Marin County's Sea Level Response Criticized

Marin County is currently evaluating its governance structure to effectively address the pressing issue of sea level rise, as highlighted in a recent report by the Marin County Civil Grand Jury. The report, titled "Sea Level Rise: The Water is Upon Us, We Cannot Run - We Cannot Hide," emphasizes the vulnerability of numerous communities to increasing flooding risks. In response, the county Board of Supervisors has approved measures to enhance readiness and explore collaborative approaches to adaptation. One Shoreline, a collaborative initiative, is working across various jurisdictions to share expertise and secure funding for adaptation projects. Currently, nine projects are underway, focusing on creeks, shorelines, and flood zones. However, the grand jury warns that the complexity of addressing sea level rise may delay essential actions, such as constructing protective barriers and reinforcing critical infrastructure. While the county deliberates on a comprehensive strategy, individual communities are taking steps to mitigate risks. Stinson Beach is actively exploring engineering solutions, while Larkspur and Mill Valley have developed plans addressing greenhouse emissions and climate action, respectively. However, these plans have yet to fully incorporate sea level rise adaptation measures. The grand jury estimates that Marin County will require approximately $17 billion for adaptation efforts. With a new state law mandating coastal local governments to create sea level rise plans by 2034, the urgency for action is clear. Residents in areas like Corte Madera and Sausalito are already experiencing the impacts of rising tides, underscoring the need for immediate and coordinated responses.
