In case you are cut off and can't evacuate your home needs to be made as safe as it can be. We cut trees where there is distance between them, out 30-50' from the house and trim limbs 14-18' from the ground. We keep the weeds and grass mowed away from the house and store our firewood 70+ feet from the house. In addition our roof is metal, we have stone fascia on the exterior and a misting system for the only exposed wood which is our deck. Putting a sprinkler on the deck would drain the well in short order but a misting system would run for days if needed.
It is everyone's responsibility to protect their own home or property and procrastinating doing so will probably be to late. Getting a wildfire experts opinion is also a good idea. Our community doesn't have any area's where the fuel has been removed - like our many meadows, but we do have several lakes that could be utilized in an emergency. The area around our community center would be a good place to hunker down if the grasses were mowed, which they are not.
We believe our home would be relatively safe but many homes in our area are log homes that have a flammable coating of exterior sealer on them and trees close to the structure. Our house has been rated by two wildfire experts as being better than excellent for wildfire. In short they believe it would survive a wildfire and they had no suggestions to make it more safe. We are required to keep our propane tank hidden from sight and many use what is known as a coyote fence made of wood to hide theirs which is fuel. Ours is enclosed in a solid stone and mortar enclosure with a metal roof over it. There is no guarantee in a wildfire but we have taken all the needed steps to protect our home and property as best we can. Our survival plan has also been reviewed by experts and turned out to be identical to the survival plan they teach their firefighters.
All communities are different and individual situations within the community are different but taking steps outlined as in the link: https://www.ready.gov/wildfires and other on line links will help make your home safer in case of wildfire emergency. Wildfires are unpredictable and planning ahead to protect your home/property and yourself by formulating a plan and then carrying it out is vital to survival. A fast moving wildfire could cut you off and then is not the time to start with preventive measures.
The next and last segment is what happens if you evacuate and are kept from returning to your home for several days or weeks. Hopefully what we have done and had verified by experts on wildfire mitigation will help others to stay safer in case of wildfire. There are no guarantees of survival in a wildfire but taking proper measures ahead of time just may help improve your odds of surviving.
