Hackensack, NJ Environmental Rules: Flood Zones (2026)

Chapter 89, adopted June 3, 2025 by Ordinance No. 27-2025 and administered by the Floodplain Administrator out of the Hackensack Construction Official's office at 216 Union Street, sets minimum requirements for development in flood hazard areas under Section 89-10, covering new construction, substantial improvement, subdivision of land, site improvements, utility installation, manufactured and recreational vehicle placement, and temporary or permanent storage. C. 7:13, since state-regulated flood hazard areas can extend beyond FEMA's mapped special flood hazard areas. Section 89-12 sets the local design flood elevation at the best-available flood data elevation plus one foot of freeboard at minimum, rising to an additional two feet of freeboard for Class IV critical facilities under ASCE 24.

Section 89-5 requires even ordinary maintenance and minor work, such as replacing windows, doors, plumbing fixtures or roofing, to be evaluated by the Floodplain Administrator through a floodplain development permit for compliance with the substantial-damage and substantial-improvement provisions of Section 89-26. Under Section 89-9, these flood regulations supersede conflicting prior flood ordinances but do not repeal zoning, subdivision, stormwater or building-code requirements, and the more restrictive rule governs any conflict.
