I spent 7 years living in an area with 1m acre fires, winters that were 4 feet in april and nothing in december. Having a house setup where you have multiple heat sources - important. My fireplace had a fan and my kerosene heater was pretty low maintenance as well - a honda 2200 generator under the eaves - only needed once.
UPSs for power outages.
Chest freezer - put those 1 gallon crystal springs (if in western us) jugs in to have ice blocks.
Have warm clothing. If you live in an HOA, be on top of them plowing both common areas and walk ways (mine was supposed to, FedEx/UPS/DHL all let me know - the walkway couldn't be an ice sheet).
Ensure you have access to a vehicle to get your to the services you need.
For context, I was born/raised SF Bay Area. Moved to Plumas County (north of Truckee) in 2017 for about 8 years. Didn't mind the snow - have a tacoma trd off road. The electric coop was amazeballs even when PGE tried to screw with them. I've since moved. I like rural - but the wild fires and trumptopia kinda soured me.
I live on an island now with a driveway that has 15-20 degree slope. It snows rarely, but garage is insulated and I need to get a heater near the water pipes. It snowed the one day I had to get to the ferry at 650am for jury duty. I'm glad I had the TRD - it wasn't much but waking up to - doo-dee-doo - drive to ferry and unexpected 2" of snow...causes some anxeity.
I hated the reference to burning man. Most burning man people I have dealt with don't plan long term (aside from the event) and the long term planning they do have - isn't usually at their home.
