May 7, 2010 US Army Corps of Engineers = G , ® sJ Attn: Ms. Tasha McCormick E.A i MAY 1 2r+ 2010 151 Patton Ave Asheville, NC 28801 DENR-WATERMALITY WETLANDS AND STORM KATER (RANCH The purpose of this letter is to request a Nationwide Permit 13 to conduct streambank stabilization on approximately 1,488 linear feet of an unnamed tributary to Little River in Alleghany County, North Carolina. The voluntary stabilization project will be conducted in cooperation with the Natural Resource Conservation Service under the Environmental Quality Incentives Program. The objectives of the conservation plan are to 1) reduce erosion and sedimentation, 2) improve fisheries habitat, and 3) establish riparian buffers. The property was purchased by Maurice and Dolores Woodward in 1981. Failing entrenched stream banks are found through out the reach and a major channel evulsion has occurred at one of the tortuous meanders. The streambanks are unstable and some of the meanders are migrating down the valley as the banks continue to erode. Streambank stabilization will be occurring within a mostly pastured and actively grazed area. A portion of the site has a forested riparian buffer which will be preserved during the course of work. The non-forested areas will be planted with riparian vegetation to establish a proper buffer. Wetlands adjacent to the work area have been delineated and will not be impacted by the proposed activities. The drainage area upstream of the property is mixed forested and grazing/agricultural land. Natural stream design practices were used to determine suitable cross-sectional area, design parameters and structure placement. The implementation of the attached plan will be under the direction of a qualified stream contractor familiar with natural design techniques. The attached plan approximates the locations of the proposed structures and treatment techniques. The final placement of structures will be depicted in an as-built document. The project has the potential to reduce the excessive soil loss derived from the eroding banks. The project is not intended to be a stream restoration project suitable for compensatory mitigation but rather is intended to utilize existing programs and stabilization techniques to improve water quality. The EQIP program has the potential assist many land owners and this is a continued effort to help streamline the program for the future benefit of the environment. The funding under EQIP is limited and there is no compensation for land encumbered under the program. Further, the funding is time-sensitive and a breach of contract is costly. Sparta Office PO Box 1492 Sparta, NC 28675 Sparta, Newton, and Canton, North Carolina We respectfully request an expedited review of the project so that construction can commence by the beginning of June. The funding for the project is time sensitive and a breach of the NRCS contract will result in a monetary penalty. Construction during the low flow periods of the summer is preferable to higher flow periods. Thank you in advance for you consideration.

Streambank instability is resulting in excessively high erosion. Most of the stream work will occur within an open pasture but a small portion of the right streambank looking downstream is a forested area which mil be minimally disturbed. Forested riparian buffers will be established in the field areas as part df this project, Muniflora rose will be managed in the project area, Partial funding is provided by NRCS through EQUIP to reduce soils loss and improve water quality for fisheries. The permitted plan will be reviewed by NRCS prior to implementation. The project intent is to provide the stream with an appropriate bankfull cross-section, stable streembanks and forested riparian buffers. -- 3e- Describe the overall project in detail, including the type of equipment to be used, The attached schematics depict the design concept for the locations of ouctures and grading objectives Typicals are provided for each:: NRCS staff have conducted field inspections of the site. Instream work will be conducted by Backwater Environmental: see attached Backwater statement of qualifications and equipment list. The contractor will maintain all equipment to the highest standard- The contractor will work in the stream where there is danger of removing or harming existing forested buffers and will work from the streambank where there is no forested buffer, The exception being that the equipment must be in the stream to install structures below the bankfull elevation. Streambanks will be mud-ied and matted, Trees will be established within a 25 foot buffer and will be tubed In accordance with NRCS standards; proposed vegetation includes but is not limited to : ache. black walnut, sycamore, will whitet pine. gum. black cherry and willow; all which are commonly found in the region.
