- AREA OF SPECIAL FLOOD HAZARD
- The land in the floodplain within a community subject to a one-percent-or-greater chance of flooding in any given year. The area may be designated as Zone A on the Flood Hazard Boundary Maps (FHBM). After detailed ratemaking has been completed in preparation for publication of the Flood Insurance Rate Maps (FIRM), Zone A usually is refined into Zones A, AO, A1-A99, VO and V1-V30.
- BASE FLOOD
- The flood having a one-percent chance of being equaled or exceeded in any given year.
- 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.

- For the purposes of determining rates, structures for which the start of construction commenced before the effective date of the FIRM or before January 1, 1975, for FIRM's effective before that date. "Existing construction" may also be referred to as "existing structures."
- (1) A general and temporary condition of partial or complete inundation of normally dry land areas from:
- (2) The collapse or subsidence of land along the shore of a lake or other body of water as a result of erosion or 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 flash flood or an abnormal tidal surge or by some similarly unusual and unforeseeable event which results in flooding as defined in Subsection (1)(a) of this definition.
- Any combination of structural and nonstructural additions, changes or adjustments to structures which reduce or eliminate flood damage to real estate or improved real property, water and sanitary facilities, structures and their contents.
- For floodplain management purposes, a walled and roofed building, including a gas or liquid storage tank, that is principally above ground, as well as a mobile home. "Structure," for insurance coverage purposes, means a walled and roofed building, other than a gas or liquid storage tank, that is principally above ground and affixed to a permanent site, as well as a mobile home on a foundation. For the latter purpose, the term includes a building while in the course of construction, alteration or repair, unless such materials or supplies are within an enclosed building on the premises.

- Any repair, reconstruction or improvement of a structure, the cost of which equals or exceeds 50% of the market value of the structure, either before the improvement or repair is started or, if the structure has been damaged and is being restored, before the damage occurred. For the purposes of this definition, "substantial improvement" is considered to occur when the first alteration of any wall, ceiling, floor or other structural part of the building commences, whether or not that alteration affects the external dimensions of the structure. The term does not, however, include either any project for improvement of a structure to comply with existing state or local health, sanitary or safety code specifications which are solely necessary to assure safe living conditions or any alteration of a structure listed on the National Register of Historic Places or a State Inventory of Historic Places.
