Roseville Public Works, Environment and <br />Transportation Commission <br />Agenda Item <br />Date: November 23, 2010 Item No: 5 <br />Item Description: William Street Stormwater Partnership Project Presentation <br />Background: <br />In 2009, the Capitol Region Watershed District (CRWD) completed the McCarrons <br />Subwatershed 4 Study. This study identified retrofit/ maintenance opportunities within the <br />drainage area to the Northeast of Lake McCarrons that would reduce the phosphorus loading and <br />improve water quality. CRWD was approached by Ramsey Conservation District (RCD) <br />regarding grant funds available in 2010 for construction projects in Ramsey County. <br />William Street Pond was one of the locations identified in this study as a potential retrofit <br />project. This pond is located at the southeast corner of William and Elmer Street. The main goal <br />of the project is to increase the water quality treatment efficiency. This will be accomplished by: <br />restoring the pond to its original constructed depth, <br />repairing the erosion at the inlet, <br />installing a pretreatment manhole along Elmer Ave <br />retrofitting the pond outlet with a filter bench, to increase the pond storage, and treatment <br />efficiency. <br />This project is currently scheduled for construction this winter. The engineer's estimate for this <br />project is $65,875. This cost is proposed to be shared by CRWD ($15,875), RCD ($25,000) and <br />the City of Roseville ($25,000). CRWD has a contract for project engineering with Wenck and <br />Associates. <br />Staff has invited the neighborhood to the commission meeting so that they may have an <br />opportunity to learn about what is proposed for this project. <br />Recommended Action: <br />Discuss the proposed project <br />Attachments: <br />A.
