What is the size of zone 3 for defensible space?

Zone 3 for defensible space is designated as the area that extends from 30 to 100 feet from the main structure. This zone serves as a transition area where vegetation management is crucial in reducing the risk of a fire reaching the home. In a wildfire context, this space is managed to create defensible space by thinning trees, removing dead vegetation, and ensuring proper spacing between plants.

This buffer zone is essential because it limits the intensity of a fire that reaches the edges of the property and helps to prevent firebrands from igniting combustible materials near the structure. Properly maintaining vegetation in this area can significantly reduce the chance of a fire impacting the home, making it a vital component of wildfire mitigation strategies.
