A study of Southern California Edison‘s response to the fierce windstorm that ripped through the region last fall found 70 ways the utility could improve its response to the next disaster.

The study, commissioned by Edison and released Wednesday, determined the utility responded appropriately in some ways to the windstorm, which knocked out power to more than 220,000 Edison customers, toppled thousands of trees and 250 power poles and caused tens of millions of dollars’ worth of damage to businesses, cars, homes and government property.
