Unless specifically defined below, words or phrases used in
this chapter shall be interpreted so as to give them the meanings
they have in common usage and to give this chapter its most reasonable
application.
AH ZONE
Areas subject to inundation by one-percent-annual-chance
shallow flooding (usually areas of ponding) where average depths are
between one and three feet. Base flood elevations (BFEs) derived from
detailed hydraulic analyses are shown in this zone.
AO ZONE
Areas subject to inundation by one-percent-annual-chance
shallow flooding (usually sheet flow on sloping terrain) where average
depths are between one and three feet.
APPEAL
A request for a review of the Township Engineer's interpretation
of any provision of this chapter or a request for a variance.
AREA OF SHALLOW FLOODING
A designated AO or AH Zone on a community's Flood Insurance
Rate Map (FIRM) with a 1% annual or greater chance of flooding to
an average 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.
AREA OF SPECIAL FLOOD HAZARD
Land in the floodplain within a community subject to a 1%
or greater chance of flooding in any given year. It is shown on the
FIRM as Zone V, VE, V1-30, A, AO, A1-A30, AE, A99, or AH.
BASE FLOOD
A flood having a 1% chance of being equaled or exceeded in
any given year.
BASE FLOOD ELEVATION (BFE)
The flood elevation shown on a published Flood Insurance
Study (FIS), including the Flood Insurance Rate Map (FIRM). For Zones
AE, AH, AO, and A1-30, the elevation represents the water surface
elevation resulting from a flood that has a 1% or greater chance of
being equaled or exceeded in any given year.
BASEMENT
Any area of the building having its floor subgrade (below
ground level) on all sides.
BEST AVAILABLE FLOOD HAZARD DATA
The most recent available preliminary flood risk guidance
FEMA has provided. The best available flood hazard data may be depicted
on but not limited to Advisory Flood Hazard Area Maps, Work Maps or
preliminary FIS and FIRM.
BEST AVAILABLE FLOOD HAZARD DATA ELEVATION
The most recent available preliminary flood elevation guidance
FEMA has provided. The best available flood hazard data elevation
may be depicted on an Advisory Flood Hazard Area Map, Work Map or
preliminary FIS and FIRM.
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 supporting foundation system.
DEVELOPMENT
Any man-made change to improved or unimproved real estate,
including but not limited to buildings or other structures, mining,
dredging, filling, grading, paving, excavation or drilling operations,
or storage of equipment or materials located within the area of special
flood hazard.
ELEVATED BUILDING
A nonbasement building built, in the case of a building in
an area of special flood hazard, to have the top of the elevated floor
elevated above the base flood elevation, plus freeboard, by means
of piling, 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 up to the magnitude
of the base flood. In an area of special flood hazard, "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.
ELEVATION CERTIFICATE
An administrative tool of the National Flood Insurance Program
(NFIP) that can be used to provide elevation information, to determine
the proper insurance premium rate, and to support a required letter
of map amendment (LOMA) or letter of map revision based on fill (LOMR-F).
EROSION
The process of gradual wearing away of land masses.
EXISTING MANUFACTURED HOME PARK OR SUBDIVISION
A manufactured home park or subdivision for which the construction
of facilities for servicing the lots on which the manufactured homes
are to be affixed (including, at a minimum, the installation of utilities,
the construction of streets, and either final site grading or the
pouring of concrete pads) is completed before the effective date of
the floodplain management regulations adopted by a community.
FEMA PUBLICATION
Any publication authored or referenced by FEMA related to
building science, building safety, or floodplain management related
to the National Flood Insurance Program. Publications shall include
but are not limited to technical bulletins, desk references, and American
Society of Civil Engineers Standards documents.
FLOOD DESIGN CLASS

inundation of normally dry land areas from:
A.
The overflow of inland or tidal waters; and/or
B.
The unusual and rapid accumulation or runoff of surface waters
from any source.
FLOODPLAIN MANAGEMENT REGULATIONS
Zoning ordinances, subdivision regulations, building codes,
health regulations, special purpose ordinances (such as a floodplain
ordinance, grading ordinance and erosion control ordinance) and other
applications of police power. The term describes such state or local
regulations, in any combination thereof, which provide standards for
the purpose of flood damage prevention and reduction.
FLOODPROOFING
Any combination of structural and nonstructural additions,
changes, or adjustments to structures which reduce or eliminate flood

land areas that must be reserved in order to discharge the base flood
without cumulatively increasing the water surface elevation more than
0.2 foot.
FREEBOARD
A factor of safety usually expressed in feet above a flood
level for purposes of floodplain management. "Freeboard" tends to
compensate for the many unknown factors that could contribute to flood
heights greater than the height calculated for a selected size flood
and floodway conditions, such as wave action, bridge openings, and
the hydrological effect of urbanization of the watershed.
HIGHEST ADJACENT GRADE
The highest natural elevation of the ground surface prior
to construction next to the proposed or existing walls of a structure.
HISTORIC STRUCTURE

on or after the effective date of a floodplain regulation adopted
by a community and includes any subsequent improvements to such structures.
NEW MANUFACTURED HOME PARK OR SUBDIVISION
A manufactured home park or subdivision for which the construction
of facilities for servicing the lots on which the manufactured homes
are to be affixed (including, at a minimum, the installation of utilities,

A.
Built on a single chassis;
B.
Four hundred square feet or less when measured at the longest
horizontal projections;
C.
Designed to be self-propelled or permanently towable by a light-duty

START OF CONSTRUCTION
For other than new construction or substantial improvements
under the Coastal Barrier Resources Act (P.L. No. 97-348), includes substantial improvements and means the date the
building permit was issued, provided the actual start of construction,
repair, reconstruction, rehabilitation, addition, placement, or other
improvement was within 180 days of the permit date. The "actual start"
means either the first placement of permanent construction of a structure
on a site such as the pouring of a slab or footings, the installation
of pilings, the construction of columns, or any work beyond the stage
of excavation, or the placement of a manufactured home on a foundation.
Permanent construction does not include land preparation, such as
clearing, grading and filling nor does it include the installation
of streets and/or walkways, nor does it include excavation for a basement,
footings or 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. 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, a manufactured home, or a gas
or liquid storage tank that is principally aboveground.
SUBSTANTIAL DAMAGE
Damage of any origin sustained by a structure whereby the
cost of restoring the structure to its condition before damage would
equal or exceed 50% of the market value of the structure before the
damage occurred.
SUBSTANTIAL IMPROVEMENT
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.
This term includes structures which have incurred substantial damage,
regardless of the actual repair work performed. The term does not,
however, include either:
A.
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 officer and
which are the minimum necessary to assure safe living conditions;
or
B.
Any alteration of an historic structure, provided that the alteration
will not preclude the structure's continued designation as an
historic structure.
VARIANCE
A grant of relief from the requirements of this chapter that
permits construction in a manner that would otherwise be prohibited
by this chapter.
VIOLATION
The failure of a structure or other development to be fully
compliant with this chapter. A new or substantially improved structure
or other development without the elevation certificate, other certifications,
or other evidence of compliance required in 44 CFR 60.3(b)(5), (c)(4),
(c)(10), (e)(2), (e)(4), or (e)(5) is presumed to be in violation
until such time as that documentation is provided.
WATER SURFACE ELEVATION
The height, in relation to the North American Vertical Datum
(NAVD) of 1988 (or other datum, where specified), of floods of various
magnitudes and frequencies in the floodplains of coastal or riverine
areas.
