MOTION: Clinton moved, seconded by Wissner to approve the Agenda as published. Motion carried 4-0-0. IV. MEMBERS REPORTS Kardell reported that the housing goals and recommendations would be presented to the City Council at their March lb, 1993 meeting. V. MINUTES VI. PUBLIC HEARINGS A. VILLAGE KNOLLS 2ND ADDITION by Wooddale Builders. Request for PUD Concept and PUD District Review with waivers on 19.1 acres, Zoning District Amendment in the existing R1-13.5 Zoning District on 19.1 acres, and Preliminary Plat of 19.1 acres into 44 single family lots. Location: East of the Intersection of Homeward Hills Road and Silverwood Drive adjacent to Purgatory Creek. Franzen reported that the Village Knolls project had been approved 2 years ago and because of concern regarding the area next to Purgatory Creek a PUD was required on the balance of the property. A grading and utility plan were approved. The original recommendation was that no Shoreland Ordinance variances would be needed. The plans being presented tonight are the 19 1 detailed plans for Phase H. The plan is similar to the original with less tree loss and one less lot. Randy Hedlund, Hedlund Engineering, presented the plans for the 44 lot subdivision. Lot 16, Block 2 was combined from 2 lots into 1 lot and some of the lots were widened. The overall tree loss is 12%. Some significant oak trees would be lost. The proposal has the same layout as approved before. The builder proposes to construct the development in two phases with the first phase to begin this spring if the plan was approved. Hedlund stated that rear yard storm sewer systems would be installed to handle the run-off from the homes. Hedlund stated all of the homes would be full walkouts with the exception of the two corner lots which would be daylight window homes. He added that Phase 2 would also be full walkouts with the two corner lots being daylight window homes. The slopes to the creek are 3 to 1. There will be no utility construction within the creek bottom area. Schlampp asked if the storm water outlet would be a 42" outlet. Schlampp noted that if this plan were approved today a N.U.R.P. pond would be required. Schlampp was concerned about erosion washout going into Purgatory Creek. He was also concerned about the steep slopes in Phase I. Schlampp noted that Lots 1 and 2 did not have storm drains. Hedlund replied that Lot 16 would drain directly into a catch basin. Schlampp was concerned about two driveways being created on an already busy street. The driveways for Phase II, Lots 1 and 2 would also create more curb cuts. Schlampp noted that Phase II, Lots 1 and 2 had been under water during the 1965 floor because the land is very low in this area. Hedlund replied that the walkouts were proposed to be 20 feet above flood level. Steve Schwieters, builder for the project believed that some improvements had been made to the culvert system in this area. Schlampp believed that the same 24" culvert directed the water under Homeward Hills Road. Franzen reported the property was rezoned single family in 1977 with only a small portion being platted. The plan meets City Code requirements. Franzen noted that 2 variances for street frontage would be required. Franzen added that these variances had been identified at the time when the original plan was proposed. The project meets Shoreland Ordinance requirements. The 12% tree loss is low; the average tree loss for projects is 30%. Franzen stated that some of the lots along Homeward Hills Road would require a significant amount of fill. Reforestation would be required along the creek corridor. A sidewalk would be located along one side of Chesholm Drive. Franzen reported that some concern from neighbors had been expressed regarding the trail next to the area along the creek corridor. Franzen noted that a turn-around area would typically be required for Lots 1 and 2 which have the direct access onto Homeward Hills Road. Clinton asked for clarification on allowing the construction of homes on the 16 lots which are in the "no build" Conservancy Area. Franzen spoke to the philosophy of the Purgatory Creek master plan and that development adjacent to the creek has been negotiated and the conservancy area doesn't have a legal basis. He added that the greatest encroachment would be along Homeward Hills Road. Franzen believed that there would be enough area between the creek and the grading area where natural vegetation would still be seen. 40 2 Norm Ziesman, 10087 Horseshoe Trail, stated that currently a silt fence exists along his lot. He • noted that his sod had washed away 3 times and would be replaced again this spring for the 4th time. Ziesman said that erosion is a serious problem in this area. Ziesman stated that he was not against the development but, wanted protection against further erosion problems from the development. Hedlund replied that the contours would be lower than the current property line and the new lot would be graded lower than the existing lot. The hill in this area would be taken down. Ziesman said that if he understood the plan correctly then he would not be looking up at the new homes but they would be more level with his home. Ziesman was concerned about the speed of the traffic along Homeward Hills Road which he believe to be between 40 and 45 MPH. Ziesman asked if there was any way to reduce the speed so that the children in the neighborhood could have safe access to the park. Ziesman stated that he had a child in a wheelchair and asked if safe access could be provided to the park for the handicap. Kardell asked if curb cuts could be made so that wheelchair access would be available to the park. Franzen replied that he would communicate this request to Park&Recreation Department. Kardell asked if the Planning Commission should make a reference in the recommendations for the request. Franzen replied that it would be helpful for the Planning Commission to also voice the request. Kardell encouraged the neighbors present this evening to also attend the City Council meeting and make their concerns know and to also contact the Police Department regarding the speed of the cars in the neighborhood. Kardell noted that the Planning Commission could not regulate the speed limit for additions. Wissner asked if a traffic study had been done on this road lately. Franzen replied no, but that • collector roads in Eden Prairie are designed based on guide plan density and that this project is less dense than the guide plan, so from a capacity standpoint Homeward Hills road can handle the traffic volume. Franzen suggested that additional catch basins could be recommended if the water did not flow off the property quickly to help control the erosion problem. Ziesman believed that the hill being taken away would also help the erosion problem. Kathy Marcotte, 19965 Runnel Circle, asked what the plans were for the area for the creek corridor next to Lot 1. Hedlund replied that the bridge would not change. An 8-foot bituminous trail would be developed along the outlot. Hedlund stated that the existing culvert pipe would be extended out past the rear lot line for Lot 1. Hedlund noted that the trail could not be constructed without the extension of the culvert pipe. Schlampp stated that this area of the creek corridor was a large wetland area. Marcotte asked if trees would be taken out in the corridor area. Hedlund replied that no trees would be impacted beyond the property line. Marianne Fielder, 19975 Runnel Circle, stated that a tributary from the creek runs under the culvert. She added that this area was very wooded and created a natural barrier because of the large trees and bushes. Fielder was concerned that only a small row of trees would be left standing. Fielder believed that the extension of the culvert would only add to the speed of the 3 water flow. Fielder stated that she would like to see as much of this area preserved as possible. Fielder recommended that the home on Lot 1 be moved back as far away from the lot line next to the corridor as possible. Fielder believed that a bike trail could still be built. She added that the trees provided a natural wind break. Fielder noted that the homes along the tributary pay creek taxes for easements. Fielder presented a picture of what the wetland area looked like after a rain. Hedlund asked Fielder if the culvert was draining water from the park. Fielder replied yes. Hedlund replied that he did not believe that shifting a lot line would help anything. Hedlund asked Schwieters what the price range was expected for the homes. Schwieters replied the homes would range from $325,000 to $450,000 along the creek area and $260,000 in the other areas. Schwieters asked Hedlund how many feet the culvert would be extended. Hedlund replied approximately 100 feet. Hedlund added that 113 of the corridor would be filled in. Schlampp asked if the area being filled was considered a wetland. Franzen replied that it was not clearly stated if this area was a wetland. Franzen added that there was concern about the fill and how much affect it would have on Purgatory Creek. Franzen stated that there could be a different grading plan which he had considered after speaking with Fielder regarding her concerns. He had not had time to discuss any alternatives with the proponent prior to this meeting. Franzen said there was a possibility with the shifting of some lot lines and the moving of some building pads that the plan could be improved and trees could be saved. Wissner stated that she would like to see a revised plan if it could be improved. Franzen replied that because a certain number of lots had been approved originally the proponent and Staff had tried to keep close to this figure. Franzen noted that reforestation was not the same as tree replacement. Franzen added that reforestation was to recreate what had previously existed. Schlampp asked if building was allowed in a 100 year flood plain area. Franzen replied that you can fill with a flood plain area. He added that the Watershed District allowed filling if the water flow was not affected. Schlampp questioned what would happen to the people in the homes constructed in this flood plain area. Hedlund replied that he would request elevations be verified with Barr Engineering. Schlampp replied that he did not believe the road elevation had changed. Mary Ann Fielder, 11975 Runnel Circle, stated that he would like to see the trees saved in the creek tributary area. Fielder was concerned about Lots 1, 2, and 3 which would be backing out of the drive onto the road. He believed this was a safety issue. Cynthia Thiese, 11758 Tanglewood Drive, asked what would happen with the natural drainage if the hill was taken down. Hedlund replied that the watershed would be limited to the backyards of the new homes. He added that the amount of watershed should be less than before because the backyards from the new and the existing would be close to the same level. Thiese asked 4 what trees would be lost. Hedlund replied a cluster of boxelder would be removed. Hedlund added that fill would be added into the draw area. Dave Fischer, 11965 Runnel Circle, asked if the 12% tree loss was only significant trees or trees in general. Franzen replied that significant trees were 12" in diameter or better. He added that a detailed tree inventory had been done and the majority of the large trees were in the area close to Tanglewood Drive. Fischer encouraged Staff to investigate further the flood history of this area. Fischer questioned the judgement of putting 20 feet of fill in an area. Fischer asked if any covenants would be established. Schwieters replied that there would be an architectural control committee and a homeowners association. Fischer stated that he would like to keep as many trees as possible for a noise and wind barrier. Ziesman asked if the hill would be taken down 15 feet. Franzen replied that the lowest elevation would be 4 feet higher than the lowest level. Ziesman asked that the elevations be verified because there was a swale which ran from the south to the north. He added that a swale can only handle so much water and, therefore, you need to either widen the swale or install a storm water sewer system. Franzen stated that the proponent would be required to match grade at property lines. Ziesman stated that he would like to see the swale at the lot boundary. Hedlund replied that he would look at the swale issues after the Preliminary Plat was approved. Clinton stated that the plan needed modification. He added that the plan is workable but needs to have more work on specific details. iWissner stated that Lots 1 and 2 needed to be looked at further. Wissner was concerned about the amount of fill being used. Schlampp also believed that Lots 1 and 2 needed to be addressed. Schlampp believed in N.U.R.P. ponds and believed that one should be required even though it was not part of the PUD approved earlier. Schlampp believed that it was basically a good plan. Kardell concurred that the flood history of the for Lots 1 and 2 needed to be addressed. Kardell questioned the straightening out of the tributary creek and its affect on the water flow. She also questioned how the plan could be revised to place the trail so that the current vegetation would not be extensively disturbed. Kardell was concerned about the 2 driveways with direct access to Homeward Hills Road but, believed that they would be acceptable if the turn-arounds were provided. Kardell suggested that handicap accessibility to the park be provided. Wissner believed that the revised plan should come back to the Planning Commission. Hedlund asked if it would be acceptable to approve Phase I and table Phase H for the revisions. Franzen believed that the residents would like to feel comfortable with the resolutions. 5 Schlampp believed that there wasn't anything in the plan which could not be resolved and recommended approving the plan with the request to resolve the issues before City Council review. Wissner stated that she would be more comfortable if the final plan returned to the Planning Commission at the next meeting to show the corrections made to the plan.

NEW BUSINESS Schlampp asked if it would be possible to get the plans the Friday before the meeting. Franzen replied plans that Staff are working from could be sent out prior to the Friday before the meeting; however, changes are often made at the last minute which would not be reflected on these plans. Schlampp stated that it would have been nice to have had a preliminary statement from the Watershed District regarding this plan. Schlampp added that he had spoken with Chanhassen and the Watershed District approves plan before the Planning Commission. Franzen replied that it could be possible to get a preliminary response. IX.
