post last week covered the opening of the Yards Park, a 30 million dollar development project that's part of the Anacostia Waterfront Initiative. The 5.5 acre park features some lovely green space and an (interesting) sculptural bridge (picture, PoP).
I personally think this is a great new development for the area. DC has an amazing waterfront that seems pretty underutilized to me.
A lot of folks thought that the new Nationals stadium would be the impetus for changing this neighborhood, but a combination of factors seems to have derailed this economic development. Many claimed the lack of residential ammenities as reasons they wouldn't consider purchasing a home here--hopefully the addition of Yards Park is a step in the right direction!
9/15/10 Update: I found an enjoyable write-up of this opening on Two DC.
