Chicago's Greener Alleys Program shares insights on sustainable transportation

Chicago is using pervious pavements and reflective materials on its 1,900 miles of alleys to reduce flooding, cut demand on storm sewers, and decrease the city's urban heat island effect. The program is so successful that they are expanding it.

Back in 2004, Chicago's Department Of Transportation had no concept of how to build roads and alleys using pervious materials.

Janet L. Attarian writes, "To overcome this obstacle, the department led an aggressive design and investigative process that involved collecting best practices and sample specifications from around the country. CDOT developed its own specifications through a collaborative process involving CDOT staff, the design team, and a materials testing consultant. Together, they established a series of goals, tested the ideas in a laboratory, and then reviewed the results until the final mix designs, materials, and methods were solidified."

The DOT embarked on a number of pilot projects to test out their new-found knowledge, detailed in the full article.

Laughable Pictures

I was born and raised in Chicago. I'm 62 years old. I really had to gafaw and evoke "Yeah, Right Buddy !" when I saw a picture of a Street Sweeper cleaning a Chicago Alley. That's nothing but a publicity photo. Ask any Chicago resident, and they'll tell you that most drainage tr=enches in the center of our alleys are filled with weeds 7 months out of the year. The photo that goy a full-fledged Belly Laugh was the one that had about 6 Steets & San''(itation) workers doiung actual work while 1 foreman is pointing out what to do! When I was able to gain my composure, a loud 'Spare Me!"echoed the room.It's more like 2 calling in sick to go to a Cubs Game3 reading a newspaper, 1 forman talking on a cellphone while the lackey that's not tenured yet leans on a shovel.
