Shelter and safe-room economics
Michigan does not currently have a confirmed state rebate layered on top of FEMA's 75% Hazard Mitigation cost-share, so a Houghton County homeowner should expect the full national range: $2,890-$13,280, $7,645 typical.
Power after the storm, not just shelter during it
A direct hit is not required for Houghton County to lose power - outbreak-wide outages across Michigan regularly reach homes and businesses well outside the actual tracks. A battery bank covers that gap without a generator's fuel and venting needs.
What Houghton County's figure does not tell you
Houghton County's figure is county-wide, not address-specific. Houghton County covers about 1,009 square miles, so a single touch here counts the same as a single touch in a county a fraction of that size. NOAA also documents that older records undercount weaker tornadoes from before Doppler radar became standard. Houghton County has about 38,041 residents.
