Dear Jeanne, ,f _ __ __ ____ This letter summarizes a meeting held on June 10, 1996 at 2800 Countryside Drive West.,'Besides you and I, the following people were present at the meeting: �-- - Tony Eiden Owner&Building Contractor Russ Olson Grading Contractor Greg and Jewel Vitas Homeowners The discussion revolved around both surface and sub-surface drainage problems encountered during the past year at the above address,described as Lot 1,Block 2, Old Crystal Bay Road Addition. Surface Drainage: The homeowners explained how the low area west of their home drains very slowly and has standing water for several hours after an average rainfall event. They were not informed that this area was a dedicated wetland which was created as mitigation for wetland loss on the project. The selling agent or owner should make it very clear to prospective homeowners where this and all other dedicated wetlands are located. It was noted that the grades in this area were very flat. The drainage from this area collects in a culvert near Old Crystal Bay Road and drains south to the sedimentation pond for the entire development. Inspection of the drainage ditch showed that minor corrections are needed to insure posit:ve drair�ag�. .y quick check of the road elevation showed that it was nearly two feet lower than the lowest window on the home which is more than adequate to prevent flooding. A drainage swale has been constructed along the east lot line as previously recommended. This swale is very shallow and may need additional grading to insure positive drainage south to Countryside Drive. The adjacent lot to the east of Lot 1 has been completely graded with no provisions inplace for erosion control. Adequate erosion control measures should be installed immediately. A fair amount of sediment has already washed from this site onto Lot 1. This erosion creates a potential for plugging culverts and filling ditches downstream. The building contractor should be required to clean the downstream culverts and ditches which have been impacted due to the erosion. The original developer maintained adequate erosion control throughout the period of installation of road and drainage improvements. The new owner or building contractor has not maintained erosion control throughout the phase of residential home construction. The homeowners are concerned about runoff from Watertown Road which flows across their property. We 2335 West Highway 3G ■ St. P�ul, MN 55113-3898 ■ G12-G3G-4G00
