Texas flood insurance and flood history
From FEMA's flood insurance and disaster data · Updated 2026-10-08
FEMA's National Flood Insurance Program (NFIP) data lists 394,204 flood insurance claims in Texas since 1978. The NFIP paid $17.4 billion on them (building, contents and Increased Cost of Compliance payments, in the dollars of the year paid).
The year with the most claims was 2017, with 93,589, mostly from Hurricane Harvey.
In the last ten years (2017–2026) there were 124,721 claims, and the average paid claim was $103,863.
51% of the claims with a recorded flood zone came from buildings outside FEMA's high-risk zones (rated zones B, C and X).
About 5.8% of homes in Texas had an NFIP flood policy in FEMA's latest count (504,754 of 8,773,166 residential buildings). In the high-risk flood zones (Special Flood Hazard Areas), it was 48% (171,141 of 360,062).

What to do with this
A county's history doesn't tell you your own building's risk. To see your property's flood zone, use FEMA's flood map lookup. To weigh coverage, start with do I need flood insurance? and what flood insurance costs.
Where these numbers come from
All figures on this page are calculated from FEMA's public OpenFEMA datasets:
- NFIP Redacted Claims (v3) (FEMA (OpenFEMA)): NFIP claims since 1978, downloaded 2026-10-08. Dollar amounts are what the NFIP paid, not adjusted for inflation. Claims filed under private flood insurance aren't included.
- NFIP Residential Penetration Rates (v1) (FEMA (OpenFEMA)): NFIP residential policy contracts in force (as of August 3, 2026) divided by FEMA's count of residential buildings from the National Structure Inventory. FEMA notes that inventory is incomplete in some counties, which can inflate the rate. Private flood policies aren't counted.
- Disaster Declarations Summaries (v2) (FEMA (OpenFEMA)): disaster declarations, downloaded 2026-10-08. We count a declaration as flood-related when FEMA lists flooding (or a dam or levee break) as its incident type or a designated incident type, or the declaration's title mentions flooding.
FEMA's redacted claims data doesn't identify properties, and FEMA notes that some records lack a county or flood zone. See how we use the data.
