5-Source Composite Score

FEMA NRI wildfire risk, USGS 30m Wildfire Hazard Potential, NIFC historical fire perimeters, CAL FIRE FHSZ zones (CA only), and NOAA fire weather — each weighted and shown separately.

Per-Source Breakdown

Unlike single-score tools, HomeDoc shows which data source drives your risk level and how confident we are in each — including vegetation density, fire return interval, and WHP raster class.

Defensible Space & Home Hardening

Actionable recommendations for Zone 0/1/2 defensible space, ember-resistant vents, Class A roofing, and fire-resistant landscaping — matched to your risk level.

How It Works

Address → County FIPS

Your address geocodes to a county FIPS code used across all 5 data source queries.

Five Sources Queried in Parallel

FEMA NRI, USGS WHP raster, NIFC fire perimeters, NOAA fire weather, and (for California) CAL FIRE FHSZ — all fetched simultaneously and cached 90 days.

Weighted Composite Computed

Each source is normalized to 0–100, weighted by data quality, and combined into an overall score with per-source confidence shown.
