[HISTORY: Adopted by the Mayor and Council of the Borough of Edgewater 11-23-1982 by Ord. No. 735-82; amended in its entirety 10-16-1995 by Ord. No. 1062-95 (Ch. 153 of the 1975 Code). Subsequent amendments noted where applicable.]
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 the public health, safety and general welfare of its citizenry. Therefore, the governing body of the Borough of Edgewater of the State of New Jersey does ordain as follows:
The flood hazard areas of the Borough of Edgewater 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; and
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 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 floodwaters;
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 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 Construction Official's interpretation of any provision of this chapter or a request for a variance.
- AREA OF SHALLOW FLOODING
- A designated AO, AH or VO Zone on a community's Flood Insurance Rate Map (FIRM), with a one-percent or greater annual 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.
- Any area of the building having its floor subgrade (below ground level) on all sides.
- BREAKAWAY WALL
- A wall that is 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.
- 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.
- ELEVATED BUILDING

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.
- 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 (FIS)
- The official report provided in which the Federal Insurance
Administration has provided flood profiles, as well as the Flood Insurance
Rate Map.[Amended 9-19-2005 by Ord. No. 1319-2005]
- 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.
- 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.

- 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 that such enclosure is not built so to render the structure in violation of other applicable nonelevation design requirements.
- 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 attached to the required utilities. The term "manufactured home" does not include a recreational vehicle.

- RECREATIONAL VEHICLE
- A vehicle which is built on a single chassis; 400 square feet or less when measured at the longest horizontal projections; designed to be self-propelled or permanently towable by a light-duty truck; and not designed primarily 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 that 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.
- A walled and roofed building, a manufactured home, or a gas or liquid storage tank that is principally above ground.

[Amended 9-19-2005 by Ord. No. 1319-2005]
This chapter shall apply to all areas of special flood hazards within the jurisdiction of the Borough of Edgewater. The areas of special flood hazard identified by the Federal Insurance Administration in a scientific and engineering report entitled "The Flood Insurance Study of Bergen County, New Jersey, with accompanying Flood Insurance Rate Map Panels 276, 277, 278, 279, and 286 of 332 dated September 30, 2005, is hereby adopted by reference and declared to be a part of this chapter. The Flood Insurance Study is on file at the Office of the Borough Clerk, Municipal Building of the Borough of Edgewater, 916 River Road, Edgewater, New Jersey.
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. 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) shall constitute a misdemeanor. Any person who violates this chapter or who fails to comply with any of its requirements shall, upon conviction thereof, be punishable as provided in Chapter 1, Article II, General Penalty, for each violation and in addition, shall pay all costs and expenses involved in the case. Nothing herein contained shall prevent the Borough of Edgewater 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 another chapter, 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 hazards 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 Borough of Edgewater, 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 § 210-5, Applicability, shall be made on forms furnished by the Construction Official and may include, but shall 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 location of the foregoing.
The following information shall be required for a development permit:
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;
Certification by a registered professional engineer or architect that the floodproofing methods for any nonresidential structure meet the floodproofing criteria in § 210-19, Specific standards, and of this chapter; and
A description of the extent to which any watercourse will be altered or relocated as a result of the 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.
The duties of the Construction Official shall include, but not be limited to, the following:
Review of all development permits to determine that the permit requirements of this chapter have been satisfied.
Review of all development permits to determine that all necessary permits have been obtained from those federal, state or local governmental agencies from which prior approval is required.
Review of all development permits to determine if the proposed development is located in the floodway and to assure that the encroachment-provisions of this chapter are met, as well as to determine if the proposed development adversely affects the flood-carrying capacity of the area of special flood hazard. For the purposes of this chapter, "adversely affects" means damage to adjacent properties because of rises in flood stages attributed to physical changes of the channel and the adjacent overbank areas.
When base flood elevation and floodway data has not been provided in accordance with § 210-5, 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 § 210-19, Specific standards.
In considering an application for a development permit, the Construction Official shall:
Obtain and record the actual elevation in relation to mean sea level, of the lowest floor, including the basement, of all new or substantially improved structures and whether or not the structure contains a basement.
Maintain for public inspection all records pertaining to the provisions of this chapter.
If an application for a development permit involves the alteration or relocation of a watercourse, the Construction Official shall:
Notify adjacent communities and the appropriate state agency prior to any alteration or relocation of a watercourse and submit evidence of such notification to the Federal Insurance Administration.
Require that maintenance provided within the altered or relocated portion of said watercourse so that the flood-carrying capacity is not diminished.
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 § 210-16, Appeals.
The Board of Adjustment, as established by the Borough of Edgewater, shall hear and decide appeals and requests for variances from the requirements of this chapter.
The Board of Adjustment 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 Board of Adjustment, or any taxpayer, may appeal such decision to the Mayor and Council of the Borough of Edgewater, pursuant to § 240-28 of the Land Use Procedures Ordinance of the Borough of Edgewater; provided, however, that such appeal is taken in accordance with the provisions set forth in N.J.S.A. 40:55D-17.
In passing upon such applications, the Board of Adjustment 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; 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 set forth in Subsection D and the purposes of this chapter, the Board of Adjustment may attach such conditions 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 provisions of § 210-16D(1) through (11) 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 an 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, creation of nuisances or cause fraud on or victimization of the public as identified in § 210-16D or conflict with the existing local laws or chapters.
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 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. 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.
Construction materials and methods.
All new and replacement water supply systems shall be designed to minimize or eliminate infiltration of flood waters into the system.
New and replacement sanitary sewage 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.
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. For all new construction and substantial improvements, fully enclosed areas below the lowest floor that are usable solely for the 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.
In all areas of special flood hazards where base flood elevation data have been provided as set forth in § 210-5, Applicability, or in § 210-12, Use of other base flood and floodway 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
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 the applicable provisions of this subsection. Such certification shall be provided to the Construction Official as set forth in § 210-12B.
[Amended 9-19-2005 by Ord. No. 1319-2005]
Located within areas of special flood hazard established in § 210-5 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, shall not increase the water surface elevation of the base flood more than 0.2 of a foot at any point.
