Ordinance No. 11-20
Introduced: August 22, 2011
Public Hearing: September 12, 2011
An ordinance to replace Chapter 275 of the code of the Township of Vernon regarding flood hazard insurance
BE IT ORDAINED by the Mayor and Council of the Township of Vernon as follows:
Section 1. The Code of the Township of Vernon is amended to replace Chapter 275 in its entirety as follows:
275-1 STATUTORY AUTHORIZATION, FINDINGS OF FACT, PURPOSE AND OBJECTIVES
275-1.1 STATUTORY AUTHORIZATION
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 Mayor and Township Council of the Township of Vernon in the County of Sussex, State of New Jersey does ordain as follows:
275-1.2 FINDINGS OF FACT
- The flood hazard areas of Township of Vernon 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, causes damage in other areas. Uses that are inadequately floodproofed, elevated or otherwise protected from flood damage also contribute to the flood loss.
275-1.3 STATEMENT OF PURPOSE
It is the purpose of this ordinance 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;
- Minimize expenditure of public money for costly flood control projects;
- Minimize the need for rescue and relief efforts associated with flooding and generally undertaken at the expense of the general public;
- Minimize prolonged business interruptions;
- 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;
- 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;
- Ensure that potential buyers are notified that property is in an area of special flood hazard; and
- Ensure that those who occupy the areas of special flood hazard assume responsibility for their actions.
275-1.4 METHODS OF REDUCING FLOOD LOSSES
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.
Unless specifically defined below, words or phrases used in this ordinance shall be interpreted so as to give them the meaning they have in common usage and to give this ordinance its most reasonable application.
Appeal—A request for a review of the Construction Official’s interpretation of any provision of this Ordinance or a request for a variance.
Area of Shallow Flooding—A designated AO, AH, or VO zone on a community’s Digital Flood Insurance Rate Map (DFIRM) with a one percent annual or greater chance of flooding to an average depth of one to three feet where a clearly defined channel does not exist, where the path of flooding is unpredictable and where velocity flow may be evident. Such flooding is characterized by ponding or sheet flow.
Area of Special Flood Hazard—The land in the floodplain within a community subject to a one percent or greater chance of flooding in any given year.
Base Flood—The flood having a one percent chance of being equaled or exceeded in any given year.
Basement—Any area of the building having its floor subgrade (below ground level) on all sides.
Breakaway Wall—A wall that is not part of the structural support of the building and is intended through its design and construction to collapse under specific lateral loading forces without causing damage to the elevated portion of the building or supporting foundation system.
Development—Any man made change to improved or unimproved real estate, including but not limited to buildings or other structures, mining, dredging, filling, grading, paving, excavation or drilling operations, or storage of equipment or materials located within the area of special flood hazard.
Digital Flood Insurance Rate Map (DFIRM)—The official map on which the Federal Insurance Administration has delineated both the areas of special flood hazards and the risk premium zones applicable to the community.
Elevated Building—A non-basement building (i) built in the case of a building in an Area of Special Flood Hazard to have the top of the elevated floor elevated above the ground level by means of piling, columns (posts and piers), or shear walls parallel to the flow of the water, and (ii) adequately anchored so as not to impair the structural integrity of the building during a flood up to the magnitude of the base flood. In an Area of Special Flood Hazard “elevated building” also includes a building elevated by means of fill or solid foundation perimeter walls with openings sufficient to facilitate the unimpeded movement of flood waters.
Flood or Flooding—A general and temporary condition of partial or complete inundation of normally dry land areas from:
- The overflow of inland or tidal waters and/or
- The unusual and rapid accumulation or runoff of surface waters from any source.
Flood Insurance Study (FIS)—The official report in which the Federal Insurance Administration has provided flood profiles, as well as the Flood Insurance Rate Map(s) and the water surface elevation of the base flood.
Flood Insurance Rate Map (FIRM)—The official map on which the Federal Insurance Administration has delineated both the areas of special flood hazards and the risk premium zones applicable to the community.
Floodplain Management Regulations—Zoning ordinances, subdivision regulations, building codes, health regulations, special purpose ordinances (such as a floodplain ordinance, grading ordinance and erosion control ordinance) and other applications of police power. The term describes such State or local regulations, in any combination thereof, which provide standards for the purpose of flood damage prevention and reduction.
Floodway—The channel of a river or other watercourse and the adjacent land areas that must be reserved in order to discharge the base flood without cumulatively increasing the water surface elevation more than 0.2 foot.
Highest Adjacent Grade—The highest natural elevation of the ground surface prior to construction next to the proposed walls of a structure.
Historic Structure—Any structure that is:
- Listed individually in the National Register of Historic Places (a listing maintained by the Department of Interior) or preliminarily determined by the Secretary of the Interior as meeting the requirements for individual listing on the National Register;
- Certified or preliminarily determined by the Secretary of the Interior as contributing to the historical significance of a registered historic district or a district preliminarily determined by the Secretary to qualify as a registered historic district;

- Individually listed on a local inventory of historic places in communities with historic preservation programs that have been certified either:
- By an approved State program as determined by the Secretary of the Interior; or
- Directly by the Secretary of the Interior in States without approved programs.
Lowest Floor—The lowest floor of the lowest enclosed area [including basement]. An unfinished or flood resistant enclosure, useable solely for the parking of vehicles, building access or storage in an area other than a basement is not considered a building’s lowest floor provided that such enclosure is not built so to render the structure in violation of other applicable non-elevation design requirements.
Manufactured Home—A structure, transportable in one or more sections, which is built on a permanent chassis 400 square foot or greater in area and is designed for use with or without a permanent foundation when attached to the required utilities.

New Manufactured Home Park or Subdivision—A manufactured home park or subdivision for which the construction of facilities for servicing the lots on which the manufactured homes are to be affixed (including at a minimum, the installation of utilities, the construction of streets, and either final site grading or the pouring of concrete pads) is completed on or after the effective date of the floodplain management regulations adopted by the municipality.
Park Model—A structure built on a single chassis which is over 320 square feet but less than 400 square feet or is over 8 feet in width.
Recreational Vehicle—A vehicle which is [i] built on a single chassis; [ii] 320 square feet or less and less than 8 feet in width when measured at the longest horizontal projections; [iii] designed to be self-propelled or permanently towable by a light duty truck; and [iv] designed primarily not for use as a permanent dwelling but as temporary living quarters for recreational, camping, travel, or seasonal use.
Start of Construction—For other than new construction or substantial improvements under the Coastal Barrier Resources Act (P.L. No. 97-348) includes substantial improvements and means the date the building permit was issued, provided the actual start of construction, repair, reconstruction, rehabilitation, addition, placement, or other improvement was within 180 days of the permit date. The actual start means either the first placement of permanent construction of a structure on a site such as the pouring of a slab or footings, the installation of piles, the construction of columns, or any work beyond the stage of excavation, or the placement of a manufactured home on a foundation.
Permanent construction does not include land preparation, such as clearing, grading and filling nor does it include the installation of streets and/or walkways, nor does it include excavation for a basement, footings or piers, or foundations or the erection of temporary forms, nor does it include the installation on the property of accessory buildings, such as garages or sheds not occupied as dwelling units or not part of the main structure. For a substantial improvement, the actual start of construction means the first alteration of any wall, ceiling, floor, or other structural part of a building, whether or not that alteration affects the external dimensions of the building.

Substantial Improvement—Any reconstruction, rehabilitation, addition, or other improvement of a structure, the cost of which exceeds 50 percent of the (market value) tax assessed value of the structure before the “start of construction” of the improvement. This term includes structures which have incurred “substantial damage”, regardless of the actual repair work performed. The term does not, however, include either:
- Any project for improvement of a structure to correct existing violations of State or local health, sanitary or safety code specifications which have been identified by the local code enforcement officer and which are the minimum necessary to assure safe living conditions; or
- Any alteration of a “historic structure”, provided that the alteration will not preclude the structure’s continued designation as a “historic structure”.
Training—Approved training programs recognized by FEMA for Certification.
Variance—A grant of relief from the requirements of this Ordinance that permits construction in a manner that would otherwise be prohibited by this Ordinance.

275-4.4 VARIANCE PROCEDURE
275-4.4-1 APPEAL BOARD
- The Land Use Board as established by the Township Council shall hear and decide appeals and requests for variances from the requirements of this Ordinance.
- The 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 Construction Official in the enforcement or administration of this Ordinance.
- Those aggrieved by the decision of the Land Use Board, or any taxpayer, may appeal such decision to the Superior Court of New Jersey.
- In passing upon such applications, the Land Use Board, shall consider all technical evaluations, all relevant factors, standards specified in other sections of this Ordinance, 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 expected heights, velocity, duration, rate of rise, and sediment transport of the flood waters and the effects of wave action, if applicable, expected at the site; and,
- 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 SECTION 275-4.4-1  and the purposes of this Ordinance, the Land Use board may attach such conditions to the granting of variances as it deems necessary to further the purposes of this Ordinance.
- The Construction Official shall maintain the records of all appeal actions, including technical information, and report any variances to the Federal Insurance Administration upon request.
275-4.4-2 CONDITIONS FOR VARIANCES
- Generally, variances may be issued for new construction and substantial improvements to be erected on a lot of one-half acre or less in size contiguous to and surrounded by lots with existing structures constructed below the base flood level, providing items (i-xi) in SECTION 275-4.4-1 have been fully considered. As the lot size increases beyond the one-half 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 SECTION 275-4.4-1, or conflict with existing local laws or ordinances.
- Any applicant to whom a variance is granted shall be given written notice via a resolution 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.
