Flood Insurance Rate Maps (FIRMs), sometimes called flood risk maps, are available online at FEMA’s map service center or This information will help you determine whether your property is in a Special Flood Hazard Area, whether you will be required or should purchase flood insurance, and what risk you may face from future flood events.

What is my BFE? The What’s My BFE? tool from the Federal Emergency Management Agency (FEMA) helps you to identify the Base Flood Elevation for your structure. The base flood elevation identifies how high the water is likely to rise during a 1% chance flood. The BFE is used in determining the required elevation of any new or substantially improved structure. The BFE helps determine insurance premiums in the National Flood Insurance Program (NFIP). You can find your BFE by entering your address into FEMA’s online “What is my BFE” tool found at Some municipalities also have BFE records on file.
