When a slope begins as a vertical cut, what is a common stabilization technique?

When a slope starts as a vertical cut, a common stabilization technique involves removing the upper sections of the slope. This approach addresses the potential for instability that can arise from steep vertical cuts, which may lead to soil erosion or landslides. By removing the upper sections, the slope can be reconfigured to a more stable angle, promoting better drainage and reducing the risk of failure. This adjustment creates a gentler slope that can better support the weight of the soil and any additional structures or vegetation placed above it.

Removing the upper sections not only reduces the steepness of the slope but also allows for better integration of stabilization methods, such as planting vegetation, which can further reinforce the soil and enhance stability. In contrast, while adding retaining walls and other techniques may be applicable in some scenarios, they may not directly address the inherent instability caused by a vertical cut as effectively as re-grading the slope.
