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.
