USACE Flood Resiliency Study

The U.S. Army Corps of Engineers (USACE) and the Port of San Francisco (Port) have partnered to study flood risk along San Francisco’s bayside shoreline. The USACE Flood Resiliency Study is one of several coordinated waterfront resilience activities being undertaken in partnership with federal, state, and local agencies to plan for anticipated seismic activity, flooding, and sea level rise.

The approximately three- to five-year Flood Resiliency Study will identify vulnerabilities and recommend strategies to reduce current and future flood risks for consideration by the Assistant Secretary of the Army and the U.S. Congress for federal investment and implementation.


USACE/Port Flood Study Goals

  • Better understand current and future flood risk along San Francisco’s bayside shoreline
  • Identify alternatives to reduce flood risk
  • Engage the public and other stakeholders to identify priorities for the Flood Study
  • Create opportunities for funding for flood risk reduction projects

Geographic Area of the Flood Study

Bayview/Islais Creek will experience increased flood risk that could impact transportation and commutes for Bayview residents as well as emergency response and utilities.

Mission Bay/Mission Creek is already experiencing flooding from stormwater and is at risk for severe flooding. As flooding becomes increasingly common and widespread, homes could be directly impacted, as well as key citywide assets such as transportation infrastructure, hospitals, and response facilities and routes.

Embarcadero flooding threatens key utility and transportation infrastructure, including BART, Muni, and ferry networks and critical emergency response and recovery areas as well as economic assets generating over $100 billion in annual economic activity.

Additional Information About the Flood Resiliency Study

  • The Flood Resiliency Study represents an important local and federal partnership to better understand the flood risk along San Francisco’s shoreline. Study costs are shared 50/50 between the USACE and the Port. The detailed cost and schedule for this Study are currently under development.
  • The USACE Flood Resiliency Study will produce flood risk reduction strategies—developed by the USACE, Port, community, local businesses, resource agencies, and other stakeholders—for consideration by the Assistant Secretary of the Army and the U.S. Congress for federal investment and implementation. Alternatives will include a variety of flood risk reduction strategies that respond to feasibility, cost, and local and Federal priorities. Evaluation criteria will consider the economy, the environment, equity, and social issues.
  • At the end of the USACE Flood Resiliency Study, the City and the Port, as well as communities and businesses, will better understand how flooding currently impacts the waterfront, how flood risk changes over time, what the “federal interest” is, and what that means for potential future federal funding.
  • In addition to pursuing funding for “federal interest” projects, the City and the Port plan to use the Flood Study findings to pursue funding for flood risk projects identified but not deemed a “federal interest” by USACE or Congress.
