On 1 November 1991, the Army held a simple ceremony to signify their takeover of the base, then changed the sign at the main gate to Wheeler Army Airfield. The installation, however, remained on the real property records of the 15th Air Base Wing until 15 March 1993 when an Action Memorandum signed by the Deputy Assistant Secretary of the Air Force (Environment, Safety and Occupational Health) and the Deputy Assistant Secretary of the Army (Installations and Housing) authorized the exchange of Wheeler AFB for Fort Kamehameha Military Reservation. Design Wheeler Army Airfield was constructed in the pattern of the Garden City. These type of neighborhoods are the inspiration of Sir Ebenezer Howard of England, who designed these type neighborhoods in re-action to the industrial company towns that had blighted his nation. The neighborhoods are designed in loops with ample green spaces that were to be shared in common among the residents. The homes within the loops are of the Spanish Colonial Revival style that was flourishing in the 1920s and 1930s.
