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. The applicant has taken great care in the site design in order to minimize impacts 404 wetlands and streams. However, the tip of two wetland fin eg rs (#1 and #2) will be disturbed by the side slopes of proposed roads. Another wetland area (#3) will be temporarily impacted from the installation of a storm drain. Three stream crossings are needed. Stream impact #1 is needed to tie the subdivision into Clear Run Driye, as required by the County. This crossing is relativel~g_(132 LF) because of the irregular shape of the property boundary in this area and the need to maintain pro ep r road curvature. The applicant will replace two existing culverts (Stream Impacts #2 and #3 , as required by the County. No new impacts are needed at these locations. Updated 11/1/2005 Page9of12 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, available at http://h2o.enr.state.nc.us/ncwetlands/strmgide.html. 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. The applicant proposes to restore 79 LF of stream on site (two areas), preserve all remaining wetlands and streams on site and buy into the EEP for the restoration of 53 LF of stream. 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.

Hamilton, Executive Director MEMORANDUM To: Cyndi Karoly NC DENR/DWQ From: Steven H. Everhart, PhD, CWB Southeastern Permit Coordinator Habitat Conservation Program Date: October 2, 2006 RE: Autumn Hall Town Center, New Hanover County, DWQ # 20060930, USACE Action ID# 200300553 Biologists with the North Carolina Wildlife Resources Commission (NCWRC) have reviewed the subject application for impacts to wildlife and fishery resources. Our comments are provided in accordance with provisions of the Fish and Wildlife Coordination Act (48 Stat. 401, as amended; 16 U.S.C. 661 et. seq.), and Sections 401 and 404 of the Clean Water Act (as amended). The 203.12 acre project site is located south of and adjacent Eastwood Rd. (US 74), between its intersections with Cardinal Dr. and Rogersville Rd. Wilmington. Adjoining properties consist of residential development and undeveloped land. On-site jurisdictional features include streams and forested riparian wetlands totaling 11 acres. The applicant proposes to construct amulti-use development with 281 single-family lots, 33 townhomes, and a town center with offices, retail stores, condominiums, and a hotel. This would impact 0.151 acre of forested wetlands and 2791inear feet of stream by filling/culverting for road access. These impacts would be mitigated through 1) on-site preservation of remaining wetlands, 2) restoration of 79 linear ft of stream, and 3) NC EEP buy-in for 1241inear ft of perennial stream. Mailing Address: Division of Inland Fisheries 1721 Mail Service Center Raleigh, NC 27699-1721 Telephone: (919) 707-0220 Fax: (919) 707-0028 Autumn Hall Town Center 2 October 2, 2006 We have the following concerns/recommendations: We recommend the use of bridges for all stream road crossings and associated wetlands to eliminate the need to fill and culvert, where practicable. If culverts must be used, the culvert should be designed to allow the passage and settlement of aquatic organisms. Generally, this means that the culvert is buried at least one foot below the natural streambed. 2. We recommend a 100 ft native forested buffer be maintained on each side of perennial streams on-site. 3. We recommend utility crossings of streams be made using the directional bore method. 4. We recommend that NC EEP buy-in be made in at least a 2:1 ratio. We recommend that the language preserving remaining wetlands be such that the wetlands are placed in conservation easement that prohibit disturbance of vegetation by any means (cutting, mowing, burning, etc.); modifications of hydrology within the wetlands (ditching, filling, etc.); and soil disturbance. We do not object to the project provided our recommendations are included as permit conditions. Thank you for the opportunity to review and comment on this application.
