[State - Locality] Illinois - Chicago [Initiative Type] Demonstration Project [Link] Permeable Alleys [Date] Completed [Title & Description] 
Cool Paving Demonstration Alley - In the fall of 2001, the Chicago Department of Environment reconstructed an asphalt alley using a permeable system. Using a porous gravel structure the city was able to eliminate formerly chronic flooding without using the sewer system, while reducing the heat island effect by eliminating dark, heat absorbing surfaces. This paving can absorb 3 inches of rainfall per hour, allowing rainwater to soak into the ground and reducing polluted runoff and flooding.
