Alexandria officials are weighing a special parking district in neighborhoods on Seminary Road near the Mark Center, the Pentagon’s new home for thousands of defense workers come September. City officials are worried about nightmarish traffic conditions that are likely to occur once thousands of employees begin commuting to work along Seminary Road and Interstate 395, the intersection where the Mark Center office space is located. The move is mandated as a part of the Army’s Base Realignment and Closure plan.

While 6,400 employees will begin working at the facility by Sept. 15, only 3,700 spaces have been built for employees to park. The lack of on-site parking is by design — officials wanted to discourage employees from driving in single-occupancy vehicles and encourage carpooling to work.
