NYC requires erosion and sediment control on all construction sites. DOB mandates Erosion and Sediment Control Plans for sites disturbing more than 1 acre. DEP enforces additional requirements under the NYC Construction Stormwater Permit program for MS4 areas.
All NYC construction projects must implement erosion and sediment controls to prevent soil from entering streets, storm drains, and waterways. For sites disturbing 1 acre or more, a SWPPP (Stormwater Pollution Prevention Plan) is required under the NY State SPDES General Permit for Construction Activity (GP-0-20-001), and DEP administers the NYC Construction Stormwater Permit program. Required controls include silt fences, construction entrances with stabilized tracking pads, sediment basins, and erosion control blankets. DOB requires erosion control measures as part of excavation and foundation permits. The NYC Construction Codes mandate protection of adjacent properties from soil movement (Admin Code §28-3309). In MS4 areas, DEP conducts independent inspections of erosion controls. Projects in waterfront or wetland areas must also obtain permits from NY DEC and the Army Corps of Engineers. During major storms, enhanced erosion controls are required.
Inadequate erosion control: DOB violation with fines starting at $2,500. DEP enforcement for permit violations: up to $10,000 per day. NYSDEC can issue penalties under the state SPDES permit. Damage to adjacent properties from erosion: civil liability.
