issue. GREENSPACE TASK FORCE REPORT Member Davis noted that the Green Space Committee, comprised of various members of the Advisory Parks Commission, Advisory Planning Commission, City Staff and Eagan citizens, have met 3 times as a joint committee. Their recommendations suggest that the following Code amendments be considered in the interest of preserving green space within the City: © Establish a minimum green area requirement for commercial and industrial users. ® Reduce parking stall dimensional requirements for retail commercial users. © Revise parking supply requirements for retail commercial and office uses. In addition to reviewing the issues, the committee created models of existing sites and how implementation of the above requirements could have changed them. Member Petersen added that the recommendations by the Green Space Committee are pretty typical with other communities in the metro area and nationwide. He opined that this is a win/win situation for developers as well. Advisory Parks Commission Minutes of Regular Meeting of March 20, 2000 Page 6 With further brief discussion, John Rudolph moved, Dorothy Peterson seconded a motion that the pro- active recommendations made by the Green Space Committee be forwarded to the City Council for consideration and approval. Member Filipi asked if reducing the parking stall size would be mandatory rather than voluntary. Member Davis responded that the attempt was to allow flexibility in meeting the green space requirement. It was felt that this would allow staff to work with developers to maintain the 30% green space requirement. Member Peterson asked how long it would take to have this ordinance put in place. Director Vraa responded that the City Council would need to have a workshop to review this issue and that it typically takes 60-90 days from the time the Council chooses to proceed. Member Hiar expressed concern for shrinking the parking stall size given the size of many vehicles used today. He opined that perhaps too many parking stalls are being required for developments and suggested looking at their uses. Member Davis responded that the recommendations are not only tied to the size of the stalls but to the usage. Member Petersen added that the key to the success of the recommendations is to increase the green space by offering several options for developers/staff to consider. Member Rudolph opined that the requirement for green space will bring about a more aggressive use of proof of parking. Following further brief discussion, the motion was called. All members voted in favor. NEW BUSINESS SENIORS SURVEY Director Vraa provided a brief background noting that considering the expected growth of seniors and the current offerings by the Department, it was decided there needed to be some type of information collection to determine the future needs and interests of this population. The Recreation Subcommittee reviewed the draft survey in February for changes. The intent of the survey was to seek ideas from seniors for recreational opportunities. Recreation Supervisor Bolduc stated that the final draft of the questionnaire would be sent to approximately 900+ seniors currently on the Department's mailing list. She reviewed the questionnaire briefly and solicited input from the Commission. Member Johnson suggested that the final results of the survey be placed on cable TV and asked if another font could be considered for the questionnaire. Member Davis commented that the size of the font seemed appropriate, however. Member Peterson asked if there would be a question regarding the proposed community center. Director Vraa noted that the questionnaire will be returned after the City Council's review of a potential building and suggested that input from seniors would be more effective at a later date when a community center becomes more of a reality. Member Rudolph opined that the data base will be helpful given the potential of a community center. Member Davis concurred with Member Johnson's comment that the results should be shared with the community once they're completed. Member Filipi asked if the questionnaire could reach a broader audience. Member Petersen suggested placing an announcement in the paper making forms available to seniors not on the mailing list. Member Davis asked if there would be a way to determine where seniors are currently going for activities. Advisory Parks Commission Minutes of Regular Meeting of March 20, 2000 Page 7 Member Peterson asked Supervisor Bolduc what information she was trying to glean from this group. Supervisor Bolduc responded that she was attempting to focus on what services are currently offered and what interests they have that should be pursued. Director Vraa added that based on the community survey for the central park, people will take the opportunity to express their opinions and interests even if they are not specifically listed on the survey form. Following further brief discussion, Barbara Johnson moved and Terry Davis seconded a motion to approve the Senior Survey as written and forward it to the current seniors list. Member Davis amended the motion to include a question clarifying where seniors are currently attending activities geared for their population, if staff determines that to be appropriate. All members voted in favor of the motion. PLAYWAGON RECOMMENDATION Director Vraa introduced this item and provided a brief background. Recreation Supervisor Nowariak noted that the Recreation staff and Recreation subcommittee met to review this item. The proposal is to consider alternative uses and modification to the existing Playwagon to increase its versatility for expanded program opportunities. Supervisor Nowariak identified multiple potential uses for the vehicle if the modifications were completed including use by the Arts and Humanities Council to bring art programs and experiences to the community via an "artmobile". It was noted that the Arts and Humanities Council has submitted a grant to provide funding to carry out their vision and use of the trailer. Member Peterson noted that the Playwagon was built in 1980 with the original intended use to be for a puppet theater. Member Rudolph noted that it was a great application for a "mobile park". John Rudolph moved, Barbara Johnson seconded with all members voting in favor to recommend the allocation of $4,200 for renovation to the Playwagon to be funded through the "small project' 'category of the Park Site Fund. LAND ACQUISITION PROPOSAL - PATRICK EAGAN PARK Director Vraa introduced this item noting that the Goetzs have offered to sell a 1.2-acre parcel of land adjacent to Patrick Eagan Park for $25,000. Mr. Goetz recently sought to split his lot for construction of another home site and in doing so, various area wide assessments typically associated with development will be incurred. As a means to reduce assessments, he is offering to sell a portion of his property to the City of Eagan. Director Vraa shared the location of the site in relation to Patrick Eagan Park and Berry Patch Park, noting the location of a potential trail connection between the two. The photos of the site showed the mature trees and wetland. A topography map was also shared with the Commission. Director Vraa concluded that if the Commission chooses to proceed with the acquisition of this property they will also need to identify where the funds will come from. Mr. Goetz addressed the Commission and thanked them for the opportunity of hearing their proposal. He then shared the layout of the site and plans to build another home on the newly created lot while selling the existing home and lot. During their meeting with the City Council, Mr. Goetz stated that the Council suggested they look at the option of swapping land in lieu of some of the assessment fees that would be due. He added that the asking price of the land is approximately the same as the fees being charged. The Goetzs felt that this would be a great opportunity for the City to preserve this beautiful wooded area adjacent to Patrick Eagan Park. Mr. Goetz then shared photos they had taken of the parcel. He also noted that in order to connect a trail between Berry Patch Park and Patrick Eagan Park easements would need to be acquired from the property owners. Advisory Parks Commission Minutes of Regular Meeting of March 20, 2000 Page 8 Member Rudolph noted that he visited the site and could understand why the Goetzs want to preserve it; it is a beautiful site. Member Petersen asked if the City were to acquire the parcel, couldn't the fees be waived in exchange for the property in lieu of purchase. Director Vraa clarified that if the City were to acquire property the funds would need to come from somewhere. Member Peterson concurred with the beauty of the site and recognized the value of preserving woodlands. She added that if this parcel were on the north side of Deerwood Drive she would agree that it would be an important acquisition and link to Patrick Eagan Park. Member Petersen stated that the Commission sometimes struggles with what to do with dollars from the Tree Mitigation Fund and suggested that this could be an option. Member Davis referenced the parks Master Plan noting that this parcel was not a part of the overall plan for acquisition. Member Ban added that since there is no master plan for Patrick Eagan Park, this 1.2 acre parcel would simply be added to the existing 105 acre site. Bari added that the additional acre would not have as significant an impact as it may adjacent to another park property. Mr. Goetz responded that it would provide a great opportunity too preserve the parcel of land in the long run. Member Filipi asked about easement requirements from property owners to the west. Director Vraa stated that staff has not approached those homeowners to see what their interest may be. Member asked what the timing for this proposal was. Mr. Goetz responded that they are trying to take this back to the City Council on April 4 and that the Council directed them to go before the Advisory Parks Commission for consideration of acquisition. Member Petersen asked if the acquisition would be more amenable if a trailway connection could be made between Berry Patch Park and Patrick Eagan Park. Member Rudolph stated that would require easements from two other property owners. Mr. Goetz suggested that the connection could be made with an easement from only one adjacent property owner. Member Petersen empathized with the situation but expressed the need for theCommission to fully review this issue before passing a recommendation to the City Council. Mr. Goetz suggested that the Commission look beyond the trail issue and consider this parcel for preservation purposes. Member Davis concurred with Member Petersen's comments to ensure the understanding of all the information before making a recommendation. Joseph Bari moved, Terry Davis seconded a motion to defer this item to the Acquisition/Development subcommittee for further review and recommendation. Noting that this item will be appearing at the April 4 City Council meeting, it was suggested that there might not be sufficient time for the sub-committee to review this issue, bring it back to the Commission for action prior to the City Council review. The motion was withdrawn. A special Commission meeting was set for April 3, 5:00 p.m. for the whole Commission to meet, visit the site and then take action prior to this item appearing on the April 4 City Council agenda. The special Commission meeting would include notification to the newspapers and posting of the agenda for the public. RAHN PARK CELL TOWER Following a brief introduction by Director Vraa, Superintendent Olson noted that U.S. West is requesting permission to install six antennas and a ground based power cabinet on an existing NSP transmission tower in Rahn Park. Olson shared the site plan and photos identifying the location of the existing tower and proposed ground equipment. It was noted that the Lexington Diffley site has a ground equipment setup and there have been no issues with its installation. Advisory Parks Commission Minutes of Regular Meeting of March 20, 2000 Page 9 Member Peterson asked if there were any other park sites that were being considered for antenna installation. Superintendent Olson stated this was the only proposal he was aware of. Olson then responded to a question regarding the type of fencing that would be provided around the ground equipment noting that staff would work with NSP relative to the fencing and landscaping around the area. Member Davis asked why a fence was needed. Superintendent Olson responded that since this tower is close to the Highline Trail, there might be the need to prevent children from getting into the area. Member Davis opined that if there isn't a concern for children climbing on the towers there may not be a need for a fence. Member Rudolph asked who determines the need for fencing. Superintendent Olson stated that the City would make the request for a fence and U.S. West would supply a plan for review. Member Davis opined that if the purpose for fencing is to prevent damage to the equipment, that is not the City's issue; it is U.S. West's. Following further brief discussion, John Rudolph moved, Dorothy Peterson seconded with all members voting in favor to recommend approval of the lease request made by US West to use City park property for the installation of cellular antennas and a ground level power cabinet, subject to the terms and conditions of the standard City of Eagan telecommunications lease. In addition the Leasee shall be required to install a City approved security fence and landscape screen compatible with park surroundings. Dorothy Peterson moved, John Rudolph seconded with all members voting in favor to recommend to the City Council that the rental fees collected in 2000 for antennas that are installed in park settings be dedicated to the purchase of properties not previously approved for acquisition in the Park Site Fund. PARKS AND RECREATION UPDATE Superintendent Olson noted that April 4 is the only time when requests to add/delete snow plowing routes.

Olson added that a job fair would be held on March 23 to recruit seasonal staff and concluded that street sweeping has begun throughout the City.
