Two days ago, D.C. United officially submitted the information needed (specifically, the Planned Unit Development) by the District of Columbia Zoning Commission, which includes the most detailed plans to date for the stadium and stadium site at Buzzard Point. Let's take a brief tour through these documents, to which I've linked at the end so you can find everything that I didn't.
But first, some high levels thoughts. The biggest thing that stuck out to me was how much the constraints of this particular site played into the design of the stadium. The Pepco facilities played a defining role because of the easement they have, and they can't build out the west seating bowl to the same depth as the other seating areas.
