Poor Drainage?

 Creating Proper Drainage in a Floodplain

Managing water flow in a floodplain is crucial to prevent flooding and protect your property. Here are some effective methods for proper drainage:

1. Slope the Ground Away From the House:

   • Ensure that the ground around your house slopes away from the foundation.
   • Add soil to create a gentle slope, directing water away from the house.
   • Maintain a minimum of 4 inches between the slope and the bottom of the siding1.

2. Replace Hardscapes with Drainage Materials:

   • Concrete or asphalt surfaces can sometimes divert water toward the house.
   • Replace these hardscapes with crushed gravel or pea gravel to encourage even drainage1.

3. Install a Rain Barrel:

   • Collect rainwater from downspouts using a rain barrel.
   • Reconfigure downspouts to direct water into the barrel for later use in gardens1.

4. Add a Channel Drain:

   • If your driveway or walkway sends water in the wrong direction, install a channel drain.
   • Cut a narrow trench into the concrete or asphalt and place a long channel drain in it.
   • Redirect water away from the house or garage1.

5. Install a French Drain:

   • A French drain helps manage surface water across your lawn.
   • Dig a trench and lay perforated pipes surrounded by gravel.
   • Water flows into the pipes and is directed away from the floodplain1.

6. Green Infrastructure Practices:

   • Consider rain gardens, bioswales, and permeable pavements.
   • These enhance infiltration and help manage water runoff2.

7. Maintain Gutters and Downspouts:

   • Regularly clean and maintain gutters, downspouts, and splash pads.
   • Ensure rainwater flows away from your home’s foundation3.

Remember that a combination of these methods can significantly improve drainage in a floodplain, keeping your property dry and secure.
