Director Division of Water Quality September 2, 2005 DWQ Project # 05-1616 Madison County Ricky McDevitt, County Manager Madison County Post Office Box 579 Marshall, NC 28753 Subject Property: Spring & Friezeland Creeks EWP (DSR - 8) Approval of 401 Water Quality Certification with Additional Conditions Dear Mr. McDevitt: You have our approval, in accordance with the attached conditions and those listed below, to place fill within or otherwise impact 2,500 feet of streams for the purpose of streambank stabilization and woody debris removal / trash removal at the subject properties, as described within your application received by the N.C. Division of Water Quality (DWQ) on July 1, 2005. After reviewing your application, we have decided that the impacts are covered by General Water Quality Certification Number(s) 3367 (3367). The Certification (s) allows you to use Nationwide Permit(s) 37 when issued by the US Army Corps of Engineers (USACE). In addition, you should obtain or otherwise comply with any other required federal, state or local permits before you go ahead with your project including (but not limited to) Erosion and Sediment Control, Non-discharge, and stormwater regulations. Also, this approval to proceed with your proposed impacts or to conduct impacts to waters as depicted in your application shall expire upon expiration of the 404 or CAMA Permit. This approval is for the purpose that you described in your application. (Nothing in this approval should be interpreted as giving permission to remove bedload material form the existing channel, nor allowing for the construction of berms which would not allow the stream access to it's floodplain.) If you change your project beyond the approval here, you must notify us and you may be required to send us a new application. If the property is sold, the new owner must be given a copy of this Certification and approval letter and is thereby responsible for complying with all conditions. If total fills for this project (now or in the future) exceed one acre of wetland or 150 linear feet of stream, compensatory mitigation may be required as described in 15A NCAC 2H .0506 (h). -This approval requires you to follow the conditions listed in the attached certification and any additional conditions listed below. The Additional Conditions of the Certification are: 401 Wetlands Certification Unit 1650 Mail Service Center, Raleigh, North Carolina 27699-1650 2321 Crabtree Boulevard, Suite 250, Raleigh, North Carolina 27604 Phone: 919-733-1786 /FAX 919-733-6893/ Internet http:l/h2o.enr.state.ne.us/ncwetlands NZ?L1 EPA An Equal Opportunity/Affirmative Action Employer- 50% Recycled/10% Post Consumer Paper Madison County: Page 2 of 6 September 2, 2005 1. 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 2,500 (feet) S rin & Friezeland 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. Madison County: Page 3 of 6 September 2, 2005 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, where applicable. However, Wildlife Resources Commission will not object to construction of Natural Resources Conservation Service "urgent and compelling" 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- "urgent and compelling" 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. Madison County: Page 4 of 6 September 2, 2005 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. 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. 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 where possible. Sandbags or other clean diversion structures should be used where possible 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. 13. Disturbed stream banks and a 25-foot vegetated zone, or the widest width that is practical under, the site conditions, should be restored where possible 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 Madison County: Page 5 of 6 September 2, 2005 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 25 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.) 17. Deed Notifications Deed notifications or similar mechanisms shall be placed on all retained jurisdictional wetlands, waters and protective woody riparian zones in order to assure compliance for future wetland, water and buffer impact. These mechanisms shall be put in place prior to impacting any wetlands, waters and/or buffers approved for impact under this Certification Approval and Authorization Certificate. A sample deed notification can be downloaded from the 401M/etlands Unit web site at http://h2o.enr.state.nc.us/ncwetiands. The text of the sample deed notification may be modified as appropriate to suit to this project. 18. Turbidity Standard The turbidity standard of 10 NTUs (Nephelometric Turbidity Units) shall not be exceeded as described in 15 A NCAC 26. .0200. Appropriate sediment and erosion control practices must be used to meet this standard. 19. 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.

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 Page 3 of 9 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: Impacts from this work will be minimized whenever possible. However to accomplish these needed repairs impacts may be realized from temporary increased turbidity, removal of aggraded bed material and temporary loss of herbaceous vegetation. Long-term impacts will be an increase in stream bank stability, stable dimension and profile, and improved vegetative cover. 2.

If a stream has no name, list as UT (unnamed tributary) to the nearest downstream named stream into which it flows. USGS maps are available through the USGS at 1-800-358-9616, or online at www.usgs.gov. Several intemet sites also allow direct download and printing of USGS maps (e.g., www.topozone.com, www.mapguest.com, etc.). Cumulative impacts (linear distance in feet) to all streams on site: 2500' 4. Individually list all open water impacts (including lakes, ponds, estuaries, sounds, Atlantic Ocean and any other water of the U.S.) below: Open Water Impact Site Number (indicate on ma) Type of Impact* Area of Impact (acres) Name Waterbody (if applicable) Type of Waterbody (lake, pond, estuary, sound, bay, ocean, etc. N/A * List each impact separately and identify temporary impacts. Impacts include, but are not limited to: fill, excavation, dredging, flooding, drainage, bulkheads, etc. 5. Pond Creation If construction of a pond is proposed, associated wetland and stream impacts should be included above in the wetland and stream impact sections. Also, the proposed pond should be described here and illustrated on any maps included with this application. Pond to be created in (check all that apply): ? uplands ? stream ? wetlands Describe the method of construction (e.g., dam/embankment, excavation, installation of draw-down valve or spillway, etc.): Page 5 of 9 Proposed use or purpose of pond (e.g., livestock watering, irrigation, aesthetic, trout pond, local stormwater requirement, etc.): Size of watershed draining to pond: Expected pond surface area: VII. 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. Access to each site will be over the most stable route possible and movement of vehicles over access routes will be minimized. Wherever possible equipment work will be done from the stream bank. Operating equipment within the channel will be done when this is the only way to accomplish needed work. Excavated material will be moved directly to trucks for hauling to disposal sites when it will not be used on site. When excavated material will be used on site it will be handled as few times as possible. Work at each site will be accomplished as quickly as possible and the site will be stabilized with erosion control matting and seeding within 5 days of site completion. Trees will be planted during the next dormant season. Equipment leaking any fluids will not be used and if leaks occur during construction the equipment will be replaced or repaired immediately. Sediment and erosion control measures, including silt fence, stoned entrances, protected stock pile areas, diversions and check dams, will be employed to minimize sediment movement off site. 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. Any application Page 6 of 9 lacking a required mitigation plan or NCWRP concurrence shall be placed on hold as incomplete. An applicant may also choose to review the current guidelines for stream restoration in DWQ's Draft Technical Guide for Stream Work in North Carolina, available at hgp://h2o.enr.state.nc.us/ncwetlands/strrngide.html. 1. Provide a brief description of the proposed mitigation plan. The description should provide as much information as possible, including, but not limited to: site location (attach directions and/or map, if offsite), affected stream and river basin, type and amount (acreage/linear feet) of mitigation proposed (restoration, enhancement, creation, or preservation), a plan view, preservation mechanism (e.g., deed restrictions, conservation easement, etc.), and a description of the current site conditions and proposed method of construction. Please attach a separate sheet if more space is needed. N/A 2. Mitigation may also be made by payment into the North Carolina Wetlands Restoration Program (NCWRP). Please note it is the applicant's responsibility to contact the NCWRP at (919) 733-5208 to determine availability and to request written approval of mitigation prior to submittal of a PCN.

A literature search for each planed practice location took place in the Archaeological Map room of the NC Office of State Archaeology. Each location was reviewed for the potential of NRCS planned activities to effect cultural resources (CR's). In addition, photographs of the APE's were often reviewed and discussions were held with knowledgeable field office staff and/or the engineering staff in order to determine the potential of planned activities to effect CR's at each EWP practice location. Each practice location received a ranking of a low, medium or high potential to effect CR's. All EWP practice locations receiving a medium or high ranking to effect cultural resources were archeologically surveyed by the NRCS CRS. Archaeological survey procedures included reconnaissance survey of all visible soils in the area including river bank profiles and shovel testing. All shovel tested soils were screened through'/4 inch hardware mesh. The following Excel file list of EWP locations includes a statement describing the results of this survey work. The NRCS CRS maintains the field work details of the archaeological survey at each APE. Any questions concerning the results of these survey results as listed below should contact the NRCS CRS for further explanation.

The following comments are provided in accordance with the Migratory Bird Treaty Act (16 U.S.C. 703, et seq.); section 7 of the Endangered Species Act of 1973, as amended (16 U.S.C. 1531-1543) (Act); and the Fish and Wildlife Coordination Act (16 U.S.C. 661 et seq.). Emergency Watershed Protection. Flood damage to stream banks and channels occurred in the watersheds of several streams in western North Carolina from extreme flows during and following extensive rainfall associated with two storms in September 2004. Assistance to North Carolina counties is proposed under the EWP Program of the Natural Resources Conservation Service (MRCS). According to 7 CFR, Part 624.2, "The objective of the EWP program is to assist in relieving imminent hazards to life and property from floods and the products of erosion created by natural disasters that cause a sudden impairment of a watershed." We previously provided the following recommendations to minimize and avoid potential adverse impacts to fish and wildlife resources: • Stream Channel and Bank Reconstruction/Restoration Activities. These guidelines are the criteria that we believe need to be met in order to minimize environmental impacts. If an applicant agrees to follow these guidelines, this letter may serve as evidence of consultation under the FWCA, and further consultation with us under the FWCA will not be necessary (unless the NRCS desires additional input). • Recommended Native Plant Species for Stream Restoration in North Carolina. We recommend the use of native plants in restoration and erosion-control efforts. This document provided a list of suitable species and sources. We found the maps helpful for pinpointing the location of each proposed EWP project site. We do note that each of the sites is located within the French Broad River basin. Endangered Species. According to our records and a review of the information you provided, no listed species or their habitats occur on the sites described. We concur with the determination that the activities proposed at these sites will not affect endangered or threatened species or their habitats. Therefore, we believe the requirements under section 7 of the Act are fulfilled. However, obligations under section 7 of the Act must be reconsidered if. (1) new information reveals impacts of this identified action that may affect listed species or critical habitat in a manner not previously considered, (2) this action is subsequently modified in a manner that was not considered in this review, or (3) a new species is listed or critical habitat is determined that may be affected by the identified action. If we can be of assistance or if you have any questions, please do not hesitate to contact Mr. Mark A. Cantrell of our staff at 828/258-3939, Ext. 227.

Highway 63 between the community of Trust and the top of Doggett Mountain. These sites are being described together in one design plan because they are all small sites (impacting less than 100 linear feet) and the needs and repair proposals are similar for each site. Site 2 is located .85 miles from Trust on NC Highway 63 and is on the property of Ray L. and Dale Hipps (35.7455°N, 82.8590°W). This site consists of an eroding meander bend that is slightly over wide (Figure 1). Some sand and cobble have been deposited at this site and the deposition is causing erosion of the left bank. To repair this site we plan to excavate the aggraded material and develop the proposed cross-section that is attached. Some of the excavated material will be placed on the right bank to better define the point bar and the remaining material will be hauled to a high ground disposal site. The left bank will be protected by installing a vane at the lower end of the eroding bend. The banks shall be smoothed, seeded, and matted. Woody vegetation shall be installed during the dormant season. Site 3 is located 1.17 miles from Trust on NC Highway 63 and is on the property of Mrs. Hattie Webb (35.7421°N, 82.8554°W). This site consists of an over wide reach of approximately 60 feet in length which appears to have been a riffle prior to the storm (Figure 2-3). There were trees above and below this site, which indicates that the channel widened during the storm due to the lack of stabilizing tree roots in the right bank. Once it became over wide, bed material was deposited causing the channel to aggrade. To repair this site we plan to excavate the sand and cobble and develop the proposed cross-section that is attached. Some of the excavated material will be placed on the right bank to narrow the channel, to back fill the constructed riffle and the remaining material will be hauled to a high ground disposal site. We propose to build a constructed riffle at this site to narrow the channel to the proper width and to provide grade control. The banks shall be smoothed, seeded, and matted. Woody vegetation shall be installed during the dormant season. Site 6 is located 1.73 miles from Trust on NC Highway 63 and is on the property of Ms. Patsy Buckner (35.7391°N, 82.8489°W). This site consists of a slight bend where the channel is very close to the road and has eroded into the road shoulder (Figure 4-6). Some cobble and small boulders have been deposited in the eroded area. Just downstream of the eroded area is an accumulation of woody debris. This debris may have blocked the channel during the storm and caused storm flows to be directed into the left bank causing erosion. To repair this site we plan to install a vane at the upper end of the eroding bend and to place a boulder toe along the eroding road shoulder. Fill material will placed between the boulders and existing road shoulder to develop a flatter slope. The woody debris will also be removed to open the channel and reduce the potential for a future channel blockage. The banks shall be smoothed, seeded, and matted. Woody vegetation shall be installed during the dormant season. Site 7 is located 1.93 miles from Trust on NC Highway 63 and is on the property of William J. and Roberta S. Barlow (35.7413°N, 82.8474°W). This site consists of a wide meander bend that has excessive deposition of sand and cobble through the bend (Figure 7-8). This has resulted in at least three separate channels through the bend. To repair this site we plan to excavate the aggraded material and develop the proposed cross-section that is attached. Some of the excavated material will be placed on the right bank to better define the point bar and the remaining material will be hauled to a high ground disposal site. The banks at this site are well vegetated and will not be disturbed by these repair plans. Site 8 is located 2.36 miles from Trust on NC Highway 63 and is on the property of William J. and Roberta S. Barlow (35.7414°N, 82.8424°W). This site consists of a short reach were woody debris caused a blockage in the channel (Figure 9-12). Sand and cobble were deposited upstream of the blockage as water backed up. To repair this site we plan to excavate the aggraded material and develop the proposed cross-section that is attached. The excavated material will be hauled to a high ground disposal site. Existing banks are well vegetated and every effort will be made to avoid damaging bank vegetation in this area. Where vegetation has to be removed the banks shall be smoothed, seeded, and matted. Woody vegetation shall be installed during the dormant season.

The site can be accessed from N.C. Highway 63 which runs beside the stream for its entire length. This property belongs to Mrs. Hattie Webb who lives in Mountain Home, Tennessee. The right stream bank has been a pasture in the past but presently is undergoing secondary secession. The top of the left stream bank is forested for a part of the reach and is a pasture for the remaining length. During the fall 2004 floods, the channel became blocked by large woody debris and cobble. The right bank height was at or just above the bankfull elevation. When the channel became blocked, an avulsion occurred that caused water to flow out of the existing channel and across the floodplain. This has continued since the storms and the channel is now braided over a wide area, causing a number of headcuts. The abandoned channel has only a small amount of water flowing through it. The initial large blockage remains and a second depositional area exists approximately 200 feet downstream. Upstream of the first blockage is a short 50 foot reach of eroding, vertical left bank that may have been the result of water pooling upstream of the blockage. The repair approach at this site will be to remove the aggraded sand and cobble, and stabilize the stream riparian zone so that it resists future flood damage. Access will be difficult at this area, but will be gained from the upstream pasture along the right bank to those areas that need repair. The aggraded material will be removed to increase channel capacity. Channel dimension will be adjusted to match the cross-section shown on the attached proposed typical cross-section. This should reduce the width/depth ratio from the existing high values of 245 (XS2) and 31(XS4) to the more stable range of 16 to 14, respectively. Cross vanes will be constructed in both areas to protect the repaired banks, drop grade, move flows to the center of the channel and provide grade control. Where gullies or areas lower than the bankfull elevation have developed in the floodplain, excavated material will be graded into these areas to increase the elevation to at least the bankfull elevation. Disturbed stream banks will be sloped to match existing banks, seeded and matted with coir matting. Coir matting may not be used if existing trees do not allow. In this case disturbed ground will only be mulched with straw. Barerooted trees and live-stake vegetation will be planted during the dormant season.

EWP-Madison County, North Carolina DSR 8 - Friezeland Creek - Site 5 French Broad River Basin 4.6 square mile watershed 35.7378°N, 82.8511-W ? 10 Scope of Work This site is on Friezeland Creek, 1.5 miles upstream of the confluence of Friezeland Creek and Spring Creek. The site can be accessed from N.C. Highway 63 which runs beside the stream for its entire length. This site encompasses property owned by two separate landowners with the right bank being owned by Ms. Patsy Buckner who lives on site and the left bank being owned by Paul R. and Marjorie Daigle of Sugar Land, Texas. The right bank is used to pasture cattle during the winter and the left bank is forested. During the fall 2004 floods, the channel at this site experienced erosion and deposition as flood waters eroded stream banks. The project reach measures approximately 1000 linear feet; however, only the upstream 300 feet and the downstream 300 feet require repair. In both of these areas existing land uses had removed stabilizing vegetation. In each case the storm flows began eroding and cutting back these unprotected banks and the cobble and sand that were major components of the banks were deposited downstream. Additionally, as the stream became overly wide, additional sand and cobble that the stream had been transporting was deposited. At the upstream area this resulted in an eroding left bank and a long depositional bar on the right bank. Towards the end of this reach, the thalwag transitions to the right bank causing some minor erosion, with deposition on the left bank. Below this upper area the channel goes through a forested reach where the channel is stable. Below this forested reach the left bank has eroded back several feet and the cobble eroded from this bank has been deposited in mid-channel. Flows off of this deposition have eroded the right bank back a few feet into the existing pasture and left the lower reach as one long riffle with a high width/depth ratio. The repair approach at this site will be to remove the aggraded sand and cobble, and stabilize the stream riparian zone so that it resists future flood damage. Channel dimension will be adjusted to match that shown on the proposed typical cross-sections. The aggraded material will be removed from the proposed channel to increase channel capacity and used to create the bankfull floodplain. This will reduce the width/depth ratio from the existing high values (>30) to a more stable 15 (average). Vanes will be used to protect repaired stream banks and move higher flows to the center of the channel. At the downstream area a constructed riffle will be built over the steeper reach below the eroding left bank. This will reduce the amount of material that will need to be excavated, stabilize the grade, narrow the channel and protect the banks. At the downstream end of this area a cross vane will be installed to protect the repaired banks, to center the thalwag and to reduce energy through creation of pool habitat. Disturbed stream banks will be sloped to match existing banks, seeded and matted with coir matting. Barerooted trees and live-stake vegetation will be planted during the dormant season.

The site can be accessed from either N.C. Highway 63 or N.C. Highway 209. This site is on property owned by the Eakes Family, LP; represented by family members living on the property, Todd Glasser and Carmen Eakes Glasser. Their parcel includes both stream banks for the two reaches where work is proposed. Both streams and their confluence are within the landowner's yard and the banks are grassed and mowed. This site includes a reach along Friezeland Creek and a reach along Spring Creek which extends upstream and slightly downstream of the confluence with Friezeland Creek. The Spring Creek reach is relatively flat and somewhat over wide. During the fall 2004 floods, the Spring Creek channel at this site experienced aggradation as flood waters deposited sand and cobble along the stream bed. Past floods have also had this result and previous landowners have dredged the channel and deposited cobble on the banks throughout this project reach. This reach has a low slope (1%) compared to Friezeland Creek (3%) and the Spring Creek channel above and below this site (app. 2 to 3%). The Friezeland Creek reach has a greater slope and is causing scouring around the foundation of the landowners access bridge. The repair approach at this site will be to install vanes and adjust the cross-section dimension to increase sediment transport competency on this reach of Spring Creek and to raise the grade along the bridge foundation on Friezeland Creek. Two cross vanes will be installed on Spring Creek as shown on the attached site map. One will be placed upstream of the confluence and one will be placed below the confluence. These structures, combined with cross-section shaping, should reduce channel aggradation. A third cross vane will be installed just below the bridge on Friezeland Creek. The invert of the cross vane will be set just above the foundation of the bridge. The channel upstream of this structure will be filled with native channel material removed from other EWP sites and brought to grade with the cross vane and bridge foundation. Disturbed stream banks will be sloped to match existing banks, seeded and mulched. Barerooted trees and live-stake vegetation will be planted during the dormant season.

The left bank of the main problem area of the reach belongs to John Burwell of Madison County and the right bank belongs to Ada Decker of Rogersville, TN. The right bank of the very upper section of the reach belongs to Jack Price and the left to Ethel Kirkpatrick. The right side of the stream is wooded and the left side is grown up with tall grass. Coarse sediment deposits from the hurricanes of 2004 have reduced the capacity of this section of stream so that during less than bankfull storm events water flows into the flood plain and onto NC 209. The design approach at this site is to remove the coarse sediment deposits and adjust channel dimensions to provide a cross-sectional area typical of a stream with this size watershed. A J- hook shall be installed to protect the left bank and direct flows through the meander. All disturbed banks shall be seeded and matted. Deep rooted woody vegetation shall be planted during the dormant season.

The Contractor shall minimize vegetation disturbance by only working on the stream bank and channel that is in need of repair. Existing buffers shall not be disturbed unless directed by the designer. 2. The Contractor shall only enter the stream channel as shown on the plans or directed by the designer. These stream accesses shall conform to the design standards shown in the attached detail drawings. Timber mats may be used as a substitute for rock per the approval of the designer. 3. The Contractor shall limit all bank and channel disturbance to activities that can be completed by the end of each working day such that the work would remain in place during an overnight storm event. 4. All equipment and uninstalled materials shall be removed from the channel at the end of each working day and secured safely from potential out-of-bank flow events that may occur prior to performing additional work. 5. Graded stream banks shall be stabilized with temporary and permanent seed and coir fiber matting at the end of each working day. Seeding and coir fiber matting specifications are included with this plan. 6. Stockpiles shall remain at least fifteen feet from flowing water and outside of the top of bank. Silt fence shall be placed at the base of the stockpile between the stockpile and the channel and must function to receive stockpile runoff before entering the channel. Silt fence shall conform to design standards shown in the detail drawings. 7. Temporary vegetation and permanent herbaceous vegetation shall be established on all disturbed areas not already stabilized with matting, within five days after construction is completed. 8. Permanent woody vegetations species are listed in the vegetation specifications; planting details are also included. Buck Engineering 1 of 8 River Works TECHNICAL SPECIFICATION Vegetation Planting General Seeding Seeding should be done immediately upon completion of final grading. Apply seed prior to installing matting. Prepare the soil surface so that it is smooth and free from stones, clods, or debris that will prevent the contact of the matting with the soil. Fertilizer and lime are generally not necessary on most projects, particularly not on sites that have been used for agriculture production or cattle grazing. Urban soils may require amendments. Seed should be broadcast with a centrifugal seeder or by hand, at the full rate along stream banks and in stockpile areas. In all areas where permanent seeding is used in addition to the temporary seed, mixing of the seed for broadcasting is acceptable. Seed and amendments (if needed) should be covered to a depth of 1/2 to 1 inch with soil by using a hand rake, drag or other tillage equipment. Seeding may also be done with a hydroseeder. Wood cellulose fiber will not be acceptable as a substitute for straw mulch. A suitable tracer shall be used to clearly identify areas hydroseeded. A minimum of 500 lbs. per acre of wood cellulose fiber or a non-toxic water base dye may be used as a tracer. Seed shall not remain in water containing fertilizer more than 45 minutes before being used. All products used to hydroseed shall be non-toxic to aquatic organisms. Temporary Seeding For temporary seeding, apply the following vegetation at the listed rates and times. Temporary Seeding (September to March): Rye grain 3 lbs per 1,000 sq ft or 130 lbs per acre Temporary Seeding (April to August): Foxtail Millet 1 lb per 1,000 sq ft or 401bs per acre A combination of the two temporary seed types shall be used during the boundary months of March, April, August and September to ensure survival. In all disturbed areas where no permanent seed is being used (i.e. yard or agricultural field) and temporary seed is not desired at the higher rate, broadcast temporary seed at the lower rate of approximately 1/2 the full lbs/acre stocking rate. When used in conjunction with permanent seed mix, apply at %i the full lbs/acre rate. Permanent Seeding Permanent seeding will be accomplished using the mix listed below: Buck Engineering 2 of 8 River Works Riparian Seed List Scientific name Agrostis alba Carex vulpinoidea Elymus virginicus Juncus ejfzsus Panicum clandestinum Polygonum pennsylvanicum Bidens frondosa Coreopsis lancolata Cassia fasciculata Verbesina alternifolia Common Name % of Mix Redtop 15% Fox Sedge 10% Virginia Wild Rye 20% Soft Rush 5% Deer Tongue 15% Smartweed 5% Beggers Ticks 5% Lance leafed Coreopsis 15% Partridge Pea 5% W ingstem 5% Seed at full rate of 15 lbs/acre along stream banks and in any stream buffer and wetland areas. Riparian Buffers Trees and Shrubs Trees and shrubs will be used to provide permanent vegetation for EWP repair sites. Species used shall be selected from the following list: Shrub and Small Trees Scientific name Common name Salix sericea Silky Willow Xanthorhiza simplicissima Yellowroot Physocarpus opulifolius Ninebark Cornus amonum Silky Dogwood Hamamelis virginiana Witch-hazel Carpinus caroliniana Ironwood Corylus americana Hazel-nut Alnus serrulata Tag Alder Ostrya virginiana Hornbeam Spirea tomentosa Hardback Rhododendron arborescens Smooth Azalea Rhododendron maximum Rosebay Rhododendron Cephalanthus occidentalis Button Bush Itea virginica Virginia Sweetspire Calycanthus floridus Sweet Shrub Leucothoe axillaris var, editorum Dog Hobble Hydrangea arborescens Mountain Hydrangea Sambucus canadensis Elderberry Buck Engineering 3 of 8 River Works LargeTrees Scientific name Common name Aesculus octandra Buckeye Tsuga canadensis Canadian Hemlock Platanus occidentalis Sycamore Acer rubrum Red Maple Quercus alba White Oak Quercus rubaa Red Oak Liriodendron tulipifera Tulip Poplar Tsuga carolinianum Carolina Hemlock Betula lenta Cherry Birch Trees shall be planted as either bare rooted or containerized material. Trees should be planted at a rate of 400 stems/acre (roughly 10 feet on center) where EWP repairs have been accomplished. Planting of this material will be done during the dormant season (late fall and winter of 2005-2006). Refer to the attached details and specifications for more information. Stream banks Live Staking Species used for live staking shall be taken from the following species: Scientific name Common name Cornus amomum Silky Dogwood Salix sericea Silky Willow Sambucus canadensis' Elderberry Cephalanthus occidentalis Buttonbush Salix nigra Black Willow Stake at 2-3 foot spacing on the outside of all meander bends. Stake at 6-7 foot spacing on the inside of meander bends and all tangent sections. Note this is appropriate for most rural systems. Urban or flashy systems should be staked at higher rates. Utilize as diverse a species group as feasible and make sure that black willow constitutes less than 25% of total stakes used. Containerized Plants: Containerized shrub material may also be used on the stream banks to increase the diversity. Applications and spacing should reflect that of live stake material. Mulching Mulching shall be used to provide temporary protection of soil surfaces from erosion. Mulching should be performed within 48 hours of seeding. Grain straw mulch should be applied on seeded areas at a rate of 75 bales per acre. Apply mulch uniformly. Buck Engineering 4 of 8 River Works Erosion Control Matting Ecostakes Provide wooden stake not less than 12 in. (300 mm) in length with a notch cut 1 in. (25 mm) from the top. These stakes shall be used to stake the matting along the slopes. Wooden 3 ft. stakes spaced approximately 4 ft. apart shall be used to secure the matting at the toe of slope. The toe stakes shall have a minimum 1-inch by 1-inch cross-section and shall be designed so that the matting can not slide past the exposed end of the stake. Refer to the attached details and specifications for EAT work for more information. Coir Fiber Matting The erosion control matting shall be a machine-produced mat of 100% coconut fiber with the following properties: Matrix 100% Coconut Fiber Weight 20 oz/SY (678 gm/m2) Tensile Strength 1348 x 626 lb/ft minimum (1650.5 x 766.5 kg/m) Elongation 34% x 38% Open Area (measured) 50% Thickness 0.30 in minimum (7.6 mm) Flexibility (mg -cm) 65030 x 29590 Recommended Flow 11 feet/second (3.35 m/s) Size 6.6 x 164 ft (120 SY) or (100 SM) "C" Factor 0.002 Place the coir fiber matting immediately upon final grading. Provide a smooth soil surface free from stones, clods, or debris that will prevent the contact of the matting with the soil. Apply seed prior to installing matting. Begin at the bottom of the slope by anchoring the matting in a 6-inch (15 cm) deep by 6-inch (15 cm) wide trench. Backfill and compact the trench after staking. Walking backward down the stream, allow the matting to unroll slowly; ideally the matting roll will rest against your shin as you walk. Stake the matting according to recommended stake pattern for specific product and slope. (See stake pattern guide that comes with the product.) Place matting in full contact with the soil. The edges of the parallel matting must be staked with approximately 2 inches (5 cm) of overlap such that the edge of the downstream matting is under the one just upstream. When matting must be spliced down the slope, place matting end over end (shingle style) with approximately 6 inches overlap. Drive stakes through the overlapped area. Place stakes across the matting at ends, junctions and trenches approximately 1.3 ft apart. Place stakes along the outer edges, down the center of each strip of matting and along all lapped edges approximately 2 ft apart. Cut excess matting and anchor at the end of the slope. Buck Engineering 5 of 8 River Works Temporary Stream Access Ramps Stream access ramps shall be constructed using either rock or timber mats in locations as shown on the plans or as directed. Grading shall be performed only to the extent needed to form a stable ramp connecting the stream bank grade to the streambed. The Contractor shall determine the appropriate number of timber mats and ramp angle according to the equipment that will be using the ramp. Stream access ramps are temporary and shall be removed and the areas restored to their original state when they are no longer needed or permanent measures are installed. Sediment Fence Geotextile sediment fences shall be used to trap sediment from areas of limited runoff. Sediment fences shall be properly anchored to prevent erosion under them. These works are temporary and shall be removed and the areas restored to their original state when they are no longer needed or permanent measures are installed. Locations for sediment filters are shown on the plans. Refer to sediment fence specifications (6.62) in the NC Erosion and Sediment Control Planning and Design Manual for material and installation requirements. Gravel Construction Entrance/Exit Temporary gravel construction entrances shall be constructed as shown on the plans and according to specification 6.06 of the NC Erosion and Sediment Control Planning and Design Manual. In-stream Structures In-stream structures include w-weirs, cross vanes, j-hook vanes, log vanes, and wing deflectors. The quantity of in-stream structures to be constructed shall follow approved plans, but may be affected by conditions encountered during construction Boulders used for in-stream structures shall be relatively flat on either side in the same dimension, preferably the long dimension, and must have relatively smooth ends. No more than 5% of the boulders shall be smaller than 3'x2'x2'. Boulders larger than 6'x4'x3' shall be permitted. Boulders found on-site and approved for use by the Developer will be used to the extent feasible. The Contractor shall construct in-stream structures with equipment capable of moving and accurately placing boulders of approximate dimensions 6'x4'x3'. If suitable for backfill, excavated material shall be placed on the upstream side of structures or as directed. Unless otherwise approved by the Developer, excavation to prepare the subgrade for the installation of in-stream structures shall be consecutive and continuous. Once the excavation of a structure has begun, the structure shall be completed by the end of the workday. All equipment shall be removed from the stream at the end of each workday. Any accumulation of sediment in the channel shall be cleaned as needed during construction and at the end of construction. No separate payment will be made for this clean-up work. Buck Engineering 6 of 8 River Works Construction Sequence of Events Construction shall be performed at the EWP site in accordance with the plans and in general accordance with the following sequence: 1. Mobilize equipment and materials to the site. 2. Set up construction access pads, staging areas, haul roads, and silt fences. 3. Install stream access ramps. 4. Excavate and grade banks and construct in-stream structures. 5. Seed and mat graded banks and immediately upon reaching final grades. 6.

Dear Ms. Karoly: Enclosed with this letter are four (4) copies of the Pre-Construction Notification, site plans, erosion control plan, construction details and specifications and other pertinent information that are being submitted for regulatory review. I spoke to Kevin Barnett and he told me to send the fifth copy directly to him to save your office the time and resources of forwarding it back to him. We have also submitted this information to the U.S. Army Corps of Engineers, N.C. Wildlife Resources Commission and N.C. Land Quality Section for their review. We are providing this information for your department's consideration and comments relative to 401 permitting. We believe that these sites are exempt from the need for an approved erosion control plan because sites are either on land used for agriculture or will impact less than 1 acre. Even though an erosion control plan is not required we have completed one for our work in Madison County and have attached these guidelines. We also don't believe that a trout buffer waiver is required for these projects since an erosion control plan is not required; however, Spring Creek is designated as Hatchery Supported by the N.C. Wildlife Resources Commission and Friezeland Creek may support wild trout. Because fall and winter are the more sensitive seasons for trout, we are attempting to get permitting issues completed and proposed repair work done before October 15, 2005. We believe the quick repair of these damaged stream sites will result in an improvement to existing aquatic habitat and will promote more stable channel conditions in the long-term. Thank you for your consideration of this request. If you have any questions, please contact me as soon as possible at 828-350-1408 ext. 2002 or 828-734-7445.
