Every effort shall be taken during all phases of this project to ensure that sediment-taden water is <br /> not allowed to enter the stream. <br /> 10. Erosion control methods shall be used to prevent silt-laden water from entering the stream. <br /> These may include, but are not limited to, straw bales, filter fabric, temporary sediment ponds, <br /> check dams of pea gravel-filled burlap bags or other material, and/or immediate mulching of <br /> exposed areas. <br /> 11. Prior to starting work, temporary filter fabric, straw bale, or pea gravel-filled burlap bag check <br /> dam(s) shall be installed downstream. Accumulated sediments shall be removed during the project <br /> and prior to removing the erosion control methods after the completion of work. <br /> 12. Wastewater from project activities and water removed from within the work area shall be routed <br /> to an area landward of the ordinary high water line to allow removal of fine sediment and other <br /> contaminants prior to being discharged to the stream. <br /> 13. All waste material such as construction debris, silt, excess dirt or overburden resulting from this <br /> project shall be deposited above the limits of flood water in an approved upland disposal site. <br /> 14. If high flow conditions that may cause siltation are encountered during this project, work shall <br /> stop until the flow subsides. <br /> 15. Extreme care shall be taken to ensure that �o petroleum products, hydraulic fluid, fresh cement, <br /> sediments, sediment-laden water, chemicals, or any other toxic or deleterious materials are alloH�ed <br /> to enter or ieach into the stream. <br /> PROJECT LOCATIONS <br /> Location #1 Costco Outfall <br /> WORK START: April 04, 2006 WORK END: December 31, 2007 <br /> WRIA: Waterbody: Tnhutary to: <br /> 08.6029 Silver Lake North Creek <br /> 1/4 SEC: Section: Township: Range: Latilude: LangiWde: County: <br /> All 19 27 N 05 E N 47.9040 W 122.2073 Snohomish <br /> Localion p1 Dnving Oireclipns � <br /> Unnamed Uib to Silver Lake <br /> Page 2 of 4 <br />
