Unless specifically defined below, words or phrases used in this chapter shall be interpreted so as to give them the meanings they have in common usage and to give this chapter its most reasonable application.
As used in this chapter, and solely for the purposes of this chapter, the following terms shall have the meanings indicated:
APPEAL
A request for a review of the local administrator's interpretation of any provision of this chapter or a request for a variance from specific provisions thereof.
AREA OF SHALLOW FLOODING
A designated AO, AH, or VO Zone on the Village's Flood Insurance Rate Map (FIRM) and all updates of said map, with a one-percent or greater annual chance of flooding to an average annual depth of one foot 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
The land in the floodplain within the Village subject to a one-percent or greater chance of flooding in any given year. This area may be designated as Zone A, AE, AH, AO, A1 - A30, A99, V, VO, VE or V1-V30. It is also commonly referred to as the "base floodplain" or "one-hundred-year floodplain." For purposes of this chapter, the term “special flood hazard area (SFHA)” is synonymous in meaning with the phrase “area of special flood hazard.”
BASE FLOOD
The flood having a one-percent chance of being equaled or exceeded in any given year.
BASEMENT
A portion of a building partly underground, which has 1/2 or more than 1/2 its height, measured from the finished floor to the finished ceiling, above the mean level of the finished grade around the building. A basement will be deemed a story if the finished ceiling is five feet or more above the mean level of the finished grade around the building. A basement will be deemed habitable if it conforms to all applicable provisions of the New York State Building Code.
BUILDING
Any structure built for support, shelter or enclosure for occupancy or storage. See “structure.”
CELLAR
A portion of a building, partly underground, having 1/2 or more than 1/2 its clear height, from finished floor to finished ceiling, below the mean level of the finished grade around the building.
CRAWL SPACE
An enclosed area beneath the lowest elevated floor, 18 inches or more in height, which is used to service the underside of the lowest elevated floor. The elevation of the floor of this enclosed area, which may be soil, gravel, concrete or other material, must be equal to or above the lowest exterior grade. The enclosed crawl space area shall be properly vented to allow for the equalization of hydrostatic forces experienced during periods of flooding.
CUMULATIVE SUBSTANTIAL IMPROVEMENT
Any reconstruction, rehabilitation, addition, or other improvement of a structure, the cost of which equals or exceeds 50% of the market value of the structure at the time of the improvement or repair when counted cumulatively for 10 years.
DEVELOPMENT
Any man-made change to improved or unimproved real estate, including but not limited to buildings or other structures, mining, dredging, filling, paving, excavation, drilling operations or storage of equipment or materials.
ELEVATED BUILDING
A nonbasement building (i) built, in the case of a building in Zone A1-A30, AE, A, A99, AO, AH, B, C, X, or D, to have the top of the elevated floor or, in the case of a building in Zone V1-30, VE, or V, to have the bottom of the lowest horizontal structure member of the elevated floor, elevated above the ground level by means of pilings, 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 of up to the magnitude of the base flood. In the case of Zone A1-A30, AE, A, A99, AO, AH, B, C, X, or D, "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 floodwaters. In the case of Zone V1-V30, VE, or V, "elevated building" also includes a building otherwise meeting the definition of "elevated building," even though the lower area is enclosed by means of breakaway walls that meet the federal standards.

FLOOD or FLOODING
A general and temporary condition of partial or complete inundation of normally dry land areas from the overflow of inland or tidal waters or the unusual and rapid accumulation or runoff of surface waters from any source. “Flood” or “flooding” also means the collapse or subsidence of land along the shore of a body of water, or waterway, resulting from erosion or undermining of land caused by currents or waves 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 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 above.
FLOODPLAIN or FLOOD-PRONE AREA
Any land area susceptible to being inundated by water from any source. See “flood or flooding.”
FLOODPROOFING
Any combination of structural and nonstructural additions, changes or adjustments to buildings and/or structures which reduces or eliminates flood damage to real estate or improved real property, water and sanitary facilities, buildings and/or structures and their contents.
FLOODWAY
The same meaning as "regulatory floodway."
FLOOR
The top surface of an enclosed area in a building (including a basement or cellar), i.e., the top of the slab in concrete slab construction or the top of wood flooring in wood frame construction.
