Prepare for the Storm: How to Use Sandbags for Flood Protection

As tropical weather systems begin to form, many Orange County residents are turning to a tried-and-true defense against flooding: sandbags. Whether you have used them before or this is your first time, here is what you need to know to make the most of this simple but effective tool.

How Sandbags Work

Sandbags act as a temporary barrier against rising water. When placed correctly, they can divert or block water from entering your home, garage or low-lying areas on your property. The sand inside absorbs water and forms a tight seal that slows or prevents flow.

Before You Start Sandbagging

Before stacking that first bag, take a look around your property. Identify the lowest entry points — typically doors, garages or basement windows — and decide where water is most likely to flow. Remember, sandbags are for minor flooding. If you live in an evacuation zone or flood-prone area, have an evacuation plan ready.

Filling and Stacking Sandbags

Filling sandbags is a two-person job: one to hold the bag and one to shovel. Only fill each bag about halfway; this makes them easier to handle and better for stacking. Don’t tie them closed — leave the top open and flat so it molds better when stacked.

Setting Up Sandbags and a Tarp

For extra protection, use a plastic tarp under your sandbag barrier. Lay the tarp with several feet of excess material on both sides of where the bags will go. Stack the bags in a staggered pattern, like brickwork, and tuck the tarp edges in as you go. This combination can deflect water even more effectively.

Building a Sandbag Levee

If you need to build a longer barrier — along a driveway, for example — build your sandbag levee in a pyramid shape, with a broad base tapering to a single row at the top. Always build with the flow of water in mind and leave a path for drainage if necessary.

Sandbagging Tips

• Wear gloves and sturdy shoes when working with sandbags.
• Don’t reuse old sandbags — wet bags can harbor bacteria or mold.
• Avoid placing sandbags directly against walls; they work better when slightly offset to slow water.

Know When to Evacuate

No sandbag barrier can stop a serious flood. If local officials recommend evacuation, do not wait — go. Have a go-bag ready, know your route and check updates on weather and traffic.

Where to Get Sandbags

Before a major storm, Orange County will open self-serve sandbag sites. Residents can pick up to 10 unfilled bags and fill them on-site with sand provided. Bring proof of Orange County residency and your own shovel or spade. Individuals with disabilities can call OCFL 311 or 407-836-3111 for assistance.
