No. In 2006, the Board of Supervisors discussed whether Contra Costa County should consider closing Buchanan Field and repurpose the land for commercial and residential development. After a thorough review of the economic and community benefits associated with Buchanan Field, the Board of Supervisors affirmed that the Airport is too valuable a resource to lose. A recent article written by Karen Mitchoff, District IV Supervisor, reaffirms the Board’s commitment to the continued development and success of Buchanan Field, which is a key piece to the Bay Area’s transportation infrastructure. Following World War II, Buchanan Field was deeded by the federal government to Contra Costa County with the condition that it would operate as a public airport in perpetuity. Federal Aviation Administration grant assurances associated with airport improvement project funds also obligate the County to continue operating the Airport.
