Check out the Georgia Avenue Community Development Task Force website and read Faraji Whalen's concerns about Wal-Mart's nascent plans for Brightwood. He raises a lot of good points, particularly with regard to how roads and traffic patterns in the immediate area would have to change drastically in order to accommodate a store the size Wal-Mart is planning. What about the loading dock entrance? None of the abutting streets (Georgia, Missouri, 9th, or Peabody) are particularly 18-wheeler-friendly.
Incidentally, the Georgia Avenue Community Development Task Force is a great organization, composed of concerned citizens and stakeholders, that aims to ensure that the new development along the Georgia Avenue Corridor meets the needs of its residents. The group meets biweekly at different locations along the corridor; meetings are announced via a yahoogroup listserv that I encourage you to join.
