Ross Jr., Secretary North Carolina Department of Environment and Natural Resources Alan W. Klimek, P.E. Director Division of Water Quality July 25, 2005 Project # 05-1270 Robert Wiseman, County Manager ?W r a Avery County Avery County AUG 1 - 2.005 Post Office Box 640 Newland, NC 28657 DENR - WATERUUALITY WETLANDS AND STORMWATER BRANCH Subject Property: Linville River, Crossnore Creek, & Stamey Branch EWP (DSR - CrsC-1 & 2, LR-2, 3, & 5, & SBA) Approval of 401 Water Quality Certification with Additional Conditions Dear Mr. Wiseman: You have our approval, in accordance with the attached conditions and those listed below, to place fill within or otherwise impact 1,560 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 14, 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 from the existing channel, nor allowing for the construction of berms which would not allow the stream access to it's floodplain.) As "stable" and "pre-storm" are not interchangeable terms, all work must be to ensure stability, regardless of channel location. Additionally, channels cannot be returned to it's pre-storm location unless there is documented instability is submitted and approved as part of the application package. 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. 101 Wetlands Certification Unit 1650 Mail Service Center, Raleigh, North Carolina 27699-1650 ?321 Crabtree Boulevard, Suite 250, Raleigh, North Carolina 27604 'hone: 919-733-17861 FAX 919-733-6893 / Intemet: http://h2o.enr.state.nc.us/ncwetlands IPA >n Equal Opportunity/Affirmative Action Employer - 50% Recycledl10% Post Consumer Paper The Additional Conditions of the Certification are: 1. Impacts Approved Amount Approved (Units) Plan Location or Reference Stream 1,560 feet Linville River & Tribs Avery Co y: Page 21t 6 July 25, 005 I 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: 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 Ibe 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, 'he requirements specified in the most recent version of the North Carol na 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 rip rian areas beyond the footprint of the impacts depicted in the Pre-Construction Notification. All construction activities, including the design, installation, opera ion, and maintenance of sediment and erosion control Best Management Practices, 1 Avery County: Page 3 of 6 July 25, 2005 shall be performed so that no violations of state water quality standards, statutes, or rules occur. 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, where applicable, 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. Avery County: Page 4 of 6 July 25, 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 natur I and more stable stream channel dimensions. Stream bed materials are unstabl in flowing-water situations and are unsuitable for bank stabilization. In stream dredging has catastrophic effects on aquatic life and disturbance of the natural fora 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 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 tern Avery County: Page 5 of 6 July 25, 2005 (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 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 401/Wetlands Unit web site at http://h2o.enr.state.nc.us/ncwetlands. 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 2B. .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. Avery County: Page 6 of 6 July 25, 2005 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, N.C. 27699-6714.

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. Each impact must be listed separately in the tables below (e.g., culvert installation should be listed separately from riprap dissipater pads). Be sure to indicate if an impact is temporary. All proposed impacts, permanent and temporary, must be listed, and must be labeled and clearly identifiable on an Page 3 of 9 accompanying site plan. All wetlands and waters, and all streams (intermittent and perennial) should 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 temporaU increased turbidity and short-term loss of herbaceous vegetation. Long-term impacts will be an increase in stream bank, bridge, and building stabili , stable dimension, and improved vegetative cover. 2. Individually list wetland impacts. Types of impacts include, but are not 'limited to mechanized clearing, grading, fill, excavation, flooding, ditching/drainage, etc. For dams, senarately list impacts due to both structure and flooding.

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 1 inimized. Wherever possible eauipment work will be done from the stream bank. Operatina leauinment 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 January 15, 2002, 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 fiinction and relative value of th impacted aquatic resource will be considered in determining acceptability of appropriate and racticable 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 lacking a required mitigation plan or NCEEP concurrence shall be placed on hold as incomplete. An applicant may also choose to review the current guidelines for stream restoration I,in DWQ's Page 6 of 9 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 J Draft Technical Guide for Stream Work in North Carolina, available at http://h2o.enr.state.nc.us/ncwetlands/strmgide.htmi. 1.

Buck Engineering will be providing engineering services and pemutting assistance in support of the Emergency Watershed Protection Program. In this contractual relationship, Buck Engineering will act as the County's agent for the purpose of accomplishing this work. Specifically, employees of Buck Engineering may take those actions necessary to obtain environmental permits from the U. S. Army Corps of Engineers, N. C. Division of Water Quality, and N. C.

Latitude 36.0218320 Lonqitude -81.930355 Length of Approximately 1728 feet Waterbody: Crossnore Creek Assessment: Debris removal Channel realignment X Seeding X Bank sloping X In-stream structures _ Adjust channel dimension X Bank stabilization X Riparian planting Summary Evaluation of Conditions: The First Baptist Church on the left bank had already done some in-stream work. They have fortified the left bank with concrete barriers and filled in behind them in the are adjacent to their parking lot. Downstream from this area both the right and left banks are vertical and eroding. Upstream from the church both banks are also vertical and eroding. Upstream from the church there is a shed on top of the bank that is threatening to fall into the channel. The DSR states that this site threatens 10 homes, a church, and one business. The total repair cost or damage to these properties is $425,000. The original DSR cost estimate for fixing this site was $5,300. The revised cost estimate is $21,570. The shed on the right bank that is threatening to fall into the channel should be moved to protect the structure and to allow the banks to be sloped for stabilization. 1100 feet of banks should be sloped up and downstream from the church as shown by the design details. Note the areas skipped to save trees. These banks should be sloped to a 2.5:1 to 3:1 ratio. They should also be seeded, matted, and planted for stabilization. The banks should be planted from the water surface to the top of the bank (approximately 3 feet in height) with live stakes at 3 foot spacing on the outside of meander bends (270 ft, 0.05 ac) and 6 foot spacing on the inside of meander bends or in straight sections (830 ft, 0.16 ac). A total of 465 live stakes will be needed. Though a 25 foot riparian buffer is desirable, it is unlikely that the landowners will agree to it as this buffer would take up a great deal of their backyards. Therefore, the left banks will not be included in the riparian buffer calculations, and will result in a more conservative cost estimate. To achieve a planting rate of 680stemstacre in the riparian zone on the right bank (680 ft, 0.39 ac), 265 stems will be needed. The entire 0.60 acres should be seeded using both temporary and permanent seeding mixes. 8.71bs of each type of seed will be needed to achieve an application rate of 15lbs/acre. 3862 square yards of coconut coir matting will be required to cover the banks.

The problem is similar at each location, where banks have eroded and lack vegetation. Site 1 is located between Meadow Street and New Street. For approximately 55 feet the right bank has eroded and is lacking vegetation. This erosion is located in the front yard of a home and directly across the creek from a large brown metal storage building. Site 2 is located directly downstream of New Street. Both the right bank and the left bank have eroded and lack vegetation. The pipe is also elevated above the bed of the stream by approximately 12 inches. Site 3 is located between two driveways. The pipe extending from the upstream driveway has eroded the right bank and the bank is lacking vegetation. Further downstream the left bank is eroded in places and is lacking adequate vegetation. According to the Economic Evaluation the project will protect thee homes valued at $250,000. According to the Damage Survey Report the installation cost of emergency work would be $6,500. The recommendations for improvements listed below would cost approximately $16,270. Site 1: Where the erosion occurs, the 55 foot eroded right bank should be sloped back approximately 2.5-3:1 slope (0.01 acres). The area should also be seeded and planted for stabilization. A total of 13 live stakes will need to be planted from the top of the bank to the water surface to achieve 6 foot spacing. 0.611bs of both temporary and permanent seed will achieve a seeding rate of 151bs/acre. 193 square yards of coconut coir matting will be required to cover the bank. See the attached erosion and sedimentation control plan for the species list. Site 2: Both the right bank and the left bank should be sloped back (cut) from the water surface using a 2:1 slope from the pipe downstream approximately 40 feet (0.01 ac). The sloping should end where the channel narrows to a more typical bankfull width. A rock toe should be added on both the left and right bank toe of slope from the pipe downstream approximately 25 feet. Rock sizes for the toe of slope should be a minimum of 4x3x2. Where the mid- channel bar occurs, approximately 25 feet downstream of the pipe, the apex of the cross vane should be placed and tied into the existing banks. The invert of the cross vane should be the same height as the invert of the pipe in order to control grade and raise the bed elevation. The area where sloping of the banks occurs should also be seeded and planted for stabilization. A total of 15 live stakes will need to be planted from the top of the bank to the water surface to achieve 6 foot spacing. 0.9lbs of both temporary and permanent seed will achieve a seeding rate of 151bs/acre. 214 square yards of coconut coir matting will be required to cover the bank. See the attached erosion and sedimentation control plan for the species list. Site 3: The right bank from the edge of the rock wall should be sloped at 2.5-3:l ratio for a distance of as indicated in the design details. The left bank should be sloped (cut) at a 2.5-3:1 ratio from the first bend in the creek and tied into the existing bankfull bench which is located approximately 30 feet downstream (0.006 acres). The existing bankfull bench is approximately 35 feet long. Downstream of the bench, the left bank has also eroded and is lacking adequate vegetation to the existing culvert. From the existing bankfull bench to the culvert the left bank should be sloped (cut) to a 2.5-3:1 slope for approximately 60 feet (0.01 acres). The area where sloping of the banks occurs should also be seeded and planted for stabilization. A total of 27 live stakes will need to be planted from the top of the bank to the water surface to achieve 6 foot spacing. 1.3lbs of both temporary and permanent seed will achieve a seeding rate of 15lbs/acre. 386 square yards of coconut coir matting will be required to cover the bank.

Latitude 35.9823180 Longitude -81.9390580 Waterbody: Linville River X Debris removal Channel realignment X Seeding X Bank sloping X In-stream structures Adjust channel dimension X Bank stabilization X Riparian planting There are several issues that need to be addresses at this site, the foremost being a blowout of the Lineville River at a meander bend (Site 1). This blowout created a new bypass channel on prime farmland. Woody debris has also been deposited on the right bank downstream from the blowout (Site 2). Further downstream on the left bank a 50 foot section of riprap has eroded leaving a bare and unstable bank (Site 3). Across from the rip rap associated with Site 3 on the right bank, several trees have fallen into the channel and onto the floodplain (Site 4). According to the Economic Evaluation the project will protect 8 acres of prime farmland valued at 70,000, 500,000 Christmas tree plants valued at $125,000, and a bridge valued at 27,000. According to the Damage Survey Report the installation cost of emergency work would be $79,300. The recommendations for improvements listed below would cost approximately $30,040.00. for Improvements: Site 1: The work that will be done to stabilize the Linville River at this site will involve reestablishing the banks and channel. The landowner has applied to another agency for the material and work that will be required to fill in the bypass channel and reestablish that land that was once his Christmas Tree farm. Two plugs, one at the upstream end of the site and one at the downstream end of the site, will be installed to prevent water from entering the blow out channel. The plugs will each be 25 feet wide. The plugs will require approximately 333 cubic yards of fill. Gravel fill from the blowout channel will be used to reinforce the toe of the upstream plug. Logs from the debris removal site will be used to reinforce the toe of the downstream plug. Two J-Hooks will be installed as indicated by the design aerial and tied into the right bank as indicated by photo 3. Each J-Hook will induce a 18 foot sill. The plugs will be seeded, matted, and planted. Site 2: Downstream from Site 1, on the right bank, woody debris will be removed. Site 3: Downstream from Site 2, on the left bank, the rip rap will be moved to cover the toe of the slope. The bank will then be shaped, seeded, matted, and planted. For approximately 50 feet. Site 4: Across from Site 3, a large tree that has fallen in the channel will be removed. These trees will be used to protect the toe of the downstream plug. Planting: A total of 110 feet will be seeded, matted, and planted. The banks on the plugs are approximately 6 feet high and the bank on the rip rap reach is approximately 4 feet high. At each planting site, the water surface to the top of the bank should be planted with live staking (0.03 acres). 35 live stakes should be planted to achieve 6 foot spacing. A 25 foot riparian buffer should be planted on the plugs (0.03 acres). To achieve a planting rate of 680stems/acre, 23 stems will be needed on this riparian zone. The entire 0.08 acres should be seeded using both temporary and permanent seeding mixes. 1.1lbs of each type of seed will be needed to achieve an application rate of 15Ibs/acre, 662 square yards of coconut coir matting will be required to cover the banks. A species list for planting and permanent seeding is enclosed in the attached erosion and sedimentation control clan. BUCK 17 N Ci I N E 1: R I N (. PAGE OF CLIENT AVERY r-k11?

There arealso two sites where woody debris is either in the channel or on the adjacent floodplain. According to the Economic Evaluation the project will protect two homes valued at $80,000, a driveway valued at $5,000, and a state road and state bridge which were given no values. According to the Damage Survey Report the installation cost of emergency work would be $3,100. The recommendations for improvements listed below would cost approximately $5,930. for Equipment access to this site is from Claude Pyatte Rd. Woody debris should be removed in two areas as indicated by the design aerial. Both the right and left bank should be sloped for approximately 150 feet each at a 2:1 angle also as indicated by the design aerial (0.08 ac). This work can be done with a CAT 315. The logs in the channel may be used for toe protection. Both banks should be seeded, matted, and planted for stabilization over a length of approximately 150 feet The water surface to the top of the bank (approximately 4 feet in height) should be planted with live staking (0.06 acres). 37 live stakes should be planted on the inside of the meander bend (right bank) and 149 should be planted on the outside of the meander bend (left bank). A riparian buffer on the right bank cannot be planted because of the proximity of Stamey Branch Road. On the left bank it is recommended that a 25 foot riparian buffer be planted using bare root trees (0.09 acres). To achieve a planting rate of 680stems/acre, 62 stems will be needed for this 0.09 acre riparian zone. The entire 0.15 acres should be seeded using both temporary and permanent seeding mixes. 2.21bs of each type of seed will be needed to achieve an application rate of 15lbs/acre. 119 square yards of coconut coir matting will be required to cover the banks. A species list for planting and permanent seeding is enclosed in the attached erosion and sedimentation control plan.

(Group 12) SB-1 Avery County EWP Photographs --- Page 2 of 2 5,17!05 Erosion and Sediment Control Plan Emergency Watershed Protection Program Avery County The following erosion and sediment control measures will be incorporated into all stream repair sites. 1. 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 31bs per 1,000 sq ft or 1301bs per acre Temporary Seeding (April to August): Foxtail Millet 1 lb per 1,000 sq ft or 40 lbs 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 1/2 the full lbs/acre rate. Permanent Seeding Permanent seeding will be accomplished using the mix listed below: Buck Engineering 2 of 8 River Works 3 Riparian Seed List Scientific name Agrostis alba Carex vulpinoidea Elymus virginicus Juncus effusus Panicum clandestinum Polygonum pennsylvanicum Bidens frondosa Coreopsis lanceolata 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% Beggars Ticks 5% Lance leafed Coreopsis 15% Partridge Pea 5% Wingstem 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 amomum Silky Dogwood Hamamelis virginiana Witch-hazel Carpinus caroliniana Ironwood Corylus americana Hazel-nut Alnus serrulata Tag Alder Ostrya virginiana Hornbeam Spirea tomentosa Hardhack 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 -11 Large Trees Scientific name Common name Aesculus octandra Buckeye Tsuga canadensis Canadian Hemlock Platanus occidentalis Sycamore Acer rubrum Red Maple Quercus alba White Oak Quercus rubra Red Oak Liriodendron tulipifera Tulip Poplar Tsuga caroliniana 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 i 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 EWP 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 6261b/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.

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 reviewed and discussions were held with knowledgeable field office and 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.
