PROPOSED UTILITY IMPROVEMENTS <br /> Existing manholes, fire hydrants, gate valves, and other similar structures will be adjusted and <br /> repaired as necessary as part of this project. The cost of underground utility improvements will <br /> be excluded from the assessable portion of the project and financed by the appropriate utility <br /> funds. <br /> City staff will coordinate with private utility owners such as gas, electric, cable television, and <br /> telephone throughout the construction project. <br /> Water System <br /> Due to the history of watermain breaks within the project area, the recommended water system <br /> improvements include abandoning and replacing the existing watermain with a PVC pipe system <br /> on Edgewater Avenue and Ridgewood Road from Glenhill Road to the cul-de-sac.. As noted by <br /> the Public Works staff, the watermain breaks have been as a result of pipe displacements and <br /> settlements; PVC pipe will be less conducive to these types of watermain breaks. In addition to <br /> watermain replacement noted all valves and hydrants in the neighborhood will be replaced. <br /> Sanitary Sewer System <br /> The recommended sanitary sewer system improvements are relatively minor and include <br /> maintenance on all manholes. Manhole castings will be replaced with new, standard sized <br /> castings with concealed pick holes and chimney seals to reduce the potential for inflow and <br /> infiltration. There is a need to line the sanitary sewer mains in the neighborhood. All of the pipe <br /> segments within the project have been televised and inspected. From the televised inspection, <br /> City staff will be considering including the balance of the unlined sewers in a future lining <br /> project. A portion of the sanitary sewer along Ridgewood Road was lined as a part of the 2011 <br /> Sanitary Sewer Lining Project. <br /> Storm Sewer Upgrades <br /> Storm sewer upgrades will require the abandonment and/or removal of the existing in-place <br /> storm sewer system. Additional storm sewer inlets throughout the neighborhood are needed to <br /> capture overland flows thereby reducing future street maintenance, improving passibility <br /> during storm events and reducing icing in the wintertime. Refer to Appendix A for a proposed <br /> layout of the neighborhood storm sewer system. If reclamation is the selected option for <br /> pavement rehabilitation the new storm sewer system would be scaled back in order to <br /> minimize disturbing the existing base. <br /> The new drainage system will also direct storm drainage to both localized and regional <br /> treatment devices to reduce pollution, decrease overall runoff volume and increase water <br /> quality within the Lake Johanna system. <br /> 7 <br />
