Site Entry Erosion Control Best Management Practice

Erosion control best management practices are required during all ground disturbing activity until permanent site ground covers are in place. A best management practice (BMP) is a physical, chemical, structural or managerial practice that prevents, reduces or treats contamination of water or which prevents or reduces soil erosion.

Site entry BMPs control accesses to and from a site of ground disturbance can go a long way to controlling mitigation of sediments of the worksite. Site entry BMPs should be the first erosion measures installed at any site.

Site Entry BMPs are:

  • Gravel Construction Entrances
    • Contain sediments (rock, dirt, mud) on site.
    • Provide access without the use of gravel ramp (wooden curb ramp)
    • Prevent vehicles from tracking dirt onto improved roadways
  • Wooden Curb Ramp
    • Provide ramp access to stabilized construction entrance without blocking flow or adding sediments to curb runoff
