First, at right (click to enlarge), a rendering of the Twelve12 development's southwest corner at 4th and Tingey SE, now updated to show in the corner ground-floor retail space that Sweetgreen will be coming to when the project is completed in mid-2014.

And below, an overhead view of what some of the DC Water acreage could look like if/when Forest City's plans to Yard-ify the site come to fruition:

Working from the far left, you see Nats Park at 1st Street and the two green-roofed residential buildings totalling 625ish units, along with the 16-screen movie theater just to their east. There's also a whole lot more grass and greenery around the two DC Water buildings that would remain on the site, the historic Main Pumping Station and also the more midcentury O Street station building by the river. And, if you know what you're looking for, you can see that Diamond Teague Park has been expanded northward, and Potomac Avenue has been extended one block east to a new street (1 1/2 Place) that would run between the theater and the residential buildings.

(There's also a couple of other interesting tidbits on this drawing, including two new buildings at far right just to the north of the Yards Park's great lawn, and two other buildings just to the north of the theater and 1st street buildings. All of these are within the footprint of the Yards, on sites currently occupied by surface parking lots. But those are probably still a good ways off. And you can also see at the very bottom right the first hint of the marina that is supposed to be coming to the Yards Park someday.)
