The National Flood Insurance Program (NFIP) requires that floodplain management regulations must be present and enforced in participating communities, and utilize the following definitions, which also apply for the purposes of this chapter:
   (a)   "Flood" or "flooding" means:
      (1)   A general and temporary condition of partial or complete inundation of normally dry land areas from: the overflow of inland or tidal waters, the unusual and rapid accumulation or runoff of surface waters from any source, mudflows, and,
      (2)   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, as defined in this chapter.
   (b)   "Flood Hazard Boundary Map (FHBM)" means an official map of a community, issued by the FEMA, where the boundaries of the flood, mudslide (i.e., mudflow) related erosion areas having special hazards have been designated as Zone A, M, and/or E.
   (c)   "Floodplain" means any land area susceptible to being inundated by water from any source (see definition of "flood").
   (d)    "Floodplain management" means the operation of an overall program of corrective and preventive measures for reducing flood damage, including but not limited to emergency preparedness plans, flood control works, and floodplain management regulations.
   (e)   "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 that provide standards for the purpose of flood damage prevention and reduction.
   (f)   "Structure" means, for floodplain management purposes, a walled and roofed building that is principally above ground, gas or liquid storage facility, as well as a mobile home or manufactured unit.
