Water damage in Bexar County
Not affiliated with Bexar 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 Bexar County
Between 2020 and 2024, 55 flood-insurance claims in Bexar County recorded a building payment. 42 of them — 76% — came from losses in 2021. That works out to 0.1 claims per 1,000 homes over those years — 117th highest of 254 Texas counties. About 5.8 of every 1,000 homes here carry a flood-insurance policy — 124th highest of 254 Texas counties. Most of Bexar County's recent flood-claim record comes from one year, so a run of quiet years here is not evidence that the next one will be quiet.
What's the source? Tap one — the right help depends on it.

Historical NFIP flood-claim outcomes — Bexar County
Not a forecast for your loss. These are flood-insurance (NFIP) building claims only — a burst pipe or appliance leak is usually a homeowners-policy matter, and outcomes depend on your coverage, cause, and documentation.
City-level breakdowns, share-paid rates, and time-to-payment will publish only when claim-level geography and full methodology (numerators, denominators, status filters, code) are finalized and reproducible.
After the immediate emergency
Once the area is safe and the water is stopped, the full step-by-step lives on our statewide guide so it stays in one authoritative place:
