Adams County, IL: Tornado Risk and Shelter Cost
Adams County, IL: what NOAA's tornado record says

Against the rest of the country, that is the 75th percentile for frequency. Illinois has 102 counties in this dataset; Adams County ranks 40 of them by frequency.
Has Adams County ever had a violent tornado?

Paying for it, if Adams County's history says you should
A storm shelter or in-residence safe room typically runs $2,890-$13,280 nationally, around $7,645 for a common single-family installation. No state-administered rebate program specific to Illinois was confirmed for this site - FEMA's own Hazard Mitigation Assistance grants fund 75% of an approved safe room nationwide, but only some states currently run a homeowner-facing application on top of that.
The gap a shelter does not cover
64,109 people live in Adams County, and a tornado outbreak's power loss usually reaches far more of Illinois than the tracks themselves touch. A portable battery unit is the faster, no-fuel way to bridge that outage.
County-level, not address-level
Treat this as a county-wide figure, not a prediction for one address. Adams County covers about 855 square miles, so a single touch here counts the same as a single touch in a county a fraction of that size. And records from before the 1990s, NOAA notes, undercount weaker tornadoes in areas with less storm-spotting coverage at the time. Adams County has about 64,109 residents.
