Risk Overview
Overall natural disaster risk in Valley County is very low, with a National Risk Index score of 26.0 out of 100 — placing it in the 26th 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.
Most of Valley County's expected losses come from hail (ice stones from severe thunderstorms that damage property and crops) at High risk — $3M in expected annual loss and about 6.21 events per year; drought (extended dry periods that stress water supplies and agriculture) at Medium risk — $2M in expected annual loss and about 31.57 events per year; and strong wind (damaging straight-line winds outside of tornadoes and hurricanes) at Medium risk — $1M in expected annual loss and about 2.42 events per year. Across all hazards, FEMA estimates $9M in expected annual loss for a population of 4K.
Beyond physical exposure, Valley County has a low social vulnerability rating (how susceptible the population is to harm) and a medium community resilience rating (its capacity to prepare for and recover from disasters). Both measures sit toward the lower end, indicating relatively modest population sensitivity.
The county's disaster history tells the same story: Valley County has received 18 federal disaster declarations since 1966, including 9 for severe storm events and 4 for flood events. The most recent was Severe Storms and Straight-Line Winds (severe storm), declared in July 2022.
Among 93 Nebraska counties, Valley County ranks #37 for overall natural disaster risk.
