Folsom Area Stormwater Improvement Project
Overview
The Folsom Area Stormwater Improvement Project is a part of the San Francisco Public Utilities Commission's (SFPUC) flood resilience efforts under the Sewer System Improvement Program (SSIP). The low-lying Inner Mission neighborhood surrounding 17th, 18th and Folsom Streets has been historically subject to flooding during moderate to heavy storms. The Folsom Area Stormwater Improvement Project will increase collection system capacity and reduce the risk of flooding by constructing and upsizing sewer pipes and boxes, as well as constructing a new stormwater tunnel.
NOTE: Even after this work is complete, this area will still be at risk of flooding during heavy rains. Additional resources are available at sfpuc.org/rain-ready.

Project Background
The project consists of two separate components:
The upstream components of the project consist of constructing and upsizing approximately 8,000 linear feet of sewer pipes and sewer boxes in various locations in the neighborhood.
The tunnel component of the project consists of constructing a new 4,000 linear foot stormwater tunnel from approximately the intersection of Alameda Street and Florida Street to the intersection of 7th Street and Berry Street.
