Coastal high-hazard areas (V or VE Zones) and Coastal A Zones are located within the areas of special flood hazard established in Article IV. These areas have special flood hazards associated with high-velocity waters from tidal surges and hurricane wave wash. Flood hazard protection areas were also established in recognition of the challenges posed by erodible soils to foundations in these areas. Therefore, the following provisions shall apply:

All breakaway walls shall be constructed according to structural designs, plans and specifications conforming with ASCE 24 Chapter 4, signed by a licensed design professional, and certified by that individual in a breakaway wall certificate. Prior to construction, plans for breakaway walls must be submitted to the Code Enforcement Official for approval.

[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 nonstructural). 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.
(5) 
Enclosures. All new construction and substantial improvements with fully enclosed areas below the lowest floor shall be used solely for parking of vehicles, building access, or storage in an area other than a basement and which are subject to flooding. Enclosures shall:

(8) 
Structural support.
(a) 
All new construction and substantial improvements shall be elevated on piling or columns.
(b)

There shall be no fill used for any structural support in any V Zone.
[1] 
All pilings shall have a minimum diameter of 10 inches and shall be driven or jetted so that the lowest point of such pilings shall be 10 feet below sea level as determined by the 1988 North America Vertical Datum. If any such pilings are jetted, they must be driven to resistance.
[2] 
Any wood and pilings installed at grade or below designated flood elevations shall be appropriately pressure preserved to meet the standards of AWPA (American Wood-Preservers' Association) U1 for the species, product, preservative, and end use of the material. Plywood shall be preservative treated in accordance with AWPA (American Wood-Preservers' Association) standard C9-3 with creosote, pentachlorophenol preservatives, or equivalent.

Pursuant to N.J.A.C. 7:13, any fence located in a floodway shall have sufficiently large openings so as not to catch debris during a flood and thereby obstruct floodwaters, such as barbed-wire, split-rail, or strand fence. A fence with little or no open area, such as a chain link, lattice, or picket fence, does not meet this requirement. Foundations for fences greater than six feet in height must conform with the Uniform Construction Code. Fences for pool enclosures having openings not in conformance with this section but in conformance with the Uniform Construction Code to limit climbing require a variance as described in Article VII of this chapter.

A. 
In coastal high hazard areas (V Zones) and Coastal A Zones, development activities other than buildings and structures shall be permitted only when also authorized by the appropriate federal, state or local authority; when located outside the footprint of, and not structurally attached to, buildings and structures; and when analyses prepared by a licensed professional engineer demonstrates no harmful diversion of floodwater or wave runup and wave reflection that would increase damage to adjacent buildings and structures. Such other development activities include but are not limited to:
(1) 
Bulkheads, seawalls, retaining walls, revetments, and similar erosion control structures;
(2) 
Solid fences and privacy walls, and fences prone to trapping debris, unless designed and constructed to fail under flood conditions less than the base flood or otherwise function to avoid obstruction of floodwater; and
(3) 
On-site filled or mound sewage systems.
A. 
In coastal high hazard areas and Coastal A Zones:
(1) 
Minor grading and the placement of minor quantities of nonstructural fill shall be permitted for landscaping and for drainage purposes under and around buildings.
(2) 
Nonstructural fill with finished slopes that are steeper than one unit vertical to five units horizontal shall be permitted only when an analysis prepared by a licensed professional engineer demonstrates no harmful diversion of floodwater or wave runup and wave reflection that would increase damage to adjacent buildings and structures.
(3) 
Sand dune construction and restoration of sand dunes under or around elevated buildings are permitted without additional engineering analysis or certification of the diversion of floodwater or wave runup and wave reflection where the scale and location of the dune work is consistent with local beach-dune morphology and the vertical clearance is maintained between the top of the sand dune and the lowest horizontal structural member of the building.
