Edison, NJ Environmental Rules: Flood Zones (2026)

Edison joined the National Flood Insurance Program on August 16, 1982, and its Floodplain Management Regulations, adopted in entirety September 28, 2022 by Ordinance O.2160-2022, work together with the New Jersey Uniform Construction Code, N.J.A.C. 5:23, and the Flood Hazard Area Control Act (FHACA), N.J.A.C. 7:13. Section 33-102.1 sets minimum development standards inside flood hazard areas covering subdivision of land, site improvements and utility installation, placement or replacement of manufactured homes, placement of recreational vehicles, new construction and additions, substantial improvement of existing buildings including repair of substantial damage, installation of tanks, and temporary or permanent storage structures.

Section 33-102.2 establishes where those areas sit: the Township adopted the FEMA Flood Insurance Study for Middlesex County and the accompanying Flood Insurance Rate Maps, both effective July 6, 2010, and specifically listed by map panel number in Table 102.2(1). Because FHACA regulates unstudied flood hazard areas on watersheds of 50 acres or more and most riparian zones, New Jersey's regulated flood hazard area can be more expansive than FEMA's mapped Special Flood Hazard Area, and the more restrictive of the two governs. Maps and studies are kept on file at the Township Engineer's Office, 100 Municipal Boulevard, Edison. Ordinary maintenance and minor work, such as in-kind replacement of windows, doors, cabinets, plumbing fixtures, decks and roofing, still gets evaluated by the Floodplain Administrator through the floodplain development permit against the Township's substantial damage and substantial improvement standards in Section 33-103.14.
