Like many communities in California with a mild climate, affordable housing, and scenic wilderness, Butte County (pop. ~230,000) has grown significantly over the past four decades. Broadly, this growth is happening all around the county — both in cities (e.g. Chico, the county seat and largest city, pop. ~94,000) as well as in more rural areas. Looking more closely, however, the specific spatial patterns of Butte’s development reveal conditions that set the stage for the ongoing Camp Fire to become one of the deadliest and most destructive fires in California history.
