When the Antiplanner looks at before-and-after aerial photos of the fire in Paradise, California that killed at least 84 people, the first thing I think is that, like last year’s Santa Rosa fire, the houses were built too closely together. This made it impossible, short of building a home exclusively of concrete, to defend homes from fire. Once one house caught on fire, its neighbors would be ignited by the radiant heat of the first.
As described in a Los Angeles Time article, the best way to prevent such “structure to structure ignition” is to build homes at least 100 feet apart. California law in fact requires that homeowners provide a 100-foot perimeter of “defensible space,” but the law doesn’t require that homes be built 100 feet apart. As the Times notes, the “100-foot requirement stops at the property line.”
Unfortunately, urban planners’ mania for density makes it difficult, if not impossible, for California developers to lay out homesites on one-acre lots, which would insure at least 100 feet between homes. While I don’t know the situation in Paradise, population data indicate that much of the growth of the city has been since 1970, when many California cities and counties began limiting low-density development.
Even for homes and businesses that were built further apart, before-and-after pictures suggest that few were paying any attention to the 100-foot defensible space requirement. The town’s buildings are swamped with trees and other vegetation growing up against and overhanging most structures.

The problems with structures were compounded by the city’s decision to put one of the main evacuation routes from the town on a “road diet,” reducing the number of lanes from four to two, sometimes with a center left-turn lane. Parking strips that could have been used to evacuate vehicles were also sabotaged by adding concrete bumpouts to encourage pedestrian crossings. At least some of the dead are people who died in their cars while stuck in traffic trying to escape the fire.
The mayor who supported road diets on this and other roads in the city claimed that nothing could have been done to allow orderly evacuation of the 27,000 people who tried to flee the fire at once. This is cruel. The city knew in advance that fire was a major danger. Instead of preparing for it with a workable evacuation plan, it deliberately made the problem worse.
One person noted that the road diet came about because the state offered to repave the road if the city reduced the number of lanes. Local officials agreed, despite opposition from residents, so they could get “free” state dollars.
Government planners claim to be able to do comprehensive planning. But the reality is that cities are too complicated to plan, so they often focus on the wrong things. In California, that usually means on anti-automobile programs, including dense housing and road diets, to the exclusion of all else. In Paradise, that mentality probably contributed to the deaths of many people.
Lived in Chico in the 90s and visited Paradise several times. It was clear due to lack of defensible space and the fact that the town was built in a pine forest that a disaster was a matter of when, not if.
Radiative heat as a cause of home ignition is irrelevant more than several meters from a structure (https://www.fpl.fs.fed.us/documnts/pdf1992/tran92c.pdf). Post-fire drone imagery shows burned homes surrounded by green trees and shrubs. Most homes were likely ignited from the air by firebrands. Under these circumstances, the 100-foot perimeter around a house matters less than the home’s resistance to aerial ignition sources.
Government-regulated electrical utilities are igniting many of California’s most destructive fires. On the one hand, regulators are under consumer pressure to keep rates low. On the other hand, utility executive are under stockholder pressure to keep costs low. On the third hand, politicians bail out utilities when the shit hits the fan. If the telephone utility industry can be deregulated, why not the electrical utility industry?
Will Paradise be the tipping point for California’s home insurance carriers, e.g., redlining of fire-prone communities? Probably not as the legislature will make sure that everyone shares the cost for the foolish (and often uninformed) decisions of those who chose to build and live in fire plains.
Needless to say, Camp Fire’s lessons have nothing to teach about landscape-level vegetation policy and practices, except that everything burns in a Mediterranean climate.
There are many a material that can help wood withstand fires.
Behold the wildfires aren’t the result of the Earth’s temp rising a degree. California’s wildfires are the result of three things, it’s land management practices and water management and environmental policy are what exacerbated the fire problem. Fire has always been a circumstance in Mediterranean climate regions. It’s part of the regenerative ecology that keeps invasive weeds out of the ecosystem, it also recycles nutrients back into the soil that could not be obtained in other ways (Unlike moister, temparate or tropical forests plant matter biodegrades slowly in dryer and mesic forests, fire is the only way they can recycle nutrients. While we think of Mediterranean as “Europe” the word in ecology encompasses a broader geographic region. Generally located between 30 and 43 degrees latitude North/South, Situated below the cool wet oceanic influenced climates of Pacific Northwest or Great Britain and Above the equatorial dry regions. Vegetation is very bushy and human height, short and seldom do trees grow above 50 feet. It’s perfect beach and bum weather.
For the last 100 years, the big cities and agriculture business have pulled water from the Colorado river, diverted other rivers, dug the Sierra Nevada mountains and sub surface wells and springs which have been tapped to accommodate domestic water consumption so LA County, San Diego residents and suburbanites can have imported jungle plants in a xeric climate; Palm trees, paradise plants, tree ferns and of course Lawn grass. Combine a drastic reduction in the natural ground water, the replacement of native vegetation with weedy, invasive (and oil rich plants like Eucalyptus) you have a recipe for disaster. So the subsurface water has been depleted; California’s forests have lost significant ground water they often depend on for the summer season; soil moisture has heavily declined, the plants thus have less and less seasonal reserves so they dry up or die mid summer after sprouting heavily during the otherwise short winter/spring rain; making them perfect kindling.
Add onto that, the federal and state government, 57% of the states forests owned by the feds. Both federal and state regulators were making it more and more difficult for loggers and forestry experts to do their jobs to depreciate the fire hazards. As a result, timber industry and subsequent employment gradually collapsed. Timber permits grew in cost, people who felled trees and planted them for a living looked for work elsewhere. Plus forestry workers who’d otherwise set prescribed fires or contract to extract dead wood (unlike wood in the Eastern US, they biodegrade at a much slower rate thanks to the dryness) were hogtied by regulation. Combustible fuel material built and built to a level, that ultimately a catastrophic blaze was inevitable.
California’s environmental policies lent it’s contributions to the triad. The state spends 10 times more money subsidizing electric cars than clearing flammable brush. California’s energy policy and air quality laws also played their part. Prior, wood waste like twigs, branches and leaves/needles unusable for timber were burned as a fuel source for electric power; Since it was a renewable resource, burning it for power seemed like the wise option however while burning wood is cleaner than coal per pound, it’s energy density is inferior and thus more had to be burned; wood is also not as clean as natural gas. Once prevalent in the state, when the state and feds started enforcing stricter air pollution laws regarding burning wood waste, the need to extract it also declined. Also by the 90’s onward, the state started subsidizing renewable power, namely solar and wind to the tune of billions, the price of electricity from these sources was artificially deflated to the point that solar power and wind power replaced wood burning plants as a source of electricity and with it the need for wood fuel collapsed. With no need to consume tree waste for fuel and the demand for timber satiated by imports, there was no demand to extract wood and the available fuel grew in volume, instead of burning safely in power plants the fuel now burns horribly in the wild. The policies enacted reduce the economic value of the forest to zero. And, with no intrinsic worth remaining, interest in maintaining the forest declined, and with it, financial resources to reduce the fuel load. And Now, it’s all burning up in one go.
This is nothing to do with Density, Las Vegas is dense, Phoenix is dense, San Diego is Dense, San Francisco is dense…..It’s the consequence of a government that ignores the limits nature sets on itself. Resource “A” i.e. Wood is safe to have in any approximation, provided Resource “B”, i.e. WATER is abundant and within reach. Which in dry southern California it is NOT. But like I’ve said before the way we govern in the US requires a true crisis mode or some sort of major disaster for people to care enough to act. So expect more houses and acres to burn until California decides what priorities are essential. Having Tesla’s on our highways or keeping houses from going up in smoke. I don’t know how much CO2 is saved driving a Tesla over a Toyota, but I can probably guess 10 million acres of wood going up in flames more than makes up for it.
