A reference guide to flood zones and flood insurance requirements, with links to the official FEMA flood maps.
Understanding Flood Risk Maps
This reference guide explains the flood data that matters for insurance: FEMA flood zones, base flood elevations, flood history, and elevation certificates. To look up the official flood map for a specific address, use the FEMA Flood Map Service Center linked below.
FEMA Flood Zone ID
FEMA flood zones classify a property's flood risk. Look up the zone for any address on the official FEMA Flood Map Service Center.
Base Flood Elevation
Base flood elevation is the height floodwater is expected to reach in a 1%-annual-chance flood, and it is critical for determining flood insurance requirements.
Historical Flood Events
A property's flood history, alongside its current zone, helps show how exposed it really is.
Elevation Certificates
An elevation certificate documents a building's elevation relative to the base flood elevation and is used to rate flood insurance.
