What is the 10 a.m. rule? Controversial firefighting strategy could be back

Full suppression by 10 a.m. has not been reinstated under Trump but political pressure remains

Look, I want to walk you through something that's been heating up in the wildfire policy world, and it matters for all of us out here. According to CalMatters Housing, there's been renewed political pressure around something called the "10 a.m. rule," an old Forest Service mandate from 1933 that required all wildfires to be extinguished by 10 a.m. the day after being reported. The rule was born out of the agency's desire to demonstrate control after the devastating Big Burn of 1910, which torched millions of acres and destroyed entire towns. It became foundational to how we think about fighting fire in this country.

Here's where it gets interesting though. Over the decades, fire researchers realized that aggressively suppressing every single fire actually created a serious problem. By putting out all fires immediately, dead timber accumulated on forest floors. When fires inevitably did spread, they burned hotter and faster than they would have in a landscape that experienced periodic, smaller burns. Scientists called this the "Wildfire Paradox." The Forest Service eventually modified the rule in 1971 and officially abandoned it in 1978, moving toward more nuanced approaches that allowed some fires to burn in remote areas to reduce fuel loads.

But recently, political winds have shifted back toward aggressive suppression. According to CalMatters, President Trump issued an executive order last June focused on wildfire response, and draft versions of federal policy actually included returning to something like the 10 a.m. rule. Similar language appeared in draft versions of the Fix Our Forests Act. These proposals faced pushback from wildfire advocates who argued that locking in mandatory full suppression could be dangerous and counterproductive.

The good news is that advocacy groups were able to get the explicit 10 a.m. language removed from the legislation. However, the Forest Service Chief recently told Congress that his agency remains committed to aggressive initial attack on all wildfires this year, emphasizing that "every fire has a full-suppression strategy." So while the old policy didn't come back officially, the underlying philosophy of aggressive suppression appears to be getting renewed emphasis at the federal level.

What I am seeing locally is that this tension between suppression and more strategic fire management is going to continue influencing how we plan development, especially in our wildland-urban interface areas here in the East Bay and around Fremont. Property owners and developers need to understand that federal fire policy is in flux, and that affects everything from insurance costs to building standards to evacuation planning. The real estate market responds to these shifts, and it's worth paying attention to which way the political winds are blowing on fire management.
