[Ord. No. 13-2006 § 1.1]
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.
[Ord. No. 13-2006 § 1.2]
The flood hazard areas of the Borough of South Toms River 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.
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, damage uses in other areas. Uses that are inadequately floodproofed, elevated or otherwise protected from flood damage also contribute to the flood loss.
[Ord. No. 13-2006 § 1.3]
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 protect human life and health;
To minimize expenditure of public money for costly flood control projects;
To minimize the need for rescue and relief efforts associated with flooding and generally undertaken at the expense of the general public;
To minimize prolonged business interruptions;
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;
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;
To insure that potential buyers are notified that property is in an area of special flood hazard; and
To ensure that those who occupy the areas of special flood hazard assume responsibility for their actions.
[Ord. No. 13-2006 § 1.4]
In order to accomplish its purposes, this ordinance includes methods and provisions for:
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;
Requiring that uses vulnerable to floods including facilities which serve such uses, be protected against flood damage at the time of initial construction;
Controlling the alteration of natural floodplains, stream channels, and natural protective barriers, which help accommodate or channel flood waters;
Controlling filling, grading, dredging, and other development which may increase flood damage; and,
Preventing or regulating the construction of flood barriers which will unnaturally divert flood waters or which may increase flood hazards in other areas.

Interpretation of FIRM Boundaries. Make interpretations where needed, as to the exact location of the boundaries of the areas of special flood hazards (for example, where there appears to be a conflict between a mapped boundary and actual filed conditions). The person contesting the location of the boundary shall be given a reasonable opportunity to appeal the interpretation as provided in subsection 19-4.4.
[Ord. No. 13-2006 §§ 4.4-1 — 4.4-2]
The Planning and Land Use Board as established by South Toms River shall hear and decide appeals and requests for variances from the requirements of this chapter.
The Planning and Land Use Board shall hear and decide appeals when it is alleged there is an error in any requirement, decision, or determination made by the Zoning Officer in the enforcement or administration of this chapter.
Those aggrieved by the decision of the Planning Board, or any taxpayer, may appeal such decision to the Superior Court of New Jersey.
In passing upon such applications, the Planning Board shall consider all technical evaluations, all relevant factors, standards specified in other sections of this chapter, and:
The danger that materials may be swept onto other lands to the injury of others;
The danger to life and property due to flooding or erosion damage;
The susceptibility of the proposed facility and its contents to flood damage and the effect of such damage on the individual owner;
The importance of the services provided by the proposed facility to the community;
The necessity to the facility of a waterfront location, where applicable;
The availability of alternative locations for the proposed use which are not subject to flooding or erosion damage;
The compatibility of the proposed use with existing and anticipated development;
The relationship of the proposed use to the Comprehensive Plan and floodplain management program of that area;
The safety of access to the property in times of flood for ordinary and emergency vehicles;

The costs of providing governmental services during and after flood conditions, including maintenance and repair of public utilities and facilities such as sewer, gas, electrical, and water systems, and streets and bridges.
Upon consideration of the factors of paragraph a.,4 of subsection 19-4.4, and the purposes of this chapter, the (appeal board) may attach such conditions to the granting of variances as it deems necessary to further the purposes of this chapter.
The Zoning Officer shall maintain the records of all appeal actions, including technical information, and report any variances to the Federal Insurance Administration upon request.
Conditions for Variances.
Generally, variances may be issued for new construction and substantial improvements to be erected on a lot of 1/2 acre or less in size contiguous to and surrounded by lots with existing structures constructed below the base flood level, providing the items in paragraph a.,4 above have been fully considered. As the lot size increases beyond the 1/2 acre, the technical justification required for issuing the variance increases.
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.
Variances shall not be issued within any designated floodway if any increase in flood levels during the base flood discharge would result.
Variances shall only be issued upon a determination that the variance is the minimum necessary, considering the flood hazard, to afford relief.
Variances shall only be issued upon:
A showing of good and sufficient cause;
A determination that failure to grant the variance would result in exceptional hardship to the applicant; and,
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 19-4.4a.,4, or conflict with existing local laws or ordinances.
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.
[Ord. No. 13-2006 § 5.1]
In all areas of special flood hazards the following standards are required:
All new construction and substantial improvements shall be anchored to prevent flotation, collapse, or lateral movement of the structure.
All manufactured homes shall be anchored to resist flotation, collapse or lateral movement.

Electrical, heating, ventilation, plumbing and air-conditioning equipment and other service facilities shall be designed and/or located so as to prevent water from entering or accumulating within the components during conditions of flooding.
All subdivision proposals shall be consistent with the need to minimize flood damage;
All subdivision proposals shall have public utilities and facilities such as sewer, gas, electrical, and water systems located and constructed to minimize flood damage;
All subdivision proposals shall have adequate drainage provided to reduce exposure to flood damage; and,
Base flood elevation data shall be provided for subdivision proposals and other proposed development which contain at least 50 lots or five acres (whichever is less).
Enclosure Openings. All new construction and substantial improvements having fully enclosed areas below the lowest floor that are usable solely for parking of vehicles, building access or storage in an area other than a basement and which are subject to flooding shall be designed to automatically equalize hydrostatic flood forces on exterior walls by allowing for the entry and exit of floodwaters. Designs for meeting this requirement must either be certified by a registered professional engineer or architect or must meet or exceed the following minimum criteria: A minimum of two openings having a total net area of not less than one square inch for every square foot of enclosed area subject to flooding shall be provided. The bottom of all openings shall be no higher than one foot above grade. Openings may be equipped with screens, louvers, or other covering or devices provided that they permit the automatic entry and exit of floodwaters.
[Ord. No. 2006-13 § 5.2]
In all areas of special flood hazards where base flood elevation data have been provided as set forth in subsection 3.2, Basis for Establishing the Areas of Special Flood Hazard or in subsection 19-4.3b, Use of Other Base Flood Data, the following standards are required:
In Zones Al-30 or AE zones new construction and substantial improvement of any residential structure shall have the lowest floor, including basement, elevated to or above base flood elevation;
Require within any AO zone on the municipality's FIRM that all new construction and substantial improvement of any residential structure shall have the lowest floor, including basement, elevated above the highest adjacent grade at least as high as the depth number specified in feet (at least two feet if no depth number is specified).

Manufactured homes shall be anchored in accordance with subsection 19-5.1a.,2.
All manufactured homes to be placed or substantially improved within an area of special flood hazard shall be elevated on a permanent foundation such that the top of the lowest floor is at or above the base flood elevation.
[Ord. No. 2006-13 § 5.3]
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:
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.
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.
