Solving yard drainage problems requires a systematic approach that addresses both surface runoff and subsurface groundwater. According to the guide, you can implement several targeted solutions:

1. Improve Surface Grading: Establish a positive slope of at least 5% (about 1/2 inch of fall per foot) extending 6 to 10 feet away from your foundation. Use clean fill soil and compact it in 4- to 6-inch layers to prevent future settling.
2. Install a French Drain: Dig a trench 18–24 inches deep with a slope of 1 inch per 8 feet. Line it with geotextile fabric, add gravel, and lay a perforated pipe with the holes facing down to redirect groundwater away from low spots.
3. Manage Roof Runoff: Attach extensions to your downspouts to discharge water at least 5–10 feet away from the house. Use splash blocks or buried PVC pipes to prevent water from saturating the soil near the foundation.
4. Install a Perimeter Drain System: For high-stakes issues, a professional system at the footing level can intercept groundwater before it accumulates against the foundation, relieving hydrostatic pressure.
5. Address Sunken Concrete: Use polyurethane foam lifting to restore the proper grade on sunken patios or walkways that trap water against the home.
6. Create Natural Infiltration: Install dry wells or rain gardens with deep-rooted native plants to capture and hold concentrated runoff from roofs and driveways.
