Flood Risk Identified for Belvedere and Tiburon; Infrastructure Planning Underway
What happened
A firm in San Rafael conducted a levee study that identified flood risks for Belvedere and Tiburon. The City Council received a flood preparation report from city staff, the county, and Pacific Gas & Electric Co. on Monday, October 14, 2026, ahead of the predicted El Niño winter. Belvedere is currently working with the engineering firm to determine the maximum feasible elevation for temporary flood barriers.

Why it matters
The preparations highlight the need for significant infrastructure investment and regulatory planning in coastal areas. Belvedere is exploring temporary flood barrier options for low-lying waterfront infrastructure. Tiburon must also create shoreline adaptation plans, which are influenced by Belvedere's seawall rehabilitation efforts.
Tiburon must create shoreline adaptation plans, supported by a grant from the City Council, influenced by Belvedere seawall rehabilitation.
