A. 
It is hereby found that certain streams, creeks and waterways of the Township are subject to recurring flooding, that such flooding damages and endangers life and public and private property and facilities, that this condition is aggravated by developments and encroachments in the floodplain and that the most appropriate method of alleviating such condition is through regulation of such developments and encroachments. It is therefore determined that the special and paramount public interest in the floodplain justifies the regulation of property located therein as provided in this chapter, which is in the exercise of the regulatory power of the Township, for the protection of the persons and property of its inhabitants and for the preservation of the public health, safety and general welfare.
B. 
The intent of this article shall be to protect areas of floodplain subject to and necessary for the containment of floodwaters and to permit and encourage the retention of open space land uses which will be so located and utilized as to constitute a harmonious and appropriate aspect of the continuing physical development of the Township.
The specific objectives of this article are:
A. 
To combine with present zoning requirements certain restrictions made necessary for flood-prone areas to promote the general health, welfare and safety of the Township.
B. 
To prevent the erection of structures in areas unfit for human usage by reason of danger from flooding.
C. 
To minimize danger to public health by protecting the quality and quantity of surface and subsurface water supplies adjacent to and underlying flood hazard areas and promoting safe and sanitary drainage.
D. 
To permit only those uses which can be appropriately located in the floodplain, as herein defined, and which will not impede the flow or storage of floodwaters or otherwise cause danger to life and property at, above or below their locations along the floodplains.
E. 
To provide sufficient drainage courses to carry abnormal flows or stormwater in periods of heavy precipitation.
F. 
To reduce the financial burdens imposed on the community, its governmental units and its individuals by frequent and periodic floods and overflow of lands.
G. 
To protect adjacent landowners and those both upstream and downstream from damages resulting from development within a floodplain and the consequent obstruction or increase in flow of floodwaters.
H. 
To protect the entire Township from individual uses of land which may have an effect upon subsequent expenditures for public works and disaster relief and adversely affect the economic well-being of the Township.
I. 
To maintain undisturbed the ecological balance between those natural systems elements, including wildlife, vegetation and marine life, dependent upon watercourses and water areas.
J. 
To protect other municipalities within the same watershed from the impact of improper development and the consequent increased potential for flooding.
K. 
To provide areas for the temporary natural storage of floodwaters.
L. 
To require that uses vulnerable to floods, including public facilities, be constructed so as to be protected from flood damage in accordance with the purpose and requirements of the National Flood Insurance Program, P.L. 93-234.
A. 
This section consists of this text and the floodplain map prepared by the Township as to the delineation of floodplains. Such map is on file in the office of the Township Clerk and is incorporated in this section by reference as though fully set forth in this text. However, the Planning Board Engineer may modify the one-hundred-year storm criteria based on specific circumstances.
B. 
All other streams and waterways in the Township not included above are deemed to be floodplains. Twenty feet on both sides of streams, as measured from the center line of streams, are presumed to be floodplains in the absence of proof to the contrary.
C. 
This section shall also consist of any and all reports, maps, revisions and amendments of these texts as may be prepared from time to time, provided that such additional documents are in agreement with the Planning Board Engineer, Corps of Engineers, Soil Conservation Service or any agency of the United States government authorized to define floodplain criteria.
D. 
In cases of doubt, uncertainty or a dispute as to the exact limits of the floodplain, the floodway or flood hazard area in a proposed development, the applicant's engineer shall submit all of the appropriate floodplain data, topography, hydrology, hydrolics and any other information required by the Planning Board. After receipt of the complete data, the Planning Board Engineer, upon the application and with the consent of the landowner, shall determine the precise location of a floodplain, floodway or flood hazard area limit by close inspection, field survey or other appropriate method and cause the same to be marked on the ground, notifying the landowner, the Building Inspector and the Planning Board of the results thereof. The cost of such engineering shall be borne by the applicant.
A. 
The FP Floodplain Conservation District shall be deemed an overlay on any zoning district now or hereafter applicable to any lot.
B. 
Should this district be declared inapplicable to any tract, the zoning applicable to such lot shall be deemed to be the district in which it is located without consideration of this article. In appropriate cases, the center line of the streams shall be the district boundary line.
C. 
Should the zoning of any parcel, or any part hereof, in which this district is located be changed through any legislative or administrative actions or judicial decision, such change shall have no effect on this district unless such change was included as part of the original application.[1]

In reviewing applications, the Planning Board shall consider and be guided by the purposes, policies and specific objectives set forth in this article and, in addition, shall apply the following standards:
A. 
As to developments in the floodway, primary consideration shall be given to preserving this area by defining the minimum capacity required for the passage of flood flows without aggravating flood conditions upstream and downstream. Encroachments therein shall therefore be permitted most sparingly and only in cases in which the public interest will be served, such as bridges, roads, utility installations and the like, and the temporary storage of materials or equipment in connection therewith and during the construction thereof, or where the obstruction is minimal, such as surface parking or recreation areas, open fencing and the like, and then, in either case, only in accordance with conditions designed to limit the obstruction to the practicable minimum.
B. 
As to developments in the flood hazard area outside the floodway, primary consideration shall be given to the protection of persons and property involved in the development, and such consideration shall not be avoided by the waiver of the applicant. Normal accessory uses shall be permitted only where the building or structure is not designed or intended as a human dwelling place and will not, by reason of its size, shape, construction or location, have any adverse effect upon the functioning of the floodway.
