Wawona and Vicente Streets Stormwater and Water Main Replacement
Overview
This project will install a new sewer pipe under Vicente Street, from Wawona Street to 34th Avenue. The project will also replace the aging water transmission and distribution mains on Wawona Street, 15th Avenue, and on Vicente Street west of 19th Avenue.

Project Background
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.

What to Expect During Construction
February 2023 Construction Update: Wawona and Vicente Street Stormwater and Water Main Replacement (subject to change)
Construction activities continue to progress at several locations along our project alignment as part of the Wawona and Vicente Street Stormwater and Water Main Replacement project.
Water Work at Vicente and 34th to 20th Ave
- Construction activities are ongoing along Vicente Street, spanning from 34th to 20th Avenues
- The installation of a 36-inch water transmission pipe between 25th to 19th Avenues along Vicente Street is underway and will take place for several months.
- Paving activities
- Crews are currently paving the stretch of Vicente Street from 34th to 20th Avenue
- Paving work east of 26th Avenue along Vicente Street is planned to occur in the spring, after the completion of water transmission installation work
Sewer Work at 14th & 15th Avenues and Wawona & Vicente Streets:
- Sewer drainage inlet installation continues to take place, and this work will begin on 14th Avenue and Vicente Street in early March. Approximately 4 feet of walkway on the sidewalk around the work will be available for pedestrian use, however they may be instances when crews will need to temporarily close the sidewalk during work hours and create a detour to the opposite sidewalk.
- Crews will also be installing 18-inch culverts concurrently with the drainage inlet work. Construction staging will occur along some nearby side streets in the immediate vicinity.
- Vibration monitoring is taking place in order to capture vibration data associated with construction. Monitoring is taking place in two locations: 14th & Wawona St. and 15th & Wawona St.
Get Rain Ready
- Rain is anticipated to occur this week and next week. Crews are prioritizing public safety and are working hard to prevent flooding and ensure that catch basins are cleared prior to the start of rain. Visit sfpuc.org/rain-ready to find out the steps you can take to get rain ready: apply for a Floodwater Grant (to get reimbursed up to $100k for implementing projects on your property to minimize flood damage), purchase flood insurance, inspect and clean your sewer lateral (sewer 'pipe' from your building to the city main sewer) to prevent backups or service interruptions.
We thank you for your patience as we complete these vital sewer system upgrades. For questions or comments, please email us at ssip@sfwater.org or leave a message at (415) 554-3233.
