It looks like 11th street is set to become a nice locally-focus business strip. We already have Red Rocks, Columbia Heights Coffees, Wonderland, El Riconcito, 11th Street Deli, Acuario's, etc.
That said, be prepared to become somewhat active in your community. We have block cleanups, neighborhood pub crawls, and game nights. There is a lot of older people on their front steps just watching the world go by. Take every chance to get to know these people. They have so much knowledge of history and a wonderful perspective on DC.
