The flooding that occurred in Marin County on January 3–4, 2026 demonstrates the increasing impacts of sea level rise on shoreline communities in the Bay Area. With extensive coastline, low-lying development, and reduced funding available to protect communities and infrastructure, Marin County faces complex near- and long-term challenges that other Bay Area cities and counties are also confronting. These shared challenges highlight the value of a countywide agency like OneShoreline in coordinating stakeholders and advancing multi-jurisdictional shoreline resilience projects.
