About Natural Disaster Risk in Kootenai County, Idaho

Kootenai County faces moderate national hazard exposure

With a composite score of 78.98 and "Relatively Low" rating, Kootenai County sits at the higher end of moderate risk nationally. The county's diverse hazard profile—flood, wildfire, earthquake, and tornado—creates layered vulnerability.

Kootenai County ranks as Idaho's highest-risk area

At 78.98, Kootenai County nearly doubles the state average of 38.51, positioning it as the single highest-risk county in Idaho. This elevation reflects the county's geographic exposure across multiple disaster types.

Kootenai County far exceeds nearby counties

Kootenai County's 78.98 vastly outpaces Latah County (33.27) and Lewis County (3.09), making it a clear outlier in northern Idaho. The county's unique risk profile distinguishes it significantly from surrounding areas.

Flood, wildfire, and earthquake all threaten residents

Comprehensive coverage is essential for safety

Homeowners should carry flood insurance, wildfire coverage, and earthquake protection given Kootenai County's multiple hazard exposures. Standard policies cover none of these; work with an agent to close all gaps before disaster strikes.

Risk Advisory: Kootenai County

Risk Verdict

Kootenai County's FEMA risk score places it at the 79th percentile nationally, indicating lower-than-typical exposure for a U.S. county. At this risk level, having a documented household preparedness plan — not just awareness — is the meaningful next step for Kootenai County residents.

Hazard Breakdown

Flood risk is Kootenai County's dominant natural hazard, ranked at the 86th percentile nationally under FEMA's National Risk Index. Wildfire ranks second at the 80th percentile nationally. Additional tracked hazards include earthquake (79th percentile), tornado (22th percentile).

Preparedness Context

At the 86th percentile nationally for flood risk, Kootenai County residents benefit from understanding their specific flood zone status. Even one inch of floodwater causes significant structural damage to properties outside officially designated high-risk zones. Secondary wildfire exposure at the 80th percentile adds a second preparedness layer; households should review coverage options and alert sign-up for both hazard types. A tested family preparedness plan specific to Kootenai County's primary hazards — including how to shelter in place or evacuate, and who to call — provides more real protection than a general emergency kit sitting unused on a shelf.

Regional Context

The Idaho county average is 40.5 composite points below Kootenai County's score, a gap that reflects the county's elevated position in the state's hazard distribution.
