A request for a review of the local administrator's interpretation
of any provision of this chapter or a request for a variance.
The portion of the special flood hazard area (SFHA) landward
of a V Zone or landward of an open coast without mapped V Zones, in
which the principal sources of flooding are astronomical tides, storm
surges, seiches or tsunamis, not riverine sources. Areas of moderate
wave action may be subject to wave effects, velocity flows, erosion,
scour, or combinations of these forces and are treated as V Zones.
The area of moderate wave action is an area within a Zone AE that
is bounded by a line labeled "Limit of Moderate Wave Action."
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.
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-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."
The flood having a one-percent chance of being equaled or
exceeded in any given year.
That portion of a building having its floor subgrade (below
ground level) on all sides.
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.
See "structure."
Has the same meaning as "basement."
An area within an SFHA, landward of a V1-V30, VE, or V Zone
or landward of an open coast without mapped coastal high hazard areas.
In a Coastal A Zone, the principal source of flood must be astronomical
tides, storm surges, seiches or tsunamis, not riverine flooding. During
the base flood conditions, the potential for breaking wave height
shall be greater than or equal to 1°1/2 feet (457 mm). The inland
limit of a Coastal A Zone is a) the Limit of Moderate Wave Action
if delineated on a FIRM, or b) designated by the authority having
jurisdiction.
[Added 11-2-2023 by L.L. No. 11-2023]
An area of special flood hazard extending from offshore to
the inland limit of a primary frontal dune along an open coast and
any other area subject to high-velocity wave action from storms or
seismic sources. The area is designated on a FIRM as Zone V1-V30,
VE, VO or V. The "coastal high-hazard area" shall also include areas
on a FIRM within a Zone AE that is bounded by a line labeled "Limit
of Moderate Wave Action."
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.
The percentage of any reconstruction, rehabilitation, addition
or other improvement of a structure that equals or exceeds 50% of
the market value of the structure at the time of the improvement or
repair when counted cumulatively since January 1, 1987.
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, or area of moderate wave action, 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.
The federal agency that administers the National Flood Insurance
Program.

Management Agency has delineated both the areas of special flood hazard
and the risk premium zones applicable to the community.
See "flood elevation study."
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) above.
Any land area susceptible to being inundated by water from
any source (see definition of "flooding").

this chapter by granting or denying development permits in accordance
with its provisions. This person is often the building inspector,
code enforcement officer or employee of an engineering department.
The lowest floor of the lowest enclosed area (including 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,

improvements to existing structures, provided that actual start of
construction, repair, reconstruction, rehabilitation, addition placement
or other improvement is within 180 days after the date of issuance.
The actual start of construction means the first placement of permanent
construction of a building (including a manufactured home) on a site,
such as the pouring of a slab or footings, installation of pilings
or construction of columns. Permanent construction does not include
land preparation (such as clearing, excavation, grading, or filling),
or the installation of streets or walkways, or excavation for a basement,
footings, piers or foundations, or the erection of temporary forms,
or the installation of accessory buildings such as garages or sheds
not occupied as dwelling units or not part of the main building. For
a substantial improvement, the actual start of construction means
the first alteration of any wall, ceiling, floor or other structural
part of a building, whether or not that alteration affects the external
dimensions of the building.

tank, that is principally above ground, as well as a manufactured
home.
Damage of any origin sustained by a structure whereby the
cost of restoring the structure to its before-damaged condition would
equal or exceed 50% of the market value of the structure before the
damage occurred. Substantial damage also means flood-related damages
sustained by a structure on two separate occasions during a ten-year
period for which the cost of repairs at the time of such flood event,
on the average, equals or exceeds 25% of the market value of the structure
before the damage occurred.
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 before the start of construction of the improvement.
Substantial improvement also means cumulative substantial improvement.
The term includes structures which have incurred substantial damage,
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 assure safe living conditions;
or
Any alteration of a historic structure, provided that the alteration
will not preclude the structure's continued designation as a historic
structure.
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.
The failure of a structure or other development to be fully
compliant with the community's floodplain management regulations.
