Project Description 3a Describe the existing conditions on the site and the general land use in the vicinity of the project at the time of this application Old Fields Creek flows through the three parcels owned by R Vannoy from approximately north to south The site is currently used for cattle pasture /grazing Highway US -221 borders the properties to the west The municipality of West Jefferson, NC is located northeast of the project site The streambanks of Old Fields Creek are eroding due to disconnectivity from the floodplain, upstream stormwater flows from commercial /residential development around West Jefferson, and streambank and riparian vegetation disturbance by cattle which access the stream as a watering source Two un -named tributaries (UT) to Old Fields Creek, referred to as UT1 -OFC and UT2 -OFC enter Old Fields Creek at the project site They are similarly impacted by erosion and cattle access 3b List the total estimated acreage of all existing wetlands on the property 0 3c List the total estimated linear feet of all existing streams (intermittent and perennial) on the property Approximately 690 linear feet of Old Fields Creek, approximately 230 linear feet of UT1 -OFC, approximately 1700 linear feet of UT2 -OFC 3d Explain the purpose of the proposed project Elements included in the project current deflection including i- hooks, toe -wood, and cross -vanes throughout the reaches Natural channel structures will enhance riffle /pool structures and in- stream habitat Streambank and floodplain sloping and benching will re- establish connectivity between the stream and floodplain There will also be a riparian buffer installed along the project reach to help stabilize streambanks and improve water quality The goal is to install natural channel design structures, floodplain benching and sloping, and a forested riparian buffer to restore the stream to reference conditions Cattle will be permanently excluded from the stream via fencing Two (2) stream crossings will be improved and fenced from Old Fields Creek to allow for controlled animal movement between grazing areas 3e Describe the overall project in detail, including the type of equipment to be used The proposed stream restoration will occur along approximately 690 linear feet of Brushy Fork Creek (see Site Plan) Toe wood and ) -hook structures are proposed to be installed along outer river bends Sloping, benching, and pool establishment will occur throughout the reach This restoration also proposes approximately 35 linear feet of restoration along each UT, from each's confluence to 35 ft upstream Following construction, the disturbed areas will be seeded, matted (coconut), and planted with native trees, shrubs, and herbaceous species in all direct riparian areas (see re- vegetation detail) Proposed excavation equipment includes hydraulic thumb trac - hoe(s), and tandem axle road dump truck(s) All heavy equipment will be kept out of the stream channel during project construction except where absolutely necessary to install boulder structures Page 3 of 11 PCN Form — Version 1 3 December 10, 2008 Version 4 Jurisdictional Determinations 4a Have jurisdictional wetland or stream determinations by the Corps or State been requested or obtained for this property / ® Yes El No El Unknown project (including all prior phases) in the past?

Authorized Sienature: Date: ` 4 — — I Mutual Agreement for Stream Restoration Project Resource Institute (RI) is a non-profit organization that assists organizations and individuals in carrying out projects to protect natural and human resources white promoting economic development. RI can assist with projects in a variety of ways, including, but not Iirnited to, fund - raising, administering project fiends, and contracting for services needed to complete a project. RI has recently adopted a project refereed to as the Western North Carolina Stream Initiative to help fainters and landowners address eroding stream banks that are negatively affecting them through loss of property, hazards for livestock, sediment transport into a stream and degraded aquatic habitat. The farmer /landowner has either initiated an application for assistance through USDA/NRCS's EQIP program or has already signed an agreement /contract for assistance with USDA/NRCS's EQIP program. RI's role is to help attain the Rinding, for the design, construction oversight and unmet construction needs of the work for sites with current EQIP program agreements /contracts through USDA/NRCS. RI will assist the farmer /landowner by helping to address issues related to managing and contracting for the required design, planning, permitting and construction work for stream. enhancement practices on the site, as well as necessary structure work, and bank stabilization. RI's objective is to help address current water quality degradation issues; however, work cannot be guaranteed for acts of nature related to flood events. RI is working with NRCS, Conservation Districts and the farmer /landowner to help reduce those impacts as much as possible In providing services to the farnter /landowner on this tract of land for stream restoration/stabilization activities to be performed we thereby .mutually agree to the following items: 1. The farmer /landowner will allow ingress and egress for all activities related to the stream restoration/stabilization such as: surveys, engineering, construction, monitoring, etc. for RI and its agents. 2. Farmer /landowner will follow the contractual guidance in the EQIP program with USD.A., NRCS, 3. Farther /landowner will allow NRCS to provide RI with a copy of the associated NRCS EQIP, application, contract and /or contract modifications, and appendix for the purpose of allowing RI to share with R ' er funders in an effort to help obtain matching dollars. (Initial/date) 4. RI will serve the financial manager for all finds related to the stream restoration /stabilization activities received for the project. 5. RI will provide project management services such as, obtaining the technical resources, bidding and contracting of project elements, and project construction oversight. 6. RI will work with fanners /landowners to resolve differences between construction costs and payment schedule rates Signature Sheet: Stream Restoration Project Agreement Letter ht 6 1 d T--41"r-( C �?J0 4+ County Stream Length Stream Name VAMOV Farmer /landowner Print Name and Title Z F rnxer /landotivner Signature 'lYtl 2- 261-5 Date r V6 tmjv Email Address Phone Number Resource Institute Incorporated Chairman, Resource Institute RC &D, Inc.

ENSURE THE ROOT WADS OF VANE AND SUPPORT LOGS ARE IN GOOD CONTACT WITH EACH OTHER AND THE ROOTS AS INTERLOCKED AS POSSIBLE. 4. SECURE GEOTEXTILE FABRIC TO VANE LOG WITH ROOFING NAILS. 5. CONSTRUCT THE ROCK HOOK BEGINNING FROM THE TOP OF THE VANE LOG. 6. A ROCK CUT OFF SILL WILL THEN BE CONSTRUCTED PERPENDICULAR TO THE ROCK HOOK TO PREVENT THE FORMATION OF A CUTOFF CHANNEL. 7. A TRENCH SHALL BE DUG UPSTREAM ON THE BANKSIDE OF THE WING WHERE NON -WOVEN GEOTE)MLE FABRIC WILL BE PLACED WITH APPROX. 2' OF OVERLAP. ATTACH FABIRC TO VANE LOG WITH ROOFING NAILS. 8.
