Program Maps

Map of Shellfish Cultivation ZoneThe Shellfish Cultivation Zone map shows the area within which shellfish leases can be issued. This 29,969 acre zone includes former New York State Department of Environmental Conservation-issued Temporary Marine Area Use Assignment locations; historic, private oyster grants; and other contiguous areas where the impacts/conflicts of shellfish aquaculture activities on environmental resources/socio-economic concerns will be minimal. New shellfish aquaculture leases will be limited to a total of 60 additional acres per year, for a maximum of 300 acres during the first five years of the program, and a total of 600 acres by the tenth year of program implementation. 

The County has determined that no changes will be made to the Shellfish Cultivation Zone and the respective program maps during the fifth year of the program. This decision is based on the fact that no objections were received by the County during the 45-day Public Comment Period, which requested written comments on the Shellfish Cultivation Zone. While the County also considered other factors in addition to any public comments received in its review of the Shellfish Cultivation Zone, it was determined that incorporation of these minor changes relating to these factors would have had no significant effect on the Shellfish Cultivation Zone, or on the extent of the area within which sites could be made available for lease over the next five years. The County will instead focus on conducting an in-depth review of the Shellfish Cultivation Zone and all other aspects of the Lease Program during the next five-year period.



Map 1: Shellfish Cultivation Zone

The Aquaculture Lease Sites map was constructed as a planning tool to aide the Department of Planning in the implementation of the Shellfish Aquaculture Lease Program. A grid system was overlaid onto the Shellfish Cultivation Zone, and each grid was designated by an ID #. Additionally, the Temporary Marine Area Use Assignments and historic, private oyster grants were also shown on the map, and labeled and numbered with an alphanumeric designation. 

Map 2: Aquaculture Lease Sites

The Interactive Aquaculture Lease Status Map was created by Suffolk County to aide the public and potential applicants. Essentially, this map depicts the status of lease site locations within the Shellfish Cultivation Zone, i.e., whether a site has been leased, has been applied for, or is available for leasing.

The Department of Planning utilized information derived from the Peconic Estuary Program’s Benthic Mapping for Habitat Classification in the Peconic Estuary to develop the maps below. These maps may be useful to potential applicants when applying for a lease site location.
