United States' airspace, and that Floyd Bennett Field was ready for use as an alternate airmail terminal. In March 1936, Farley announced that he had rejected the bid to move airmail operations to Bennett Field because all evidence showed that doing so would cause a decline in traffic and profits. Ultimately, La Guardia was never able to convince the Postal Service to move its New York City operations from Newark to Floyd Bennett Field. Because airmail traffic did not move to Bennett Field, neither did most of the commercial lines, save for American Airlines flights to Boston. Instead, he decided to allow the city to construct LaGuardia Airport in Queens. The new airport was much closer to Manhattan, and it took advantage of the then-new Queens-Midtown Tunnel. Moreover, the federal government created a new airmail contract in which it divided airmail traffic between Newark Airport and LaGuardia Airport once the latter was completed. This confirmed that Floyd Bennett Field was denied an airmail contract not in spite of being located in New York City, but because it was too far from Manhattan. Military and police activity After the 1930 closure of Naval Air Station Rockaway across Rockaway Inlet, a hangar at Floyd Bennett Field was dedicated as Naval Air Reserve Base New York within the larger civilian facility. The Naval Reserve Aviation Unit started using Bennett Field in April 1931, when it moved from Long Island's Curtiss Field to Hangar 1 in Floyd Bennett Field, leasing the hangar for $1 per year. The Department of Docks allowed the Navy to use the airport's other facilities as needed, but left the Navy to pay for any additional expenses on its own. The unit soon moved to Hangar 5 because they required more space. Starting in 1934, the NYPD also occupied a hangar for the world's first police aviation unit. The NYPD Aviation Unit occupied Hangar 4. In 1935, the United States Coast Guard wrote a letter to the city requesting that part of Bennett Field be set aside for Coast Guard use. In 1936, a square parcel of Floyd Bennett Field along Jamaica Bay, covering an approximately area, was leased to the Coast Guard for the creation of Coast Guard Air Station Brooklyn (CGAS Brooklyn). In February 1937, the Graves-Quinn Corporation was hired to create a hangar, barracks building, garages, and "other support facilities" for the new Coast Guard station. The
