The Legislature of the State of New Jersey has, in N.J.S.A.
40:48-1 et seq., delegated the responsibility to local governmental
units to adopt regulations designed to promote public health, safety,
and general welfare of its citizenry. Therefore, the Mayor and Council
of the Township of Brick, of Ocean County, New Jersey, does ordain
as follows.
It is the purpose of this chapter to promote the public health,
safety, and general welfare, and to minimize public and private losses
due to flood conditions in specific areas by provisions designed to:
A. Protect human life and health;
B. Minimize expenditure of public money for costly flood control projects;
C. Minimize the need for rescue and relief efforts associated with flooding
and generally undertaken at the expense of the general public;
D. Minimize prolonged business interruptions;
E. Minimize damage to public facilities and utilities such as water
and gas mains, electric, telephone and sewer lines, streets, bridges
located in areas of special flood hazard;
F. Help maintain a stable tax base by providing for the second use and
development of areas of special flood hazard so as to minimize future
flood blight areas;
G. Ensure that potential buyers are notified that property is in an
area of special flood hazard; and
H. Ensure that those who occupy the areas of special flood hazard assume
responsibility for their actions.
In order to accomplish its purposes, this chapter uses the following
methods:
A. Restrict or prohibits 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. Require that uses vulnerable to floods including facilities which
serve such uses, be protected against flood damage at the time of
initial construction;
C. Control the alteration of natural floodplains, stream channels, and
natural protective barriers, which help accommodate or channel floodwaters;
D. Control filling, grading, dredging, and other development which may
increase flood damage; and,
E. Prevent and regulates the construction of flood barriers which will
unnaturally divert floodwaters or which may increase flood hazards
in other areas.
Unless specifically defined below, words or phrases used in
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.

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 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 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 above the ground.

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."
THIRTY-YEAR SETBACK
A distance equal to 30 times the average annual long-term
recession rate at a site, measured from the reference feature.

two feet if no depth number is specified) or at or above the best
available flood hazard data, whichever is more restrictive; plus one
foot of freeboard and require adequate drainage paths around structures
on slopes to guide floodwaters around and away from proposed structures;
(2) Or:
(a)
Be floodproofed so that below the base flood level or best available
flood hazard data (whichever is more restrictive) plus one foot of
freeboard the structure is watertight with walls substantially impermeable
to the passage of water;
(b)

homes newly constructed, substantially improved and/or reconstructed
due to substantial damage.
Located within areas of special flood hazard established in §
196-7 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. Prohibit 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 §
196-19A is satisfied, all new construction and substantial improvements must comply with §
196-17, Provisions for flood hazard reduction.
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.
Coastal high hazard areas (V or VE Zones) are located within the areas of special flood hazard established in §
196-7. These areas have special flood hazards associated with high-velocity waters from tidal surges and hurricane wave wash; therefore, the following provisions shall apply:
A. Location of structures.
(1) All buildings or structures shall be located landward of the reach
of the mean high tide.
(2) The placement of manufactured homes shall be prohibited, except in
an existing manufactured home park or manufactured home subdivision,
or as specified below:
(a)
A manufactured home may be placed on a property where a structure
has been determined by the Municipal Engineer to be substantially
damaged.\
(b)
The manufactured home may receive a temporary certificate of
occupancy for a period not to exceed two years.
(c)
All additional requirements of the UCC and this chapter shall
be adhered to prior to the issuance of any certificate of occupancy.
B. Construction methods.
(1) Elevation. All new construction and substantial improvements shall be elevated on pilings or columns so that the bottom of the lowest horizontal structural member of the lowest floor, excluding the piling or columns, is elevated to or above the base flood level, with all space below the lowest floor's supporting member open so as not to impede the flow of water, except for breakaway walls as provided for in Subsection
B(4).
(2) Structural support.
(a)
All new construction and substantial improvements shall be securely
anchored on piling or columns.
(b)
The pile or column foundation and structure attached thereto
shall be anchored to resist flotation, collapse or lateral movement
due to the effects of wind and water loading values, each of which
shall have a one-percent chance of being equaled or exceeded in any
given year (one-hundred-year mean recurrence interval).
(c)
There shall be no fill used for structural support.
(3) Certification. A registered professional engineer or architect shall develop or review the structural design specifications and plans for the construction and shall certify that the design and methods of construction to be used are in accordance with accepted standards of practice for compliance with the provisions of Subsection
B(1) and
(2)(a) and
(b).
(4) Space below the lowest floor shall conform to the following requirements:
(a)
Any alteration, repair, reconstruction or improvement to a structure
started after the enactment of this chapter shall not enclose the
space below the lowest floor unless breakaway walls, open wood latticework
or insect screening is used as provided for in this section.
(b)
Breakaway walls, open wood latticework or insect screening shall
be allowed below the base flood elevation, provided that it is intended
to collapse under wind and water loads without causing collapse, displacement
or other structural damage to the elevated portion of the building
or supporting foundation system. Breakaway walls shall be designed
for a safe loading resistance of not less than 10 and no more than
20 pounds per square foot. Use of breakaway walls which exceed a design
safe loading of 20 pounds per square foot (either by design or when
so required by local or state codes) may be permitted only if a registered
professional engineer or architect certifies that the designs proposed
meet the following conditions:
[1]
Breakaway wall collapse shall result from a water load less
than that which would occur during the base flood.
[2]
The elevated portion of the building and supporting foundation
system shall not be subject to collapse, displacement or other structural
damage due to the effects of wind and water load acting simultaneously
on all building components (structural and nonstructural). Water loading
valves used shall be those associated with the base flood. Wind loading
valves used shall be those required by applicable state or local building
standards.
(c)
If breakaway walls are utilized, such enclosed space shall be
used solely for parking of vehicles, building access or storage and
not for human habitation.
(d)
Prior to construction, plans for any breakaway wall must be
submitted to the local administrator for approval.
(e)
Solid breakaway walls are prohibited in the coastal high-hazard
area.
C. Sand dunes. There shall be no alteration of sand dunes that would
increase potential flood damage.
All requests for certification regarding the Flood Hazard Boundary
Map or the Flood Insurance Rate Map of the Township of Brick shall
be made to the Municipal Engineer of the Township of Brick.
All requests for certification concerning the above maps shall
be made, in writing, by the owner of the subject property or his authorized
agent and shall include an accurate description of the property sufficient
for the Municipal Engineer to determine the location of the subject
property on the applicable map.
There shall be a fee of $10 charged for each certification,
which fee shall accompany the request thereof.
