The Anacostia Waterfront Initiative, the wide-ranging approach via city and federal investments to revitalize the Anacostia River and its environs, is celebrating its 10th birthday, with a series of events next week tied to the riverfront. Some of them you're already aware of, like the dedication ceremony at the Yards Park on Sept. 7 followed by the "grand opening weekend" of events Sept. 10-12. But there's also some other happenings, including an "Anacostia Conservation Service Event" at Diamond Teague Park at 9 am on Sept. 8, a "transportation open house and tour" at the 11th Street Bridges project office on Sept. 9 from 10 am to 2 pm, along with other events at Kingman Island, Marvin Gaye Park, and the Southwest Waterfront.
