Geary Boulevard Sewer and Water Improvements Phase 2
Aging water and sewer pipelines are being replaced or rehabilitated on Geary Boulevard between 32nd Avenue and Stanyan Street. Most of this infrastructure is over 120 years old, dating back to the late-1800’s when it was installed for the early development of the Richmond District.
Sewer upgrades will improve system reliability, increase capacity, and reduce the risk of flooding and backups for residents and businesses. Water system upgrades will improve water pressure, flow and reliability for homes, businesses, and firefighting. Approximately 1.4 miles of sewer mains and 6.7 miles of water mains will be replaced or rehabilitated.
The project is split into two segments - Segment A: 32nd Avenue to 12th Avenue; Segment B: 12th Avenue to Stanyan Street.
Nightwork Alert
SFPUC crews will be making nighttime water system connections. Water service may be temporarily interrupted. If so, we will provide advanced notice.
This work is being done at night to accommodate the needs of neighborhood businesses which are affected by the temporary interruption of water service.
- Intersection of 12th Avenue and Geary Boulevard: Monday, October 20 from 8 pm to midnight
- Geary Boulevard between 23rd and 24th Avenue: Wednesday, October 22 from 9 pm to 1am

Construction Look Ahead Schedule
Below is the expected construction schedule. All work, locations, and dates are tentative and may change at any time based on the contractor’s progress.
Some work will be completed faster than others. Depending on what aspect of work is being performed, construction duration can range from one day to all week.
Temporary parking restrictions will be necessary in active work zones during construction hours. Schedule is subject to change.

Project Overview
The first phase of improvements along the Geary corridor was completed in 2021. That phase rehabilitated or replaced approximately 2.5 miles of aging sewers and replaced approximately 5.8 miles of aging water lines along Geary Boulevard from 48th to 32nd avenues and from Presidio Avenue to Kearny Street. Additional upgrades and transit improvements were also completed from Stanyan to Market streets.
The second phase of Geary Boulevard work will bring these improvements to more of the corridor between 32nd Avenue and Stanyan Street.
Work will include:
Water System Upgrades: Rehabilitate or replace water mains and connect existing service laterals. This will involve a temporary interruption of water service to connect individual property's water laterals to the new water main. Advance notice will be provided. Work may be performed at night to accommodate neighborhood businesses which are affected by the temporary interruption of water service.
Sewer System Upgrades: Rehabilitate or replace sewer main and connect existing laterals. Sewer service in the area will not be interrupted.
Transit and Safety Improvements: Work by the SFMTA, including sidewalk extensions (“bulbs”), new pedestrian medians and traffic signal work will be performed at spot locations. Learn more at SFMTA.com/Geary.
Roadway repaving: Once the entire project has been completed, final paving will be performed by SF Public Works.
We will be partnering with the SFMTA on this project. By partnering with other City departments, we can, when possible, time these crucial pipeline upgrades in coordination with other City projects. We call this our 'dig once' approach. Upgrading water and sewer pipes together with the SFMTA's planned surface level improvements minimizes disruption to the communities we serve. It also maximizes City resources by combining efforts into these large projects.

Scope of Work Per Block Maps
The process of replacing sewer and water mains involves multiple steps, so construction will not occur continuously. Crews will need to return to the same block several times to work, often with months between visits. Night and weekend work, as well as overnight road closures may be needed.
Temporary paving will be in place following the utility work. Final pavement restoration will be part of the SFMTA's surface level transit and safety improvements.
The following maps show the utility work (sewer, water, fiber) planned for each block*:
- Stanyan Street to 3rd Avenue
- 3rd Avenue to 8th Avenue
- 8th Avenue to 12th Avenue
- 12th Avenue to 17th Avenue
- 17th Avenue to 22nd Avenue
- 22nd Avenue to 27th Avenue
- 27th Avenue to 32nd Avenue
*Maps do not indicate the exact location on the street where work will occur

Small Business Working Group
The Geary Boulevard Small Business Working Group has been developed to provide a space for merchants and the Project Team to engage on a regular schedule to share updates, explore challenges, discuss ways to reduce impacts and encourage business in the area during construction.
Members must be a business owner or representative of an establishment located on Geary Boulevard between 32nd Avenue and Stanyan Street, or on an adjacent block within this area.
Monthly meetings are focused on coordination between the Project Team and working group members on various topics, including:
- How to reduce construction impacts
- Ways to support businesses and encourage patronage during construction
- Ensuring information from the Project Team is reaching the intended audience, and exploring additional ways to extend reach and impact of project materials and updates
- Sharing updates and upcoming changes in work, sequencing, etc.
Next Meeting:
