Part of the problem is that the urban/semi urban development is expanding into the wildland-urban interface (WUI). You have a beautiful scenic setting, surrounded by fire ready kindling. Typically access and egress is at least moderately difficult.

Years ago (1956) I had my first job fighting forest fires in Arizona. I remember that our instructor remarked then that fighting fires in California chaparral was the most dangerous environment. The situation hasn't changed, except for more development in the WUI.
