Stay or go the one thing that is sure to help is setting up your property to be fire resistant and defensible. Substituting metal or tile roofing for wood shakes, or even asphalt shingles, makes the house much more likely to survive. Substituting fire resistant siding, like Hardi-board, for wood siding helps a lot. The modifications that can make your house more fire resistant are too numerous to go over in detail but I'll assume you get the point.

Landscaping makes a big difference. Getting flammable trees and brush well away from the house is important. A wide gravel walkway that rings the house is a great assistance in keeping creeping ground fires at bay.

Having a good water supply, large pool, cistern, pond, or reliable high-output well can make a decisive difference in convincing firefighters that your house is safe enough to actively defend.

With a well designed fire-resistant house and a good water supply you can reasonably add power and pumping capacity, and some basic firefighting gear, and make an active defense possible. Having the capability does not obligate you to do so. In a couple of cases in California municipal firefighters made use of such homeowner supplied capabilities to save the house.

Last year I started reading about Australians who installed fire shelters on their property. The idea being that if all else fails you can hunker down in a fireproof bunker that is located in a spot well away from anything that will burn. This came up as an alternative after a number of people waited too long and died in their vehicles trying to make a run for it.

Such a structure might double as storm shelter and root cellar. In most places it's a long shot you will ever need it. But for a location that faces a lot of storms and burns over regularly, or at least faces the risk, it might be worth it.
