Paying for it, if Waller 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 Texas 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
The storm that misses Waller County outright can still take its power out - outbreak-scale outages across Texas are common well beyond the tracked path. A battery-backup unit handles that without a generator's setup or fuel.
Check your coverage, not just your risk
Because Texas allows wind/hail exclusions on standard homeowners policies, a Waller County homeowner should confirm tornado wind damage is actually covered, not assume it - a separate endorsement is common here.
County-level, not address-level
Treat this as a county-wide figure, not a prediction for one address. Waller County covers about 513 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. Waller County has about 65,109 residents.
