Title XII, Flood Damage Prevention, was amended in entirety 3-24-2020 by Ord. No. 6PSF-A, 03-24-2020. Prior history includes Ord. No. 6S+FA(S-1), 6-1-2007. Amendments noted where applicable.
[Amended 3-24-2020 by Ord. No. 6PSF-A, 03-24-2020]
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) (together with the attendant utilities and sanitary facilities as well as all electrical, heating, ventilating, air-conditioning and other service equipment) is elevated to or above the more restrictive:
1. 
Base flood elevation (published FIS/FIRM) plus one foot;
2. 
The best available flood hazard data elevation plus one foot;
3. 
As required by ASCE/SEI 24-14, Table 2-1; or
4. 
As required by N.J.A.C. 7:13-3.
b. 
Record the method and elevation used above and, the Best Available Flood Hazard Design Data elevation, date and revision in the local Development Permit; and
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 Section 12:5-4.
[Amended 3-24-2020 by Ord. No. 6PSF-A, 03-24-2020]
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 1% 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.
[Amended 3-24-2020 by Ord. No. 6PSF-A, 03-24-2020]
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 Sections 12:5-1 and 12:5-2a and b.
[Amended 3-24-2020 by Ord. No. 6PSF-A, 03-24-2020]
a. 
Any alteration, repair, reconstruction or improvement to a structure started after the enactment of this Title 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 base flood elevation 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 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; 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 approval.
[Amended 3-24-2020 by Ord. No. 6PSF-A, 03-24-2020]
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.
