Re: Cemetery Branch Sanitary Sewer Replacement Requestfor Buffer Compliance W&R Project Number - 0202o254.i Dear Ms. Chapman: 0 8 0 4 2 5 Q~c~~~d~p MAR 6 2008 DENR - WATErt QUALITY WETLANDS AND STORMWAI'ER BRANCH On behalf of the City of Raleigh we are requesting Buffer Compliance from the NC- DWQfor the impacts to riparian buffers associated with the re-habilitation of a sewer line. Because the proposed stream crossings are less than 40 linear feet and within 15 degrees of perpendicular, we do not believe that 401 Certification is required. The proposed alignment is approximately 510o feet in length and is located adjacent to Cemetery Branch, between Capitol Blvd (SR 401) and North Boundary Street. The project is located in Raleigh, North Carolina (35.8018837°N, 78.6221736°W) and drains into the Neuse River Basin. The WaterQuality Classification for these streams is: C;NSW, the Cataloging Unit forthis site is: 03020201, and the Stream Index number is: 27-33-18-2• Project History Wetlands were delineated by Withers &Ravenel and an upland data form is included with the attachments. On January 18, 2008, apre-application meeting was conducted with Ms. Amy Chapman of the NC-DWQ to review the proposed impacts to the riparian buffers needed to rehabilitate the sewer line. On February 28, 2008, a second meeting was conducted with Ms. Amy Chapman, the City of Raleigh Public Works and Withers & Ravenel to discuss mitigation requirements. Because one component of this project is to protect water quality and move the sewer line away from the creek, it was determined that in area where the existing sewer line is abandoned, the applicant will re-plant the riparian buffer to satisfy mitigation requirements. Project Description/Proposed Impacts This project consists of replacing an aging sewer line that is currently located adjacent to Cemetery Branch Creek. A majority of the existing easement is within 5 feet of the creek and runs parallel on zone 1 and zone 2 of the buffers. In two areas, the existing line is actually runs along the base of the stream. The purpose of this project is to protect water quality by replacing the existing line (i.e. prevent spills) and moving it away from the creek banks wherever possible. The proposed impacts consist of 38 linear feet of important/perennial stream and o.87 acres of riparian iii MacKenan Drive i Cary, NC z75ii i tel: 919.469.3340 i fax: 919.467.6008 i www.withersraveneLcom 7040 Wrightsville Avenue i Suite lol i Wilmington, NC z84o3 i tel: 9io.z56.9z77 i fax: 91o.z56.z584 Brunswick Surveying i loz7 Sabbath Home Rd, SW i Supply, NC z846z i tel: 91o.84z.939z i fax: 91o.84z.8o19 buffer (Zone is 15,572 SF & Zone 2: 22,260 SF) for the installation of this utility line. The impacts are summarized on the overall impact map as well as the PCN form. Avoidance and Minimization Prior to the design process, the applicant requested that detailed wetland delineation be conducted so that impacts to wetlands and `waters' could be minimized. The existing sewer line is located almost exclusively in Zone i and Zone 2 of the buffer or, within the channel of Cemetery Branch. The replacement sewer has been designed to minimize impacts to the riparian buffer and move it farther away from the creek. Approximately 16,298 square feet of line will be abandoned in Zone 1 of the buffer and re-planted with bare root seedlings and 5,885 square feet of Zone 2 will be abandoned and re-seeded with fescue. However, due to existing houses and structures, the sewer line could not be located entirely outside of the 50- foot buffer. Whenever possible, the work will be confined to the previously disturbed areas in Zone 2. Mitigation The NC-DWQ has determined that re-planting the buffers in the abandoned sewer easement will satisfy mitigation requirements. The applicant will plant bare root seedlings at a density sufficient to provide 320 trees per acre at maturity. To achieve this density, approximately 4.36 (10x10 feet spacing) to 681(8x8 feet spacing) trees per acre will be planted. Depending on what is available at the time of planning, the applicant will provide at least 3 different tree species native to this area.

Describe the existing conditions on the site and general land use in the vicinity of the project at the time of this application: Approximately half of the project will be confined to an existing sewer easement. The land use within the vicinity of the project consists of residential yards, and roads/parking lots. 10. Describe the overall project in detail, including the type of equipment to be used: This project consists of replacin an aging sewer line that is currently located adjacent to Cemetery Branch Creek. A majority of the existing easement is within 5 feet of the creek and runs parallel on zone 1 and zone 2 of the buffers. In two areas the existin lig_'ne is Page 2 of 8 actually runs along the base of the stream. Large excavating equipment (i.e. trackhoe) will be used to install the sewer line. 11. Explain the purpose of the proposed work: The purpose of this project is to protect water quality by replacing the existin lg ine (i.e. prevent spills) and moving it away from the creek banks wherever possible. The current line constructed of clay pipe with joints every 3 feet will be replaced by a metal pipe with fewer joints, reducing the risk of spills and extending the life of the sewer line. IV. Prior Project History If jurisdictional determinations and/or permits have been requested and/or obtained for this project (including all prior phases of the same subdivision) in the past, please explain. Include the USACE Action ID Number, DWQ Project Number, application date, and date permits and certifications were issued or withdrawn. Provide photocopies of previously issued permits, certifications or other useful information.

If this is a NCDOT project, list and describe permits issued for prior segments of the same T.I.P. project, along with construction schedules. Wetlands were delineated b~Withers &Ravenel and an upland data form is included with the attachments. On January 18 2008 apre-application meeting was conducted with Ms. Amv Chapman of the NC-DWO to review the proposed impacts to the riparian buffers needed to rehabilitate the sewer line. On February 28 2008 a second meeting was conducted with Ms. Amv Chapman and members of the City of Raleigh Public Works and Withers &Ravenel to discuss mitigation requirements. Because one comRonent of this project is to protect water quality and move the sewer line away from the creek it was determined that in area where the existing sewer line is abandoned the applicant will re-plant the riparian buffer to satis mitigation requirements. V. Future Project Plans Are any future permit requests anticipated for this project? If so, describe the anticipated work, and provide justification for the exclusion of this work from the current application. No additional impacts are proposed at this time. VI. Proposed Impacts to Waters of the United States/Waters of the State It is the applicant's (or agent's) responsibility to determine, delineate and map all impacts to wetlands, open water, and stream channels associated with the project. Each impact must be listed separately in the tables below (e.g., culvert installation should be listed separately from riprap dissipater pads). Be sure to indicate if an impact is temporary. All proposed impacts, permanent and temporary, must be listed, and must be labeled and clearly identifiable on an accompanying site plan. All wetlands and waters, and all streams (intermittent and perennial) should be shown on a delineation map, whether or not impacts are proposed to these systems. Wetland and stream evaluation and delineation forms should be included as appropriate. Photographs may be included at the applicant's discretion.

Isolated Waters Do any isolated waters exist on the property? ^ Yes ®No Describe all impacts to isolated waters, and include the type of water (wetland or stream) and the size of the proposed impact (acres or linear feet). Please note that this section only applies to waters that have specifically been determined to be isolated by the USACE. 8. Pond Creation 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.): NA Proposed use or purpose of pond (e.g., livestock watering, irrigation, aesthetic, trout pond, local stormwater requirement, etc.): NA Current land use in the vicinity of the pond: NA Size of watershed draining to pond: NA Expected pond surface area: NA 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. Prior to the design process, the applicant requested that detailed wetland delineation be conducted so that impacts to wetlands and `waters' could be minimized. The existing sewer line is located almost exclusively in Zone 1 and Zone 2 of the buffer or within the channel of Cemetery Branch 'The replacement sewer has been designed to minimize impacts to the riparian buffer and move it farther away from the creek. Approximately 16,298 square feet of line will be abandoned in Zone 1 of the buffer and re-planted with bare root seedlings and 5,885 of Zone 2 will be abandoned and re-seeded with fescue. However, due to existing houses and structures the sewer line could not be located entirely outside of the 50-foot buffer. Whenever possible the work will be confined to the previously disturbed areas in Zone 2. VIII. Mitigation DWQ - In accordance with I SA 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. Page S of 8 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. Because the stream impacts are temporary and will be returned to pre-construction contours the applicant does not propose mitigation for the stream crossing. Approximately 16 298 square feet of line will be abandoned in Zone 1 of the buffer and re-planted with bare root seedlings and 5,885 square feet of Zone 2 will be abandoned and re-seeded with fescue to satis mitigation requirements. 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): NA Amount of buffer mitigation requested (square feet): NA (see below) Amount of Riparian wetland mitigation requested (acres): NA Amount ofNon-riparian wetland mitigation requested (acres): NA Amount of Coastal wetland mitigation requested (acres): NA Page 6 of 8 IX.

Cumulative Impacts (required by DWQ) Will this project (based on past and reasonably anticipated future impacts) result in additional development, which could impact nearby downstream water quality? Yes ^ No If yes, please submit a qualitative or quantitative cumulative impact analysis in accordance with the most recent North Carolina Division of Water Quality policy posted on our website at http://h2o.etu-.state.nc.us/ncwetlands. If no, please provide a short narrative description: This protect involves the replacement of an existing sewer line The surrounding areas are established neighborhoods; therefore, we do not believe that this project will have a negative impact on downstream water quality. XV, Other Circumstances (Optional): It is the applicant's responsibility to submit the application sufficiently in advance of desired construction dates to allow processing time for these permits. However, an applicant may choose to list constraints associated with construction or sequencing that may impose limits on work schedules (e.g., draw-down schedules for lakes, dates associated with Endangered and Threatened Species, accessibility problems, or other issues outside of the applicant's control). /~ ~~ ~., Applicant/Agent's Signature Date (Agent's signature is valid only if an authorization letter from the applicant is provided.) ~ Page 8 of 8 ,~ j ~-- - ' ~ ,~ ~' - ~ '-i .}• ~, ~r J ana~!`J 1 . t3ore, o ~~ N ~ - ~' ~ ~ V ~y i ` Y ~ s . ti ~ i ~ •. 1 j~sv !
