Wawona and Vicente Streets Stormwater and Water Main Replacement

The intersection of 15th and Wawona does not meet the citywide design standards for stormwater management and has been susceptible to flooding associated with moderate and heavy storms. The Wawona and Vicente Streets Stormwater and Water Main Replacement project will bring this area up to the citywide design standard for stormwater management and reduce the risk of flooding in the area of 15th Avenue and Wawona Street.

It is important to note that even after project completion, this area will still be at risk of flooding during heavy rains. For more information on stormwater management, visit sfwater.org/rainreadysf. To minimize disruption from construction and staging to the surrounding community, the SFPUC is coordinating with other large projects in the area including the L-Taraval Improvement Project and the 19th Avenue Improvement Project.

Project Benefits

• Reduce the risk of flooding by diverting some of the stormwater flow to a new large sewer pipe to be installed under Vicente Street, from Wawona Street to 34th Avenue
• Increase the ability to capture and divert street runoff with new stormwater inlets around 15th Avenue and Wawona Street intersection
• Upgrade the aging water transmission and distribution mains along Vicente and Wawona streets

About the SSIP

The San Francisco Public Utilities Commission (SFPUC) recently launched the Sewer System Improvement Program (SSIP), a 20-year citywide investment to upgrade our aging sewer system and provide a more reliable, sustainable, and seismically safe system now and for future generations. The SSIP includes a series of facility upgrades at the Southeast Treatment Plant (SEP) located in the Bayview neighborhood of San Francisco.
