LAKE ELMO CITY COUNCIL MINUTES AUGUST 15, 1989 PAGE 3 ( C. Preliminary Plat, Packard, Park, 3rd Addition Bruce Folz presented a preliminary plat for Packard Park 3rd Addition which is located east of Lake Elmo Avenue and west of Packard Park 2nd Addition. The Subdivision consists of 25.4 acres and is properly zoned R-1 for the proposed 13 lots which all meet the 1.5 acre minimum lot size. All of the lots have at least one acre of land suitable for septic system purposes and will have land sufficient for two separate drainfield sites. The Lakeshore land area between Lake Elmo Avenue and the lake will be split into four outlets and these outlets will be the extension of the existing proposed lot lines across the road going to the lake. Therefore, each person owning a lot there would own the lakeshore in front of their house. Folz explained the County requested the right-of-way be dedicated as 100' width so the developer will dedicate 17' of additional right-of-way on the westerly side to the County for highway purposes. The Council received Larry Bohrer's reports, dated August 4, 1989 and August 14, 1989, and letters from the VBWD and Washington County. Karen Chandler, VBWD, stated in her letter, August 2, 1989, that the immediately tributary area of Eden Park Pond and Durand's Pond alone will not cause the high water levels. Hence, the effect of the Packard Park development upon the 100-year flood elevation is expected to be minimal. The Council also received concerns and questions regarding this continued development, which were handed out at the August 14, 1989 PZ meeting by Debra Wilfong, 2229 Legion Avenue, and pictures (dated 7-9-89) showing erosion of the holding pond and sedimentation in the outlet pipe. Larry Bohrer explained that the improvements for the 3rd Addition would provide a stormsewer system of catch basins and pipes in 24th Street from 24th Street Court directly into the pond. "Much discussion has centered on whether this subdivision contributes to the problem on Durand's property and the Eden Park Subdivision and the performance of the pond, Bohrer stated, and it is true the pond does not perculate as other ponds we have seen in the City. However, he does not find a code requirement that requires the pond to meet a certain perculation rate". Bohrer indicated the pond is sized according to the adopted 1988 Stormwater Control Ordinance and development of this subdivision would have a minimal effect. In regard to the PZ's recommendation of routing the water from the pond into Lake Elmo, Bohrer had two concerns: (1) transferring water from one sub -watershed into another; and (2) would this controlled drainage into Lake Elmo detrimentally effect the water quality of Lake Elmo. The Council made the following motion in order to review the information that was presented. M/S/ Hunt/Williams - to postpone consideration of Packard Park 3rd Addition until the September 5th City Council meeting. Concerns were expressed relative to the effectiveness of the drainage system and, in particular, the holding pond on the site due to the lack of permeability and seepage from the pond. In an effort to eliminate drainage concerns presented, the Council discussed useage of a storm drainage pipe
