Hayward September 08, 2021 <br /> All temporary erosion and sediment control BMPs shall be removed within 30 days after the <br /> final site stabilization is achieved or after the temporary BMPs are no longer needed.Trapped <br /> sediment shall be removed or stabilized on site. Disturbed soil resulting from removal of BMPs <br /> or vegetation shall be permanently stabilized. <br /> Element#12—Manage the Project <br /> Erosion and sediment control BMPs for this project have been designed based on the following <br /> principles: <br /> • Design the project to fit the existing topography, soils, and drainage patterns. <br /> • Emphasize erosion control rather than sediment control. <br /> • Minimize the extent and duration of the area exposed. <br /> • Keep runoff velocities low. <br /> • Retain sediment on site. <br /> • Thoroughly monitor site and maintain all ESC measures. <br /> • Schedule major earthwork during the dry season. <br /> Element#13—Protection of Lid BMP's <br /> During the construction of the Ryan Hayward project all proposed BMP's on-site shall fully <br /> comply with the DOE's regulations for Element#13. Restore the BMP to their fully functioning <br /> condition if they accumulate sediment during construction. Restoring the BMP must include <br /> removal of sediment, and replacing the removed soils with soils meeting the design <br /> specification. Protect completed lawn and landscaped areas from compaction due to <br /> construction equipment. Keep all heavy equipment off existing soils under LID facilities that <br /> have been excavated to final grade to retain the infiltration rate of the soils. <br />
