In all areas of special flood hazard, the following provisions are required:

A. Anchoring.

(1) All new construction and substantial improvements shall be anchored to prevent flotation, collapse or lateral movement of the structure.

(2) All manufactured homes shall be anchored to resist flotation, collapse or lateral movement. Methods of anchoring may include, but are not 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.

B. Construction materials and methods.

(1) All new construction and substantial improvements shall be constructed with materials and utility equipment resistant to flood damage.

(2) All new construction and substantial improvements shall be constructed using methods and practices that minimize flood damage.

C. Utilities.

(1) All new and replacement water supply systems shall be designated to minimize or eliminate infiltration of floodwaters into the system.

(2) 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.

(3) On-site waste disposal systems shall be located to avoid impairment to them or contamination from them during flooding.

(4) 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.

D. Subdivision proposals.

(1) All subdivision proposals shall be consistent with the need to minimize flood damage.

(2) All subdivision proposals shall have public utilities and facilities, such as sewer, gas, electrical and water systems, located and constructed to minimize flood damage.

(3) All subdivision proposals shall have adequate drainage provided to reduce exposure to flood damage.

(4) 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.

E. Enclosure openings.

(1) 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.

(2) 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) 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.

(b) The bottom of all openings shall be no higher than one foot above grade.

(c) Openings may be equipped with screens, louvers or other coverings or devices, provided that they permit the automatic entry and exit of floodwaters.

In all areas of special flood hazard where base flood elevation data have been provided as set forth in § 102-111, Basis for establishing areas of special flood hazard, or in § 102-118B(2), Use of other base flood data, the following standards are required:

A. Residential construction. New construction and substantial improvement of any residential structure shall have the lowest floor, including the basement, elevated to or above base flood elevation.

B. 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:

(1) Be floodproofed so that below the base flood level the structure is watertight with walls substantially impermeable to the passage of water;

(2) Have structural components capable of resisting hydrostatic and hydrodynamic loads and effects of buoyancy; and

(3) 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.

C. Manufactured homes. 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.

Located within areas of special flood hazard established in § 102-111 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 shall apply:

A. Encroachments, including fill, new construction, substantial improvements and other development, shall be prohibited unless a technical evaluation demonstrates that encroachments shall not result in any increase in flood levels during the occurrence of the base flood discharge.

B. If Subsection A is satisfied, all new construction and substantial improvements shall comply with all applicable flood hazard reduction provisions of this article.

A. Construction or alteration prohibited. All land within the natural and ordinary high water mark, hereinafter referred to as the "record high water mark" or the "flood encroachment line," if no historical flood of record data is available, of any of the lakes, watercourses or water areas designated in § 102-111 of this Part 7 shall be considered a protected zone and designated as a water resource conservation area on the Zoning Map of the Township of Boonton. The following activities are prohibited within the water resource conservation areas:

(1) The alteration or construction of any building or structure of any kind, except as permitted under Subsection B.

(2) The removal of the natural vegetation, including the cutting of trees and ground cover required as absorption areas to minimize runoff and reduce flood hazard.

(3) The dumping of any liquid or solid waste which endangers surface or groundwater quality.

(4) Dredging, draining, filling or other alteration of the natural watercourse which will substantially change the pattern or volume of runoff during periods of heavy precipitation to the detriment of community health and safety.

B. Permitted uses. Within the areas designated as water resource conservation areas under § 102-111, only the following uses are permitted:

(1) Forestry and other conservation techniques involving maintenance and preservation of the natural ecology of the lake or water area.

(2) Agriculture, horticulture and nurseries.

(3) Noncommercial recreational uses.

(4) Public parks and playgrounds.

(5) Open space areas connected with residential commercial and industrial planned unit development.

C. Special uses. If a development can be created which is compatible and harmonious with the natural amenities of the conservation area and with surrounding land uses, then request for a special use permit for such development may be submitted. Such requests shall be accompanied by an overall plan of the entire site, showing roads, parking areas, lot lines, easements, the location of tree cover, including the designation of individual trees of 15 inches in diameter or more, the location of other natural and biological features, such as wetlands and areas of valuable wildlife habitat, and the location of proposed structures, existing contours and proposed grading, drainage, utilities and landscaping in such detail as the Township Planning Board and Township Engineer shall require before it may be reviewed by the Planning Board and with such other site plan details as are required by the Land Use Law. The approval of such a request by the Planning Board shall require a finding that:

(1) The development will not detrimentally affect or destroy natural features such as ponds, streams, wetland and forested areas but will preserve and incorporate such features into the development's site design.

(2) The location of natural features and the site's topography have been considered in the designing and siting of all physical improvements.

(3) Adequate assurances have been received that the clearing of the site of topsoil, trees and other natural features before the commencement of building operations will not occur. Only those areas approved for the placement of physical improvements may be cleared.

(4) The development will not substantially reduce natural retention storage capacity of any watercourse, thereby increasing the magnitude and volume of flood at other locations.

(5) The soil and subsoil conditions are suitable for excavation and site preparation and the drainage is designed to prevent erosion and environmentally deleterious surface runoff.

(6) The development will be free from offensive noise, vibration, smoke, dust and other particulate matter, odorous matter, fumes, water pollution and other objectionable influences.

(7) The petitioner will be substantially damaged by being required to place the intended development outside the conservation area.
