<br />. <br /> <br />. <br /> <br />. <br /> <br />F1oodOow-Frequency Curve-A graph showing the number of times per year on the average <br />that floods of certain magnitudes are equaled or exceeded. <br /> <br />Flood Hazard Analyses Report (FHAR) - A flood hazard report prepared by the Natural <br />Resources Conservation Service (formerly, the U.S. Soil Conservation Service) for purposes <br />other than the National Flood Insurance Program. <br /> <br />Flood Hazard Boundary Map (FHBM)- The initial insurance map issued by FEMA that <br />identifies, based on approximate analyses, the areas of the I-percent-annual-chance (IOO-year) <br />flood hazard within a community. <br /> <br />Flood Hazard Mapping Program-The program undertaken by FEMA to conduct FISs and <br />prepare reports and maps delineating flood hazards in floodprone conununities throughout the <br />United States. <br /> <br />Flood Insurance Rate Map (FIRM)- The insurance and floodplain management map <br />produced by FEMA that identifies, based on detailed or approximate analyses, the areas <br />subject to flooding during a I-percent-annual-chance (100-year) flood event in a conununity. <br />Flood insurance risk zones, which are used to compute actuarial flood insurance rates, also are <br />shown. In areas studied by detailed analyses, the FIRM shows Base Flood Elevations (BFEs) <br />to reflect the elevations of the I-percent-annual-chance flood. For many conununities, when <br />detailed analyses are performed, the FIRM also may show areas inundated by O.2-percent- <br />annual-chance (500-year) flood and regulatory floodway areas. <br /> <br />Flood Insurance Rate Zone5- See Flood Insurance Risk Zones. <br /> <br />Flood Insurance Restudy (RFIS)--A revised study of flood hazards performed for a <br />conununity that already has an effective FIRM (and, in some cases, FBFM). An RFIS also <br />may be referred to as a "Type 19 RFIS" or a "Type 19 restudy." FEMA Study Contractors <br />have traditionally performed RFISs. However, communities, regional agencies, and States that <br />are participating in the Cooperating Technical Partner initiative also may perform these types <br />of Flood Map Projects. <br /> <br />Flood Insurance Risk Zones-The zones, also referred to as "risk premium rate zones" and <br />"flood insurance rate zones," shown on a FIRM or FHBM that are used to determine flood <br />insurance premium rates for properties in the conununity covered by the FIRM or FHBM, <br />The flood insurance risk zones include Special Flood Hazard Areas (i.e., Zones A, AI-30, AE, <br />AO, A99, AH, AR, ARIA, ARlAI-30, ARlAE, ARlA99, V, VI-30, VE, YO) and areas <br />outside Special Flood Hazard Areas (i.e., Zones B, X, D, M, N, P, E). <br /> <br />Flood Insurance Study (FIS}-The initial study of flood hazards performed for a community <br />that does not have an effective Flood Insurance Rate Map (FIRM) or Flood Boundary and <br />Floodway Map (FBFM). An FIS also may be referred to as a "Type IS FIS" or a "Type 15 <br />study." FEMA Study Contractors have traditionally performed FISs.
