Green alleys plan could hit streets | Chicago Tribune
This is an interesting article on newer technologies to help with run-off.
“In the Chicago area’s topsy-turvy climate, where droughts and floods are known to take turns causing headaches, a pavement that could help ease both has begun to seep into planners’ thoughts. Used in Europe for decades, so-called permeable pavement allows rainwater to pass through instead of running off into rivers or lakes. Made of either porous asphalt and concrete or paving stones shaped to leave gaps at the corners, the surfaces are just starting to catch on in the area as part of the movement toward “green building,” which seeks to lessen the environmental impact of development.”
