After serving on the Las Virgenes Municipal Water District board of directors for over 30 years and on the Metropolitan Water District more than 25, Glen Peterson announced he will retire at the end of the year. The 68-year-old Peterson became a leading expert on water issues in his three decades with water district. “Glen came to the LVMWD board to serve his community, but that service turned into something that became much larger and more significant than the daily operations of a local water agency,” said Dave Pedersen, the Las Virgenes general manager.
