Add fire mortality, cause, and loss

Natural hazard exposure is only part of the risk. Fire deaths and injuries, cause of ignition, and dollar loss per incident come from NERIS incident reporting, which grows as departments serving Tuolumne County enroll. Our Regional tier adds that data for the departments your jurisdiction sponsors, next to public risk and NERIS adoption for every department in Tuolumne County.

Department Rankings

Fire and EMS departments serving Tuolumne 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.
