Oyster Bay, NY Environmental Rules: Erosion Control (2026)

L. No. 6-2018, applies to all land development activities as defined in § 204-6, generally construction disturbing an acre or more. Section 204-7 bars the appropriate board from approving any land development activity requiring a Stormwater Pollution Prevention Plan (SWPPP) until that plan is prepared and approved under the chapter's specifications, and an owner or operator subject to the state MS4 permit cannot start construction until their SPDES discharge authorization is in effect. Where more than five acres will be disturbed at once, § 204-7 requires a qualified inspector to run erosion and sediment control checks at least twice every seven days, with the two inspections at least two full days apart, and stabilization measures must begin by the next business day once disturbance stops.

Section 204-8 sets the design standard: practices built to the New York State Stormwater Management Design Manual and the November 2016 Erosion Control Manual are presumed compliant, and no activity may cause turbidity that visibly contrasts with natural water conditions. Section 204-11 lets the Stormwater Management Officer require 48 hours' notice before key construction milestones, from clearing through final landscaping, and halt further work if inspections turn up violations, aside from stabilization work. Enforcement under § 204-13 runs from a written notice of violation, through stop-work orders, to fines: up to $350 for a first offense, $700 for a second within five years, and $1,000 for a third, with each week of continued violation counted separately, plus the Officer's power to withhold a certificate of occupancy or order the land restored at the violator's cost.
