Risk Overview
Overall natural disaster risk in Sandusky County is low, with a National Risk Index score of 56.7 out of 100 — placing it in the 57th national percentile and below the national average for natural-disaster risk. 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 hail (ice stones from severe thunderstorms that damage property and crops) at Medium risk — $965K in expected annual loss and about 3.31 events per year; ice storm (freezing rain that coats surfaces in heavy, damaging ice) at Medium risk — $446K in expected annual loss and about 1.08 events per year; and winter weather (heavy snow, blizzards, and hazardous winter conditions) at Medium risk — $202K in expected annual loss and about 9.11 events per year. Across all hazards, FEMA estimates $20M in expected annual loss for a population of 59K.
Beyond physical exposure, Sandusky County has a 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: Sandusky County has received 13 federal disaster declarations since 1969, including 5 for severe storm events and 2 for biological events. The most recent was Covid-19 Pandemic (biological), declared in March 2020.
Among 88 Ohio counties, Sandusky County ranks #45 for overall natural disaster risk.
