Erosion is the movement of earthen materials from one area to another due to forces such as wind, water, and ice. This process occurs slowly under natural conditions. However, erosion is often accelerated by anthropogenic activities, such as [[Erosion and Sediment Control|construction]], agriculture, and deforestation (AAFC, 2025)<ref>Agriculture and Agri-Food Canada. 2025. Soil erosion. https://agriculture.canada.ca/en/environment/resource-management/indicators/soil-erosion.</ref>. This accelerated rate of erosion can compromise the effectiveness of LID systems and impact watershed health.

One way Conservation Authorities manage the risk of erosion is by recommending the use of [[Erosion and Sediment Control|Erosion and Sediment Controls (ESC)]] during construction projects. An ESC plan may be required for projects within a Regulated Area. For more information, contact [https://trca.ca/conservation/erosion-risk-management/ TRCA's Erosion Risk Management department].
