Natural Hazard Loss Profile
Expected annual loss across the 18 natural hazards in FEMA's National Risk Index. Life safety is expressed in fatality-equivalents, combining expected deaths and injuries. Property loss counts building damage only, not agriculture.
These figures cover natural hazards only. Structure fire, EMS, and motor vehicle incidents are not in the National Risk Index, so this is not an all-cause life safety measure. For Snohomish County, the largest single contributor is Earthquake, 59% of the life-safety total.
Snohomish County carries an expected 11 natural hazard fatality-equivalents and $279.2M in building loss per year. Rank chips compare the 39 Washington counties. Nationally, Snohomish County ranks 35th of 3,222 U.S. counties for life-safety loss, 1321st for life safety per 100k residents, 49th for property loss, and 1633rd for property loss per resident. Computed from census tract data covering every resident, independent of fire department boundaries.
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 Snohomish 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 Snohomish County.

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.
