SANTA ROSA, Calif. (AP) – The number of buildings destroyed by this month’s California’s wildfires has been boosted again, to 8,400 from 7,700. That’s up from nearly 7,000 homes and other structures that were reported destroyed a day earlier by the fires that hit wine country and other areas north of San Francisco. The number of buildings razed was increased as crews inspected damage in hard hit areas. California Department of Forestry and Fire Protection spokesman Daniel Berlant said assessment is nearly done, but the number will rise as the workers get to areas that have been difficult for them to reach The wildfires broke out Oct. 8 in a large area north of San Francisco in and around the state’s famed wine country. California’s insurance commissioner said preliminary estimates of wildfire losses that started Oct. 8 exceed $1 billion and that the figure is expected to rise. The fires killed 42.
