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 Highway 23, sewer to the main on 77t' Street, and stormwater to an existing catch basin on Highway 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. Park Dedication FeeE;$4r,133 !1.9!0acres x $2,175 per acre = Tree Preservation The preliminary plat identifies 18 trees on site. The demolition plan indicates the removal of approximately 4 trees and undergrowth shrubs within the non -ESA Basic Use Area. No tree mitigation is required.
