12-foot wide lanes and a 4-foot wide reaction area next to the curb and gutter. The proposed street section for this road is in accordance with City and MnDOT requirements. Based on typical soils in Elk River, the proposed pavement section consists of 8 inches of Class 5 aggregate base, 2 inches of bituminous base course, and 2 inches of bituminous wear course. The proposed street section will be verified by a geotechnical investigation. Proposed improvements also include a 6-foot wide sidewalk located on the west side of Zane Street. Estimated costs for sidewalk have been included in the street construction cost. Sanitary Sewer The proposed sanitary sewer improvements, as shown on Exhibit 5, consist of extending an 8-inch lateral sanitary sewer from the current termination point at the north end of the Mississippi Ridge Addition. The proposed sanitary sewer alignment along Zane Street would provide service to the adjacent properties, allowing for the discontinued use of the on-site sewer systems currently being used by the businesses. Stubs would be provided to the two undeveloped properties. Watermain The proposed watermain improvements, as shown as Exhibit 6, consist of extending a 10-inch trunk watermain from the current termination point at the north end of the Mississippi Ridge Addition. The watermain would be connected to the 16-inch stub under Trunk Highway 10 near the Americlnn, creating a looped system. Storm Sewer The proposed typical section for Zane Street includes barrier curb. The existing storm sewer system is adequate to handle the drainage from the new road but will need to be modified slightly to collect the runoff. The proposed storm drainage improvements are shown as Exhibit 7. Pipe material will be reinforced concrete. Inlets will be standard catch basins built into the proposed concrete curbing. FEAS-STUDY 5
