Monday Properties got some good news over the weekend when the Arlington County Board of Supervisors approved the firm's plans to replace two of its Rosslyn office buildings (1401 Wilson Blvd and 1400 Key Blvd) with a new 1M SF mixed-use development. The buildings' parking garage is where Deep Throat (aka the FBI's Mark Felt) held secret meetings with Washington Post reporter Bob Woodward. In place of the buildings, Monday will construct a new 513k SF office building (on the right), and a 275-unit, grocery-anchored apartment complex. (Clandestine meetings can still take place in a location where nobody goes, the grocery's rhubarb section during winter. It's a summer delicacy, people.)

Arlington County has already commemorated the history with a plaque outside the garage (which we snapped yesterday), and the plaque will stay put despite the oncoming redevelopment.
