Flood Zones & Flood Hazard Awareness

Flood Zone Maps

The current version of the Flood Insurance Rate Maps (FIRMs) is available online on the Federal Emergency Management Agency (FEMA) website. To find a map for a specific address go to FEMA flood map service center.

Flood Insurance

If your property is in a flood hazard area, your mortgage lender may require flood insurance. Flood insurance (offered by FEMA) can be purchased through your local insurance agent (homeowner’s insurance does not cover damage from floods). Additionally, FEMA requires any loans that are Federally-insured to be backed by flood insurance. For more information, please contact the Planning Department at 714-765-5139.

Flood Safety

If severe storm conditions or flooding occurs, don’t go near the Santa Ana River or any of its flood control channels. You can obtain further information about what precautions to take during a flood by logging onto to the City’s Fire Department disaster-preparedness page. You can also learn more about how to prepare for the El Niño season and stay up on the latest by visiting the City's "Be Rain Ready" site. 

Elevation Certifications

Elevation Certificates provide flood elevation data about a structure making it easier for your insurance agent to obtain a more accurate flood-rating determination. To find out if your home or business has an Elevation Certificate on file contact the Building Division at 714-765-5153 or view them online.
