REQUEST FOR COUNCIL ACTION Date: 08/12/13 Item No.:7.e Department Approval City Manager Approval Item Description: Approve Maintenance Agreement for Stormwater Management Facilities between Rice Creek Watershed District and the City of Roseville for M-12-13 Twin Lakes Area Street Improvements Project Page 1 of 2 B ACKGROUND 1 The 2013 Twin Lakes Area Street Improvement Project consists of the public street improvements 2 required for the construction of the Wal-Mart in the Twin Lakes Redevelopment Area. This project 3 includes the following work: 4 x Right turn lane on County Road C into the Wal-Mart Parcel; 5 x Eastbound left turn lane and median improvements into the Wal-Mart Parcel and westbound left 6 turn lane on County Road C to southbound Cleveland Avenue; 7 x Right turn lane on Twin Lakes Parkway into the Wal-Mart Parcel; 8 x Right turn lane from westbound County Road C to northbound Cleveland; and 9 x Twin Lakes Parkway Roundabout Improvements. 10 This project modifies the existing storm water management facilities that were constructed as a part of 11 the 2009 Twin Lakes Infrastructure project. As a result it is necessary to modify the original agreement 12 for these facilities. The modifications include the removal of an existing infiltration swale and the 13 construction of an infiltration basin, as well as new catch basins and pipes. All of this is being 14 constructed within the right- of- way as part of the project. These facilities are necessary to meet Rice 15 Creek Watershed District’s storm water treatment requirements and the City’s Green Infrastructure 16 goals.17 The District requires the installation and maintenance of new storm water management facilities 18 according to the district rules for city public works’ projects, including street reconstruction projects.19 One of the permit requirements is to enter into a Maintenance Agreement covering the maintenance of 20 the new storm water management facilities. 21 P OLICY O BJECTIVE 22 This agreement will cover the storm water management facilities constructed in association with this 23 project. Maintenance of storm water facilities is required by our Minnesota Pollution Control Agency 24 Storm Water Pollution Prevention Permit (SWPPP). It is also consistent with our Public Works Policies 25 to adequately maintain infrastructure. 26 F INANCIAL I MPACTS 27 The Public Works Department is committed to maintaining storm water facilities when they are 28 installed. This agreement does not increase our level of maintenance over what we would have done 29 without the agreement. 30
