Report says quakes pose big risk to California levees

SACRAMENTO ” A new report sets a high price on the cost to repair breached levees if a major earthquake strikes the Sacramento-San Joaquin Delta.

The report by the California Department of Water Resources says there is a 50 percent chance that 20 delta islands would flood after a 6.7-magnitude earthquake. Repairs could cost up to $2.3 billion and take three years.

In the meantime, water exports to Southern California, the San Francisco Bay area and millions of acres of farm land would be disrupted.

Scientists at the U.S. Geological Survey have said there is a 62 percent chance that a quake with a magnitude of 6.7 or greater will strike the delta region by 2032.
