The air show planned for next month may have been canceled at Maine’s former Brunswick Naval Air Station, but the redevelopment authority has been keeping busy. The Midcoast Regional Redevelopment Authority, in charge of repurposing the base and its buildings, says that 214 private sector jobs have been created and that 260 acres and 24 buildings have been conveyed to the private sector by this summer. Also, more than 700 students are expected to enroll this fall at Southern Maine Community College. The base closed in May 2011. Executive director Steve Levesque says the agency is projecting nearly 400 jobs by the end of next year from the current mix of companies at Brunswick Landing. Those include Molnlycke Health Care, Maine Tool and Machine, Kestrel Aviation, and Oxford Networks.
