Risk Overview

About Natural Disaster Risk in Brewster County, Texas

Brewster sits well below national disaster risk

Brewster County's composite risk score of 21.06 earns a Very Low rating and sits 57% below the national average. This remote West Texas county enjoys comparatively low exposure to natural disasters nationwide.

Among Texas's safer counties

Brewster's 21.06 score sits 57% below the Texas state average of 49.00, placing it in the lower-risk tier statewide. Its remote location shields it from many hazards affecting more populated regions.

Safer than most regional counterparts

Brewster (21.06) outperforms nearby Borden (5.69) only slightly but substantially beats Bowie (79.01) and Brazoria (93.64). Its isolated Big Bend location reduces exposure compared to more accessible counties.

Wildfire is the primary natural hazard

Wildfire risk of 88.68 makes this Brewster's dominant threat, reflecting the county's arid terrain and sparse vegetation. Earthquake risk (26.53) and flood risk (33.75) present secondary concerns, while tornado and hurricane threats remain minimal.

Wildfire and earthquake coverage recommended

Brewster County residents should ensure their homeowners policy includes wildfire protection and consider earthquake coverage given the county's geological setting. Defensible space around structures and evacuation planning are practical wildfire protections for this remote county.

Hazard Breakdown

Wildfire risk is Brewster County's dominant natural hazard, ranked at the 89th percentile nationally under FEMA's National Risk Index. Flood ranks second at the 34th percentile nationally. Additional tracked hazards include hurricane (28th percentile), earthquake (27th percentile), tornado (15th percentile).

Preparedness Context

Brewster County's dominant hazard is wildfire, ranked at the 89th percentile nationally. Maintaining at least 30 feet of lean, clean vegetation around structures in Brewster County and keeping gutters clear of debris significantly reduces ignition risk from wind-driven embers. The county's flood exposure at the 34th percentile nationally complements the wildfire risk — saturating rain after burn scarring often triggers secondary flood and debris flow events. Brewster County's households benefit from reviewing homeowners insurance before fire season, specifically whether the policy covers replacement cost rather than actual cash value, and whether it includes additional living expenses if displacement is required.

Regional Context

A composite score 27.9 points below the Texas state average puts Brewster County in a better-than-typical position relative to neighboring counties.
