100' Defensible Space

Why 100 Feet ?

Following these simple steps can dramatically increase the chance of your home surviving a wildfire!

A Defensible Space of 100 feet around your home is required by law. The goal is to protect your home while providing a safe area for firefighters.

“Lean, Clean and Green Zone.”

– Clearing an area of 30 feet immediately surrounding your home is critical. This area requires the greatest reduction in flammable vegetation.

“Reduced Fuel Zone.”

– The fuel reduction zone in the remaining 70 feet (or to property line) will depend on the steepness of your property and the vegetation.

Spacing between plants improves the chance of stopping a wildfire before it destroys your home. You have two options in this area:

TreeCreate horizontal and vertical spacing between plants. The amount of space will depend on how steep the slope is and the size of the plants.

TreeLarge trees do not have to be cut and removed as long as all of the plants beneath them are removed. This eliminates a vertical “fire ladder.”

When clearing vegetation, use care when operating equipment such as lawnmowers. One small spark may start a fire; a string trimmer is much safer.

Remove all build – up of needles and leaves from your roof and gutters. Keep tree limbs trimmed at least 10 feet from any chimneys and remove dead limbs that hang over your home or garage. The law also requires a screen over your chimney outlet of not more than 1/2 inch mesh.

Some fire department jurisdictions may have additional requirements. Some removal activities may require special procedures for 1) threatened and endangered species, 2) avoiding erosion conditions, and 3) protection of water quality. The area to be firesafe treated does not extend beyond your property. Contact the local CDF office for more details.
