Green Alleys Handbook (PDF)
Chicago Green Alleys - Chicago, after the success of a demonstration project using permeable pavement, began a Green Alley initiative to use permeable pavement any time it needs to re-pave an alley. Through 2009, more than 100 Green Alleys have been installed and ultimately, almost 2,000 miles of alleyways will be made permeable. The Green Alley Handbook notes that "if all the alleys had a light, reflective surface (high albedo) that reflected heat energy, [they would stay] cool on hot days and thereby reducing the "urban heat island effect." The handbook also mentions the heat island reduction benefits of shade trees and green roofs.Active
