One other item of note at the site--as seen below, beams have been placed connecting a portion of the main concrete walkway at Diamond Teague Park to what will be Dock 79's plaza and Anacostia Riverwalk footprint, and without realizing it I did a pretty good job of matching my photo of the beams to the rendering of the same location:

There will be over 15,000 square feet of retail in the building, and in a press release from developer MRP Realty last week, John Begert is quoted as saying the retail space is being "programmed" with "a dynamic mix of local authentic restaurant operators," though no retail tenants have been announced as yet.

Most of this retail space will be facing the "esplanade" and this plaza, which MRP's press release says is "inspired by the concept of the “ecotone,” an ecological term referring to the transitional zone between two ecosystems."

The plaza also is directly south of the "grand staircase" of Nationals Park, ensuring that (some) views of the river from those steps and the viewing platform on the upper concourse are not completely lost.

The building is expected to deliver in the summer of 2016, and will have a ground-floor club/game room, a health club, a rooftop swimming pool, WiFi, air-conditioned storage, bike storage, a business lounge, and a 24-hour front desk.

The subsequent phases of the six-acre project are currently envisioned as a second residential building with 282 units and 5,600 square feet of retail, followed by a 313,000-square-foot office building with 11,500 square feet of retail, and then a fourth building that could be a hotel or another residential or office building, with 260,000 square feet of space and 12,600 square feet of ground-floor retail. (The footprint of the final two phases is, however, right up against the western end of the existing Douglass Bridge, so it might be awhile before those come to pass.)
