variance.
A designated AO or VO Zone on a community's Flood Insurance
Rate Map (FIRM) with base flood depths from one to three 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.
Is 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, AR, AO, A1-99, V, VO, VE, or V1-30.

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.
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.
Any structure built for support, shelter, or enclosure for
occupancy or storage.
Has the same meaning as "basement."
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.
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.
A non-basement 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.
A general and temporary condition of partial or complete

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 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.
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.
Is the official report provided by the Federal Emergency
Management Agency. The report contains flood profiles, as well as
the Flood Boundary Floodway Map and the water surface elevations of
the base flood.
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."

in violation of the applicable nonelevation design requirements of
this chapter.

intended to be improved property.
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.
Has the same meaning as "manufactured home."
As corrected in 1929; is a vertical control used as a reference
for establishing varying elevations within the floodplain.
Structures for which the start of construction commenced
on or after the effective date of this chapter.
Has the same meaning as "base flood."
That at least 51% of the actual cash value of the structure,
excluding land value, is above ground.
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 § 93-12B of this chapter.
Naturally occurring accumulations of sand in ridges or mounds
landward of the beach.
The initiation, excluding planning and design, of any phase

homes, the "actual start" means affixing of the manufactured home
to its permanent site.
A walled and roofed building, a manufactured home, or a gas

For the purposes of this definition, "substantial improvement"
