Page 2 of 5 <br /> <br />also includes addition of concrete curb and gutter throughout the entire neighborhood. <br />The second option, Reclamation, involves pulverizing the existing bituminous surface <br />and recycling that material to be used as an aggregate base. This option is less expensive <br />and has less impact to the surroundings. The existing street has bituminous curb in some <br />locations to direct drainage or support steep boulevard grades. Bituminous curb would <br />not be possible to replace in the reclamation option due to the grades and the need to <br />build the road surface up. <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 staff estimates the following amount of <br />treatment to be required for each option: <br /> <br />Alternative 1 – Reconstruction – 7,778 Cubic Feet <br />Alternative 2 – Reclamation – 5,715 Cubic Feet <br /> <br /> <br />Water System Improvements: <br />Watermain in this neighborhood shows no history of breaks and therefore the only water <br />improvements involve replacement of all hydrants and gate valves in the neighborhood. <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. The sanitary sewer in this <br />neighborhood was lined in 2011. <br /> <br />Financial Implications <br />The estimated total project cost for the improvements is $1,642,370 which includes all <br />overhead costs.
