Feasibility Report <br />2024 / 2025 Street Reconstruction and Municipal Sewer and Water Extension Project Colonial Woods City of Lino Lakes, MN WSB Project No. 023620-000 Page 5 4. Proposed Improvements 4.1 Streets The City will reconstruct the roadway back to the existing width of 28 feet (back of curb to back of curb) <br />and install concrete curb and gutter. Once curb and gutter is installed the roadway will seem narrower, <br />which will provide a level of traffic calming. The road section will consist of 4 ½ inches of bituminous on <br />top of 8 inches of class 5 aggregate base. The subgrade will be evaluated through the design process. <br />The City may incorporate reclamation into the project. Surmountable curb and gutter is proposed for the <br />entire Colonial Woods neighborhood, and will be lowered at the driveways. A proposed typical section <br />can be found in Appendix A. 4.2 Drainage The City has completed a preliminary stormwater management design that will replace and expand the <br />existing drainage systems. The design is in conformance with the City’s Stormwater Management <br />Ordinance and Rice Creek Watershed District (RCWD) Rules. The area planned for a new stormwater <br />management facility is within the 62nd Street right of way as it extends undeveloped to the east. The City <br />will be required to obtain a permit from Rice Creek Watershed District and the Minnesota Pollution Control <br />Agency (MPCA). The preliminary storm sewer design is proposed to consist of typically 12 inch to 18 inch diameter <br />Reinforced Concrete Pipe (RCP). At the time of this report, the storm system is planned to convey water <br />to the pond on the easterly end of 62nd Street and outlet to the easterly wetland. The preliminary storm <br />pipe locations and pond outline can be seen in Appendix A . 4.3 Utilities 4.3.1 Sanitary Sewer An 8-inch diameter PVC sanitary sewer will be extended east along 62nd Street to Red Maple <br />Lane. The sanitary sewer along 62nd Street is trunk sanitary sewer and will serve additional <br />properties in the future. An 8-inch diameter PVC sanitary sewer will be extended north along Red Maple Lane and extend <br />around Red Maple Lane in both the east and west directions to serve the Colonial Woods <br />neighborhood, as shown in Appendix A . Four-inch diameter PVC services would be extended <br />from the 8-inch PVC mainline sewer to the property lines. 4.3.2 Water Service Twelve-inch diameter DIP watermain will be extended east along 62nd Street to Red Maple Lane. <br />The watermain along 62nd Street is trunk watermain and will serve additional properties in the <br />future. An 8-inch diameter DIP municipal water will be extended north along Red Maple Lane and loop <br />around Red Maple Lane in both the east and west directions to serve the Colonial Woods <br />neighborhood, as shown in Appendix A. The City will loop the system to an existing 8 inch stub <br />that extends down from Fox Circle. Fire hydrants will be installed per City specifications. One inch <br />diameter copper services would be extended to the property lines. DRAF <br />T <br />234
