The waterway was an important part of a failed plan to transform
Jamaica Bay into an alternative port to
New York Harbor. Such a plan had been entertained in the 1910s, but was ultimately unsuccessful. Planners wanted to create a spur of the
Bay Ridge Branch south to Flatlands, with two branches to Canarsie and Mill Basin. A connection to
Staten Island would be built via the planned
Staten Island Tunnel, which would in turn allow freight to be delivered and shipped to the rest of the continental United States. The
Port Authority of New York and New Jersey offered to build the new railroad link for $2 million and lease it to the city. In January 1931, the
New York City Board of Estimate approved a plan to build railroads on both sides of Paerdegat Basin, connecting the LIRR to
Canarsie Pier to the east and to
Floyd Bennett Field to the west. However, the plans for rail service to the rest of Brooklyn went unrealized. The only project that was completed was the dredging of Paerdegat Basin to a depth. In the 1950s and 1960s, much of the city-owned land around the basin was sold off to private developers. The neighborhoods of
Georgetown and
Bergen Beach were built near its banks. ==Sewage treatment plant==
