I'm not sure there's an appropriate design for something to survive a major forest fire.

That’s right. Most people have not ever seen large-scale fires and don’t know how powerful they are. As a fire grows larger, it grows in intensity and spreads faster. A campfire needs tending or it goes out. A bonfire will just burn until it runs out of fuel. A house fire will quickly turn into an inferno. Forest fires are hopefully like nothing you’ve ever seen—the sheer power of them is staggering.

A very recent (Oregon) fire was so bad it was creating its own weather system.

"Normally the weather predicts what the fire will do. In this case, the fire is predicting what the weather will do."

The moat won’t work as well as you probably think. A lot of the problem comes from the sky raining down embers on flammable roofs and such...

A moat is not a horrid idea. When Paradise was burning I was thinking if I lived in a fire prone envionment; I would have sprinklers on roof of my home. It would be a simple 1/2" copper pipe feeding a few sprinkler heads on the roof. Maybe a few mercury switches placed around the property, or remotely controlled through the phone line, wifi, or sat phone enabled? Nothing too elaborate. It wouldn't protect everyone. I…

I think getting rid of firefighters and installing hoses on your roof is probably not the idea of the century. Do you suppose its the asphalt catching on fire?

Houses burn (usually) because they have vented attics that embers can blow into. Fire screening your attic or not using vented attics altogether, along with concrete and masonry construction and reasonable vegetation management go a long way toward protecting structures but the fact that structures are there in the first place is the problem.

You can't take an ecosystem based on periodic fire cycles and turn it into a suburb and expect everything to continue to work. Forests need to burn a little bit all the time or they will burn a lot all at once.

> I think there should be a re-evaluation of whether or not to let people build or rebuild in especially fire-prone areas. This is already happening, not by government, but rather by the insurance markets. My friend has lived in a fire-prone area of Southern California for years. His home owners insurances rates have more than tripled in the last few years. He just recently moved (yep, Idaho).

Does the government subsidize fire insurance? I'm always taken aback when I see people rebuilding from a hurricane with subsidized wind and flood insurance. I understand why its nice for those that need it but has perverse incentives.

It does, although indirectly, through municipal fire departments. It's not "insurance" in the strict sense of the word, but it is an abatement mechanism designed to help minimize losses that would otherwise be borne by private insurers.

And they just evacuated the entire town of South Lake Tahoe. I hope the town survives. https://www.tahoedailytribune.com/news/more-evacuation-order... https://www.tahoedailytribune.com/news/lake-tahoe-residents-... https://www.sfgate.com/california-wildfires/article/Caldor-F...

Is it really? We got into this mess because we'd initially assumed that wildfires were "bad" and that we needed to stop ALL of them. However, we later found out just how beneficial small fires can be for the long-term health of a forest. If we can actually allocate funds and people towards this, it won't be an issue anymore.

I see it as a concern because (1) a large portion of wild lands are burning within a short span of time. I would guess (no evidence, just a hunch) that burning was more dispersed in time before modern fire prevention. I also feel that (2) climate change makes these fires much worse, and forests will have a much harder time rebounding.

Don't hold me to it, but I seem to remember seeing a study showing that prehistoric California had roughly 10x the current burn acreage.

I’ve been in small wildfires before. But yesterday I saw the Caldor fire from a plane… And the shear size of it was shocking. Photos and news clips don’t do the scale justice.

Is there an argument to be made for just letting the fires burn? Don't the fires have a positive effect on the soil?

They do. Many species of conifer seed don't even begin to germinate until exposed to the heat of a wildfire. Fire's are a part of the natural lifecycle of a west coast forest. Unfortunately the over suppression of fires over the last 120 years has over fueled these forests and we are witnessing the consequences now.

In some areas too much fuel has accumulated, causing fires to burn so hot that they kill the trees and destroy the seeds. After that it can take many years for the forest to recover.

Can anyone explain this? "So early on, Newsom identified some key wildfire prevention projects, and that includes things like forest thinning and prescribed burns, and they were meant to protect some of the most vulnerable communities in California. And he claimed 90,000 acres were treated, but we found that's not true. The state's own data shows that, in reality, it was less than 12,000 acres, so just a fraction of…

"we also found that the state's fire prevention work overall dropped by half last year" that is utterly not true by any stretch of the words .. it is literally political theater hit piece. see for yourselves... https://www.gov.ca.gov/2021/04/13/governor-newsom-signs-land... https://fmtf.fire.ca.gov/press-publications/ the claim is that a particular State of Calif, Dept of Forestry perhaps, program was supposed to thi…

What are you talking about, my god.

Why not make it clear that people building structures in fire-prone areas are on their own, and should design appropriately?

I'm not sure there's an appropriate design for something to survive a major forest fire.

Although that said, this article goes into how they defended the Sierra-at-Tahoe resort buildings: https://www.sfchronicle.com/bayarea/article/Sierra-at-Tahoe-...

Spoiler: it turns out that if you have a multi-million dollar insurance policy, the insurance company sends over guys to spray everything with fire retardant gel.
