SACRAMENTO, Calif. — Reeling from destructive wildfires, including the deadliest in California history, state lawmakers in 2020 passed new requirements for clearing combustible materials like dead plants and wooden furniture within 5 feet (1.5 meters) of homes in risky areas.
The rules were set to take effect on Jan. 1, 2023. But as Los Angeles grapples with blazes that have destroyed thousands of homes in what could be the costliest natural disaster in U.S. history, the regulations still haven't been written. The state Board of Forestry and Fire Protection has no firm timeline for completing them.
''It's frustrating at every level of government,'' said Democratic state Sen. Henry Stern, who was part of a group of lawmakers who authored the legislation. ''I feel like a failure on it, being quite frank.''
Most of the neighborhoods ravaged by the Palisades Fire are in areas that must follow state requirements to keep the immediate surroundings of their homes free of combustible materials and would be subject to the new rules because they are deemed at highest fire risk by the California Department of Forestry and Fire Protection. The fire, driven by hurricane-force winds that spread embers by air, destroyed at least 5,000 structures across areas including Pacific Palisades, Malibu and Topanga Canyon.
Under the latest proposal, existing homes would have three years to comply with the regulations, so it's not clear how many homes would have been saved. But clearing the immediate area around homes likely would have made some difference, several experts said.
''We feel really strongly that it would'' have made a difference in some cases based on previous research, said Steve Hawks, a former state firefighter who now works for an insurance industry research group that supported the law. ''There's no guarantees, of course, particularly when you have a high intensity wildfire like these.''
So-called defensible space laws require homeowners in fire-prone places to keep the area immediately around their homes free of landscaping and other materials that could catch fire. California already enforces some of the most stringent defensible space laws in the West. The state began requiring homeowners in high-risk areas to clear flammable materials within 30 feet (9 meters) of their houses in the 1960s and then expanded the rules to include areas within 100 feet (30.5 meters) of structures in 2006.
The latest measure creates a new ''ember-resistant'' zone, dubbed ''zone zero,'' that bars things like brush, wooden fencing, furniture, sheds and mulch within 5 feet (1.5 meters) of homes. The idea is to clear all materials that could catch fire from flying embers carried by winds and spread to the structure. State officials and researchers said embers are responsible for 90% of structures destroyed by wildfire.
