Key takeaways
- NOAA lists 305 flash flood reports in Dallas County since 1996, plus 22 additional flood reports.
- On August 21–22, 2022, upwards of 15 inches of rain fell in parts of Dallas, flooding homes, apartments, and dozens of roads.
- Standard homeowners and commercial policies generally exclude flood. Coverage comes from the NFIP or a private flood policy.
- Water from a burst pipe or rain through a storm-damaged roof is different from flood and is often covered by a homeowners policy.
- NFIP policies typically have a 30-day waiting period, so coverage has to be in place before the storm.
- Photograph water lines and damaged items before cleanup, and report a flood claim promptly.
Dallas is not on the coast, and most people do not think of it as flood country. The NOAA record says otherwise. When slow-moving storms stall over the Metroplex, several inches of rain can fall in an hour or two. Storm drains back up, creeks like White Rock, Turtle, Five Mile, and Duck Creek leave their banks, and underpasses fill with water. Flash flood damage can reach homes and businesses that have never flooded before.
The harder part often comes after the water recedes, when owners learn that their homeowners policy treats flood very differently from other water damage. This guide explains the difference, how flood insurance works, and what to do if your Dallas County property takes on water.
Flash flooding in Dallas County by the numbers
The NOAA National Centers for Environmental Information (NCEI) Storm Events Database lists 305 flash flood reports for Dallas County from 1996 through June 2026, plus 22 flood reports. Flash flood reports cluster in late spring and early summer, but they appear in every month.
| Month | Flash flood reports | Share |
|---|---|---|
| January | 18 | 5.9% |
| February | 12 | 3.9% |
| March | 25 | 8.2% |
| April | 23 | 7.5% |
| May | 60 | 19.7% |
| June | 57 | 18.7% |
| July | 17 | 5.6% |
| August | 33 | 10.8% |
| September | 17 | 5.6% |
| October | 19 | 6.2% |
| November | 10 | 3.3% |
| December | 14 | 4.6% |
| Total | 305 | 100% |

The recent trend is worth noting. 2025 had 44 flash flood reports, the most of any year in the record, and 2026 already had 21 by the end of June. As with any NOAA count, more reporting through social media and emergency managers accounts for part of that increase, but the pattern lines up with what Dallas residents have seen on their own streets.
Major Dallas County flash floods
August 21–22, 2022
The August 2022 flood is the benchmark for modern Dallas flooding. NOAA reports that upwards of 15 inches of rain fell in some areas, and that numerous roads, vehicles, homes, and buildings were flooded and heavily damaged. In Balch Springs, which NOAA describes as the hardest-hit area with over 15 inches measured, residents were rescued from homes along Hickory Tree Road in knee- to thigh-deep water. In Mesquite, more than 10 inches fell in a few hours and I-635 at Scyene Road was closed by high water. In east Dallas, 2 feet of water entered an apartment complex and knocked a front door off its hinges. Dallas police reported at least 42 roads with high water calls.
May 29, 2015
After a very wet May, 3 to 8 inches of rain fell across the county. NOAA reports that Duck Creek in Garland overflowed its banks and affected properties along the creek, with cars swept from driveways near Glenbrook and Carroll Drives. Loop 12 between Irving Boulevard and I-30 was closed for nearly four days, and the first floor of an apartment complex near South Belt Line Road flooded, forcing residents to evacuate.
June 11, 2009
Training thunderstorms parked over Dallas County that morning. NOAA reports that Turtle Creek overflowed its banks in Highland Park, where about six homes were flooded and a chest-deep water rescue took place where Fitzhugh and Wycliff cross the creek. Dallas Fire and Rescue had conducted 48 water rescues by 7:30 a.m., homes were evacuated near Sylvan Avenue and McBroom Street, and lightning strikes knocked out a pump at a Dallas pumping station serving parts of west Dallas, making the flooding worse.
Recent events
- January 30, 2025: Dallas Fire Rescue boats rescued six people from a flooded home on Fireside Drive, and numerous roads across Dallas, Garland, and Irving were flooded and closed.
- March 4, 2026: In Balch Springs, the emergency manager reported several houses with water inside, with water rescues in Cedar Hill and Duncanville.
- June 19, 2026: Cars were submerged to the windshield at the Harry Hines and Spur 482 underpass, and intersections along Northwest Highway near Bachman Lake were flooded and closed.

Flood vs. covered water damage: why the source matters
For insurance purposes, not all water is the same. Most homeowners policies cover some kinds of sudden water damage and exclude others. The cause of the water, not how much damage it did, usually decides which policy responds.
| Source of water | Homeowners policy (typical) | Flood policy (typical) |
|---|---|---|
| Rising water from a creek, river, or lake | Excluded | Covered, subject to terms |
| Surface runoff from heavy rain entering the home | Excluded | Usually covered when it meets the policy’s flood definition |
| Rain entering through a wind- or hail-damaged roof or window | Often covered | Generally not |
| Sudden burst pipe or appliance supply line | Often covered | Not covered |
| Sewer or drain backup | Often excluded without an endorsement | Only when caused directly by flood |
| Long-term leak or seepage | Usually excluded | Not covered |
A single storm can involve more than one category. Hail can break a skylight while street water enters the garage. In those cases, two policies may each cover part of the loss, and clear documentation of where each kind of water came from becomes important. Our page on water damage claims covers the non-flood side in more detail, and our guide to freeze damage and burst pipe claims in Dallas addresses plumbing failures.
How flood insurance works
NFIP and private flood policies
Most flood insurance in Texas is written through the National Flood Insurance Program, which FEMA manages and insurance agents sell. Private flood policies are also available. According to FloodSmart.gov, NFIP residential policies offer up to $250,000 in building coverage and up to $100,000 in contents coverage, purchased separately. Private policies may offer different limits and terms.
The 30-day waiting period
NFIP policies typically take effect 30 days after purchase, with limited exceptions. That means you cannot wait for a forecast of heavy rain over Dallas to buy coverage. If your property is near White Rock Creek, Turtle Creek, Five Mile or Ten Mile creeks, Rowlett Creek, or in a low spot that collects runoff, it is worth reviewing your flood coverage well before May.
What NFIP typically covers and limits
- Building coverage generally includes the structure and foundation, electrical and plumbing systems, HVAC equipment, water heaters, built-in appliances, and permanently installed flooring and cabinets.
- Contents coverage is separate and covers personal belongings, often at actual cash value under the standard dwelling form.
- Limits apply to items below the lowest elevated floor and in basements. Most Dallas homes are slab-on-grade, but older pier-and-beam homes in areas like Lakewood, the M Streets, and Oak Cliff have crawlspaces, where coverage can be more limited.
- Additional living expenses are generally not covered by NFIP policies, unlike many homeowners policies.
Rebuilding after a flood
If a building in a mapped floodplain is substantially damaged, the local floodplain administrator may require it to be elevated or otherwise brought up to current floodplain rules before it is rebuilt. NFIP policies include Increased Cost of Compliance coverage that may help with some of those costs when the community determines the building is substantially damaged. Inside the city, permits for flood repairs go through the City of Dallas Planning & Development Department; suburbs such as Mesquite, Garland, and Balch Springs have their own offices. Ask about permit and floodplain requirements before rebuilding.
These are general descriptions. Your Standard Flood Insurance Policy or private flood policy controls, and it is worth reading before you need it.
Filing a flood claim: practical steps
- Stay safe. Do not walk or drive through floodwater. Turn off power at the breaker only if you can do it safely, and call Oncor or Atmos Energy for electrical or gas hazards.
- Document the water line on walls, cabinets, and appliances with photos and video before cleanup. Measure the depth if you can.
- Photograph damaged items before you throw them away, and keep samples of flooring, carpet, and drywall when practical. Ask your adjuster before discarding large items.
- Report the claim promptly to your flood insurer and, if any part of the damage could be wind, hail, or plumbing related, to your homeowners insurer as well.
- Start drying out quickly to limit mold, and keep receipts for fans, dehumidifiers, and mitigation services.
- Watch the proof of loss deadline. NFIP claims generally require a signed proof of loss within a set period after the loss, and FEMA sometimes extends it after major events. Ask your flood adjuster for the current deadline in writing.
- Keep organized records using our claim documentation checklist.
Cleanup is necessary, but take photos of every room and keep a written list of what was removed and why. Once materials are gone, it becomes difficult to show the extent of the damage or to argue that more of the structure was affected.
When a flood claim is denied or underpaid
Flood claims are often disputed over the cause of the water, how far the damage extends, and whether items below the lowest floor are covered. A homeowners claim for storm-related water can be denied when the insurer decides the water was flood. If you disagree, ask for the reasoning in writing and review the policy language with someone who knows it. Our page on denied insurance claims explains common next steps, and questions about appeals or lawsuits should go to a Texas attorney.
How a public adjuster can help
Dallas Public Adjuster, a service of Rise Public Adjusting LLC, helps Dallas County property owners with flood damage claims and the water damage claims that often come with them. That can include documenting the loss, separating flood damage from covered wind, hail, or plumbing damage, preparing a detailed estimate, and presenting the claim. Fees are disclosed in a written contract before any work begins; Texas law caps public adjuster compensation at 10% of the insurance settlement. Coverage always depends on the policy and the facts, and no result is guaranteed. If you are unsure which policy should respond to your water damage, a Dallas Public Adjuster review can help you sort it out.
Frequently Asked Questions
Does homeowners insurance cover flash flood damage in Dallas?
Generally, no. Standard homeowners and commercial property policies usually exclude flood, which includes surface water, overflowing creeks, and rising water. Flood coverage typically comes from a separate National Flood Insurance Program (NFIP) policy or a private flood policy. Check your own policy for the exact wording of its flood exclusion.
Is water that came through my roof during a storm considered flood?
Usually not. Rain that enters through an opening created by wind or hail, such as a damaged roof or broken window, is often covered by a homeowners policy as part of the storm damage. Flood generally refers to water that rises from the ground or overflows from a body of water. The source of the water is what matters.
Do I need flood insurance if I am not in a high-risk flood zone?
Many flood losses happen outside mapped high-risk zones, especially in flash floods when storm drains are overwhelmed. Several Dallas County flash flood reports describe water entering homes and apartments in neighborhoods away from the Trinity River. Coverage outside high-risk zones is often less expensive. Talk with your agent about your property’s risk.
How long does it take for a flood policy to start?
NFIP policies typically have a 30-day waiting period before coverage takes effect, with limited exceptions. If heavy rain is already in the forecast, it is usually too late to buy coverage for that storm. Private flood policies may have different waiting periods.
Is sewer backup covered after heavy rain?
Many standard policies exclude water that backs up through sewers or drains unless you purchased a water backup endorsement, often with its own limit. Flood policies may cover backup only when it is caused directly by a flood. Check your declarations page for a water backup endorsement.
Can a public adjuster help with a flood claim?
A public adjuster can help document and present flood claims, and can review whether any part of the loss falls under your homeowners policy instead. NFIP claims follow federal rules and their own deadlines, so ask how fees and timing work before you sign any contract.
