Water damage in Calhoun County
Not affiliated with Calhoun County, any city government, FEMA, TDI, or any government agency.
Leave and call for emergency help FIRST if any of these:
- Ceiling sagging or bulging, or any structural movement → get out from under it; leave if spreading
- Gas odor → leave now, call your gas utility from outside
- Sparking, energized water, or a wet breaker panel → do not touch; call the electric utility or 911
- Large-scale sewage flooding → keep everyone (especially kids, pets, and medically vulnerable people) away from the water; call emergency services for any immediate medical or life-safety risk — otherwise isolate the area and use the sewer branch below
Safety information only: Conditions vary. This guidance is not a substitute for instructions from 911, utilities, public-health officials, licensed professionals, your insurer, or your policy. If anyone may be in danger, leave the area and call 911. Do not take any step you cannot perform safely.
What this means in Calhoun County
Between 2020 and 2024, 40 flood-insurance claims in Calhoun County recorded a building payment. 32 of them — 80% — came from losses in 2021. That works out to 3.7 claims per 1,000 homes over those years — 6th highest of 254 Texas counties. About 138 of every 1,000 homes here carry a flood-insurance policy — 8th highest of 254 Texas counties. Flood cover is far more common in Calhoun County than in most of Texas, which usually reflects mapped flood zones and lender requirements rather than an individual property's exposure.
