Virginia Places has some history of and speculation about continued growth in Northern Virginia.

Under one scenario, steady growth in Fairfax, Prince William, and other counties will lead ultimately to a full build-out of undeveloped parcels in about 30 years. At that point, the road pattern will be in place (for better or worse) and construction of large residential subdivisions would end. Construction would continue to be a significant part of the local economy, as old facilities are replaced with new buildings and transportation systems, but projects would deal with smaller parcels and upgrading of existing systems.
