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:
ADDITION (TO AN EXISTING BUILDING)
Any walled and roofed expansion to the perimeter of a building
in which the addition is connected by a common load-bearing wall other

appraisal by a professional appraiser.
MANUFACTURED (MOBILE) HOME
A structure, transportable in one or more sections, which

landward of the beach.
SPECIAL FLOOD HAZARD AREA (SFHA)
The land in the floodplain within a community subject to
a one-percent or greater chance of flooding in any given year. Special
flood hazard areas are determined utilizing the base flood elevations
(BFE) provided on the flood profiles in the Flood Insurance Study
(FIS) for a community. Base flood elevations provided on a Flood Insurance
Rate Map (FIRM) are only approximate (rounded up or down) and should
be verified with the BFEs published in the FIS for a specific location.
Special flood hazard areas include, but are not necessarily limited
to, the land shown as Zones A, A1-30, AE, AO and AH and the coastal
high-hazard areas shown as Zones V, V1-30 and VE on a FIRM. The SFHA
is also called the "area of special flood hazard."
START OF CONSTRUCTION
A.
Includes substantial improvement and means the date the building
permit was issued, provided the actual start of construction, repair,
reconstruction or improvement was within 180 days of the permit date.
The actual start means the first placement of permanent construction
of a structure (including a manufactured home) on a site, such as
the pouring of slabs or footings, installation of piles, construction
of columns, or any work beyond the stage of excavation, or placement
of a manufactured home on a foundation. Permanent construction does
not include land preparation, such as clearing, grading or filling;
nor does it include the installation of streets and/or walkways; nor
does it include excavation for a basement, footings, piers or foundations
or the erection of temporary forms; nor does it include the installation
on the property of accessory buildings, such as garages or sheds not
occupied as dwelling units or not part of the main structure.
B.
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.
STRUCTURE
A walled and roofed building that is principally above ground,
a manufactured home, a gas or liquid storage tank, or other man-made
facilities or infrastructure.
SUBSTANTIAL DAMAGE
Damage of any origin sustained by a structure, whereby the
cost of restoring the structure to its pre-damaged condition would
equal or exceed 50% of the market value of the structure before the
damage occurred.
SUBSTANTIAL IMPROVEMENT
Any combination of repairs, reconstruction, alteration, or
improvements to a structure taking place over a ten-year period in
which the cumulative cost equals or exceeds 50% of the market value
of the structure. The market value of the structure should be the
appraised value of the structure using the cost approach to value
method prior to the start of initial repair or improvement or, in
the case of damage, the value of the structure prior to the damage
occurring. For the purposes of this definition, "substantial improvement"
is considered to occur 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 any project for improvement of
a structure required to comply with existing health, sanitary or safety
code specifications which are solely necessary to assure safe living
conditions.
VARIANCE
A grant of relief from the requirements of this chapter which
permits construction in a manner otherwise prohibited by this chapter
where specific enforcement would result in unnecessary hardship.
VIOLATION
The failure of a structure or other development to be fully
compliant with the community's floodplain management ordinance. A
structure or other development without required permits, lowest floor
elevation documentation, floodproofing certificates or required floodway
encroachment calculations is presumed to be in violation until such
time as that documentation is provided.
WATER SURFACE ELEVATION
The height, in relation to the National Geodetic Vertical
Datum (NGVD) of 1929 (or other datum, where specified), of floods
of various magnitudes and frequencies in the floodplains of riverine
areas.
