Peripheral Canal 2.0
For decades SoCal pols were pushing the Peripheral Canal project to divert more water from the Sacramento-San Joaquin River system to SoCal. They never quite succeeded in this endeavor. So this would be a new way to take NorCal water to the Land of LA.
BTW, I realize some folks think California is a giant earthquake fault, but comparing maps of faults in the Bay Area and Central Valley and of the proposed route for the project, the route is not near any earthquake fault, and even farther from the major faults, the San Andreas and Hayward Faults.
