Risk Overview
Overall natural disaster risk in Kent County is medium, with a National Risk Index score of 92.2 out of 100 — placing it in the 92nd national percentile and near the national midpoint for natural-disaster risk. The score blends Expected Annual Loss, Social Vulnerability, and Community Resilience across all 18 FEMA hazard types.
Most of Kent County's expected losses come from strong wind (damaging straight-line winds outside of tornadoes and hurricanes) at Very High risk — $10M in expected annual loss and about 2.84 events per year; tornado (violently rotating columns of air capable of catastrophic local damage) at High risk — $28M in expected annual loss and about 0.30 events per year; and winter weather (heavy snow, blizzards, and hazardous winter conditions) at High risk — $950K in expected annual loss and about 24.54 events per year. Across all hazards, FEMA estimates $147M in expected annual loss for a population of 658K.
Beyond physical exposure, Kent County has a very low social vulnerability rating (how susceptible the population is to harm) and a very 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: Kent County has received 13 federal disaster declarations since 1965, including 3 for flood events and 3 for severe storm events. The most recent was Severe Storms, Tornadoes, and Flooding (flood), declared in February 2024.
Among 83 Michigan counties, Kent County ranks #5 for overall natural disaster risk.
