About the Urban Watershed Assessment

As part of the Sewer System Improvement Program(SSIP), the San Francisco Public Utilities Commission (SFPUC) is planning infrastructure improvements on both the Bayside and the Westside of San Francisco, in each of San Francisco's eight distinct watersheds. The Urban Watershed Assessment is the watershed-based planning process SFPUC is using to help plan the City’s SSIP, a 20-year, multi-billion dollar project. These improvements will include both "grey" infrastructure such as pipes and tunnels, and "green" infrastructure such as rain gardens and permeable pavement to address such challenges as localized flooding, aging infrastructure, seismic safety and reliability, and water quality in the Bay and Ocean.

 Aging Infrastructure  Seismic Vulnerability  Climate Change Impacts

Aging Infrastructure

Over 80% of our pipes are over 100 years old and the system gets overwhelmed during heavy rains.

Seismic Vulnerability

Our sewer system was not built to withstand a major earthquake. Our sewer pipes and treatment facilities are seismically vulnerable.

Climate Change Impacts

The increasing intensity and frequency of storms can overwhelm our system and contribute to flooding.

Urban Watershed Assessment Process

The Urban Watershed team has engaged San Francisco through a variety of outreach efforts. Check out the reports and recordings below for Bayside and Westside planning activities and then check out our History of SF Urban Watershed Planning page for more information.

Bayside Urban Watersheds Documents

The project team is currently working on the Bayside Urban Watersheds Alternative, which includes improvements for the North Shore, Channel, Islais Creek, Yosemite and Sunnydale Watersheds. The team anticipates presenting the recommended alternative early 2015. Below are reports and webinars from the Characterization and Opportunities Phases of work.
