Erosion prevention guidelines can be the simplest and most effective measures you can take to retain sediments on your site. The following guidelines protect and expose soil surfaces from rain-generated splash erosion. They can help slow flows across a site of ground disturbance. All sites should incorporate at least one type of erosion prevention measure when exposed to a ground-disturbing activity.
Surface roughening - erosion prevention measure
Reduce runoff velocity and allow for infiltration
Support the establishment of vegetative cover
Temporary grasses and permanent vegetative cover as erosion control
- Minimize erosion and sedimentation by stabilizing exposed soils with vegetation and mulching
Mulch and erosion prevention
Mulch is a name given to a group of organic and inorganic materials that are spread on the soil surface to prevent movement of soil by wind and rain. Mulch:
- Minimizes erosion by providing a protective cover over disturbed, bare or reseeded soils.
- Minimal thickness protects soils form splash erosion while thicker layers are effective for additional sediment control.
Use erosion control blankets
Erosion control blankets are mats comprised of organic fibers or inorganic materials held by synthetic or biodegradable netting.
- Prevent erosion from exposed soils in channels on slopes, or as a wet weather measure.
- Typically used when a vegetative cover cannot be achieved due to soils, the time of year or where slopes are too steep for mulch.
Surface roughening and erosion prevention
- Protect soils from contact with stormwater.
- Typically used when a vegetative cover cannot be achieved due to soils, time of year or where slopes are too steep for mulch.
Dust control to minimize erosion
Minimize wind erosion of bare soils.
