The legislator who wrote a law modernizing California's water infrastructure says there's no concrete estimate for the cost to respond to worsening drought conditions.

In a press conference held Friday morning at the San Luis Reservoir in western Merced County, Sen. Anna Caballero, D-Merced County, author of last year’s successful Senate Bill 72, said there is no way to know the cost of developing 90 million acre-feet of water by 2040.

Her bill, which Gov. Gavin Newsom signed into law in October, is being implemented and requires the California Department of Water Resources to formulate long-term water supply goals.

“Frankly, we don’t know what the cost will be to meet that goal,” Caballero said, answering a question from The Center Square at the end of the press conference. “It’s speculative to say it’s a certain amount. Will it be expensive? Yes.”

Caballero added she's proposing a bond that could pay for implementing much-needed updates to the state’s water plan.

Meanwhile, certain water infrastructure projects in California have already cost billions of dollars.
