Wildfire mitigation milestones — 10–20 ft High Exposure pathway

Organized to match the IBHS 10–20 ft High Exposure pathway: Ember Defense → Spread Defense → Structure Defense → Neighborhood Resilience. The milestone is the outcome; the pathway determines the task sequence. Milestones 1 and 2 are Essential; milestones 3 and 4 are Enhanced — protection to add once the essentials are in place.

Circle size is how well a measure performs for each of the four attributes: effectiveness at reducing fire risk, cost, effects on livability or quality of life, and maintenance needs. Circle color is how confident we are in that score, kept separate on purpose: a measure can look good on a dimension where our basis for saying so is thin.

What do the circle sizes mean?

Medium$3,000 to $8,000Some impactMedium needs
Low>$8,000High impactHigh needs
Insufficient evidence, not priced, or not applicable

Notes on cost

minimal cost — free, labor-only, or under $100 (neutral gray; confidence in the tooltip)

New build = materials-only increment over a traditional build (Headwaters / IBHS, Fall 2025); Retrofit = fully loaded incl. labor (Headwaters 2024). Hover a cell or open the table view for dollar figures. A whole-home retrofit runs $2,000 to $100,000+.

What do the circle colors mean?

Confidence in the assessment

High — converging lines of evidence, no meaningful dissent
Medium — evidence exists but is limited or indirect
Low — asserted in guidance, little or no evidence published

How to read one circle

bigger = better score darker = more confident hover = the evidence and dollars

Matrix of 29 wildfire mitigation measures grouped under four IBHS milestones for the 10–20 ft High Exposure pathway, assessed on five dimensions — effectiveness, new-build cost, retrofit cost, livability, and maintenance — with a short comment per measure. Circle size shows the level (for cost, the affordability tier) and circle color shows confidence in that assessment.
