224 this system. A reduction in the peak flow from the commercial properties located in the <br />225 subwatershed will alleviate the demand an the 35W truza.k sewer. <br />226 <br />227 G. Area 7: Como Sub 7W Gottfried Pit <br />228 In 2003, the City of Roseville cooperated with Capitol Region Watershed District <br />229 (CRWD), Falcon Heights, the City of St. Paul, azad Ramsey County an a study of down <br />230 stream flooding and water duality issues for the northwestern watershed area to Coma <br />231 Lake. All of these entities contribute storm. water Flow to Como Lake. This study <br />232 identified improvements that would be made to mitigate the ongoing stonxz water issues <br />233 in this area. The study also assigned proportional cost shares to each entity based on <br />234 contributory flow with CRWD agreeing to contribute funding for a portion of the <br />235 improvements. They served as the lead agency on this study and for the subsequent <br />236 improvements to occur on the Cozno Golf Course and additional storage at Arlington and <br />237 Hamline Avenues. <br />238 <br />239 Roseville drains 315 acres into Cozno Lake via Gottfried Pit near Fez-nwood Street and <br />240 Larpenteur Avenue. The work completed as a part of the agreement does not completely <br />241 address the drainage concerns detailed in the report. <br />242 <br />243 Action to Date: <br />244 This subwatershed was added as a problem area in 2006. In an effort to address some of <br />245 the flooding concerns in this problem area, staff will continue to require redevelopment <br />246 projects to reduce the volume of water that is sent to this system. A reduction in the peak <br />247 flow from the commercial properties located in the subwatershed will alleviate the <br />248 demand on the Gottfried Pit. <br />249 <br />250 Recommended 200$ action. <br />251 With the proposed redevelopment of Rainbow Foods at Larpenteur and Femwood, City <br />252 Staff would like to explore the possibility of constructing additional storm water storage <br />253 for this watershed underneath the newly reconstructed parking lot. This would be <br />254 accomplished through the installation of an underground chamber system owned and <br />255 maintained by the City. We have met with the developer and are working with CRWD <br />256 on preliminary engineering estimates for this system. Once we have a better idea of the <br />257 scope of this proposal, we will bring the project to the City Council for review, <br />258 <br />259 H. Area S: Center Street <br />260 For years we have been working on finding a resolution for street flooding at the <br />261 intersection of Center Street and Rice Street. This is the result of the sediment that has <br />262 accumulated in tl~e ditch located on the east side of Rice Street in the City of Maplewood. <br />263 Center Street drains under Rice Street via a culvert, the sediment in the receiving ditch <br />264 causes Roseville's side of Rice Street to flood. As a result, any solution for this street <br />265 flooding requires cooperation from Maplewood. Since it is a cross jurisdictional issue <br />266 that involves the Trout Brnok Interceptor, CRWD needs to be involved. The tln•ee <br />267 jurisdictions have agreed that CRWD will study the problem and recommend a solution. <br />268 <br />City of Roseville <br />24Q7 Storm Water Annual Report page 7 of 15 <br />
