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 Andover Township, New Jersey, does ordain as follows.
The flood hazard areas of the Township of Andover 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 hazards 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.
A designated AO, AH or VO Zone on a community's Digital Flood Insurance Rate Map (DFIRM) with a one-percent-or-greater annual chance of flooding to an average depth of one foot 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.
Any area of the building having its floor surface subgrade (below ground level) on all sides.
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 elevated above the ground level by means of piling, 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 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.
The official report provided 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.
A vehicle which is built on a single chassis; is 400 square feet or less when measured at the longest horizontal projections; is designed to be self-propelled or permanently towable by a light-duty truck; and is designed primarily not for use as a permanent dwelling but as temporary living quarters for recreational, camping, travel or seasonal use.
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 aboveground.
Damage of any origin sustained by a structure whereby the cost of restoring the structure to its before-damage condition would equal or exceed 50% of the market value of the structure before the damage occurred.
This chapter shall apply to all areas of special flood hazards within the jurisdiction of the Township of Andover.
A scientific and engineering report "Flood Insurance Study, Sussex County New Jersey, (All Jurisdictions)," dated September 29, 2011.
Flood Insurance Rate Map for Sussex County, New Jersey (All Jurisdictions), as shown on Index and Panel Nos. 34037C0292E, 34037C0293E, 34037C0294E, 34037C0303E, 34037C0304E, 34037C0311E, 34037C0315E, 34037C0316E, 34037C0318E, 34037C0382E, 34037C0401E, 34037C0402E; the effective date of which is September 29, 2011.
The above documents are hereby adopted and declared to be a part of this chapter. The Flood Insurance Study and maps are on file at 134 Newton-Sparta Road, Newton, 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 fails to comply with any of its requirements shall, upon conviction thereof, be fined not more than $2,000 or imprisoned for 90 days, or both, for each violation, and in addition shall pay all costs and expenses involved in the case. Nothing herein contained shall prevent the Township of Andover 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 other ordinance, easement, covenant, or deed restrictions conflict or overlap, whichever imposed the more stringent restrictions shall prevail.
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 area 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 Township of Andover, 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 § 55-17B(2).
Review all development permits to determine if the proposed development is located in the floodway. If located in the floodway, assure that the encroachment provisions of § 55-18B are met.
Use of other base flood and floodway data. When base flood elevation and floodway data has not been provided in accordance with § 55-7, Basis for establishing areas of special flood hazard, the local administrator 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 § 55-17, Specific standards.
Maintain the floodproofing certifications required in § 55-12B(3).
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 hazards (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 § 55-15.
The Planning Board as established by Andover Township Committee shall hear and decide appeals and requests for variances from the requirements of this chapter.
The Planning 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 Planning Board, or any taxpayer, may appeal such decision to the Superior Court, as provided in N.J.S.A. 40:55D-17.
Upon consideration of the factors of Subsection A(4) above, and the purposes of this chapter, the Planning Board may attach such conditions to the granting of variances as it deems necessary to further the purposes of this chapter.
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 items in Subsection A(4)(a) through (k) above have been fully considered. As the lot size increases beyond 1/2 acre, the technical justification required for issuing the variance increases.
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 A(4) above, or conflict with existing local laws or ordinances.
Anchoring generally. All new construction and substantial improvements shall be anchored to prevent flotation, collapse, or lateral movement of the structure.
Anchoring of manufactured homes. 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.
For all new construction and substantial improvements, 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.
New construction and substantial improvement of any residential structure shall have the lowest floor, including basement together with the attendant utilities and sanitary facilities, elevated to or above base flood elevation.
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); and, require adequate drainage paths around structures on slopes to guide floodwaters around and away from proposed structures.
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 official as set forth in § 55-14C.
Manufactured homes shall be anchored in accordance with § 55-16A.
Located within areas of special flood hazard established in § 55-7 are areas designated as floodways.
Prohibit encroachments, 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.
If Subsection B(1) is satisfied, all new construction and substantial improvements shall comply with all applicable flood hazard reduction provisions of § 55-16, Provisions for flood hazard reduction, and § 55-17, Specific standards.
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 2/10 of a foot at any point.
