The hybrid qualitative ERA approach is recommended in the above situations, except where local regulatory agencies require a different approach. The hybrid qualitative ERA approach estimates [[Erosion#Erosion_potential|erosion risk]] by dividing a site into areas based on [[soil groups|soil]], [slope], and ground cover, then rating each area as low, moderate, or high [[Erosion#Erosion_potential|erosion risk]] to help choose the right erosion control practices for each stage of construction. Completing an ERA demonstrates due diligence, identifies high-risk areas early, informs effective BMP selection and placement, guides the use of enhanced controls, and provides context for decision-making. To learn more about ERAs, read section 6.2 in the [http://sustainabletechnologies.ca/app/uploads/2020/01/ESC-Guide-for-Urban-Construction_FINAL.pdf Erosion and Sediment Control Guide for Urban Construction] (2019).
