The parking lot of the Ashburn Fire and Rescue station is now a Plaza, which has changed the street address of the fire station itself, and the auxiliary buildings also in the parking lot.  

New street address of the station seems to be:
43765 Ashburn Volunteer Plaza, Ashburn, VA 20147

(conflicting reports of Plaza name)
