Impact Justification (Avoidance and Minimization) Specifically describe measures taken to avoid the proposed impacts. It may be useful to provide information related to site constraints such as topography, building ordinances, accessibility, and financial viability of the project. The applicant may attach drawings of alternative, lower-impact site layouts, and explain why these design options were not feasible. Also discuss how impacts were minimized once the desired site plan was developed. If applicable, discuss construction techniques to be followed during construction to reduce impacts. (attached as Appendix A - Avoidance and Minimization) 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. Page 5 of 8 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. 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/strmizide.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. A copy of the EEP Acceptance Letter (April 8, 2008) is attached; this presupposes at 2:1 mitigation ratio throughout the tract. This application requests consideration by USACE and NC-DWQ of a lowered (1:1) ratio for four crossings (A,D,E,F) due to lower aquatic function scores and/or existence of localized pre-existing degradation (Figure 4). Supporting worksheets and photographs are attached as Appendix B and Figures 5 and 6. 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. For additional information regarding the application process for the NCEEP, check the NCEEP website at http://h2o.enr.state.nc.us/wm/index.htm. If use of the NCEEP is proposed, please check the appropriate box on page five and provide the following information: Amount of stream mitigation requested (linear feet): 295 Amount of buffer mitigation requested (square feet): Amount of Riparian wetland mitigation requested (acres): Amount of Non-riparian wetland mitigation requested (acres): Amount of Coastal wetland mitigation requested (acres): Page 6 of 8 IX. Environmental Documentation (required by DWQ) 1. Does the project involve an expenditure of public (federal/state/local) funds or the use of public (federal/state) land? Yes ? No 2.

All residential wastewater will be treated by onsite septic systems in compliance with the Buncombe County Environmental Health Services. XIII. Violations (required by DWQ) Is this site in violation of DWQ Wetland Rules (15A NCAC 2H.0500) or any Buffer Rules? Yes ? No Is this an after-the-fact permit application? Yes ? No XIV. Cumulative Impacts (required by DWQ) Will this project (based on past and reasonably anticipated future impacts) result in additional development, which could impact nearby downstream water quality? Yes ? No If yes, please submit a qualitative or quantitative cumulative impact analysis in accordance with the most recent North Carolina Division of Water Quality policy posted on our website at http://h2o.enr.state.nc.us/ncwetlands. If no, please provide a short narrative description: Immediately downstream of this project, Phoenix Creek is significantly degraded by livestock enclosures which span the stream channel for almost % mile. Any `change-in- use' in this area, which might secondarily result from development of the Client's property, would likely only increase the level of regulatory protection of water quality in this downstream reach. XV. Other Circumstances (Optional): It is the applicant's responsibility to submit the application sufficiently in advance of desired construction dates to allow processing time for these permits. However, an applicant may choose to list constraints associated with construction or sequencing that may impose limits on work schedules (e.g., draw-down schedules for lakes, dates associated with Endangered and Threatened Species, accessibility problems, or other issues outside of the applicant's control).

The initial site design (Figure A-1) as reviewed in the pre-application meeting of January 15) had total of 10 crossings; subsequently, three crossings have been removed by re- routing the road above headwaters and accessing the southwestern quadrant via a `top-down' layout (Figure A-2). The change in road layout in combination with the elimination of a switchback has reduced the total road length by approximately 1700 LF from the original plan. Where possible, the crossings are sited at narrow (e.g. crossings C and G) or locally degraded locations (e.g. crossings A and E). All proposed culverts are oriented to meet the existing thalweg at inlet and outfall with a minimum 20% buried below stream bed. Culverts and riprap are professionally designed and engineered to meet all applicable road and stormwater codes. The Client understands that compliance with all relevant N.C. Division of Land Resources erosion-control requirements will be necessary during road construction. The entrance area of this tract is severely constrained by property and access easement boundaries (Figure 9 - Inset A, Existing Conditions). The existing gravel roadbed is immediately adjacent (Figure A-3, Photos 1-3) to the stream's top-of-bank at several points with resultant erosion and washout problems. Recent re-gravelling of the road surface in combination with placement of sisal baffles on the bank top has temporarily stabilized this area; however these measures do not provide adequate long-term protection to the stream. In one section of the entrance corridor, a meander in the stream requires that the road be shifted outward, away from the stream, to within 1/2 foot of the easement boundary (Figure 10 - Inset A, Proposed Conditions; Figure A-3, Photo 4). To adequately stabilize the bank in this area, it will be necessary to install 65 LF of low retaining wall, placed at 23' to 25' from the stream's top-of- bank. The wall configuration is designed to be the minimum size necessary to provide adequate bank stabilization. The land disturbance from placement of this retaining wall will be temporary and minimal. Given that the total length of the buffer zone within this tract is 4,938 LF, the proposed wall is significantly less (1.3%) than the 10% maximum stipulated in 5A NCAC 0413.0125. All other proposed land disturbances within trout buffers on this tract are road crossings `on, over, or under' watercourses, per G. S. 113A-57 (1). At the request of the Division of Water Quality, a copy of this PCN application has been forwarded to the Division of Land Resources for their review as regards the proposed work and trout buffers on the tract. ?I ENVIRONMENTAL SERVICES, INC. 3661 Alamance Road Burlington, North Carolina 27215 36)570-3002 1923(3)570-9556Fax vn .environmentalservicesinc.com Original Road Layout Phoenix Creek Tract Buncombe County, North Carolina B U R07153.00 Date: December 2007 Drwn/Chkd: csj/vbh Figure: A-1 ? i X D ENVIRONMENTAL Project: BUR07153.00 Final Proposed Road Layout ?
