The $4.4-million extension of Runway 34R at Manassas Regional Airport—a "reliever" airport for nearby Washington Dulles International and Ronald Reagan National—required significant coordination among the project team and the airport's staff and tenants.
A portion of the work occurred within a 100-year floodway, and nearly the entire area fell within a floodplain. In some areas in which, typically, standard chain-link fence would have been constructed, crews installed heavy-duty floodgates instead. The gates replaced existing fencing that was susceptible to flood damage. The new floodgates allow debris to flow through the fenced areas without resulting in any damage.
