Yard Grading to Drain Away from House: Swale vs. French Drain

A house sitting lower than the surrounding yard with low spots draining toward the foundation needs positive drainage, not just French drains.

Recommended Approach

1. Swale (berm + ditch) around the house perimeter to intercept and redirect surface water. Most effective for overland flow.
2. Supplement with catch basins at strategic low points, piped to a discharge (daylight, dry well, storm sewer).
3. Trench drains across hardscape areas (driveway, patio) to capture sheet flow.
4. Level the “hump” (red box in photo) that traps water.

French drains alone are insufficient for surface water—they’re slow, clog-prone, and don’t intercept overland flow. An open swale system moves water fast and visibly.
