A recent study conducted by Christopher Leinberger of the Brookings Institution, with guidance in part from Jared Lombard of the Atlanta Regional Commission and Georgia Tech Professor Ellen Dunham-Jones claims that "WalkUPs" - walkable urban places - will be the primary location of economic growth in metro Atlanta. "The market has spoken," Leinberger says in the study. "It is now time for public policy to reflect this new market demand by putting in the necessary infrastructure and zoning."
