Division of Water Quality (DWQ) on January 21, 2005 and all additional information submitted and received on March 11, 2005, and May 19, 2005. After reviewing your application, we have decided that the impacts are covered by General Water Quality Certification Number(s) 3402 (GC3402). The Certification(s) allows you to use Nationwide Permit(s) 39 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, and Non-discharge regulations. Also, this approval to proceed with your proposed impacts or to conduct impacts to waters as depicted in your application shall expire upon expiration of the 404 or CAMA Permit. This approval is 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). This approval requires you to follow the conditions listed in the attached certification and any additional conditions listed below. The Additional Conditions of the Certification are: 1.

Project Information Attach a vicinity map clearly showing the location of the property with respect to local landmarks such as towns, rivers, and roads. Also provide a detailed site plan showing property boundaries and development plans in relation to surrounding properties. Both the vicinity map and site plan must include a scale and north arrow. The specific footprints of all buildings, impervious surfaces, or other facilities must be included. If possible, the maps and plans should include the appropriate USGS Topographic Quad Map and NRCS Soil Survey with the property boundaries outlined. Plan drawings, or other maps may be included at the applicant's discretion, so long as the property is clearly defined. For administrative and distribution purposes, the USACE requires information to be submitted on sheets no larger than 11 by 17-inch format; however, DWQ may accept paperwork of any size. DWQ prefers full-size construction drawings rather than a sequential sheet version of the full-size plans. If full-size plans are reduced to a small scale such that the final version is illegible, the applicant will be informed that the project has been placed on hold until decipherable maps are provided. 1. Name of project: Meadowood Subdivision 2. T.I.P. Project Number or State Project Number (NCDOT Only): 3. Property Identification Number (Tax PIN): 0771769539, 0771675572 4. Location County: Wake Nearest Town: Cary Subdivision name (include phase/lot number): Meadowood Subdivision Directions to site (include road numbers, landmarks, etc.): The site is located approximately 2000 feet southeast of the intersection of Campbell Road (SR 1383) and Holly Springs Road (SR 1152) in Wake County, NC. 5. Site coordinates, if available (UTM or Lat/Long): 035043'1 1.37"N/078044'38.61 "W (Note - If project is linear, such as a road or utility line, attach a sheet that separately lists the coordinates for each crossing of a distinct waterbody.) 6. Property size (acres): ± 126 acres 7. Nearest body of water (stream/river/sound/ocean/lake): Swift Creek 8. River Basin: Neuse (Note - this must be one of North Carolina's seventeen designated major river basins. The River Basin map is available at http://h2o.enr.state.nc.us/admin/maps/.) 9. Describe the existing conditions on the site and general land use in the vicinity of the project at the time of this application: The site is currently wooded. Portions of the site that were formally cultivated fields are in primary to secondary successional stages. Page 2 of 8 10. Describe the overall project in detail, including the type of equipment to be used: The proposed project is a single-family residential subdivision with the typical utilities (i.e., sewer, water, electric, etc.). Wetlands, a perennial stream, an intermittent stream, and their associated riparian buffers will be impacted to provide a road to connect to the eastern end of the proposed Meadowood Subdivision. Typical excavatingy and grading equipment will be used during construction activities. 11. Explain the purpose of the proposed work: The purpose for this subdivision is to provide additional housing for the area. The road crossings of the perennial and intermittent stream are required to connect to the eastern end of this property. The road location is dictated by the existence of an existing road stub on an adiacent property. Both streams transverse the entire property which make impacts unavoidable. 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. Describe previously approved wetland, stream and buffer impacts, along with associated mitigation (where applicable). 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. No previous 401/404 permits have been issued for this site. Mr. Mike Horan of the NC-DWQ has visited the site to make buffer calls. During well drilling activities the two stream channels were crossed and impacted. Both of these crossings are less than 40 linear feet each and proposed subdivision roads have been designed so as to cross in these locations and not result in additional impacts. The wetlands and streams on the property have been flagged by S&EC. 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 permits are anticipated 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. The applicant must also provide justification for these impacts in Section VII below. All proposed impacts, permanent and temporary, must be listed herein, and must be clearly identifiable on an accompanying site plan. All wetlands and waters, and all streams (intermittent and perennial) must 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. If this proposed impact is strictly for wetland or stream Page 3 of 8 mitigation, list and describe the impact in Section VIII below. If additional space is needed for listing or description, please attach a separate sheet. 1. Provide a written description of the proposed impacts: Two buffered stream channels will be impacted by roads within the proposed subdivision. Proposed permanent stream channel impacts include 119 linear feet of perennial channel and 65 linear feet of intermittent channel. Wetlands impacted on site include 0.2539 acre due to the construction of required roads. 2. Individually list wetland impacts below: Wetland Impact Site Number (indicate on ma) Type of Impact* Area of Impact (acres) Located within 100-year Floodplain** (es/no) Distance to Nearest Stream (linear feet) Type of Wetland*** 1 fill 0.0331 no +/_100 emergent 2 fill 0.1074 no 0 emergent 3 fill 0.0429 no 600' emergent 4 fill 0.0038 no 150' emergent 5 Fill 0.0384 No +/-120 Headwater wetland 6 fill 0.0282 No +/-200 Emergent * List each impact separately and identify temporary impacts. Impacts include, but are not limited to: mechanized clearing, grading, fill, excavation, flooding, ditching/drainage, etc. For dams, separately list impacts due to both structure and flooding. ** 100-Year floodplains are identified through the Federal Emergency Management Agency's (FEMA) Flood Insurance Rate Maps (FIRM), or FEMA-approved local floodplain maps. Maps are available through the FEMA Map Service Center at 1-800-358-9616, or online at httn://www.fema.gov. *** List a wetland type that best describes wetland to be impacted (e.g., freshwater/saltwater marsh, forested wetland, beaver pond, Carolina Bay, bog, etc.) Indicate if wetland is isolated (determination of isolation to be made by USACE only). List the total acreage (estimated) of all existing wetlands on the property: +/- 5 acres Total area of wetland impact proposed: 0.2538 acre 3. Individually list all intermittent and perennial stream impacts below: Stream Impact Length of Average Width Perennial or Site Number Type of Impact* Impact Stream Name** of Stream Intermittent? (indicate on ma) (linear feet) Before Impact (please secif ) 1 Culvert/fill 119 UT to Swift Creek 9-10' perennial 2 Culvert/fill 65 UT to Swift Creek 3' intermittent * List each impact separately and identify temporary impacts. Impacts include, but are not limited to: culverts and associated rip-rap, dams (separately list impacts due to both structure and flooding), relocation (include linear feet before and after, and net loss/gain), stabilization activities (cement wall, rip-rap, crib wall, gabions, etc.), excavation, ditching/straightening, etc. If stream relocation is proposed, plans and profiles showing the linear footprint for both the original and relocated streams must be included. ** Stream names can be found on USGS topographic maps. If a stream has no name, list as UT (unnamed tributary) to the nearest downstream named stream into which it flows. USGS maps are available through the USGS at 1-800-358-9616, or online at www.usgs.gov. Several intcmct sites also allow direct download and printing of USGS maps (e.g., www.topozonacom, www.mapguest.coin, etc.). Cumulative impacts (linear distance in feet) to all streams on site: 184 linear feet Page 4 of 8 4. Individually list all open water impacts (including lakes, ponds, estuaries, sounds, Atlantic Ocean and any other water of the U.S.) below: Open Water Impact Area of Name Waterbody Type of Waterbody Site Number Type of Impact* Impact ) (if applicable) (lake, pond, estuary, sound, indicate on ma (acres) bay, ocean, etc.) N/A N/A N/A N/A N/A * List each impact separately and identify temporary impacts. Impacts include, but are not limited to: fill, excavation, dredging, flooding, drainage, bulkheads, etc. 5. 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.): N/A Proposed use or purpose of pond (e.g., livestock watering, irrigation, aesthetic, trout pond, local stormwater requirement, etc.): N/A Size of watershed draining to pond: N/A Expected pond surface area: N/A 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. The client requested a detailed delineation to minimize and avoid impacts to iurisdictional waters (including wetlands) to the maximum extent possible. Due to the nature of the property, the two stream crossings are necessary to access the eastern portion of the property. These crossings were planned for the areas previously impacted during well-drilling activities. These proposed crossings are at a nearly perpendicular angle to minimize impacts to the stream channel and were placed in the location of the previous drill rig crossings. The road resulting in Impact 3 was redesigned to avoid unnecessary impacts to the wetlands and the buffered stream. 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. Page 5 of 8 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://l12o.enr.state.ne.us/ncwetlands/stnngide.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 applicant has avoided and minimized stream channel impacts by crossing stream channels in a perpendicular fashion and the proposed impacts to perennial/important streams are less than 150 linear feet no stream mitigation is proposed. If mitigation is required, however,the applicant proposes payment to the EEP. 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.ne.us/wrp/index.litm. 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): 0 Amount of buffer mitigation requested (square feet): 0 Amount of Riparian wetland mitigation requested (acres): 0.25 Amount of Non-riparian wetland mitigation requested (acres): 0 Amount of Coastal wetland mitigation requested (acres): o 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 ? 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 ? 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 213 .0233 (Meuse), 15A NCAC 2B .0259 (Tar-Pamlico), 15A NCAC 213 .0250 (Randleman Rules and Water Supply Buffer Requirements), or other (please identify Yes ® No ? If you answered "yes", provide the following information: Identify the square feet and acreage of impact to each zone of the riparian buffers. If buffer mitigation is required calculate the required amount of mitigation by applying the buffer multipliers. Crossinn 1 (Perennial Stream) Zone* Impact (square feet) Multiplier Required Mitigation 1 9,776 3 N/A 2 4,415 1.5 N/A Total 14,191 N/A Crossing 2 (Intermittent Stream) Zone* Impact (square feet) Multiplier Required Mitigation 1 3,348 3 N/A 2 5,245 1.5 N/A Total 8,593 N/A Page 7 of 8 * Zone I extends out 30 feet perpendicular from near bank of channel; Zone 2 extends an additional 20 feet from the edge of Zone 1. If buffer mitigation is required, please discuss what type of mitigation is proposed (i.e., Donation of Property, Conservation Easement, Riparian Buffer Restoration / Enhancement, Preservation or Payment into the Riparian Buffer Restoration Fund). Please attach all appropriate information as identified within 15A NCAC 213 .0242 or .0260. Because both crossings will impact less than 1/3 acre of riparian buffer the proposed activity is considered "Allowable" and therefore will not require buffer mitigation. 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. The proposed project will have less than 12% impervious coverage and will therefore not require a DWQ approved stormwater plan, however the diffuse flow measures will be met and the required worksheets have been submitted.

The original Pre- construction Notification (PCN) application was received by the Division of Water Quality (DWQ) on January 21, 2005. The requests listed by your office are below and are followed by our responses. The additional information provided below should be considered as appendices and revisions to the January 21, 2005 application. Additional Information: 1. In the response letter, it was indicated that there world be an energy dissipater at crossing #1 and at Crossing #2. Crossing #1 is being constructed on a large watershed, please submit the velocities of water that will be flowing through this crossing post-construction and the slope in which the culverts will be placed. Energy dissipaters are not being proposed for either Crossing 1 or 2. Bank Stabilization is proposed for the downstream side of Crossing 1 (see attached map). As per the engineers calculations Crossing 1 will have a post construction velocity of V25 = 8.51 fps and Vloo = 9.85 fps. Crossing 2 has a post construction velocity of V25 = 4.37 fps and V loo = 4.89 fps. The Engineer believes that because the main culvert will be buried and in Charlotte Office: 236 LePhillip Court, Suite C Concord, NC 28025 Phone: (704) 720-9405 Fax: (704) 720-9406 Greensboro Office: 3817-E Lawndale Drive Greensboro, NC 27455 Phone: (336) 540-8234 Fax: (336) 540-8235 Meadowood Subdivision S&EC Project #8386.W2 May 19, 2005 Page 2 of 3 an effort to avoid additional impacts, bank stabilization is a more appropriate measure rather than an energy dissipater. This stabilization will require additional buffer impacts but will not require additional stream impacts. Please note that the centerline of the stream of crossing 1 is shown and that the buffers are extended from the top-of-bank. The dashed lines running parallel to the centerline is the "drainage easement" not the edge of the channel. The channel width in this area is 10 feet. At the location of Impact 1 the limits of disturbance from the road/wing wall installation have been reduced however the overall buffer impact at this crossing has increased due to the proposed placement of rip-rap bank stabilization (not to be installed in the stream or below the water line). The buffer impacts for-Impact 1 will total 0.32 acre. Please see the impact chart on the attached inset of Impact 1. 2. Fill is being proposed for impacts 3, 4, and 5, in order for the hydrology to not be discontinued a culvert will be needed at impacts 4 and S, please submit impact maps showing culverts for hydraulic connectivity. The proposed pipes have been realigned and positioned in the natural drainage in impact areas 3, 4, and 5. This will make sure that the natural drainages are not hydraulically bypassed. 3. Nutrient removal efficiencies for grassed swales are only 20%, therefore you cannot directly discharge this stormwater into a buffered streant, level spreaders are required outside of the riparian buffers. In addition, the stormwater management plan that is being proposed (diffuse flow provisions only) do not require extensive planning or design so a conditional approval will not be given for this project. Please design level spreaders at all easements (not plunge pools) that are being directed to riparian buffers and submit the level spreader worksheets for each. (Please note: easements are needed around all stormwater BMP's for maintenance purposes, please include a new site plan that includes all level spreaders). Level spreaders have been proposed and designed for all locations where possible. Scour holes are proposed in other locations where the drainage area acts as a constraint on the level spreader lengths. The project will not be using curb and gutter but will have earthen/grassed ditches. Grassed swales that meet DWQ standards will also be used in all feasible locations. Because Zone 2 will be grassed in the areas of the proposed level spreaders these level spreaders where sized using the 13 linear foot per 1 acre of drainage guidelines.

Grassed Swales & Other Questions Subject: Grassed Swales & Other Questions From: "Bob Zarzecki" <bzarzecki@sandec.com> Date: Wed, 20 Apr 2005 10:39:56 -0400 To: "Debbie Edwards \(DWQ\)" <debbie.edwards@ncmail.net>, "Cyndi Karoly \(DWQ\)" <cyndi.karoly@ncmai1.net>, "John Hennessy \(DWQ\)" <john.hennessy@ncmail.net> CC: "Torn Reeder \(DWQ\)" <torn.reed er@ncmai.net>, "Sean Clark" <sclark@sandec.com> Cyndi, Debbie & John H., Sean received a request for additional information for Meadowood (DWQ 05-0101). He asked me to take a look at the letter. I have a few questions. 1. Question 1 asks about the velocities of water that will be flowing through the pipe, slope of the pipe and seems to be inferring that a rock energy dissipater below Crossing #1 should be used. The engineer is proposing to use two 84" pipes. One will be aligned with the 5 to 6 foot wide stream and buried 1 foot. The other will be raised. This design will ensure that the normal, low flows will pass through the pipe aligned with the stream and higher flows (above bankfull) will flow through the raised pipe. The use of a dissipater will increase impacts to the perennial stream. Also, I typically recommend that engineers avoid dissipaters if at all possible (it depends on what DOT, Land Quality or the local municipalities will allow) to aid in the compliance with the certification conditions of aquatic life passage and channel stability. I'm not an engineer, but I think that it is reasonable to assume that velocities through twin 84" pipes on a 600+ acre watershed will not be an issue for channel stability. The slope of the pipe can be taken from the cross sections provided in the last package of additional infornation. It's approximately a 6" drop over 100 feet or a slope of 0.005. If you still want the velocities, then we will need to know what storni events and discharges that you would like us to use. Please advise. 2. Impacts 4 & 5 have culverts just not at the location of the wetlands. Basically, what would have occurred would be a diversion of the overland flow into the road side ditches, through the culverts, into the road side ditch along the other side of the road and back to the wetland below the road. The overland flow would not have been diverted away from the downstream wetlands. Other sources of hydrology (subsurface flow, groundwater, rain water, etc.) would most likely not be effected by this design. We'll discuss relocating the culverts to align with the wetlands with the engineer, but I don' think that the current design would have significantly discontinued the hydrology of the wetlands. 3. The Big Question: Is DWQ no longer accepting the sole use of grassed swales as stormwater management facilities that remove nitrogen to allow for stormwater conveyances through the buffer? If so, what has DOT been proposing in similar situations where diffuse flow can not be achieved? The second part of this question states that, "the stormmater management plan that is being proposed (diffuse low provisions only) do not require extensive planning or design so a conditional approval will not be given for this project". This is the first that I have heard this statement used. Is DWQ no longer approving projects with the diffuse flow review conditions? As of the date that our information was submitted, it was my understanding that you were? Most of the issues raised above have not been issues on previously approved projects. This is a large lot subdivision (average lot sizes around 1 acre), proposing less than 12% built upon area, no curb and gutter and what I think is a reasonable request for impacts. The only real issue that I see is diffuse flow. It will be difficult to achieve this in some locations. That is why grassed swales have been proposed. The diffuse flow provision is a performance based requirement. The engineer believes that the current design will comply with the requirement, with the exception of the direct discharge /grassed Swale locations. In the pastas long as the general concepts seems reasonable, the 401s have been approved and Todd worked out the diffuse flow issues later. If that is no longer going to be the case, then please let us know and we'll advise our clients that we'll need stormwater management plans prior to submitting the PCN for all future developments. (One thing that bugs me about this one is that I've seen other approvals issued for projects with much higher percentages of BUA and little to no stormwater management plans.) Please advise us on the issues discussed above. Sean is still the project manager for this project. I'll discuss your responses to the questions above with him and we'll do our best to relay your concerns to the engineer. 1 of 2 4/20/2005 11:27 AM N1ATF9Q Michael F. Easley, Governor William G.

Therefore, unless we receive the additional information requested below, we will have to move toward denial of your application as required by 15A NCAC 2H .0506 and will place this project on hold as incomplete until we receive this additional information. Please provide the following information so that we may continue to review your project. Additional Information Requested: 1. In the response letter, it was indicated that there would not bean energy dissipater at crossing #1 and at crossing #2. Crossing #1 is being constructed on a large watershed, please submit the velocities of water that will be flowing through this crossing post-construction and the slope in which the culverts will be placed. 2. Fill is being proposed for impacts 3, 4 and 5, in order for the hydrology to not be discontinued a culvert will be needed at impacts 4 and 5, please submit impact maps showing culverts for hydraulic connectivity. 3. Nutrient removal efficiencies for grassed swales are only 20%, therefore you cannot directly discharge this stormwater into a buffered stream, level spreaders are required outside of the riparian buffers. In addition, the stormwater management plan that is being proposed (diffuse flow provisions only) do not require extensive planning or design so a conditional approval will not be given for this project. Please design level spreaders at all drainage easements (not plunge pools) that are being directed to riparian buffers and submit the level spreader worksheets for each. (Please note: easements are needed around all stormwater BMP's for maintenance purposes, please include on new site plan that includes all level spreaders.) 401 Oversight/Express Review Permits Unit 1650 Mail Service Center, Raleigh, North Carolina 27699.1650 2321 Crabtree Boulevard, Suite 250, Raleigh, North Carolina 27604 Phone: 919-733-1786 / FAX 919-733.6893 / Internet: htto://h2o.enr.state.nc.us/ncwetiands one N Carolina ,?timrillif An Equal Opportunity/Affirmative Action Employer - 50% Recycled/10% Post Consumer Paper Over the Meadow, LLC Page 2 of 2 April 11, 2005 Please respond within three weeks of the date of this letter by sending this information to me in writing and Eric Kulz of the DWQ Raleigh Regional Office.

The original Pre-construction Notification (PCN) application was received by the Division of Water Quality (DWQ) on January 21, 2005. The requests listed by your office are below and are followed by our responses. The additional information provided below should be considered as appendices and revisions to the January 21, 2005 application. Additional Information: 1. Site Plan Details a. You have provided inipact maps in sets showing the proposed buffer impacts for crossings I and 2. Please provide details of the impacts including but not limited to culverts, dissipaters, headwalls eta and at a scale of I "=50 The engineer has provided sketch maps (see Figures 1 & 2) depicting the extent of the fill slopes required for the construction of the roads within the location of the stream crossings. Pending your approval, these designs and limits of disturbance will be incorporated within the final construction drawings. Charlotte Officer Greensboro Office: 236 LePhillip Court, Suite C 3817-E Lawndale Drive Concord, NC 28025 Greensboro, NC 27455 Phone: (704) 720-9405 Phone:, (336) 540-8234 Fax: (704) 720-9406 Fax: (336) 540-8235 Meadowood Subdivision S&EC Project #8386.W2 March 11, 2005 Page 2 of 5 Crossing 1 (see Figure 1) - A steep slope exists on the west side of the stream in the location of the proposed crossing. This will require the fill slopes to extend outside of the right of way. The updated designs have resulted in changes to the impacts proposed within the original application. The revised impacts have been provided in the attached Revised Impact Table (see Appendix 1). To further reduce stream impacts, head walls will be used and are depicted on the attached sketch. Proposed channel impacts have been reduced from 130 feet to 119 feet. Dissipaters will not be used. Please note that the total impacts to Neuse River Buffers proposed for Crossing 1 equal 0.325 acres. We understand that the total buffer impacts approved for this crossing may not exceed 0.325 acres and that buffer mitigation will be required for this crossing if the impacts exceed 1/3 acre. The final construction plans for this crossing will ensure that the buffer impacts do not exceed 0.325 acres. Crossing 2 (see Figure 2) - The engineer has depicted the extent of the fill slopes. The slopes will need to extend slightly outside of the proposed right of way. The updated designs have resulted in changes to the impacts proposed within the original application. The revised impacts have been provided in the attached Revised Impact Table (see Appendix 1). By utilizing headwalls, proposed channel impacts have been reduced from 115 feet to 65 feet. Impact 3 (see Figure 3) - Wetland impacts proposed for the construction of the intersection of Street I & H have been modified from the original PCN and are included in the attached Revised Impact Table (see Appendix 1). Impacts 4 & 5 (see Figure 4) - Wetland impacts proposed for the construction of the intersection of Street J (previous impact 4) and Street I (previous impact 5) have been modified from the original PCN and are included in the attached Revised Impact Table (see Appendix 1). b. You have road crossings I and 2, and several "20 feet drainage easements" along both streams to be impacted Please provide provisions for diffuse flow. If level spreaders are to be proposed, provide . the level spreader worksheets that can be found on our fveb site. The engineer has provided a conceptual stormwater management plan and worksheets (see Appendix 2) to address how this project will comply with Meadowood Subdivision S&EC Project #8386.`'V2 March 11, 2005 Page 3 of 5 the diffuse flow provision of the Neuse Buffer Rule. Please note that this conceptual plan includes the use of grass swales in many locations where diffuse flow will also be provided. However, there are two locations where diffuse flow will not be provided. These include the discharges between lots 11 & 12 and between lots 30 & 31. Additional buffer impacts will be required at these two locations. The conceptual design calls for continuing the grass swales through the buffer and discharging directly into the stream. Rip-rap protection / dissipaters may be required within the swale just prior to entering the stream to prevent erosive velocities. The grass swales will be designed as per the N.C. DENR Stormwater BMP Manual and should be considered as stormwater management facilities that control nitrogen. The swales will have side slopes of 3:1 or flatter and will be at least 100 feet long for every acre of drainage to them. These direct discharges are required due to steep slopes within the buffer. We request that if you require additional information regarding this conceptual stormwater management plan, that you issue a conditional approval including the "Diffuse Flow - DWQ Review Required" standard condition that you have required for other low density development projects similar to this one. G Please contact Eric Kulz at the Raleigh Regional Office to conftrrrt existing impacts and to stake an intermittent/perennial stream determination on stream B. Mr. Mike Horan of the Raleigh Regional Office has already been to the site to determine the applicability of the Neuse Buffer Rules. We have contacted Mr. Horan and lie has informed us that there is no need to revisit the site to determine whether this stream is intermittent or perennial as it pertains to the mitigation requirements of General Water Quality Condition No. 3402 (GC3402). Mr. Horan has determined based on his previous site visit that this stream is "intermittent" and should not require stream mitigation under GC3402. Please contact Mr. Horan if you have any additional questions regarding his determination. d In set map 1 shows the proposed street A impacting a wetland 'These impacts are not included ivith your application. Please revise the PCN to include these proposed impacts. Meadowood Subdivision S&EC.Project #8386.W2 March 11, 2005 . Page 4 of 5 The engineer has provided details (see Figure 1) of the proposed wetland impact required for the construction of Street A. These wetland impacts have been included within the attached Revised Impact Table (see Appendix 1). e. Please provide the total built-out percent impervious proposed for the recreation area. The recreation area is only proposed to contain playground equipment, park benches, picnic tables, etc. and is not anticipated to exceed 12% impervious cover. The subdivision is a low-density development with grass roadside swales (not curb and gutter), with an average lot size of 0.89 acres for Phase 1 and 1.08 acres for Phase 2. Also, there will be over 35 acres of open space. The total site will contain less than 12% built upon area or impervious cover. (This information is described in detail within the attached conceptual stormwater management plan.) f. Please provide cross section details showing the provisions for aquatic life passage. Crossing 1 (see Figure 5A & 513) - The engineer has provided cross section details for this crossing. Two 84" pipes are proposed for this crossing. The pipes will be aligned with the stream such that the low flows utilize only one of the two 84" pipes. The primary pipe will be buried one foot below the bed of the stream to allow for the passage of aquatic life. Crossing 2 (see Figure 6A & 613) - The engineer has provided cross section details for this crossing. Two 48" pipes are proposed for this crossing. The pipes will be aligned with the stream such that the low flows utilize only one of the two 48" pipes. Although the stream is intermittent, the primary pipe will be buried accordingly in the bed of the stream to allow for the passage of aquatic life. g. Please provide a site map for the entire site at a scale of I "=100'scale. The attached conceptual stormwater management plan includes a site map at 1 "=200' scale. This map should provide you with a large enough scale for your evaluation. A 1":100' scale map would not easily fit on a standard 36" plan sheet. Please let us know if this is not acceptable to you. Meadowood Subdivision S&EC Project #8386.W2 March 11, 2005 Page 5 of 5 2. Impact Justification (Avoidance and Minimization) This office believes that the wetland impact labeled on the plans as impact #3 can be moved or reconfigured to minimize the impacts to the wetland Please revise the plans to minimize the impacts The engineer evaluated the alternatives to impacting this wetland. Design requirements for the intersection require that Street I connect to Street H at a 90° angle. Moving Street I to the east to avoid wetland impact would require the street to infringe on Lots 54, 55, 56 and 57. The configuration. of these lots is dependent on the suitable soils for septic systems. Street infringement on to these lots would affect the ability to build on the lots. In addition, the realignment of Street I would infringe on the Recreation Area. The preferred design for the recreation area is for it to be as large of an area as possible for the usable enjoyment of the members of the community. Relocating the road to the west would bisect this area into two smaller parcels. The functions of the wetland area being impacted are low compared to the other high quality riparian wetlands and streams that are being avoided and preserved within the open, space areas of the subdivision.

We also request written concurrence from the North Carolina Division of Water Quality for GC 3402 that the project complies with the Neuse Buffer Rules for impacts associated with the proposed road crossings. A Pre-construction Notification Application (PCN) is attached, which includes an agent authorization form. Site Location The site is + 126 acres in size and is located approximately 2000 feet southeast of the intersection of Campbell Road (SR 1383) and Holly Springs Road (SR 1152) in Wake County, NC. Project History No previous 401/404 permits have been issued for this site. Mr. Mike Horan of the NC- DWQ has visited the site to make buffer calls and his calls are reflected on the site plan. A letter from Mike Horan has not yet been received. During well drilling activities two stream channels were crossed and impacted. Both of these crossings are less than 40 linear feet each and are culverted. The wetlands and streams on the property have been flagged by S&EC. S&EC delineated the wetlands and stream channels located on the property so that a site plan could be developed that would avoid and minimize impacts to the maximum extent Charlotte Office: 236 LePhillip Court, Suite C Concord, NC 28025 Phone: (704) 720-9405 Fax: (704) 720-9406 Greensboro Office: 3817-E Lawndale Drive Greensboro, NC 27455 Phone: (336)540-8234 Fax: (336) 540-8235 January 21, 2005 S&EC Project #: 8386.W2 Page 3 of 3 Please call or email me at SClarkpSandEC.com if you have any questions.

Project Information Attach a vicinity map clearly showing the location of the property with respect to local landmarks such as towns, rivers, and roads. Also provide a detailed site plan showing property boundaries and development plans in relation to surrounding properties. Both the vicinity map and site plan must include a scale and north arrow. The specific footprints of all buildings, impervious surfaces, or other facilities must be included. If possible, the maps and plans should include the appropriate USGS Topographic Quad Map and NRCS Soil Survey with the property boundaries outlined. Plan drawings, or other maps may be included at the applicant's discretion, so long as the property is clearly defined. For administrative and distribution purposes, the USACE requires information to be submitted on sheets no larger than 11 by 17-inch format; however, DWQ may accept paperwork of any size. DWQ prefers full-size construction drawings rather than a sequential sheet version of the full-size plans. If full-size plans are reduced to a small scale such that the final version is illegible, the applicant will be informed that the project has been placed on hold until decipherable maps are provided. 1. Name of project: Meadowood Subdivision 2. T.I.P. Project Number or State Project Number (NCDOT Only): 3. Property Identification Number (Tax PIN):_ 0771769539, 0771675572 4. Location County: Wake Nearest Town: Cary Subdivision name (include phase/lot number): Meadowood Subdivision Directions to site (include road numbers, landmarks, etc.): The site is located approximately 2000 feet southeast of the intersection of Campbell Road (SR 1383) and Holly Springs Road (SR 1152) in Wake County, NC. 5. Site coordinates, if available (UTM or Lat/Long): 035°43' 11.37"N/078044'38.61 "W (Note - If project is linear, such as a road or utility line, attach a sheet that separately lists the coordinates for each crossing of a distinct waterbody.) 6. Property size (acres): f 126 acres 7. Nearest body of water (stream/river/sound/ocean/lake): Swift Creek 8. River Basin: Neuse (Note - this must be one of North Carolina's seventeen designated major river basins. The River Basin map is available at http://h2o.enr. state. nc.us/admin/maps/.) 9. Describe the existing conditions on the site and general land use in the vicinity of the project at the time of this application: The site is currently wooded. Portions of the site that were formally cultivated fields are in primary to secondary successional stages. Page 2 of 8 10. Describe the overall project in detail, including the type of equipment to be used: The proposed project is a single-family residential subdivision with the typical utilities (i.e., sewer, water, electric, etc.). Wetlands, a perennial stream an intermittent stream and their associated riparian buffers will be impacted to provide a road to connect to the eastern end of the proposed Meadowood Subdivision. Typical excavating; and grading equipment will be used during construction activities. 11. Explain the purpose of the proposed work:- The purpose for this subdivision is to provide additional housing for the area. The road crossings of the perennial and intermittent stream are required to connect to the eastern end of this property. The road location is dictated by the existence of an existing road stub on an adjacent property. Both streams transverse the entire property which make impacts unavoidable. 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. Describe previously approved wetland, stream and buffer impacts, along with associated mitigation (where applicable). 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. No previous 401/404 permits have been issued for this site. Mr. Mike Horan of the NC-DM has visited the site to make buffer calls. During well drilling activities the two stream channels were crossed and impacted. Both of these crossings are less than 40 linear feet each and proposed subdivision roads have been designed so as to cross in these locations and not result in additional impacts. The wetlands and streams on the property have been flagged by S&EC 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 permits are anticipated 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. The applicant must also provide justification for these impacts in Section VII below. All proposed impacts, permanent and temporary, must be listed herein, and must be clearly identifiable on an accompanying site plan. All wetlands and waters, and all streams (intermittent and perennial) must be shown on a Page 3 of 8 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. If this proposed impact is strictly for wetland or stream mitigation, list and describe the impact in Section VIII below. If additional space is needed for listing or description, please attach a separate sheet. 1. Provide a written description of the proposed impacts: Two buffered stream channels will be impacted by the proposed road. Proposed impacts include 130 linear feet of perennial channel, 115 linear feet of intermittent channel, 14,383 square feet of Zone 1 Neuse Buffer, and 9,418 square feet of Zone 2 Neuse Buffer. Wetlands impacted on site include 0.161 acres due to the construction of the road. 2.

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.): N/A Proposed use or purpose of pond (e.g., livestock watering, irrigation, aesthetic, trout pond, local stormwater requirement, etc.): N/A Size of watershed draining to pond: N/A Expected pond surface area: N/A 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. The client requested a detailed delineation to minimize and avoid itnnacts to iurisdictional waters including wetlands) to the maximum extent possible. Due to the nature of the property, the two stream crossings are necessary to access the eastern portion of the property. These crossings e planned for the areas previously impacted during well-drilling activities. These proposed crossings are at a nearly perpendicular angle to minimize impacts to the stream channel and were placed in the location of the previous drill rig crossings. The road resulting in Impact 3 was redesigned to avoid unnecessary impacts to the wetlands and the buffered stream. 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. Page 5 of 8 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/ncwetiands/strmgide.htm1. 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 applicant has avoided and minimized stream channel impacts by crossing stream channels in a perpendicular fashion and only 130 linear feet of "important" channel is proposed, S&EC believes that compensatory mitigation should not be required from the USACE. However, if mitigation is required the applicant proposes payment to the EEP. 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/wrp/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): 130 Amount of buffer mitigation requested (square feet): 0 Amount of Riparian wetland mitigation requested (acres): 0.161 Amount of Non-riparian wetland mitigation requested (acres): 0 Amount of Coastal wetland mitigation requested (acres): o 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 ? 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 ? 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 213 .0233 (Meuse), 15A NCAC 213 .0259 (Tar-Pamlico), 15A NCAC 2B .0250 (Randleman Rules and Water Supply Buffer Requirements), or other (please identify Yes ® No ? If you answered "yes", provide the following information: Identify the square feet and acreage of impact to each zone of the riparian buffers. If buffer mitigation is required calculate the required amount of mitigation by applying the buffer multipliers. Crossing 1 (Perennial Stream) Zone* Impact (square feet Multiplier Required Mitigation 1 7,708 3 N/A 2 5,275 1.5 N/A Total 12,984 N/A Zone 1 extends out 3U tcet perpendicular trom near bank of channel; Zone 2 extends an additional 20 feet from the edge of Zone 1. Crossing 2 (Intermittent Stream) Zone* Impact Multiplier Required (square feet) Mitigation Page 7 of 8 1 6,675 3 N/A 2 4,142 1.5 N/A Total 10,817 N/A If buffer mitigation is required, please discuss what type of mitigation is proposed (i.e., Donation of Property, Conservation Easement, Riparian Buffer Restoration / Enhancement, Preservation or Payment into the Riparian Buffer Restoration Fund). Please attach all appropriate information as identified within 15A NCAC 2B .0242 or.0260. Because both crossings will impact less than 1/3 acre of riparian buffer the proposed activity is considered "Allowable" and therefore will not require buffer mitigation. 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. The proposed protect will have less than 12% impervious coverace and will therefore not require a DW approved Stormwater plan. 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. Individual Septic System. XIII. Violations (required by DWQ) Is this site in violation of DWQ Wetland Rules (15A NCAC 2H .0500) or any Buffer Rules? Yes ? No Is this an after-the-fact permit application? Yes ® No ? *See the Prior Project History Section (Section IV). XIV. 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).
