Using alleys to fight heat, water runoff

Some interesting facts from a Chicago Sun-Times article on green alleys:

  • Chicago boasts 1,900 miles of public alleys, the largest system in the world
  • Permeable, light-reflective “green alleys” can help cities reduce heat costs and better manage ground water.
  • The asphalt recycles tire rubber in its mix, and the concrete uses “slag” — a byproduct of metal processing — to make it reflective.
  • About 600 tires can be recycled into a 600-square-foot alley.

I always get excited when I learn about projects like this. It’s great when people break away from things that have “always been done that way” and actually come up with something innovative. I like the inclusion of the dark sky lighting.. something that I’m also very big on, it’s nice to know that someone thought enough to not overlook it.
