For Arapahoe County, the largest single contributor is Cold Wave, 36% of the life-safety total.

Add fire mortality, cause, and loss

Natural hazard exposure is one half of the picture. The other half is what your departments run on: fire deaths and injuries, cause of ignition, dollar loss per incident. That comes from NERIS incident reporting, and it grows as departments serving Arapahoe County enroll. Our Regional tier brings it together across your jurisdiction, with participating departments, alongside response time analytics, cross-department benchmarking, and coverage gap analysis.

Department Rankings

Fire and EMS departments serving Arapahoe County. Click column headers to sort.

NRI Rating is from FEMA's National Risk Index, which measures community risk across 18 natural hazards using expected annual losses, social vulnerability, and community resilience. Life-Safety Loss uses FEMA's Value of Statistical Life ($13.7M per expected fatality) to estimate annual risk to human life.

Department boundaries and station counts are self-reported through NERIS Public and may not reflect current service areas. Population and Life-Safety Loss reflect each department's full jurisdiction. County-level risk metrics are computed from census tract data and are not affected by boundary accuracy. See full methodology.
