Permits, made simple
Every Long Island shoreline has its own rules
DEC sets the state layer. Then your town, city, village or Town Trustees add theirs, and they differ a lot.
Do you qualify for DEC's fast-track permit?
In-place or landward replacement, up to 18 inches higher, no application fee, but not near tidal wetlands, eelgrass or erosion hazard areas.

How much does a bulkhead cost on Long Island?
Published 2026 ranges run about $350–$550 a foot for timber, $450–$700 for vinyl and $600–$900 for steel sheet pile, and one LI contractor quotes $500–$1,500 a foot all-in. A typical 75–150 ft canal lot in vinyl lands around $50,000–$100,000 before unusual extras.
Do I need a permit to replace my bulkhead?
Almost always for a full replacement. NYSDEC's general permit for Nassau and Suffolk covers in-place or landward replacement of an existing, functional bulkhead, with no application fee. You'll also need your town, city, village or Town Trustees permit, and sometimes Army Corps review.
