Washington Department of Fish&Wildlife HYDRAULIC PROJECT APPROVAL PO Box 43234 Depsdreenl Olympia,WA 98504-3234 FISH WEDLEE (360)902-2200 Issued Date: January 22, 2015 Permit Number: 2015-4-41+01 Project End Date: October 15, 2015 FPA/Public Notice Number: N/A Application ID: 1650 STREAM/RIPARIAN ENHANCEMENT 5. Bank sloping shall be accomplished in a manner that avoids release of overburden material into the water. Overburden material resulting from the project shall be deposited so it will not reenter the water. 6. Installed streambed substrate shall be composed of clean,well-rounded material that is similar in size to the bed of the adjacent stream. 7.All habitat logs and/or rootwads shall be fir, cedar, or other approved coniferous species. 8. All existing large woody material (LWM)shall be reinstalled or repositioned to remain in the low flow channel. LWM embedded in a bank or bed shall be left undisturbed. 9. Erosion control methods shall be used to prevent silt-laden water from entering the stream. These may include, but are not limited to, straw bales, biodegradable filter fabric, and/or immediate mulching of exposed areas. 10.All bare earth areas shall be protected from erosion and appropriately revegetated prior to final inspection or completion of the project. 11. REVEGETATION AND PLANTING REQUIREMENT: Disturbance of the streambed, banks, and their associated vegetation shall be limited to that necessary to perform the project. Affected streambed and bank areas shall be restored to pre-project or improved habitat configuration prior to the fall or spring dormant periods following project completion. The banks shall be revegetated with native or other approved woody species, as shown in the approved planting plan (Provision 2).All new vegetation shall be maintained as necessary for three years to ensure 80 percent or greater survival. BYPASS 12. A temporary bypass or containment structure (i.e. sand bags, aqua dam)shall be used to divert flow around the work area and be in place prior to initiation of work in the wetted perimeter. 13. The bypass or containment structure shall allow all expected flows and debris to pass for the duration of the project. 14. Prior to releasing the water flow to the project area, all in-water work shall be completed and all material used in the temporary bypass or other diversion method shall be removed from the site and the site returned to pre-project or improved conditions. GENERAL 15. If high flow conditions that may cause siltation are encountered during this project,work shall stop until the flow subsides. 16. Wastewater from project activities and water removed from within the work area shall be routed to an area landward of the OHWL to allow removal of fine sediment and other contaminants prior to being discharged to the stream or to wetlands associated with the stream. 17. The use of equipment below the ordinary high water line shall be limited to hand held tools only. 18. Equipment used for this project shall be free of external petroleum-based products while working around the stream. Equipment shall be checked daily for leaks and any necessary repairs shall be completed prior to commenci Page 2 of 6..
