Piscataway City Zoning Code
§ 21-802A.2
Establishment of Flood Hazard Areas.
[Added 9-13-2022 by Ord. No. 2022-17]
The Township of Piscataway was accepted for participation in the National Flood Insurance Program on January 18, 1984.
The National Flood Insurance Program (NFIP) floodplain management regulations encourage that all Federal, State, and Local regulations that are more stringent than the minimum NFIP standards take precedence in permitting decisions. The FHACA requires that the effective Flood Insurance Rate Map, most recent preliminary FEMA mapping and flood studies, and Department delineations be compared to determine the most restrictive mapping. The FHACA also regulates unstudied flood hazard areas in watersheds measuring 50 acres or greater in size and most riparian zones in New Jersey. Because of these higher standards, the regulated flood hazard area in New Jersey may be more expansive and more restrictive than the FEMA Special Flood Hazard Area. Maps and studies that establish flood hazard areas are on file at the Piscataway Township Engineering Division Office located at 505 Sidney Road, Piscataway, NJ 08854.
The following sources identify flood hazard areas in this jurisdiction and must be considered when determining the Best Available Flood Hazard Data Area:
a.
Effective Flood Insurance Study. Special Flood Hazard Areas (SFHAs) identified by the Federal Emergency Management Agency in a scientific and engineering report entitled Flood Insurance Study, Middlesex County, New Jersey (All Jurisdictions) dated July 6, 2010 and the accompanying Flood Insurance Rate Maps (FIRM) identified in Table 802A.2(1) whose effective date is July 6, 2010 are hereby adopted by reference.

b.
Federal Best Available Information. The Township of Piscataway shall utilize Federal flood information that provides more detailed hazard information, higher flood elevations, larger flood hazard areas, and results in more restrictive regulations. This information may include but is not limited to preliminary flood elevation guidance from FEMA (such as Advisory Flood Hazard Area Maps, Work Maps or Preliminary FIS and FIRM). Additional Federal Best Available studies issued after the date of this Section 21-8A must also be considered. These studies are listed on FEMA's Map Service Center. This information shall be used for floodplain regulation purposes only.
c.
Other Best Available Data. The Township of Piscataway shall utilize high water elevations from flood events, groundwater flooding areas, studies by federal or state agencies, or other information deemed appropriate by the Township of Piscataway Other "best available information" may not be used which results in less restrictive flood elevations, design standards, or smaller flood hazard areas than the sources described in Section 21-802A.2a and b, above. This information shall be used for floodplain regulation purposes only.
d.
State Regulated Flood Hazard Areas. For State regulated waters, the NJ Department of Environmental Protection (NJDEP) identifies the flood hazard area as the land, and the space above that land, which lies below the "Flood Hazard Area Control Act Design Flood Elevation", as defined in Section 809A, and as described in the New Jersey Flood Hazard Area Control Act at N.J.A.C. 7:13. A FHACA flood hazard area exists along every regulated water that has a drainage area of 50 acres or greater. Such area may extend beyond the boundaries of the Special Flood Hazard Areas (SFHAs) as identified by FEMA. The following is a list of New Jersey State studied waters in this community under the FHACA, and their respective map identification numbers.
