San Francisco Draft Waterfront Adaptation Strategies

San Francisco, CA

Back to

The Port of San Francisco, in partnership with the U.S. Army Corps of Engineers and San Francisco city agencies, has developed seven Draft Waterfront Adaptation Strategies based on over five years of public engagement. From these strategies the Port and City will identify a preferred approach to reduce flood risks from sea level rise and extreme storms and guide the transformation of the city’s shoreline and bayside neighborhoods over the next century.

An Urgent Call to Action + Open Space Opportunity

To defend San Francisco from current and future flood risks, there is a need to adapt the shoreline to address up to seven feet of sea level rise projected by 2100. Any effort aimed at long-term sea level rise resilience should also strengthen the waterfront against the urgent earthquake risk we face today. The scale of change necessary provides a once in a generation opportunity to not only defend our city from flood and earthquake risks, but also to rejuvenate the waterfront, improve the City’s connection to the Bay, and bring co-benefits such as improved public open space, increased waterfront access, enhanced mobility, while also increasing safety, ecological health, and job opportunities.

Working alongside diverse and collaborative teams of engineers, urban designers, planners, and public engagement specialists, CMG brings a holistic, landscape-driven approach to the process of adaptation planning and risk mitigation. CMG’s efforts in support of the adaptation strategy development process are multi-faceted – ranging from process design, public engagement, and narrative development to technical analysis and ecological planning.

The San Francisco shoreline is characterized by varying levels of risk, diverse topography, historic conditions, and urban character. As such, there is no single approach to adaptation that will meet the needs of San Francisco along the entire waterfront. The seven Draft Waterfront Adaptation Strategies developed by the Port and City in partnership with the U.S. Army Corps of Engineers are intended to respond to these variable conditions with a broad range of policy-based and constructed measures ranging from ‘grey’ to ‘green.’ These strategies use different methods to achieve the goals of reducing flood risk and increasing flood resilience. Over the coming months, strategies will be evaluated by the public through a series of in-depth engagements. The Port and U.S. Army Corps of Engineers will also complete preliminary economic and environmental analyses to inform future decision making.

This program represents different approaches to addressing the same risks and to identify a cost-effective approach to risk reduction while also achieving public realm and community benefits. The intent is not to choose one – rather, it is to select the ideas that best serve our city and communities and hybridize those ideas into a unified Waterfront Adaptation Plan that will guide our city into the next century.

What happens along the San Francisco Waterfront impacts San Franciscans in every corner of the city. The scale of change necessary provides a once in a generation opportunity to not only defend our waterfront, but also to achieve of the Waterfront Resilience Program’s broader goals related to equity, ecology, and access, and community benefit.

The preliminary preferred Waterfront Adaptation Plan is anticipated to undergo environmental review (NEPA/CEQA review) through 2025 – at which point a Final Waterfront Adaptation Plan will be created and presented to the U.S. Congress for potential federal funding of up to 65% of the project cost.
