The San Francisco Waterfront is well known for its historical significance. The construction of the Embarcadero Seawall transformed the city into a major trade and financial hub by the end of the 19th century, laying the foundation for a thriving Port of San Francisco (the Port) today.
But the waterfront and the historic seawall beneath the Embarcadero has deteriorated over the past 100 years and is at risk to hazards such as seismic activity, flooding and sea level rise. These immediate and longer-term hazards are being addressed by the Waterfront Resilience Program, a top infrastructure priority for the Port and city.
The Port’s Waterfront Resilience Program allows for the strengthening and adaptation of over seven miles of waterfront including the, more than 3-mile, century-old seawall.
The seawall protects critical regional transportation assets, utilities and over $100 billion in assets and annual economic activity. Time is of the essence as estimates show a 72% chance of a major earthquake happening between now and 2043 and projections of water levels rising more than three and a half feet by 2100.
The Embarcadero’s 100-year-old seawall needs improvements for earthquake safety, near-term flood protection and a plan for long-term resilience and sea level rise adaptation. The first phase of the Seawall Program addresses the most critical life-safety upgrades along the Embarcadero.

“The City and County of San Francisco and the Port have taken this challenge head-on with a strong vision and believe in the urgency of strengthening the Seawall and adapting the waterfront over the next 50 plus years. It’s an amazing opportunity to work for a client that has the foresight and fortitude to make a truly meaningful difference to the citizens it serves for many years to come.”

Protecting the waterfront that protects so much
The Embarcadero waterfront supports historic piers, wharves and buildings, including the historic Ferry Building, all of which are central to the thriving Port. It also supports the Embarcadero Promenade that welcomes millions of people annually from all over the world and provides flood protection to San Francisco’s Financial District and other neighborhoods.
While the Embarcadero is the most well-known area of this waterfront, there is much more to this shoreline. South of the Embarcadero, the waterfront supports thriving communities, world class sports arenas and critical transit facilities - all pivotal to a flourishing, equitable city.
Serving as Program Manager, Jacobs is managing a team of over 30 subconsultants supporting the Port’s program including oversight of the seismic hazard risk assessment, flood assessment, development of the mitigation measures and support of the adaptation and envision planning horizons of 2080 and 2100. Phase I of the Seawall Program evaluates the applicability, effectiveness, risks and costs of the short and mid-term seismic reinforcements and flood mitigations along the waterfront.
The key assets along the seawall also serve critical emergency response and recovery functions, and it supports multiple municipal transportation systems and utility networks. The team are assessing and developing sustainable planning and design for the infrastructure to address the long- term resilience of the waterfront.
Several options being considered for shoreline seismic reliability, which can be implemented together or individually, may include:
-
Ground improvements: improving the soil conditions on the landside of the Seawall, or through/beneath the seawall.
-
Seawall replacement: construction of new Seawall segments, using modern seismic design.
-
Structure improvements: strengthening or replacing bulkhead walls and wharves to withstand seismic movement.
-
Utility relocation or replacement: relocating or replacing critical utilities that are currently protected by the Seawall.
Similarly, there are a range of approaches to reduce flood risk. These could include both “hard solutions” such as raised seawalls, gates, deployable barriers and “soft solutions” such as earthen berms and living shorelines or ecological seawalls.
A collaborative effort
A collaborative approach to the program is essential as our team engages with partner agencies to better understand potential impacts to intersecting infrastructure and assets along the Waterfront and partners with key organizations to secure funding.
The US Army Corps of Engineers in collaboration with the City of San Francisco, developed a first of its kind, San Francisco Waterfront Flood Study and Draft Plan for building a resilient shoreline by analyzing coastal flood risk and the effects of sea level rise (over the next 100 years) along the Port’s 7.5-mile jurisdiction.
Additionally, the collaborative team developed a comprehensive Multi-Hazard Risk Assessment (MHRA). It investigates a range of both earthquake and flood hazard scenarios and evaluates how those scenarios might cause damage and disrupt the transportation and utility infrastructure, buildings and marine structures along the Waterfront as well as affect the lives of the people who live, work and recreate along the Waterfront and shoreline.
Community at the core
Through public awareness and participation, community outreach serves as an integral part of delivering this program. With an equity team working closely with city and county agencies, an equity evaluation framework was developed to prioritize underserved communities, centering equity in the planning process and to inform future stages of the program.
