A Fairfax County supervisor who has long sought to raze a federal warehouse site in Springfield is challenging a recent Army study that casts doubt on the plan.

Making better use of the 70-acre General Services Administration site on Loisdale Court has been on Lee District Supervisor Dana Kauffman’s agenda for a decade. In recent months, Kauffman has supported a local push to get the U.S. military to reroute some of the 22,000 new workers destined for Fort Belvoir as part of the Base Closure and Realignment plan onto the property, which is only half a mile from the Franconia-Springfield Metro Station.
