How to Build a Swale & Berm: Fix Yard Flooding for 1/10th the Cost!

Swale & Berm Guide: https://www.yarddrainagefixes.com/sol... Are you tired of standing water, soggy grass, or runoff from your neighbors flooding your yard every time it rains? In this video, we break down how to build a drainage swale and berm—one of the most effective, beautiful, and budget-friendly yard drainage solutions available. While most homeowners immediately think they need an expensive French drain, a swale and berm system is often the correct choice for surface water sheeting across a lawn. Best of all, it costs a fraction of the price (roughly $0.50 to $1.00 per square foot, compared to $10+ per linear foot for a French drain!). 👇 WHAT YOU'LL LEARN IN THIS VIDEO: Introduction to Swales & Berms Swale vs. French Drain: Which do you actually need? How Swales & Berms Work Together Quick Sizing & Slope Requirements Step-by-Step DIY Build Guide Common Mistakes That Make Swales Fail Maintenance Tips for Long-Term Success 🏡 SWALE VS. BERM: THE BASICS A SWALE is a broad, shallow, gently sloped channel (usually covered in grass) that intercepts surface runoff and guides it slowly to a safe outlet. A BERM is a low mound of soil built on the downhill side of the swale (often using the dirt you just dug out). It acts as a barrier to keep water in the channel. 🛠️ STEP-BY-STEP DIY INSTALLATION PROCESS: 1. Find the Path & Outlet first (e.g., a rain garden, dry well, ditch, or daylight edge). Never direct water toward your foundation or a neighbor's property! 2. Call 811 to locate underground utilities before you dig. 3. Mark your route following the natural curves of your yard. 4. Excavate shallow and wide (typically 8 to 18 inches deep and several feet wide) so it is easy to mow. 5. Build the berm on the downhill side with the excavated soil. 6. Establish a 1% to 2% grade (about 1 to 2 inches of drop for every 10 feet of length) to keep water moving without causing erosion. 7. Stabilize the surface immediately using sod, seed, or decorative stones (dry creek bed) to protect bare soil. 8. Test the flow with a garden hose or watch it during the next heavy rain. ⚠️ 6 MISTAKES TO AVOID: Having no clear, safe outlet. Grading it too flat (which creates a long, standing puddle). Grading it too steep (which causes severe soil erosion). Digging it too narrow and deep (making it look like a ditch and hard to mow). Leaving bare soil exposed to wash away in the first rain. Using a berm as a dam that backs water up against a neighbor or foundation.
