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 or VO Zone on a community's Flood Insurance
Rate Map (FIRM), with base flood depths from one (1) to three (3) feet, where
a clearly defined channel does not exist, where the path of flooding is unpredictable
and indeterminate and where velocity flow may be evident.
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 -99, V, VO, VE or V1 - 30. 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 floor 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
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 - 30,
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 or drilling operations located within the area of special
flood hazard.
ELEVATED BUILDING
A nonbasement building built to have the lowest floor elevated above
the ground level by means of fill, solid foundation perimeter walls, pilings,
columns (posts and piers) or shear walls.
FLOOD BOUNDARY AND FLOODWAY MAP (FBFM)
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.
FLOOD or FLOODING
A general and temporary condition of partial or complete inundation
of normally dry land areas from:
(1)
The overflow of inland or tidal waters; or
(2)
The unusual and rapid accumulation or runoff of surface waters from
any source.
FLOOD HAZARD BOUNDARY MAP (FHBM)
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
defined but no water surface elevation is provided.
FLOOD INSURANCE RATE MAP (FIRM)
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.
FLOOD INSURANCE STUDY
The official report provided by the Federal Emergency Management
Agency. The report contains flood profiles, as well as the Flood Boundary
and Floodway Map and the water surface elevations of the base flood.
FLOODPROOFING
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.
FLOODWAY
The same meaning as "regulatory floodway."
FLOOR
The top surface of an enclosed area in a building, including basement,
i.e., the top of the slab in concrete slab construction or the top of wood
flooring in wood frame construction.
FUNCTIONALLY DEPENDENT USE
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. The term does not include long-term storage, manufacture,
sales or service facilities.
HIGHEST ADJACENT GRADE
The highest natural elevation of the ground surface, prior to construction,
next to the proposed walls of a structure.
LOWEST FLOOR
The lowest level, including basement or cellar, of the lowest enclosed
area. An unfinished or flood-resistant enclosure, usable solely for the parking
of vehicles, building access or storage in an area other than a basement is
not considered a building's "lowest floor," provided that such enclosure
is not built so as to render the structure in violation of the applicable
nonelevation design requirements of this chapter.
MANUFACTURED HOME
A structure, transportable in one (1) or more sections, which is
built on a permanent chassis and designed to be used with or without a permanent
foundation when connected to the required utilities. The term also includes
park trailers, travel trailers and similar transportable structures placed
on a site for one hundred eighty (180) consecutive days or longer and intended
to be improved property.
MEAN SEA LEVEL
For purposes of the National Flood Insurance Program, the National
Geodetic Vertical Datum (NGVD) of 1929 or other datum to which base flood
elevations shown on a community's Flood Insurance Rate Map are referenced.
NEW CONSTRUCTION
Structures for which the start of construction commenced on or after
the effective date of this chapter.
PRINCIPALLY ABOVE GROUND
At least fifty-one percent (51%) of the actual cash value of the
structure, excluding land value, is above ground.
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 §
54-12B of this chapter.
SAND DUNES
Naturally occurring accumulations of sand in ridges or mounds landward
of the beach.
START OF CONSTRUCTION
The initiation, excluding 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 homes, the "actual start" means affixing
the manufactured home to its permanent site.
STRUCTURE
A walled and roofed building, a manufactured home or a gas or liquid
storage tank that is principally above ground.
SUBSTANTIAL IMPROVEMENT
Any repair, reconstruction or improvement of a structure, the cost
of which equals or exceeds fifty percent (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 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 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.
