One of the Pioneers of Conservation Design

Conservation Design Forum Inc. (CDF) does some of the best LID and conservation-based design and water resources engineering out there. CDF is based in Chicagoland, with offices in Elmhurst, IL and Ann Arbor, MI. I had the great opportunity to intern with them in the summer of 2009, and I had a blast. Too bad they don't have more work for burgeoning urban planners like myself!
Here's one sample graphic, but you can find many more at their website, cdfinc.com.
