Project Description 3a. Describe the existing conditions on the site and the general land use in the vicinity of the project at the time of this application: This project is located on Forest Service Road 137 (aka Daniel Ridge Trail) and once provided access to a fish rearing station on upper Davidson River. It appears that the site has been a concern for more than a decade, evidenced by attempts to drain the road fill material. Despite these efforts, the road fill material had slumped into the river during the 2004 hurricane rainstorms and is at risk of continuing to be a source of sediment to the river. Soil movement seems to be initiated by the many seeps and springs in the landmass that tend to saturate the soil and lubricate the soil bedrock interface. Also, the toe of the slump is located in the Davidson River at the outside of a meander bend where streamflow energy and erosion potential are high during flood events (Figure 1). High flow of the river is likely to exacerbate the already high erosion potential of the slope. N a C i n l �!' � r. r � � X19 �+k. , 2• �,��w,• } �r Figure 1.

Explain the purpose of the proposed project: The purpose of this project is to stabilize the soil on the hillslope and keep it from entering Davidson River. Page 4 of 12 3e Describe the overall project in detail, including the type of equipment to be used The following is proposed 1) Excavate the remaining road fill material (slumping landmass) to a stable slope and haul soil off site, depositing it along the existing road bed. 2) During excavation, remove all pipes and note location of water flow, 3) Relocate several large boulders in the river to the toe of the slope redirect flow away from the toe of the slope and create a bankfull bench (to dissipate energy on a floodplain feature). Import quarry - boulders to supplement existing large boulders as needed (See Appendix A for details) Top the constructed bench with transplants from the site to the bankfull elevation. 4) Construct natural looking channels on the hillside to drain the slope, using boulder and imported river cobble as needed where water flow is likely down to Davidson River 5) Sow native seed and cover bare soil with Coir matting, and plant the area with trees and shrubs (including live stakes). 6) Construct dips in the road/trail to drain water away from the site. 7) Relocate the trail across the area, minimizing trail width and cutting into the bank Construct an outsloped trail with rolling dips and hardened surfaces at stream crossings and potential wet areas to reduce rutting This work would be accomplished using a medium sized trackhoe excavator and a dump truck to haul off excavated material The purpose of this project is to stabilize the soil on the hillslope and keep it from entering Davidson River 4.

Davidson River is classified by the state of North Carolina as Class B - Trout, Water - Supply watershed, and High - Quality Waters. Erosion and sedimentation is the largest risk to water quality in this watershed of the French Broad River Basin. tAn XV �C. bLi IJ4 AJk 90.

It appears that the site has been a concern for more than a decade, evidenced by attempts to drain the road fill material. Despite these efforts, the road fill material had slumped into the river during the 2004 Davidson River Stream Bank Stabilization @ Daniel Ridge Trail (FSR 137) Project Page 1 hurricane rainstorms and is at risk of continuing to be a source of sediment to the river. Soil movement seems to be initiated by the many seeps and springs in the landmass that tend to saturate the soil and lubricate the soil bedrock interface. Also, the toe of the slump is located in the Davidson River at the outside of a meander bend where streamflow energy and erosion potential are high during flood events (Figure 2). High flow of the river is likely to exacerbate the already high erosion potential of the slope. Figure 2. Davidson River project site looking upstream. Note pipes extending from fill material. Proposed Action The following is proposed: 1) Excavate the remaining road fill material (slumping landmass) to a stable slope and haul soil off site, depositing it along the existing road bed. 2) During excavation, remove all pipes and note location of water flow, 3) Relocate several large boulders in the river to the toe of the slope redirect flow away from the toe of the slope and create a bankfull bench (to dissipate energy on a floodplain feature). Import quarry- boulders to supplement existing large boulders as needed (See Appendix A for details). Top the constructed bench with transplants from the site to the bankfull elevation. 4) Construct natural looking channels on the hillside to drain the slope, using boulder and imported river cobble as needed where water flow is likely down to Davidson River. 5) Sow native seed and cover bare soil with Coir matting, and plant the area with trees and shrubs (including live stakes), (See Appendix A for details). 6) Construct dips in the road /trail to drain water away from the site. 7) Relocate the trail across the area, minimizing trail width and cutting into the bank. Construct an outsloped trail with rolling dips and hardened surfaces at stream crossings and potential wet areas to reduce rutting. Davidson River Stream Bank Stabilization @ Daniel Ridge Trail (FSR 137) Project Page 2 This work would be accomplished using a medium sized trackhoe excavator and a dump truck to haul off excavated material. The purpose of this project is to stabilize the soil on the hillslope and keep it from entering Davidson River. Environmental Impacts & Mitigation Construction would occur during dry weather conditions when seeps on the hillslope are mostly inactive. Temporarily increases in turbidity would occur during excavation in the stream channel and on the sideslope, but the amount would be minimized by diverting river current away from the work and by the use of silt fence at the toe of the slope. Directly following excavation, erosion control measures (transplants, coir matting, etc.) would further minimize erosion and sedimentation to Davidson River. Potential adverse impacts would be avoided by minimizing excessive excavation and adhering to the State turbidity standard. Work is expected to be completed over a three -four day period.

Davidson River Stream Bank Stabilization @ Daniel Ridge Trail (FSR 137) Project Page 9 PISGAH ZONE CATEGORICAL EXCLUSION IDT REVIEW CHECKLIST (For Projects Not Requiring a Decision Memo) For a proposed action that fits an excluded category that does not require a project or case file and decision memo (FSH 1909.15.32.1), this form summarizes the results of an IDT review of the activity and serves to verify completion of the analysis required to identify extraordinary circumstances, as defined in FSH 1909.15.312, that would preclude the use of the categorical exclusion Name of Project: Davidson River Restoration at Daniel Ridge Ranger District: Pisgah County: Transylvania Date: 5/29/2014 LRMP Management Area: 18 Categorical Exclusion: 36 CFR 220.6(d)(4) - Repair and maintenance of roads, trails, and landline boundaries. Description of Project: This project is located on FSR 137 (aka Daniel Ridge Trail) and once provided access to a fish rearing station on upper Davidson River. It appears that the site has been a concern for more than a decade, evidenced by attempts to drain the road fill material. Despite these efforts, the road fill material has slumped into the river and is at risk of continuing to be a source of sediment to the river. Soil movement seems to be initiated by the many seeps and springs in the landmass that tend to saturate the soil and lubricate the soil bedrock interface. The toe of the slump is located at the outside of a channel bend where streamflow energy is high during runoff events in the Davidson River. High flow of the river is likely to exacerbate the already high erosion potential. To stabilize the slumping landmass the following is proposed: 1) Excavate the slumping landmass to a stable slope and haul soil off site, 2) during excavation, remove all pipes and note location of water flow, 3) relocate several boulders at the toe of the slope in the river, 4) construct natural looking channels using boulder and imported river cobble where water flow is likely down to Davidson River, 5) sow native seed and cover bare soil with Coir matting, and plant the area with trees and shrubs (including live stakes), 6) construct dips in the road to drain water away from the site, and 7) relocate the trail across the slump minimizing trail width and cutting into bank. Use an outsloped trail with rolling dips and hardened surfaces at stream crossings and potential wet areas to reduce rutting. This work would be accomplished using a medium sized trackhoe excavator and a dump truck to haul off excavated material. This work is estimated to cost $10,000. Scoping: internal scoping along with Trout Unlimited Review of Extraordinary Circumstances The following resource conditions have been reviewed by specialists to determine whether extraordinary circumstances related to a proposed action warrant further analysis and documentation In an EA or an EIS (FSH 1909 15 31 2) The mere presence of one or more of these resource conditions does not preclude use of a categorical exclusion (CE) It is the existence of a cause - effect relationship between a proposed action and,the potential effect on these resource conditions and if such a relationship exists, the degree of the potential effect of a proposed action on these resource conditions that determine whether extraordinary circumstances exist (36 CFR 220 6(b)) Specialists responsible for review of each resource condition will mark the condition as not applicable, resource not present, resource present -no effect, or resource present - possible effects and sign in the following table or provide an email to be filed In the project folder.
