Texas Flood
Texas Flood History
Moving west, the state has a stretch of hills, with lower water table. Water runs off quickly in the hill country, which is primarily formed of limestone and rock and hills.

Why Texas Leads the Nation in Flood Risk
No state floods like Texas. From Gulf hurricanes and tropical storms to the flash-flood corridor known as “Flash Flood Alley” running through Central Texas, the state sees more flood damage than anywhere in the country. Hurricane Harvey alone dumped more than 60 inches of rain on the Houston area in 2017 and produced over 500,000 flood-damaged vehicles and tens of thousands of flooded homes — the majority of them outside designated high-risk flood zones.
Who Should Carry Flood Insurance in Texas?
- Coastal and Gulf-region homeowners from Houston and Galveston to Corpus Christi and Beaumont, where storm surge and tropical rainfall are annual threats.
- Houston-area homes near bayous and reservoirs. The flat coastal plain drains slowly; neighborhoods far from the coast flooded during Harvey.
- Central Texas “Flash Flood Alley” residents around Austin, San Antonio, and the Hill Country, where thin soil over limestone sends rainfall straight into creeks.
- Anyone in Zone X. Roughly 1 in 5 NFIP claims come from low- and moderate-risk zones — and in Texas that share runs even higher after major storms.

NFIP vs. Private Flood Insurance in Texas
As an independent brokerage we quote both. NFIP offers up to $250,000 building and $100,000 contents coverage and is accepted by every lender. Private flood insurance has grown fast in Texas — often with higher limits, additional living expenses, and competitive pricing, especially for well-elevated homes. After Harvey, many Texans found private markets filled gaps NFIP couldn’t. We compare both side by side.
How Much Does Flood Insurance Cost in Texas?
- Preferred Risk (Zone X): often $400–$700 per year.
- Moderate-risk properties: typically $700–$1,500 per year.
- High-risk coastal/surge zones (A/AE/V): commonly $1,500–$4,000+, driven by elevation and proximity to the coast.
Coastal Texas premiums run higher than inland because of surge exposure — but even a modest policy is a fraction of an uninsured flood loss, which averaged over $100,000 per home after Harvey.
Frequently Asked Questions
Is flood insurance required in Texas?
Lenders require it for federally backed mortgages on homes in FEMA high-risk zones (A, AE, V). Elsewhere it’s optional, but given Texas’s flood history most coastal and Houston-area homeowners carry it regardless of zone.
Does homeowner’s insurance cover flooding in Texas?
No. Texas homeowner’s and windstorm policies exclude rising-water flood damage. Only a dedicated flood policy covers surge, tropical rainfall, and river flooding.
Is there a waiting period?
NFIP policies generally take effect 30 days after purchase, so you cannot wait for a storm in the Gulf to buy coverage. Private policies may bind faster. Buy before hurricane season, which runs June through November.
Do you cover all of Texas?
Yes — statewide, from Houston, Galveston, and Corpus Christi to Austin, San Antonio, Dallas–Fort Worth, and the Hill Country. Quote online or call 855-225-3566.
