Flushing Airport was decommissioned in 1984. Much of Linden Place in College Point was also closed due to frequent flooding near the airport, which had been built on a wetland atop Mill Creek. There were several proposals to redevelop the airport site, none of which were successful. One plan in 1986 called for the site to be redeveloped as a large heliport, though the project ultimately failed seven years later. Several large development projects were constructed around the airport site in the late 1980s. These buildings included three projects inside the CPCP campus, as well as another building at Linden Place and 31st Road. Floor space in these buildings rented out at an average of , a relatively expensive rate at the time. This was due to its proximity to major transportation connections such as the LaGuardia Airport and the Bronx–Whitestone Bridge, as well as the lack of parking in nearby downtown Flushing.
