Seaweed Cultivation Program Development

In 2022, Suffolk County was authorized by New York State to add Seaweed to the existing Aquaculture Lease Program (ALP) in Peconic and Gardiners Bays. Based on comments received by the public and key stakeholders through April 30, 2024, we are evaluating the input and considering the expansion of ALP to include seaweed. Should Suffolk County draft an expanded program, it will be available for public comment before it is adopted by the Suffolk County legislature.

A link to the existing ALP maps is provided below. Please click here for more information.
