Describe the existing conditions on the site and the general land use in the vicinity of the project at the time of this application: Conditions at the site consist of a degraded stream channel, rapidly eroding streambanks and a narrow, poorly vegetated riparian corridor/buffer. These conditions are attributable to a variety of historic land uses that have reduced the width of the stream's buffer, point and non-point pollutant sources that have degraded water quality in the stream, increasing stormwater inputs, and damages resulting from high flows produced from intense storm events. Cross sections, surrey data, and other information that depicts the current condition of the Unnamed Tributary to White Oak Creek and the surrounding watershed are included as Figures 1 through 12. The creek's classification ranges from a G6 to F6b stream by the Rosgen Classification of Natural Rivers. The land in the vicinity of the project can generally be classified as livestock pastures, forest, a rural private healing center, and rural residential development. 3b. List the total estimated acreage of all existing wetlands on the property: Wetlands do not appear to exist at the site based on visual observation and referencing the National Wetlands Inventory. 3c. List the total estimated linear feet of all existing streams (intermittent and perennial) on the property: Approximately 3,800 linear feet of stream exist on the properties and include the Unnamed Tributary to White Oak Creek. 3d. Explain the purpose of the proposed project: Streambank stabilization, stormwater management, and enhancement of riparian vegetation will improve water quality in the stream by reducing sediment loads, other contaminants, and water temperature. Establishment of a nearly contiguous riparian buffer will allow the stream to function more naturally and will enhance aquatic and terrestrial habitat. 3e. Describe the overall project in detail, including the type of equipment to be used: The principle goals of this project is to assist the streams evolution toward a stable, more naturally functioning system. The project's design and construction are focused on the following design elements. 1) Preserve existing high-quality riparian plant communities that are intact and not immediately threatened by ongoing, unnatural, lateral, and down-valley migration of the stream channel. 2) Place a permanent deed restriction on both sides of the stream on the Adawehi property (Barber property will not include a deed restriction) with a minimum 25-foot wide riparian buffer on both sides of the stream. 3) Preserve stable streambanks and existing low-flow channel morphology beneficial to a naturally functioning stream. 4) Install and increase the width of a stable accessible floodplain for the stream, slightly below calculated bankfull elevation by installing bio-engineered geolifts, log-vanes, and by grading unstable, over-steep and poorly vegetated streambanks to create a primary bankfull floodplain bench. 5) Create stable streambanks by simultaneously reducing existing streambank slope, installing and making accessible secondary benches located above the primary bench (designed to accommodate higher than bankfull flows), installing micro topographic features into floodplain benches, and by mimicking existing stable terrain. 6) Retention of native topsoil, organic debris and live plant material sourced from the disturbance of existing terrain during the creation of the primary bench and stable streambanks and incorporation of these retained elements into the completed floodplain benches and stabilized slopes so that restored streambanks will establish and support deep-rooted, riparian and wetland plant communities as described in the Vegetation Plan attached as Appendix A. 7) Install and establish a variety of live native plant materials in various stages of succession on the accessible floodplain, stabilized slopes, and in areas where deep-rooted native vegetation is sparse within the riparian buffer. 8) Remove large exotic invasive plant communities existing within the stream buffer by pulling plants by the roots where possible and by cutting larger plants at the base and immediately spraying or painting stems with an approved herbicide. 9) Install in-stream structures, where necessary, to direct stream flow away from healing streambanks. Structures will be constructed primarily of large woody native material harvested duing construction. 10) Rebuild specific streambanks by constructing geolifts, which use high strength coir matting and lifts of native fill material to provide stable side slopes. Equipment used to accomplish the restoration work described above will include small track-mounted excavators equipped with buckets and hydraulic thumbs, various sized track and rubber-tired loaders, and dump trucks to transport and stockpile materials. Various hand tools will also be used throughout the project. Restoration will generally be completed from upstream to downstream. Heavy equipment access roads and material stockpiling areas are indicated on Figures 3 through 11. Operation of heavy machinery in the water will be avoided to the extent practical in order to complete the work described in this application. Most streambank stabilization work will be completed from the streambank Sedimentation and erosion control practices will be implemented throughout the project and will consist of: 1) only working in dry weather during low-flow conditions, 2) only exposing areas of soils that can be stabilized at the end of each work day, 3) installation of temporary silt fence at the top of disturbed banks, at the toe of staging and stockpile areas, and on the downslope side of any work areas outside the streambanks 4) installation of temporary berms at the top of disturbed banks, and 5) installation of seed, coir soil matting, and straw mulch.

Specifically describe measures taken to avoid or minimize the proposed impacts in designing project. Identification of high quality riparian and wetland areas will be avoided during the project and placed in to the permanent deed restriction if those areas lay within the 25-foot buffer area. Sequencing of construction will ensure that all disturbed areas are stabilized at the end of each work day. Standard sedimentation and erosion control practices will be used. Stormwater BMPs will be installed as appropriate. Please refer to Figures 1-12 and D1-D6 for plan drawings and details. 1 b. Specifically describe measures taken to avoid or minimize the proposed impacts through construction techniques. On behalf of the Polk County SWCD, Altamont will provide contractors engaged in the implementation of this work both written and verbal onsite instruction of all impact avoidance statements provided below. All heavy equipment will be kept out of the stream channel during streambank stabilization work to the extent practicable. Disturbance of the channel bottom, streambanks, and equipment access areas will be held to the minimum extent necessary to allow for completion of the bank stabilization work. Work will generally be conducted in an upstream-to-downstream direction. Stream flow will be diverted away from work areas with the use of sandbags during normal and low flow conditions. Work will be completed in stages such that segments of the project will be completed and stabilized, on a daily basis. Temporary grass/grain cover will be planted on all bare soil within one day after ground disturbing activities are completed. Tall fescue or other exotic grasses or plants will not be used in riparian areas. Herbaceous, woody shrub, and tree vegetation will be installed during an appropriate time of year on the primary floodplain and streambanks upon completion of bank stabilization work. Altamont will provide a site manager to inspect and supervise contractor work on a daily basis to help ensure that impact avoidance instructions are being followed. Sediment and erosion control measures will be used at all disturbed areas and will be maintained in order to keep sediment and sediment laden stormwater out of streams. Please refer to Figures 1-12 and D1-D6 for reference. 2. Compensatory Mitigation for Impacts to Waters of the U.S. or Waters of the State 2a. Does the project require Compensatory Mitigation for ?

Does this project require a Stormwater Management Plan? ? Yes ® No 2c. If this project DOES NOT require a Stormwater Management Plan, explain why: This project consists of streambank stabilization, riparian buffer restoration, and placing riparian lands into conservation, of which clearing, grading, and excavating will be limited to near the stream and/or in the stream. Erosion and sedimentation control measures such as silt fence and mulching and seeding will be implemented in areas such as top of bank, earthen material stockpile areas, and temporary construction access roads. Land disturbance will be less than five acres but greater than one acre. Therefore, an erosion and sedimentation control permit will be applied for and obtained from the NCDENR Land Quality Section prior to commencement of construction. Upon receipt of the state-issued erosion and sedimentation control permit, the project will be covered by a state NPDES Stormwater General Permit for construction-related activities from the Division of Water Quality. 2d.

VERIFY THAT COBBLE SIZED MATERIAL OR LARGER MATERIAL (75 MM/2.9 INCHES OR LARGER) EXSITS IN THOSE LOCATIONS FOR BASE STABILITY. 3. IF COBBLE SIZED MATERIAL DOES NOT EXIST IN THESE LOCATIONS, RIP RAP OF THE SAME APPROXIMATE SIZE THAT BE PLACED ON THE CHANNEL BOTTOM OR STREAMBANK TO A MINIMUM THICKNESS OF SIX INCHES, OR LARGE WOODY DEBRIS MAY BE USED A BASE. 4. IN LOCATIONS WHERE GEOLIFTS ARE TO BE INSTALLED NEAR EDGE OF THE WATER, A LOG BASE MAY BE PLACED JUST ABOVE NORMAL WATER ELEVATION. 5. 700 - 900 GRAM PER SQUARE METER MINIMUM COCONUT COIR FABRIC WILL BE USED AS THE FABRIC MATERIAL. INSTALLATION 1. LAY COIR FABRIC PERPENDICULAR TO STREAM FLOW FROM AN UPSTREAM TO DOWNSTREAM DIRECTION, OVER AN AREA THAT CAN BE COMPLETED AND STABILIZED DURING THAT WORKING DAY. 2. COIR FABRIC WILL BE ROLLED OUT LENGTHWISE, PERPENDICULAR TO STREAM FLOW, SUCH THAT IT EXTENDS THE INTENDED GEOLIFT LOCATION TO APPROXIMATELY EIGHT FEET INTO THE CHANNEL. DOWNSTREAM SECTIONS OF COIR WILL OVERLAP UPSTREAM SECTIONS WHEN INITIALLY LAID OUT. 3. COBBLE, RIP RAP, AND SOIL MATERIAL SOURCED FROM NEARBY OR ADJACENT BANKFULL BENCHING AND STREAMBANK GRADING WILL BE USED AS FILL MATERIAL FOR EACH INDIVIDUAL SOIL LIFT. 4. SOURCED SOIL WILL BE CAREFULLY PLACED IN SIX INCH LIFTS AND COMPACTED WITH THE BUCKET OF THE EXCAVATOR OVER THE AREA UNTIL A THICKNESS OF APPROXIMATELY 12 INCHES OF COMPACTED MATERIAL IS ACHIEVED. 5. CAUTION WILL BE USED NOT TO SPILL UNCONSOLIDATED MATERIAL IN THE WATER. 6. APPROXIMATELY THREE FEET OF THE NOSE OF THE GEOLIFT CLOSEST TO THE WATER WILL BE SEEDED WITH THE RIPARIAN SEED MIX SPECIFIED IN THE VEGETATION PLAN AND MULCHED WITH STRAW. 7. COIR FABRIC EXTENDING FROM BENEATH THE COMPACTED AND SEEDED SOIL WILL BE TIGHTLY AND CAREFULLY WRAPPED AROUND THE NOSE OF EACH LIFT, AND STAKED IN PLACE USING DEAD STOUT STAKES, STARTING AT THE PIECE OF COIR FURTHEST DOWNSTREAM AND MOVING UPSTREAM ONE PIECE AT A TIME. 8. WRAPPED COIR SHOULD EXTEND APPROXIMATELY SIX FEET OVER THE COMPACTED SOIL LIFT TOWARD THE NEAR BANK SO THAT PLACEMENT OF THE FOLLOWING LIFT WILL HOLD THE PRECEDING LIFT IN PLACE. 9. THE TOP EDGE OF EACH PIECE OF COIR FABRIC PARELLEL TO STREAM FLOW SHALL BE TRENCHED INTO THE GROUND TO A MINIMUM DEPTH OF SIX INCHES. 10. A LIVE BRUSH MATTRESS, OF TREE SPECIES SPECIFIED FOR LIVE STAKES, WILL BE PLACED PERPENDICULAR TO STREAM FLOW BETWEEN EACH 16 INCH COIR WRAPPED SOIL LIFT. 11. LIVE BRUSH MATTRESS MATERIAL SHALL BE HARVESTED FROM THE TIPS OF SPECIFIED TREE SPECIES BRANCHES AND SHALL BE LESS THAN TWO YEARS OLD AND SHOULD BE FIVE TO EIGHT FEET IN LENGTH. LIVE BRANCHES WILL BE PLACED GROWTH END OUT AND ROUGHLY ADJACENT TO ONE ANOTHER SUCH THAT ONE TO TWO FEET EXTENDS BEYOND COIR WRAPPED LIFTS. 12.

Please refer to Figure 1 for reference. The focus of this plan is to describe how vegetation existing along the UT can be managed and preserved, and how vegetation will be established in areas that are disturbed as part of the streambank project. This vegetation plan largely applies to areas identified as the riparian buffer enhancement area in Figures 4 - 11. Riparian buffer enhancement areas were developed as generally 25-foot wide areas, adjacent to the UT. This plan specifies how the riparian buffer enhancement areas will be prepared for planting, the type of plant stock to be used (e.g. seed, bare root, hardwood cuttings, and container), and how and where specific plant species will be installed in order to achieve the greatest survival rate, and how biological diversity within the riparian buffer will be achieved. This plan also addresses vegetation establishment and soil stabilization of disturbed areas outside of riparian buffers (e.g. on haul routes, access roads, equipment staging areas, stockpile areas, and other land disturbed as part of the streambank stabilization project). Figures 4 - 11 depict locations of work areas for the project. 2.0 Pre-construction Vegetation Identification The UT will be surveyed by subreaches at the beginning and throughout the project to identify and mark large non-native exotic invasive (NNEI) plant communities, suitable transplant material, quality plant communities to be avoided, and organic material to be reused. High quality, riparian plant material and communities, currently existing along the UT streambanks will be avoided. Immediately before heavy equipment work begins, a vegetation team led by a qualified environmental scientist will survey the reach and identify and mark: • Existing native vegetation in proposed work areas that will be disturbed and is suitable for transplant • NNEI plant communities that should be eradicated, including but not limited to Chinese Privet, Multiflora Rose, and Japanese Honeysuckle • Native vegetation and high-quality plant communities that should be avoided • Organic material suitable for the construction of proposed structures and geo-lifts It will be the responsibility of the contractor to coordinate with the qualified environmental scientist and engineer prior to initiating grubbing and grading work, that the above listed items have been identified and marked. Identification and marking transplant material will allow the contractor selected for the project to dig and stage transplant material prior to construction of bank stabilization, and to rapidly replant the material once construction in a particular area is completed. 3.0 Site Preparation for Grading Work Only vegetation that is located immediately adjacent to failing banks, that is being threatened by erosion, and that must be removed in order to stabilize streambanks, install structures and gain access to work areas, will be disturbed. Additionally, the topsoil, organic debris, and live plants that exist in areas to be disturbed will be retained, recycled, and reused as topsoil, structures, and transplants on stabilized banks and floodplain benches as part of this project. Large trees that are removed for the project that will not be reused for structures are to remain on-site for the property owner's use.

Dory Vegetation Plan April 25, 2011 Tributary to Whiteoak Creek Streambank and Restoration Stabilization Project Page 2 Construction. of this project is designed to take place in the late fall, winter,'and/or early spring when tree and shrub plant species are dormant. As the work areas, designated in Figures 4-11, are accessed and streambank stabilization measures are constructed in areas that are unstable, poorly vegetated, over-steep, and eroding, contractors are instructed to conduct work in the following sequence: • Carefully remove native plant materials suitable for transplant that have been identified and marked by a qualified environmental scientist, and stage them in a nearby location where they can be temporarily hilled in and watered until they are quickly replanted on the installed floodplain and stabilized streambanks. • Remove marked NNEI plant communities that exist within designated work areas and access routes with both available machinery and by hand, and haul to an approved burn area. Other NNEI plant communities that exist outside areas to be disturbed but inside the 25-foot wide riparian buffer will be removed by hand. It may be necessary to acquire an air permit from NCDERN Division of Air Quality prior to burning brush. • Remove and stockpile in a nearby and suitable location, organic material, e.g. large woody debris suitable for use as in-stream hydraulic structures, streambank toe protection and geolifts. • As grading is conducted, segregate nutrient and organic-rich topsoil from less fertile soils and stockpile nearby for immediate reuse on the primary floodplain bench and stabilized banks. • In order to minimize the release of sediment during bank stabilization, large sandbags may be used during low flow conditions to divert the stream flow away from the work area (see attached detail Figure D1O). Retained and stockpiled materials described above will be reused and replanted immediately during construction of the primary floodplain and streambank. 4.0 Non-native Exotic Invasive (NNEI) Vegetation In order to achieve success in permanently removing NNEI plants, and in order to reduce the risk of spreading NNEI vegetation to un-impacted areas of the site, NNEI plant removal will take place over the entire buffer area along the stream bank stabilization project reach. NNEI plants will be controlled by removing the plants by the roots, cutting and spraying or cutting and painting, undesirable plants immediately after they have been cut, with a water quality approved herbicide such as triclopyr. Where appropriate, the removed NNEI plants will be burned at an approved location near the work site. Burn locations will be approved by permitting agencies and a burning permit will be obtained and maintained at the job site at all times while the project is underway. If burning is approved, no aid of chemical accelerants, such as gasoline or diesel, will be used to ignite the fires. The vegetation team will be directed not to damage quality vegetation and to keep disturbance of the buffer to a minimum as NNEI plant removal and transplant material tagging activities are conducted. If weather conditions permit and an appropriate location is selected, burning of removed NNEI vegetation may be the preferable solution for disposal due to cost of transport, proximity to the work area, and the reduced potential to spread NNEI plants to surrounding areas. 5.0 Sourcing of Plant Material Plant suppliers will be selected from the Wetland (Native) Plant Vendor List for North Carolina, specified by the North Carolina Department of Environment and Natural Resources (NCDENR)-Division of Water Quality (DWQ) or be preapproved by the project engineer.

Plant species selected to be installed in buffers along the project reach were selected based on a qualitative riparian vegetation assessment of the project area. Although the riparian buffer is impaired and altered in many locations, areas do exist where the buffer is relatively undisturbed and these areas exhibit a diverse variety of native plants in various stages of natural succession. Vegetation observed in these areas was used as a reference for the recommended native herbaceous plant, shrub, and tree lists (Tables 1 and 2) attached to this plan. Plant material specified for this project will consist of • native riparian seed mixes (to be used on streambanks) • sediment and erosion control seed mixes (to be used to stabilize disturbed soils beyond the riparian buffer area) • bare root trees and shrubs • container herbaceous plants, trees, and shrubs • hardwood cuttings and whips • transplant vegetative material that will be harvested before the area is disturbed Planting of herbaceous plants, trees, shrubs, and hardwood cuttings will conform to the specifications outlined in the NCDENR Guidelines for Riparian Buffer Restoration included in Appendix A. Staging areas for plant material and equipment will be located in upland areas away from surface water and outside of the 50- year floodplain. Irrigation of riparian plantings will take place as needed. 6.1 Floodplain Benches and Stabilized Streambanks The bulk of native vegetation will be installed in areas where streambanks are stabilized and along floodplain benches. These areas, indicated on Figures 4 - 11, are locations where streambanks are in poor condition, are actively eroding, and are essentially void of quality riparian vegetation. These areas are also where the greatest disturbance to the existing bank will occur as part of this project and where the majority of in-stream structures and grading of the streambanks to a stable slope will take place. Installed floodplain benches and slope stabilization areas will be constructed, stabilized, and vegetated in sequence, beginning consecutively at the upstream ends of the project reach. Each of these individual areas will be completed before land-disturbing activities begin in the next area. All disturbed areas on streambanks will be stabilized at the end of each work day. Construction sequencing and preparation for planting will generally take place in the following order while continuously monitoring and avoiding existing native and beneficial plants: 1. Clearing and grubbing to remove NNEI and harvest transplant material. 2. Bankfull benches and geo-lifts will be installed. 3. Streambanks landward of the bankfull bench will be graded to a stable slope. 4. In-stream structures will be installed per the descriptions in the construction diagrams.

Floodplain benches will be fertilized. Fertilizer amounts will be interpreted from an agronomic soil test report from a composite soil sample collected from eroding streambanks within the project reaches if possible. 6. Exposed areas of geo-lifts will be seeded with seed mixes specified below, fertilized, and mulched with straw prior to coir fabric being wrapped over the lift and staked in place. 7. Disturbed areas below the top of the existing streambank will be hand-seeded with a riparian buffer seed mix and mulch. See attached Table 2 for proposed plant species. 8. Disturbed areas between the water's edge and 1.5 times bankfull elevation will be stabilized with 700- gram-per-square-meter coconut coir fabric placed over cultivated, fertilized, seeded, and straw- mulched soil. Coir fabric will be trenched in on all sides, and staked in place with wooden and live stakes per specification. 9. Areas between 1.5 times bankfull and the top of bank will be seeded with a sediment and erosion control seed mix, and an approved mulch and tackifier will also be installed. 7.0 Plant Quantities and Installation Native species of shrubs and trees will be planted in stabilized areas of the streambank within the 2.41 acre riparian buffer area for the streambank project. 7.1 Seed Mix A native riparian seed mix will be installed on disturbed areas within the 25-foot riparian buffer area at a rate of 15 pounds per acre, meaning 42 pounds of riparian seed mix will need to be installed over the 2.78 acres of disturbed riparian areas. Herbaceous species to be included in this mix are listed in Table 2 and are taken from ERNST riparian buffer seed mix # 178. In addition to the riparian seed mix, a cover or nursery crop will need to be installed at a rate of 10 pounds per acre. 28 pounds of nursery crop will be installed and should be a species appropriate for the season. Sediment and erosion control seed mixes will be acceptable for disturbed areas beyond the 25-foot riparian buffer area. Seed mixes used outside the buffer area will be required to include three varieties of non- invasive seed, one variety being an annual grain suitable as a nursery crop and will be applied at a rate of 30 pounds per acre, meaning 30 pounds of riparian seed mix will need to be installed on the anticipated one acre of disturbed area outside of the riparian area. Before the riparian buffer area and the area beyond the riparian buffer are seeded, the disturbed area will be cultivated at a minimum with a hard rake or preferably with a tool capable of cultivating soil to several inches in depth. Fertilizer will be applied based on the recommendation of a soil test report. Seed will then be applied and mulched with straw and tackifier and watered regularly until a six inch stand of vegetation is established. Hydroseeding of these areas with a similar seed mix will also be acceptable; however disturbed areas will still require cultivation prior to spray application. If agricultural crops are disturbed outside of the 25-foot riparian buffer area, seed of that crop or acceptable to the landowner will need to be installed. 7.2 Bare Root and Container Plants Varieties of large trees will be selected from Table 1 and equal numbers of at least six species of trees on the list must be installed. Similarly, small trees and shrubs will be selected from the attached Table 1 list and at least eight species of small trees and shrubs from the list must be planted. Trees will be planted at a density sufficient to provide 320 trees per acre at maturity. To achieve this density, approximately 681(8x8 P:\Polk SWCD NRCS\DWR Barber Adawehi 20 10\Tech n ica ]\Vegetation Plan\Vegetation Plan.Docx Vegetation Plan April 25, 2011 Tributary to Whiteoak Creek Streambank and Restoration Stabilization Project Page 5 feet spacing) trees per acre will be planted initially. Shrubs will be planted at a density sufficient to provide 1,200 shrubs per acre. These species and densities are taken directly from the Guidelines for Riparian Buffer Restoration produced by the NCDENR, attached as Appendix A. These densities include transplant material that will be sourced from areas to be disturbed by streambank stabilization. The riparian area that will be planted for this project is approximately 3.5 acres. Therefore, approximately 2,400 large trees and 4,200 small trees and shrubs will need to be planted. Seventy five percent of the overall plant material (including small trees/shrubs and large trees) can be in the form of bare root instead of container plants (3,150 bare root small trees and shrubs, 1,050 container small trees and shrubs, 1,790 bare root large trees, and 600 container large trees). Container Plants must be in minimum three-gallon pots and trees and shrubs must be three feet tall from the top of the pot. Additionally, herbaceous container plants can be installed. The density of herbaceous plants per acre installed may reduce the per acre seeding requirement per approval by the environmental-scientist or engineer. Bare root plants will be planted where coir matting has been installed, approximately from waters edge to 1.5 times the bankfull elevation. Container plants will be installed within the 25 foot riparian buffer area where coir matting is not present. Bare root and container vegetation will be planted in areas where they have the best chance for survival, (i.e. water loving plants will be planted in wetter areas of the site or closer to the water and shade loving plant will be planted in shadier areas of the site). 7.3 Live Hardwood Cuttings and Whips Live hardwood cuttings (or livestakes) and whips will be planted near the water's edge and used to help secure the coir mesh and to help rapidly stabilize soils at the toe of the streambank. Hardwood cuttings and whip species are specified in Table 1. Hardwood cuttings should be taken from the ends of branches, including the terminal bud (tip). Hardwood cuttings must be from wood that is one to three years old. Hardwood cuttings can range from 8 - 24 inches long, and a minimum of 3/8 inch diameter. Thick, young stems root better and grow more vigorously. The bottom cut should be at a 45 degree angle. Cut off any side shoots close to the main branch. Side shoots of sufficient size can be used for more cuttings. Whips are thin branch (less than 3/8 inch diameter) cuttings from hardwoods. Hardwood cuttings and whips will be harvested when the plants are dormant and refrigerated if stored in air temperatures above 40 degrees Fahrenheit, until installation. Additionally, hardwood cutting and whips will be dipped in a root growth agent similar to Rutone prior to installation. Hardwood cuttings will be installed along both sides of the entire 3,800-foot project reach, close to the water's edge. One hardwood cutting per linear foot will be installed in a staggered pattern up to two feet from the water's edge on both sides of the stream, therefore, approximately 7,600 hardwood cuttings will need to be installed. One whip per linear foot will be installed on the two bottom layers of constructed geolifts. Approximately 700 linear feet of geolifts will be installed, therefore, a minimum of 1,400 whips will need to be installed at the geolifts.

However, small test plots in areas near the top of the bank may not be irrigated in order to evaluate the effects of irrigation and cost benefit. Irrigation will be conducted using a trash pump, hose, and diffusing nozzle and will utilize water pumped from the stream channel. The stream buffer will be monitored and irrigated if necessary until a six-inch stand of herbaceous vegetation is established on all disturbed areas of the site.

VJ JLLlll PROGRAM p, N c for (i Cw~ N.C. Department of Environment and Natural Resources Ecosystem Enbancement Program October 2004 Purpose ofthese Guidelines Riparian buffers have been identified as a valuable tool for protection of water quality when properly designed and established in the appropriate landscape setting. For this reason, the goal of the Ecosystem Enhancement Program (EEP) is to implement projects to restore riparian buffers that have the greatest value for reducing pollutants in our surface waters as well as provide important aquatic and wildlife habitat. The purpose of these guidelines is to provide the technical information necessary for the successful planning and establishment of riparian buffers. The guidelines are intended for use by private consultants in developing restoration plans for the EEP but should also have utility for private landowners as well as local governments involved in the restoration of riparian buffers. Criteria for Priority Riparian Buffer Restoration Projects A number of factors determine the success of particular riparian buffer restoration projects. In addition to the physical characteristics of the site, issues such as land costs, land ownership, and logistical constraints must be taken into consideration. The following physical characteristics are intended to provide general guidance when identifying sites and are not intended to exclude sites that may have merit based on other criteria. • Woody vegetation absent or sparse (less than 100 stems per acre that are > 5 inches diameter at breast height) measured within 50 feet of intermittent and perennial streams, lakes, ponds, and shorelines. • Adjacent to headwater streams or those streams defined as first, second, or third order. • Project length greater than 1,000 feet (for projects implemented by the EEP). • Ditches, gullies, or evidence of concentrated flow within 50 feet of intermittent and perennial streams, lakes, ponds, and estuaries. • Adjacent source of nitrogen including cropland, pasture, golf course, residential development, ball fields, etc. • Water table depth within three to four feet of surface as determined by characteristics of soil cores. Components ofa Riparian Buffer Restoration/Enhancement Plan Site Asses5mel7 t The riparian area to be restored should be evaluated with respect to these factors that control the viability of riparian plants: • Soil moisture • Soil pH • Soil texture • Seasonal high water table depth • Flooding potential • Aspect, topography, and microtopographic relief Site Pt-ep'r-4ti012 The restoration/enhancement plan should address these items regarding preparation of the site for planting: • Plow or rip site to improve compacted soil and/or eliminate areas where channelized flow has developed. • Control of sod-forming grasses such as fescue and Kentucky bluegrass that will compete with plantings for nutrients. • Control of invasive, exotic plants that would hinder the re-establishment of woody vegetation. Proposals for pesticide use should always be reviewed by the North Carolina Division of Water Quality staff to insure compliance with the Neuse and Tar-Pamlico Riparian Buffer Rules. Common Invasive Exotic Plants in North Carolina Ailanthus altissima (Tree-of-Heaven) Albizia julibrissin (Mimosa) Elaeagnus umbellata (Autumn Olive) Hedera helix (English Ivy) Lespedeza cuneata (Korean or Sericea Lespedeza) Ligustrum sinense (Chinese Privet) Lonisera japonica (Japanese Honeysuckle) Microstegium vimineum (Japanese Grass) Paulownia tomentosa (Princess Tree) Pueraria lobata (Kudzu) Rosa multiora (Multiflora Rose) Wisteria sinensis (Chinese Wisteria) Stabilize areas of bare soil. Refer to the following list for species of grasses/sedge appropriate for soil stabilization. The majority of these species are by necessity not native to North Carolina. At present, there are only a few species of native grasses useful for erosion control that are commercially available. Please note that fescue grasses should not be used for soil stabilization. Fescue grasses, particularly tall fescue, are competitive and will inhibit the eventual re-establishment of native species. 3 Agrosti5.a1b,7 (Redtop) Found in fields, pastures, roadsides, and other disturbed places throughout North Carolina, this native warm season grass should be used sparingly for erosion control and soil stabilization. G3Pexstricta (Se4ge) This sedge occurs naturally in marshes and low meadows throughout the mountains and northern piedmont and coastal plain of North Carolina. This species has utility in a mix for soil stabilization in moist areas. 93ct1li5g1omer4t,3 (Orchar4gra55) This perennial, cool season bunchgrass is a good alternative to fescue because it is less competitive and allows native herbs to colonize the site. Hordeum spp. (Barley) A number of species of barley can be used for soil stabilization. Barley is a cool season, annual grass that when moisture is available will germinate in the fall, stay green during the winter, and then die in the spring as competition for warm season plants increases. Pwicum %ndestinutn Weer Tongue) This native, perennial, warm season bunchgrass can be used in moist low woods primarily in the piedmont and mountains. Pvnicum spp. (Panic Grasses) A number of species of panic grasses can be used for soil stabilization depending on the moisture regime and soils of the site. P,nicum V1rg,3tur7 (Switchgrass) This native, perennial, warm season bunchgrass can tolerate a wide range of moisture regimes. It can be used along streams, in wet or dry woods, brackish and freshwater marshes, sloughs, swales, and low pinelands primarily in the eastern piedmont and coastal plain. Peoni5etumg1,?ucum (Brown Top or Pearl Millet) This fast-growing, robust, annual grass exhibits good drought tolerance which makes this species an important warm season option for soil stabilization. 4 Pha1,Jri5,7ru12dia4ce4 (Reece Canarygrass) A native to North Carolina, this perennial cool season grass is used for the stabilization of pond shorelines, drainage ditches, and streambanks in the mountains and western piedmont. It is established by planting freshly cut stem slips or rhizome fragments. Please note that this species is aggressive and forms large monotypic stands that displace other species. It should only be used if no other species are available. Secale cerevle (Winter Rye or Rye Gra in ) Winter rye is a cold-hardy annual grass that will germinate and grow at low temperatures. By maturing early, it offers less competition during the late spring, a critical time in the establishment of perennial species. Winter rye germinates quickly and is tolerant of poor soils. Sorghum bicolot-(Su4angNss) Only the small-stemmed varieties of this annual warm season grass should be used. Sudangrass is useful for temporary seeding, and it is adapted to soils relatively high in clay content. Seed for common Sudangrass is not always available, but other small- stemmed types may be used, such as the hybrid Trudan. The coarse-stemmed Sorghum-Sudangrass hybrids are not appropriate for erosion control. Riparian Buffer Design Species Diversity and Composition '. The most effective riparian buffers have trees and shrubs to provide perennial ?% root systems and long-term nutrient storage. The design of a riparian buffer can be modified to fit the landscape and the landowner's needs, for example, by replacing shrubs with more trees, substituting some of the trees with shrubs, or incorporating a grass zone. In any scenario, the width of the woody vegetation should be at least 30 feet directly adjacent to the streambank/shoreline. Choose 10-12 species of native trees and/or shrubs appropriate for site based on site assessment and reference conditions. In addition, please note that this list is alphabetical and does not take into account the assemblages of plants found in nature. The inventory of plants found on the reference site can help determine an appropriate assemblage for the restoration site. In addition, the North Carolina Natural Heritage Program's Classification of the Natural Communities of North Carolina: Third Approximation is a valuable reference on natural assemblages of plants (Shafele, Michael P. and Alan S. Weakley, 1990). Typically, there should be at least three or four understory trees for every canopy tree to provide structural diversity similar to mature forests. Where shrub species are incorporated into the planting plan, they should be distributed more densely at outer edge of riparian buffer to reduce light penetration and recolonization by invasive exotic species.

Where grasses are incorporated into the planting plan on the outside of the buffer strip, only native grasses should be used. Native grasses produce a much more extensive and deep root system than commonly used non-native grasses such as fescue. Common Native Grasses Andropogon gerardii (Big Bluestem) Andropogon virginicus (Broomsedge) Arundinaria gigantea (Giant Cane) Eragrostis spectabilis (Purple Love Grass) Panicum anceps (Beaked Panicum) Panicum clandestinum (Deertongue) Panicum hemitomon (Maidencane) Panicum virgatum (Switchgrass) Schizachyrium scoparium (Little Bluestem) Sorghastrum nutans (Indiangrass) Tridens flavus (Purple-Top) Tripsacum dactyloides (Gams Grass) Planting Density Trees should be planted at a density sufficient to provide 320 trees per acre at maturity. To achieve this density, approximately 436 (10x10 feet spacing) to 681 (8x8 feet spacing) trees per acre should be planted initially. Shrubs should be planted at a density sufficient to provide 1,200 shrubs per acre. 10 Plant Size In many cases, the most cost effective and successful size plant material is bare root seedlings. Some species such as the hickories do poorly as bare root seedlings and will be much more successful as containerized seedlings. In either case, tree shelters should be used to accelerate growth and increase survivability of seedlings. In addition, management of competing vegetation after planting is easier, mowing and weed wacker strikes are prevented, herbicides are isolated from trunk contact, and grazing by deer are restricted. The use of tree shelters may only be practical from an economic standpoint for more expensive seedlings of species difficult to establish, such as red oak. Reductions in maintenance costs and increased seedling vigor associated with tree shelters suggest that tree shelter plantings may be a more cost-effective approach than planting unprotected larger material. In urban or other high visibility areas, some specimen trees and shrubs should be incorporated into the planting plan for projects implemented by the EEP. When live stakes or dormant cuttings are incorporated in a planting plan, choose only the previous season's growth. Live stakes should typically be approximately % inch in diameter and three feet long, and dormant cuttings should be approximately '/Z inch in diameter and two feet long. Suppliers of Native Plant Material Local nurseries are the best option in acquiring plants that will be successful. Plants grown from seeds or cuttings collected close to the restoration area will be the most likely to survive and reproduce. Planting Layout The planting plan should indicate that trees and shrubs will be planted in a random pattern. For inexperienced planting crews, pre-labeled flagged wires can be used to mark the random location of plantings. These flags can also be color coded for each particular species. Various colors of spray paint can also be used to differentiate species. Planting Practices When planting seedlings, it is helpful to mark the plants with colored flagging to make them easier to locate during maintenance tasks. The flagging can also be color-coded to mark plants that have died for replacement at a later date. Tree protectors are also helpful for locating plants. Tree seedlings should be kept moist and should not be exposed for extended periods of time. A correctly planted tree should have the. following general characteristics: Planted so that the root collar is slightly below the soil surface. Have the main roots nearly straight or spread out. 11 • Have soil firm around the roots. Have the tree in an upright postion and have it nearly even with the general ground level, not sunk in a hole or raised on a mound. Please note that the Neuse and Tar-Pamlico Riparian Buffer Rules allow for a one time fertilizer application to establish newly planted vegetation. Ongoing fertilizer application is prohibited by these rules. Riparian Buffer Maintenance Control of Grasses and Fortis In the early stages of riparian buffer establishment, competition for nutrients by adjacent grasses and forbs will substantially inhibit seedling growth. Release from herbaceous competition has been demonstrated as the most cost-effective method to accelerate the growth of seedlings. The plan for buffer establishment must incorporate control of the herbaceous layer. Options for weed control include four to six inches of well-aged hardwood mulch, weed control fabrics, or pre-emergent herbicide. Typically, mowing to control weeds will be impractical based on the random distribution of plantings. Weed control should be, continued for three years from the time of planting. Areas of Concentrated Flow During the required five year monitoring period, the riparian buffer should be inspected for evidence of concentrated flow. If concentrated flow has begun to form, a level spreader or other best management practice should be installed to diffuse the flow before it enters the restored riparian buffer.
