Department Approval �-. l�'�, Jy REQUEST FOR COUNCIL ACTION Date: 6/29/09 Item No.: 7 . h City Manager Approval Item Description: Approve an Agreement with the City of Lauderdale for Connection to Sanitary Sewer System BACKGROUND Staff has previously discussed the mill and overlay and safety improvements project being undertaken by the Minnesota Department of Transportation on Trunk Highway 280 this year. This project has an impact on the city's sanitary sewer lift station that serves the Paper Calmenson site. The operation of the highway after this project will cause a safety concern for maintenance of the lift station which currently is off the shoulder of the roadway. We have had considerable discussion with MnDot regarding relocation of this lift station and they have agreed to pay for a portion of the relocation costs. We have an agreement drafted by MnDot that has been reviewed by the City Attorney for the participation in relocating or eliminating this station. Staff is requesting action on this agreement separately. � The City of Roseville studied the feasibility of relocating or eliminating this lift station in 2004. The � preferred option identified in that study was eliminating the lift station by constructing a gravity line to � the City of Lauderdale to allow conveyance of the wastewater to the Metropolitan Council's trunk � system via a relatively new line in Lauderdale's system. This was the lowest cost to construct alternative � identified and has the least long term maintenance costs and operational potential problems. Replacing � this lift station with another mechanical station and new gravity and force mains would cost � significantly more than this alternative. Lauderdale has adequate excess capacity in their line to � accommodate redevelopment of the PaperCal site to a higher use. We have discussed this connection � with Lauderdale staff and their City Council and have had our City Attorney draft an agreement for this � connection (Attachment A). Per the agreement Roseville will pay Lauderdale a connection charge for � the needed capacity. This was calculated as a percentage of the construction cost of their line based on � the flow percentage we need to accommodate future redevelopment for this site. The connection charge , is a one time cost of $87,500. Per the agreement Roseville will share in future maintenance of the , Lauderdale line. , The lift station we are eliminating has been in place for nearly 50 years and is in need of replacement. � We have not proposed reconstruction of this station previously in anticipation of the need to relocate for � safety reasons and the current lack of capacity for future redevelopment of the area of service. � POLICY OBJECTIVE , The City of Roseville has constructed sanitary sewer facilities to serve all properties in the city. The city � maintains these facilities to ensure reliable service that minimizes the potential for disruption of service and potential for property damage. Page 1 of 2
