We are also requesting 4o1-Certification and Buffer Compliance from the NC-DWQ for the impacts to jurisdictional waters and wetlands. The subject property is approximately 18.6 acres in size and is located both north and south of Airport Blvd, approximately 80o feet east of the intersection of Airport Blvd and Lake Grove Blvd. Latitude: 35.8339°N and Longitude: 78.8446°W in Morrisville, Wake County, North Carolina. The site contains an unnamed tributary to Crabtree Creek and is located in the Neuse River Basin. The Water Quality Classification for these features is: C;NSW, the Cataloging Unit for this site is: 03020201, and the Stream Index number is: 27-33-1• Project History Wetlands were delineated by Soil and Environmental Consultants and a jurisdictional determination was issued by the USACE on January 2002 (USACE AID# 200220371). Site meetings were also conducted with the NC-DWQ on September 11, 2001 (NBRRO o1-259) to verify stream origin points and subjectivity to the Neuse Buffer Rules. A copy of the buffer letter is included with the attachments. Although we were not involved in the permitting, it appears that 404 approval (AID# 200520168) and 401 certification (DWQ Exp# 04-1983), were issued for impacts in earlier phases. Proposed Impacts The proposed permanent impacts consist of 143 linear feet of perennial stream channel and o.029 acres of wetland for road construction to complete a planned connection to Airport Blvd for the Town Hall Commons Development. The impacts are summarized on the overall impact map as well as the PCN form. iii MacKenan Drive i Cary, NC 27511 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: 91o.z56.9z77 i fax: 91o.z56.z584 loz7 Sabbath Home Rd, SW i Supply, NC z846z i tel: 91o.84z•939z i fax: 91o.84z.8o19 Avoidance and Minimization Prior to site plan development, the applicant requested that a detailed wetland delineation be conducted so that impacts to wetlands and `waters' could be minimized. Impacts were minimized by crossing the channel at a nearly perpendicular angle and through the use of steeper fill slopes at the stream crossings. In order to provide residents access to Airport Blvd, the impacts could not be avoided. Stormwater Management Plan The proposed impervious for this project is expected to be approximately 39.6%, therefore constructed wetlands will be used to treat the Stormwater before it leaves the site. The Stormwater plans have been submitted to the Morrisville for their approval. A copy of the approval letter will be forwarded to your office. During construction the applicant will utilize BMP devices to prevent sediment from entering jurisdictional stream channels or wetlands. Mitigation Because impacts to perennial channels are less than z5o linear feet no mitigation is proposed. However, the applicant proposes payment to the NC-EEP to satisfy mitigation requirements for the wetland impacts. A copy of the EEP approval letter is included with the attachments. Please feel free to call if you have questions or require additional information.

Site meetings were also conducted with the NC-DWQ on September 11, 2001 (NBRRO 01-259) to verify stream origin points and subjectivity to the Neuse Buffer Rules. A copy of the buffer letter is included with the attachments. Although we were not involved in the permitting, it appears that 404 approval AID# 200520168) and 401 certification (DWQ Exp# 04-1983 ,were issued for impacts in earlier phases. 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. To the best of our knowledge no futurepermit requests are anticipated. 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. If this proposed impact is strictly for Page 7 of 12 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: The proposed impacts consist of 0.029 acres of wetlands and 143 liner feet of perennial channel. These impacts are the result of the installation of culverts, fill slope, and rip rap. 2. Individually list wetland impacts. Types of 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.

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. No Isolated wetlands exist onsite to the best of our knowledge. 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.): N/A Proposed use or purpose of pond (e.g., livestock watering, irrigation, aesthetic, trout pond, local stormwater requirement, etc.): N/A Current land use in the vicinity of the pond: 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 maybe 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 site plan development the applicant requested that a detailed wetland delineation be conducted so that impacts to wetlands and `waters' could be minimized. In order to provide the residents access to Airport Blvd the impacts could not be avoided. Impacts were minimized by crossing at a nearly perpendicular and through the use of steeper fill slopes at the stream crossings 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 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, Page 9 of 12 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/strm fide. 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 impacts to the perennial channel are less than 150 linear feet no mitigation is proposed. However, the applicant proposes payment to NC-EEP to satisfy miti ag tion requirements for the wetland impacts shown in areas 2 & 3 on the site plan. 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): N/A Amount of buffer mitigation requested (square feet): N/A Amount of Riparian wetland mitigation requested (acres): N/A Amount ofNon-riparian wetland mitigation requested (acres): 0.029 acres Amount of Coastal wetland mitigation requested (acres): N/A IX. Environmental Documentation (required by DWQ) 1. Does the project involve an expenditure of public (federal/state/local) funds or the use of public (federal/state) land? Yes ^ No 2. 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)? Page l0 of 12 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 ^ 3. 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. 1. Will the project impact protected riparian buffers identified within 15A NCAC 2B .0233 (Meuse), 15A NCAC 2B .0259 (Tar-Pamlico), 15A NCAC 02B .0243 (Catawba) 15A NCAC 2B .0250 (Randleman Rules and Water Supply Buffer Requirements), or other (please identify )? Yes ® No ^ 2. If "yes", 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. Im act Re uired Zone* , ,...,.p c ~,~ Multiplier ,~,~;.9 „*;~„ 1 7818 sq. ft. 3 (2 for Catawba) N/A 2 5351 sq. ft. 1.5 N/A Total I 13,169 sq. ft. I I N/A * Zone 1 extends out 30 feet perpendicular from the top of the near bank of channel; Zone 2 extends an additiona120 feet from the edge of Zone 1. 3. If buffer mitigation is required, please discuss what type of mitigation is proposed (i.e., Donation of Property, Riparian Buffer Restoration /Enhancement, or Payment into the Riparian Buffer Restoration Fund). Please attach all appropriate information as identified within 15A NCAC 2B .0242 or .0244, or .0260. No buffer mitigation is proposed because impacts are below the 1/3 acre and less than 1501inear feet. XI. Stormwater (required by DWQ) Describe impervious acreage (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. If percent impervious surface exceeds 20%, please provide calculations demonstrating total proposed impervious level. The proposed impervious surface will be approximately 40%. The applicant will treat all storm water onsite with constructed wetlands. A Stormwater plan has been submitted to the Cit~of Raleigh for their approval. When a copy of the plans are approved, a copy will forwarded to your office. Page 11 of 12 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. Sanitary Sewer will be utilized to treat Sewage. 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 XIV. 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.enr.state.nc.us/ncwetlands. If no, please provide a short narrative description: Because this project consists of residential development and the adjacent parcels have already been developed, we do not believe that it will result in additional impacts to downstream water quality. During construction the applicant will employ the appropriate BMP's in order to reduce the amount of sediment leaving the site. Following construction, the applicant will convert these structures to constructed wetlands so that stormwater from the site can be treated before being released. 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).

Non-regulated waters/wetlands (check if applicable):' Potentially jurisdictional waters and/or wetlands were assessed within the review area and determined to be not jurisdictional. Explain: Boxes checked below shall be supported by completing the appropriate sections in Section III below. ~ For purposes of this form, an RPW is defined as a tributary that is not a TNW and that typically flows year-round or has continuous flow at least "seasonally" (e.g., typically 3 months). 3 Supporting documentation is presented in Section III.F. SECTION III: CWA ANALYSIS A. TNWs AND WETLANDS ADJACENT TO TNWs The agencies will assert jurisdiction over TNWs and wetlands adjacent to TNWs. If the aquatic resource is a TNW, complete Section III.A.1 and Section III.D.1. only; if the aquatic resource is a wetland adjacent to a TNW, complete Sections III.A.1 and 2 and Section IILD.1.; otherwise, see Section IILB below. 1. TNW Identify TNW: Summarize rationale supporting determination: 2. Wetland adjacent to TNW Summarize rationale supporting conclusion that wetland is "adjacent": B. CHARACTERISTICS OF TRIBUTARY (THAT IS NOT A TNW) AND ITS ADJACENT WETLANDS (IF ANY): This section summarizes information regarding characteristics of the tributary and its adjacent wetlands, if any, and it helps determine whether or not the standards for jurisdiction established under Rapanos have been met. The agencies will assert jurisdiction over non-navigable tributaries of TNWs where the tributaries are "relatively permanent waters" (RPWs), i.e. tributaries that typically flow year-round or have continuous flow at least seasonally (e.g., typically 3 months). A wetland that directly abuts an RPW is also jurisdictional. If the aquatic resource is not a TNW, but has year-round (perennial) flow, skip to Section III.D.2. If the aquatic resource is a wetland directly abutting a tributary with perennial flow, skip to Section IILD.4. A wetland that is adjacent to but that does not directly abut an RPW requires a significant nexus evaluation. Corps districts and EPA regions will include in the record any available information that documents the existence of a significant nexus between a relatively permanent tributary that is not perennial (and its adjacent wetlands if any) and a traditional navigable water, even though a significant nexus finding is not required as a matter of law. If the waterbody° is not an RPW, or a wetland directly abutting an RPW, a JD will require additional data to determine if the waterbody has a significant nexus with a TNW. If the tributary has adjacent wetlands, the significant nexus evaluation must consider the tributary in combination with all of its adjacent wetlands. This significant nexus evaluation that combines, for analytical purposes, the tributary and all of its adjacent wetlands is used whether the review area identified in the JD request is the tributary, or its adjacent wetlands, or both. If the JD covers a tributary with adjacent wetlands, complete Section III.B.1 for the tributary, Section III.B.2 for any onsite wetlands, and Section III.B.3 for all wetlands adjacent to that tributary, both onsite and offsite. The determination whether a significant nexus exists is determined in Section III.C below. 1.

Explain: Identify specific pollutants, if known: 6A natural or man-made discontinuity in the OHWM does not necessarily sever jurisdiction (e.g., where the stream temporarily flows underground, or where the OHWM has been removed by development or agricultural practices). Where there is a break in the OHWM that is unrelated to the waterbody's flow regime (e.g., flow over a rock outcrop or through a culvert), the agencies will look for indicators of flow above and below the break.

For each wetland, specify the following: Directly abuts? (Y/Nl Size (in acres) Directly abuts? (Y/N) Size (in acres) Summarize overall biological, chemical and physical functions being performed: C. SIGNIFICANT NEXUS DETERMINATION A significant nexus analysis will assess the flow characteristics and functions of the tributary itself and the functions performed by any wetlands adjacent to the tributary to determine if they significantly affect the chemical, physical, and biological integrity of a TNW. For each of the following situations, a significant nexus exists if the tributary, in combination with all of its adjacent wetlands, has more than a speculative or insubstantial effect on the chemical, physical and/or biological integrity of a TNW. Considerations when evaluating significant nexus include, but are not limited to the volume, duration, and frequency of the flow of water in the tributary and its proximity to a TNW, and the functions performed by the tributary and all its adjacent wetlands. It is not appropriate to determine significant nexus based solely on any specific threshold of distance (e.g. between a tributary and its adjacent wetland or between a tributary and the TNW). Similarly, the fact an adjacent wetland lies within or outside of a floodplain is not solely determinative of significant nexus. Draw connections between the features documented and the effects on the TNW, as identified in the Rapanos Guidance and discussed in the Instructional Guidebook. Factors to consider include, for example: • Does the tributary, in combination with its adjacent wetlands (if any), have the capacity to carry pollutants or flood waters to TNWs, or to reduce the amount of pollutants or flood waters reaching a TNW? • Does the tributary, in combination with its adjacent wetlands (if any), provide habitat and lifecycle support functions for fish and other species, such as feeding, nesting, spawning, or rearing young for species that are present in the TNW? • Does the tributary, in combination with its adjacent wetlands (if any), have the capacity to transfer nutrients and organic carbon that support downstream foodwebs? • Does the tributary, in combination with its adjacent wetlands (if any), have other relationships to the physical, chemical, or biological integrity of the TNW? Note: the above list of considerations is not inclusive and other functions observed or known to occur should be documented below: I.

SECTION III: CWA ANALYSIS A. TNWs AND WETLANDS ADJACENT TO TNWs The agencies will assert jurisdiction over TNWs and wetlands adjacent to TNWs. If the aquatic resource is a TNW, complete Section III.A.1 and Section III.D.1. only; if the aquatic resource is a wetland adjacent to a TNW, complete Sections III.A.1 and 2 and Section III.D.1.; otherwise, see Section III.B below. 1. TNW Identify TNW: Summarize rationale supporting determination: 2. Wetland adjacent to TNW Summarize rationale supporting conclusion that wetland is "adjacent": B. CHARACTERISTICS OF TRIBUTARY (THAT IS NOT A TNW) AND ITS ADJACENT WETLANDS (IF ANY): This section summarizes information regarding characteristics of the tributary and its adjacent wetlands, if any, and it helps determine whether or not the standards for jurisdiction established under Rapanos have been met. The agencies will assert jurisdiction over non-navigable tributaries of TNWs where the tributaries are "relatively permanent waters" (RPWs), i.e. tributaries that typically flow year-round or have continuous flow at least seasonally (e.g., typically 3 months). A wetland that directly abuts an RPW is also jurisdictional. If the aquatic resource is not a TNW, but has year-round (perennial) flow, skip to Section III.D.2. If the aquatic resource is a wetland directly abutting a tributary with perennial flow, skip to Section III.D.4. A wetland that is adjacent to but that does not directly abut an RPW requires a significant nexus evaluation. Corps districts and EPA regions will include in the record any available information that documents the existence of a significant nexus between a relatively permanent tributary that is not perennial (and its adjacent wetlands if any) and a traditional navigable water, even though a significant nexus finding is not required as a matter of law. If the waterbody° is not an RPW, or a wetland directly abutting an RPW, a JD will require additional data to determine if the waterbody has a significant nexus with a TNW. If the tributary has adjacent wetlands, the significant nexus evaluation must consider the tributary in combination with all of its adjacent wetlands. This significant nexus evaluation that combines, for analytical purposes, the tributary and all of its adjacent wetlands is used whether the review area identified in the JD request is the tributary, or its adjacent wetlands, or both. If the JD covers a tributary with adjacent wetlands, complete Section III.B.1 for the tributary, Section III.B.2 for any onsite wetlands, and Section III.B.3 for all wetlands adjacent to that tributary, both onsite and offsite. The determination whether a significant nexus exists is determined in Section III.C below. 1.

SIGNIFICANT NEXUS DETERMINATION A significant nexus analysis will assess the flow characteristics and functions of the tributary itself and the functions performed by any wetlands adjacent to the tributary to determine if they significantly affect the chemical, physical, and biological integrity of a TNW. For each of the following situations, a significant nexus exists if the tributary, in combination with all of its adjacent wetlands, has more than a speculative or insubstantial effect on the chemical, physical and/or biological integrity of a TNW. Considerations when evaluating significant nexus include, but are not limited to the volume, duration, and frequency of the flow of water in the tributary and its proximity to a TNW, and the functions performed by the tributary and all its adjacent wetlands. It is not appropriate to determine significant nexus based solely on any specific threshold of distance (e.g. between a tributary and its adjacent wetland or between a tributary and the TNW). Similarly, the fact an adjacent wetland lies within or outside of a floodplain is not solely determinative of significant nexus. Draw connections between the features documented and the effects on the TNW, as identified in the Rapanos Guidance and discussed in the Instructional Guidebook. Factors to consider include, for example: • Does the tributary, in combination with its adjacent wetlands (if any), have the capacity to carry pollutants or flood waters to TNWs, or to reduce the amount of pollutants or flood waters reaching a TNW? • Does the tributary, in combination with its adjacent wetlands (if any), provide habitat and lifecycle support functions for fish and other species, such as feeding, nesting, spawning, or rearing young for species that are present in the TNW? • Does the tributary, in combination with its adjacent wetlands (if any), have the capacity to transfer nutrients and organic carbon that support downstream foodwebs? • Does the tributary, in combination with its adjacent wetlands (if any), have other relationships to the physical, chemical, or biological integrity of the TNW? Note: the above list of considerations is not inclusive and other functions observed or known to occur should be documented below: 1. Significant nexus findings for non-RPW that has no adjacent wetlands and flows directly or indirectly into TNWs. Explain findings of presence or absence of significant nexus below, based on the tributary itself, then go to Section III.D: 2. Significant nexus findings for non-RPW and its adjacent wetlands, where the non-RPW flows directly or indirectly into TNWs.

The required area of mitigation to compensate for impacts to the protected riparian buffers is 5,532 square feet as required under this Authorization Certificate and 15A NCAC 2B .0242. We understand that you wish to make a payment into. the RiQarian $uf~e~RestarationF.und administe~~r-~i~IG-Ecosystem~Enhancemerit Program (EEl') to rraret this mitigation requirement. This has been determined by the DWQ to be a suitable method to meet the mitigation requirement. In accordance with 15A NCAC 2B .0242(7) this contribution will satisfy our compensatory mitigation requirements under 15A NCAC 2B .0233(10). Until the EEP receives and clears your check (made payable to: DENR - Ecosystem Enhancement Program Office), no impacts specified in this Authorization Certificate shall occur. The EEP should be contacted at (919) 733-5208 if you have any questions concerning payment into the Riparian Buffer Restoration Fund. You have one month from the date of this-approval to make this payment. For accounting purposes, this Authorization Certificate authorlxes payment into the Riparian Buffer Restoration Fend to compensate for 10329 r~ of required rlparian buffer mitlgation for impacts to S,S32 ftz of riparian buffers; 03-0402 river and subbasin." 3. Diffuse Flow All stormwater shall be directed as diffuse flow at non-erosive velocities through the protected stream buffers and will not re~oncenttate before discharging into the stream as identified within 15A NCAC 2$ .0233(5). 4. Protective Fencing The outside buffer, wetland or water boundary and along the construction corridor within these _.. _ boundaries. a~r9ved Hader-this.authorization sl;all be-clearly marked with orange warning fencing (or similar high visibility material) for the areas that have been approved to infringe within the buffer, wetland or water prior to any land disturbing activities to ensure compliance with 15A NCAC 2B 33 and GC 3402. 5. No Impacts to Zone No impacts shall occur to Zone 1 of the protected riparian buffers (except for uses and activities designated as "exempt" within 15A NCAC 02B .0233), unless otherwise approved by the DWQ. 6. Culvert Installation Culverts required for this project shall be installed in such a manner that the original stream profiles are not altered. Existing stream dimensions (including the cross section dir~nsions, pattern, and longitudinal profile) must be maintained above and below locations of each culvert. Culverts shall be designed and installed to allow for aquatic life movement as well as to prevent head cutting of the streams. If any of the existing pipes are or become perched, the appropriate stream grade shall be re- f Centex Homes Page 3 of 5 1121 /05 established or, if the pipes installed in a perched manner, the pipes shall be removed and re-installed COrreCtly. Placement. of culverts and other structures in waters, streams, and wetlands must be placed below the elevation of the streambed by ones foot for all culverts with a diameter greater than 48 inches, and 20 percent of the culvert diameter for culverts having a diameter less than 48 inches, to allow low flow passage of water and aquatic life.. Design and placement of culverts and other structures including. temporary erosion control measures shall not be conducted in a manner that may result in dis- equilibrium of wetlands or stream beds. or banks, adjacent to or upstream and down stream of the above structures. The applicant is required to provide evidence that the equilibrium shall be maintained if requested in writing by DVi~Q. ' 7. Far the proposed 4 barrel culvert located at impact #6, the .design and installation of sills in conjunction with multiple barrel culverts should be such that the culvert cross-section mimics the stream bankfull dimension (i.e. stream cross sectional area and geometric configuration) as closely as possible. `The sdls'sl"~7e'pla~`on the two outside culverts and have a height equal to the bankfull discharge depth. No impacts shall be incurred anywhere on the project until an acceptable design is submitted to, and approved by, the NC Division of Water Quality. 8.. It is our understanding that a 48" pipe is being required for impact #2. Culverts 48" diameter or greater shall be buried a foot and parallel to the slope of the streambed. Culverts less than 48" in diameter or less shall be buried to a depth equal or greater than 20% their size for aquatic life passage. These measurements must be based on natural thalweg depths. 9. Impervious Surface Condition If the amount of impervious surface exceeds 309'0, then a stormwater management plan, approved by DWQ, shall be implemented. The DWQ has not approved the proposed stormwater management plan, included in the application dated 22 December 2004. 10. Construction Stormwater Permit NCGO10000 _ Upon the approval of an Erosion and Sedimentation Control Plan issued by the Division of Land Resources (DLR) or a DLR delegated local erosion and sedimentation control.pzogram, an NPDPS General stormwater permit (NCG410000) administered by DWQ is automatically issued to the project. This.General Permit allows stoneswater to be discharged during land disturbing construction _ activities as'Stipulated~~by nonditions in the permit. If your project is covered by this permit ... [applicable to construction projects that disturb one (1) or more acres], full compliance with permit conditions including the sedimentation control plan, self-monitoring, record keeping and reporting requirements are required. A copy of this permit and monitoring report forms may be found at httn•//h2o.enr.state.ne.us/su/Fornts Documents.htm. 11. Deed Notifications Deed notifications or similar mechanisms shall be placed on all retained jurisdictional wetlands, .waters and protective buffers in order to assure compliance for future wetland, water and buffer impact. These mechanisms shall be put in place prior to impacting any wetlands, waters and/or buffers approved for impact under this Certification Approval aad Authorization Certificate. A sample deed notification can be downloaded from the 401/Wetlands Unit web site at ' http:/Th2o.enr.state.nc.us/ncwetlartds.

It was determined that the channel8 present on the property shown on either the Wake County Soil Survey and /or USES Cary, NC quad map that are subject to protection under the Neuse River Basin: Nutrient Sensitive Waters Management Strategy; Protection and Maintenance of Existing Riparian Areas, North Carolina Administrative Code T15A:02B.0233. The portion of the property north of McCrimmon Parkway is in the Cape Fear River Basin and is therefore not currently subject to buffer regulations. The feature labeled "A" on the attached map and the Wake County Soil Survey is subject, feature `B" at flag #SOl, feature "C" at flag #205,, and feature "D" (from flag #100 to flag labeled stop NBR) which are showp on the attached map. The channels are unnamed tributaries of Crabtree Creek. This letter only addresses the applicability of the Neuse Buffer Rules. For information relevant to wetlands and other impacts, please contact the Central Office at 733-17$6.

It is the responsibility of the applicant to contact these agencies to determine if payment to the NCEEP will be approved. This acceptance is valid for six months from the date of this letter and is not transferable. If we have not received a copy of the issued 404 Permit/401 CertificatiodCAMA permit within this time frame, this acceptance will expire. It is the applicant's responsibility to send copies of the permits to NCEEP. Once NCEEP receives a copy of the permit(s) an invoice will be issued based on the required mitigation in that permit and payment must be made prior to conducting the authorized work. The amount of the In Lieu Fee to be paid to NCEEP by an applicant is calculated based upon the Fee Schedule and policies listed at www.nceep.net. Based on the information supplied by you the impacts that may require compensatory mitigation are summazized in the following table. NEUSE 03020201 Stream (feet) Wetlands (acres) Buffer I (Sq. Ft.)
