Colorado Wildfire Hazard Profile

Hazard Data · Model Version 2.5

Overview

Colorado's wildfire hazard has increased significantly with population growth in the WUI zone along the Front Range and mountain communities. NIFC and Colorado State Forest Service data show a trend toward larger, more destructive fires. The 2021 Marshall Fire demonstrated that wind-driven grassland fires in the Front Range WUI can cause catastrophic structural losses even outside traditional forested wildfire zones.

Hazard Scoring Approach

Calchis computes a Calchis Hazard Score (0–10) for wildfire hazard at any US address. The score is composed of weighted sub-components derived from federal data sources and published research. All score components are transparent and returned in API responses.

These are hazard scores — physical intensity likelihood only. They do not include property exposure or vulnerability data. We never call a hazard score a risk score. See the full methodology for scoring details.
