If our state wants to remain economically competitive, it must re-engineer the troubled estuary that serves as the hub of California’s elaborate water-delivery system — the Sacramento-San Joaquin River Delta. The best and most viable way to do this is via the single Delta tunnel project proposed by Gov. Gavin Newsom, which the Silicon Valley Leadership Group and our 350 members support. The water that flows through the Delta serves nearly 27 million people in our state and ensures 3 million acres of farmland stays productive. Yet, the current Delta water delivery system – comprised often of simple earthen levees – is fragile and extremely vulnerable to catastrophic disruption from earthquakes, floods, and rising seas.
