Ross Jr., Secretary North Carolina Department of Environment and Natural Resources r Alan W. Klimek, P.E. Director Division of Water Quality June 2, 2003 DWQ# 03-0576 Guilford County Mr. Roger W. Bardsley Guilford County Planning and Development Department P.O. Box 3427 Greensboro, NC, 27402 APPROVAL of 401 Water Quality Certification with Additional Condition Dear Mr. Bardsley: You have our approval, in accordance with the attached conditions, to place fill in 75 linear feet of perennial streams in order to construct a road crossing associated with the Bicentennial Greenway, Phase IV in Guilford County, as you described in your application received by the Division of Water Quality on May 9, 2003. After reviewing your application, we have decided that this fill is covered by General Water Quality Certification Number 3404, which can be viewed on our web site at httD://h2o.enr.state.nc.us/ncwetlands . This Certification allows you to use Nationwide Permit Number 14 when issued by the Corps of Engineers. In addition, you should get any other federal, state or local permits before you go ahead with your project including (but not limited to) Sediment and Erosion Control, Randleman Buffer Rules, Coastal Stormwater, Non-Discharge and Water Supply Watershed 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 in writing and you may be required to send us a new application for a new certification. If the property is sold, the new owner must be given a copy of the Certification and approval letter and is thereby responsible for complying with all conditions. If total wetland fills for this project (now or in the future) exceed one acre, 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 the additional conditions listed below: 1. The Division of Land Resources' Design Standards in Sensitive Watersheds (15A NCAC 046 .0124) must be adhered to throughout the life of this project; 2. The culverts required for this project shall be installed in such a manner that the original stream profiles are not altered (i.e. the depth of the channel must not be reduced by a widening of the streambed). Existing stream dimensions (including the pattern and profile) are to be maintained above and below locations of each culvert. The culverts shall be designed and installed to allow for aquatic life movement as well as to prevent head cutting of the streams. If any of the existing pipes are or become perched, the appropriate stream grade shall be re-established or, if the pipes installed in a perched manner, the pipes shall be removed and re-installed correctly. The Applicant must submit a plan and receive written approval from this Office to address any head cutting that will occur as a result of this project (e.g., use of cross vanes downstream of the culvert). Use of native vegetation and other soft stream bank stabilization techniques must be used where practicable instead of rip rap or other bank hardening methods; If rip-rap is necessary, it shall not be placed in the stream bed, unless specifically approved by the Division of Water Quality. Upon completion of the project, the Applicant shall complete and return the enclosed "Certificate of Completion" form to notify NCDWQ when all work included in the §401 Certification has been completed. The responsible party shall complete the attached form and return it to the 401 /Wetlands Unit of the NC Division of Water Quality upon completion of the project. Please send photographs upstream and downstream of each culvert site to document correct installation along with the Certificate of Completion form. N. C.

'? ?Opp AEI TySFCT ?4N Please find seven copies of the Pre-Construction Notification Application for the above referenced project. The site is the intended alignment of the Bicentennial Greenway in Greensboro (Figure 1). Guilford County is planning to extend the Bicentennial Greenway from its termination point on Gallimore Dairy Road. The greenway will be constructed along Gallimore Dairy Road and Chimney Rock Road. The greenway will involve road widening and the construction of a sidewalk. The greenway will cross an unnamed tributary to the Deep River. In order to install the greenway, NCDOT requires that Chimney Rock Road be widened. A 72" CMP currently conveys the stream under Chimney Rock Road. To install the sidewalk and widen the road, 16 if of 72" CMP will be added. Due to the angle of the existing crossing, it will be necessary to relocate a short length of the stream channel. In order to minimize the impacts to the stream, a headwall and 2:1 side slopes will be used. The total impact to the stream channel is 75 linear feet. Due to the minimal impact, mitigation is not proposed. On behalf of Guilford County, I am requesting that a 401 Water Quality Certification be issued to authorize this activity.. Please feel free to contact me at (336) 856-7150 if you have any questions concerning this request or if additional information is required.

Pond Creation NA If construction of a pond is proposed, associated wetland and stream impacts should be included above in the wetland and stream impact sections. Also, the proposed pond should be described here and illustrated on any maps included with this application. Pond to be created in (check all that apply): ? uplands ? stream ? wetlands Describe the method of construction (e.g., dam/embankment, excavation, installation of draw-down valve or spillway, etc.): Proposed use or purpose of pond (e.g., livestock watering, irrigation, aesthetic, trout pond, local stormwater requirement, etc.): Size of watershed draining to pond: Expected pond surface area: VII. 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. In order to install the erg enway, NCDOT requires that Chimney Rock Road be widened. A 72" CMP currently pipes the stream under Chimney Rock Road. To install the sidewalk and widen the road, 16 if of 72" CMP will be added. Due to the angle of the existing crossing it will be necessary to relocate a short lens;-th of the stream channel. In order to minimize the impacts to the stream, a headwall and 2:1 side slopes will be used. The total impact to the stream channel is 75 linear feet. 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 Page 5 of 8 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 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 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 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.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 headwall and 2:1 side slopes will be used to limit the impact to the stream to only 75 If. Due to the minimal impact, mitigation should not be required and none is proposed. 2. Mitigation may also be made by payment into the North Carolina Wetlands Restoration Program (NCWRP). Please note it is the applicant's responsibility to contact the NCWRP at (919) 733-5208 to determine availability and to request written approval of mitigation prior to submittal of a PCN. For additional information regarding the application process for the NCWRP, check the NCWRP website at http://h2o.enr.state.nc.us/wr2/index.htm. If use of the NCWRP is proposed, please check the appropriate box on page three 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): Page 6 of 8 IX. Environmental Documentation (required by DWQ) Does the project involve an expenditure of public (federal/state) funds or the use of public (federal/state) land? Yes X No ? If yes, does the project require preparation of an environmental document pursuant to the requirements of the National or North Carolina Environmental Policy Act (NEPA/SEPA)? Note: If you are not sure whether a NEPA/SEPA document is required, call the SEPA coordinator at (919) 733-5083 to review current thresholds for environmental documentation. Yes ? No X If yes, has the document review been finalized by the State Clearinghouse? If so, please attach a copy of the NEPA or SEPA final approval letter. Yes ? No ? X. Proposed Impacts on Riparian and Watershed Buffers (required by DWQ) It is the applicant's (or agent's) responsibility to determine, delineate and map all impacts to required state and local buffers associated with the project. The applicant must also provide justification for these impacts in Section VII above. All proposed impacts must be listed herein, and must be clearly identifiable on the accompanying site plan. All buffers must be shown on a map, whether or not impacts are proposed to the buffers. Correspondence from the DWQ Regional Office may be included as appropriate. Photographs may also be included at the applicant's discretion. Will the project impact protected riparian buffers identified within 15A NCAC 2B .0233 (Meuse), 15A NCAC 2B .0259 (Tar-Pamlico), 15A NCAC 2B .0250 (Randleman Rules and Water Supply Buffer Requirements), or other (please identify )? Yes ? No X If you answered "yes", provide the following information: Identify the square feet and acreage of impact to each zone of the riparian buffers.
