FEMA Special Flood Hazard Area Information

FEMA special flood hazard area is area's in the Napa County that have 1.0-percent (100 year flood) and 0.2-percent (500 year flood) chance of flooding every year. The goal of the Engineering Division is to ensure the protection of life and property for those who are situated in these areas. By following the guidelines set forth, the County of Napa is given a Community Rating System (CRS) credit. The higher CRS credit the County is given, the greater a discount the community is given for flood insurance. Napa County's current CRS is 7. By working together, we all strive towards educating ourselves and helping the community.

Please find more information on how you can participate at Napa Flood & Water Resources.
