The recent Transportation Research Board (TRB) conference had a session about redeveloping Tysons. Among others, Ron Kirby from the Metropolitan Washington Council of Governments gave a presentation and Robert Cervero from UC Berkeley. I will try to post the various presentations. The blog, Greater Greater Washington wrote about the TRB session and the plans to redevelop this 'edge city.'
