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. Stream stabilization will onlv be conducted in areas exhibitinz active erosion. Due to the vallev constraints, landowner stipulations, and existing channel morphology at the project site, stream channel relocation is not feasible. Construction access roads are proposed in predetermined areas to minimize the impact effects o heavy equipment on the channel and existing riparian zones. Construction will be conducted durinz low flow events. Any rises or increases in flows will require that equipment exit the channel. Streambanks disturbed via stabilization activities will be seeded and covered immediately. 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 Page 9 of 12 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 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 http://h2o.enr.state.nc.Lis/ncwetlands/strmg.i.de.h.tmi. 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. Not annlicable 2. Mitigation may also be made by payment into the North Carolina Wetlands Restoration Program (NCWRP).

Photos - July/August 2003 1.0 INTRODUCTION This stabilization plan addresses channel improvements to be implemented by the Natural Resources Conservation Service (MRCS) along Raccoon Creek. The project includes a 2,700 linear-foot section of stream along the John Queen Farm, immediately east of Waynesville in Haywood County (Figure 1). Mulkey Engineers and Consultants (MULKEY) was retained by the NRCS to design and oversee the implementation of stabilization techniques using natural channel design methodologies. Implementation is planned for the winter of 2003/2004. :, 7 -? E Raccoon Creek is situated within the French Broad River Basin in western North Carolina. It is part of Subbasin 04- 03-05, including the Pigeon River, East and West Fork Pigeon Rivers, Richland, Jonathans, Crabtree, and Cataloochee Creeks. Raccoon Creek originates approximately two miles southeast of Waynesville near Wolfpen Mountain. It flows in a northerly direction along the eastern edge of Waynesville through the John Queen Farm and ultimately into Richland Creek at bake Junaluska. According to the North Carolina Division of Water Quality (NCDWQ, 2002), water quality in this subbasin has shown improvement over the past several years. The headwaters of Raccoon Creek continue to experience problems with non-point source pollution, mostly from agriculture. Based on map reviews, the stream has also been channelized in several areas. Very little riparian buffer is present throughout the lower portion of the creek. The overall Raccoon Creek channel has no riparian buffer and exhibits signs of channelization through a major portion of the John Queen project site. 2.0 OBJECTIVE The objective of this project is to reduce erosion and sedimentation originating through this reach and improve the overall habitat values, both aquatic and terrestrial. This objective will be met by establishing rock structures (referred to as vanes) within noted problem areas to divert the shear stresses away from the eroding streambanks. This project is classified as stabilization rather than restoration due to several reasons: landowner constraints; overall project costs; and existing land uses. Natural channel design methodologies are preferred over traditional engineering approaches for this type of stabilization. These methodologies will be implemented throughout the stabilization process to ensure the channel dimension, pattern, and profile remain consistent and the reach does not aggrade or degrade. 3.0 EXISTING CONDITIONS Overall, this 2,700 linear-foot reach of Raccoon Creek appears moderately unstable. The stream lacks overall sinuosity, which denotes prior channelization. A small levee existing along the left streambank (facing downstream) at the beginning of the project also reveals evidence of previous dredging. Vertical, eroding banks exist along major portions of the stream, especially around the outsides of the confined meander bends. Active scouring was evident throughout most of these areas. Bankfull indicators were difficult to recognize in most cases, further denoting the overall instability of the channel. No riparian buffer exists along the project. 3.1 Current Stream Classification Raccoon Creek, from it source to Richland Creek, is designated as Class B waters. Class B waters are suitable for primary recreation and other uses consistent with Class C standards. Primary recreational activities include swimming, skin diving, water skiing, and similar uses involving body contact with water where such activities take place in an organized manner or on a frequent basis. There are no restrictions on watershed development or types of discharges. The designation was given in April 1958 (NCDWQ, 2003). Existing site conditions demonstrate that the watershed, including this reach of Raccoon Creek, has undergone significant changes through the past decades. These changes include the introduction of livestock and the removal of riparian vegetation. Therefore, this classification is not an accurate reflection of the current conditions of the stream. Class C waters are protected for secondary recreation, fishing, wildlife, fish and aquatic life propagation and survival. These uses include wading, boating, and other aspects involving human contact in an infrequent, unorganized, or incidental manner. Richland Creek, downstream of Raccoon Creek, is designated as Class B waters upstream of Lake Junaluska and Class C waters from the dam to the Pigeon River. These classifications were issued in 1958 and 1974, respectively. 3.2 Available Discharge Data Discharge data for the West Fork Pigeon River was obtained from the United States Geological Survey (USGS) Stream Gage approximately eight miles south of the project. No Stream Gage data was available for Raccoon Creek. Daily discharges from October 2001 to September 2003 are shown in the chart below. These discharges represent an increase in rainfall and surface runoff for the period beginning October 2002 through the present time. Evidence of additional bank destabilization along Raccoon Creek has confirmed this analysis. c 2000 y 1000 a m a? cs a ? 100 a: ao m L V Vi O y- 10 J H x 0 USGS 03455500 N F PIGEON R ABOVE LAKE LOGAN HR HAZELWOOD, HE Oct Jan Apr Jul Oct Jan Apr Jul 2001 2002 2002 2002 2002 2003 2003 2003 DATES: 09/03/2001 to 09/03/2003 23:59 EXPLANATION - DAILY MEAN DISCHARGE - MEDIAN DAILY STREAHFLOW BASED ON 48 YEARS OF RECORD X MEASURED Discharge 3.3 Existing Condition of Raccoon Creek Longitudinal profile and cross section surveys were conducted along the reach during July and August 2003. These surveys were confined to the main channel since work outside of the existing streambanks was not part of the project. Longitudinal surveys were taken at the head of each feature (riffle, run, pool, and glide) and at the maximum pool depths. A total of five detailed cross sections were taken at predetermined locations along the reach (Figure 2). These cross sections were taken near areas where bank stabilization measures were anticipated. Reference reach data is provided for comparison purposes only. This reference reach survey was completed by the NRCS and covers a section of Raccoon Creek upstream of the project area. Based on the surveys, Raccoon Creek is characteristic of a manipulated "E4" stream type. According to the morphological description presented in Applied Fluvial Geomorphology (Rosgen, 1996), E4 stream types are channel systems with low to moderate sinuosity, gentle to moderately steep channel gradients, very low width/depth ratios, gravel-dominated channels with well developed floodplains. The E4 stream types are hydraulically efficient channel forms which maintain a high sediment transport capacity. The narrow and relatively deep channels maintain a high resistance to plan form adjustment which results in channel stability without significant down-cutting. These channels are very stable unless the streambanks have been disturbed, such as the John Queen Site. As a result, changes in sediment supply and streamflow have occurred. This channel type is susceptible to accelerated bank erosion due to the absence of riparian vegetation. Specific information pertaining to the channel is presented in the abbreviated morphological table at the end of this section. Surveys of the longitudinal profile and cross sections are shown in Appendix A. A pavement/sub-pavement sample was taken near Station 22+00 to compare with pebble counts conducted at each cross section. Based on the information collected, MULKEY was able to calculate shear stress, velocities, and entrainment (point of incipient motion). The results of the pebble counts and pavement/sub-pavement sample are presented in the chart at the end of this section. Cross Section No. 2 was used in the calculations for shear stress, entrainment, and velocity. This section was chosen based on its relation to the overall assessment of the reach. The entrainment of Raccoon Creek through this segment substantiated that the reach is unstable. The required shear stress appears adequate to move the large particles; however, the duration required to keep the particles moving downstream are not present due to the flashy flows of the water course. Bankfull velocities were calculated using five different methodologies at the cross section. Velocities averaged 6.73 feet per second (fps). Bankfull discharge was estimated at 196.5 cubic feet per second (cfs). Detailed information regarding each of the calculations is presented in Appendix B.

Pfankuch (1975) developed a system to rate channel stability which has been widely used by stream restoration professionals. This system is used to quantitatively describe the potential for sediment material detachment and changes in sediment supply due to changes in streamflow and/or changes in watershed condition. It has also been used to generally assess fisheries habitat conditions, and to indirectly assess streambank damage resulting from cattle grazing. Since this method was developed prior to the stream classification system, the good, fair, and poor rating values have been adjusted by stream type (Rosgen, 1996). The overall rating for this reach was 100, which falls within the "poor" category. Streambank erosion rates were calculated using the BEHI method as described and taught by Dave Rosgen, Wildland Hydrology, Inc. Bank erosion occurs as a result of a number of processes, including dry ravel, mass wasting, surface erosion, hquification, freeze-thaw, fluvial entrainment, and ice scour. The ability of streambanks to resist erosion is primarily determined by the following factors: ? the ratio of streambank height to bankfull stage; ?? 91y` ii Aata f 1+?t ' .1.481 , ?1 / B.•. a ?: ,'t,c t 'wit T?5 ?,T , ,?' `4 . r,k1?t Y rh .?``; Sl it i SQL II4:T - ? the ratio of riparian vegetation rooting depth to streambank height; ? the degree of rooting density; ? the composition of streambank materials; ? streambank angle (i.e., slope); ? bank material stratigraphy and presence of soil lenses; and ? bank surface protection afforded by debris and vegetation. The vertical streambank at Station 7+00 was measured to determine an approximate erosion rate per year. This vertical streambank provides an overall representation of the streambanks through the project area. It was considered based on its anticipated sediment contribution during high-flow events. The BEHI rating was 47.7, indicative of extreme bank erosion potential. Based on this number, erosion rates could reach approximately 7 feet' per year. This measurement was taken along the outside of a meander bend throughout an unstable area. Overall, Raccoon Creek should exhibit a BEHI rating of very high, with erosion rates averaging approximately 1 foot' per year per linear foot, or approximately 125 tons of sediment per year. 3.5 Reference Reach Comparison Since this project is considered stabilization rather than restoration, reference reach data is not generally required for design and implementation. However, MULKEY was able to obtain reference reach data from the NRCS covering a short segment of Raccoon Creek upstream of the project area. This data was used as a comparison between bankfull cross- sectional area, width, depth, and discharge of Raccoon Creek and the North Carolina Rural Mountain Regional Curves (NCSU SRI, 2003). Based on field surveys and bankfull verifications, the data associated with bankfull cross-sectional area and bankfull width were significantly below the 95% confidence intervals of the calculations. MULKEY compared the findings with those associated with the existing reference reach data and noted the same discrepancies. Ratios were calculated noting the differences with the reference reach data and the regional curves. Based on these ratios, which were 0.53 for bankfull cross-sectional area and 0.54 for bankfull width, the field determined cross-sectional areas and bankfull widths at the five cross sections distinctly compare with the existing reference reach data. Therefore, the determined locations of bankfull are justified, although they do not agree with the regional curve data. 4.0 DESIGN RECOMMENDATIONS Based on the existing condition surveys and interpretation of the data, this reach of Raccoon Creek is unstable. Aggradation processes are associated with the following channel adjustments: increase in width/depth ratio; increase in sediment storage; increase in bank erosion rates; decrease in pool quality and other fishery habitat features; increase in the loss of riparian land and associated sediment availability from bank erosion and lateral migration; and increase in over-bank flooding. Most of these processes were observed along the 2,700 linear-foot reach. Photos are presented in Appendix C. MULKEY offers the following recommendations for stabilizing this reach of Raccoon Creek: 1. Construct cross vanes in pre-determined locations along the 2,700 linear-foot reach to help maintain and possibly decrease the width/depth ratio. These structures will be placed only in riffle sections and will provide bank stability, grade control, and habitat for aquatic organisms. 2. Construct rock vanes along the outside of meander bends requiring stabilization. These vanes will help redirect flows away from the outside banks, provide limited bank stabilization, and enhance habitat for aquatic organisms. 3. Reduce existing levee heights and re-shape the stream banks. This recommendation is feasible only in a limited number of locations. The levee along the western side of the channel is approximately 150 feet in length. The vertical banks along both sides of the channel will be reshaped from the bankfull elevation upward. This material will act as additional fill required in areas associated with the installation of the cross vanes. 4. Access roads will be placed along the western bank of the stream to allow construction equipment and personnel to enter the reach with minimal disturbance. The locations of these roads will be determined at the onset of construction to minimize overall impacts to existing riparian areas. These roads will be re-graded and planted upon completion of the in-stream work. 5. Enhance riparian buffers in areas where little to no buffers currently exist. These buffers will be planted with native tree species. Erosion and sediment control issues exist along this project. Special precautions will be taken during construction to minimize unnecessary sedimentation into the stream. Sediment control fencing may be established along the affected edges of the pasture. This fencing will direct any loose sediments resulting from sheet flow into a storage area away from the stream. Any areas excavated or voided of vegetation will be seeded and matted upon exit from the area. Since in-stream work is required for this stabilization, all equipment will be inspected for fluid leakage on a daily basis. Work will not be conducted during rain events or when water levels are above average. All equipment will be stored outside of the stream and its associated riparian area when not in use. The construction supervisor will oversee all activities relating to in-stream work. 5.0 DESIGN IMPLEMENTATION Implementation will follow the design sequence listed on the plan sheets. The installation of structures will proceed from upstream to downstream. As a result, shifts or changes in the flows can be addressed with the placement of structures downstream. The actual locations of the structures may be adjusted, depending on site conditions. Implementation will follow the proposed sequence listed below. 1. Staging areas for equipment and materials and access roads will be identified and located in the existing pastures. 2. Access Point #1 from Sunnyside Road (SR 1809) will be constructed for upstream work between Stations 0+00 and 15+00. A temporary culvert will be installed in the roadside ditch to allow access for equipment and the staging of materials. Contractor will place geotextile material and gravel for the roadways leading to and from the construction areas. The fences adjacent to the creek on the John Queen Property will be removed. 3. Access Point #2 from Ratcliffe Cove Road (SR 1818) will be constructed downstream work between Stations 15+00 and 28+53. Contractor will place geotextile material and gravel for the roadway leading to and from the construction areas. The remaining fences adjacent to the creek on the John Queen Property will be removed. 4. Contractor will begin stockpiling materials. 5. Approximate structure locations will be field located. 6. Structure Nos. 1 through 10 will be constructed and the banks associated with the Queen property will be graded to the bankfull elevation, where necessary.

Impacts to the existing vegetation will be minimized to the extent practicable. Excess soil will be taken to Station No. 21+10 and the wet area in the pasture. 13. NRCS and Haywood County Soil and Water Conservation District personnel will review the structures and associated earthwork between Station Nos. 0+00 and 15+00. 14. Access Point #1 will be seeded, covered with erosion control material, and planted with native vegetation. The temporary culvert will be removed upon exit from this area. All geotextile material and gravel associated with roadway access to the construction areas will be removed. 15. Structure Nos. 24 through 32 will be constructed and the adjacent stream banks will be graded to the bankfull elevation, where necessary. Impacts to the existing vegetation will be minimized to the extent practicable. Excess soil will be taken to Station No. 21+10 and the wet area in the pasture and Station No. 28+53. 16. The old channel at Station No. 21+10 will be filled and Structure No. 33 will be installed. 17. Farm drains and two swales will be constructed to provide additional drainage for the wet area in the pasture near Station No. 22+00. 18. Structure Nos. 34 through 44 will be constructed and the adjacent stream banks will be graded to the bankfull elevation, where necessary. Impacts to the existing vegetation will be minimized to the extent practicable. Excess soil will be taken to Station No. 28+53 and stockpiled in a suitable location for the landowner's use. Existing debris, rip rap, and rubble will be removed from the existing channel and either buried on site or taken to a proper disposal facility. 19. The radius at Station 28+50 will be increased and Structure Nos. 45 and 46 will be installed. A bankfull bench will be constructed throughout the area associated with the old channel. The bench will be graded at a slope determined by the on-site construction engineer and connected with existing ground. 20.
