The SWMP indicates that water quantity may be a problem downstream from this site and <br />recommends restricting this outlet to 27 inches in diameter. Reducing the size of the wetland <br />outlet pipe wili reduce the rate of storm water downstream but will inaease the higli water <br />level (HWL) of the wetland to an devation of approximately 966. We can review the <br />wetland outlet sizing once a drainage area map, storm sewer and ponding calculations are <br />provided. These calculations should be based on the total drainage area reaching the wetland. <br />Final plans should be submitted to the Minnehaha Creek Watershed District for thdr review. <br />4. Easements: A 10-foot trail easement should be dedicated along the west edge of the <br />property. Drainage and utility easements should be provided 5 feet wide along all interior lot <br />lines and 10 feet wide along the roadway right-of -ways. Drainage easements should be <br />provided across all wetlands, drainage ways and pond areas. <br />5. Financial Guarantee: When the plans have been completed we will prq)are an estimate of <br />the total cost for the site improvements to determine the amount of the financial guarantee <br />required. <br />Please contaa me at 651-604-4863 if you have any questions regarding this matter. <br />Yours very truly, <br />BONESTROO, ROSENE, ANDERLIK & ASSOCIATES, INC. <br />Tom Kdlogg <br />Cc: Greg Gappa, City of Orono
