For example, EL 3 means the base flood elevation is 3 feet. Underneath each A- or V-zone designation the BFE will be marked as EL, where is a number of feet that varies by location. The BFE is expressed on a flood map as a number of feet. Specifically, flood maps show a community’s flood zone, floodplain boundaries, and base flood elevation. The BFE is identified in the Special Flood Hazard Area, made up of A- and V-zones. Glossary Section: NFIP - National Flood Insurance Program. Base flood elevations are shown as derived from detailed hydraulic analyses (Zone AE is used on new and revised maps in place of Zones A1-A30). For a policy to be issued, the correct premium payment must accompany the Application. The Application is part of the flood insurance policy. This is an area that was previously, and will again, be protected from the 100-year flood by a Federal flood protection system whose restoration is Federally funded and underway.Ī1-A30 - Areas of 100-yr flood base flood elevations and flood hazard factors determined.Ī99 - Areas of 100-yr flood to be protected by flood protection system under construction base flood elevations and flood hazard factors not determined. Flood maps show a community’s risk of flooding. The Application gives information used to determine the eligibility of the risk, the kind of policy to be issued, and the correct premium payment. Flood zones are geographic areas that FEMA has defined according to varying levels of flood risk.

A - Areas of 100-yr flood base flood elevations and flood hazard factors not determined.ĪE - Areas of 100-yr flood base flood elevations have been determined.ĪO - Areas of 100-yr shallow flooding where depths are between one (1) and three (3) feet average depths of inundation are shown, but no flood hazard factors are determined.ĪH - Areas of 100-yr shallow flooding where depths are between one (1) and three (3) feet base flood elevations are shown, but no flood hazard factors are determined.ĪR - An area inundated by flooding, for which BFEs or average depths have been determined.
