Home Browse Search

Flood or flooding also includes the collapse or subsidence of land along the shore of a lake or similar body of water as a result of erosion or undermining caused by waves or current of water exceeding anticipated cyclical levels that result in a flood as defined above. (24) Flood hazard area means areas subject to the one percent(1%)annual chance flood. (See "Special Flood Hazard Area") (25) Flood Insurance Rate Map (FIRM) means an official map of a community, on which FEMA has delineated both the areas of special flood hazard and the risk premium zones applicable to the community. A FIRM that has been made available digitally is called a Digital Flood Insurance Rate Map(DFIRM). (26) Flood Insurance Study (FIS) means the official hydraulic and hydrologic report provided by FEMA. The report contains flood profiles,as well as the FIRM and the water surface elevation of the base flood. (27) Flood prone area means any land area acknowledged by a community as being susceptible to inundation by water from any source. (See"Floodplain") (28) Flood Protection Grade(FPG) is the BFE plus two (2) feet at any given location in the SFHA. (See"Freeboard") (29) Flood-related erosion means the collapse or subsidence of land along the shore of a lake or other body of water as a result of undermining caused by waves or currents of water exceeding anticipated cyclical levels or suddenly caused by an unusually high water level in a natural body of water, accompanied by a severe storm, or by an unanticipated force of nature, such as a flash flood or an abnormal tidal surge or by some similarly unusual and unforeseeable event which results in flooding. (30) Floodplain or flood prone area means any land area susceptible to being inundated by water from any source. (See"Flood") (31) Floodplain management means the operation of an overall program of corrective and preventive measures for reducing flood damage and preserving and enhancing, where possible, natural resources in the floodplain, including but not limited to emergency preparedness plans, flood control works, floodplain management regulations, and open space plans. (32) Floodplain management regulations means zoning ordinances,subdivision regulations, building codes, health regulations, special purpose ordinances (such as a floodplain ordinance, grading ordinance and erosion control ordinance), and other applications of police power which control development in flood-prone areas. The term describes such state or local regulations in any combination thereof, which provide standards for the purpose of flood damage prevention and reduction. (33) Floodproofing(dry floodproofing)is a method of protecting a structure that ensures that the structure, together with attendant utilities and sanitary facilities, is watertight to the floodproofed design elevation with walls that are substantially impermeable to the passage of water. All structural components of these walls are capable of resisting hydrostatic and hydrodynamic flood forces, including the effects of buoyancy, and anticipated debris impact forces. (34) Floodproofing certificate is a form used to certify compliance for non-residential structures as an alternative to elevating structures to or above the FPG. (35) Floodway is the channel of a river or other watercourse and the adjacent land areas that must be reserved in order to discharge the base flood without cumulative increasing the water surface elevation more than a designated height. (36) Freeboard means a factor of safety, usually expressed in feet above the BFE, which is applied for the purposes of floodplain management. It is used to compensate for the many unknown factors that could contribute to flood heights greater than those calculated for the base flood. (37) Fringe or Flood Fringe is the portion of the floodplain lying outside the floodway. 5
