Looking at it on the map, the warning signs are all there: suburban-rural interface, western slope, wooded area with no firebreaks, and a climate with hot and dry summers. Couldn't pay me enough to settle there.
That could be any number of places in the west though, including much of the edges of the Seattle Metro too.
I grew up with fire really, the issue really is the forrest service policy on fire from the early part of the 20th century into the early 90's - which is to say never allowing any fire ever, so because the smaller fires which would remove excess fuel on the forrest floor every decade or two, we now live in a world where every small fire becomes a major conflagration.
Nearly every major forrest fire we have is a byproduct of those forrest management policies.
