You could but would it make enough of a difference? Having the structure remain standing, but the entire landscape be totally destroyed (including all major infrastructure like power) doesn't seem like much of a victory.
Not to mention a large portion of damage from wildfires is smoke damage, which your concrete house isn't immune to.
A fully concrete/steel home would likely remain structurally sound, but you're still dealing with intense property damage for everything inside and most probably uninhabitability due to lost infrastructure in the area.
Not to mention during a wildfire you'd still have to evacuate.
My property (rural acreage an hour north of SF) burned twice in the last two years. Black hills everywhere. But looking around now you'd never notice.
Whether or not your home burns makes a huge difference. PG&E had the poles replaced in a week. If you've cut and mowed defensible space, your house will be fine and life goes on like normal. The problem is, folks love their tree-shaded homes and love building at the tops of ridges.
At least in my district, mandatory evacuation is not actually mandatory and (I say this as a firefighter) we aren't going to force you off your property. Especially if it looks like you're prepared. But you really need to be prepared. It's not hopeless - you really can make a huge difference but you have to put the work in long before the fire arrives.
Aside from all the big prep ahead of time, when we evacuate for a fire, is there anything we should be doing at the time of evacuation to help our house survive or easier to partially save... leave interior doors open/closed, leave drapes open/closed, leave hall lights on for firefighters or off to prevent electrical shorts, etc? I've also heard that the fire hydrants are typically on a different water infrastructure from household supply... is that true? If that's true, should I turn my lawn sprinklers on to help make my landscaping less flammable?
Shut all windows and doors to keep embers out. Open or remove flammable window treatments like drapes, but if you have nonflammable (ie metal) blinds keep them closed.
Related preparation: Make sure your soffit and attic vents have screens, and keep the gutters free of leaf litter (install gutter guards!).
Leave the electricity alone. The fire may never approach your home and you never know how long you'll be gone, it could be days and it sucks returning to a fridge full of rotten food. Power will probably go off for the neighborhood anyway.
Spend a little time cleaning up the area around your house. Move flammable items (furniture, toys, etc) either into the garage or away from the house. Shut off the valve at your propane tank, if you have one.
Assuming a rural district like ours, make the location of a garden hose next to the house really obvious. We go from house to house, defending each in turn as the flame front passes over. A brush truck holds ~300 gallons of water, which doesn't last long. Throwing a hose in the tank to top up while we wait delays the need to stop and refill (or call for a water tender, which might be busy).
I don't know the answer to your question about hydrant infrastructure, that sounds like something that will vary locally. In my district almost everyone is on well. Is your landscaping dry fuel or green grass? Personally I have an impact sprinkler on my roof and turn it on as soon as I hear about fire, in an hour the surrounds are saturated. Unless you hear otherwise from an official source, I'd start the sprinklers.
