The first 300-plus employees (from the Pipeline and Hazardous Materials Safety Administration) have indeed begun moving in to the new US Department of Transportation headquarters on M Street. The moves are scheduled to take about nine weeks, with the east building filling up first over the next few weeks, the west building arrivals then scheduled to start in mid-May, and the nearly 5,000 staffers should almost all moved in by June 30 (DOT has to be out of the Nassif building in SW on July 1 or else the rent goes from $1 million a month to $4 million, I've been told). Be nice to the new arrivals, and welcome them to the neighborhood--I'd say we should all show up at the front door with bundt cakes, but given the realities of post-9/11 "security", we'd probably be shot on sight.
