Coastal Flooding Information

Base Flood Elevation

Base Flood Elevation is the computed elevation to which floodwater is anticipated to rise during the base flood. Base Flood Elevations (BFEs) are shown on Flood Insurance Rate Maps (FIRMs) and on the flood profiles.

The BFE is the regulatory requirement for the elevation or floodproofing of structures. The relationship between the BFE and a structure's elevation determines the flood insurance premium. Click HERE to learn more.

Coastal Mapping

The effects of tides, combined with large amounts of water and waves from storms make coastal areas some of the most at-risk areas for flooding. To map coastal flood hazards accurately, many factors must be taken into account, such as the amount of development in the area, the types and strength of storms that historically have affected the area, and onshore and offshore elevations.
