Risk Overview

FEMA's National Risk Index rates Wabaunsee County at very low composite risk, with a National Risk Index score of 14.6 out of 100 — placing it in the 15th national percentile and among the lowest-risk counties in the country. The score blends Expected Annual Loss, Social Vulnerability, and Community Resilience across all 18 FEMA hazard types.

The county's risk is driven primarily by wildfire (uncontrolled fires that spread across wildland and into communities) at Low risk — $1M in expected annual loss and about 0.00 events per year; landslide (downhill movement of rock, soil, and debris on unstable slopes) at Low risk — $4K in expected annual loss and about 0.30 events per year; and ice storm (freezing rain that coats surfaces in heavy, damaging ice) at Medium risk — $180K in expected annual loss and about 0.93 events per year. Across all hazards, FEMA estimates $7M in expected annual loss for a population of 7K.

Beyond physical exposure, Wabaunsee County has a low social vulnerability rating (how susceptible the population is to harm) and a high community resilience rating (its capacity to prepare for and recover from disasters). A less vulnerable population paired with strong resilience helps the community absorb and recover from events.

The federal record bears this out: Wabaunsee County has received 26 federal disaster declarations since 1967, including 17 for severe storm events and 2 for biological events. The most recent was Severe Storms, Straight-Line Winds, Tornadoes, and Flooding (severe storm), declared in June 2026.

Among 105 Kansas counties, Wabaunsee County ranks #74 for overall natural disaster risk.
