[Editor's Note: Prior ordinance history includes portions of Ordinance Nos. 1203 and 1314.]
[Ord. No. 09-38]
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 Township Committee of the Township of Neptune, County of Monmouth, New Jersey does ordain as follows.
[Ord. No. 09-38]
a. 
The flood hazard areas of the Township of Neptune are subject to periodic inundation which results in loss of life and property, health and safety hazards, disruption of commerce and governmental services, extraordinary public expenditures for flood protection and relief, and impairment of the tax base, all of which adversely affect the public health, safety, and general welfare.
b. 
These flood losses are caused by the cumulative effect of obstructions in areas of special flood hazard which increase flood heights and velocities, and when inadequately anchored, causes damage in other areas. Uses that are inadequately floodproofed, elevated or otherwise protected from flood damage also contribute to the flood loss.
[Ord. No. 09-38]
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:
a. 
To protect human life and health;
b. 
To minimize expenditure of public money for costly flood control projects;
c. 
To minimize the need for rescue and relief efforts associated with flooding and generally undertaken at the expense of the general public;
d. 
To minimize prolonged business interruptions;
e. 
To 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. 
To 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. 
To ensure that potential 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. 09-38]
In order to accomplish its purposes, this ordinance 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 floodwaters;
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 floodwaters or which may increase flood hazards in other areas.

Conditions for Variances.
1. 
Generally, variances may be issued for new construction and substantial improvements to be erected on a lot of one-half (1/2) acre or less in size contiguous to and surrounded by lots with existing structures constructed below the base flood level, providing items (a)—(k) in subsection 19-4.4a4 have been fully considered. As the lot size increases beyond the one-half (1/2) acre, the technical justification required for issuing the variance increases.
2. 
Variances may be issued for the repair or rehabilitation of historic structures upon a determination that the proposed repair or rehabilitation will not preclude the structure's continued designation as a historic structure and the variance is the minimum necessary to preserve the historic character and design of the structure.
3. 
Variances shall not be issued within any designated floodway if any increase in flood levels during the base flood discharge would result.
4. 
Variances shall only be issued upon a determination that the variance is the minimum necessary, considering the flood hazard, to afford relief.
5. 
Variances shall only be issued upon:
(a) 
A showing of good and sufficient cause;
(b) 
A determination that failure to grant the variance would result in exceptional hardship to the applicant; and
(c) 
A determination that the granting of a variance will not result in increased flood heights, additional threats to public safety, extraordinary public expense, create nuisances, cause fraud on or victimization of the public as identified in subsection 19-4.4a4, or conflict with existing local laws or ordinances.
6. 
Any applicant to whom a variance is granted shall be given written notice that the structure will be permitted to be built with a lowest floor elevation below the base flood elevation and that the cost of flood insurance will be commensurate with the increased risk resulting from the reduced lowest floor elevation.

Any decision of the HPC may be appealed to the Zoning Board of Adjustment in the manner set forth in § 706 (Appeals and Application to ZBOA) of the Land Development Ordinance.
[Ord. No. 09-38]
Located within areas of special flood hazard established in subsection 19-3.2 are areas designated as floodways. Since the floodway is an extremely hazardous area due to the velocity of flood waters 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 subsection 19-5.3a is satisfied, all new construction and substantial improvements must comply with Section 19-5, Provisions for Flood Hazard Protection.
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 two-tenths (0.2') of a foot at any point.
[Ord. No. 09-38; Ord. No. 13-12]
Coastal high hazard areas (V or VE Zones) are located within the areas of special flood hazard established in subsection 19-3.2. 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 manufactured home division.
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 (excluding piling or columns) is elevated to or above the base flood elevation, Advisory Base Flood Elevation or as required by the Uniform Construction Code (N.J.A.C. 5:23), whichever is more restrictive; and
(b) 
With all space below the lowest floor's supporting member so as not to impede with the flow of water, except for breakaway walls as provided for in subsection 19-5.4b4.
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) 
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 19-5.4b1 and 5.4b2(a) and (b).
4. 
Space Below the Lowest Floor.
(a) 
Any alteration, repair, reconstruction or improvement to a structure started after the enactment of this subsection 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 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 ten (10) and no more than 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.
(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 Building Subcode Official for approval.
c. 
Sand Dunes. Man-made alteration of sand dunes within Zones VE and V on the community's DFIRM which would increase potential flood damage is prohibited.
[Ord. No. 09-38]
The Construction Official shall receive from the applicant, along with the application, along with the application for a permit hereunder, a fee for the review of the application and the determination thereof. The fee shall be one hundred ($100.00) dollars for new construction and fifty ($50.00) dollars for additions.
[Ord. No. 09-38]
If this special use permit shall be issued, the Construction Official or his designee, Subcode Official, with the assistance of the Township Engineer, shall make an on-site inspection, at least once during construction, to determine whether the construction conforms to the approved plan, materials and other specifications provided by the applicant.
[Ord. No. 09-38]
In areas that the Federal Insurance Administrator has designated an area within the floodplain as having special flood hazards, such designation concerning land use control designed to reduce flood loss shall take precedence over any conflicting ordinances or codes of the Township.
[Ord. No. 09-38]
The grant of the special use permit or approval of a subdivision plan within the special flood hazard areas shall not constitute a representation, guaranty or warranty of any kind by the Township or by any official or employee thereof of the practicability or safety of the proposed use and shall create no liability upon the Township, its officers or employees.
[Ord. No. 09-38]
All previous ordinances or resolutions or portions thereof of the Township of Neptune inconsistent herewith be and they are hereby repealed.
[Ord. No. 09-38]
If any clause, section or provision of this chapter is declared invalid by a Court of competent jurisdiction, such provision shall be deemed a separate, distinct and independent provision and shall not affect the validity of the remaining portion hereof.
[Ord. No. 09-38]
This chapter shall take effect upon adoption and publication in accordance with law.
