Learn trail grade design from scratch with a clear step-by-step workflow, recommended tools, safety guidelines, and expert tips.
Use a clinometer or level app to record grade at 25 ft intervals along flagged centerline.
Flag sections exceeding target grade or lacking grade reversals for redesign.
Plan short dips and rises to shed water off the tread every 20–50 ft on steeper terrain.
Create a build sheet listing target grades, reversal locations, and bench-cut requirements.
USFS Trail Construction and Maintenance Notebook recommends reversals on all grades above 10%.
Trail grade should not exceed half the hillside slope to reduce erosion risk.
First storm reveals whether grade reversals actually shed water.
Never undercut unstable slopes without professional geotechnical review.
