The Flood Hazard Boundary Map (FHBM) is the initial insurance map issued by FEMA that identifies, on the basis of approximate analyses, the areas of 100-year flood hazard in a community. The Flood Insurance Rate Map (FIRM) is the insurance and floodplain management map issued by FEMA that identifies, on the basis of detailed or approximate analyses, the areas of 1 OO-year flood hazard in a community. Actuarial insurance rate zones are also shown. In areas studied by detailed analyses, the FIRM shows BFEs and, occasionally, SOO-year floodplain boundaries, and, on some FIRMs, delineations of the lOO-year floodway boundaries. A Flood Insurance Restudy (RFIS) is a detailed re- evaluation of the flood hazard in a community, which is funded by and performed under contract with FEMA. A Flood Insurance Study (FIS) is an engineering study performed under contract to FEMA to identify flood-prone areas and to determine BFEs, flood insurance rate zones, and other flood risk data for a community. An FIS Contractor is an architectural and engineering firm or Federal, State, or local agency under contract to FEMA to perform an FIS. The floodplain is the area subject to inundation by floodwaters from any source. Floodplain Management is the operation of a program of corrective and preventive measures for reducing flood damage, including emergency preparedness plans, flood-control works, and floodplain management regulations. The Floodway is the channel of a stream, plus any adjacent floodplai n areas, that must be kept free of encroachment so that the 1 DO-year flood discharge can be conveyed without increases of more than a specified amount in the BFE. The Floodway Fringe is the portion of the 100- year floodplain that is not within the floodway and in which development and other forms of encroachment may be permitted under certain circumstances. A hydraulic computer model is a computer program that uses flood discharge values and data concerning floodplain characteristics to simulate flow conditions and determine flood elevations. Hydraulic methodology is used for assessing the movements and behavior of flood waters and determining flood elevations and floodway data. Hydrologic methodology is used for conducting an analysis that determines peak flood discharges and thei r frequencies. A legally described parcel of land is a parcel of land for which a metes and bounds description or a plat has been recorded and on which no structures have been built. A Letter of Map Amendment (LOMA) is an official amendment to an effective NFIP map. A LOMA establishes a property's location in relation to the SFHA. A Letter of Map Revision (LOMR) is an official revision to an effective NFIP map. A LOMR may change flood insurance rate zones, floodplain boundary delineations, planimetric features, and BFEs. The local newspaper is the community newspaper, identified by the CEO, in which FEMA publishes notices at the beginning of an FIS and notices of proposed BFEs. A lot is a parcel of land for which a metes and bounds descri ption or a plat has been recorded and on which one or more structures may have been built. The National Flood Insurance Program (NFIP) is the Federal program that enables property owners to purchase flood insurance. The insurance is designed to provide an alternative to disasteT assistance for meeting the costs of repairing damage to buildings and their contents caused by floods. The NFIP is based on an agreement between the Federal Government and participating communities which states that if a community will carry out measures for reducing future flood risks to new construction in SFHAs, the Federal Government will make flood insurance available within the community B-2
