Special flood hazard area - Wikipedia Special flood hazard area A Special Flood Hazard Area ( SFHA ) is an area identified by the United States Federal Emergency Management Agency ( FEMA ) as an area with a special flood or mudflow, and / or flood related erosion hazard, as shown on a flood hazard boundary map or flood insurance rate map. Areas within the SFHA are designated on the flood insurance rate map as Zone A, AO, A1 - A30, AE, A99, AH, AR, AR / A, AR / AE, AR / AH, AR / AO, AR / A1 - A30, V1 - V30 or V. Land areas that are at high risk for flooding are called special flood hazard areas ( SFHAs ), or floodplains. These areas are indicated on flood insurance rate maps ( FIRMs ). In high - risk areas, there is at least a 1 in 4 chance of flooding during a 30 - year mortgage. References Jump up ^ United States of America ( 2002 ).
