Stepped Slopes

Stepped Slope

What is This Treatment?

This technique consists of a series of small benches, typically between one and two feet in width. Stepped slopes control erosion by breaking up the slope length - reducing the velocity of stormwater runoff. The steps promote vegetative cover by capturing and retaining loose soil material.

When to Use This Treatment?

Consider Using With:

Benefits:

  • Reduced stormwater runoff volume and velocity.

  • Improved soil, seed, and water holding capacity on steep slope surfaces.

  • Improved potential for establishing vegetative cover on steep cut slopes.

Limitations:

  • May increase the cost of earthwork activities.

  • Requires site accessibility by earthwork equipment.

  • May not be practical for sandy or rocky soils.

  • For cut slopes only.
