Paying for it, if Porter County's history says you should
Indiana's Indiana Department of Homeland Security's Residential Safe Room Program is the number that matters for a Porter County homeowner: 75% of an approved shelter, capped at $5,000, cutting the typical $2,890-$13,280 national range to about $722.5-$8,280 net.
The gap a shelter does not cover
175,860 people live in Porter County, and a tornado outbreak's power loss usually reaches far more of Indiana 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. Porter County covers about 418 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. Porter County has about 175,860 residents.
