The Barnes Regional Airport Commission in Westfield, Massachusetts, approved a 50-year lease of almost 11 acres of airport property to Gulfstream, a division of General Dynamics. Gulfstream has been operating on adjacent property it owns, plans to create a new $20 million service center for maintenance and other services to its newest corporate jet.

The project is anticipated to add 100 jobs and retain 130 employees.

"We look forward to Gulfstream's expansion and it bringing its new GS650 corporate aircraft to Westfield," said Airport Commissioner Joseph Mitchell.

The lease still must be approved by the City Council. A tax incentive package in negotiation is said to give Gulfstream up to a 50 percent reduction in property tax for the first 15 years of operation; it must still get approval from the City Council and the state's Economic Development and Housing Department.

Airport commissioners said the lease approval is tied to job retention/creation criteria.
