interpretation of any provision of this ordinance or a request for
a variance.
AREA OF SHALLOW FLOODING
Shall mean a designated AO, AH, or VO zone on a community's

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
Shall mean 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

Administration has delineated both the areas of special flood hazards
and the risk premium zones applicable to the community.
ELEVATED BUILDING
Shall mean a non-basement building (i) 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 ground level by means of piling,
columns (posts and piers), or shear walls parallel to the flow of

Interior as contributing to the historical significance of a registered
historic district or a district preliminarily determined by the Secretary
to qualify as a registered historic district;
c.

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 on
or after the effective date of the floodplain management regulations
adopted by the municipality.
RECREATIONAL VEHICLE
Shall mean a vehicle which is [i] built on a single chassis;
[ii] 400 square feet or less when measured at the longest horizontal
projections; [iii] designed to be self-propelled or permanently towable

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 piles, the
construction of columns, or any work beyond the stage of excavation,
or the placement of a manufactured home on a foundation.
STRUCTURE
Shall mean a walled and roofed building, a manufactured home,
or a gas or liquid storage tank that is principally above ground.

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 a "historic structure," provided that the
alteration will not preclude the structure's continued designation
as a "historic structure."
VARIANCE
Shall mean a grant of relief from the requirements of this
chapter that permits construction in a manner that would otherwise
be prohibited by this chapter.
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.

at 14 Highland Avenue, Ogdensburg, New Jersey.
[Ord. No. 7-11]
No structure or land shall hereafter be constructed, located,
extended, converted, or altered without full compliance with the terms
of this chapter and other applicable regulations. Violation of the
provisions of this chapter by failure to comply with any of its requirements
(including violations of conditions and safeguards established in
connection with conditions) shall constitute a misdemeanor. Any person

reasonable for regulatory purposes and is based on scientific and
engineering considerations. Larger floods can and will occur on rare
occasions. Flood heights may be increased by man-made or natural causes.
This chapter does not imply that land outside the area of special
flood hazards or uses permitted within such areas will be free from
flooding or flood damages.
This chapter shall not create liability on the part of the Borough
of Ogdensburg, any officer or employee thereof or the Federal Insurance
Administration, for any flood damages that result from reliance on
this chapter or any administrative decision lawfully made thereunder.
[Ord. No. 7-11; New]

portion of said watercourse so the flood carrying capacity is not
diminished.
e. Interpretation of FIRM Boundaries. Make interpretations where needed, as to the exact location of the boundaries of the areas of special flood hazards (for example, where there appears to be a conflict between a mapped boundary and actual field conditions). The person contesting the location of the boundary shall be given a reasonable opportunity to appeal the interpretation as provided in subsection
