More than 30 acres of land have been made available for aeronautical use at Long Beach Airport, city officials announced Tuesday.

The city of Long Beach has released a request for proposals for the land for potential development of aviation-related purposes that would complement adjacent businesses. Five parcels at the site range in size from 128,000 to 487,000 square feet.

“We anticipate interest from both existing tenants and outside parties that will encourage the revitalization of the west side of the airport,” Juan Lopez-Rios, the airport’s deputy director, said in a statement.

The 31-acre site is situated near 90 acres of land owned by Boeing Co. that was formerly used for the manufacturing of the Boeing C-17 Globemaster III military plane, according to the city.

The availability of that much land for aviation purposes has not occurred at the airport since the Long Beach Airport Business Park and Kilroy Airport Center were developed in the 1980s and early 1990s.
