AGENDA Ted Billy moved, Jonathan Wdem seconded with all members voting in favor to accept the agenda as presented. MINUTES OF REGULAR MEETING OF APRIL 2, 1992 Erin Ipsen moved, Kevin Knight seconded with all members voting in favor to accept the minutes as presented. CONSENT AGENDA It was noted that there were no Consent Agenda items to review. LEXINGTON POINTE 8TH ADDITION - JAMES A. CURRY Stephen Sullivan introduced this item as a Comprehensive Guide Plan Amendment from Commercial Planned Development to D-1 Single Family and the rezoning of approximately 80 acres from Community Shopping Center to R-1 Residential along with the preliminary platting of 167 single family lots. Steve continued that this parcel is part of the Lexington South Planned Development located south of Co. Rd. #30, east of Co. Rd. #43, north of Walnut Hill Park and west of the Lexington Pointe subdivision. It was noted that the perpetual residential down zoning has resulted in additional residents within Park Service Area #26 currently served by Walnut Hill neighborhood park. Trapp Farm Park and the Highline Corridor also provide a complimentary level of service. The build-out of this P.S.A is approximately 4700 with the entire population being within 3/4 mile of the two identified parks. Therefore, a cash parks dedication was recommended. Relative to the trail dedication, Mr. Sullivan explained that the original Planned Development Agreement required that trails be installed and their costs borne by the developer, however, continued revisions to the PD has resulted in an amended agreement requiring plats to no longer install trails, but to pay a cash trails dedication. The plat is also responsible for providing a north/south corridor from Daniel Drive to the Highline Corridor with the escrow money already provided by Tri-Land Development for this trail link. The current proposal indicates an 8' bituminous trail alignment running from Daniel Drive, along the south side of Eagan Center Road to an outlot between lots 46/47. This corridor continues in a landscape median of Pointe Esplanade to Lexington Pointe Parkway. Crossing Lexington Pointe Parkway, it continues easterly within the southern boulevard where it traverses south along a pond, terminating at the Highline Corridor. Staff is recommending that the proposed 8' bituminous trail located within the north boulevard of Lexington Pointe Parkway should be relocated to the south boulevard. This trail alignment provides a continuous trailway along the roadway from Lexington Avenue to the Highline Corridor. The City's Engineering Department is requesting the road access to the lots south of Lexington Pointe Parkway ADVISORY PARKS, RECREATION AND NATURAL RESOUCES COMMISSION MINUTES OF MAY 7, 1992 MEETING PAGE 2 be relocated and aligned with Pointe Esplanade Road and Parks staff feels this realignment, in conjunction with a four-way stop, would facilitate a safer pedestrian crossing. Steve continued that staff met with the developer regarding tree preservation on the site and the developer has been open to looking at how to best accommodate this request. Rich Brasch reviewed the water quality issues noting that storm water runoff from about 54 acres of the Lexington Pointe-8th Addition development will drain to JP-50 under the proposed storm sewer configuration. The remaining 16 acres will drain offsite around the edges of the development. 16.8 acres of the Lexington Pointe-3rd Addition off the southeast corner of the 8th Addition presently drains to Pond JP-50 and can be treated once the pond is completed. In order to meet treatment obligations for the platted single family residential area within the Lexington Pointe-8th Addition credit could be given to the developer for using JP-50 to treat runoff from the "grandfathered" 3rd Addition to make up for area in the 8th Addition that can not be intercepted by JP-50. Jack Johnson expressed his concern for the crossing at Lexington Pointe Parkway and Pointe Esplanade Road suggesting that protection needs to be provided at this intersection. Steve Sullivan responded that staff concurs with a four-way stop at this intersection. After further discussion, Ted Billy moved, Kevin Knight seconded with all members voting in favor to make the following recommendations to the City Council regarding Lexington Pointe 8th Addition. 1. That the plat be subject to a cash trailway dedication. 2. That the plat be subject to a cash park dedication. 3. That the proposed 8 foot bituminous trail located within the north boulevard of Lexington Pointe Boulevard be relocated to the south boulevard. 4. That the road access to the lots south of Lexington Pointe Parkway be relocated and aligned with Pointe Esplande Road. A four (4) way stop with cross walks and pedestrian ramp should be implemented at this proposed intersection. 5. The development shall be responsible for grading a 10 foot wide trail pad, providing an all pedestrian ramp, and assuring no encumbrances within the pedestrian corridor. Trail gradients and pedestrian ramps shall meet ADA design requirements. 6. The applicant will be responsible in a coordinated effort with the City for the installation of trails. 7. The development is to be evaluated and revised to maximize tree preservation of the oak and maple woodland areas. These preservation efforts to be reviewed and approved by staff prior to final plat. The developer will also be responsible for submitting a tree protection plan prior to final plat. 8. The development shall meet its water quality treatment requirement by constructing an on- site pond to treat runoff from the proposed single family residential development. The storm system layout and pond design must be approved by City staff prior to final plat. ADVISORY PARKS, RECREATION AND NATURAL RESOURCES COMMISSION MINUTES OF MAY 7, 1992 METING PAGE 3 LAKEVIEW TRAIL ADDITION Stephen Sullivan introduced this item as an application requesting the rezoning of 19.64 acres from Agricultural to R-1 Single Family and the preliminary platting of 37 lots. This parcel is located south of Manor Lake Addition, west of State Highway 3 and east of Dodd Road. Steve continued that Park Service Area #36 was evaluated with the platting of the Manor Lake Addition at which time the Commission recommended that Manor Lake provide a land dedication of approximately 2.6 acres and the rough grading of the parkland. The Commission anticipated a future parkland dedication of approximately 2 acres from the Lakeview Trail Addition. The parkland dedication with the Manor Lake subdivision equates to 1.94 acres and the current proposal provides 1.54 acres for parkland. Steve added that the .40 acre short fall of land equates to a cash equivalent of $5,195.87 and would also be subject to a cash trails dedication. Rich Brasch reviewed the water quality issues noting that the development is located in the upper reach of drainage basin L and borders the north shore of pond LP-26, a Class II lake intended to have water quality sufficient to support indirect contact recreation activities. Rich continued that on-site ponding to meet treatment requirements for the remaining 14.4 acres of the site is both feasible and desirable. It is anticipated that two ponds would be built on-site; one located on lot 16 and 17 and treat run-off from about 6.3 acres of the site before discharging to Pond LP-26, and the second to be located in the northeast corner of the site to treat run-off from approximately 3.5 acres of the Lakeview Trails Addition as well as 3 acres of the Manor Lake 3rd and 4th Addition. Mr. Brasch concluded that this particular area of the city has a high level of high quality water bodies. Jack Johnson expressed concern for the grassy area that will need to be graded and the need to provide for quick re-establishment of the grass on this site. Mr. Johnson asked if the water could be re- routed to another pond. Mr. Brasch answered that substantial re-grading would need to occur on the western portion of the development to allow for this option. He added that this option could prove to be very costly for the developer. Mr. Johnson asked that this, or other options, be considered as alternatives for this site. Mr. Brasch added that the developer did not own the land to the west of the site making ponding in this location a difficult option. After further discussion, Ted Billy moved, Erin Ipsen seconded with all members voting in favor to make the following recommendations to the City Council regarding Lakeview Trail Addition: 1. That the plat be responsible for a parkland contribution of 1.54 acres as configured by the site plan dated March 16, 1992. 2. That the plat be responsible for a cash park dedication of $5,195.87. The dedication may, at the discretion of staff, be applied to parks grading with the terms of the grading to be worked out between staff and developer. 3. The plat be responsible for a cash trails dedication of $3,700.00. 4. That this development meet its water quality treatment requirements by creating two treatment ponds on-site. The storm sewer layout and pond design should be reviewed an approved by City staff prior to final plat. The two acre drainage concern expressed by staff is to be reviewed by staff to include an option for overland drainage. ADVISORY PARKS, RECREATION AND NATURAL RESOURCES COMMISSION MINUTES OF MAY 7, 1992 MEETING PAGE 4 INDEPENDENT SCHOOL DISTRICT 196 - DEERWOOD SCHOOL 2ND ADDITION Parks Planner Stephen Sullivan introduced this item as a request to rezone 23.5 acres from Agricultural to Public Facilities and the Preliminary Platting of one lot for a middle school on a parcel located south of Deerwood Drive and west of Deerwood Elementary School. Some of the issues for the Commission to review included determining the parks and trails dedication and discussion the impact to the woodland resource. Steve stated that public facilities are not obligated to provide park dedication. Relative to the trails dedication issue, an existing trail lies within the southern boulevard of Deerwood Drive. Since this parcel did not participate in the cost of the trails, staff recommended this proposal be subject to a cash trails dedication. The parcel contains approximately 2.3 acres of significant woodlands adjacent to Deerwood Drive around a small pond. The tree survey provided by the School District indicates a predominance of oaks ranging in size from 12" to 40" in diameter. Steve continued that the existing grading plan indicates no preservation of the existing woodland and pond given the School District's need for athletic playing fields. The proposal is to relocate the pond within an area that cannot support athletic play fields. Water Quality Coordinator Brasch reviewed the water quality issues relative to this proposal. He continued that in order to fully meet treatment requirements the proposed pond would need to be .57 acres in surface area and have a wet volume of 2.25 acre-feet at the normal water elevation. Because site constraints limit the size of the proposed on-site pond to .45 acres and approximately 1.6 acre-feet, a treatment deficiency exists. In respect to the wetlands, Mr. Brasch stated that the inventory indicates that three wetlands with a total acreage- of .44 acres would be filled as a result of development. The first Res in the southwest corner of the parcel and is identified as a Type 2 wet meadow of .12 acres in area. The second wetland lies off the southwest corner of Deerwood Elementary. School identified as a Type 1 bottomland hardwood forest. The third wetland located south of Deerwood Drive in the north central area of the site is identified as a Type 2 wet meadow with a narrow fringe of Type 1 bottomland hardwood forest. The developer is proposing to fill all three wetlands totaling .44 surface acres. Mr. Brasch concluded that the use of the treatment pond proposed for the northeast comer of the site is allowable for wetland replacement purposes under the Wetlands Conservation Act - Interim Program. To the extent that the surface area of the proposed treatment pond equals or exceeds .44 acres in surface area, the wetlands replacement requirement can be met by the treatment pond. Director Vraa added that the Commission has looked at a joint school/city facility option for this site in the past but it appeared not to be a viable option based on the facilities needed by the School District and the limited area in which to develop those facilities on this site. Lee Markell expressed his concern for the proposed filling of the wetlands and asked if there was any possibility of tree preservation on the site. Steve Sullivan responded that tree preservation was not an option based on the facility layout and grading plan. Director Vraa asked the School District's representative if it would be possible to relocate some of the plant material if there was going to be significant tree loss. A representative of Wold indicated that there would be no objection to that option and that the School District would be working at buffering to mitigate some of the impact. Mr. Markell asked what the schedule was for the development of this site. Wold indicated that grading would begin after school was out hoping that the facilities would be ready for fall, 1992. Construction of the building would begin in the fall as well. ADVISORY PARKS, RECREATION AND NATURAL RESOURCES COMMISSION MINUTES OF MAY 7, 1992 MEETING PAGE 5 Deborah Johnson stated she understood making the wetland replacements but was very disappointed that these valuable resources would need to be compromised. Lee Markell added that a private housing developer would not have been allowed to compromise the wetlands and trees and asked what other options the Commission could consider. Lee suggested that an option to be considered would be that the wooded area be used as a nature area in conjunction with other school programs before the plan is approved. After considerable discussion Lee Markell moved that the plat be responsible for a cash trails dedication; that the school district take a closer look at preserving the area south of Deerwood consisting of a depression surrounded by trees as a possible outdoor education area that could be in with the ball fields and athletic fields and that the school district consider looking for additional land acquisition. Mr. Markell explained the intent of the motion was designed to have the district look at environmental education as an important part of the students curriculum - as important as the need for playfield/physical education needs. After further discussion, Deborah Johnson seconded the motion. The motion passed by a vote of 6-1 with Jack Johnson voting against. PROPOSED REGULATIONS TO CONTROL IMPACTS TO BOULEVARD AND TRAIL AREAS Superintendent of Parks VonDeLinde introduced this item noting that city staff had raised concerns over the impacts that certain developments were having on trails and boulevard areas within the City of Eagan. These concerns were primarily related to contractors using the boulevard areas as an ingress/egress point to construction sites, and erosion and siltation onto trail surfaces. The result of these concerns was the formation of a committee to further investigate these and other impacts to boulevard areas, along with proposed regulations for protecting the city's trails infrastructure. The four issues that were identified included 1) Driving and parking on city trails. 2) Utility construction/reconstruction. 3) Vehicular access across boulevard and 4) Erosion/siltation. John then reviewed each item and the proposed series of changes to the city's regulatory instruments made by the committee which included modifications and additions to the City Ordinance, development of a new public utility maintenance vehicle permit and changes and additions to the city's right-of-way construction permit. After considerable discussion, Kevin Knight moved, Lee Markell seconded with all members voting in favor to accept the changes in the proposed regulations to control impacts to boulevard and trail areas in the City of Eagan as proposed by staff. PROPOSED SCHWANZ LAKE WATER QUALITY IMPROVEMENT PLAN Rich Brasch explained that in 1989 the City applied for a grant through the Minnesota Pollution Control Agency's Cleanwater Partnership Program to develop a strategy to combat water quality degradation in Schwanz Lake located in Trapp Farm Park which is one of the most intensely used parks in the city. Of the estimated cost for the study ($74,000) half was paid for by the Cleanwater Partnership Grant from PCA with the remaining costs being covered through a combination of in-kind services performed by City staff and City cash contributions. Mr. Brasch outlined the major work elements of the project noting that one year was spent on these items culminating in the selection of remedial alternatives and completion of implementation plan. Rich reviewed a table outlining preliminary treatment alternatives for Schwanz Lake. After significant discussion the Commission felt the priorities for the structural alternatives would be to enlarge pond LP-32.1, Construct ADVISORY PARKS, RECREATION AND NATURAL RESOURCES COMMISSION MINUTES OF MAY 7, 1992 MEETING PAGE 6 park basin and create lift station bay. Rich also reviewed all the cost implications for these options. Mr. Brasch noted that when the city is successful at improving the water quality of this highly classified water body, the lake can then be stocked. Jack Johnson thanked Rich for the in-depth information and options that need to be considered. He suggested' looking at all options and deciding which ones would be the best options for the dollars allocated. HAWTHORNE WOODS UPDATE Parks Planner Sullivan reminded the Commission that they had reviewed this development at the February, 1992 meeting where the developer proposed a pad grading approach but intended to evaluate lot specific tree preservation once road center lines were staked. Steve continued that the developers sensitive site planning and lot specific tree preservation minimized the unnecessary loss of the woodland resource within this residential subdivision. Lee Markell suggested that a letter be drafted on behalf of the Commission commending the developer for tree preservation within their development. DEPARTMENT HAPPENINGS Superintendent of Recreation Peterson reviewed several Happenings items including the upcoming Eagan Fun Run; the field space allocation identified for EAA baseball and softball; the first soccer tournament planned for Memorial week-end and the Region 1AA girls fast pitch softball tournament to be played at Northview. ICE ARENAISWIMMING POOL UPDATE Director Vraa stated that seven people attended the first informational meeting held regarding the ice arena/pool. He continued that the cable presentation that has been showing may have been seen by enough people to have provided the information they were looking for. ROUND TABLE Jack Johnson commented on the EHS Football Booster Club fertilizer sale throughout the community stating he was pleased to see one of the fertilizers offered had zero phosphorous content. Mr. Johnson suggested that a letter be drafted on behalf of the Commission to the Booster Club to thank them for their support of no phosphorous fertilizer. With no further business to conduct Erin Ipsen moved, Lee Markell seconded with all members voting in favor to adjourn the meeting. The meeting was adjourned at 10:20 PM. 3 42 S cretaryDate
