What is a Floodplain?
Floodplain means the area adjoining a water course at or below the water surface elevation assocated with the base flood that have been or hereafter may be covered by the base flood. A floodplain is represented by large floods known to have occurred and charateristics of what can be statistically expected to occur on an average frequency of once every 100 years and have water surface elevations equal to those filed with and made a part of the Official Floodplain Maps.
A FIRMette is a full-scale section of a FEMA Flood Insurance Rate Map (FIRM) that you create yourself online by selecting the desired area from an image of a Flood Insurance Rate Map. The FIRMette also includes the map title block, north arrow, and scale bar. There is no charge for making a FIRMette. Because a FIRMette is a full-scale section of an official FEMA Flood Insurance Rate Map, it can be used in all aspects of the NFIP, including floodplain management, flood insurance, and enforcement of mandatory flood insurance purchase requirements.
