Buy First Responders Time By Creating a Defensible Zone 

A defensible zone or space is the area around your home in which various precautions are taken to defend your home against wildfire. Learn more about Home Ignition Zones (HIZ) below.

Immediate ZONE 1 - Extends 0-5 feet out from your house, garage and other structures

• Clean roofs and gutters of dead leaves, debris and pine needles that could catch embers.

• Reduce embers that could pass through vents in the eaves by installing 1/8” metal mesh screening.

• Clean debris from exterior attic vents and install 1/8” metal mesh screening to block embers.

• Screen or box-in areas below patios and decks with wire mesh to prevent debris and combustible materials from accumulating.

• Move any flammable material away from wall exteriors—furniture, flammable plants, leaves and needles, firewood piles—anything that can burn. Remove anything stored underneath decks or porches.

 

Intermediate ZONE 2 - Extends 30 feet out

• Remove all dead plants, grass, weeds, and dry leaves.

• Trim trees regularly to keep branches a minimum of 10 feet from other trees and structures.

• Remove branches hanging over your roof.

• Create a separation between trees, shrubs and items that could catch fire, such as patio furniture, wood piles, swing sets, etc.

Intermediate ZONE 2 - Extends 30 feet out

• Keep grass to a maximum height of 4 inches.

• Create horizontal spacing between shrubs and trees. 

• Create vertical spacing between grass, shrubs and trees. 

• Remove vegetation adjacent to storage sheds, garages, and all buildings.

• Trees 30 to 60 feet from the home should have at least 12 feet between canopy tops.

• Trees 60 to 100 feet from the home should have at least 6 feet between the canopy tops.
