It’s ludicrous for the Santa Clara Valley Water District board to believe it can steer Gov. Jerry Brown’s $16 billion Delta twin tunnels project by committing to help fund it. The board should stand up to pressure from the state and reject the project when it meets at 9:30 a.m. Tuesday and instead work with California’s next governor on a plan to truly secure a reliable source of water for Silicon Valley while protecting the environmental health of the Delta.
