Wildfire Risk Assessment Calculator

Evaluate property wildfire risk and get mitigation recommendations based on multiple risk factors

Assess Wildfire Risk Factors

Moderate tree density with varied species

Moderate fire spread rate

Minimum 100 feet recommended

Higher wind = higher risk

Lower humidity = higher risk

Higher temp = higher risk

More days = higher risk

Fire-resistant materials reduce risk

Non-combustible is safest

20+ feet for fire trucks

Reliable water access critical

Greater distance = lower risk

Mitigation Recommendations

1

Create fuel breaks and thin vegetation around property

2

Remove dead or dying vegetation regularly

Risk Analysis

MODERATE RISK: Enhanced fire safety measures recommended. Implement mitigation strategies to reduce risk levels.
💡 Tip: Defensible space of 100 feet is adequate. Maintain clear zones regularly.

Understanding Wildfire Risk Assessment

How Risk is Calculated

This calculator uses a weighted scoring system based on six major risk factors. Each factor is scored from 1-10 (higher = more risk) and weighted by importance:

  • Weather Conditions (25%): Wind, humidity, temperature, drought
  • Vegetation (20%): Type and density of surrounding plants
  • Defensible Space (20%): Clear zones around structures
  • Terrain (15%): Slope and topographical features
  • Structure Materials (10%): Fire-resistant building materials
  • Access & Water (10%): Emergency response capability

Why This Matters

Wildfire risk assessment helps property owners understand their vulnerability and prioritize mitigation efforts. Even small improvements can significantly reduce risk:

Key Statistics:

  • • 85% of wildfires are human-caused
  • • Creating 100 ft defensible space can increase survival rate by 85%
  • • Metal roofing reduces ignition risk by 90%
  • • Properties with fire-resistant landscaping are 40% more likely to survive

Note: This assessment is for general guidance only. Consult with local fire authorities and follow official wildfire preparedness recommendations for your area.
