FEMA flood zone rules in Marin County, CA — also called floodplain regulations or special flood hazard area (SFHA) rules — determine flood insurance requirements and elevation standards for new construction.
Marin County participates in the FEMA National Flood Insurance Program. Development in mapped Special Flood Hazard Areas (Zones A and AE) must comply with the Floodplain Management Ordinance in Title 23 of the Marin County Code, requiring elevation certificates and finished-floor elevations above the Base Flood Elevation.
Marin County participates in the National Flood Insurance Program and enforces floodplain rules under Title 23 of the Marin County Code. Special Flood Hazard Areas (SFHAs) — Zones A and AE on the FEMA Flood Insurance Rate Maps — cover portions of low-lying areas around San Rafael, San Geronimo Valley, Marshall, Olema, Stinson Beach, and shoreline communities. New construction and substantial improvements in SFHAs require permits demonstrating that the lowest finished floor is at or above the Base Flood Elevation plus required freeboard. Coastal communities also face mounting sea-level-rise exposure: Novato, Mill Valley, Corte Madera and San Rafael are projected among the earliest Bay Area flooding sites.
Construction in a Special Flood Hazard Area without floodplain development approval violates Title 23. CDA may halt work, require post-construction elevation certificates, and order modifications. Continued violation jeopardizes the county's NFIP participation and increases insurance premiums for all county residents.
