Storm water is outdoor water. It arrives carrying street runoff, yard chemicals, and whatever the creek picked up, so a flash flood cleanup starts as a contamination job and only becomes a drying job after the unsalvageable material is out of the building.

Or call (512) 566-1943The Lower Colorado River Authority calls the Hill Country stretch of the Colorado River Flash Flood Alley and describes it as one of the greatest flash flood risks in the country, pointing to steep terrain, shallow soil, and unusually high rainfall rates as the combination behind it. The authority runs a monitoring network of 275 automated weather and river gauges feeding near-real-time readings, and notes that once water is released at Mansfield Dam it reaches Tom Miller Dam in roughly an hour and a half. Lake Travis sits full at 681 feet above mean sea level with another 33 feet of flood pool above that, holding 776,062 acre-feet. Those figures explain the local pattern: rain that fell somewhere you cannot see can put water in a building here on a short clock.
Small urban creeks carry startling volumes during these events. The USGS gauge on Waller Creek at 23rd Street in Austin, with a peak record running from 1951 to 1980, logged its highest annual peak at 4,020 cubic feet per second and a gage height of 9.00 feet on October 11, 1973. That is a creek most people step over on a walk downtown. A building near a channel like that is not exposed to a slow rise; it is exposed to a short, violent stage change followed by a drop, which is why the interior evidence of how high water got is often gone within hours and has to be recorded immediately.
Austin Watershed Protection reports more than 1,100 miles of smaller ditches and drainage pipes carrying stormwater before it ever reaches a creek, and says storm drain capacity may be undersized in neighborhoods built before drainage regulations took effect in the early 1980s and in areas annexed later. That is the mechanism behind a large share of local water intrusion: the street cannot take the volume, water ponds, and it enters at a door sill, a garage slab, or a window well. The distinction matters because the entry route, the water's contamination level, and the coverage question all differ from creek overbank flooding, and the file needs to say which one happened.
The National Weather Service's Texas flood record includes the October 17 and 18, 1998 event, when 31 people died, damages ran to roughly 750 million dollars, and more than 30 inches of rain fell in 36 hours south of San Marcos, with many of the deaths occurring at low water crossings. Its account of the 2002 South Central Texas floods lists 12 fatalities and around 48,000 homes damaged. Those are not distant statistics for anyone doing cleanup work here. Nobody enters a building with moving water around it, nobody drives a flooded crossing to get to a job, and nobody works in standing water on an energized circuit.
Porous material that took outdoor floodwater is removed rather than dried. That includes carpet and pad, wet fiberglass insulation, particleboard and paper-faced material, and drywall to a line set by readings above the visible water mark. Contents get sorted into salvageable, cleanable, and discarded, with the discarded items photographed and listed before they leave. Silt and organic debris are cleaned off hard surfaces before any air moves, because drying a contaminated surface just distributes what is on it. Only after removal and cleaning does the drying equipment go in.
The single most useful record on a storm loss is the height of the water, photographed against a fixed reference like a door frame, and the date and time it was taken. Add photographs of the entry point, the exterior grade and drainage condition, dated moisture readings, and an itemized list of removed material with square footage. Flood water arriving from outside the building is treated differently by policies than a pipe failure inside it, and the difference is decided on the facts recorded that day. Keep receipts for anything bought during the emergency, including pumps and fuel.
Confirm the building is safe to enter and that power to affected areas is off, then pump and extract standing water. Remove unsalvageable porous material and debris under a written scope with photographs and measurements. Clean hard surfaces, then set containment and dehumidification sized to the wet area, with air introduced into wall cavities rather than aimed at painted surfaces. Readings are logged on each return visit until materials reach target. Because these events hit many addresses at once, equipment goes out on committed written scopes rather than on verbal promises, and the sequence is published so a homeowner knows what happens on day two and day five.

Why it matters: Creek and floodplain exposure is a local reality. A clear record of where water entered helps distinguish flood damage from a burst pipe and guides safe restoration scope.

Austin Water reports tap water hardness averaging 93 ppm as calcium carbonate, or 5.4 grains per gallon, with a reported range of 70 to 126 ppm. A USGS water-supply guide classifies 61 to 120 ppm as moderately hard and 121 to 180 ppm as hard, and says calcium and magnesium are largely responsible for deposits in hot-water heaters and pipes.
Why it matters: Scale builds inside tanks, valves and supply connections, so a water heater or fixture failure here is often the end of a slow mineral problem rather than a random event. That changes what gets inspected after the water is removed.

The National Weather Service Austin/San Antonio office recorded pockets of one to two inches of combined sleet and freezing rain in parts of the Austin area on January 24 and 25, 2026, mainly in Travis and Williamson counties, with parts of the region staying below freezing for more than 48 hours. NOAA's climate office puts central Texas, Austin included, at six to nine consecutive days of freezing temperatures during the February 11 to 20, 2021 freeze.
Why it matters: Multi-day freezes are what split supply lines in attics, garages and exterior walls, and the damage usually appears at the thaw rather than during the cold. Freeze losses arrive in clusters, which is why documentation and a written scope matter on each address.
