There are several issues that need to be addressed relative to engineering matters and included with the plan. 1. Utilities: The proposed sanitary sewer design appears acceptable from an engineering standpoint. Final plans should show service locations and elevations. Part of the area to be served is outside the current MUSA boundary. 2. Streets: We usually discourage islands in cul-de-sacs. A minimum of a 45-foot radius to the face of curb and 110 feet of right-of-way should be provided if islands are used. Final plans should include a typical street section based on a geotechnical analysis of the site. The driveway for Lot 11 is shown on the shared driveway for Lots 9 and 10. The City Code allows only two units on a shared driveway. 3. Grading:The proposed grading plan appears acceptable. Due to the steep topography grading plans for individual lots should be prepared prior to issuance of building permits. Where will the driveway be located for Lot 1? There should be some discussion regarding future plans for and proposed access to Outlots A and B. 4. Drainage: Storm sewer design should include provisions for controlling runoff at the south end of the site on Wildhurst Trail. Final plans should be submitted to the Minnesota DNR and Minnehaha Creek Watershed District for their review and approval. Storm sewer and ponding and calculations should be included with the final plans. The storm sewer should be designed to minimize velocities at the pond inlet. 5. Easements: Drainage easements should be provided across all drainage ways and ponding areas. Easements should be provided for any existing utilities within the areas to be vacated. 6. Financial Guarantee:We have attached an estimate of the total cost for the site improvements and the amount of the required financial guarantee. Please contact me at this office if you have any questions regarding this matter.
