What we're doing to be more "green"
This division is upgrading the county’s traffic signals to energy-efficient LED technology and anticipates completing the conversion of approximately 200 signalized intersections in summer 2008. Traffic signals that use LEDs consume 80-90 percent less energy and generally last five to seven years, compared to just a year for a comparable incandescent light signal.
