Primary Fuel Break or Home Ignition Zone: is the zone at least 30 feet from the home starting from the outside edge of the home’s furthest extension. This may be the edge of a roof eve or the outside edge of a deck or porch. For most homeowners, this area is the residential landscape. This often has irrigation, contains ornamental plants and is routinely maintained. If irrigated, the area should be:
• Lean - only a small amount of flammable vegetation should be present with in the 30 feet of the house
• Clean- no accumulations of dead vegetation or flammable debris with in the area.
• Green– plants located within this area are kept healthy, green and irrigated during the fire season.
Secondary Fuel Break or Wildland Fuel Reduction Area: is the area that lies beyond the primary fuel break or residential landscape area (an additional 20 to 70 feet ) and is where sagebrush, juniper and other wild plants grow. Within this area:
• Remove all dead vegetation (dead brush, dried grass and fallen branches)
• Thin out thick shrubs and trees to create a separation between them – use shaded fuel break techniques
• Remove ladder fuels by removing low tree branches and removing or pruning any shrubs under the trees
