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 Units Plan Location or Reference Stream 85 feet Frankum Creek 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. Frankum Creek Channel Stabilization Page 3 of 6 February 2, 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. However, Wildlife Resources Commission will not object to construction of "emergency" sites during the spawning period provided these projects are, to the extent appropriate and practical, constructed by: (1) using flow diversion structures such as sand bags, (2) placing large-sized rock toes and filter cloth backing for stabilization sites before backfilling, and (3) excavating new channel alignments in dry areas. Construction at the other non- "emergency" sites should not occur during the spawning period to minimize the potential adverse effects of multiple construction activities on trout resources in this creek. 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. Frankurn Creek Channel Stabilization Page 4 of 6 February 2, 2006 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 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 Frankum Creek Channel Stabilization Page 5 of 6 February 2, 2006 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. 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. 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. Riparian Zone Replanting 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 consistent with the Guidelines for Riparian Buffer Restoration immediately following construction. (Please see attached.) 17. 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. 18. 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. Violations of any condition herein set forth may result in revocation of this Certification and may result in criminal and/or civil penalties. The authorization to proceed with your proposed impacts or to conduct impacts to waters as depicted in your application and as authorized by this Certification, shall expire upon expiration of the 404 or CAMA Permit. If you do not accept any of the conditions of this Certification (associated with the approved wetland or stream impacts), you may ask for an adjudicatory hearing. You must act within 60 days of the date that you receive this letter. To ask for a hearing, send a written petition, which conforms to Chapter 150B of the North Carolina General Statutes to the Office of Administrative Hearings, 6714 Mail Service Center, Raleigh, Frankum Creek Channel Stabilization Page 6 of 6 February 2, 2006 N.C. 27699-6714. This certification and its conditions are final and binding unless you ask for a hearing. This letter completes the review of the Division of Water Quality under Section 401 of the Clean Water Act.

S. Army Corps of Engineers. The NCWRC has reviewed information provided by the applicant, and field biologists on our staff are familiar with habitat values of the project area. These comments are provided in accordance with provisions of the Clean Water Act of 1977 (33 U.S.C. 466 et. seq.) and the Fish and Wildlife Coordination Act (48 Stat. 401, as amended; 16 U.S.C. 661-667d). The project is to stabilize 50' of Frankum Creek using large Woody Debris (LWD) and installation of large boulders to dissipate stream energy and capture sediment. Current conditions are unstable and bare soils are indicated so these stabilization activities should improve water quality and improve aquatic habitats. Some rainbow and brown trout are known for this area. Based on the information provided by the applicant and our knowledge on the range of trout in the project area, we do not believe this project will cause significant effects to waters supporting trout. Therefore, we will not object to the project as proposed providing the activities are expeditiously done with minimal stream disturbance or without undue delay once the project begins, The area of disturbance should be minimized to the extent practicable. Thank you for the opportunity to review and comment on this project. If you have any questions regarding these comments, please contact me at 336/769-9453.

Located on the Pisgah National Forest in Caldwell County, North Carolina, this project is situated on Frankum Creek, a tributary to Mulberry Creek of the Catawba River Basin. Two sites within 0.3 miles of each other have been proposed for stabilization as a result of the 2004 storms. Site 1 on Frankum Creek has 50 feet of unstable stream bank that are bare and susceptible to erosion. Ten feet of the stream bank have already sloughed into the channel. Site 2 is where high flows created a side-channel in Frankum Creek, 150 feet upstream of its confluence with Georges Creek. A headcut in the side-channel threatens the physical integrity of Frankum Creek. This project proposes the following: Site 1: Place large woody debris (>10"DBH) with attached root wads in the channel to protect the right downstream bank; improve the physical integrity of the channel; and to enhance aquatic habitat. Site 2: Stabilize the headcut through the placement of boulders and cobble in the headcut. Place large woody debris in Frankum Creek at the inlet of the side-channel to dissipate energy and capture sediment. Approximately 85 linear feet of stream channel disturbance is expected from the project. A 404 Nationwide Permit #27 has been requested from the U.S. Army Corps of Engineers for this project, and a copy of this application has been sent to Mr. Ron Linville of the NC Wildlife Resources Commission. Enclosed are the following materials: • 5 copies of the PCN application for Section 404 permit. 5 copies of the vicinity map and site plans for the project.

Name of project: Frankum Creek Channel Stabilization (VWG16) 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: Caldwell Nearest Town: Collettesville, NC Subdivision name (include phase/lot number): N/A Directions to site (include road numbers, landmarks, etc.): Take exit 100 from Interstate 40. Drive north until you reach State Route 181, located at a busy intersection with a strip mall and several fast food restaurants. Turn left, north on State Route 181 and continue for 11 miles. You will see a white church on the right side of the road; take a right on Brown Mountain Beach Road. Continue on Brown Mountain Beach Road for 8 miles until you reach Collettesville. At the intersection turn left onto State Route 90. Continue on State Route 90 for 9 miles until you reach Globe Mountain Road. Turn right and drive approximately 2 miles. Take the first left hand turn past Globe Mountain Gap. This is Forest Service Road 188, which is unmarked and has a locked gate. Cotinue another about 0.5 miles to the Georges Creek crossing. Site 2 is located about 150 feet upstream on Frankum Creek. 5. Site coordinates, if available (UTM or Lat/Long): N/A Site 1: 36° 02' 02 N and 81° 39' 23" W Site 2: 36° V58" N 81° 39'21" W (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 waterbody.) 6. Property size (acres): Grandfather Ranger District (402,560 acres) 7. Nearest body of water (stream/river/sound/ocean/lake): Frankum Creek 8. River Basin: Catawba (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/.) 9. Describe the existing conditions on the site and general land use in the vicinity of the project at the time of this application:- Site 1: This site lies 60 feet east of FSR 188 and is on a sharp meander bend. Storms from 2004 and possibly road drainage from FSR 188 resulted in fifty-feet of the channel at the meander to become bare and susceptible to erosion. Approximately 10 feet of stream bank has already sloughed in. West of the meander is a cross-drain with a settling pond and defined swale. There may be some ground water interaction between the road and the channel that is contributing to the instability of the channel at site 1. Site 2: During the 2004 storms, a new channel on Frankum Creek was created 150 feet upstream of the confluence of Frankum and Georges Creek. This new channel re-connects with Georges Creek, upstream of the pre-storm confluence of the two streams. The new stream bed cut to bedrock and the bed of the main channel is mostly alluvium (sand and cobble). A headcut 3.0 feet in height and 1 foot wide with a scour pool has developed. Roots in the banks at the top of the headcut are keeping this headcut stable and preventing it from migrating upstream to the main channel of Frankum Creek. The difference in bed elevation between the two channels is 3.0 feet. If the headcut becomes unstable, it would migrate upstream until it reached a bedrock control. Bedrock was not found for at least a distance of 200 feet upstream of the headcut. 10. Describe the overall project in detail, including the type of equipment to be used:- Site 1: Place large woody debris 00"DBH) with attached root wads in the channel to re- direct flow away from the bare and erodible right downstream bank. Site 2: Place large rocks in the overflow channel to stabilize the headcut. Place large woody debris in Frankum Creek at the inlet of the side-channel to dissipate energy and capture sediment. 11. Explain the purpose of the proposed work:_ Site 1: Re-direct runoff away from the raw and erodible stream bank. Improve aquatic habiatat and the physical integrity of Frankum Creek. Site 2: Protect Frankum Creek from capture by the side-channel. Maintain channel integrity and reduce headcutting. 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. Describe previously approved wetland, stream and buffer impacts, along with associated mitigation (where applicable). If this is a NCDOT project, list and describe permits issued for prior segments of the same T.I.P. project, along with construction schedules. V. Future Project Plans Are any future permit requests anticipated for this project? If so, describe the anticipated work, and provide justification for the exclusion of this work from the current application. N/A VI. 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: Site 1: A tracked excavator will be operated to place large woody debris in the channel. The operation of heavy equipment will displace soils, increasing potential erosion. Some sediment will likely reach the channel, temporarily increasing turbidity near the project site until temporary erosion measures and/or riparian vegetation takes hold. The short-term increase in sediment from the project activities will be insignificant in relation to the erosion of the bare stream banks during high flows. Once riparian vegetation and woody debris takes hold streambanks should stabilize, thereby reducing streambank erosion and sedimentation of the affected streams. Site 2: Work on the headcut will be done in the channel. There will be some disturbance to the stream bed and stream bank during the placement of cobble and boulder size rock at the headcut. Impacts to Frankum Creek include a temporary increase in turbidity near the site throughout the duration of this activity. A tracked excavator will be operated to place large woody debris in the channel. The operation of heavy equipment will displace soils, increasing potential erosion. Some sediment will likely reach the channel, temporarily increasing turbidity near the project site, until temporary erosion measures and/or riparian vegetation take hold. The short-term increase in sediment from the project activities will be worth these activities. If this work is not done, the stream could headcut and downcut, delivering large volumes of sediment downstream to Frankum Creek and Mulberry Creek. 2.

Between the junctions with State Route (SR) 1368 and Forest Service Road (FSR) 4111, FSR 188 parallels Frankum Creek. The Forest Service's Engineering Department has plans to improve the FSR 188 road; such improvements should reduce sedimentation to Frankum Creek. Old route FSR 188 continues as a closed roadbed north of the intersection with FSR 4111 and parallels the creek. Storms from 2004 caused disturbance to two sites on Frankum Creek in the reach above the Georges Creek confluence (Figure 1).

Storms from 2004 and possibly road drainage from FSR 188 resulted in 50 feet of channel at the meander to become bare and susceptible to erosion. Approximately 10 feet of stream bank has already sloughed into the channel (Figure 3). West of the meander is a cross-drain with a settling pond and defined swale. There may be some ground water interaction between the road and the channel that is contributing to the instability of the channel at Site 1. Stable channel.

Site 2 During the 2004 storms, a new channel on Frankum Creek was created 150 feet upstream of the confluence of Frankum and Georges Creeks. This new channel re-connects with Georges Creek, upstream of the confluence of the two streams. The new streambed cut to bedrock while the bed of the main channel is mostly alluvium (sand and cobble). A headcut 3.0 feet in height and 1 foot wide with a scour pool has developed. Roots in the banks at the top of the headcut are keeping this headcut stable and preventing it from migrating upstream to the main channel of Frankum Creek. The difference in bed elevation between the two channels is 3.0 feet. If the headcut becomes unstable, it would migrate upstream until it reached a bedrock control. Bedrock was not found for at least a distance of 200 feet upstream of the headcut. Storm Recovery -Watershed Improvement Frankum Creek Channel Stabilization (NW6'16) Site 1- Current Condition Photo Planned Work Site 1 Four pieces of large woody debris (LWD) with attached root wads would be placed against the right downstream bank to reduce flow velocities and to protect the bank from erosion. LWD will provide aquatic habitat and help restore the physical integrity of Frankum Creek at this site (Figure 6). Additionally, 50 feet of the right streambank would be planting with riparian type vegetation, such as doghobble, dogwood, and rhododendron. i•_•i I / "., ) 4 N LL settling pored Storm Recovery -Watershed Improvement Frankum Creek Channel Stabilization (YWG16) Stable channel.

No trails would be constructed, but several small trees (DBH <6") may have to be removed to create the path. Travel to the site would likely remove some ground cover exposing bare soil. All bare soil would be covered by mulch at the end of each workday, and seeded at the end of the project. 5 Site 2 Two pieces of large woody debris (LWD) with attached root wads would be placed in the meander bend at the side-channel inlet to reduce flow to the side-channel. Also, cobble and small boulder size rock (3"-12" range in average size) would be placed at the base of the headcut at a 2:1 slope, e.g. a height of 3 feet and a length of 6 feet (Figure 7).

All bare soil would be covered by mulch at the end of each workday, and seeded at the end of the project. 6 TEMPORARY BMP's (to be applied at both sites) Because the total disturbance is less than 1 acre, NC Division of Land Quality does not require an erosion and sediment control plan. To reduce erosion and sedimentation of Frankum Creek, the contractor will be instructed to implement the following temporary BMP's: A. Minimize the area 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 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, to reduce the risk of fine grained sediment, oils, and grease from entering the stream. 2. Do not operate on wet soils when they are most susceptible to damage and erosion. 3. Do not operate heavy equipment on over-hanging stream banks. D. Install sediment fence to trap potential sediment. Stabilize any disturbed area at the end of each workday. E. 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 erosion 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. Temporary seeding will occur on all bare soil within five days of ground disturbing activities to provide long-term erosion control. 3. Stabilize channel banks with a temporary seed mix of wheat, millet, or similar annual grain as work is completed. F. Do not move sediment trap devices until vegetation in the disturbed areas has been established. G. Conduct activities during periods of low flow. H. Use a skilled heavy equipment operator, trained in stream restoration. Instruct the operator to minimize disturbance to the streambed and banks. 1. Conduct visual inspections of Frankum Creek while the work is being accomplished to inspect turbidity. 7 Office Use Only: Form Vcrsion May 2002 USACE Action ID No. DWQ No. 73 (If any particular item is not applicable to this project, please enter "Not Applicable" or "N/A".) 1.

River Basin: Catawba (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/.) 9. Describe the existing conditions on the site and general land use in the vicinity of the project at the time of this application:- Site 1: This site lies 60 feet east of FSR 188 and is on a sharp meander bend. Storms from 2004 and possibly road drainage from FSR 188 resulted in fifty-feet of the channel at the meander to become bare and susceptible to erosion. Approximately 10 feet of stream bank has already sloughed in. West of the meander is a cross-drain with a settling pond and defined swale. There may be some ground water interaction between the road and the channel that is contributing to the instability of the channel at site 1. Site 2: During the 2004 storms, a new channel on Frankum Creek was created 150 feet upstream of the confluence of Frankum and Georges Creek. This new channel re-connects with Georges Creek, upstream of the pre-storm confluence of the two streams. The new stream bed cut to bedrock and the bed of the main channel is mostly alluvium (sand and cobble). A headcut 3.0 feet in height and 1 foot wide with a scour pool has developed. Roots in the banks at the top of the headcut are keeping this headcut stable and preventing it from migrating upstream to the main channel of Frankum Creek. The difference in bed elevation between the two channels is 3.0 feet. If the headcut becomes unstable it would migrate upstream until it reached a bedrock control. Bedrock was not found for at least a distance of 200 feet upstream of the headcut. 10. Describe the overall project in detail, including the type of equipment to be used:- Site 1: Place large woody debris (10"DBH) with attached root wads in the channel to re- direct flow away from the bare and erodible right downstream bank. Site 2: Place large rocks in the overflow channel to stabilize the headcut. Place large woody debris in Frankum Creek at the inlet of the side-channel to dissipate energy and capture sediment. 11. Explain the purpose of the proposed work: Site 1: Re-direct runoff away from the raw and erodible stream bank. Improve aquatic habiatat and the physical integrity of Frankum Creek. Site 2: Protect Frankum Creek from capture by the side-channel. Maintain channel inte rity and reduce headcutting. 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 M Number, DWQ Project Number, application date, and date permits and r_3 site, until temporary erosion measures and/or riparian vegetation take hold. The short-term increase in sediment from the project activities will be worth these activities. If this work is not done, the stream could headcut and downcut, delivering large volumes of sediment downstream to Frankum Creek and Mulberry Creek. 2.

Between the junctions with State Route (SR) 1368 and Forest Service Road (FSR) 4111, FSR 188 parallels Frankum Creek. The Forest Service's Engineering Department has plans to improve the FSR 188 road; such improvements should reduce sedimentation to Frankum Creek. Old route FSR 188 continues as a closed roadbed north of the intersection with FSR 4111 and parallels the creek. Storms from 2004 caused disturbance to two sites on Frankum Creek in the reach above the Georges Creek confluence (Figure 1).

Vicinity map of the Frankum Creek channel stabilization projects. 1 Site 1 This.site lies 60 feet east of FSR 188 and is on a sharp meander bend (Figure 2). Storms from 2004 and possibly road drainage from FSR 188 resulted in 50 feet of channel at the meander to become bare and susceptible to erosion. Approximately 10 feet of stream bank has already sloughed into the channel (Figure 3). West of the meander is a cross-drain with a settling pond and defined swale. There may be some ground water interaction between the road and the channel that is contributing to the instability of the channel at Site 1. Stable channel.

Site 2 During the 2004 storms, a new channel on Frankum Creek was created 150 feet upstream of the confluence of Frankum and Georges Creeks. This new channel re-connects with Georges Creek, upstream of the confluence of the two streams. The new streambed cut to bedrock while the bed of the main channel is mostly alluvium (sand and cobble). A headcut 3.0 feet in height and 1 foot wide with a scour pool has developed. Roots in the banks at the top of the headcut are keeping this headcut stable and preventing it from migrating upstream to the main channel of Frank-um Creek. The difference in bed elevation between the two channels is 3.0 feet. If the headcut becomes unstable, it would migrate upstream until it reached a bedrock control. Bedrock was not found for at least a distance of 200 feet upstream of the headcut.

LWD will provide aquatic habitat and help restore the physical integrity of Frankum Creek at this site (Figure 6). Additionally, 50 feet of the right streambank would be planting with riparian type vegetation, such as doghobble, dogwood, and rhododendron. /_1% ) N LL Settling pond Storm Recovery -Watershed Improvement Frankum Creek Channel Stabilization (WW610) Stable channel.

Frankum Creek Channel Stabilization at Site L Access to the site would be from FSR 188. L RD would be placed in the meander bend and the bank planted Work at this site would require tracked excavator access to the right bank of Frankum Creek from FSR 188, making about a 60-foot long by 10-foot wide path of disturbance. No trails would be constructed, but several small trees (DBH <6") may have to be removed to create the path. Travel to the site would likely remove some ground cover exposing bare soil. All bare soil would be covered by mulch at the end of each workday, and seeded at the end of the project. 5 Site 2 Two pieces of large woody debris (LWD) with attached root wads would be placed in the meander bend at the side-channel inlet to reduce flow to the side-channel. Also, cobble and small boulder size rock (3"-12" range in average size) would be placed at the base of the headcut at a 2:1 slope, e.g. a height of 3 feet and a length of 6 feet (Figure 7).

No trails will be constructed, but several small trees (DBH <6") may have to be removed to create the path. Travel to the site would likely remove some ground cover exposing bare soil. All bare soil would be covered by mulch at the end of each workday, and seeded at the end of the project. 6 TEMPORARY BMP's (to be applied at both sites) Because the total disturbance is less than 1 acre, NC Division of Land Quality does not require an erosion and sediment control plan. To reduce erosion and sedimentation of Frankum Creek, the contractor will be instructed to implement the following temporary BMP's: A. Minimize the area 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 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, to reduce the risk of fine grained sediment, oils, and grease from entering the stream. 2. Do not operate on wet soils when they are most susceptible to damage and erosion. 3. Do not operate heavy equipment on over-hanging stream banks. D. Install sediment fence to trap potential sediment. Stabilize any disturbed area at the end of each workday. E. 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 erosion 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. Temporary seeding will occur on all bare soil within five days of ground disturbing activities to provide long-term erosion control. 3. Stabilize channel banks with a temporary seed mix of wheat, millet, or similar annual grain as work is completed. F. Do not move sediment trap devices until vegetation in the disturbed areas has been established. G. Conduct activities during periods of low flow. H. Use a skilled heavy equipment operator, trained in stream restoration. Instruct the operator to minimize disturbance to the streambed and banks. 1. Conduct visual inspections of Frankum Creek while the work is being accomplished to inspect turbidity. 7
