is alleged that there is an error in any order, requirement, decision,
or determination made by, or failure to act by, the Code Enforcement
Officer or Planning Board in the administration or enforcement of
the provisions of this article. The Board of Appeals may grant a variance
from the requirements of this article consistent with state law and
the following criteria:
A. Variances shall not be granted within any designated regulatory floodway
if any increase in flood levels during the base flood discharge would
result.
B. Variances shall be granted only upon:
(1)
A showing of good and sufficient cause; and
(2)
A determination that should a flood comparable to the base flood
occur, the granting of a variance will not result in increased flood
heights, additional threats to public safety, public expense, or create
nuisances, cause fraud or victimization of the public, or conflict
with existing local laws or ordinances; and
(3)
A showing that the issuance of the variance will not conflict
with other state, federal, or local laws or ordinances; and
(4)
A determination that failure to grant the variance would result
in "undue hardship," which in this subsection means:
(a)
That the land in question cannot yield a reasonable return unless
a variance is granted; and
(b)
That the need for a variance is due to the unique circumstances
of the property and not to the general conditions in the neighborhood;
and
(c)
That the granting of a variance will not alter the essential
character of the locality; and
(d)
That the hardship is not the result of action taken by the applicant
or a prior owner.
C. Variances shall only be issued upon a determination that the variance
is the minimum necessary, considering the flood hazard, to afford
relief, and the Board of Appeals may impose such conditions to a variance
as it deems necessary.
D. Variances may be issued for new construction, substantial improvements,
or other development for the conduct of a functionally dependent use
provided that:
(2)
The structure or other development is protected by methods that
minimize flood damages during the base flood and create no additional
threats to public safety.
E. Variances may be issued for the repair, reconstruction, rehabilitation,
or restoration of historic structures upon the determination that:
(1)
The development meets the criteria of §
335-9.9A through
C; and
(2)
The proposed repair, reconstruction, rehabilitation, or restoration
will not preclude the structure's continued designation as a
historic structure and the variance is the minimum necessary to preserve
the historic character and design of the structure.
F. Variances may be issued for new construction and substantial improvement
of agricultural structures being used for the conduct of agricultural
uses provided that:
(1)
The development meets the criteria of §
335-9.9A through
C; and,
G. Any applicant who meets the criteria of §§
335-9.9A through
C and
335-9.9D,
E, or
F shall be notified by the Board of Appeals in writing over the signature of the Chairman of the Board of Appeals that:
(1)
The issuance of a variance to construct a structure below the
base flood level will result in greatly increased premium rates for
flood insurance up to amounts as high as $25 per $100 of insurance
coverage; and
(2)
Such construction below the base flood level increases risks
to life and property; and
(3)
The applicant agrees in writing that the applicant is fully
aware of all the risks inherent in the use of land subject to flooding,
assumes those risks, and agrees to indemnify and defend the municipality
against any claims filed against it that are related to the applicant's
decision to use land located in a floodplain and that the applicant
individually releases the municipality from any claims the applicant
may have against the municipality that are related to the use of land
located in a floodplain.
H. Appeal procedure for administrative and variance appeals.
(1)
An administrative or variance appeal may be taken to the Board
of Appeals by an aggrieved party within 30 days after receipt of a
written decision of the Code Enforcement Officer or Planning Board.

before the Board of Appeals may take an appeal to Superior Court in
accordance with state laws within 45 days from the date of any decision
of the Board of Appeals.
If any section or provision of this article is declared by the
courts to be invalid, such decision shall not invalidate any other
section or provision of this article.
This article shall not in any way impair or remove the necessity
of compliance with any other applicable rule, ordinance, regulation,
bylaw, permit, or provision of law. Where this article imposes a greater
restriction upon the use of land, buildings, or structures, the provisions
of this article shall control.

of the National Flood Insurance Program.
FLOOD ELEVATION STUDY
An examination, evaluation, and determination of flood hazards
and, if appropriate, corresponding water surface elevations.
FLOOD INSURANCE RATE MAP (FIRM)
An official map of a community, on which the Federal Insurance
Administrator has delineated both the special hazard areas and the
risk premium zones applicable to the community.
FLOOD OR FLOODING
A.
A general and temporary condition of partial or complete inundation
of normally dry land areas from:
(1)
The overflow of inland or tidal waters.
(2)
The unusual and rapid accumulation or runoff of surface waters
from any source.
B.
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 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) of this definition.
FLOODPLAIN MANAGEMENT
The operation of an overall program of corrective and preventive
measures for reducing flood damage, including but not limited to emergency
preparedness plans, flood control works, and floodplain management
regulations.
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
damage to real estate or improved real property, water and sanitary
facilities, structures, and contents.
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, such as wave action, bridge openings,
and the hydrological effect of urbanization of the watershed that
could contribute to flood heights greater than the height calculated
for a selected size flood and floodway conditions.
FUNCTIONALLY DEPENDENT USE
A use which cannot perform its intended purpose unless it
is located or carried out in close proximity to water. The term includes
only docking facilities, port facilities that are necessary for the
loading and unloading of cargo or passengers, and ship building and
ship repair facilities, but does not include long-term storage or
related manufacturing facilities.
HISTORIC STRUCTURE
Any structure that is:
A.
Listed individually in the National Register of Historic Places
(a listing maintained by the Department of Interior) or preliminarily
determined by the Secretary of the Interior as meeting the requirements
for individual listing on the National Register;
B.
Certified or preliminarily determined by the Secretary of the
Interior as contributing to the historical significance of a registered
historic district or a district preliminarily determined by the Secretary
of the Interior to qualify as a registered historic district;
C.
Individually listed on a state inventory of historic places
in states with historic preservation programs which have been approved
by the Secretary of the Interior; or
D.
Individually listed on a local inventory of historic places
in communities with historic preservation programs that have been
certified either:
(1)
By an approved state program as determined by the Secretary
of the Interior, or
(2)
Directly by the Secretary of the Interior in states without
approved programs.
LOCALLY ESTABLISHED DATUM
For purposes of this article, an elevation established for
a specific site to which all other elevations at the site are referenced.
This elevation is generally not referenced to the National Geodetic
Vertical Datum (NGVD), North American Vertical Datum (NAVD), or any
other established datum and is used in areas where mean sea level
data is too far from a specific site to be practically used.
LOWEST FLOOR
The lowest floor of the lowest enclosed area (including basement).
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, provided that
such enclosure is not built so as to render the structure in violation
of the applicable nonelevation design requirements described in § 335-
9.6N of this article.
MANUFACTURED HOME
A structure, transportable in one or more sections, which
is built on a permanent chassis and is designed for use with or without
a permanent foundation when connected to the required utilities. For
floodplain management purposes, the term manufactured home also includes
park trailers, travel trailers, and other similar vehicles placed
on a site for greater than 180 consecutive days.
MEAN SEA LEVEL
For purposes of the National Flood Insurance Program, the
National Geodetic Vertical Datum (NGVD) of 1929, North American Vertical
Datum (NAVD), or other datum to which base flood elevations shown
on a community's Flood Insurance Rate Map are referenced.
MINOR DEVELOPMENT
All development that is not new construction or a substantial improvement, such as repairs, maintenance, renovations, or additions, whose value is less than 50% of the market value of the structure. It also includes but is not limited to: accessory structures as provided for in §
335-9.6L, mining, dredging, filling, grading, paving, excavation, drilling operations, storage of equipment or materials, deposition or extraction of materials, public or private sewage disposal systems or water supply facilities that do not involve structures; and nonstructural projects such as bridges, dams, towers, fencing, pipelines, wharves, and piers.
NATIONAL GEODETIC VERTICAL DATUM (NGVD)
The national vertical datum, whose standard was established
in 1929, which is used by the National Flood Insurance Program (NFIP).
NGVD was based upon mean sea level in 1929 and has been called "1929
Mean Sea Level (MSL)".
NEW CONSTRUCTION
Structures for which the "start of construction" commenced
on or after the effective date of the initial floodplain management
regulations adopted by a community and includes any subsequent improvements
to such structures.
NORTH AMERICAN VERTICAL DATUM (NAVD)
The national datum whose standard was established in 1988,
which is the new vertical datum used by the National Flood Insurance
Program (NFIP) for all new Flood Insurance Rate Maps. NAVD is based
upon the vertical data used by other North American countries such
as Canada and Mexico and was established to replace NGVD because of
constant movement of the earth's crust, glacial rebound and subsidence,
and the increasing use of satellite technology.
RECREATIONAL VEHICLE
A vehicle which is:
A.
Built on a single chassis;
B.
400 square feet or less when measured at the largest horizontal
projection, not including slideouts;
C.
Designed to be self-propelled or permanently towable by a motor
vehicle; and
D.
Designed primarily not for use as a permanent dwelling but as
temporary living quarters for recreational, camping, travel, or seasonal
use.
REGULATORY FLOODWAY
A.
The channel of a river or other water course 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, and,
B.
When not designated on the community's Flood Insurance
Rate Map, it is considered to be the channel of a river or other water
course and the adjacent land areas to a distance of 1/2 the width
of the floodplain, as measured from the normal high-water mark to
the upland limit of the floodplain.
RIVERINE
Relating to, formed by, or resembling a river (including
tributaries), stream, brook, etc.
START OF CONSTRUCTION
The date the building permit was issued, provided the actual
start of construction, repair, reconstruction, rehabilitation, addition,
placement, substantial improvement, 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 slab or footings, the installation of piles, 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 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. 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, or modification of any construction
element, whether or not that alteration affects the external dimensions
of the building.
STRUCTURE
For floodplain management purposes, a walled and roofed building.
A gas or liquid storage tank that is principally above ground is also
a structure.
SUBSTANTIAL DAMAGE
Damage of any origin sustained by a structure whereby the
cost of restoring the structure to its before damage condition 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 official
and which are the minimum necessary to assure safe living conditions;
or
B.
Any alteration of a historic structure, provided that the alteration
will not preclude the structure's continued designation as a
historic structure, and a variance is obtained from the community's
Board of Appeals.
VARIANCE
A grant of relief by a community from the terms of a floodplain
management regulation.
VIOLATION
The failure of a structure or development to comply with
a community's floodplain management regulations.
This article repeals and replaces any municipal ordinance previously
enacted to comply with the National Flood Insurance Act of 1968 (P.L.
90-488, as amended).
The degree of flood protection required by this article is considered
reasonable but does not imply total flood protection.
