[Ord. #17-16 § 1]
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 City Council of the
City of Ocean City of Cape May County, New Jersey does ordain as follows.
[Ord. #17-16 § 1]
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 sound 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.
[Ord. #17-16 § 1]
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 help accommodate or channel
flood waters;
d. Controlling filling, grading, dredging, and other development which
may increase flood damage; and,
e. Preventing or regulating the construction of flood barriers which
will unnaturally divert flood waters or which may increase flood hazards
in other areas.

an area of special flood hazard shall:
(a)
Be consistent with the need to minimize flood damage,
(b)
Be constructed to minimize flood damage,
(c)
Have adequate drainage provided to reduce exposure to flood
damage; and,
(d)
Be elevated on a permanent foundation such that the top of the
lowest floor is at or above the best available flood hazard data elevation
plus two (2') feet or as required by ASCE/SEI 24-14, Table 2-1,
whichever is more restrictive; and,
(e)
The manufactured home chassis is supported by reinforced piers
or other foundation elements of at least equivalent strength that
are no less than thirty-six (36") inches in height above grade and
be securely anchored to an adequately anchored foundation system to
resist flotation, collapse and lateral movement.
[Ord. #17-16 § 1]
Coastal High Hazard Areas (V or VE Zones) and Coastal A Zones are located within the areas of special flood hazard established in subsection
21-3.2. 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 subdivision.
b. Construction Methods.
1. Elevation. All new construction and substantial improvements shall
be elevated on piling or columns so that:
(a)
The bottom of the lowest horizontal structural member of the
lowest floor (excluding the piling or columns) is elevated to or above
the best available flood hazard data elevation plus two feet, or as
required by ASCE/SEI 24-14, Table 4-1, whichever is more restrictive;
and
[Amended 11-26-2019 by Ord. No. 19-22]
(b)
All electrical, heating, ventilating, air-conditioning, mechanical
equipment and other equipment servicing the building is elevated two
feet above base flood elevation; and
[Amended 11-26-2019 by Ord. No. 19-22]
(c)
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 or in subsection
21-5.3b,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 (1%) percent chance of being equaled or exceeded
in any given year (100-year mean recurrence interval).
(c)
Prohibit the use of fill for structural support of buildings
within Zones V1-30, VE, V, and Coastal A on the community's FIRM.
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 subsections
21-5.3b,1 and 21-5.3b.2(a)—(b).
4. Space Below the Lowest Floor.
(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 lattice-work
or insect screening are used as provided for in this section.
(b)
Breakaway walls, open wood lattice-work or insect screening
shall be allowed below the design flood elevation (DFE) provided that
they are 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 ten (10) and no more than twenty (20) pounds per square foot.
Use of breakaway walls which exceed a design safe loading of twenty
(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.
[Amended 11-26-2019 by Ord. No. 19-22]
(1)
Breakaway wall collapse shall result from a water load less
than that which would occur during the base flood and,
(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 non-structural). Water
loading values used shall be those associated with the base flood.
Wind loading values 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 Construction Code Official or Building Subcode Official
for review.
[Amended 11-26-2019 by Ord. No. 19-22]
c. Sand Dunes. Prohibit man-made alteration of sand dunes within Coastal
A Zones, VE and V Zones on the community's DFIRM which would
increase potential flood damage.
