Huntington, NY Environmental Rules: Flood Elevation Requirements (2026)

Town Code § 168-13(D)(1) requires floodplain development building permit applicants in Zones A1-A30, AE, AH or a data-backed Zone A to state the proposed elevation, relative to mean sea level, of the lowest floor, including any basement or cellar, and then, once the lowest floor is built, to submit the as-built elevation certified by a licensed professional engineer or surveyor. Coastal high hazard structures in Zones V1-V30 or VE follow the parallel requirement in § 168-13(D)(2), certifying the bottom of the lowest structural member instead.

The Local Administrator, the Director of Engineering Services, is the official who receives these certificates under § 168-14(C)(1), and the section warns that any further construction undertaken before that certification is submitted and reviewed proceeds at the permit holder's own risk; deficiencies found in the data are grounds for a stop-work order under § 168-14(C)(3) and § 168-39. Manufactured homes must have their certificate filed upon placement on site, and recreational vehicles staying 180 consecutive days or longer without a highway-ready license need one too.

Under § 168-14(F), the Town retains these as-built elevation certifications, along with floodproofing certificates and permit records, for public inspection. Section 168-14(E) ties the certificate of occupancy itself to this documentation: occupancy in a special flood hazard area cannot be authorized until the Local Administrator confirms compliance based on the certified elevations, inspections and any floodproofing or anchoring conditions attached to the permit.
