Specifically, the application reflects the following revisions: 1.) Sanitary sewer lines for the proposed project have been added to the Impact Map. The majority of the sanitary sewer lines will be constructed within the roadway. However, the connection of the proposed sanitary sewer system to the existing sanitary sewer system located within and along the riparian buffer requires impacting a small amount of riparian buffer and wetlands. The application has been revised to include these additional impacts. 2.) The percent imperviousness area based on built-out conditions is 28.6. The Stormwater Section of the application provides detailed information regarding the calculations of the percent imperviousness area. r6 3.) The proposed road crossing is necessary to provide access to the property. The location of the crossing is dictated by the connection to the existing subdivision road. However, the design of the road crossing has been revised using headwalls to reduce the amount of stream channel impact to 142 linear feet. 5 r NCDENR -DWQ Parkview Building 2321 Crabtree Boulevard, Ste.250 North Carolina 27604 4.) Since the time of the original permit submittal, modifications have been made to the proposed storm water network to ensure maintenance of diffuse flow through the buffer. Please refer to the Stormwater Section of the revised application and the Impact Map for information regarding the specifications and construction details for the stormwater treatment devices that are proposed.

Name of project: Pearl Ridge Subdivision 2. T.I.P. Project Number or State Project Number (NCDOT Only): NA 3. Property Identification Number (Tax PIN): 1721994838 4. Location County: Wake Nearest Town: Raleigh Subdivision name (include phase/lot number): Pearl Ridge Subdivision Directions to site (include road numbers, landmarks, etc.): The site is located northwest of Pearl Road approximately 2000 feet southwest of its intersection with Rock Quarry Road. Please refer to the USGS topographic quadrangle attached to the original application for the location of the proposed subdivision. 5. Site coordinates, if available (UTM or Lat/Long): 35° 43' 37" N 78° 33' 53" 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): -26 acres 7. Nearest body of water (stream/river/sound/ocean/lake): Unnamed tributary of Big Branch 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.ne.us/admin/mans/.) 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 forested except for the power line Page 6 of 14 easement that runs through the property. The land use in the vicinity of the project consists of forestland, small farms, and residential subdivisions. 10. Describe the overall project in detail, including the type of equipment to be used: The proposed subdivision consists of approximately 93 lots. It involves construction of access roads, one of which crosses a buffered stream some light rg ading of a few lots, and installation of a sanitary sewer system. Heavy equipment typical of road and utility construction and light rg adung will be used to construct the project. 11. Explain the purpose of the proposed work: The purpose of the proposed work is to provide the infrastructure necessary for a 93-lot subdivision. This includes road access across a perennial stream channel that separates the property from Pearl Road, grading the area needed for house placement on six lots, and installation of a sanitary 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, NCDWQ 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. An application for this project was originally submitted on June 13, 2002 (DW Project # 02- 0948). The intent since the application was originally submitted was to utilized headwalls in order the minimize the impacts of the proposed road crossing to less than 150 of stream channel impact. On June 19, 2002, NCD)MQ placed the project on hold to clarify the amount of stream impact because the stream impacts were referenced in the cover letter as ±149 linear feet. The USACE issued a Nationwide Permit 39 for the proposed project under Action ID # 200221161. On October 11, 2002, a smaller scale map was submitted to NCDWO to clarify the stream impacts. However, an earlier version of the project map was inadvertently used, in which the crossing had not been revised to minimize the impacts. NCDWO issued another letter on October 24, 2002 indicating; that the impact map showed impacts that exceeded 150 linear feet of stream channel and requested additional information regarding the stormwater management ment plan and sanitary sewer facilities for the project. This application has been revised to accurately depict the proposed road crossing and provided the additional information requested for the project. Upon compiling the additional information, two additional impacts (#3 & #4) were identified associated with the proposed sanitary sewer. As indicated in the original application, S&EC conducted a wetland delineation on March 12, 2002. The wetland area is shown on the attached Impact Map. S&EC's data forms completed for the wetland delineation were submitted with the original application. The stream shown as Page 7 of 14 buffered on the Impact Map is the only feature on the site that is depicted on the applicable USGS topographic map and Wake County Soil Survey map. 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. Future permit requests are not anticipated for this project 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 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: One access road crosses a buffered stream channel and six lots require filling a small amount of wetland area. 2. Individually list wetland impacts below: Wetland Impact Area of Located within Distance to Site Number Type of Impact* Impact 100-year Fooodplain** Nearest Stream Type of Wetland*** (indicate on map) (acres) (es/no) (linear feet) 1 permanent/fill 0.12 no 0 Headwater forest 4 tempoor on/ 0.01 no 0 Headwater forest * List each impact separately and identify temporary impacts.

Maps are available through the FEMA Map Service Center at 1-800-358-9616, or online at h4pJ/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: -1.5 Total area of wetland impact proposed: 0.13 acre Page 8 of 14 3. Individually list all intermittent and perennial stream impacts below: Stream Impact Site Number (indicate on map) Type of Impact* Length of Impact (linear feet) Stream Name** Average Width of Stream Before Impact Perennial or Intermittent? (please specify) 2 culvert/rip-rap 142 UT to Big Branch 6 perennial * 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 internet sites also allow direct download and printing of USGS maps (e.g., www.to Qzone.coni, www.MMuest.com, etc.). Cumulative impacts (linear distance in feet) to all streams on site: 142 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 Site Number (indicate on map) Type of Impact* Area of Impact (acres) Name of Waterbody (if applicable) Type of Waterbody (lake, pond, estuary, sound, bay, ocean, etc.) NA * 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.): NA Proposed use or purpose of pond (e.g., livestock watering, irrigation, aesthetic, trout pond, local stormwater requirement, etc.): 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 Page 9 of 14 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. Because a buffered stream channel separates theproperty from Pearl Road the road crossing of this stream (Impact #2) is required to gain access to the property. The location of the crossing is dictated by the connection to the existing subdivision road. In addition, the sanitary sewer system for the proposed project must be connected to an existing sanitary sewer line located within and along tL,he edge of the riparian buffer in two places which will require impacts to the riparian buffer (Impact #3) and wetlands (Impact 94) The rest of the subdivision was designed to avoid the riparian buffer present on the property A small amount (0.12 acre) of wetland fill (Impact #1) is also required to utilize 6 lots within the proposed subdivision. VIII. Mitigation DWQ - In accordance with 15A NCAC 2H .0500, mitigation may be required by the NC Division of Water Quality for projects involving greater than or equal to one acre of impacts to freshwater wetlands or greater than or equal to 150 linear feet of total impacts to perennial streams. USACE - In accordance with the Final Notice of Issuance and Modification of Nationwide Permits, published in the Federal Register on 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 . 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 permanent impacts to wetlands and stream channels do not exceed 150 linear feet of stream channel and 1 acre of wetlands impacts were avoided and minimized to the Page 10 of 14 maximum extent practicable by utilizing headwalls and aligning the road to cross the stream channel perpendicularly and a riparian buffer will be maintained mitigation should not be required by the USACE or NCDWQ for impacts to streams and wetlands. The riparian buffer impacts resulting from the road crossing does not exceed 150 linear feet or 1/3 acre Therefore riparian buffer mitigation for the proposed road crossing` should not be required by NCDWQ The proposed sanitary sewer impacts to the riparian buffer are unavoidable due to the location of the existing sanitary sewer line. Only one of the sanitary sewer connections impacts the riparian buffer (Impact #3) Most of the proposed easement is located within the existing easement which is considered an existing use that is exempt. Therefore only the portion of the easement located outside of the existing easement is included as an impact to the riparian buffer. Because this connection is unavoidable and results in a small amount of Zone 1 impact we believe mitigation for the impact to Zone 1 of the riparian buffer should not be required However, if NCDWQ requires mitigation then the applicant proposes to satisfy the requirement through payment to the NC Wetland Restoration Program_ _ 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/mn/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): NA Amount of buffer mitigation requested (square feet): 147 if required by NCDWQ Amount of Riparian wetland mitigation requested (acres): NA Amount of Non-riparian wetland mitigation requested (acres): NA Amount of Coastal wetland mitigation requested (acres): NA 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)?

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 )9 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. Zone* uuaarpe f?)

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. If NCDWQ requires mitigation for Impact #3 the Mlicant proposes payment into the Riparian Buffer Restoration Fund. Page 12 of 14 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. Using proposed development plans and associated data for the Pearl Ridge Subdivision - Phase III a percent impervious was calculated for the project site. This estimate was based on the average proposed residence footprint (including ?patios, driveways and sidewalks) and the proposed development's common impervious area (street pavement, curb & gutter, and sidewalks). The total project area consists of 25.64 acres. Of this area, a total of 7.33 acres (3.93 acres from lots and 3.40 acres from common areas was estimated as impervious. The resultant project percent impervious has been estimated at approximated 28.6 percent (7.33 acres divided by 25.64 acres). These analyses were performed by Thompson & Associates, Raleigh, NC, a sub-consultant of McIntyre & Associates PLLC Since the time of the original permit submittal, modifications have been made to the proposed storm water network These modifications included relocating (and redirecting) portions of the previously proposed storm water network to adjust the location of proposed storm water outfalls. Additionally, in order to meet the Neuse River Basin nitrogen control requirements (total d detention was nitrogen reduction and "no net" peak flow increase) storm water treatment an necessary Surface Sand Filters have been designed for treatment of storm water at the five proposed outfalls The locations of treatment devices have been shown on the proposed site plan Construction details for the Surface Sand Filters (numbers 1 through 5) have been provided on the attached sheets Of these proposed devices three (numbers 1 2 and 3) will discharge through the buffer on the Unnamed Tributau of Big Branch Accordingly Level Spreaders have been sized to safely handle the associated discharges and provide diffuse flow through the buffer. A detail of the Level Spreader has been attached. The analyses and sizing of the proposed storm water treatment devices were performed by Thompson & Associates, Raleigh, NC a sub-consultant of McIntyre & Associates PLLC 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. Municipal sanitary sewer XUL 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 Page 13 of 14 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). / ///l X151 ® Applicant/Agent's Signatui# 1 Date (Agent's signature is valid only if an authorization letter from the applicant is provided.)

Division of Water Quality o v,e -c October 24, 2002 DWQ# 02-0948 Wake County CERTIFIED MAIL-REQUEST RECEIPT REQUESTED Wilco Properties, Inc. Attn: Diane W. Wallace, VP 1708 Trawick Road, Suite 209 Raleigh, NC 27604 Dear Ms. Wallace: On October 11, 2002, the Division of Water Quality (DWQ) was notified by receipt of your additional information regarding your plans to impact around` 1491 ear feet of stream, 0.24 acres of stream buffers and 0.12 of wetlands at Pearl Ridge Subdivision a unnaniied tri tart' to Big Branch for the purpose of a road crossing in Wake County. Approval from DWQ is required to impact these wetlands, streams and buffers. Please provide seven copies of the following information and refer to the DWQ number listed above in your reply. 1. Please locate any planned sewer lines on the site plan (if any). 2. Please specify the percent of project imperviousness area based on the estimated built-out conditions. 3. This Office believes that the stream impacts for the road crossing exceed 150 feet as shown on the plans. Please address whether the road crossing can be moved or reconfigured to avoid the impacts to the stream. If not, stream mitigation may be required. 4. The four stormwater discharges at the location on the plans do not appear to provide diffuse flow through the buffer because rip rap aprons tend to release concentrated flow and to discharge points are on steep sloops. Please revise the plans and provide calculations to show that diffuse flow will be achieved through the entire buffer.

S.) below: Open Water Impact Site Number (indicate on map) Type of Impact* Area of Impact (acres) Name of Waterbody (if applicable) Type of Waterbody (lake, pond, estuary, sound, bay, ocean, etc.) NA * 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.): NA Proposed use or purpose of pond (e.g., livestock watering, irrigation, aesthetic, trout pond, local stormwater requirement, etc.): 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. Because a buffered stream channel separates the vrovertv_from Pearl Road, the road crossina of the buffered stream is required to gain access to the property. The rest of the subdivision was designed to avoid the riparian buffer present on the property. A small amount of wetland fill is required to utilize 6 lots VIII. Mitigation DWQ - In accordance with 15A NCAC 2H .0500, mitigation may be required by the NC Division of Water Quality for projects involving greater than or equal to one acre of impacts to freshwater wetlands or greater than or equal to 150 linear feet of total impacts to perennial streams. USACE - In accordance with the Final Notice of Issuance and Modification of Nationwide Permits, published in the Federal Register on March 9, 2000, mitigation will be required when Page 9 of 12 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.htmi. 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 impacts to wetlands and stream channels do not exceed 150 linear feet of stream channel and 1 acre of wetlands and impacts were avoided and minimized to the maximum extent practicable by aligning the road to cross the stream channel perpendicularly maintaining riparian buffers mitigation should not be required by the USACE or NCDWQ for impacts to streams and wetlands. Additionally, riparian buffer impacts resulting from the road crossing of the buffered stream do not exceed 150 linear feet or 1/3 acre. Therefore, riparian buffer mitigation should not be required by_NCDWQ. 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): NA Amount of buffer mitigation requested (square feet): NA Amount of Riparian wetland mitigation requested (acres): NA Amount of Non-riparian wetland mitigation requested (acres): NA Amount of Coastal wetland mitigation requested (acres): NA Page 10 of 12 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)?
