ZONE THEORY
1: Garden Zone
2: Fuel break
3: Transition Zone
4: Natural Zone
ZONE 1: GARDEN ZONE• Distance = 30 ft. from home & structures
• Goals:• Withstand flying embers• Survive temperatures 900°F – 1300°F• A place to fight the fire
• Planting Recommendations:• Broad leaves• Supple / moist• Beauty and recreation
ZONE 2: GREEN BELT / FUEL BREAK• Distance = 31 - 70 ft. from structures
+ 10 ft. for every 10% increase in slope
• Goals:• Reduce vertical fuels• Should stop a ground fire
• Planting Recommendations:• Plants should be ≤ 18”• Driveways kept clear• Low growth, fuel, and maintenance• Screens/windbreaks kept isolated from other
large plants
ZONE 3: TRANSITION ZONE• Distance = 71 - 120 ft. from structures
+ 10 ft. for every 10% increase in slope
• Goals:• Should dramatically slow a fire
• Planting Recommendations:• Create barriers• Control erosion• Enhance wildlife presence
ZONE 4: NATURAL ZONE• Distance = 121 ft. and beyond
+ 10 ft. for every 10% increase in slope
• Goals:• Reduce severity of a fire• Ensure landscape is safe to neighbors• Maintain ecological integrity
• Recommendations:• Prescribed fire• Mechanical veg treatment
DESIGN PRINCIPLES
DESIGN PRINCIPLES
I. Keep it Simple• A low maintenance landscape remains effective
II. Entrances & Exits• Need ease of access• Readily identifiable – at least 6 ft wide• Ideal ground surfaces: concrete, wood, crushed rock, compacted earth
III. Islands, not Lines• Breaks up vegetation and fuels
IV. Patient Planting• Don’t plant in dense quantities – think of mature plant sizes
DEFENSIBLE SPACE
Landscape Type 0 – 20% 21 – 40% ≥ 41%
Herbaceous w/ some shrubs 30 ft 100 ft 100 ft
Shrubs 100 ft 200 ft 200 ft
Trees w/o understory 30 ft 100 ft 200 ft
PLANTS FOR HILLS• Plant fuels should be kept to a minimum
• Best Plants to use = produce little fuel , low growing , easy to maintain
• Avoid shrubs with twiggy interiors & produce a lot of litter & seeds
• Shrubs > 18” not recommended
• Choose ground-hugging plants• Slows erosion• Slows growth of weeds
