What is the base flood elevation defined as?

The base flood elevation (BFE) is defined as the elevation associated with the 100-year flood, which has a 1% chance of being equaled or exceeded in any given year. This measurement is used in floodplain management to determine the minimum elevation that construction should be built to in order to mitigate flood risk. By establishing the BFE, communities and individuals can make informed decisions about construction, zoning, and planning in flood-prone areas.

The significance of the 100-year flood classification is central to regulations and insurance requirements under the National Flood Insurance Program (NFIP), which guides local governments in development decisions and helps property owners understand their flood risks and potential insurance needs.
