Base Flood Elevation
10/07/26
“Why does FEMA care about the water elevation level resulting from a one-hundred-year flood?”
U.S. FEMA quantifies a one-hundred-year flood as one with a one percent chance of happening in a given year. The water level elevation above sea level resulting from that flood is called the Base Flood Elevation, or BFE. FEMA publishes BFEs in its maps. If your building is at or below the BFE, you will likely face higher flood insurance premiums. New development that affects hydrology can alter the BFE for a local area.
