The Sonoma County Board of Supervisors has voted unanimously to sue Pacific Gas and Electric Co. (PG&E) to recover damages for the utility’s alleged role in last October’s deadly wildfires. The lawsuit is scheduled to be filed in late February, alleging that PG&E facilities were responsible for fires that covered 137 square miles in the county, killing 24 people and destroying more than 5,000 homes.Since the unprecedented fires in both Northern and Southern California last fall, PG&E and other utilities in California have braced for regulatory and legal challenges.
