Last week, Northern and Southern California state legislators had a rare breakthrough over one of the state’s most divisive issues — water. The Joint Legislative Audit Committee voted to instruct the State Auditor to launch an audit of Governor Jerry Brown’s proposed Delta Tunnels. Recent revelations show the project has murky funding and even supporters know the tunnels cannot be built on a financial house of cards. The Delta Tunnels would be 40-foot tall, 35-mile long tunnels dug beneath the San Francisco Bay-Delta estuary.
