Project No. 02-7047.01 Honeycutt Creek [03-04-02, 27-20-(2), WS-IV (water supply) NSW (nutrient sensitive)] APPROVAL of 401 Water Quality Certification and AUTHORIZATION CERTIFICATE per the Neuse River Buffer Protection Rules (15A NCAC 2B.0233) with ADDITIONAL CONDITIONS Dear Mr. Fonville: You have our approval, in accordance with the attached conditions and those listed below, to place fill within or otherwise impact 30 feet of streams and 2,233 square feet (ft) of protected riparian buffers for the purpose of constructing the proposed residential subdivision at the subject property, as described within your application dated June 6, 2003. After reviewing your application, we have decided that the impacts are covered by the N.C. Division of Water Quality (DWQ) General Water Quality Certification Number(s) 3404 (GC3404). The Certification(s)allows you to use Nationwide Permit(s) 14 when issued by the US Army Corps of Engineers (USACE): This letter shall also act as your approved Authorization Certificate for impacts to the protected riparian buffers per 15A NCAC 2B .0233. In addition, you should obtain or otherwise comply with any other required federal, state or local permits before you go ahead with your project including (but not limited to) Erosion and Sediment Control, Noh-discharge, and water supply regulations. Also, this approval will expire when the accompanying 404 permit expires unless otherwise specified in the General Certification. This approval is only valid for the purpose and design that you described in your application. If you change your project, you must notify us and you may be required to send us a new application. If the property is sold, the new owner must be given a copy of this Certification and approval letter and is thereby responsible for complying with all conditions. If total fills for this project (now or in the future) exceed one acre of wetland or 150 linear feet of stream, compensatory mitigation may be required as described in 15A NCAC 2H .0506 (h). For this approval to be valid, you must follow the conditions listed in the attached certification and any additional conditions listed below. Conditions: 1. Diffuse Flow An additional condition is that all stormwater shall be directed as diffuse flow at non-erosive velocities through the protected stream buffers and will not re-concentrate before discharging into the stream as identified within 15A NCAC 2B.0233(5). 2. Certificate of Completion Upon completion of all work approved within the 401 Water Quality Certification or applicable Buffer Rules, and any subsequent modifications, the applicant is required to return the attached certificate of completion to the 401/Wetlands Unit, North Carolina Division of Water Quality, 1650 Mail Service Center, Raleigh, NC, 27699-1650.

We also request written concurrence from the North Carolina Division of Water Quality that the project complies with the 401 Water Quality Certifications associated with Nationwide Permit 14 and the Neuse River Basin Buffer Rules. A Pre-construction Notification Application (PCN) is attached as well as an agent authorization form. The proposed project consists of impacts due to the widening of Honeycutt Road (SR 2005). The proposed road widening is needed to provide safe egress and ingress into a proposed residential development (Faircroft Phase III) and is required by the NC-DOT. The project is located on the west side of Honeycutt Road (SR 2005), approximately 2400 feet northwest of the intersection of --- Honeycutt Road-and Durant Road-(SR 2006). The site is=approximately- 32 acres in size and - consists primarily mixed pine/hardwood forests. Please refer to the attached USGS map (Figure 1), which displays the location of the proposed project. S&EC performed a detailed wetland delineation and buffer evaluation on the property on September 20, 2002. Ms. Andrea Wade of the USACE made a site visit to verify our delineation on October 9, 2002, and Ms. Debbie Edwards of the NC-DWQ made a buffer determination on November 4, 2002. A copy of both Ms. Edward's buffer letter, and Ms. Wade's wetland determination is attached. The applicant requested a detailed wetland delineation and buffer evaluation on the property prior to site plan development in order to avoid jurisdictional wetlands and waters and riparian buffers to the maximum extent practicable. The applicant intends to widen Honeycutt Road in order to accommodate a turn lane from the south into Faircroft S/D. The proposed widening will impact Charlotte Office: Greensboro Office: Hicko Office: 236 LePhillip Court, Suite C 3817-E Lawndale Drive 622 Coon Mountain Lane ncord, NC 28025 Greensboro, NC 27455 Taylorsville, NC 28681 (704) 720-9405 Phone: (336) 540-8234 Phone (828) 635-5820 Fax: ,704) 720-9406 Fax: (336) 540-8235 (828) 635 5820 30 linear feet of perennial channel, and 1,409 square feet of Zone 1 and 824 square feet of zone 2 of the Neuse Buffer. Headwalls were used in order to minimize impacts to the stream channel and riparian buffer. These impacts are elaborated upon within the attached PCN form and are shown on the attached inset impact maps. The USACE's_current policy requires applicants to avoid and minimize wetland and stream channel impacts to the maximum extent practicable and may require further compensatory mitigation to offset unavoidable losses of waters of the US when impacts exceed the requirements for notification (0.10 acre). The proposed road widening is needed to provide for access to the proposed subdivision and is required by the NC-DOT. Because the applicant has minimized impacts through the use of headwalls, S&EC believes further compensatory mitigation should not be required by the USACE. NC-DWQ's current policy does not require wetland or stream mitigation for perennial stream channel impacts below 1 acre and 150 linear feet per project. Because the total permanent impacts to perennial channels are less than 150 feet and no wetland impacts are proposed, we believe neither wetland nor stream mitigation should be required by NC-DWO. Please note that according to Withers and Ravenel (project engineer), following construction impervious surface will be less than 15%, therefore, we do not believe that this project requires stormwater treatment. NC-DW-Q? _rrent_policy_does not require riparian buffer mitigation for road crossings that impact less than 1/3 acre and 150 linear feet of buffer per crossing. Although the proposed impacts are below this threshold, we realize that mitigation will be required for parallel impacts to Zone 1 (43 sq. ft.) of the buffer.

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-la outs--and explain -whthese -design options-were-not feasible.--Also discuss how impacts.- were -- - - -minimized-once=the -desired-site-plan was developed: -=lf applicable, -discuss construction - - - techniques to be followed during construction to reduce impacts. The USACE's current policy requires applicants to avoid and minimize wetland and stream channel impacts to the maximum extent practicable and may require further compensatory mitigation to offset unavoidable losses of waters of the US when impacts exceed the requirements for notification (0.10 acre). The proposed existing road widening is needed to provide safe access to the subdivision and is required by the NC-DOT.. Because the applicant has minimized impacts by using headwalls S&EC believes further compensatory mitigation should not be required by the USACE. 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- - - - - - - USAGE --In accordance with--the--Final Notice of Issuance-and-Modification--of--Nationwide --- Permits published in the Federal Register on-March 9, 2000, 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-protectopen waters such as str-eains; and replacing losses of aquatic resource functions and values by creating, restoring, enhancing, or preserving similar functions and values, preferable in the same watershed. Page 5 of 8 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 NCWRP 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.htrnl. 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. 2. Mitigation may also be made by payment into the North Carolina Wetlands Restoration..,- -Program - CWRP . Please note it is the applicant's res onsibili to-contact the NCWRP at - -(919) 733=5208 to -determine availability and-to--request written approval-of-mitigation-prior --- to submittal of a PCN.

Please attach all appropriate information as identified within 15A NCAC 213 .0242 or .0260. Because parallel impacts to Zone 1 of the buffer cannot be avoided we are requesting payment to the NC=WRP `A copy of our `request has been forwarded-to=their office. - XI. Stormwater (required by DWQ) Describe impervious acreage (both existing and proposed) versus total acreage on the site. Discuss stormwater controls proposed in order to protect surface waters and wetlands - ---downstream. from the property.- - Because the percent impervious surface will be less than 15% following construction of the proposed project we do not believe stormwater treatment should be required from DWQ. Page 7 of 8 Downstream water quality will be preserved through the use of level spreaders as well as the preservation of riparian buffer. XII. Sewage Disposal (required by DWQ) - - Clearly detail the ultimate- treatment -methods- and disposition (non-discharge.-or _discharge)_ of wastewater generated from the proposed project, or available capacity of the subject facility.
