Risk Overview

About Natural Disaster Risk in Sedgwick County, Kansas

Sedgwick County faces highest national risks

Sedgwick County scores 96.60 on the composite risk scale, ranking in the "Relatively High" category and substantially exceeding the national average. The county faces extreme exposure across flood (96.09), tornado (99.27), and wildfire (94.43) hazards.

Kansas's highest-risk county

At 96.60, Sedgwick County has the highest composite risk score in Kansas, more than triple the state average of 29.89. This singular elevation reflects the county's exceptional vulnerability to multiple catastrophic natural hazards.

Dramatically higher risk than neighbors

Sedgwick County's 96.60 score vastly exceeds all neighboring counties, including Saline County (66.16) and Seward County (42.30). The county stands alone in Kansas as a high-risk disaster zone.

Tornado, flood, and wildfire triple threat

Tornado risk reaches a near-maximum 99.27, flood risk hits 96.09, and wildfire risk scores 94.43—making Sedgwick County vulnerable to three catastrophic hazard types simultaneously. Even earthquake risk of 75.22 significantly exceeds most Kansas counties.

Comprehensive insurance is essential

Sedgwick County homeowners must carry robust wind and tornado coverage, comprehensive flood insurance, and wildfire protection—this is not optional given the county's extreme multi-hazard exposure. Consider a safe room or storm shelter installation and maintain detailed property inventory for all disaster types.

Additional tracked hazards include wildfire (94th percentile), earthquake (75th percentile), hurricane (43th percentile).

Preparedness Context

Ranked at the 99th percentile nationally for tornado risk, Sedgwick County is in a zone where storm shelters have the highest per-dollar protective value of any mitigation investment.

How is natural disaster risk measured?
FEMA's National Risk Index (NRI) calculates risk scores for 18 natural hazard types across all U.S. counties and census tracts. The composite score combines Expected Annual Loss (estimated dollar losses from each hazard), Social Vulnerability (demographic factors affecting disaster impact), and Community Resilience (ability to recover). Percentile scores rank each county against all 3,144 U.S. counties, and risk ratings range from Very Low to Very High.
Why is Sedgwick County higher risk than average?
Sedgwick County's composite risk score of 97th percentile is above the Kansas state average of 30th percentile. This elevated risk is driven by tornado exposure (99th percentile), along with flooding and wildfire and earthquake risk.
