The housing boom is going south to along Route 1 Richmond Highway corridor around Fort Belvoir. Area around the base will have the spillover effect of base closure, while Arlington would have to find ways to softened its economic impact. This is part of Pentagon's decision to move eighteen some thousand defense workers to the base.

As land becomes scarcer close to the Capital Beltway and traffic congestion increases, Fairfax officials are encouraging developers to look south and build office parks and complexes on property that by the county's boom-time standards is considered underused. Office development, chiefly for government contractors and technology firms, is a prime foundation of Fairfax's economic strategy -- to the extent that even thriving businesses like Smitty's can be deemed a poor substitute for another well-placed commercial building. With the Pentagon set to relocate as many as 21,000 defense workers to Fort Belvoir over the next six years, the county is hoping that the surrounding area can take on shades of Tysons Corner or the Dulles corridor as private contractors follow the flow of work.
