When designing and installing a firewise landscape, consider the following:
o Local area fire history.
o
Site location and overall terrain.
o
Prevailing winds and seasonal weather.
o
Property contours and boundaries.
o
Native vegetation.
o
Plant characteristics and placement (duffage, water
and salt retention ability, aromatic oils, fuelload per area, and size).
o
Irrigation requirements.
To create a firewise landscape, remember that the primary goal is fuel
reduction. To this end, initiate the zone concept. Zone 1 is closest to the structure; Zones 2-4 move progressively further
away.
Zone 1. This well-irrigated area encircles the structure for at least 30' on all sides, providing
space for fire suppression equipment in the event of an emergency. Plantings should be limited to
carefully spaced low flammability species.
Zone 2. Low flammability plant materials should be used here. Plants should be low-growing,and the irrigation
system should extend into this section.
Zone 3. Place low-growing
plants and well-spaced trees in this area, remembering to keep the volume of vegetation (fuel) low.
Zone 4. This furthest zone from the structure is a natural
area. Selectively prune and thin all plants and remove highly flammable vegetation.
