How To Prevent Your Property From Flooding In Heavy Rainfall. If you live in a flood zone, you already know that heavy rains can cause significant damage to your property. And it’s not if your property will get damaged, but whether a flood risk is low, moderate or high. Floods happen when there’s too much water runoff, and your drainage system can’t handle it.
And if your sewer system doubles as a storm drainage system, then rainwater can back up via the sewer’s pipes, causing flooding to your home or business. And that’s not the only way a flood can happen since rainwater can quickly enter your home via doors, windows and cracks in your home’s foundations.
Your property is in a high-risk area for floods, here are a few things that can help prevent it from flooding in heavy rainfall:
Make sure you stock up on sandbags, which are merely burlap bags that are filled with sandy soil and used to divert water away from your property. Know that they can’t be used as a barricade and won’t prevent flooding entirely, but it can stop it from happening too fast. And if you build a wall of them around your property, you can create a messy moat, which is why it’s necessary to know if there’s a grade around your property so that you can figure out how water will flow if it does start to flood.
- Grading your lot
If your lot doesn’t have a grade, you might want to build one yourself. You’ll ideally want about 10 feet of ground around your home with a slope of about six inches so that rainwater runs away from your property.
- Rain gutters
Adding rain gutters to your property can help prevent flooding, and their efficiency only increases when you add in things like splash pads and downspouts. Just make sure that you clean them regularly so that debris, leaves or trash don’t clog them up.
- Get your property a sump pump
If you can invest in a sump pump, do it! These pumps drain water from the inside of your property to the outside via a pipe, and are ideal for homes on level ground or have basement entrances located underground.
- Have flood insurance
To be on the safe side, make sure your homeowner insurance policy includes flood insurance!
