Page 2 of 5 <br /> <br />Storm Drainage and Storm Water Quality Improvements: <br />Storm Drainage improvements involve increasing the storm collection capacity of the <br />system already inplace in the neighborhood. Storm Water Quality Improvements, as <br />required by Rice Creek Watershed District, are dependent on the type of work proposed <br />in the permit. City staff has met with watershed district staff and established that street <br />reclamation is not an activity that requires storm water treatment and falls under the <br />definition of rehabilitation. The amount of storm water treatment required by Rice Creek <br />Watershed will be dependent on the level of improvement to the roadway. At this point <br />based on our conversations with the watershed we estimated the following amount of <br />treatment to be required for each option: <br /> <br />Alternative 1 – Reconstruction – 16,503 Cubic Feet <br />Alternative 2 – Reclamation – 8,215 Cubic Feet <br /> <br />The City created an excess of storm water treatment along with the Valentine Park <br />Improvement and will receive credit to be applied to this project which will in turn <br />reduce the amount needed to be constructed at this time. <br /> <br />Water System Improvements: <br />Based on review of watermain break history the improvements to the water system <br />include replacement of the watermain on the following streets: <br /> <br />Venus Avenue, Dellview Avenue to Rolling Hills Road <br />Crystal Avenue, Fairview Avenue to Lake Valentine Road <br />Glenview Court, Glenview Avenue to Cul-de-sac <br />Glenview Avenue, Crystal Avenue to Dellview Avenue <br />Fairview Avenue, Gramsie Road to Venus Avenue <br />Gramsie Road, Rolling Hills Road to Dellview Avenue <br /> <br />Replacement as suggested will cover the areas hit hardest with breaks and cover 90% of <br />the areas where problems have been experienced. Additionally all hydrants and gate <br />valves in the neighborhood will be replaced. <br /> <br />Sanitary Sewer System Improvements: <br />The sanitary sewer improvements associated with the project include replacement of the <br />manhole frames and covers to match the new street grade. Future sewer lining projects <br />can line the clay sewer mains as funding becomes available. <br /> <br />Financial Implications <br />The estimated total project cost for the improvements is $3,963,770 which includes all <br />overhead costs.
