It's good to see so much press on pervious concrete. If you look at Google news with the search term "pervious concrete" you'll be amazed at how many articles are published every week. This article, however, seemed to stir some controversy.
First, I'll applaud the Atlanta Journal Constitution for interviewing Dr. Wanielista for the article. If you want a good source on pervious concrete, Marty is the man -- you won't find many people with more credibility.
However, I'm disappointed that they'd paint pervious concrete in such a negative light with this quote, "Georgia's hard-packed clay soil makes porous pavement or driveways pointless, unless layers of rocks are installed below the pavement to help water drain..." To say 'duh' here would be less than professional, so instead, I'll just say that nobody in Georgia is promoting pervious concrete on clayey soils without an open-graded aggregate base. Maybe a good writer would have reported this as, "Even Georgia's hard-packed clay soils are perfect for placing pervious concrete, with an aggregate base, to reduce the impact of development, and recharge groundwater supplies."
There was a companion article in this series discussing stormwater utilities and the "user fees" they collect. It seems the state and federal government are claiming they don't have to pay these "taxes" to the local government. It will be interesting to see how this one plays out in court, and the impact it will have on sustainable development.
