Specifications include, but are not limited to:As part of its Sewer System Improvements Program (SSIP), the SFPUC is proposing the Project to improve the areas sewer system performance during wet weather. The neighborhood surrounding the intersection of Kansas and Marin Streets has historically been subject to flooding during moderate to heavy storms. The City has identified and analyzed various solutions to the flooding challenges and completed an Alternatives Analysis Report (AAR) and a Conceptual Engineering Report (CER) to meet the Projects needs. This proposed Project will provide an auxiliary sewer (an 8-foot diameter tunnel, approximately 900 feet long) that provides additional conveyance capacity and serves as a connection between an existing 12.5-foot x 6.5-foot reinforced concrete box sewer under Marin Street and another 20-foot x 30-foot reinforced concrete box sewer (the Contract C Box) inside the SFPUCs property, Lot 31. The proposed auxiliary sewer would allow wet weather flows to enter the Contract C Box earlier, thereby, lowering the hydraulic grade line (HGL) of the Marin Street sewer.
