Erosion and sediment controls (ESC) are technologies, practices and procedures that are applied to prevent the release of sediment from construction sites.
Erosion and sediment controls (ESC) are technologies, practices and procedures that are applied to prevent the release of sediment from construction sites.
Rapid urban expansion and associated construction activities are a significant source of stress to the natural environment. As construction processes involve the removal of vegetation and de-stabilization of soils, they can accelerate natural processes of erosion and sedimentation, mobilizing more sediment and associated contaminants that can ultimately end up in downstream receiving water systems. Erosion and Sediment Control (ESC) measures are essential to help reduce these sediment loads from active construction sites and protect downstream aquatic habitats from becoming impaired.

Implementing effective ESC practices throughout all stages of construction is essential to sustainable urban growth and ensuring regulatory compliance.
Implementing effective ESC practices throughout all stages of construction is essential to sustainable urban growth and ensuring regulatory compliance. The Toronto and Region Conservation Authority, through STEP, published the [http://sustainabletechnologies.ca/app/uploads/2020/01/ESC-Guide-for-Urban-Construction_FINAL.pdf ''Erosion and Sediment Control Guide for Urban Construction''] in 2019. This wiki page summarizes key content from the guide and provides additional resources; however, readers should consult the full guide for comprehensive information. https://sustainabletechnologies.ca/home/erosion-and-sediment-control/esc-guide/
