Unless specifically defined below, words or phrases used in
this chapter shall be interpreted so as to give them the meaning they
have in common usage and to give this chapter its most reasonable
application.
As used in this chapter, the following terms shall have the
meanings indicated:
A request for a review of the Local Administrator's
interpretation of any provision of this chapter or a request for a
variance.
A designated AO, AH or VO Zone on a community's Flood
Insurance Rate Map (FIRM) with a 1% or greater annual chance of flooding
to an average annual 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.
The land in the floodplain within a community subject to
a 1% 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.
The flood having a 1% chance of being equalled or exceeded
in any given year.
That portion of a building having its floor subgrade (below
ground level) on all sides.
See "structure."
See "basement."
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 of soil, gravel, concrete or other material, must be
equal to or above the lowest adjacent exterior grade. The enclosed
crawl space area shall be properly vented to allow for the equalization
of hydrostatic forces which would be experienced during periods of
flooding.
Any man-made change to improved or unimproved real estate,
including, but not limited to, buildings or other structures, mining,
dredging, filling, paving, excavation or drilling operations or storage
of equipment or materials.
A nonbasement building built, in the case of a building in
Zones 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 Zones 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 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 Zones 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 Zones 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.
A manufactured home park or subdivision for which the construction
of facilities for servicing the lots on which the manufactured homes
are to be affixed (including, at a minimum, the installation of utilities,
the construction of streets, and either final site grading or the
pouring of concrete pads) is complete before the effective date of
the floodplain management regulations adopted by the community.
The preparation of additional sites by the construction of
facilities for servicing the lots on which the manufactured homes
are to be affixed (including the installation of utilities, the construction
of streets, and either final site grading or the pouring of concrete
pads).
The federal agency that administers the National Flood Insurance
Program.
"Flood" or "flooding" also means 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 a flash flood or an abnormal tidal surge, or by some similarly unusual and unforeseeable event which results in flooding as defined in Subsection A(1) of this definition of "flood or flooding."
An Official Map of the community published by the Federal
Emergency Management Agency as part of a riverine community's
Flood Insurance Study. The FBFM delineates a regulatory floodway along
watercourses studied in detail in the Flood Insurance Study.
An examination, evaluation and determination of the flood
hazards and, if appropriate, corresponding water surface elevations,
or an examination, evaluation and determination of flood-related erosion
hazards.
An Official Map of a community, issued by the Federal Emergency
Management Agency, where the boundaries of the areas of special flood
hazard have been designated as Zone A but no flood elevations are
provided.
An Official Map of a community, on which the Federal Emergency
Management Agency has delineated both the areas of special flood hazard
and the risk premium zones applicable to the community.
See "flood elevation study."
Any land area susceptible to being inundated by water from
any source. (See "flooding.")
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.
Has the same meaning as "regulatory floodway."
A use which cannot perform its intended purpose unless it
is located or carried out in close proximity to water, such as a docking
or port facility necessary for the loading and unloading of cargo
or passengers, shipbuilding, and ship repair facilities. The term
does not include long-term storage, manufacturing, sales, or service
facilities.
The highest natural elevation of the ground surface, prior
to construction, next to the proposed walls of a structure.
Any structure that is:

determined by the Secretary of the Interior as meeting the requirements
for individual listing on the National Register;
Certified or preliminarily determined by the Secretary of the
Interior as contributing to the historical significance of a registered
historic district or a district preliminarily determined by the Secretary
to qualify as a registered historic district;

by the Secretary of the Interior; or
Individually listed on a local inventory of historic places

this chapter by granting or denying development permits in accordance
with its provisions. This person is often the Code Enforcement Officer,
Building Inspector or employee of an engineering department.
Lowest floor of the lowest enclosed area (including the basement
or cellar). An unfinished or flood-resistant enclosure, usable solely
for parking of vehicles, building access, or storage in an area other
than a basement area is not considered a building's lowest floor;

in violation of the applicable non-elevation design requirements of
this chapter.

regardless of the actual repair work performed. The term does not,
however, include either:
Any project for improvement of a structure to correct existing
violations of state or local health, sanitary, or safety code specifications
which have been identified by the local code enforcement official
and which are the minimum necessary to ensure safe living conditions;
or

will not preclude the structure's continued designation as an
historic structure.
