Flash Flood in Lawrenceville? Here’s What to Do Before, During, and After: A Safety Guide.

Flood and Storm Restoration

Flash floods can strike Lawrenceville with little to no warning—especially during storm season in Gwinnett County. A sudden burst of heavy rain, poor drainage, or overflowing creeks like Sweetwater Creek can quickly turn streets into rivers and basements into water hazards.

At PuroClean of Lawrenceville, we understand the chaos and fear that flooding can cause. That’s why we’ve created this in-depth guide to help local residents prepare before the storm, stay safe during it, and recover quickly after the waters recede.

Before the Flood: Be Proactive, Not Reactive

When it comes to flash floods, preparation is everything. Taking time to get ready now can protect your property, your belongings, and—most importantly—your family.

How to Prepare for Flash Floods in Lawrenceville:

  1. Understand Your Flood Risk
    Flood-prone areas like those near Sweetwater Creek, Alcovy River, or in lower elevations are especially vulnerable. Check FEMA flood maps and monitor local weather forecasts regularly.
  2. Protect Your Property
    • Clean gutters and downspouts to allow rainwater to flow freely.
    • Make sure sump pumps and backflow valves are working properly.
    • Elevate HVAC units and electrical appliances off the ground floor if possible.
  3. Move Valuables to Higher Ground
    Relocate important documents, electronics, heirlooms, and anything irreplaceable to a higher floor or waterproof container.
  4. Create a Flood Emergency Kit
    Include:
    • Bottled water & non-perishable food
    • Flashlights, batteries, and power banks
    • First-aid supplies and medications
    • Waterproof bags for documents
    • A whistle, blankets, and hygiene items
  5. Develop a Family Evacuation Plan
    Know your evacuation routes. Practice them with your family. Keep your car’s gas tank at least half full during storm season.
  6. Stay Informed
    Sign up for Gwinnett County emergency alerts, weather apps, or NOAA radio to receive real-time flood warnings.

During the Flood: Safety Comes First

When a flash flood warning is issued or you notice rising water, act immediately. Lives are lost every year to fast-moving water that could’ve been avoided.

Flash Flood Safety Tips:

  • Never drive through floodwaters.
    As little as 6 inches can stall a car, and 12 inches can carry it away. “Turn Around, Don’t Drown.”
  • Avoid walking through moving water.
    It may contain contaminants like sewage, oil, or sharp debris.
  • Unplug and turn off electrical appliances, but only if you can do so safely without stepping into water.
  • Evacuate when advised.
    Don’t wait for things to get worse. Grab your emergency kit and follow your evacuation plan.
  • Keep children and pets safe and away from floodwater at all times.

If you’re sheltering in place, move to higher ground and keep a phone charged for emergency calls. Avoid using elevators during floods.


After the Flood: Act Fast to Minimize Damage

Once the rain stops and the water recedes, the real work begins. Unfortunately, flood damage doesn’t end when the water disappears—it’s just the beginning.

Without rapid response, your home may face:

  • Mold growth within 24–48 hours
  • Warped flooring, rotting wood, and crumbling drywall
  • Structural damage
  • Bacteria and biohazard exposure
  • Severe financial loss

What You Should Do Immediately After a Flood:

  1. Ensure Personal Safety
    Only return home if authorities have deemed it safe. Wear waterproof boots, gloves, and masks before entering a damaged area.
  2. Document Everything for Insurance
    Take photos and videos of all damage before you begin cleanup or throw anything away. Keep a detailed inventory of lost items.
  3. Don’t Attempt DIY Cleanup
    Flood cleanup involves hazardous materials, hidden moisture, and contaminated water. Leave it to professionals with the right training and equipment.
