Folsom Area Stormwater Improvement Project


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. This capital project will construct new infrastructure to improve collection system capacity to manage stormwater for the level of service (LOS) storm, which has a 20% possibility of occurring in a given year. 

  • Construction Start: 2023
  • Contruction End: 2027
  • Project Phase: Design
