Construction: erosion and sediment control measures (view source)

, 2 years ago→Erosion and sediment control measures
Establish required perimeter controls, including erosion and sediment control (ESC) measures, prior to construction and adjust accordingly during construction. ESC measures come in two basic types: structural ESC, which slows and holds runoff from the disturbed area, dissipating erosive forces, promoting ponding, and allowing suspended particles to settle out; and non-structural ESC, which primarily minimizes the exposure time of stripped soils. STEP’s [https://sustainabletechnologies.ca/app/uploads/2020/01/ESC-Guide-for-Urban-Construction_FINAL.pdf Erosion and Sediment Control Guide] contains detailed guidance on the design, installation, inspection, maintenance, and decommissioning of ESC measures. This section gives simple, practical advice on structural and non-structural ESC for contractors, inspectors, and those who are new to construction and ESC practices.

For non-structual ESC measures, be sure to:
For non-structual ESC measures, be sure to:
*Stage clearing and grubbing to minimize exposure of stripped soils.
