Risk Overview

About Natural Disaster Risk in Kittitas County, Washington

Kittitas County manages relatively moderate risk

Kittitas County's composite risk score of 89.12 ranks in the "Relatively Moderate" category, above the national average but not extreme. The score reflects a unique hazard mix: catastrophic wildfire risk paired with significant earthquake and flood threats.

Mid-range risk profile for Washington

Kittitas County scores 89.12 against Washington's average of 70.01, placing it among the state's higher-risk counties. This elevated score is driven primarily by wildfire exposure in this transition zone between Puget Sound and the drier interior.

Kittitas shares risk with surrounding counties

Kittitas County (89.12) sits between Lewis County (89.69) to the southwest and Okanogan County (89.19) to the north, forming a band of elevated wildfire and earthquake risk across central Washington. All three counties face similar seismic threats and water-related hazards.

Wildfire, earthquake, and flood threats

Kittitas County faces extreme wildfire risk (99.68), the highest among its major hazards, affecting thousands of homes in forested and semi-arid zones. Earthquakes (93.86) and flooding (74.78) pose secondary but serious threats, while tornadoes (7.41) are rare.

Wildfire, earthquake, and flood preparation

Kittitas County residents must combine wildfire defensibility with earthquake and flood insurance: clear vegetation from home perimeters, install metal roofing if possible, and secure separate earthquake and flood policies. Properties near waterways or in forest-interface zones face compounded risks requiring comprehensive coverage.

Risk Verdict

Kittitas County registers a moderately elevated natural disaster risk, ranking at the 89th percentile across all U.S. counties. High composite risk signals that multiple hazard types are elevated simultaneously; planning for more than one scenario is important in Kittitas County.

Hazard Breakdown

Wildfire risk is Kittitas County's dominant natural hazard, ranked at the 100th percentile nationally under FEMA's National Risk Index. Earthquake ranks second at the 94th percentile nationally. Additional tracked hazards include flood (75th percentile), tornado (7th percentile).

Preparedness Context

Wildfire ranks as Kittitas County's primary hazard at the 100th percentile nationally. For Kittitas County households in high-WUI areas, go-bag readiness — the ability to leave within 15 minutes — is more important than shelter-in-place planning for most residential properties. Alongside wildfire, earthquake at the 94th percentile nationally means a multi-season preparedness mindset — fire season and flood or storm season often require different household plans. Kittitas County county's local emergency management office publishes community-specific wildfire risk assessments and evacuation zone maps; households should review their zone assignment and sign up for zone-specific alerts.

Regional Context

Kittitas County falls 19.1 points above Washington's typical county risk level, which means the hazard environment here is notably more demanding than the state baseline.
