I first read about the Bayview Rural Village in southern Delmarva in the book, Design Like you Give a Damn. The residents of Bayview, many descendants of slaves from that area, were living in very rundown housing that reportedly was without running water or electricity. The new community was designed to create not only livable housing but a neighborhood surrounded by farmland that the community would farm. This really is meant as a sustainable place in the sense that the community was designed in connection with a primary source of financial and edible sustenance.
These photos don't capture that very well, but since we were driving by, it seemed like I should at least snap a couple shots.
