Southampton Village, NY Environmental Rules: Erosion Control (2026)

Section 93-7A of the Southampton Village Code puts the day-to-day duty on the applicant or developer, who must at all times properly operate and maintain every treatment and control facility used to comply with Chapter 93. Sediment comes out of sediment traps and ponds when their design capacity has been reduced by 50%. For projects meeting Condition A, B or C in § 93-5B(2), a qualified inspector as defined in the SPDES General Permit, Permit No. GP-0-10-001, must inspect and document the effectiveness of all erosion and sediment control practices every seven days, and the reports go in a site logbook.

The controls start on paper. Every SWPPP under § 93-5B(1) must include a site map, a description of the soils, a construction phasing plan, temporary and permanent structural and vegetative measures for soil stabilization, runoff control and sediment control for each stage, dimensions and installation details for each practice, an implementation schedule and a maintenance schedule. The phasing plan follows the New York Standards and Specifications for Erosion and Sediment Control: not more than five acres can be disturbed at any one time unless pursuant to an approved SWPPP. Each contractor and subcontractor involved in soil disturbance must sign a certification statement before starting (§ 93-5D), and a copy of the SWPPP stays at the site from the start of construction to final stabilization (§ 93-5E).

Inspections are called in by the applicant. Under § 93-8A the Stormwater Management Officer can require notice at least 48 hours before the start of construction, installation of sediment and erosion control measures, completion of site clearing, rough grading, final grading, close of the construction season, final landscaping, and successful establishment of landscaping in public areas. If violations are found, the applicant and developer get written notice, and no further work can proceed except site stabilization until the violations are corrected and the work receives approval. Section 93-6C bars any increase in turbidity that results in substantial visible contrast to natural conditions in surface waters. The Village can also require a performance bond, cash escrow or irrevocable letter of credit under § 93-9A, held for not less than one year.
