September's Lexington Green Scene was held at the Home Builders' Association of Lexington on September 1. Attendees networked inside and on the back patio until they were invited out to the front paking lot to view a demonstration of just how well pervious concrete can handle a deluge of water. Finley Messick, from the Bluegrass Concrete Promotion Group -- the sponsor of September's Green Scene -- explained the technical aspects of pervious concrete as more than 1500 gallons of water were dumped out of a concrete truck onto the pavement. The results were impressive. All of the water was absorbed into the structure of the driveway.
