Natural Disaster Risk in Coupeville

Natural Hazard Profile: Coupeville, Washington

Located in the Pacific Northwest in Island County, Coupeville is a town of roughly 7,656 residents. The oceanic climate that characterizes this part of Washington — marked by mild, rainy winters west of the Cascades and semi-arid conditions to the east — directly influences the types and severity of natural hazards present, making Coupeville a community where hazard awareness has real practical value.

FEMA rates Coupeville's composite natural disaster risk at 5.7 out of 10 — moderate risk. Landslide and debris flow risk tops the local hazard profile, with steep terrain and periodic heavy rainfall creating conditions for rapid slope failure in vulnerable areas. Residents should also account for tsunami and volcano risk in their preparedness planning.

Relative to other U.S. communities, Coupeville's natural disaster risk is above the U.S. national average of 4.5/10, near the 5.8/10 state average. The hazard distribution here is led by landslide and tsunami, as measured by FEMA across Island County. While city-specific sub-county variation exists, these scores represent the best available federal risk estimate.

With a moderate risk rating, Coupeville residents are well-served by maintaining standard preparedness practices — an emergency supply kit, awareness of local hazard seasonality, and insurance that covers the top local risks. Periodic review of coverage for landslide is recommended.
