Base Flood Elevation (BFE)

What is a Base Flood Elevation (BFE), and how do I find the BFE for my property?


The BFE is the computed elevation to which flood waters are anticipated to rise during the base (1-percent-annual-chance) flood event. BFEs, typically rounded to the nearest whole foot, are shown on the flood map for areas where a detailed study has been completed. The BFE can be shown as a number on top of a black wavy line that bisects the floodplain, in parentheses underneath the zone label, or on top of a black straight line that bisects the flood plain. Examples of the two lines with BFE values may be seen below:

The BFE is the regulatory requirement for the elevation or flood proofing of structures. The relationship between the BFE and a structure's elevation determines the flood insurance premium. For more specific BFE data, consult the Flood Insurance Study report for a given community.
