Huntington, NY Environmental Rules: Erosion Control (2026)

Article II of Chapter 170, added to implement minimum stormwater and erosion controls beyond Article I's illicit-discharge rules, applies under § 170-24(A) to all land development activities affecting 43,560 square feet (one acre) or more, and to smaller disturbances that are part of a larger common plan of development or sale even if phased across different schedules. Section 170-25 exempts routine maintenance disturbing less than five acres, personal gardening on one- or two-family lots, emergency work to protect life or property, fencing and utility pole installation, and any project that already had a building permit issued on or before January 1, 2008.

Section 170-28(A) bars issuance of a building permit or approval of a site plan or subdivision in any zoning district until a Stormwater Pollution Prevention Plan (SWPPP) is submitted and, for projects disturbing five or more acres, sealed by a Licensed Professional Engineer. The SWPPP must be posted on-site from the start of construction to final stabilization; failing to post or retain it is itself a violation. Section 170-34 requires sediment to be removed from traps or ponds once capacity is reduced by fifty percent, and for larger projects a qualified professional must inspect controls every seven days and within twenty-four hours of any storm producing half an inch of rain or more.

Before a Certificate of Occupancy issues, § 170-36 requires the owner to record Covenants and Restrictions binding future owners to maintain any stormwater management system, or the Town may instead accept dedication of the system.
