* Special Flood Hazard Area (SFHA) - a term used by the Federal Emergency Management Agency (FEMA) in the National Flood Insurance Program (NFIP) to refer to the land area covered by the floodwaters of the base or 100-year flood (an area of land that has an approximate 1 percent probability of a flood occurring on it in any given year). In these areas flood insurance is generally required.
