Acquisition of the site occurred from 1917 to 1959. Real estate records indicate that this installation consisted of 1,168.90 acres fee, 181.67 acres easement, 7.08 acres license and 79.07 acres lease. The area known as Mitchel Field has had various titles, as it has been the site of troop encampments during every war in which the U.S. has engaged. It was known as Camp Winfield Scott during the Civil War, Camp Black during the Spanish American War, and as Hazelhurst Field in 1915. The area was not formally leased until 1 July 1917 when the Government leased the property for the Aeronautical General Supply Depot and Concentration Camp from the Hempstead Plains Company. On 16 July 1918 the installation was renamed for Major J.P. Mitchel, reclassified as an active flying field and eventually became the home of observation, bombardment and pursuit groups. Mitchel Field was deactivated in April 1961, 1076.77 acres fee were reported excess to GSA, and the remaining 92.13 acres fee were transferred to other DoD agencies. According to the SSSS, the principal owners of the site now are Hofstra University and Nassau community College. (Source: U.S. Army Corps of Engineers) « see less

Update (Dec. 5, 2017): We have changed the source of the installation cost data after being notified by the Department of Defense that they erroneously reported their own cost figures on the DERP website. We are now displaying the costs the department says are the most accurate available, from the Pentagon’s DERP database that we received in a FOIA request.
