<br /> <br />2017 STREET AND UTILITY IMPROVEMENT PROJECT <br />FEASIBILITY REPORT <br />CITY OF ST. ANTHONY VILLAGE <br />WSB PROJECT NO. 2170-34 PAGE 6 <br />4. PROPOSED IMPROVEMENTS <br /> <br />4.1 Sanitary Sewer <br /> <br />The existing 9-inch VCP will be reconstructed with 8-inch polyvinychlorde (PVC) pipe, <br />including the replacement of sanitary sewer services. All services are proposed to be <br />replaced with 6-inch PVC service pipe from the sewer main to the right-of-way. <br />Replacing aging trunk utility facilities at the same time as the road construction is a <br />proactive means by which to mitigate future maintenance costs. <br /> <br />The proposed sanitary sewer improvements are shown on Figure 4 in Appendix A. <br /> <br />4.2 Water Main <br /> <br />Existing 6-inch CIP is proposed to be replaced with 8-inch DIP, including the <br />replacement of water services up to and including the curb stop. Services will be replaced <br />with 1-inch copper service pipe and curb stops brought to the right-of-way. All existing <br />water main in the project area will be equipped with new valves and hydrants as <br />necessary for proper operation and fire protection. Replacement of existing services will <br />alleviate head loss and increase water pressure to properties by providing a clean service <br />pipe. <br /> <br />The proposed water system improvements are shown on Figure 5 in Appendix A. <br /> <br />4.3 Storm Sewer <br /> <br />Reconstruction of the road provides the opportunity to improve drainage in the area with <br />the installation of additional storm sewer facilities. The existing storm sewer system will <br />be improved with the addition of catch basins along the roadway to better accommodate <br />area drainage and the extension of new storm sewer where facilities do not currently <br />exist. <br /> <br />The proposed storm sewer improvements are shown on Figure 6 in Appendix A. <br /> <br />4.4 Street <br /> <br />Reconstruction of the existing street is intended to improve the design strength of the <br />pavement system and provide a street surface with an extended life for the City of St. <br />Anthony Village. Penrod Lane, Skycroft Drive, Maplewood Drive, and Chelmsford <br />Road are proposed to be replaced at the current width of 30 feet from back-of-curb to <br />back-of-curb, which allows for two 12-foot driving lanes and 2-foot reaction areas on <br />each side of the street. <br /> <br /> <br />24
