Round Rock sits along Brushy Creek, which produced the 1981 Memorial Day flood that killed 13 people in Williamson County. Texas Hill Country storms can drop 5 to 10 inches in hours, and FEMA maps designate several Round Rock neighborhoods as Special Flood Hazard Areas. Every hour of delay deepens the loss.
The area's expansive clay soils shift with seasonal moisture, stressing slab plumbing and producing slow leaks that saturate walls for weeks. The February 2021 freeze showed how quickly burst pipes can release hundreds of gallons into framing and insulation.
Texas homeowners insurance covers sudden losses like burst pipes but excludes rising floodwater; a separate NFIP or private flood policy is required. Ask your contractor for daily drying logs — Texas insurers must accept or deny a claim within 15 business days of receiving full documentation.
