Streets and Alleys CSAH 23 is an "A" minor arterial reliever road. 77th Street and Market Place Drive are local roads. The main entrance to the site is at CSAH 23 and Market Place Drive which is a signalized intersection capable of handling additional traffic to the site. A secondary driveway access is provided off of 77th Street; however, the right in -right only onto 77th Street from CSAH 23 will limit traffic use on 77th Street. The existing road system is capable of handling traffic generated from the development. The City, WSB Traffic Engineer, Anoka County and Police Department analyzed the need for a right turn lane on CSAH 23/Lake Drive at 77th Street. It was determined a turn lane was not warranted. The driveway access onto 77th Street shall be egress only and signed "Exit Only" to eliminate the need for assisted -living traffic to turn right onto 77th Street from CSAH 23. Traffic will continue to have full access at CSAH 23 and Market Place Drive. Easements A drainage and utility easement of 10 feet and 25 feet wide are provided along the interior perimeter of the lot. Storm Water Management and Erosion and Sediment Control Storm water quality requirements will be achieved using a surface pond providing infiltration. The "A" soils are conducive to this type of stormwater management. This pond will infiltrate the required water quality volume (2.5 inches of rainfall over the drainage area) and route storms exceeding this runoff volume through a control structure in the pond. A control elevation will be established at the quality volume for discharges above this amount of runoff. For informative purposes the 1 -year storm precipitation amount is less than the required quality runoff, thus no discharge from the pond is anticipated from this storm event. Utilities Utilities will connect to existing mains; water along CSAH 23, sewer to the main on 77th Street, and stormwater to an existing catch basin on CSAH 23. Electric and telephone will connect on an existing pole on 77th Street and gas will connect to an existing main running just south of the property. The parking lot will be graded so as to drain to a series of catch basins. The roof runoff will be collected and conveyed underground to the proposed stormwater pond on the west side of the property. Public Land Dedication The City will require cash in lieu of land dedication. The assisted -living facility will be considered commercial for the purpose of calculation park dedication fees. 3
