The San Diego County Water Authority on Monday praised Gov. Gavin Newsom’s decision to cut one of the two planned Bay-Delta tunnels and invited him to tour San Diego’s facilities. Board Chair Jim Madaffer thanked the governor for “wisdom and leadership” in officially scrapping the Brown administration’s plans for an $18 billion two-tunnel system for moving water through the Sacramento-San Joaquin Bay-Delta to Southern California in favor of a less-expensive single tunnel.
