Included in the package is a revised PCN, a revised SIA (with additional pond information), and additional plan sheets to be added to the package, and an application fee for $240.00 for project impacts of less than an acre and less than 150 linear feet of stream. Per a conversation with Ian Mcmillan I am adding a request for approval on this project of a section 404 permit and 401 water quality certification due to the fact that we are crossing an intermittent stream and impacting the stream channel. Additionally I've included the BMP details and calculations along with a diffuse flow narrative and calculations for stormwater review. Sincerely, Ryan A.

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 ? wetlands installation of Updated 11/112005 n n -r I 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. The proposed stream crossings for the access road and greenway are utilizing existing culvert crossings and are proposed to be improved and widened as necessary to install the access road (impact 1 and the egr enway (Impact 3). The site has a total of 4% impervious and does not require any stormwater BMPs, but we are including two bio-retention ponds for educational purposes. The proposed Greenway (Impact 4 is proposed to be constructed on an existing maintenance road. 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. 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 (see DWQ website for most current version.). 1. 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. Updated 11/1/2005 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://www.nceep.net/pages/inliell eplace.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): 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): IX.
