Find a vetted marine contractor in Southold, NY

Who licenses marine contractors in Southold

• Under DEC's tidal wetlands program, almost any activity that will alter wetlands or their adjacent areas needs a permit, and those areas reach up to 300 feet inland from the wetland boundary outside New York City.
• Replacing broken boards on a functional dock does not require a DEC permit, the agency says, but changing the dock's length, width or position does.
• Besides DEC, the United States Army Corps of Engineers has jurisdiction, and DEC notes that a Corps permit may be required whether or not DEC requires one.
