How to Stay Safe Before During and After a Flood in Central Texas

Flooding is the most common and deadliest natural disaster in the United States. Central Texas faces this threat regularly because it lies in "Flash Flood Alley," a region where heavy rain, dry limestone soil, and fast-moving creeks can quickly turn a calm day into a dangerous emergency. Whether you live near Onion Creek, a low-water crossing in Caldwell County, or a rural road in Southeast Travis County, knowing how to act when floodwaters rise can save your life.

Prepare Before a Flood Happens

The best time to get ready for a flood is before the rain starts. Taking a few simple steps now can make a big difference later.

Know your flood risk

• Visit FEMA’s Flood Map Service Center to check if your home is in a flood zone. Keep in mind many homes outside official flood zones have flooded in recent years, so don’t assume you are safe just because you’re not on the map.

Build a go-bag: Store this bag where you can grab it in under two minutes.

• Prepare a waterproof bag with essentials for at least 72 hours. Include:

  • One gallon of water per person per day

  • Prescription medications

  • Non-perishable food

  • Copies of important documents (ID, insurance, deeds)

  • Flashlight and extra batteries

  • Phone charger

  • Cash

Create a family plan

• Decide where your family will meet if separated. Identify two evacuation routes from your neighborhood. Pick an out-of-area contact everyone can call or text to check in.

Sign up for alerts

• Travis, Caldwell, and Hays residents can register for emergency notifications through Warn Central Texas. These warnings can give you crucial minutes to act.

Protect your home

• Consider flood insurance even if you’re outside a flood zone. Elevate utilities and appliances if possible. Clear debris from gutters and drains to help water flow away from your property.

What to Do During a Flood

When floodwaters rise, your safety depends on quick, smart decisions.

Avoid walking or driving through floodwaters

• Just six inches of moving water can knock you down. One foot of water can sweep a vehicle away. If you encounter a flooded road, turn around and find another route.

Move to higher ground

• If you are outside or in a low-lying area, get to higher ground immediately. Avoid low-water crossings and creek beds, which can fill rapidly.

Follow evacuation orders

• If local officials tell you to evacuate, do so without delay. Waiting can put you and your family in danger.

Stay informed

• Keep a battery-powered radio or your phone handy to receive updates. Do not rely solely on social media, as power outages can disrupt service.

Keep your go-bag close

• Have your emergency supplies ready to take with you if you need to leave quickly.

What to Do After a Flood

Flood dangers don’t end when the water starts to recede. Follow these steps to stay safe and recover effectively.

Wait for official word

• Do not return home until authorities say it is safe. Floodwaters can hide hazards like downed power lines, sharp debris, or unstable ground.

Avoid floodwater contact

• Floodwater can carry sewage, chemicals, and other contaminants. Avoid wading through it if possible. If you must, wear protective clothing and wash thoroughly afterward.

Inspect your home carefully

• Check for structural damage before entering. Look for cracks in the foundation, walls, or floors. If you smell gas or hear a hissing sound, leave immediately and call emergency services.

Document damage

• Take photos and videos of all damage for insurance claims. Keep receipts for any repairs or cleanup expenses.

Clean and disinfect

• Remove wet items and dry out your home quickly to prevent mold. Use disinfectants on surfaces that came into contact with floodwater.

Seek help if needed

• Contact local disaster relief organizations for assistance with shelter, food, or financial aid.
