Two utilities were sued Tuesday for the widespread destruction from last week’s deadly mudslides that were caused when hillsides ravaged by California’s largest-ever wildfire let loose in heavy rain. An amended negligence lawsuit filed in Santa Barbara County Superior Court added the Montecito Water District to the suit that originally targeted only Southern California Edison. The litigation was brought by three people injured or related to someone hurt, plus a business damaged in flash floods that devastated the coastal town of Montecito. At least twenty people were killed by mudslides and more than 350 homes were destroyed or damaged.
