4.PROPOSED IMPROVEMENTS <br />4.1 STREET AND UTILITY IMPROVEMENTS <br />4.1.1 Sanitary Sewer <br />The existing 9-inch VCP will be reconstructed with 8-inch polyvinylchloride (PVC) pipe, including the <br />replacement of sanitary sewer services. All services are proposed to be replaced with 6-inch PVC <br />pipe from the sewer main to the right-of-way. Replacing aging trunk utility facilities at the same time <br />as the road construction is a proactive means by which to mitigate future maintenance costs. <br />The proposed sanitary sewer improvements are shown on Figure 4 in Appendix A. <br />In preparation for the project, individual services will be televised beyond the right-of-way to identify <br />and locate deficiencies. The results of the televising will be made available to property owners, along <br />with a copy of the televising video, and a recommendation based on the televising inspection. Costs <br />associated with these improvements would be the responsiblity of the property owner. However, the <br />City will allow property owners to have the private repairs to their sanitary sewer service added to the <br />project assessment on their property. <br />4.1.2 Water Main <br />The existing 6-inch and 8-inch watermain is proposed to be replaced with 8-inch ductile iron pipe <br />(DIP) including the replacement of water services up to and including the curb stop. Services will be <br />replaced up to the right-of-way with the appropriate 1-inch copper service pipe. All existing water <br />main in the project area will be equipped with new valves and hydrants as necessary for proper <br />operation and fire protection. Replacement of existing services will alleviate head loss and increase <br />water pressure to properties by providing a clean service pipe. <br />The proposed water system improvements is shown on Figure 5 in Appendix A. <br />4.1.3 Storm Sewer <br />Reconstruction of the road provides the opportunity to improve drainage in the area by installing <br />additional storm sewer facilities. The existing storm sewer system will be improved by the addition of <br />catch basins along the roadway to better accommodate area drainage and the extension of new <br />storm sewer where facilities do not currently exist. <br />The proposed storm sewer improvements is shown on Figure 6 in Appendix A. <br />Draintile is also proposed along the curb line to allow properties to connect their foundation drain and <br />sump pump into the storm sewer system. Redirecting this flow to the storm sewer system will help <br />minimize the treatment of unnecessary clear water that may be discharging into the sanitary sewer <br />system. <br />4.1.4 Street <br />Reconstruction of Rankin Road is intended to improve the design strength of the pavement system <br />and provide a street surface with an extended life for the City of St. Anthony Village. Rankin Road is <br />on the municipal state-aid (MSA) system and will be constructed to MnDOT design standards, which <br />allows for two 11-foot driving lanes and parking along one side of the street. Street grades are <br />proposed to match closely with existing grades to minimize construction impacts to adjacent <br />properties. <br />After the subgrade excavation is completed in the streets, a geotextile fabric will be placed to <br />separate the existing underlying soft materials from the granular materials.
