general land use in the vicinity of the project at the time of this application The Boone Fork enhancement site is located on the U S National Forest The land is managed for timber and recreational purposes There is a forest service campground adjacent to the lower portion of the site Relic impacts from historic agricultural and logging practices have impacted Boone Fork Deep Cove Creek and an unnamed tributary (UT) to Boone Fork Thirteen sites on Boone Fork totaling 528 If have been identified with eroding stream banks and degraded aquatic habitat The U S Forest Service determined the culvert on Deep Cove Creek in the Boone Fork campground is impeding fish passage Four relic log culverts and 150 If of eroding stream banks on an intermittent UT to Boone Fork are causing excess sedimentation in the Boone Fork Pond Public Fishing Area In addition bank scour has occurred behind Boone Fork Pond outfall pipe See attached Boone Fork stream rehabilitation and habitat enhancement plan for more details 3b List the total estimated acreage of all existing wetlands on the property No wetlands were identified within the Boone Fork Stream rehabilitation and habitat enhancement site 3c List the total estimated linear feet of all existing streams (intermittent and perennial) on the property Approximately 898 If of prennial and intermittent streams are being proposed for enhancement at the Boone Fork stream enhancement site Total linear feet of stream on the U S Nation Forest property is unknown 3d Explain the purpose of the proposed project The purpose of the project is to remiediate the historic impacts by stabilizing stream banks improving aquatic habitat and fish passage 3e Describe the overall project in detail including the type of equipment to be used All proposed enhancements are described in further detail in the attached Boone Fork stream rehabilitation and habitat enhancement plan The stream channel s design dimensions are based on the mountain and piedmont regional hydraulic geometry curve data for riffles and onsite conditions Eroding stream banks and habitat will be enhanced on the thirteen sites totaling 528 If of stream on Boone Fork Stream banks will be reshaped a bankfull bench will be created and in stream structures (J hook cross vanes wood toe root wads etc ) installed in order to stabilize the stream banks and improve aquatic habitat To improve fish passage through the culvert on Deep Cove Creek we propose to decrease the water velocity through the culvert by raising the water elevation within the culvert A rock cross vane will be installed to raise the head of the riffle downstream of the culvert by approximately one foot The elevation of the stream channel will be stepped down to the existing stream channel elevation through two additional cross vanes The stream channel will be reshaped based on the regional hydraulic geometry curve values and onsite conditions Eroding stream banks on the UT to Boone Fork will be stabilized and aquatic habitat enhanced by removing the 4 existing culverts and reshaping 150 If of stream banks The bank behind Boone Fork Pond s outfall pipe will be stabilized by installing non woven filter fabric with a layer of rip rap on top Disturbed stream banks will be reshaped to 1 2 to 1 3 slopes and stabilized with coir fiber matting The clearing of riparian vegetation will be minimized and primarily limited to eroding stream banks Salvaged woody vegetation and sod mats will be used to re vegetate the disturbed stream banks wherever possible These areas also will be seeded with a temporary and permanent native riparian seed mix and mulched with straw Two hundred and fifty live stakes and 200 one gallon containerized trees and shrubs will be planted on disturbed stream banks Trees and shrubs will be planted in higher densities along the outside of meander bends and at structures During construction heavy equipment (track hoe) will only access the stream when absolutely necessary For this project it is anticipated that most of the track hoe work can be accomplished from the top of the bank All construction materials including rock root wads logs and erosion control materials will be stockpiled at a central location at the site To limit disturbance of soils all equipment will travel along existing USFS roads and identified travel corridors Disturbance of soils will be limited to only what work can be accomplished and stabilized on a daily basis As a structure is completed the site will be sloped stabilized with sod mats or re seeded Any stockpiled soils or disturbed areas on steep slopes will have erosion control fencing installed as needed Page 4 of 12 PCN Form — Version 1 3 December 10 2008 Version 4 Jurisdictional Determinations

County North Carolina S Mulberry Creek Decision Notice & Finding of No Significant Impact Mulberry Project USDA Forest Service Grandfather Ranger District Pisgah National Forest Caldwell County North Carolina Decision and Rationale Decision Based upon my review of the alternatives I have decided to select a modified Alternative C (Selected Alternative) of the Mulberry Project Environmental Assessment (September EA - see Section 12 Chapter 1) on the Grandfather Ranger District Pisgah National Forest and the Project Design Features listed in Section 2 4 Appendix A and Appendix F of the EA The Selected Alternative is within the Lower Mulberry Forest Plan Analysis Area (AA) and specifically within Compartments 2 5 7 16 21 and 23 (project area) The modification is to Stand 6 and is a 1 acre exclusion to meet Forest Plan standards The Selected Alternative will Harvest about 274 acres using the two age regeneration harvest prescription (average minimum of 15 30 ft2 basal area retained per acre) The ten harvest units range in size from about five acres to 40 acres with the average size about 28 acres Perform road maintenance on the existing roads that access the area Utilize and reconstruct about 18 miles of existing old woods roads (unauthorized roads) and develop about 2 0 miles of new temporary roads to access harvest stands Following harvest activities the 18 rules of old woods roads will be placed on the Forest s transportation system as authorized (system) roads stabilized (i a shaped waterbarred and seeded) and accessed for motorized administrative use only —they will be available for future access needs The new temporary roads will be disked seeded and permanently closed (about 15 acres of temporary roads will serve as permanent wildlife linear openings) 0 Selectively apply herbicides to control /manage non native invasive plant species along roads 0 Selectively apply herbicides and use hand tools to ensure successful regeneration of a variety of native tree species in harvested areas especially oaks by controlling competing vegetation 0 Designate at least 50 acres of small patch old growth communities within Compartments 3 18 20 and 21 (224 total acres designated) 0 Apply erosion control measures to protect water quality These measures will be for all activities including roads and log landings 0 Perform stream rehabilitation on 1/2 mile of Boone Fork Branch along the drainage above and below the Boone Fork Reservoir and at the crossing on Deep Cove and Forest Service Road 2055 Rehabilitation on Boone Fork Branch will include placing about 16 rock and log vanes Rehabilitation above and below the reservoir includes sloping back stream banks planting trees/ shrubs along stream banks and placing rock below the culvert below the reservoir Rehabilitation at the crossing on Deep Cove includes modifying the crossing to allow fish passage (a more detailed description is located in the project record) Daylight along either side of a portion of Forest Service Road (FSR) 189 (Spencer Branch Road) to allow more sunlight to reach the roadbed by harvesting trees within fifteen feet either side of the road (so the road would dry out more quickly thus reducing rutting) The entire six mile length of the road will not be daylighted - only those Decision Notice & Appendix H 2 Mulberry Creek Project portions where sunlight does not adequately reach the roadbed 0 Develop a 2 acre wildlife field from a log landmg in Unit 11 to native grasses and forbs to enhance wildlife food sources Plant an old variety apple trees in log landings after harvest is completed to enhance wildlife food sources in the area There may be opportunities to plant advanced oak seedlings in Units 5 9 and 12 MonitorinQ The following monitoring will be implemented for the Selected Alternative 1) National objectives include reducing impacts from invasive species and improving the effectiveness of treating selected invasive species on the Nation s forests and grasslands Survey areas would be established to monitor control efforts Survey areas would be established before control treatment checked during treatment and within nine months after treatment A post treatment evaluation report would be completed and filed in the project file (Purpose is to monitor effectiveness of treatments) My decision is based on a review of the project record that shows a thorough review of relevant scientific information a consideration of responsible opposing views and the acknowledgment of mcomplete or unavailable information scientific uncertainty and risk Rationale The Forest Plan Amendment 5 (1994) designated the Mulberry Project AA as Management Areas (MA) 2A 3B and 18 MA 2A places an emphasis on [v]isually pleasing scenery for forest visitors Roads are generally open with the adjacent forest land managed to provide that pleasing visual experience Timber production is permitted but modified to meet visual quality objectives (Forest Plan page III 63) MA 3B places an emphasis on [a] sustainable supply of timber with few open roads while permitting road construction for resource management and to manage habitat of mixed ages of forests primarily for wildlife species such as wild turkey deer and other animals requiring similar environments (Forest Plan page Ill 71) Embedded within MAs 2B and 3B is MA 18 which [c]onsists of the aquatic ecosystem riparian ecosystem and closely associated plant and animal communities and is actively managed to protect and enhance where possible the distinctive resource values and characteristics dependent on or associated with these systems (Forest Plan page III 179) The purpose and need for the proposal is listed below (see also Section 13 Chapter 1) There is a need to develop between 4 / 14 / early successional (0 10 year age class) wildlife habitat in the project area because there is currently one percent 0 10 year wildlife habitat The purpose of the two age harvesting is to develop additional early successional wildlife habitat in the project area and increase the amount of hard mast producing tree species (oaks and hickories) The Mulberry area is the next area the Grandfather Ranger District has identified to ensure each compartment is scheduled for management analysis at a 10 year interval There is a need to control /manage populations of invasive exotic plants such as princess tree tree of heaven Japanese plume grass and others because they have been found in the project area The purpose of the herbicide treatment of mvasive /exotic plants is to reduce potential for spread of them in the project area There is a need to improve water quality and fish habitat along and within stream reaches because sedimentation and erosion have been found in the project area and a culvert restricts fish passage The purpose of rehabilitating stream channels and providing fish passage is to improve water quality stream bank stability and fish habitat There is a need to designate small patch old growth communities in Compartments 3 18 20 and 21 because no small patch old growth communities are currently designated in them The purpose of designating small patch communities in Compartments 3 18 20 and 21 prior to harvesting is to ensure there is a network of old growth communities across the Forest There is a need to develop about three acres of permanent grass /forb wildlife habitat in the project area because there is currently 24 acres of permanent grass /forb wildlife habitat The purpose of the about two acre Decision Notice & Appendix H 3 Mulberry Creek Project wildlife field and 15 acre linear opening is to develop about 27 acres of permanent grass /forb wildlife habitat in the project area further moving the project area towards the desired condition of 43 acres I believe the Selected Alternative achieves the project s Purpose and Need as well as Forest Plan direction and standards and will move the resources in the project area towards the Forest Plan s desired future condition The project analysis also considered public concerns (see also Appendix H Response to Comments Received During the Mulbemj Project 30 day Notice & Comment Period) In reaching my decision I carefully weighed the effects analyses of the alternatives analyzed in detail the public comments I received on the proposal and the Agency s response to comments The Mulberry Project Interdisciplinary Team (IDT) conducted field surveys database queries and other localized analysis in order to determine effects the alternatives analyzed in detail could have on the area s ecology including threatened endangered and sensitive species During their analyses the IDT took a hard look at past present and reasonably foreseeable future actions that could be combined with expected effects from the Mulberry proposal I believe they provided me sufficient analyses and conclusions to make a reasoned decision The Selected Alternative will harvest about three percent of the 8 653 acre Lower Mulberry AA My decision is based on a review of relevant scientific information as contained in the project record I believe the effects analyses support my decision and are based on the best available science Other Alternatives In addition to the Selected Alternative I considered one other alternative in detail Alternative A - No Action A comparison of these alternatives can be found in Section 2 5 Chapter 2 Alternative A - No Action Under Alternative A current management plans such as existing wildlife management wildfire suppression general road maintenance and recreation would continue to guide management of the project area (see Section 2 21 Chapter 2) I did not select this alternative for several reasons This alternative would not have developed early successional habitat conditions for wildlife species used herbicides to control /manage non native invasive plants designated small patch old growth performed stream restoration activities in Boone Fork Branch daylighted along Forest Service Road 189 nor developed a wildlife field and linear wildlife habitat I believe active management at this time and in this location is important to achieving Forest Plan objectives Alternatives Not Considered Section 2 3 of the EA disclosed three alternatives I considered but eliminated from detailed study along with rationale for why they were not considered Since they were not considered in detail in the EA they were not considered in the range of alternatives for my decision Public Involvement The proposal was listed in the National Forests in North Carolina s April and July 2007 Schedule of Proposed Actions The proposal was provided to over 120 members of the public and other agencies for comment during scoping that was initiated on May 15 2007 In addition as part of the public involvement process the agency hosted an open house meeting in Collettesville North Carolina on July 10 2007 A post card was mailed to over 120 members of the public informing them of the open house meeting a press release explaining the open house meeting was provided to local newspapers and notices were placed in numerous businesses public areas and local residents in the surrounding area Twenty members of the public provided comments on the proposal during scopmg and at the July 10 2007 open house A 30 day Notice and Comment period pursuant to 36 Code of Federal Regulation (CFR) 215 5(b)(2)(i) was initiated when a legal notice was placed in the August 16 2007 edition of The McDowell News The scopmg package and August 2007 Preliminary Analysis were placed on the Forest s website The September 2007 EA is available upon request and is also on the Forest s website Decision Notice & Appendix H 4 Mulberry Creek Project Finding of No Significant Impact After considering the environmental effects described in the PA I have determined that these actions will not have a significant effect on the quality of the human environment considering the context and intensity of impacts (40 CFR 1508 27) Thus an environmental impact statement will not be prepared I base my finding on the following 1 Impacts that may be both beneficial and adverse A significant effect may exist even if the Federal agency believes that on balance the effect will be beneficial My finding of no significant environmental effects is not biased by the beneficial effects of the action (Section 12 Chapter 1) 2 The degree to which the proposed action affects public health or safely/ There will be no significant effects on public health and safety and implementation will be in accordance with project design features and for herbicide use will adhere to Material Safety Data Sheets and Product Labels (Section 2 4 Chapter 2 Section 3 4 Chapter 3 and Appendix F) 3 Unique characteristics of the geographic area such as proximity to historic or cultural resources park lands prime farmlands wetlands wild and scenic rivers or ecologically critical areas There will be no significant effects on unique characteristics of the area because there are no park lands prune farmlands wetlands wild and scenic rivers or ecologically critical areas in the project area nor are there local law or requirements unposed for the protection of the environment (Section 312 Chapter 3) 4 The degree to which the effects on the quality of the human environment are likely to be highly controversial Controversy with this element is related to scientific controversy about effects of the project I believe the degree of effects on the quality of the human environment are not expected to be highly controversial because this project is similar in design and intensity to others that have taken place on the Grandfather Ranger District in the past and effects of those similar past actions are well known— there have been no unexpected impacts when anticipated and observed effects have been compared I believe my decision does not significantly affect old growth communities because no Forest Plan designated old growth communities or initial inventory old growth communities would be harvested 224 acres would be designated as small patch old growth communities and would not be scheduled for future harvest and 1083 acres ( >12 /) in the Mulberry Project AA averaging greater than 101 years are not scheduled for harvesting with the Selected Alternative I find the 224 acres of small patch old growth communities the Selected Alternative will designate in the Mulberry Project AA more than meets the Forest Plan s old growth strategy standards and would not significantly affect old growth attributes and associated wildlife Forest Plan standards are to designate at least 50 acres of small patch old growth communities in the four compartments - the Selected Alternative will designate 24 additional acres (Sections 31 2 321 333 342 352 362 374 38 39 310 2 3 11 2 and 312 2 Chapter 3) 5 The degree to which the possible effects on the human environment are highly uncertain or involve unique or unknown risks We have considerable experience with the types of activities to be implemented The effects analysis shows the effects are not uncertain and do not involve unique or unknown risk (Sections312 321 333 342 352 362 374 38 39 3102 3112 and3122 Chapter 3) 6 The degree to which the action may establish a precedent for future actions with significant effects or represents a decision in principle about a future consideration The action is not likely to establish a precedent for future actions with significant effects because the project is site specific and effects are expected to remain localized and short term (Sections 312 321 333 342 352 362 374 38 39 3102 3112 and 312 2 Chapter 3) 7 Whether the action is related to other actions with individually insignificant but cumulatively significant impacts Significance exists if it is reasonable to anticipate a cumulatively significant impact on the environment Significance cannot be avoided by terming an action temporary or by breaking it down into small component parts Analyses disclosed for Decision Notice & Appendix H 5 Mulberry Creek Project each resource that cumulative impacts are not expected to be measurable long term or could combine with impacts of other past ongoing or reasonably foreseeable future actions in the AAs (Sections 31 2 5 3 21 334 342 352 362 375 38 39 3102 3112 and 312 2 Chapter 3) The degree to which the action may adversely affect districts sites highways structures or objects listed in or eligible for listing in the National Register of Historic Places or may cause loss or destruction of significant scientific cultural or historical resources The action will have no effect on districts sites highways structures or objects listed in or eligible for listing in the National Register of Historic Places (NHRP - Section 3 6 Chapter 3) The action will also not cause loss or destruction of significant scientific cultural or historical resources (Section 3 6 Chapter 3) A heritage report was completed for this project on August 28 2007 that identified 20 Class III archeological sites - no Class I or II archaeological sites were found Class III sites are not eligible to the NRHP and subsequently do not require protection from ground disturbing activities The North Carolina State Historic Preservation Office informed the project archaeologist on September 14 2007 that the proposal was cleared to proceed The degree to which the action may adversely affect an endangered or threatened species or its Habitat that has been determined to be critical under the Endangered Species Act of 1973 A Biological Evaluation (BE Appendix A) was completed for this project on July 23 2007 that concluded for threatened and endangered (T &E) species The proposed action will not affect (directly indirectly or cumulatively) any proposed or listed Federal T&E species The BE concluded for sensitive botanical species This proposal may impact individuals (Alternative C) of the S species Hexastylis contracta These impacts will not lead towards federal listing or loss of Forest viability The BE concluded for sensitive wildlife species There are no known direct impacts to populations of Diana fnhllanj as a result of the proposed action because the species is not known to occur in the wildlife AA There are both positive and negative indirect impacts to potential habitat as a result of the proposed action and past or foreseeable future activities because of loss of habitat The positive and negative indirect impacts to this species potential habitat are not considered significant because the proposed action is expected to benefit the Diana fritillary s potential habitat across the wildlife AA throughout the next ten years As a result the proposed action is not likely to cause a trend toward federal listing or loss of viability for this species across the wildlife AA and Forest The BE concluded for sensitive aquatic species No risk to population viability of any aquatic Sensitive species across the Forest would occur as a result of the implementation of the Mulberry Project The project would have no effect on Sensitive aquatic species or their habitat The US Fish and Wildlife Service (USFWS) concluded on September 17 2007 [w]e concur with your assessment that none of the proposed alternatives will affect federally listed endangered or threatened species or critical habitat Thus the requirements of section 7(c) of the Act are fulfilled (Section 3 9 Chapter 3 and Appendix A) 10 Whether the action threatens a violation of Federal State or local law or requirements imposed for the protection of the environment The action will not violate Federal State and local laws or requirements for the protection of the environment Applicable laws and regulations were considered in the EA The action is consistent with the Nantahala and Pisgah National Forests Land and Resource Management Plan Amendment 5 (Sections 1 1 1 12 and 13 Chapter 1) Findings Required by Other Laws and Regulations My decision to implement the Selected Alternative is consistent with the intent of the long term goals and objectives Iisted on pages III 1 and III 2 of Forest Plan Amendment 5 The project was designed to meet land and resource management plan standards and incorporates appropriate land and resource management plan guidelines (Sections 1 1 1 12 and 13 Chapter 1) Administrative Review

Decision Notice & Appendix H 8 BOONE FORK STREAM REHABILITATION AND HABITAT ENHANCEMENT PLAN ON BOONE FORK AND AN UNNAMED TRIBUTARY TO BOONE FORK CALDWELL COUNTY, NORTH CAROLINA Prepared in Partnership with the National Wild Turkey Federation and the United States Forest Service North Carolina Wildlife Resources Commission June 2012 Introduction The National Wild Turkey Federation (NWTF) has a Stewardship Agreement with the U S Forest Service (USFS) to provide logging upland and aquatic habitat improvements around the USFS Boone Fork campground Catawba River Basin Caldwell County North Carolina (Figures 1 and 2) Stream rehabilitation is needed in the Boone Fork watershed (Figure 2) because of excessive levels of stream bank erosion in sections of Boone Fork and an unnamed tributary and fish passage concerns at one culvert on Deep Cove Creek Aquatic habitat improvement will include enhancing degraded stream banks and aquatic habitat at 13 areas along a'' /z mile stretch of Boone Fork a North Carolina Wildlife Resources Commission (Commission) designated wild trout water improving fish passage at one culvert on Deep Cove Creek removing 4 culverts and stabilizing approximately 150 linear feet (If) of eroding stream bank on an unnamed tributary (UT) to Boone Fork above the Boone Fork Pond Public Fishing Area (PFA) and stabilizing the outfall pipe from the pond The entire project is located on Commission managed game lands The NWTF partnered with the Commission to provide stream enhancement design permitting and construction oversight Project Goals /Objectives The goals of the project are to rehabilitate the stream channel and improve aquatic habitat fish passage and riparian area on 778 if of stream around the USFS Boone Fork campground In order to meet these goals the project objectives include but are not limited to the following 1 Enhance degraded stream banks and aquatic habitat at 13 areas along a' /2 mile stretch of Boone Fork 2 Improve fish passage at one culvert on Deep Cove Creek 3 Removing 4 culverts and stabilize approximately 150 If of eroding stream bank on an UT to Boone Fork above the hatchery supported Boone Fork Pond PFA 4 Stabilizing the outfall pipe from the reservoir 5 Plant native trees shrubs and herbaceous ground cover on all disturbed stream banks and plant to provide long term bank stability stream shading and cover and food for wildlife Survey Methodology Representative riffle and pool cross sections were measured on Boone Fork at Site 10 and Site 6 and a longitudinal profile was surveyed on Deep Cove Creek (Figure 3) Survey data were taken using standard stream survey techniques described in Harrelson et al (1994) A laser level was used to survey the stream s cross section dimension and profile Bankfull was determined using field indicators that included a scour line along the bank channel benches and the existing floodplain The bankfull stage obtained from these measurements was evaluated using the North Carolina mountain and piedmont regional curve information (Harman et al 1999) Cross section data were used to classify the stream based on existing morphological features of the stream channel and valley type (Rosgen 1994 1996) Site conditions were analyzed and the project design developed using RIVERMorph stream assessment and restoration software Version 4 1 1 (RSARS 2007) Directions From 140 in Hickory travel north on US 321 to Lenoir turn left on Main Street (approximately 0 3 mile) turn right Valway Road (approx 1 3 miles) turn left at NC 90 and stay to it for 4 1 miles turn right on Mulberry Creek Road and stay on it for 4 7 miles turn right on Boone fork Road travel approximately l 9 miles to the Boone Fork PFA Existing Conditions The project is located in the Catawba River basin piedmont physiographic region Caldwell County (Hydrologic Unit Code 030501010503 NCDWQ sub basin 03083 1) The stream reaches within the project boundaries are classified as Class B High Quality Water by the North Carolina Division of Water Quality ( NCDWQ) Class B waters are deemed suitable for aquatic life propagation and primary recreation ( NCDWQ 2010) High quality water is excellent water quality based on biological and physical /chemical characteristics through NCDWQ monitoring They are not on the 303(d) list of impaired streams ( NCDWQ 2010) The Boone Fork watershed upstream of the confluence with Deep Cove Creek is 0 9 square mile and downstream of the confluence the watershed area is approximately 1 7 square miles (Figure 2) Deep Cove Creek s watershed is approximately 0 8 square mile (Figure 2) The UT to Boone Fork at the bank stabilization site is approximately 0 1 square mile (Figure 2) Boone Fork and Deep Cove Creeks are identified as perennial streams on the USGS map while the UT to Boone Fork is an intermittent stream Land cover in the watersheds is predominately forest with some areas recently being logged Additionally there are a few USFS roads in the watershed and a primitive campground Stream impacts appear to be a result of historic agriculture and logging practices The active stream bank erosion resulted in downstream aggradation and stream channel widening that further degrading habitat Riparian buffers are largely intact and expansive except where the campground is adjacent to Boone Fork Riparian buffers along the campground range from 20 ft to 100 ft Thirteen sites totaling 528 if of stream with eroding stream banks and poor aquatic habitat have been identified on Boone Fork (Sites 1 — 13 Figures 3 6) A description of the sites can be found in Table 1 The sites range from 15 if to 80 if in length At most sites the stream bank is eroding at the toe of the slope below the tree root zone Therefore the trees are not providing adequate bank stability Boone Fork s riffle cross section bankfull width at Site 6 was 22 2 ft bankfull mean depth was 0 96 ft bankfull maximum depth was 2 0 ft and cross sectional area was 21 3 ft2 (Figure 4) The riffle s width /depth ratio was 23 0 and the entrenchment ratio was 3 4 Broad level channel classification values indicate that Boone Fork at Site 6 is a C stream type The pool bankfull width and Site 10 was 22 7 ft bankfull mean depth was 18 ft bankfull maximum depth was 2 8 ft and cross sectional area was 39 93 ft2 (Figure 5) The pool s width /depth ratio was 12 9 and the entrenchment ratio was 3 3 The culvert on Deep Cove Creek (Site 14) has been deemed a barrier for fish passage by the USFS (Figures 3 and 8 and Table 1) The five foot diameter elliptical culvert is approximately 2 60 ft long and has a slope of 0 015 Water velocity through the culvert limits passage through the culvert by some fish (Brady Dodd USFS personal communication) Four old log culverts remain in the UT to Boone Fork (Sites 15 18) from historic logging operations (Figures 3 and 9) The culverts have caused stream channel erosion and downstream scour Additionally approximately 1501f of stream bank is eroding and the stream channel is filled with fine sediment (Site 19 Figures 3 and 10) The stream channel is below the tree root zone in areas with steep eroding stream banks The historic culverts and stream bank erosion have increased sedimentation in the Boone Fork Pond Bank scour is also occurring behind the outfall pipe to the Boone Fork Pond (Site 20 Figures 3 and 11) The outfall pipe is approximately 4 5 ft above the water elevation of the plunge pool this has created back eddies and bank scour that has eroded the bank Proposed Improvements All proposed enhancements are described in Table 1 The stream channel s design dimensions are be based on the mountain and piedmont regional hydraulic geometry curve data for riffles (Table 2 Harman et al 1999) and onsite conditions Eroding stream banks and habitat will be enhanced on the thirteen sites on Boone Fork (Figures 3 — 6) The proposed pool at Site 6 on Boone Fork would have a design cross section bankfull width of 20 6 ft bankfull mean depth of 1 7 ft bankfull maximum depth of 2 7 ft and cross sectional area of 34 5 ft2 (Figures 3 4 and 6) The proposed pool s width /depth ratio would be 12 3 with an entrenchment ratio of 3 6 The proposed riffle at Site 10 would have a design bankfull width of 19 7 ft bankfull mean depth of 13 ft bankfull maximum depth of 2 1 ft and cross sectional area of 26 2 ft2 (Figures 3 5 and 6) The riffle s width /depth ratio would be 14 8 with an entrenchment ratio of 3 8 The riffle would still be classified as a C stream type To improve fish passage through the culvert on Deep Cove Creek (Site 14) we propose to decrease the water velocity through the culvert by raising the water elevation within the culvert (Figures 3 7 and 8) A rock cross vane will be installed to raise the head of the riffle downstream of the culvert by approximately one foot The elevation of the stream channel will be stepped down to the existing stream channel elevation through two additional cross vanes The stream channel will be reshaped based on the regional hydraulic geometry curve values and onsite conditions The eroding stream banks on the UT to Boone Fork (Sites 15 19) will be stabilized and aquatic habitat enhanced by removing the existing culverts reshaping the stream banks and installing rock and log vanes (Figures 3 9 and 10) The bank behind Boone Fork Pond s outfall pipe (Figure 3 and 11) will be stabilized by installing non woven filter fabric with a layer of rip rap on top Typical designs of the proposed in stream structures are shown in Appendix A All logs root wads and brush material used for structures will be harvested on site Disturbed stream banks will be reshaped to 1 2 to 1 3 slopes and stabilized with coir fiber matting The clearing of riparian vegetation will be minimized and primarily limited to eroding 3 stream banks Salvaged woody vegetation and sod mats will be used to re vegetate the disturbed stream banks wherever possible These areas also will be seeded with a temporary and permanent native riparian seed mix (Table 3) and mulched with straw Two hundred and fifty live stakes and 200 one gallon containerized trees and shrubs will be planted on disturbed stream banks (Table 4) Trees and shrubs will be planted in higher densities along the outside of meander bends and at structures Estimated quantities for equipment materials and supplies are listed in Table 5 Sediment and Erosion Control A Certificate of Plan Approval from the North Carolina Division of Land Resources Land Quality Section is not required for this project because only 0 5 acre of land will be disturbed However standard erosion and sediment control practices will be used (see details in Appendix A) During construction equipment will only access the stream when absolutely necessary For this project it is anticipated that most of the track hoe work can be accomplished from the top of the bank All construction materials including rock root wads logs and erosion control materials will be stockpiled at a central location at the site To limit disturbance of soils all equipment will travel along existing USFS roads and identified travel corridors Disturbance of soils will be limited to only what work can be accomplished and stabilized on a daily basis As a structure is completed the site will be sloped stabilized with sod mats or re seeded Any stockpiled soils or disturbed areas on steep slopes will have erosion control fencing installed as needed Once the banks are sloped they will be hand seeded with a native all purpose seed mix (10 lbs pure live seed per acre) that was prepared for this region and browntop millet (40 lbs per acre) or winter wheat/rye grain (120 lbs per acre) (Table 3) The surface of the sloped bank will be covered with sod mats salvaged from the site or with coir fiber erosion control matting These materials will be anchored in place with 18 in long hardwood stakes Spill Containment All equipment supplied by the contractor will be in good working order and will not be leaking any fluids that could contaminate the stream or property In case of an accidental spill of hazardous materials (hydraulic fluids gas oil) two Attack Pac emergency spill kits will be on site during construction Any spills of hazardous materials will be cleaned up immediately with contaminated soils disposed of according to state regulations Conclusion Completion of the proposed stream enhancement work will address the residual stream impacts from historical land use practices The light touch approach will minimize disturbance to the riparian area while improving aquatic habitat sediment transport and bank stability Improved fish passage on Deep Cove Creek will benefit both game and non game fish 4 Additionally the reduced sediment in Boone Fork pond will extend the life of the pond and improve angler opportunities References NCDWQ (North Carolina Division of Water

Apply temporary and permanent seed mixture, fertilizer, and lime to disturbed soils. 2. Apply mulch at a rate of one to two tons per acre. No more than 25% of the ground surface should be visible after application. 3. Anchor mulch using 700 g/m2 coir matting to resist wind and runoff 4. To secure the matting, bury the upslope end in a trench no less than six inches deep, cover with soil, and tamp firmly. Do not stretch the matting during application. 5. Use 24 in wood stakes across the top, spacing every 3 feet around the edges and bottom. Each strip of matting should be staked down in the middle every three feet using live stakes and or biostakes. 6. Where two strips are laid side by side the adjacent edges should be overlapped three inches and staked together.
