All proposed projects that will clear, grade or otherwise disturb a site must provide erosion and sediment controls to prevent, to the maximum extent possible, the transport of sediment from the project site to downstream drainage facilities, water resources, and adjacent properties. Both temporary and permanent erosion and sediment controls shall be designed, implemented and maintained as described in Section 1.2.5 and Appendix D of the King County Surface Water Design Manual.
(Ord. 395 § 3, 2003; Ord. 518 § 1, 2008)
All erosion and sediment control measures shall be maintained and inspected on a regular basis as prescribed in Appendix D of the KCSWDM. The applicant shall designate an erosion and sedimentation control (ESC) supervisor who shall be responsible for maintenance and inspection of the erosion and sedimentation control measures for compliance with all permit conditions relating to erosion and sediment control as described in Appendix D. The ESC supervisor will be responsible to submit reports to the City for each inspection of the site. Section D.5.4 of Appendix D of the King County Surface Water Design Manual sets forth the minimum schedule for erosion and sediment control reviews/inspections. For sites within or impacting sensitive areas, the City may require the ESC supervisor to be a licensed professional engineer with demonstrated expertise in erosion and sediment control. This professional shall be designated as a special inspector in conformance with Chapter 13.05 UPMC, Article VII.
(Ord. 395 § 3, 2003; Ord. 518 § 1, 2008)
Prior to obtaining final construction approval and the release of financial guarantees, the site shall be stabilized, structural erosion and sediment control measures (such as silt fences and sediment traps) shall be removed and the drainage facilities shall be cleaned as specified in Appendix D of the King County Surface Water Design Manual.
