Last November, the California Coastal Commission approved a permit for a sprawling, $330 million seawater desalination facility in Marina—a blue-collar city of 22,500 residents that is located about 15 minutes north of the more affluent community of Monterey. If approved, Cal-Am’s desalination plant would produce 4.8 million gallons of freshwater per day and would be the first seawater desalination plant constructed in California in nearly a decade.
