Impacts Approved The following impacts are hereby approved as long as all of the other specific and general conditions of this Certification (or Isolated Wetland Permit) are met. No other impacts are approved including incidental impacts: Amount Approved (Unit s Plan Location or Reference Stream 1,200 feet Davidson River 2. Erosion & Sediment Control Practices Erosion and sediment control practices must be in full compliance with all specifications governing the proper design, installation and operation and maintenance of such Best Management Practices in order to protect surface waters standards: a. The erosion and sediment control measures for the project must be designed, installed, operated, and maintained in accordance with the most recent version of the North Carolina Sediment and Erosion Control Planning and Design Manual. b. The design, installation, operation, and maintenance of the sediment and erosion control measures must be such that they equal, or exceed, the requirements specified in the most recent version of the North Carolina Sediment and Erosion Control Manual. The devices shall be maintained on all construction sites, borrow sites, and waste pile (spoil) projects, including contractor-owned or leased borrow pits associated with the project. c. For borrow pit sites, the erosion and sediment control measures must be designed, installed, operated, and maintained in accordance with the most recent version of the North Carolina Surface Mining Manual. d. The reclamation measures and implementation must comply with the reclamation in accordance with the requirements of the Sedimentation Pollution Control Act. 3. No Waste, Spoil, Solids, or Fill of Any Kind No waste, spoil, solids, or fill of any kind shall occur in wetlands, waters, or riparian areas beyond the footprint of the impacts depicted in the Pre-Construction Notification. All construction activities, including the design, installation, operation, and maintenance of sediment and erosion control Best Management Practices, shall be performed so that no violations of state water quality standards, statutes, or rules occur. DavidsonRiver Page 3 of 6 March 7, 2006 4. No Sediment & Erosion Control Measures w/n Wetlands or Waters Sediment and erosion control measures shall not be placed in wetlands or waters to the maximum extent practicable. If placement of sediment and erosion control devices in wetlands and waters is unavoidable, they shall be removed and the natural grade restored within six months of the date that the Division of Land Resources has released the project. 5. Certificate of Completion Upon completion of all work approved within the 401 Water Quality Certification or applicable Buffer Rules, and any subsequent modifications, the applicant is required to return the attached certificate of completion to the 401/Wetlands Unit, North Carolina Division of Water Quality, 1650 Mail Service Center, Raleigh, NC, 27699-1650. 6. Construction in this creek and disturbance within a 25-foot trout buffer should be avoided during the October 15 to April 15 trout spawning period to avoid adverse effects of sediment on eggs and larvae. 7. Sediment and erosion control measures must be implemented prior to construction and maintained on the sites to minimize sediment in downstream areas. Seeding for a temporary cover of wheat, millet, or similar annual grain or permanent herbaceous cover should occur on all bare soil within five (5) days of ground disturbing activities to provide long-term erosion control. The projects should be accomplished in stages instead of leaving large tracts exposed to further storm events. Erosion control matting should be used in conjunction with appropriate seeding on disturbed soils in steep slope and riparian areas. Matting should be secured in place with staples, stakes, or, wherever possible, live stakes of native trees. Straw mulch and tall fescue should not be used in riparian areas. In addition, because of an anticipated difficulty in establishing ground cover during the winter, reseeding should be conducted, as necessary, in the spring-time with a native annual and perennial seed mix with a temporary nursery crop of wheat, millet or other grain. 8. Only clean, large, angular rock, large woody material, or other natural stream design materials and techniques should be used for bank stabilization. Rock should not be placed in the stream channel in a manner that constricts stream flow or that will impede aquatic life movements during low flow conditions. Filter cloth should be placed behind large rock that is used for bank stabilization. Properly designed rock vanes should be constructed wherever appropriate on bank stabilization and channel realignment stream reaches to improve channel stability and to improve aquatic habitat. Root wads should be installed low enough in the bank so that a significant portion (at least one-third) the root wad is inundated during normal flows. Should large, angular rock, large woody material, or other natural stream design materials and techniques not be sufficient for long term stability of the stream and adjacent roadway, and concrete be incorporated into the design, measures which would prevent surface waters from coming into contact with live concrete. 9. The channel should be restored to a more stable condition. However, under no circumstances should river rock, sand or other materials be dredged from the DavidsonRiver Page 4 of 6 March 7, 2006 stream channel under authorization of this permit except, if necessary, in the immediate vicinity of the eroding banks for the explicit purpose of anchoring stabilizing or flow/grade control structures or for reestablishing the natural and more stable stream channel dimensions. Stream bed materials are unstable in flowing- water situations and are unsuitable for bank stabilization. In stream dredging has catastrophic effects on aquatic life and disturbance of the natural form of the stream channel can cause downstream erosion problems. The natural dimension, pattern, and profile of the stream upstream and downstream of the permitted area should not be modified by widening the stream channel or changing its depth. No backfilling of stream bed materials is allowed under this authorization. 10. Stabilization measures should only be applied on or near existing erosion sites, leaving other stable stream bank areas in a natural condition. Grading and backfilling should be minimized and tree and shrub growth should be retained where possible to ensure long term availability of stream bank cover for aquatic life and wildlife. Backfill materials should be obtained from upland sites except in cases where excess stream bed materials are available. Berms should not be permitted because they block the floodplain, constrict and accelerate flood flows, and often fail and sometimes impede drainage during large flood events. 11. Repairs to eroded banks should be conducted in a dry work area. Sandbags or other clean diversion structures should be used to minimize excavation in flowing water. Channel realignments should be constructed by excavating the new channel from downstream to upstream before connecting it to the old channel. 12. Heavy equipment should be operated from the bank whenever possible. All 'mechanized equipment operated near surface waters should be inspected and maintained regularly to prevent contamination of stream waters from fuels, lubricants, hydraulic fluids or other toxic materials. Equipment used in stream channel must be clean, new or low hour equipment. Exposure of equipment to surface waters must be minimized to the maximum extent possible. 13. Disturbed stream banks and a 30-foot vegetated zone (as required under the HQW regulations), or the widest width that is practical under the site conditions, must be restored along the construction sites to natural riparian conditions with native trees and shrubs (e.g., silky dogwood, rhododendron, dog hobble, red maple, silky willow, tag alder, black willow, sycamore) to provide long-term bank stability and stream shading. Note, silky dogwood, silky willow and black willow can be planted as live stakes collected during the dormant growing season. Cuttings should be randomly planted on four (4) foot centers from the waters edge to the top of the bank. Trees should be planted on ten (10) to twelve (12) foot centers. Stream banks in these areas should also be seeded with a native annual and perennial seed mix with a temporary nursery crop of wheat, millet or other grain. Replanting of vegetation within disturbed areas located within 30 feet of the streambank associated with any land disturbing activity, repair, replacement and/or maintenance must be done in a manner consistant with the Guidelines for Riparian Buffer Restoration immediately following construction. (Please see attached.) 14. If pasture along the stream is to be used for grazing, a fence must be constructed outside of the riparian zone and the stream to prevent livestock from entering these areas. DavidsonRiver Page 5 of 6 March 7, 2006 15. Diffuse Flow All constructed stormwater conveyance outlets shall be directed and maintained as diffuse flow at non-erosive velocities through the protected riparian zones such that it will not re-concentrate before discharging into a stream. If this is not possible, it may be necessary to provide stormwater facilities that are considered to remove nitrogen. This may require additional approval from this Office. 16. Turbidity Standard The turbidity standard of 10 NTUs (Nephelometric Turbidity Units) shall not be exceeded as described in 15 A NCAC 2B. .0200. Appropriate sediment and erosion control practices must be used to meet this standard. 17. No Sediment and Erosion Control Measures in Wetlands Sediment and erosion control measures shall not be placed in wetlands or waters to the maximum extent practicable. If placement of sediment and erosion control devices in wetlands and waters is unavoidable, they shall be removed and the natural grade restored within six months of the date that the Division of Land Resources or locally delegated program has released the project. 18. Notification of Construction The applicant and/or authorized agent shall contact the DWQ Asheville Regional Office by phone at 828-296-4657 within 10 days of the commencement of construction.

This woody debris is causing the following problems: • The down tree is blocking part of the main channel of the Davidson River, which impedes recreational river use (e.g. canoeing and tubing) and poses a concern for public safety. • The down tree is partially re-directing streamflow into an over-flow channel at higher than baseflows, causing 40 feet of stream bank erosion at the inlet and outlet, and posing the threat of turning more flow into the side-channel during future stormflow events. The intent of the project is to re-establish the flow through the main channel of the Davidson River without eliminating the function of the side-channel, stabilize stream banks, and restore public safety through the following tasks: • Relocate the log from within the main channel in order to improve flow and boater safety. • Stabilize eroding stream banks in the side-charnel through the placement of large woody debris. The total anticipated disturbed area, due to equipment movement and excavation, is less than 1 acre and 140 linear feet of stream channel, which includes the main channel and the side-channel. The proposed work is expected to take up to two weeks (one week mobilization/demobilization and one week construction). The contractor will be directed to do the following related to sediment and erosion control: • Construction will take place between April 16 and October 14, outside of the period for brown and rainbow trout spawning. • Work activities would not be scheduled on rain days. • Minimize the degree and extent of disturbed areas.

Project Information ?attach a vicinity map clearly showing the location of the property with respect to local landmarks such as towns, rivers, and roads. Also provide a detailed site plan showing property boundaries and development plans in relation to surrounding properties. Both the vicinity map and site plan must include a scale and north arrow. The specific footprints of all buildings, impervious surfaces, or other facilities must be included. If possible, the maps and plans should include the appropriate USGS Topographic Quad Map and NRCS Soil Survey with the property boundaries outlined. Plan drawings, or other maps may be included at the applicant's discretion, so long as the property is clearly defined. For administrative and distribution purposes, the USACE requires information to be submitted on sheets no larger than 11 by 17-inch format; however, DWQ may accept paperwork of any size. DWQ prefers full-size construction drawings rather than a sequential sheet version of the full-size plans. If full-size plans are reduced to a small scale such that the final version is illegible, the applicant will be informed that the project has been placed on hold until decipherable maps are provided. 1. Name of project: Sycamore Flats Woody Debris Redistribution in Davidson River (VWP24) 2. T.I.P. Project Number or State Project Number (NCDOT Only): N/A 3. Property Identification Number (Tax PIN): N/A 4. Location County: Transylvania Nearest Town: Brevard, NC Subdivision name (include phase/lot number): N/A Directions to site (include road numbers, landmarks, etc.): From Asheville take Interstate 26E toward Asheville Airport and take the exit for State Route 280 toward Brevard. Take SR280 south to the intersection with US276; go west on US276 approximately %z mile and turn left into the Sycamore Flats Recreation Area. Park at the first set of parking spaces and walk west toward the overflow channel, which is visible from parking lot (the debris). 5. Site coordinates, if available (UTM or Lat/Long): 35° 16'34"N, 82° 42'52"W (NAD27) (Note - If project is linear, such as a road or utility line, attach a sheet that separately lists the coordinates for each crossing of a distinct water body.) 6. Property size (acres): Pisgah Ranger District (235,576 acres) 7. Nearest body of water (stream/river/sound/ocean/lake): Davidson River 8. River Basin: French Broad (Note - this must be one of North Carolina's seventeen designated major river basins. The River Basin map is available at http://h2o.enr.state.nc.us/admi.n/maps/.) Describe the existing conditions on the site and general land use in the vicinity of the project at the time of this application: As a result of the high flows during the hurricanes in 2004, this reach of Davidson River was blocked by large woody debris. Due to the location and arrangement of the woody debris in the main channel, more runoff than normal flows into an over-flow channel causing stream bank erosion. Also recreational enthusiasts can not float down this reach of Davidson River without portaging around the debris. It is a safety concern as someone may not be able to get out of the river in time and may become caught in the large woody debris. 9. Describe the overall project in detail, including the type of equipment to be used: In the project area there are several whole and partial trees spanning the Davidson River. They span from the bank of the overflow channel to a large point bar on the opposite side of the river. There is some bank erosion at the overflow channel (especially at the outlet) and at the streambank immediately adjacent to the southern end of the overflow channel. These areas of erosion would be stabilized as part of this project. The largest tree spanning from the bank over to the point bar is approximately 105' long with a 30" DBH. This tree needs to be cut before it can be moved. A large excavator with a thumb would be used to move the large woody debris to the streambanks. The bole of the tree, with root wads, would be anchored to the bank via a large boulder and a cable lasso at the inlet (Site 1) and via boulders at the outlet of the overflow channel (Site 2).. (See proposed action schematic.) 10. Explain the purpose of the proposed work: The intent is to re-establish the flow through the main channel of the Davidson River, stabilize stream banks in the over flow channel, and improve public safety by redistributing the large woody debris. IV. Prior Project History If jurisdictional determinations and/or permits have been requested and/or obtained for this project (including all prior phases of the same subdivision) in the past, please explain.

Proposed Impacts to Waters of the United States/Waters of the State It is the applicant's (or agent's) responsibility to determine, delineate and map all impacts to wetlands, open water, and stream channels associated with the project. The applicant must also provide justification for these impacts in Section VII below. All proposed impacts, permanent and temporary, must be listed herein, and must be clearly identifiable on an accompanying site plan. All wetlands and waters, and all streams (intermittent and perennial) must be shown on a delineation map, whether or not impacts are proposed to these systems. Wetland and stream evaluation and delineation forms should be included as appropriate. Photographs may be included at the applicant's discretion. If this proposed impact is strictly for wetland or stream mitigation, list and describe the impact in Section VIII below. If additional space is needed for listing or description, please attach a separate sheet. 1. Provide a written description of the proposed impacts: There will be short term sediment introduction into Davidson River at this location and also downstream of this location due to the excavator working in the river to move the large woody debris out of the main channel. There will also be short term soil displacement and sedimentation from digging in the streambanks of the over flow channel to place and anchor woody debris into the streambanks. Potentially, oil and other chemicals from the excavator could leak into the river during the implementation. 2.

Impact Justification (Avoidance and Minimization) Specifically describe measures taken to avoid the proposed impacts. It may be useful to provide information related to site constraints such as topography, building ordinances, accessibility, and financial viability of the project. The applicant may attach drawings of alternative, lower-impact site layouts, and explain why these design options were not feasible. Also discuss how impacts were minimized once the desired site plan was developed. If applicable, discuss construction techniques to be followed during construction to reduce impacts. Construction will take place between April 16 and October 14 outside of the period for brown and rainbow trout spawning. Work activities will not be scheduled on rainy days. Points of entry into Davidson River will be designated by a hydrologist. Over-hanging banks will be avoided. Equipment will be cleaned before entering the river, so as to eliminate a potential source of sediment and oils and grease. The degree and extent of disturbed areas will be minimized. Sediment fencing will be installed around all disturbed areas to trap potential sediment. All disturbed areas will be stabilized at the end of each workday, with temporary seeding and biodegradable and certified weed-free erosion control matting as work is completed. Upon completion of the project, stream banks will be planted with riparian vegetation such as dog hobble rhododendron, and dogwood for long-term stabilization. VIII. Mitigation DWQ - In accordance with 15A NCAC 2H .0500, mitigation may be required by the NC Division of Water Quality for projects involving greater than or equal to one acre of impacts to freshwater wetlands or greater than or equal to 150 linear feet of total impacts to perennial streams. USACE - In accordance with the Final Notice of Issuance and Modification.of Nationwide Permits, published in the Federal Register on March 9, 2000, mitigation will be required when necessary to ensure that adverse effects to the aquatic environment are minimal. Factors including size and type of proposed impact and function and relative value of the impacted aquatic resource will be considered in determining acceptability of appropriate and practicable mitigation as proposed. Examples of mitigation that may be appropriate and practicable include, but are not limited to: reducing the size of the project; establishing and maintaining wetland and/or upland vegetated buffers to protect open waters such as streams; and replacing losses of aquatic resource functions and values by creating, restoring, enhancing, or preserving similar functions and values, preferable in the same watershed. If mitigation is required for this project, a copy of the mitigation plan must be attached in order for USACE or DWQ to consider the application complete for processing.

Vicinity map of Sycamore Flats Woody Debris Redistribution (VWP24) project. Background Due to the storm events that occurred during the 2004 hurricane season, a woody debris jam developed and has blocked the main channel of Davidson River at the Sycamore Flats Recreational Area on the Pisgah National Forest (Figure 2). This woody debris is causing the following problems: • The debris jam is blocking part of the main channel of the Davidson River, which impedes recreational river use (e.g. canoeing and tubing) and poses a concern for public safety (Photos 1-4). • The debris jam is partially re-directing streamflow into an side-channel, causing 40 feet of stream bank erosion at the inlet (site 1) and outlet (site 2) (photos 5-8), 1 and posing a threat of turning more flow into the side-channel during future stormflow events.

Channel width of Davidson River is 60 feet and channel width of the side-channel is 30 feet. The areas between State Route (SR) 27, Forest Service Road (FSR) 257, and Davidson River are forested. There is an open area by the picnic table at site 2 (outlet of side-channel). Within the red oval is a supply of large woody debris to be used at Site 2. Planned Work FSR 257 will be closed to the public during the project. Staging will occur from the northern segment of the loop road. A tracked excavator with a thumb will be used at both sites 1 and 2. The intent of the project is to re-establish the flow through the main channel of the Davidson River without eliminating the function of the side-channel, stabilize stream banks, and restore public safety through the following tasks: • Relocate the debris jam from within the main channel to the inlet of the side- channel (site 1) in order to improve flow and boater safety. • Stabilize eroding stream banks in the side-channel through the placement of large woody debris (site 2). 2 Site 1 The objective at site 1 is to open up the main channel for the majority of the river flow and for recreational users, but still allow for storm flows to access the side-channel as needed and protect the stream banks from severe erosion. To access site 1, the excavator will use a user-created trail, which will be widened to accommodate the excavator. Upon completion of the project, the trail will be rehabilitated to pre- project condition. At the inlet of the side-channel, a tracked excavator will pull the woody debris from Davidson River (Photos 1 and 2) rotating the largest tree about the root wad on the right downstream bank of the side-channel (Figure 3). The largest tree will be cut to approximately the width of the side-channel at the inlet of the side-channel. The tops of the tree and other woody debris from the jam will be placed along the banks at the upper end of the inlet to protect the streambank and provide fish habitat. Root wads of the trees will be positioned on the right downstream bank of the side-channel, facing downstream. Root wads will serve the following functions: To provide protection for the stream banks. To collect debris during high flow events, acting as a debris jam in the side- channel. To provide fish cover in the side-channel and along the streambanks of the main channel of the Davidson River. A 5' to 6' boulder will be placed at the inlet of the side-channel, near the left bank. A cable will be attached to the tree and the boulder to anchor the large log in place. 3 Sycamore Flats Bank Stabilization Typical 2 I North Notto scale Existing User Trail e ?,, r„aui3n, ........... .......... ,Site 7 C sic 2 ? , / yam JF 1IN for, `Cs ??

Site 2 The excavator will collect woody debris from the side-channel (red oval in Figure 3) to be used at the outlet (site 2). Forty-feet of stream bank within the oval may be disturbed. A hydrologist or fish biologist will select woody debris to be used. The excavator should be able to remain on the widened user-created trail to collect the debris. The excavator will remain on the user-created trail and FSR 257 and use a new access trail to reach site 2. The new access trail will be rehabilitated. No trees will be removed. If necessary, the path will be scarified to break up compacted soils. Site 2 is characterized by an undercutting streambank that has overhanging roots and vegetation. Woody debris from the side-channel would be located to the base of this bank to provide protection during high storm events but still provide fish habitat. The exact placement of these logs will be determined by the hydrologist and fisheries biologist at the time of implementation. tl ...................................................... : relocation of large t woody debris 1 4 Photos Site 1: Debris jams at the inlet of the side-channel.

Temporary BMP's To reduce erosion and sedimentation of Davidson River, the contractor will be instructed to implement the following temporary BMP's during construction: A. Minimize the area of and degree of soil disturbance that reduces infiltration capacity and permeability and destroys protective forest floor and ground cover. 1. Work will be accomplished in stages so as to not expose large areas of bare soil simultaneously. 2. Limit clearing of vegetation to the minimum required for the project. B. Work activities would not be scheduled on rainy days. C. Heavy Equipment Operation. 1. All equipment shall be cleaned before entering the project area and stream, so as to reduce the risk of fine grained sediment and oils and grease from entering the stream. 2. Do not operate on wet soils when they are most susceptible to damage and erosion. 3. Points of entry to Davidson River would be designated by a hydrologist or soil scientist. 4. Do not operate heavy equipment on over-hanging stream banks. 5. Use a skilled heavy equipment operator, trained in stream restoration and construction of in-stream structures. Instruct the operator to minimize disturbance to the streambed. 6. Minimize the number of times required to enter Davidson River for the manipulation of large woody debris. 7. Cross the stream and conduct activities during periods of low flow. 8. Minimize disturbance to stream banks. 9. Install sediment fences to trap potential sediment. Stabilize any disturbed area at the end of each workday. 6 D. Re-vegetate exposed soils as soon as possible to take advantage of the loose soil conditions for seeding. 1. Exposed soil will be covered with straw mulch or biodegradable and certified weed-free erosion control matting at the end of each workday. Matting will be secured in place with staples, stakes, or live stakes of trees where conditions allow. 2. Stabilize channel banks with a temporary seed mix of wheat, millet, or similar annual grain as work is completed E. Do not move sediment trap devices until the vegetation in the disturbed areas has been established. F. Stockpile any side cast on upland sites and contain within sediment fence. G. Install sand bags or sediment fence around the project area (including staging area) to direct runoff away from the project area. H. Conduct visual inspections of Davidson River while the work is being conducted to inspect turbidity. 1. Scarify compacted soils. 7 Office Use Only: Form Version May 2002 X0060035 USAGE Action ID No. DWQ No. (If any particular item is not applicable to this project, please enter "Not Applicabie" or "Niw°.)

Name of project: Sycamore Flats Woody Debris Redistribution in Davidson River (VWP24) 2. T.I.P. Project Number or State Project Number (NCDOT Only): N/A 3. Property Identification Number (Tax PIN): N/A 4. Location County: Transylvania Nearest Town: Brevard, NC Subdivision name (include phase/lot number): N/A Directions to site (include road numbers, landmarks, etc.): From Asheville take Interstate 26E toward Asheville Airport and take the exit for State Route 280 toward Brevard. Take SR280 south to the intersection with US276; go west on US276 approximately %i mile and turn left into the Sycamore Flats Recreation Area. Park at the first set of parking spaces and walk west toward the overflow channel, which is visible from parking lot (the debris). 5. Site coordinates, if available (UTM or Lat/Long): 35° 16'34"N, 82° 42'52"W (NAD27) (Note - If project is linear, such as a road or utility line, attach a sheet that separately lists the coordinates for each crossing of a distinct water body.) 6. Property size (acres): Pisgah Ranger District (235,576 acres) 7. Nearest body of water (stream/river/sound/ocean/lake): Davidson River 8. River Basin: French Broad (Note - this must be one of North Carolina's seventeen designated major river basins. The River Basin map is available at http://h2o.enr.state.ne.us/admin/maps/.) Describe the existing conditions on the site and general land use in the vicinity of the project at the time of this application: As a result of the high flows during the hurricanes in 2004, this reach of Davidson River was blocked by large woody debris. Due to the location and arrangement of the woody debris in the main channel, more runoff than normal flows into an over-flow channel causing stream bank erosion. Also, recreational enthusiasts can not float down this reach of Davidson River without portaging around the debris. It is a safety concern as someone may not be able to get out of the river in time and may become caught in the large woody debris. 9. Describe the overall project in detail, including the type of equipment to be used: In the project area there are several whole and partial trees spanning the Davidson River. They span from the bank of the overflow channel to a large point bar on the opposite side of the river. There is some bank erosion at the overflow channel (especially at the outlet) and at the streambank immediately adjacent to the southern end of the overflow channel. These areas of erosion would be stabilized as part of this project. The largest tree spanning from the bank over to the point bar is approximately 105' long with a 30" DBH. This tree needs to be cut before it can be moved. A large excavator with a thumb would be used to move the large woody debris to the streambanks. The bole of the tree, with root wads, would be anchored to the bank via a large boulder and a cable lasso at the inlet (Site 1) and via boulders at the outlet of the overflow channel (Site 2). (See proposed action schematic.) 10. Explain the purpose of the proposed work: The intent is to re-establish the flow through the main channel of the Davidson River, stabilize stream banks in the over flow channel, and improve public safety by redistributing the large woody debris. IV. Prior Project History If jurisdictional determinations and/or permits have been requested and/or obtained for this project (including all prior phases of the same subdivision) in the past, please explain. Include the USACE Action ID Number, DWQ Project Number, application date, and date permits and certifications were issued or withdrawn. Provide photocopies of previously issued permits, certifications or other useful information.

Background Due to the storm events that occurred during the 2004 hurricane season, a woody debris jam developed and has blocked the main channel of Davidson River at the Sycamore Flats Recreational Area on the Pisgah National Forest (Figure 2). This woody debris is causing the following problems: • The debris jam is blocking part of the main channel of the Davidson River, which impedes recreational river use (e.g. canoeing and tubing) and poses a concern for public safety (Photos 1-4). • The debris jam is partially re-directing streamflow into an side-channel, causing 40 feet of stream bank erosion at the inlet (site 1) and outlet (site 2) (photos 5-8), 1 1 and posing a threat of turning more flow into the side-channel during future stormflow events.

Plan view of Sycamore Plats current condition. Channel width of Davidson River is 60 feet and channel width of the side-channel is 30 feet. The areas between State Route (SR) 27, Forest Service Road (FSR) 257, and Davidson River are forested. There is an open area by the picnic table at site 2 (outlet of side-channel). Within the red oval is a supply of large woody debris to be used at Site 2. Planned Work FSR 257 will be closed to the public during the project. Staging will occur from the northern segment of the loop road. A tracked excavator with a thumb will be used at both sites 1 and 2. The intent of the project is to re-establish the flow through the main channel of the Davidson River without eliminating the function of the side-channel, stabilize stream banks, and restore public safety through the following tasks: • Relocate the debris jam from within the main channel to the inlet of the side- channel (site 1) in order to improve flow and boater safety. • Stabilize eroding stream banks in the side-channel through the placement of large woody debris (site 2). 2 Site 1 The objective at site 1 is to open up the main channel for the majority of the river flow and for recreational users, but still allow for storm flows to access the side-channel as needed and protect the stream banks from severe erosion. To access site 1, the excavator will use a user-created trail, which will be widened to accommodate the excavator. Upon completion of the project, the trail will be rehabilitated to pre- project condition. At the inlet of the side-channel, a tracked excavator will pull the woody debris from Davidson River (Photos 1 and 2) rotating the largest tree about the root wad on the right downstream bank of the side-channel (Figure 3). The largest tree will be cut to approximately the width of the side-channel at the inlet of the side-channel. The tops of the tree and other woody debris from the jam will be placed along the banks at the upper end of the inlet to protect the streambank and provide fish habitat. Root wads of the trees will be positioned on the right downstream bank of the side-channel, facing downstream. Root wads will serve the following functions: • To provide protection for the stream banks. • To collect debris during high flow events, acting as a debris jam in the side- channel. • To provide fish cover in the side-channel and along the streambanks of the main channel of the Davidson River. A 5' to 6' boulder will be placed at the inlet of the side-channel, near the left bank. A cable will be attached to the tree and the boulder to anchor the large log in place. 3 Sycamore Flats Bank Stabilization Typical 2 I North Not to scale e 2 ,P?ted Iorid ..................... -.Site 7 Sit t W Floodplain Sycarrrore Flats :?• Picnic Area FSR 257 ... rigure J. Site plan of proposed access and woody debris relocation. Site 2 The excavator will collect woody debris from the side-channel (red oval in Figure 3) to be used at the outlet (site 2). Forty-feet of stream bank within the oval may be disturbed. A hydrologist or fish biologist will select woody debris to be used. The excavator should be able to remain on the widened user-created trail to collect the debris. The excavator will remain on the user-created trail and FSR 257 and use a new access trail to reach site 2. The new access trail will be rehabilitated. No trees will be removed. If necessary, the path will be scarified to break up compacted soils. Site 2 is characterized by an undercutting streambank that has overhanging roots and vegetation. Woody debris from the side-channel would be located to the base of this bank to provide protection during high storm events but still provide fish habitat. The exact placement of these logs will be determined by the hydrologist and fisheries biologist at the time of implementation.

Temporary BMP's To reduce erosion and sedimentation of.Davidson River, the contractor will be instructed to implement the following temporary BMP's during construction: A. Minimize the area of and degree of soil disturbance that reduces infiltration capacity and permeability and destroys protective forest floor and ground cover. 1. Work will be accomplished in stages so as to not expose large areas of bare soil simultaneously. 2. Limit clearing of vegetation to the minimum required for the project. B. Work activities would not be scheduled on rainy days. C. Heavy Equipment Operation. 1. All equipment shall be cleaned before entering the project area and stream, so as to reduce the risk of fine grained sediment and oils and grease from entering the stream. 2. Do not operate on wet soils when they are most susceptible to damage and erosion. 3. Points of entry to Davidson River would be designated by a hydrologist or soil scientist. 4. Do not operate heavy equipment on over-hanging stream banks. 5. Use a skilled heavy equipment operator, trained in stream restoration and construction of in-stream structures. Instruct the operator to minimize disturbance to the streambed. 6. Minimize the number of times required to enter Davidson River for the manipulation of large woody debris. 7. Cross the stream and conduct activities during periods of low flow. 8. Minimize disturbance to stream banks. 9. Install sediment fences to trap potential sediment. Stabilize any disturbed area at the end of each workday. 6 D. Re-vegetate exposed soils as soon as possible to take advantage of the loose soil conditions for seeding. 1. Exposed soil will be covered with straw mulch or biodegradable and certified weed-free erosion control matting at the end of each workday. Matting will be secured in place with staples, stakes, or live stakes of trees where conditions allow. 2. Stabilize channel banks with a temporary seed mix of wheat, millet, or similar annual grain as work is completed E. Do not move sediment trap devices until the vegetation in the disturbed areas has been established. F. Stockpile any side cast on upland sites and contain within sediment fence. G. Install sand bags or sediment fence around the project area (including staging area) to direct runoff away from the project area. H. Conduct visual inspections of Davidson River while the work is being conducted to inspect turbidity. 1. Scarify compacted soils. 7 Office Use Only: Form Version May 2002 Gr?-.::6005 USACE Action ID No. DWQ No. (If any particular item is not applicable to this project, please enter "Not Applicable" or 'NSA".) 1.

Site coordinates, if available (UTM or Lat/Long): 35° 16'34"N, 82° 42'52"W (NAD27) (Note - If project is linear, such as a road or utility line, attach a sheet that separately lists the coordinates for each crossing of a distinct water body.) 6. Property size (acres): Pisgah Ranger District (235,576 acres) 7. Nearest body of water (stream/river/sound/ocean/lake) Davidson River 8. River Basin: French Broad (Note - this must be one of North Carolina's seventeen designated major river basins. The River Basin map is available at http://h2o.enr.state.nc.us/admin/maps/.) Describe the existing conditions on the site and general land use in the vicinity of the project at the time of this application: As a result of the high flows during the hurricanes in 2004, this reach of Davidson River was blocked by large woody debris. Due to the location and arrangement of the woody debris in the main channel, more runoff than normal flows into an over-flow channel causing stream bank erosion. Also recreational enthusiasts can not float down this reach of Davidson River without portaging around the debris. It is a safety concern as someone may not be able to get out of the river in time and may become caught in the large woody debris. 9. Describe the overall project in detail, including the type of equipment to be used: In the project area there are several whole and partial trees spanning the Davidson River. They span from the bank of the overflow channel to a large point bar on the opposite side of the river. There is some bank erosion at the overflow channel (especially at the outlet) and at the streambank immediately adjacent to the southern end of the overflow channel. These areas of erosion would be stabilized as part of this project. The largest tree spanning from the bank over to the point bar is approximately 105' long with a 30" DBH. This tree needs to be cut before it can be moved. A large excavator with a thumb would be used to move the large woody debris to the streambanks. The bole of the tree, with root wads, would be anchored to the bank via a large boulder and a cable lasso at the inlet (Site 1) and via boulders at the outlet of the overflow channel (Site 2). (See proposed action schematic.) 10. Explain the purpose of the proposed work: The intent is to re-establish the flow through the main channel of the Davidson River, stabilize stream banks in the over flow channel, and improve public safety by redistributing the large woody debris. IV. Prior Project History If jurisdictional determinations and/or permits have been requested and/or obtained for this project (including all prior phases of the same subdivision) in the past, please explain. Include the USACE Action ID Number, DWQ Project Number, application date, and date permits and certifications were issued or withdrawn.

Vicinity map of Sycamore Flats Woody Debris Redistribution (VWP24) project. Background Due to the storm events that occurred during the 2004 hurricane season, a woody debris jam developed and has blocked the main channel of Davidson River at the Sycamore Flats Recreational Area on the Pisgah National Forest (Figure 2). This woody debris is causing the following problems: • The debris jam is blocking part of the main channel of the Davidson River, which impedes recreational river use (e.g. canoeing and tubing) and poses a concern for public safety (Photos 1-4). • The debris jam is partially re-directing streamflow into an side-channel, causing 40 feet of stream bank erosion at the inlet (site 1) and outlet (site 2) (photos 5-8), 1 and posing a threat of turning more flow into the side-channel during future stormflow events.

Plan view of Sycamore Flats current condition. Channel width of Davidson River is 60 feet and channel width of the side-channel is 30 feet. The areas between State Route (SR) 27, Forest Service Road (FSR) 257, and Davidson River are forested. There is an open area by the picnic table at site 2 (outlet of side-channel). Within the red oval is a supply of large woody debris to be used at Site 2. Planned Work FSR 257 will be closed to the public during the project. Staging will occur from the northern segment of the loop road. A tracked excavator with a thumb will be used at both sites 1 and 2. The intent of the project is to re-establish the flow through the main channel of the Davidson River without eliminating the function of the side-channel, stabilize stream banks, and restore public safety through the following tasks: • Relocate the debris jam from within the main channel to the inlet of the side- channel (site 1) in order to improve flow and boater safety. • Stabilize eroding stream banks in the side-channel through the placement of large woody debris (site 2). 2 Site I The objective at site 1 is to open up the main channel for the majority of the river flow and for recreational users, but still allow for storm flows to access the side-channel as needed and protect the stream banks from severe erosion. To access site 1, the excavator will use a user-created trail, which will be widened to accommodate the excavator. Upon completion of the project, the trail will be rehabilitated to pre- project condition. At the inlet of the side-channel, a tracked excavator will pull the woody debris from Davidson River (Photos 1 and 2) rotating the largest tree about the root wad on the right downstream bank of the side-channel (Figure 3). The largest tree will be cut to approximately the width of the side-channel at the inlet of the side-channel. The tops of the tree and other woody debris from the jam will be placed along the banks at the upper end of the inlet to protect the streambank and provide fish habitat. Root wads of the trees will be positioned on the right downstream bank of the side-channel, facing downstream. Root wads will serve the following functions: • To provide protection for the stream banks. • To collect debris during high flow events, acting as a debris jam in the side- channel. • To provide fish cover in the side-channel and along the streambanks of the main channel of the Davidson River. A 5' to 6' boulder will be placed at the inlet of the side-channel, near the left bank. A cable will be attached to the tree and the boulder to anchor the large log in place. 3 Sycamore Flats Bank Stabilization Typical 2 T North Not to scale Site2 %,Site 1 GF4 ?? ?? 6 Floodplain Sycamore Fiats V?

Site 2 The excavator will collect woody debris from the side-channel (red oval in Figure 3) to be used at the outlet (site 2). Forty-feet of stream bank within the oval may be disturbed. A hydrologist or fish biologist will select woody debris to be used. The excavator should be able to remain on the widened user-created trail to collect the debris. The excavator will remain on the user-created trail and FSR 257 and use a new access trail to reach site 2. The new access trail will be rehabilitated. No trees will be removed. If necessary, the path will be scarified to break up compacted soils. Site 2 is characterized by an undercutting streambank that has overhanging roots and vegetation. Woody debris from the side-channel would be located to the base of this bank to provide protection during high storm events but still provide fish habitat. The exact placement of these logs will be determined by the hydrologist and fisheries biologist at the time of implementation.

Temporary BMP's To reduce erosion and sedimentation of Davidson River, the contractor will be instructed to implement the following temporary BMP's during construction: A. Minimize the area of and degree of soil disturbance that reduces infiltration capacity and permeability and destroys protective forest floor and ground cover. 1. Work will be accomplished in stages so as to not expose large areas of bare soil simultaneously. 2. Limit clearing of vegetation to the minimum required for the project. B. Work activities would not be scheduled on rainy days. C. Heavy Equipment Operation. 1. All equipment shall be cleaned before entering the project area and stream, so as to reduce the risk of fine grained sediment and oils and grease from entering the stream. 2. Do not operate on wet soils when they are most susceptible to damage and erosion. 3. Points of entry to Davidson River would be designated by a hydrologist or soil scientist. 4. Do not operate heavy equipment on over-hanging stream banks. 5. Use a skilled heavy equipment operator, trained in stream restoration and construction of in-stream structures. Instruct the operator to minimize disturbance to the streambed. 6. Minimize the number of times required to enter Davidson River for the manipulation of large woody debris. 7. Cross the stream and conduct activities during periods of low flow. 8. Minimize disturbance to stream banks. 9. Install sediment fences to trap potential sediment. Stabilize any disturbed area at the end of each workday. 6 .-1 D. Re-vegetate exposed soils as soon as possible to take advantage of the loose soil conditions for seeding. 1. Exposed soil will be covered with straw mulch or biodegradable and certified weed-free erosion control matting at the end of each workday. Matting will be secured in place with staples, stakes, or live stakes of trees where conditions allow. 2. Stabilize channel banks with a temporary seed mix of wheat, millet, or similar annual grain as work is completed E. Do not move sediment trap devices until the vegetation in the disturbed areas has been established. F. Stockpile any side cast on upland sites and contain within sediment fence. G. Install sand bags or sediment fence around the project area (including staging area) to direct runoff away from the project area. H. Conduct visual inspections of Davidson River while the work is being conducted to inspect turbidity. 1. Scarify compacted soils. 7 m r m C m U ?
