Erosion is the process by which soil, rock, or other material is moved from one location to another, typically through the action of water or wind. Sediment control practices are designed to prevent or minimize loss of eroded soil at a site. Typical sediment control practices focus on the following.
- Physical filtration of sediment by trapping soil particles as water passes through a silt fence, drop inlet screen, fiber roll, etc.
- Settling processes, that allow sediment to fall out of flows that are slowed and temporarily impounded in ponds, traps, or in small pools created by berms, silt fencing, inlet protection dikes, check dams, and so on
This page provides links to several pages in this manual that address sediment control at construction stormwater sites, as well as links to other pages and information related to erosion prevention practices.

Permit applicability
Warning: The Construction Stormwater General permit states "The Permittee(s) must stabilize all exposed soil areas (including stockpiles)." For more specific information, see Part IV.B.2 of the permit.
