and development of flood-prone areas in such a manner as to minimize
future flood blight areas;
g. To ensure that potential home buyers are notified that property is
in an area of special flood hazard; and
h. To ensure that those who occupy the areas of special flood hazard
assume responsibility for their actions.
[Ord. No. 0-19-82 § 2]
In order to accomplish its purposes, this chapter includes methods
and provisions for:
a. Restricting or prohibiting uses which are dangerous to health, safety,
and property due to water or erosion hazards, or which result in damaging
increases in erosion or in flood heights or velocities;
b. Requiring that uses vulnerable to floods, including facilities which
serve such uses, be protected against flood damage at the time of
initial construction;
c. Controlling the alteration of natural floodplains, stream channels,
and natural protective barriers, which are involved in the accommodation
of flood waters;
d. Controlling filling, grading, dredging and other development which
may increase flood damage; and

As used in this section:
APPEAL
A request for a review of the interpretation of any provision
of this chapter or a request for a variance.
AREA OF SHALLOW FLOODING
A designated AO 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; or the path of flooding
is unpredictable and indeterminate; and where velocity flow may be
evident.
BASE FLOOD
The flood having a one-percent chance of being equaled or
exceeded in any given year.
BASEMENT
Any area of the building where its floor subgrade is below
level on all sides.
BREAK AWAY 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
elevation 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 and other structures, mining,
dredging, filling, grading, paving, excavation or drilling operations
located within the area of special flood hazard.
ELEVATED BUILDING
A nonbasement building (i) built in the case of a building
in an area of special flood hazard to have the top of the elevated
floor wherein the case of the building in a coastal high hazard area
to have the bottom of the lowest horizontal structural member of the
elevated floor elevated above the ground level by means of piling,
columns (posted and piers), or shear walls parallel to the flow of
the water and (ii) adequate anchoring as not to impair the structural
integrity of the building during a flood of up to the magnitude of
the base flood. In an area of special flood hazard "elevated building"
also includes a building otherwise meeting the definition of "elevated
building" even though the lower area is enclosed by means of break
away walls.
FLOOD OR FLOODING
A general and temporary condition of partial or complete
inundation or normally dry land areas from:
a.
The overflow of inland or tidal waters or
b.
The unusual and rapid accumulation of runoff or surface waters
from any source.
FLOOD INSURANCE RATE MAP (FIRM)
The official map on which the Federal Insurance Administration
has delineated both the areas of special flood hazards and the risk
premium zones applicable to the Township.
FLOOD INSURANCE STUDY
The official report provided to the Township in which the
Federal Insurance Administration has provided flood profiles, as well
as the Flood Boundary-Floodway Map and the water surface elevation
of the base flood.
FLOODWAY
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 elevations more
than 0.2 feet.
LOWEST FLOOR
The lowest floor of the lowest enclosed area including basement.
An unfinished or flood resistant enclosure useable solely for the
parking of vehicles, building access or storage in an area other than
a basement is not considered a building lowest floor provided that
such enclosure is not built so to render the structure in violation
in other applicable nonelevation design requirements.
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, then connected to the required utilities.
For floodplain management purposes the term "manufactured homes" also
includes park trailers, travel trailers and other similar vehicles
placed on a site for greater than 180 consecutive days. For insurance
purposes the term "manufactured home" does not include park trailers,
travel trailers and other similar vehicles.
NEW CONSTRUCTION
Structures for which the "start of construction" commenced
on or after the effective date of this chapter.
START OF CONSTRUCTION
A first placement of permanent construction of a structure
on a site, such as the pouring of slabs or footings or any work beyond
the state of excavation. 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, 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 as part of the main structure. For a structure without
a basement or poured footings, the "start of construction" includes
the first permanent framing or assembly of the structure or any part
thereof on its piling or foundation.
START OF CONSTRUCTION (FOR OTHER THAN NEW CONSTRUCTION OR SUBSTANTIAL
IMPROVEMENTS UNDER THE COASTAL BARRIER RESOURCES ACT. (P.L. 97-248))
Includes substantial improvement and means the date the building
permit was issued, provided the actual start of construction, repair,
reconstruction, 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 footing, 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 sidewalks,
nor does it include excavation for a basement, footing, piers, or
foundations or 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.
STRUCTURE
A walled and roofed building that is principally above ground.
SUBSTANTIAL IMPROVEMENT
Any repair, reconstruction or improvement of a structure,
the cost of which equals or exceeds 50% of the market value of the
structure either:
a.
Before the improvement or repair is started, or
b.
If the structure has been damaged and is being restored, before
the damage occurred.
|
For 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 the alteration affects the external dimensions of the structure.
|
|
The term does not, however, include either:
|
|
a.
|
Any project for improvement of a structure to comply with existing
State or local health, sanitary or safety code specifications which
are solely necessary to assure safe living conditions, or
|
|
b.
|
Any alteration of a structure listed on the National Register
of Historic Places or a State Inventory of Historic Places.
|
VARIANCE
A grant of relief to a person 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.

[Ord. No. 0-19-82 § 10A]
In all areas of special flood hazards the following standards
are required:
a. Anchoring.
1. All new construction and substantial improvements shall be anchored
to prevent flotation, collapse, or lateral movement of the structure.
2. All manufactured homes shall be anchored to resist flotation, collapse,
or lateral movement. Methods of anchoring may include, but are not
limited to, use of over the top or frame ties to ground anchors. This
requirement is in addition to applicable State and local anchoring
requirements for resisting wind forces.
b. Construction materials and methods. All new construction and substantial
improvements shall be constructed with materials and utility equipment
resistant to flood damage, and by methods and practices which minimize
flood damage.
c. Utilities.
1. All new and replacement water supply systems shall be designed to
minimize or eliminate infiltration of flood waters into the systems.
2. New and replacement sanitary sewer systems shall be designed to minimize
or eliminate infiltration of flood waters into the systems and discharge
from the systems into flood waters.
3. On-site waste disposal systems shall be located to avoid impairment
to them or contamination from them during flooding.
4. Electrical, heating, ventilations, plumbing and air conditioning
equipment and other service facilities shall be designed and/or located
as to prevent water from entering or accumulating within the components
during conditions of flooding.
d. Subdivision proposals.
1. All subdivision proposals shall be consistent with the need to minimize
flood damage;
2. All subdivision proposals shall have public utilities and facilities
such as sewer, gas, electrical and water systems located and constructed
to minimize flood damage;
3. All subdivision proposals shall have adequate drainage provided to
reduce exposure to flood damage; and
4. Base flood elevation data shall be provided for subdivision proposals
and other proposed development which contain at least 50 lots or five
acres (whichever is less).
[Ord. No. 0-19-82 § 10B; Ord.
No. 0-12-88 § 6]
In all areas of special flood hazards where base flood elevation
data have been provided as set forth in subsection
15-4.2 (Basis for
Establishing the Areas of Special Flood Hazard) or in subsection
15-6.2d,
the following standards are required:
a. Residential construction. New construction and substantial improvement
of any residential structure shall have the lowest floor, including
basement, elevated to or above base flood elevation.
b. Nonresidential construction. New construction or substantial improvement
of any commercial, industrial or other nonresidential structure shall
either have the lowest floor, including basement, elevated one foot
above the base flood elevation; or, together with attendant utility
and sanitary facilities, be floodproofed so that below the base flood
level the structure is watertight with walls substantially impermeable
to the passage of water and with structural components having the
capacity of resisting hydrostatic and hydrodynamic loads and effects
of buoyancy. A registered professional engineer or architect shall
certify that the standards of this paragraph are satisfied. Such certification
shall be provided to the Construction Code Official.
c. For all new construction and substantial improvements, fully enclosed
areas below the lowest floor that are subject to flooding shall be
designed to automatically equalize hydrostatic flood forces on exterior
walls by allowing for the entry and exit of floodwaters. Designs for
meeting this requirement must either be certified by a registered
professional engineer or architect or must meet or exceed the following
minimum criteria: A minimum of two openings having a total net area
of not less than one square inch for every square foot of enclosed
area subject to flooding shall be provided. The bottom of all openings
shall be no higher than one foot above grade. Openings may be equipped
with screens, louvers, or other covering or devices provided that
they permit the automatic entry and exit of floodwaters.
[Ord. No. 0-19-82 § 10C; Ord.
No. 0-12-88 § 7]
Located within areas of special flood hazard established in
subsection
15-4.2 are areas designated as floodways. Since the floodway
is an extremely hazardous area due to the velocity of floodwaters
which carry debris, potential projectiles and erosion potential, the
following provisions apply:
a. The prohibition of encroachments, including fill, new construction,
substantial improvements and other development unless a technical
evaluation demonstrates that encroachment shall not result in any
increase in flood levels during the occurrence of the base flood discharge.
b. If paragraph a. above is satisfied, all new construction and substantial
improvements shall comply with all applicable flood hazard reduction
provisions of this section.
c. In all areas of special flood hazard in which base flood elevation
data has been provided and no floodway has been designated, the cumulative
effect of any proposed development, when combined with all other existing
and anticipated development, shall not increase the water surface
elevation of the base flood more than 0.2 of a foot at any point.
d. Mobilehomes except within a mobilehome park or an existing mobilehome
subdivision are expressly prohibited.
The reference of bench names for this chapter as shown on the
Flood Boundary and Floodway Map, along with Insurance Rate Map, shall
