Big city mayors (and even some smaller city leaders) are making a big splash! LA’s Antonio Villaraigosa is dealing with crime; Chicago’s Richard Daley is turning that dusty city green; Philadelphia’s John Street has agreed to an important re-thinking of seven miles of highly developable waterfront; Miami’s Manny Diaz is working closely with Donna Shalala, President, University of Miami, to harness anchor-institution strength to downtown development. And Michael Bloomberg became a winner when he took on New York City’s school system. But of equal note is his soon-to-be announced PlaNYC, a strategic vision for 2030.
