Describe the existing conditions on the site and general land use in the vicinity of the project at the time of this application: The proposed project site consists of woodland areas and livestock pasture Surrounding land consists of rural residences, rural roads and farmland. Little White Oak Creek was significantly dama eg d by hurricanes Francis and Ivan in September 2004 Furthermore the proiect area exists in an area used heavily by livestock. These conditions coupled with land disturbing activities higher in the watershed, and storm events more recent than 2004 have left the Little White Oak Creek streambanks in a_ non / poorly vegetated eroding state. The project area is located on the Williams property and runs alongside Little White Oak Creek and one unnamed tributar~pproximately 3,091 feet. The project area is bounded at the upstream end by a cattle fence and by an unnamed tributary entering from river left at the downstream end of the project area. Many damaged areas along. streams and rivers throughout the southeastern United States were repaired through funding_provided by the Natural Resource Conservation Service (MRCS) as part of the Emergency Watershed Protection (EWP program. The NRCS program rectuired economic justification for discrete r~airs and primarily addressed flood damaged areas adjacent to homes or commercial agricultural areas. As a result, the EWP program did not address some severely eroded streambanks adjacent to undeveloped land. The State of North Carolina has provided funding through the DENR Division of Water Resources (DWR) Water Resources Development Project Grant program for dammed areas that were not addressed by the EWP grogram and targets streambanks that are actively contributing sediment to waters of the U.S. reducing water quality. The Williams site has been identified by the Polk County Soil and Water Conservation District as one area eligible for DWR funding and for this project DWR funding will be coupled with the National Resource Conservation Service Cost Share funding to fence cattle out of the stream and to establish a minimum 20 foot buffer between livestock areas and the stream. The project area consists of approximately 3 091 linear feet of stream located along Little White Oak Creek and one unnamed tributary in the community of Mill Spring, North Carolina. The project will address both sides of the creek and the tributary in the upstream portion of the project area. In the downstream portion of the project area only the streambank and riparian corridor on river left will be addressed. One thousand eighty nine linear feet of streambank will be disturbed during the project to width of 20 feet from the edge of water. Approximately 0.90 acres will be disturbed in total including access routes and staging areas. The remaining 2002 linear feet of streambank on river left will be cleared of debris and ag rbage. Exotic invasive plants will be removed and native trees and shrubs will be planted to enhance the riparian vegetation in these areas. Planting of native herbaceous plants, trees .and shrubs in both stabilization and enhancement areas will increase the width of the riparian corridor in the project area to no less than 20 feet from the edge of water along Little White Oak Creek and the tributary A signed Access/Agent Authorization Letter is attached to the signature page of the PCN document. A site vicinity map is included as Figure 1. A Site Plan is including cross-sections profiles and plan views of the project is included as Figure 2. Illustrations for Construction of Structures and Phot~phs and Descriptions of the site are Page 7 of 18 attached The tributary to Buck Creek is classified by the DENR as "C" waters throughout the project area 10. Describe the overall project in detail, including the type of equipment to be used: SUMMARY Using a track mounted excavator streambank slopes along Little White Oak Creek will be benched at or sli hg_tl~above the determined bankfull elevation. Above the bankfull bench, bank slopes will be made less steep and will be adjusted to a final slope of approximately three horizontal to one vertical with out damaging existing_qualit~parian vegetation. In areas where large living trees are too close to the existing bank to allow for such a slope, the slope will be softened as much aspossible without causing damage to trees that are holding the bank in place. Rootwads may be installed just upstream of areas where the bank is steeper to deflect and dissipate stream flow away from the bank. Toe areas of the repaired slopes may be reinforced in higher stress areas with lame angular boulders In these areas one row of boulders will be placed in a footer trench. The footer trench will be lined with filter fabric and rock toe protection will be backed with filter fabric as well. Depending on the vulnerability of the area another tier of large boulders may be placed on top of the footer rock and set back approximately one-two feet in order to match the desired slope of the streambank Void spaces behind the footer and tiers of rock will be back-filled with material that was excavated during the installation of the footer trench. When backfilling~ is complete, excess filter cloth protruding from between the boulders and the backfill will be trimmed to an elevation slightly higher than the elevation of the top of the boulder toe protection. Single veins and cross veins constructed of either large angular rock or hardwood tree trunks may be used to help turn flow in streambends and protect streambanks in high stress areas on the outside of turns in the stream. Live fascines may be buried in the streambank where feasible at an elevation approximately equal to bankfull Fascines will consist of bundles of a variety of live cuttin~is taken from native species of trees The live cuttings used for fascine bundles will be no larger than one inch in diameter and will be approximately three to four feet in length. Tips of live cuttings will be oriented in the same direction but cut to varyinglengths before placement in the fascine bundles. Fascine bundles will be bound together with heave biodegradable twine and placed in trenches with the tips facing in an upstream direction. The live Fascines will take root and Quickly begin to anchor and further strengthen the toe of the streambank slope soon after installation. After the streambank slopes are adiusted and toe protection consisting of boulders rootwads and fascines is installed disturbed non-vegetated areas of the project will be hand seeded with annual rye or similar grain Coir and Jute matting_will be installed over the areas of bare soil, trenched in on all sides and held down b~wooden and live stakes. Seeding of these areas with a native seed mix will follow and caution will be used to keep seed mulch and fertilizer out of the river and above the typical high water elevation in order to reduce the risk of eutrophication. Finally, riparian areas in the remainder of the project area will be enhanced by removal of exotic and evasive plants and planting of sparsely vegetated areas with a variety of native bare-root, container and live-stake trees and shrubs to a width no less that 20 feet from the waters edge. All plantings will be watered in after installation and subsequently, as needed for one year post Page 8 of 18 construction These plantings will help re-establish riparian vegetation within the project area reducing sediment load to the streamzprovide a more stable streambank and future shadin og f the channel Trees and shrubs will be purchased and planted while dormant or during the appropriate planting season The project will include removal of debris (i.e. large trees, brush and trash) form the stream channel and banks Debris that is currently obstructing_water flow, limiting hydraulic capacity of the river channel forcing flow into unprotected banks or is an environmental hazard will be removed Debris that is natural stable and is situated such that it is protecting vulnerable banks will be left in~lace Trees removed as debris and their root balls may be used for bank stabilization and as aquatic and terrestrial habitat as rootwad structures in several locations within the project area Rootwads are planned for use where the existence of large live trees will not allow rg ading of the streambank to a preferable three horizontal to one vertical slope. Trees selected for rootwads will be cut 15 to 20 feet up the trunk from the roots and sharpened to a point with a chainsaw. In locations were rootwads are used a trench will be excavated lame enough to burry a footer log_parallel to the streambank at the toe of the slope. The rootwad will be inserted sharpened trunk first in to the bank and the trunk just above the roots will rest on the footer lo¢ The rootwads will be oriented so that stream flow is deflected away from the streambank to protect lar eg living trees in these locations. Placement of the rootwads at an angle proximately 55 degrees from the upstream bank will provide deflection of streamwater in an effort to preserve near bank mature live trees. Rootwads and footer logs will be installed so that the bottoms of the structures extend to the maximum scour depth of the channel and the top of footer log and bottom of rootwad log are roughly the same elevation as the stream invert. Rootwad trunks will be inserted into the streambank by a track mounted excavator so that the root ball is exposed and at least two thirds of the trunk is buried in the bank. Rootwads and footer logs will be backfilled with material excavated from footer log and rootwad trenches and where necessary will be stabilized on either side with large angular rock or rip rap Equipment used to accomplish the above tasks will include: rubber tired back-how /loader, a track mounted excavator with hydraulic thumb one or two 15 ton dump trucks, and hand tools. A wood chipper may be used to reduce the amount of debris to be hauled away from the site and minimize potential disposal fees Wood chips may be used to mulch areas beyond the top of bank. DETAILS The following activities are~roposed within the project area• An area adjacent to Little White Oak Creek within the Williams property located in Polk County, North Carolina has been identified by the Polk County Soil and Water Conservation District Office as eligible for monies provided by the State of North Carolina through a DWR grant. The Polk County Soil and Water Conservation District Office and Altamont Environmental, Inc. (Altamont) plan to stabilize over-steepened streambanks and enhance the riparian buffer along the 3,091 linear foot project reach. The structures proposed for streambank stabilization at the site are• Rootwads Rock Toe Protection Single and Cross Veins and Live Fascines. These structures coupled with softening of the streambank slope should provide a lasting repair that Page 9 of 18 leaves the project area in a more natural state of equilibrium. Once the streambank is stabilized native species of herbaceous plants shrubs and trees will be planted on the streambanks and in disturbed areas of the site. An Access/ Agent Authorization Agreement is attached to the si na~page of this PCN. A Site Vicinity Mavis included as Figure 1. Cross-sections proposed construction plans, profile of the stream and a plan view of the project area are included as Figure 2. Illustrations for construction structures and photograph and descriptions of the project area are attached at the end of this document. • Before construction at the site begins, existing live trees and vegetation that are identified as stabilizing_the streambank will be flagged to be left in place. Project area boundaries will also be identified and marked. • Some removal of organic and non-native material from the channel may be necessary in areas where the hydraulic capacity of the stream channel has been reduced based upon onsite observations and evaluation of existing cross-sections. Trash that has been dumped along the stream will be removed and taken to an appropriate disposal facility. • Using the track mounted excavator and the backhoe, streambank slopes within the project area will be benched at or slightly above bankfull elevation and adjusted from their near vertical state to a slope of approximately three horizontal to one vertical or flatter except where large living trees close to the bank prohibit grading. In these areas, rootwad structures may be installed and slopes will be softened as much as possible. Some adjustment of the slope before installation of structures will allow for easier access to theproject area will compact the slope and will eliminate the need to access the streambanks from the water. • Debris eg nerally consists of trees stumps, woody material and trash. This material will be removed from the stream channel using the track mounted excavator equipped with a hydraulic thumb. Some of the larger dead trees will be used as rootwads structures within the project. Woody debris removed from the channel will be reused as rootwad structures or disposed of either as firewood, chipped into mulch, hauled to an appropriate landfill or some combination there of. • For streambank areas where rock toe protection is used, a footer trench will be excavated at the toe of the slope. The footer trench will be excavated to a depth of approximately two feet or deep enough to burn each footer rock to a depth equal to three-quarters of its thickness. Ideal dimensions for large angular rock to be used at the site are three feet by two feet b~two feet or larger. Footer trenches will be dug in a downstream to upstream sequence in order to limit the amount of sediment discharged to the stream and limit the flow of water into the trench. Footer trench lengths will be dug in sections equal to the width of the filter cloth to be used for the project in order to limit disturbance of the channel bed material. Completing the project in sections will limit the number of times the trench will have to be re-excavated due to sediment washed in by the stream. Footer trenches at their upstream and downstream locations will be keyed in the streambank so that during_periods of high flow, water cannot get behind the rock toe protection and compromise the structure. • After a section of footer trench is dam, filter cloth will be placed in the trench and a sufficient amount of cloth will be extended u~ the streambank to back the footer and Page 10 of 18 next tier of rock once it is placed. Footer rock of a size described above will then be placed in the trench securing the bottom of the filter cloth in place. • After the footer rock is placed the filter cloth will be held up so that it backs the footer rock while the void behind the footer is backfilled with material that was excavated from the trench. • Alain the filter cloth will be laid on the streambank while the first tier of rock is lp aced atop the footer. This first tier of rock will be placedpartially on the footer and partially on the backfill, set back in a manner to match the slope of the streambank. • Once the first tier of rock is placed on the footer the filter cloth will again be held up so that the remainder of the rock structure can be backfilled. • If live fascines are installed. this will occur when construction of the rock toe and rootwad structures is complete. A trench approximately one foot by one foot will be excavated iust above the rock toe protection structure at an elevation at or slightly above bankfull. Live fascines will be installed in the trench and the trench will be backfilled. Fascine trenches will be excavated to dimensions slightly smaller than the fascine bundle, so that the top of the fascine is exposed. Live stakes will be driven through the fascines to secure them in place. Subsequent growth of the fascines will further stabilize the toe of the streambank as roots interlock with soil matting and rock in these locations. • After streambank slopes are adjusted, and structures are installed all disturbed areas will be hand seeded with annual r~grass or a similar grain. Coir mat will be installed over the completed fascines and bare soil near the toe of the streambank and will extend up the streambank to an elevation above bankfull elevation. Jute mat will be used on the upper portion of the slopes to stabilize soils durin initial growth of vegetation. On-site temporary seeding and mulching will occur on the remainder of bare soil within five days of ground disturbing activities to provide long-term erosion control. • When the construction portion of the entire project area is complete all disturbed areas will be seeded with a native seed mix above typical high water elevation. Care will be taken to keep seed, mulch, and fertilizer out of the stream to prevent the risk of euotrophication downstream. • Post seeding, disturbed areas will be planted with a diverse variety of bare-root container and live-stake native plants, shrubs and trees based on observations made of plants that are naturally occurring within the stream corridor or could exist with in the region. Planting will conform to the guidelines prescribed in the NCDENR Ecos. sy tem Enhancement Program, Guidelines for Riparian Buffer Restoration. Re-seeding will be conducted, as necessary with a native annual and perennial seed mix with a temporary nursery crop of wheat, millet or other gain. Woody vegetation will be planted durin,.g the appropriate planting season or will be kept dormant in coolers until planted. Plantin i~pected to take place no later than early Maw Stabilization of streambanks will require placement of material in wet conditions. In such cases, sand bates, or the equivalent, will be used to deflect water flow away from the work area as well as prevent water from accumulating in the work area. Standard erosion and sedimentation control measures will be utilized throughout the duration of project Care will be taken to avoid adverse affects to adjacent or downstream property owners Page 11 of 18 At the work site, work shall proceed from downstream to upstream to reduce sediment loading_ Staging areas for ecLuipment and material will be placed in upland areas away from surface water and outside of the floodplain. Work will proceed as follows at the work area (as 1. Flag the work limits. 2. Mark live trees and shrubs to be protected. 3. Construct temporary construction entrance /exits, where necessary 4. Place erosion control fencing and other protective measures as necessary S. Adjust streambanks where necessary, install structures, remove exotic species and install native plant material. 6. Inspect and maintain repairs. 11. Explain the purpose of the proposed work: Work being conducted by the Polk County Soil and Water Conservation District Office and Altamont, is being funded through the North Carolina Division of Water Resources grant. The grant is intended to fund projects in storm damaged areas that were not addressed by the federal Emergency Watershed Protection program. The purpose of the project in this specific area is to stabilize the streambanks, restore and widen the riparian corridor along the banks of the Little White Oak Creek within the project area and to reduce the amount of sediment entering the stream by reducing erosion of the streambanks.

Altamont will provide a site manager to routinely inspect and supervise contractor work to help ensure impact avoidance instructions are being followed. VIII. Mitigation DWQ - In accordance with 15A NCAC 2H .0500, mitigation may be required by the NC Division of Water Quality for projects involving greater than or equal to one acre of impacts to freshwater wetlands or greater than or equal to 150 linear feet of total impacts to perennial streams. USACE - In accordance with the Final Notice of Issuance and Modification of Nationwide Permits, published in the Federal Register on January 15, 2002, mitigation will be required when necessary to ensure that adverse effects to the aquatic environment are minimal. Factors including size and type of proposed impact and 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. Page 15 of 18 If mitigation is required for this project, a copy of the mitigation plan must be attached in order for USACE or DWQ to consider the application complete for processing. Any application lacking a required mitigation plan or NCEEP concurrence shall be placed on hold as incomplete. An applicant may also choose to review the current guidelines for stream restoration in DWQ's Draft Technical Guide for Stream Work in North Carolina, available at http://h2o.enr.state.nc.us/ncwetlands/strm~ide.html. Provide a brief description of the proposed mitigation plan. The description should provide as much information as possible, including, but not limited to: site location (attach directions and/or map, if offsite), affected stream and river basin, type and amount (acreage/linear feet) of mitigation proposed (restoration, enhancement, creation, or preservation), a plan view, preservation mechanism (e.g., deed restrictions, conservation easement, etc.), and a description of the current site conditions and proposed method of construction. Please attach a separate sheet if more space is needed. N/A 2. Mitigation may also be made by payment into the North Carolina Ecosystem Enhancement Program (NCEEP). Please note it is the applicant's responsibility to contact the NCEEP at (919) 715-0476 to determine availability, and written approval from the NCEEP indicating that they are will to accept payment for the mitigation must be attached to this form.

Proposed Impacts on Riparian and Watershed Buffers (required by DWQ) It is the applicant's (or agent's) responsibility to determine, delineate and map all impacts to required state and local buffers associated with the project. The applicant must also provide justification for these impacts in Section VII above. All proposed impacts must be listed herein, and must be clearly identifiable on the accompanying site plan. All buffers must be shown on a map, whether or not impacts are proposed to the buffers. Correspondence from the DWQ Regional Office may be included as appropriate. Photographs may also be included at the applicant's discretion. 1. Will the project impact protected riparian buffers identified within 15A NCAC 2B .0233 (Meuse), 15A NCAC 2B .0259 (Tar-Pamlico), 15A NCAC 02B .0243 (Catawba) 15A NCAC 2B .0250 (Randleman Rules and Water Supply Buffer Requirements), or other (please identify )? Yes ^ No 2. If "yes", identify the square feet and acreage of impact to each zone of the riparian buffers. If buffer mitigation is required calculate the required amount of mitigation by applying the buffer multipliers. Zone* Impact (s uare feet) Multiplier Required Miti ation 1 3 (2 for Catawba) 2 1.5 Total * Zone 1 extends out 30 feet perpendicular from the top of the near bank of channel; Zone 2 extends an additiona120 feet from the edge of Zone 1. 3. If buffer mitigation is required, please discuss what type of mitigation is proposed (i.e., Donation of Property, Riparian Buffer Restoration /Enhancement, or Payment into the Riparian Buffer Restoration Fund). Please attach all appropriate information as identified within 15A NCAC 2B .0242 or .0244, or .0260. N/A XI. Stormwater (required by DWQ) Describe impervious acreage (existing and proposed) versus total acreage on the site. Discuss Stormwater controls proposed in order to protect surface waters and wetlands downstream from the property. If percent impervious surface exceeds 20%, please provide calculations demonstrating total proposed impervious level. Impervious acreage will not change at the proiect site. and other than Martin Walker Road. which is adiacent to the proiect site and is asphalt, impervious surfaces do not exist at the site. Erosion and sedimentation prevention and control will be maintained throughout this project primarily through proper water mana e construction sequencing, proper staging and stockpiling of materials, and through maintenance, at all times, of suitable channel capacity for expected flow events. Equipment, fuels, lubricants, Page 17 of 18 or other potential sources of water pollution will not be stored in areas that could be flooded during this project. XII. Sewage Disposal (required by DWQ) Clearly detail the ultimate treatment methods and disposition (non-discharge or discharge) of wastewater generated from the proposed project, or available capacity of the subject facility.
