California Gov. Gavin Newsom has announced that permitting will be streamlined for anyone rebuilding a home after the LA fires. For some reason conservatives are taking a weird victory lap over this, which is kind of crazy. Have they ever paid attention to a natural disaster in California before? Permitting is always streamlined. And for homes near the coast, the enabling act for the Coastal Commission has always said no permission is needed as long as you rebuild to about the same size as the house that was destroyed.
So there's nothing to this. But I still need to be a spoilsport. There's no way we're going to stop people from rebuilding in fire prone areas, but there's something we can do: insist that new homes be hardened against fire.

Here's the thing: In fires like the ones in LA, most of the damage is caused by showers of burning embers that are blown into neighborhoods by strong winds and then spread from there. These embers can travel a mile or more, so clearing brush at the wildland-urban interface won't do much when winds are as heavy as they were last week. The only thing that works is hardening every house within a mile or two. This includes things like fire-retardant roofs and siding, automatic sprinkler systems, cleared zones around property lines, and so forth. And it has to be done universally for it to be effective.
So yes to streamlining rebuilding permits, but with one exception: every house has to be rebuilt to fire-hardening standards. This costs money and won't be popular, and for that reason it probably won't get done. But it's the only real answer. If we ignore it, this will happen all over again no matter how many airplanes we buy or how big our reservoirs are.
The LA Times ran a good piece about this a few days ago based on interviews with Jack Cohen and Stephen Pyne, a pair of experts on urban fires. Here's an excerpt:
“The assumption is continually made that it’s the big flames” that cause widespread community destruction, [Cohen] said, “and yet the wildfire actually only initiates community ignitions largely with lofted burning embers.”
Experts attribute widespread devastation to wind-driven embers igniting spot fires two to three miles ahead of the established fire. Maps of the Eaton fire show seemingly random ignitions across Altadena.
“When you study the destruction in Pacific Palisades and Altadena, note what didn’t burn — unconsumed tree canopies adjacent to totally destroyed homes,” he said. “The sequence of destruction is commonly assumed to occur in some kind of organized spreading flame front — a tsunami of super-heated gases — but it doesn’t happen that way.”
“In high-density development, scattered burning homes spread to their neighbors and so on. Ignitions downwind and across streets are typically from showers of burning embers from burning structures.”
....The 1991 Tunnel fire in the Oakland and Berkeley Hills marked the start of the modern era of urban fires, destroying 2,843 homes. More recently, fires devastated Gatlinburg, Tenn., in 2016, the towns of Superior and Louisville in Colorado in 2021 and Lahaina, Hawaii, two years ago.
“It’s not just a California quirk,” Pyne said. “California, I think, gets there first in exaggerated forms, but this is a national issue. And, in fact, it’s becoming an international issue.”
....“We don’t necessarily need a trillion-dollar program and a fire czar to get control of the fire problem,” Pyne said. “What we need are a thousand things that tweak the environment in favorable ways such that we can prevent these eruptions.” For example, municipal and fire prevention agencies must give property owners advance — and continual — warnings to clear dead vegetation and to wet dry brush within 10 feet of the house with periodic, prolonged sprinklings.
