Vineland, NJ Environmental Rules: Flood Elevation Requirements (2026)

City Code Section 425-71B(3) sets Vineland's local design flood elevation, the minimum elevation to which new construction and substantial improvements in a flood hazard area must be built, always above the base flood elevation shown on the effective Flood Insurance Rate Maps. For a building along a delineated watercourse, the local design flood elevation is the mapped flood hazard elevation plus one foot of freeboard, or the freeboard the state Flood Hazard Area Control Act requires if greater. Where no map or study covers a watercourse with 50 or more acres of drainage area, an applicant must submit either an unexpired state flood hazard area verification plus one foot of freeboard, or an engineering determination under state Method 5 or Method 6 plus one foot of freeboard and any additional freeboard ASCE 24 requires, sealed by a licensed professional engineer.

In AO Zones, the local design flood elevation is the highest adjacent grade plus the FIRM-specified depth number plus one foot of freeboard, or three feet above the highest adjacent grade if no depth number is listed. Development of a new or substantially improved Class IV critical facility, such as a hospital, police or fire station, or emergency operations center, must reach the higher of the 0.2%-annual-chance flood elevation or the flood hazard area design flood elevation, plus two feet of freeboard under ASCE 24.

A Class III critical facility in a coastal high-hazard area needs the same 500-year comparison with one additional foot of freeboard. The Construction Official, as Floodplain Administrator, verifies that every development permit's stated elevation correctly applies these standards before construction begins.
