CONSENT ITEM - 6F MEMORANDUM DATE: April 10, 2017 TO: Honorable Mayor and City Council Members William S. Joynes, Sr., City Administrator FROM: Sue Polka, Public Works Director/City Engineer SUBJECT: Rice Creek Watershed District Maintenance Agreement for the 2015 Pavement Management Program Background/Discussion The Rice Creek Watershed District (RCWD) requires the installation and maintenance of new storm water management facilities according to the district rules for city public works’ projects, including street and utility improvement projects. Storm water management facilities, such as infiltration basins and rain gardens, are constructed within the right- of- way or in trail easements as needed as part of the City’s PMP projects. Seven facilities will be constructed as a part of the 2015 PMP. One of the permit requirements is to enter into a Maintenance Agreement covering the maintenance of the new storm water management facilities. Maintenance of these facilities is required by our Minnesota Pollution Control Agency Storm Water Pollution Prevention Permit (SWPPP). It is also consistent with our Public Works policies to adequately maintain infrastructure. A copy of the agreement is attached. Seven rain gardens were constructed as a part of the 2015 PMP on City rights of way or within existing easements. One garden is located on Grant Road, four on Noble Road, and two along trails within the project area as shown on Exhibits A and A2 of the agreement. Financial Implications The Public Works Department is committed to maintaining new facilities when they are installed. This agreement does not increase our level of maintenance over what we would have done without the agreement. Five of the gardens are located in residential yards and will be maintained by the property owners. Additional raingardens were constructed with the project but are not covered by this agreement and also will be maintained by the property owners.
