Basis For Establishing Critical Areas.
The mapping of the critical areas within Frelinghuysen Township is indicated on the map entitled "Critical Areas" which is part of this ordinance. As noted on the map, the basis for the delineation of flood plain areas were the Flood Insurance Rate Maps, panels 5 and 10, prepared by the Federal Emergency Management Agency and dated February 4, 1983. The mapped information shall be deemed conclusive for the purpose of administering the land use control measures of this ordinance: however, the Planning Board or Zoning Board of Adjustment, as the case may be, may request the delineation of the 100-year floodplain along any stream located on a tract which is the subject of a development application, such delineation to be prepared by a licensed engineer.
It should be noted that more flood plain areas exist in the Township than those already mapped. Moreover, the State Department of Environmental Protection, Division of Water Resources, in accordance with the Flood Hazard Area Control Act (N.J.S.A. 58-16A-50 et seq.), has adopted N.J.A.C. 7:13 and will be mapping the "flood hazard areas" in Frelinghuysen Township. The Department of Environmental Protection mapping shall take precedence when completed.
The basis for the delineation of steep slope areas on the "Critical Areas" map were the U.S. Geological Survey maps, dated 1971. However, the Planning Board or Zoning Board of Adjustment may consider other sources of information at the time of subdivision and/or site plan approval.
Additionally, while information depicted on the Critical Areas map has been prepared as accurately as possible; nevertheless, it must be understood that detailed information mapped at such a large scale may not represent the actual conditions on any particular parcel of land. Therefore, the information is not intended to take the place of specific on-site engineering data presented to the Township at the time applications are submitted for approval of a subdivision, site plan, construction permit, and/or any other application which considers the "critical areas" categories of information depicted on the map.
Finally, while not included as a "Critical Areas" environmental factor per se, both Wetlands and Hydric Soils have been mapped as part of the Land Use Plan portion of the Frelinghuysen Township Master Plan, and are subject to regulations in this ordinance and any State and/or Federal laws which may supersede them.
