Officials broke ground Wednesday on a major mixed-use development near the site of the new Nationals stadium officially marking the latest step toward the revitalization of the Anacostia waterfront.

The 42-acre site, formerly called the Southeast Federal Center but now dubbed The Yards, will eventually house 2,800 affordable and market-rate residential units, 1.8 million square feet of office space, significant retail space and a 5.5-acre riverfront public park.
