Oh, I've wanted to post this rumor for so long (and have hinted at it on Twitter) but never could bring myself to pull the trigger when I couldn't get anything out of Monument or DDOT or any first-level source. But,
here's WBJ going where I wouldn't (subscribers only): "[The District Department of Transportation] has signed a letter of intent and is close to a deal on a 10-year lease for 150,000 square feet in Monument Realty's Half Street building at
55 M St. SE, according to sources." Neither Monument nor DDOT would confirm to WBJ either, with DDOT spokesman John LIsle quoted as saying, "We are hoping to move this year. It may be ambitious, but that is our goal."
Originally DDOT was going to move to the Anacostia Gateway project, but that was cancelled a few months ago. WBJ says that, between DDOT's space and existing tenant Sayres and Associates (who apparently will be adding another 10,000 square feet to their lease), 55 M will be about two-thirds leased.
