As used in 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.
AREA OF SHALLOW FLOODING
A designated AO, AH or VO Zone on a community's Flood Insurance
Rate Map (FIRM) with a one-percent 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.
[Amended 5-2-1994 by L.L. No. 1-1994]
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. This area may be designated
as Zone A, AE, AH, AO, A1 through A99, V, VO, VE or V1 through V30. It is
also commonly referred to as the "base floodplain" or "one-hundred-year floodplain."
BASE FLOOD
The flood having a one-percent chance of being equaled or exceeded
in any given year.
BASEMENT
That portion of a building having its flood subgrade (below ground
level) on all sides.
BREAKAWAY WALL
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 the supporting foundation system.
BUILDING
Any structure built for support, shelter or enclosure for occupancy
or storage.
CELLAR
Has the same meaning as "basement."
COASTAL HIGH-HAZARD AREA
The area subject to high-velocity waters, including but not limited
to hurricane wave wash. The area is designated on a FIRM as Zone V1 through
V30, VE, VO or V.
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
located within the areas of special flood hazard.
[Amended 11-14-1994 by L.L. No. 2-1994]
ELEVATED BUILDING
A nonbasement building built, in the case of a building in Zone A1
through 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 through V30, VE or V, to have
the bottom of the lowest horizontal structural 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 Zone A1 through 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 through 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.
[Amended 5-2-1994 by L.L. No. 1-1994]

adopted by a community.
[Added 5-2-1994 by L.L. No. 1-1994]
REGULATORY FLOODWAY
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 a designated height, as determined by the Federal Emergency Management Agency in a Flood Insurance Study or by other agencies as provided in §

SAND DUNES
Naturally occurring accumulations of sand in ridges or mounds landward
of the beach.

planning and design, of any phase of a project or physical alteration of the
property and shall include land preparation, such as clearing, grading and
filling; installation of streets and/or walkways; excavation for a basement,
footings, piers or foundations or the erection of temporary forms. It also
includes the placement and/or installation on the property of accessory buildings
(garages or sheds), storage trailers and building materials. For manufactured

[Added 5-2-1994 by L.L. No. 1-1994]
SUBSTANTIAL IMPROVEMENT

of which equals or exceeds 50% of the market value of the structure, excluding
land values, 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 commence 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:
(1)
Any project for the improvement of a structure to comply with existing
state or local building, fire, health, sanitary or safety code specifications
which are solely necessary to assure safe living conditions; or
(2)
Any alteration of a structure or contributing structure listed on the
National Register of Historic Places or a State Inventory of Historic Places.
VARIANCE
A grant of relief from the requirements of this chapter which permits
construction or use in a manner that would otherwise be prohibited by this
chapter.
