When USA Today focuses on green alleys, you can feel that this topic of recreating cities has reached a mainstream audience. A recent USA Today article focuses on Los Angeles, Chicago and Seattle efforts to use alleys for environmental benefits and improved community life. Resurfacing alleys with porous surfaces reduces runoff, lowers the burden on municipal storm drains, and improves lake and ocean water quality.
In addition to functional environmental benefits, green alleys turn underutilized spaces into living spaces, places for walking, biking and gathering. The article quotes Suzanne Simmons who worked with her neighbors to close their alley to car traffic and set up instead benches, grills and tables.
