Slopes up to what percentage should be landscaped to prevent erosion?

Landscaping slopes is crucial for preventing erosion, especially as the percentage of the slope increases. Generally, slopes that are 25% or less are considered manageable for landscape interventions to prevent erosion effectively. At this gradient, vegetation can establish root systems that help anchor the soil, diminish water runoff velocity, and promote water infiltration. Proper landscaping, such as planting grass, shrubs, or trees, can stabilize the soil and prevent the effects of erosion caused by wind and water movement.

Slopes steeper than 25% require more specialized erosion control measures, such as terracing or using erosion control fabrics, because the risk of soil movement and loss significantly increases. Therefore, landscaping is most effective and recommended for slopes up to 25%, making this the correct choice for preventing erosion.
