AREA OF SHALLOW FLOODING " means a designated AO or AH zone on a community's Flood Insurance Rate Map with a one percent or greater chance of flooding to an average depth of one to three feet where a clearly defined channel does not exist, where the path of flooding is unpredictable and where velocity flow may be evident. Such flooding is characterized by ponding or sheet flow.
AREA OF SPECIAL FLOOD HAZARD " means the land in the flood plain within a community subject to a one percent or greater chance of flooding in any given year.
BASE FLOOD " means the flood having a one percent chance of being equaled or exceeded in any given year.
BASEMENT " means any area of the building having its floor subgrade (below ground level) on all sides.
BREAKAWAY WALL " means a wall that is not part of the structural support of the building and is intended through its design and construction to collapse under specific lateral loading forces without causing damage to the elevated portion of the building or supporting foundation system.
DEVELOPMENT " means any man made change to improved or unimproved real estate, including but not limited to buildings or other structures, mining, dredging, filling, grading, paving, excavation or drilling operations, or storage of equipment or materials located within an area of special flood hazard.
ELEVATED BUILDING " means a non-basement building (i) built in the case of a building in an Area of Special Flood Hazard to have the top of the elevated floor elevated above the ground level by means of piling, columns (posts and piers), or shear walls parallel to the flow of the water, and (ii) adequately anchored so as not to impair the structural integrity of the building during a flood up to the magnitude of the base flood. In an Area of Special Flood Hazard "elevated building" also includes a building elevated by means of fill or solid foundation perimeter walls with openings sufficient to facilitate the unimpeded movement of flood waters.

The term describes such State or local regulations, in any combination thereof, which provide standards for the purpose of flood damage prevention and reduction.
FLOODWAY " means 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 cumulatively increasing the water surface elevation more than 0.2 foot.
