Element # 1: Mark Clearing Limits Prior to beginning construction activities, all clearing and construction limits shall be delineated. The clearing limits are typically marked with a construction fence (BMP C103). The TESC Plan shows the clearing limits for the project. Element #2: Establish Construction Access The site is currently accessible to construction vehicles from a driveway off 132"d Street SE. If sediment tracking becomes an issue during construction, it is recommended that a Wheel Wash (BMP C106) be utilized. No sediment tracking on the roadway is allowed. In the event that sediment is inadvertently tracked onto the road, the road shall be cleaned thoroughly by the end of that day. Sediment shall be removed from roads by shoveling, sweeping or by another approved means and transported to a controlled sediment disposal area. No street washing of sediments to the storm drain system will be allowed. Element #3: Control Flow Rates Given the size of the project and the layout, Silt Fencing (BMP C233) should be sufficient to control generated runoff during construction by utilizing containment areas with Silt Fencing along the perimeter. See the plan exhibits in Appendix B. If it is determined that additional measures are needed or instructed by the Inspector, contact the Certified Erosion Control Lead or Project Engineer immediately to discuss. Additional BMPs may be employed as needed as field conditions warrant. Element #4: Install Sediment Controls Storm Drain Inlet Protection (BMP C220) shall be installed on all catch basins located near the project site. See the TESC Plan in Appendix B. Element #5: Stabilize Soils Exposed and un-worked soils, such as soil stockpiles, shall be stabilized by application of effective erosion control measures that protect the soil from the erosive forces of raindrops, flowing water, and wind. Such measures include Plastic Covering (BMP C123) and Temporary and Permanent Seeding (BMP C120). The "Wet Season" is from October 1 to April 30. Within this period, no soils shall remain exposed and un-worked for more than 2 days. The "Dry Season" is from May 1 to September 30. Within this period, no soils shall remain exposed and un-worked for more than 7 days. This stabilization requirement applies to all soils on -site, whether at final grade or not. Soils shall be stabilized at the end of each shift before a holiday or weekend (if needed) based on the weather forecast.
