Full Breakdown
Chapter 15.36, replaced by Ordinance No. O-042603 on April 15, 2026, forms the Floodplain Management Regulations of the City of New Brunswick together with the flood provisions of the Uniform Construction Code and the New Jersey Flood Hazard Area Control Act (§ 15.36.010). The city was accepted into the National Flood Insurance Program on December 4, 1979. Section 15.36.030 adopts the Flood Insurance Study for Middlesex County dated July 6, 2010 and its map panels, uses preliminary FEMA panels dated January 31, 2014 as best available information, and lists the Raritan River, Mile Run Tributary, Mile Run and Lawrence Brook as state studied waters. Maps and studies are on file at the Office of the City Engineer, 78 Bayard Street.
The city engineer is the floodplain administrator (§ 15.36.040.A). Under § 15.36.050 the applicant files a written application on the administrator's form identifying the development and the land, stating the intended use and occupancy and the valuation of the work, and attaching a site plan and construction documents. A permit becomes invalid when development is not commenced within 180 days of issuance or when work is suspended or abandoned for 180 days, and written extensions run for not more than 180 days each. The administrator can suspend or revoke a permit issued in error or on incorrect information.
The design standards are engineering-heavy. The local design flood elevation adds one foot of freeboard, or the freeboard N.J.A.C. 7:13 describes, to the best available flood hazard data elevation (§ 15.36.030.C), and new habitable buildings need the lowest floor at or above it (§ 15.36.150.B). Where floodways are not designated, no development including fill is permitted unless a licensed professional engineer shows the design flood elevation will not rise more than 0.2 feet (§ 15.36.040.I). Riparian zone development is prohibited without an NJDEP permit (§ 15.36.040.M). The Zoning Board of Adjustment hears flood variances (§ 15.36.080).
Violations & Fines
Development in a flood hazard area without an issued permit, or in conflict with one, is a violation, and the administrator can serve notices of violation and stop work orders (§ 15.36.090). The fine is not more than $2,000, with imprisonment up to 90 days or community service up to 90 days, and each day is a separate violation, after a 30-day period to cure and a court hearing (§ 15.36.010.H). Unlawful solid waste disposal in a floodway or floodplain carries a fine of not more than $2,500.
