2009 PMP 3/5/2009 Page 2 providing a continuous flow line for stormwater runoff. This will create dips in the road, collecting water and ultimately creating pavement distresses as the water seeps through the pavement surface. Concrete curb and gutter also has a longer life span than bituminous curb. Future street maintenance and improvements will most likely consist of spot curb repairs, as opposed to complete removal and replacement. Utility Improvements Watermain No major water main repairs are proposed as a part of this project. There have been few water main breaks in the area in last 1 0 years. We have, however, included a contingency for gate valve and/or hydrant repairs if any problems are identified during construction while other project improvements are being made nearby. Sanitary Sewer No major sanitary sewer improvements are proposed. Five segments of pipe will be replaced (three on Glenarden Road~ two on Skiles Lane), where lining or other trenchless technologies cannot be applied because of sags in the pipe. Chimney seals and solid manhole covers will also be placed on all sanitary sewer manholes. Manholes with structural deficiencies will be incorporated into the proposed manhole rehabilitation project; we anticipate that it will be more cost-effective to lump these manholes into a larger specialty project rather than have a few included in this contract. Storm Sewer The existing storm sewer system will be improved and expanded throughout the neighborhood. Best management practices (BMPs), such as rain gardens, infiltration swales, and other features have been incorporated into the project in order to meet the Rice Creek Watershed District's (RCWD) water quality requirements. The design team is working with nine residents to construct BMPs in the boulevards in front of their properties. Four areas have been identified on City property for City BMPs as well: two at Lindy Park, one at Freeway Park, and one at the dead end of Skiles Lane in City right-of-way. The permit application has been submitted to RCWD. Ifrevisions to the plan are necessary for permit approval, addenda will be issued as needed prior to the bid opening. FINANCIAL IMPLICATIONS The estimated total project cost for the improvements is $1,930,769.22, including contingency, engineering and overhead fees as outlined in the Assessment policy. The City's portion of the project costs are currently budgeted from the PIR and Utility Enterprise Funds (sanitary sewer, surface water and watermain funds). A project cost summary is listed below.
