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 proposed level spreader bypass channel through the Neuse River Riparian Buffer is needed to construct the proposed structures. 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 Page 5 of 8 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/strm~ide.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 proposed project should not be required to provide mitigation for the proposed impacts. 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/wrp/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): n/a Amount of buffer mitigation requested (square feet): n/a Amount of Riparian wetland mitigation requested (acres): n/a Amount of Non-riparian wetland mitigation requested (acres): n/a Amount of Coastal wetland mitigation requested (acres): n/a IX.

As a result of our meeting conducted on September 20, 2007 with yourself and Lauren Witherspoon, we have outlined the recommended course of action below. Stream clean-up course of action: Since the forested area surrounding the subject stream was in excellent condition, a stream clean-up using volunteer labor and no machinery was proposed. This clean-up day will be conducted on October 13, 2007. Per our discussion, the sediment covering the stream bed will be removed and placed outside of the original wooded floodplain area to prevent future infiltration. En_ inq Bering analysis: Please refer to the attached Pond Details Plan (C2). Mr. Jon Frazier of Crowley, Crisp, & Associates did an excellent job with the concerns that we discussed at our site meeting. To prevent transferring the stormwater from the stormwater pond inlet to the outlet, grip-rap deflection device will be installed between the two structures. This should allow the sediment to concentrate in the modified forebay and result in improved water quality. A 95 linear foot level spreader and bypass device will be placed at the pond outlet structure to achieve diffuse flow. Since a bypass swale is proposed between the stream and level spreader, it is our understanding that this needs to be permitted. We recommend completing aPre-Construction Notification (PCN) to your office this week. Wake Chapel Church NOV Remediation October 3, 2007 Page 2 of 2 Headcut remediation: The incised headcut area below the stormwater pond will also be stabilized. This involves removing a few trees that are barely rooted and adjacent to the void area. Small boulders will be placed at the bottom of the approximately 11-foot deep void. Suitable growing soil will then be placed in the void to the existing adjacent elevation. Geotextile fabric will be used along the existing stream bank to prevent the new soil from entering the stream channel. The North American Green P300, or similar, fabric will also protect the topsoil around the newly planted trees (see below). Riparian plantings: Upon filling the void with suitable soil for the riparian plantings, native trees will be planted at a density consistent with riparian buffer restorations. To achieve the 320 trees per acre at maturity, we propose planting nine (9) trees in the 840 SF (0.02 Ac.) impacted area. Twenty-percent of the trees are required to be 1.5 to 2-inch DBH balled and burlapped. Therefore, two (2) large Tulip Poplars will be planted in the impacted area. The remaining trees will be 3-gallon varieties from the 2001 Guidelines for Riparian Buffer Restoration. The anticipated commencement day of construction is October 15, 2007. This includes modifying the stormwater pond, constructing the level spreader and associated devices, and headcut remediation and plantings. We recommend reconvening with you and Mrs. Witherspoon at the site upon completion. Please let us know at your earliest convenience when this site meeting can be conducted in November. Upon successful remediation, we are requesting written approval of the corrective measures and being in compliance with the violated water quality rules. If you should have questions or require additional clarification during the review please feel free to contact me immediately at (919)844-7437 (office), (919)749-8259 (cell) or email: jay~a kellerenvironmental.com Sincerely, Keller Environmental, LLC 4~ Jay Keller Principal Cc: Jon Frazier, EIT; Crowley, Crisp, & Associates Daryl Algood; Wake Chapel Church Lauren Witherspoon; DWQ Raleigh Regional Office Attachment: Pond Details Plan (C2) at:T-It)-r©OTfWEQ) I~i~39 934~flA tFAx)919t3Z6959~ P O~}~/D02 ~~ ~~~~~ KELI»E~ El~Vl6~c~RtMENT'Al_ SNVtf~C)1VMr"NTAt.
