RM 1-2 instream Restoration <br />For RM 1-2 instream restoration, 60% design is complete. The restoration approach for RM 1-2 is to <br />restore the creek to its historic channel width, improve floodplain and side channel connectivity, limit <br />the duration of annual dewatering of the creek, and increase instream and side channel habitat <br />complexity. This restoration action will restore one mile of instream habitat by constructing 75 <br />engineered logjams and installing 196 toe habitat logs in the stream, and constructing five high-flow <br />side channels totaling 0.86 mi. Restoration actions will also restore 2.9 acres of floodplain at 16 <br />different locations with roughness logs and vegetation plantings. The total estimated implementation <br />cost is $5,178,000 for 2024. <br />RM 2-3 Instream Restoration <br />For RM 2-3 instream restoration, 60% design is nearly complete. The approach for RM 2-3 is the same <br />as RM 1-2, which is to restore the creek to its historic channel width, improve floodplain and side <br />channel connectivity, limit the duration of annual dewatering of the creek, and increase instream and <br />side channel habitat complexity. The 60% designs will be available in November 2022, Design specifics <br />and costs will be updated when available. Current implementation estimate is $7,000,000. RM 2-3 will <br />utilize helicopter placement for wood to decrease the impact of on the ground machinery and to deliver <br />the logs to rugged, hard -to -reach terrain. <br />Gold Creek Pond Restoration <br />For Gold Creek Pond Restoration, 30% design is complete. There are three alternatives being considered <br />through the National Environmental Policy Act (NEPA) process. <br />1. Forested Wetland Complex— would fill most of the existing pond and convert the area back to a <br />forested wetland complex, similar to its historic condition. This alternative would significantly <br />reduce, if not eliminate completely, the dewatering effect the pond has on the creek. It would <br />also remove berms and infrastructure and fill the outlet channel. New tributary channels would <br />be established to connect Gold Creek to the forest wetland complex. <br />2. Multi -Pond Alternative — would elevate the pond to bring the ground water up, requiring an <br />earthen dam at the southern end to contain the water. Smaller ponds would be constructed <br />with varying elevations. This alternative would remove the berms and fill the outlet channel. <br />3. Gold Creek Integration Alternative —would integrate Gold Creek into the restored pond and <br />create in-line habitat. It would be similar to the multi -pond alternative, but would allow <br />migrating fish to have access to the ponds for holding while the creek is in its dewatered stage. <br />This alternative would remove the berm and fill the outlet channel. <br />All three alternatives are estimated to cost about the same to construct. Approximately 900,000 cubic <br />yards of fill will be required to fully fill the pond. Estimated implementation cost for the Gold Creek <br />Pond Restoration is $11,000,000. <br />Heli's Pond restoration <br />For Hell's Pond Restoration, 30% design is complete. Hydraulic models show that completely filling Heli's <br />Pond will increase surface water flow in Gold Creek, nearly eliminating the dewatering effects on the <br />creek. A 75% pond fill would decrease the siphon effect and decrease costs of implementation. The <br />landowner, Forterra, will have the final approval on the design. A 100% fill would require an estimated <br />17,600 cubic yards and the implementation cost is estimated at $1,760,000. <br />4 <br />
