2019 Map of West Gilgo Beach

About this map

Jones Beach Island serves as a narrow barrier between the open Atlantic Ocean and the sheltered waters of the Great South Bay system. This 2019 survey documents the coastal geography where Hempstead Bay meets South Oyster Bay, separated by a complex network of channels and marshy islands including South Line Island and Black Banks Island. The high-performance transportation corridor of Ocean Pkwy links the isolated beach communities of West Gilgo Beach and Gilgo Beach, which are anchored by landforms like Tobay Heading and Gilgo Heading. The map illustrates the specialized infrastructure required for this fragile environment, from the Amityville Cut to Doughty Blvd, highlighting the constant interplay between tidal flow in Amity Channel and the developed shoreline at Tobay Beach.
