Summary

Defensible space around homes can more than double structure survival rates.
Flying embers are a major cause of urban fires, spreading them erratically.
New regulations aim to create ember-resistant zones near homes.

Preventing destructive urban wildfires hinges on proactive measures in the outdoor spaces surrounding homes, according to recent research. Studies indicate that creating defensible zones free of combustible materials and fortifying homes with fire-resistant features can dramatically improve structure survival.

The complexity of urban fires, exacerbated by flying embers, makes them challenging for firefighters. These embers can ignite new fires far from the main blaze, spreading them erratically and making traditional fire breaks less effective.

As California grapples with updating building codes, new "Zone Zero" regulations are being considered to require ember-resistant zones. While these measures aim to enhance safety, some homeowners are concerned about the potential impact on greenery and neighborhood aesthetics.
