Two of the most destructive fires in California’s history, the Valley and Butte Fires, ravaged nearly 150,000 acres in Northern California last fall and caused an estimated $1 billion in insurance losses. The Valley fire pillaged 1,958 structures in Lake, Napa and Sonoma counties, resulting in approximately $700 million in insured losses and making it the third most damaging wildfire in state history based on total structures burned. In terms of structures lost, the Butte Fire is the seventh most destructive fire to hit California, damaging 818 structures in Amador and Calaveras counties and causing an estimated $300 million in insured losses.
