San Francisco Waterfront Flood Study

The U.S. Army Corps of Engineers (USACE), in collaboration with the City of San Francisco, are conducting a Flood Study to analyze the coastal flood risk and effects of sea level rise for the 7.5 miles of waterfront within the Port of San Francisco's jurisdiction, from Aquatic Park to Heron's Head Park. The San Francisco Waterfront Flood 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 study will identify vulnerabilities and recommend strategies to reduce current and future flood risks for consideration for federal investment and implementation along the Port's entire 7.5 mile jurisdiction. 

San Francisco Waterfront 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 stakeholders to identify priorities for the Flood Study
  • Create opportunities for funding for flood risk reduction projects

San Francisco Waterfront Flood Study - Draft Plan

Reflecting more than six years of community engagement and public input, the Draft Plan proposes actions to defend the shoreline against rising sea levels and presents an environmental analysis of those actions. 

The Draft Plan indicates where to build coastal flood defenses and how much sea level rise future coastal flood defenses will manage before they need to be adapted to higher water levels. The proposed solutions are estimated to cost $13 billion, and, if approved by Congress, the Federal government may pay up to 65% of the construction cost. Cost estimates are preliminary, high-level, and subject to change.

Learn more about the Draft Plan, including ways to share feedback. USACE and the City are seeking public comment on the Draft Plan and Environmental Review through March 29, 2024.
