In a 5-2 vote, the Zone 7 Water Agency Board approved the expenditure of $2.8 million as the agency’s share for the next phase of planning on the Delta Conveyance. The conveyance, a Gov. Gavin Newsom proposal, would reduce his predecessor Gov. Jerry Brown’s Twin Tunnels project to one tunnel under the Delta. On Brown’s Twin Tunnels project, Zone 7 paid $280,000 as a placeholder to be sure the agency reserved a spot if the agency wanted to take part.
