Risk Overview

About Natural Disaster Risk in Custer County, Colorado

Custer County ranks among nation's safest

Custer's composite risk score of 3.91 places it in the very low category, making it one of the safest counties in America. Despite mountain terrain, the county faces minimal natural disaster risk.

Exceptionally low risk for Colorado

Custer's 3.91 score is well below Colorado's 40.67 state average, ranking it in the state's bottom tier for disaster exposure. Residents enjoy significantly lower risk than typical Coloradans.

Safest county in south-central mountains

Custer (3.91) rivals Cheyenne and Crowley as Colorado's safest counties, despite its mountain setting. Its isolation and sparse population reduce exposure compared to more developed neighboring counties.

Wildfire presents the main exposure

Custer's wildfire risk of 81.62 is its highest score, though still far below the county's minimal overall risk rating. Flood, tornado, and earthquake risks all remain negligible.

Basic homeowners coverage is typically sufficient

Standard policies cover your exposures effectively in this low-risk county. Review wildfire coverage for properties near forested areas and maintain basic defensible space as a simple precaution.
