This piece describes two solutions for making a large city cooler: planting trees and using a new mix of porous concrete for parking lots and drive ways. Both solutions, of course, make a lot of sense and seem obvious, but it is good to hear how people are taking steps to improve their urban environment. Also, the piece is clear that any city of any size has an urban heat problem. The producer uses decent sound to illustrate some of the activity. Though this piece could stand alone, it would be stronger alongside the other pieces in the Soundprint series.
