New Flood Maps Effective March 3, 2026
FEMA finalized new flood hazard maps for listed communities (including San Diego County, California) that take effect March 3, 2026. If you own or rent property in those areas, you should check the new maps because changes could affect flood insurance costs and local building rules.
Communities Must Adopt Floodplain Rules to Keep NFIP
FEMA states that the Flood Insurance Rate Map (FIRM) and Flood Insurance Study (FIS) reports are the basis of floodplain management measures a community is required to adopt or show evidence of having in effect in order to qualify or remain qualified for participation in the National Flood Insurance Program (NFIP).
Specific Map Changes: BFEs, Zones, Floodways
The finalized flood hazard determinations may include additions or modifications of Base Flood Elevations (BFEs), base flood depths, Special Flood Hazard Area (SFHA) boundaries or zone designations, or regulatory floodways on the Flood Insurance Rate Maps and, where applicable, in the Flood Insurance Study reports. These technical changes affect how flood insurance rules are applied.
Maps Available at Repositories and Online
The final FIRM and, where applicable, the FIS report for each listed community will be available for inspection at the community map repository addresses (for San Diego County, see listed local offices) and online through the FEMA Map Service Center (https://msc.fema.gov) by March 3, 2026. Interested property owners and lessees are encouraged to review these materials.
