Flood Preparedness for Guadalupe River Communities
By Ben Jernigan, "Dr. Moisture" — WTR Restoration
Know Your Risk
The Guadalupe and Comal Rivers are beautiful assets to our region, but they also pose a flood risk — especially during spring storms and reservoir releases. Homes and businesses near the rivers in New Braunfels, Seguin, and San Marcos should prepare for potential inundation.
Preparation Steps
- Understand your flood zone via FEMA Flood Insurance Rate Maps (FIRMs).
- Purchase flood insurance — standard policies do not cover flood damage, and there's a 30-day waiting period.
- Elevate critical systems — HVAC, water heaters, and electrical panels above potential flood levels.
- Create an emergency plan with evacuation routes and a documents/supplies kit.
During a Flood Event
- Heed evacuation orders. Six inches of moving water can sweep away a vehicle.
- Shut off utilities if it's safe to do so.
- Avoid contaminated water — floodwaters often carry sewage, chemicals, and debris.
After the Flood
Call WTR Restoration as soon as you can re-enter safely. We provide large-scale water extraction, structural drying, and sanitizing services. If sewage was involved, see our Category 3 sewage cleanup protocol. We document the damage for your insurance claim and remove contaminated materials per IICRC S500 standards.
