James Keene

CITY MANAGER, PALO ALTO, CALIFORNIA

“Cities are the platform for change in our world today. The Cool Block links the challenges facing our planet to the intimate, personal, social scale of the city block. This program starts and ends with the premise and promise—that the individual, household, and neighbors are the way forward in the face of seemingly insoluble global problems.”
