How to Measure Yard Grade for Drainage: Tools and Techniques

To establish drainage slope, you need to measure grade accurately. A transit level (rental or $400+ to buy) is the professional standard. Digital laser grading rods exist but require two people. For most residential projects, a 4-foot level, string line, and line level are sufficient and cheaper. Contractors still rely on these simple tools. If you're using a tractor, a laser receiver on the bucket can help, but the basic principles of slope (¼ inch per foot minimum away from structures) remain the same.
