[HISTORY: Adopted by the Township Committee of the Township of Lumberton 8-1-1983 as Ord. No. 1983-8 (Ch. XVII of the 1973 Code). Amendments noted where applicable.]
The Legislature of the State of New Jersey has, in N.J.S.A. 40:48-1 et seq., or any amendments or supplements thereto, delegated the responsibility to local government units to adopt regulations designed to promote the public health, safety and general welfare of its citizenry. Therefore, the Township Committee of the Township of Lumberton, in the State of New Jersey, does ordain the following.
The flood hazard areas of the Township of Lumberton 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.
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.
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 and bridges located in areas of special flood hazard.
Help maintain a stable tax base by providing for the sound 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.
Ensure that those who occupy the areas of special flood hazard assume responsibility for their actions.
In order to accomplish its purposes, this chapter includes methods and provisions for:
Restricting or prohibiting uses which are dangerous to health, safety and property due to water or 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 floodwaters.
Controlling filling, grading, dredging and other development which may increase flood damage.
Preventing or regulating the construction of flood barriers which will unnaturally divert floodwaters or which may increase flood hazards in other areas.
Unless specifically defined below, words or phrases used in this chapter shall be interpreted so as to give them the meanings they have in common usage and to give this chapter its most reasonable application.
As used in this chapter, the following terms shall have the meanings indicated:
- A request for a review of the Building Inspector's interpretation of any provision of this chapter or a request for a variance.
- AREA OF SHALLOW FLOODING
- A designated AO Zone on the Flood Insurance Rate Map (FIRM). The base flood depths range from one to three feet; a clearly defined channel does not exist; the path of flooding is unpredictable and indeterminate; and velocity flow may be evident.
- AREA OF SPECIAL FLOOD HAZARD
- That 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.
- Any area of the building having its floor subgrade (below
ground level) on all sides.[Amended 3-16-1987 by Ord. No. 1987-5]
- 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.[Amended 3-16-1987 by Ord. No. 1987-5]
- 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 located within the area of special flood hazard.
- ELEVATED BUILDING
- A nonbasement building built, in the case of a building in an area of special flood hazard, to have the top of the elevated floor or, in the case of a building in a coastal high-hazard area, to have the bottom of the lowest horizontal structural member of the elevated floor elevated above the ground level by means of pilings, columns (posts and piers) or shear walls parallel to the flow of the water and adequately anchored so as not to impair the structural integrity of the building during a flood of 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 floodwaters. In areas of coastal high hazard, "elevated building" also includes a building otherwise meeting the definition of "elevated building," even though the lower area is enclosed by means of breakaway walls.
- FLOOD or FLOODING
- A general and temporary condition of partial or complete inundation of normally dry land areas from:
- FLOOD INSURANCE RATE MAP (FIRM)
- The official map on which the Federal Insurance Administration has delineated both the areas of special flood hazard and the risk premium zones applicable to the community.
- FLOOD INSURANCE STUDY
- The official report provided in which the Federal Insurance Administration has provided flood profiles, as well as the Flood Boundary - Floodway Map and the water surface elevation of the base flood.
- 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 of one foot.
- LOWEST FLOOR
- The lowest floor of the lowest enclosed area, including basement.
An unfinished or flood-resistant enclosure, usable 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

of other applicable nonelevation design requirements.[Amended 3-16-1987 by Ord. No. 1987-5]
- MANUFACTURED HOME
- A structure, transportable in one or more sections, which
is built on a permanent chassis and is designed for use with or without
a permanent foundation when connected to the required utilities. For
floodplain management purposes, the term "manufactured home" also
includes park trailers, travel trailers and other similar vehicles
placed on a site for greater than 180 consecutive days. For insurance
purposes, the term "manufactured home" does not include park trailers,
travel trailers and other similar vehicles.[Added 3-16-1987 by Ord. No. 1987-5]
- MANUFACTURED HOME PARK or MANUFACTURED HOME SUBDIVISION
- A parcel or contiguous parcels of land divided into two or
more manufactured home lots for rent or sale.[Added 3-16-1987 by Ord. No. 1987-5]
- NEW CONSTRUCTION
- Structures for which the start of construction commenced on or after the effective date of this chapter.
- REPETITIVE LOSS
- Flood-related damages sustained by a structure on two separate
occasions during a ten-year period for which the cost of repairs at

- START OF CONSTRUCTION
- For other than new construction or substantial improvements
under the Coastal Barrier Resources Act (P.L. 97-348), includes substantial
improvement and means the date the building permit was issued, provided
that the actual start of construction, repair, reconstruction, 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, 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.[Amended 3-16-1987 by Ord. No. 1987-5]
- A walled and roofed building, a manufactured home or a gas
or liquid storage tank that is principally above ground.[Amended 3-16-1987 by Ord. No. 1987-5]
- (1) Any combination of repairs, reconstruction, alteration, or improvements to a structure taking place during a ten-year period, in which the cumulative cost equals or exceeds 50% of the market value of the structure before the start of construction of the improvement. NOTE: The market value of the building should be the appraised value of the structure prior to the start of the initial repair or improvement, or in the case of damage, the value of the structure prior to the damage occurring. This term includes structures which have incurred repetitive loss or substantial damage, regardless of the actual amount of repair work performed. This term does not, however, include either:[Amended 7-10-2007 by Ord. No. 2007-12]
- (a) Any project for improvement of a structure to correct existing violations of state or local health, sanitary, or safety code specifications which has been identified by the local code enforcement official and which are the minimum necessary to assure safe living conditions; or
- (b) Any alteration of a historic structure, provided that the alteration will not preclude the structure’s continued designation as a historic structure.
- (2) For the purpose of this definition, “substantial improvement” is considered to occur when the first alteration of any wall, ceiling, floor, or other structural part of the structure commences, whether or not that alteration affects the external dimensions of the structure.
- A grant of relief from the requirements of this chapter which permits construction in a manner that would otherwise be prohibited by this chapter.
This chapter shall apply to all areas of special flood hazard within the jurisdiction of the Township of Lumberton.
The areas of special flood hazard identified by the Federal Emergency Insurance Administration in a scientific and engineering report entitled "Flood Insurance Study, Township of Lumberton," dated February 15, 1983, or any revision hereto, with accompanying Flood Insurance Rate Maps and Flood Boundary - Floodway Maps is hereby adopted by reference and declared to be a part of this chapter. The Flood Insurance Study is on file with the Township Clerk/Administrator at the Municipal Complex, Lumberton, New Jersey.
[Amended 8-3-1992 by Ord. No 1992-6]
No structure or land shall hereafter be constructed, located, extended, converted or altered without full compliance with the terms of this chapter and other applicable regulations. For violation of the provisions of this chapter by failure to comply with any of its requirements, including violations of conditions and safeguards established in connection with conditions, the maximum penalty, upon conviction, shall be a fine not exceeding $1,000 or imprisonment in the county jail for a term not exceeding 90 days or a period of community service not exceeding 90 days, or such combination of punishments as the Municipal Judge may, in his or her discretion, deem appropriate and just.
Separate violations. Each and every day in which a violation of any provision of this chapter exists shall constitute a separate violation.
Application. The maximum penalty stated in this section is not intended to state an appropriate penalty for each and every violation. Any lesser penalty, including a nominal penalty or no penalty at all, may be appropriate for a particular case or violation, except in those instances where state law mandates a minimum penalty to be imposed.
Minimum penalty. There shall be a minimum penalty of a fine fixed at an amount not exceeding $100.
Nothing herein contained shall prevent the Township of Lumberton from taking such other lawful action as is necessary to prevent or remedy any violation.
This chapter is not intended to repeal, abrogate or impair any existing easements, covenants or deed restrictions. However, where this chapter and any other ordinance, easement, covenant or deed restriction conflict or overlap, whichever imposes the more stringent restrictions shall prevail.
In the interpretation and application of this chapter, all provisions shall be:
The degree of flood protection required by this chapter is considered reasonable for regulatory purposes and is based on scientific and engineering considerations. Larger floods can and will occur on rare occasions. Flood heights may be increased by man-made or natural causes. This chapter does not imply that land outside the areas of special flood hazard or uses permitted within such areas will be free from flooding or flood damages. This chapter shall not create liability on the part of the Township of Lumberton, any officer or employee thereof or the Federal Insurance Administration for any flood damages that result from reliance on this chapter or any administrative decision lawfully made thereunder.
A development permit shall be obtained before construction or development begins within any area of special flood hazard established in § 157-7. Applications for a development permit shall be made on forms furnished by the Construction Official and may include, but not be limited to, plans in duplicate drawn to scale showing the nature, location, dimensions and elevations of the area in question, existing or proposed structures, fill, storage of materials, drainage facilities and the locations of the foregoing.
Specifically, the following information is required:
The elevation, in relation to mean sea level, of the lowest floor (including basement) of all structures.
The elevation, in relation to mean sea level, to which any structure has been floodproofed.
A certification by a registered professional engineer or architect that the floodproofing methods for any nonresidential structure meet the floodproofing criteria in § 157-18B.
A description of the extent to which any watercourse will be altered or relocated as a result of proposed development.
The Construction Official is hereby appointed to administer and implement this chapter by granting or denying development permit applications in accordance with its provisions.
Duties of the Construction Official shall include but not be limited to:
Permit review. The Construction Official shall:
Review all development permits to determine that the permit requirements of this chapter have been satisfied.
Review all development permits to determine that all necessary permits have been obtained from those federal, state or local government agencies from which prior approval is required.
Use of other base flood data. When base flood elevation and floodway data has not been provided in accordance with § 157-7, Basis for establishing areas of special flood hazard, the Construction Official shall obtain, review and reasonably utilize any base flood elevation and floodway data available from a federal, state or other source, in order to administer § 157-18, Specific standards, Subsection A, residential construction, and Subsection B, Nonresidential construction.
[Amended 3-16-1987 by Ord. No. 1987-5]
Information to be obtained and maintained. The Construction Official shall:
Obtain and record the actual elevation, in relation to mean sea level, of the lowest floor (including basement) of all new or substantially improved structures, and whether or not the structure contains a basement.
Alteration of watercourses. The Construction Official shall:
Notify adjacent communities and the Division of Water Resources prior to any alteration or relocation of a watercourse, and submit evidence of such notification to the Federal Insurance Administration.
Require that maintenance is provided within the altered or relocated portion of said watercourse so that the flood-carrying capacity is not diminished.
Interpretation of FIRM boundaries. The Construction Official shall make interpretations where needed, as to the exact location of the boundaries of the areas of special flood hazard (for example, where there appears to be a conflict between a mapped boundary and actual field conditions). The person contesting the location of the boundary shall be given a reasonable opportunity to appeal the interpretation as provided in § 157-15.
[Amended 1-20-2004 by Ord. No. 2004-1]
The Land Development Board, as established by the Township Committee, shall hear and decide appeals and requests for variances from the requirements of this chapter.
The Land Development 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 chapter.
Those aggrieved by the decision of the Land Development Board or any taxpayer may appeal such decision to the Superior Court.
In passing upon such applications, the Land Development 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 expected heights, velocity, duration, rate of rise and sediment transport of the floodwaters and the effects of wave action, if applicable, expected at the site.
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 Subsection D above and the purposes of this chapter, the Land Development Board may attach such condition to the granting of variances as it deems necessary to further the purposes of this chapter.
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.
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, provided that the items in § 157-15D(1) through (11) 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 reconstruction, rehabilitation or restoration of structures listed on the National Register of Historic Places or the State Inventory of Historic Places, without regard to the procedures set forth in the remainder of this section.
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 or extraordinary public expense or create nuisances, cause fraud on or victimization of the public, as identified in § 157-15D, 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.
In all areas of special flood hazard, 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. Methods of anchoring may include but are not to be limited to use of over-the-top or frame ties to ground anchors. This requirement is in addition to applicable state and local anchoring requirements for resisting wind forces.
[Amended 3-16-1987 by Ord. No. 1987-5]
Construction materials and methods.
All new and replacement water supply systems shall be designed to minimize or eliminate infiltration of floodwaters into the system.
New and replacement sanitary sewer systems shall be designed to minimize or eliminate infiltration of floodwaters into the systems and discharge from the systems into floodwaters.
On-site waste disposal systems shall be located to avoid impairment to them or contamination from them during flooding.
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.
[Added 3-16-1987 by Ord. No. 1987-5]
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.
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. For all new construction and substantial improvements, fully enclosed areas below the lowest floor that 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 coverings or devices, provided that they permit the automatic entry and exit of floodwaters.
[Added 3-16-1987 by Ord. No. 1987-5]
In all areas of special flood hazard where base flood elevation data have been provided as set forth in § 157-7, Basis for establishing areas of special flood hazard, or in § 157-14B, Use of other base flood data, the following standards are required:
Residential construction. New construction and substantial improvement of any residential structure shall have the lowest floor, including basement, elevated to or above base flood elevation.
Nonresidential construction. New construction and substantial improvement of any commercial, industrial or other nonresidential structure shall either have the lowest floor, including basement, elevated to the level of the base flood elevation or, together with attendant utility and sanitary facilities, shall:
Be floodproofed so that below the base flood level the structure is watertight with walls substantially impermeable to the passage of water,
Have structural components capable of resisting hydrostatic and hydrodynamic loads and effects of buoyancy; and
Be certified by a registered professional engineer or architect that the design and methods of construction are in accordance with accepted standards of practice for meeting any applicable provisions of this subsection. Such certification shall be provided to the official as set forth in § 157-14C(2).
[Amended 3-16-1987 by Ord. No. 1987-5]
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.
Federal floodplain standards. In addition to the standards referred to in this section or anywhere else in this chapter, all of the standards of Section 60.3(d) of the National Flood Insurance Program (44 CFR 59 et seq.) are hereby adopted by reference and made a part hereof. Also incorporated by reference and intended for the guidance of all interested agencies within the township is the final flood elevation determination by the Federal Emergency Management Agency made pursuant to Title 44, Chapter 1, Part 67, Code of Federal Regulations, and the Flood Insurance Rate Map issued by the Federal Emergency Management Agency and as periodically revised.
[Added 2-4-1991 by Ord. No. 1991-1]
Located within areas of special flood hazard established in § 157-7 are areas designated as floodways. Since the floodway is an extremely hazardous area due to the velocity of floodwaters which carry debris, potential projectiles and erosion potential, the following provisions apply:
Encroachments are prohibited, including fill, new construction, substantial improvements and other development, unless a technical evaluation demonstrates that encroachments shall not result in any increase in flood levels during the occurrence of the base flood discharge.
The placement of any manufactured homes is prohibited, except in an existing manufactured home park or existing home subdivision.
[Amended 3-16-1987 by Ord. No. 1987-5]
[Added 8-19-2014 by Ord. No. 2014-6-003]
The Township Committee hereby orders that all residents which need to mitigate properties within the Township floodplain must adhere to the following criteria when mitigating their properties:
[Added 8-19-2014 by Ord. No. 2014-6-003]
Residences considered having suffered severe repetitive loss and which have been declared substantially damaged need to be mitigated. During the process of mitigating their respective properties residents will receive a temporary certificate of occupancy which will expire on a date specified by the Township Construction Official. During this time period a resident's home must be mitigated to prevent from future loss. If a property is not mitigated within the allotted time frame a resident may petition the Township for an extension provided he/she has taken the steps to move forward in the mitigation process. At no point in time is the Township financially responsible for the mitigation of private property located in the floodplain.
