Hoboken, NJ Environmental Rules: Flood Zones (2026)

Chapter 104, first adopted in 1982 and rewritten in full in 2013 under Ordinance No. Z-263, governs any construction, alteration or land-disturbing development inside Hoboken's mapped flood hazard zones. Section 104-6 sets the chapter's reach: it applies to all areas of special flood hazard within the city, but exempts land mapped as "X" or "shaded X." Section 104-7 ties those boundaries to specific federal documents, naming Hoboken's FEMA Community No. 340222 and the August 16, 2006 Flood Insurance Study and Flood Insurance Rate Map panels 0043, 0044, 0106 and 0107 for Hudson County, plus the February 22, 2013 Advisory Base Flood Elevation maps; where the older FIRM and the newer advisory maps disagree, the section directs that whichever imposes the stricter requirement controls.

Anyone building, filling, grading or altering land in a mapped zone must first obtain a development permit from the Floodplain Administrator, whose office sits at City Hall, 94 Washington Street, under § 104-12, with the application showing the elevation of the lowest floor and any floodproofing certification by a registered engineer or architect. The Floodplain Administrator reviews every permit against the floodway encroachment limits of § 104-18 and can send an applicant to the Planning Board for a variance under § 104-15. Section 104-8 backs the whole chapter with a criminal penalty: building or altering land in a flood hazard area without full compliance is a misdemeanor punishable on conviction by a fine of $2,000 or up to 30 days' imprisonment, or both, for each violation, plus all costs and expenses of the case.
