Step 5: Identify the Base Flood Elevation at the Property

To estimate the BFE at his property, Carlo can use the BFE lines (labels) shown near the property on the flood map. For example, if BFE lines 109 and 110 are near the property, and 110 is the nearer of the two, Carlo can estimate that the BFE at the property is approximately 110 feet above mean sea level (using NGVD of 1929).

The BFE numbers shown on the flood map are round numbers and are generally no more accurate than plus or minus a half foot. For an accurate BFE, Carlo, or a licensed professional he has hired, will need to refer to the Flood Profiles in the Flood Insurance Study (FIS).

The base flood elevations (BFEs) lines closest to a property are highlighted on a Flood Insurance Rate Map panel. The BFE line showing 110 feet is closest to property and structure.
