NYSDEC Tidal Wetland Permits — Long Island, NY
The New York State Department of Environmental Conservation regulates most waterfront construction on Long Island. Sea Tech manages every step of the NYSDEC permit process—from initial strategy to final approval.
When a NYSDEC Permit Is Required
Any construction, excavation, or placement of fill within or adjacent to tidal wetlands in New York State requires a NYSDEC Tidal Wetlands permit. On Long Island, this covers most waterfront work including:
- Bulkhead construction, replacement, and repair
- Dock, pier, and floating dock installation
- Dredging and excavation in or near tidal waters
- Shoreline stabilization and bank restoration
- Ramps, gangways, and waterfront access structures
- Marina and boat slip improvements
- Any fill or grading within the regulated adjacent area
