Originally, Bergen Beach was an island in Jamaica Bay off the coast of Canarsie, called "Bergen Island" or "Bergen's Island". Most of the island was sea-level meadows, but of the island were uplands, or hilly areas located above sea level. The sea-level meadows were replete with shell middens, or mounds, harvested from univalves and bivalves caught in Jamaica Bay. A bulkhead was built along the shore in the late 1890s, and was later connected to the uplands of nearby Mill Basin. This created a continuous embankment between Mill Basin and Paerdegat Basin, which was later used for the construction of Belt Parkway.
