Do you have adequate protection on your slopes to minimize the potential for erosion during construction activity?

Implementing effective best management practices (BMPs) to temporary stabilize disturbed soil on slopes should be considered during construction activities to reduce the potential for erosion which can result in polluted discharges.

The purpose of slope protection during construction is to reduce the potential for erosion by decreasing runoff velocities, trapping sediment, shortening slope length, and increasing infiltration into the soil.

Consider implementing or installing a series of BMPs on your disturbed slopes such as:

  • Erosion control blankets (ECB)
  • Turf reinforcement mats (TRM)
  • Velocity dissipators
  • Tackifiers
  • Seeding and planting
  • Hydromulch
  • Slope drains
  • Slope roughening/terracing
  • Plastic/visquine

Inspection and maintenance of BMPs on slopes includes inspecting areas for rill and gully erosion, sedimentation, and vegetation establishment.

Regulations may require slope protection for steep slopes, slopes with soils that are highly erodible, or for long slopes. Be sure you understand what types of slope protection is required and what is needed on your site!
