Sausalito Faces Rising Sea Levels: Urgent Adaptation Needed

Sausalito is confronting significant challenges due to rising sea levels, as revealed in a recent community forum focused on potential adaptation strategies. City consultants presented a stark assessment of the situation, indicating that the area has experienced a rise of 5 inches in sea level since 1975, with projections suggesting an increase of nearly 10 inches in the next 25 years. The forum, attended by approximately 75 residents, highlighted the urgent need for comprehensive planning to mitigate the impact of rising waters.

At the meeting, John Gibbs, an urban designer with the consulting firm WRT, discussed the potential for storm surges to exacerbate flooding, predicting surges could exceed 6 feet by 2100. This combined with the anticipated rise in water levels could mean the bay’s surface might reach 3 feet higher than current levels. The city is now tasked with exploring resilience strategies that not only protect its waterfront but also preserve its unique character and commerce.

The focus of the discussion revolved around a draft shoreline adaptation plan, presented by Catie Thow Garcia, the city’s resiliency and sustainability manager. “Tonight our real purpose is to view the draft shoreline adaptation plan,” she stated. The planning process has included multiple community meetings and focus groups to engage residents in the discussion on future options.

Identifying Vulnerabilities and Potential Solutions

Consultants outlined vulnerabilities across four key zones: the southern bayfront and promenade, New Town, Gate 5 Road and Varda Landing Road, and floating homes at Gate 6 Road and 6 1/2 Road. Central to the discussion was the concept of a “resilient edge.” Gibbs emphasized the importance of determining how high protective structures should be, as well as the implications of building walls or levees.

Options for adaptation include creating offshore floating barriers, fortifying piers, and elevating structures and roads. For instance, the city’s main thoroughfare, Bridgeway, currently averages 12 feet above sea level, but in some areas, it may need to serve as a sea wall. The draft plan also identifies specific vulnerabilities, such as the erosion of sand at Swede Beach and the potential flooding of the Spinnaker restaurant and other businesses along the waterfront.

Gibbs provided an overview of the challenges facing the area, stating, “That was a short synopsis of some dreary news. But hopefully in there, knowledge is power.” The consultants are soliciting written public comments until October 7, 2023, and plan to present the final plan to the City Council in November 2023.

Community Response and Concerns

Reactions to the proposals have varied. According to architect Marco Esposito, the presented options aim to protect the character and businesses of Sausalito while addressing vulnerabilities. He mentioned that some neighborhoods could see the construction of new peninsulas instead of traditional sea walls.

Nevertheless, concerns were raised by several marina owners, including Casey Pedersen of Clipper Yacht Harbor, about the focus on sea walls and levees. He argued that the proposals could severely impact the working waterfront, stating, “Critical infrastructure is gone. Parking is gone. Fuel docks are gone. Boat yards are gone. Marinas are gone.”

Gibbs acknowledged the feedback, stating, “We’re open and we’re available to do that,” indicating a willingness to engage with local stakeholders further.

As Sausalito grapples with the realities of climate change and rising sea levels, the community remains engaged in discussions about how to best adapt and protect its future. The outcomes of the upcoming City Council meeting will be critical in shaping the city’s approach to resilience and sustainability moving forward.
