After reviewing your application, we have decided that the impacts are covered by the N.C. Division of Water Quality (DWQ) 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 213 .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. Conditions: 1.

We also request written concurrence from the DWQ that the project complies with the 401 water quality certification associated with NWP 39 and that the project complies with the Neuse River Riparian Buffer Rule. Please note that because the proposed utility line complies with Water Quality Certification 3374, written concurrence is not required from the NC-DWQ. A Pre-construction Notification Application (PCN) is attached, which includes an agent authorization form. Site Location The site is located north of Weston Parkway (SR 1652) approximately 300 feet west from the intersection of Weston Parkway and Evans Road in Cary, Wake County, North Carolina. Project History No previous pen-nits have been issued or applied for concerning this property. On April 7 and 12, 2004 S&EC performed a detailed wetland delineation on the property. On April 30, 2004 the NC-DWQ conducted an on-site determination to review 2 features on the property for applicability to the Neuse Buffer Rules, (see attached DWQ Letter).

Impacts Permanent impacts include 126 linear feet of perennial channel and 0.33 acres of riparian buffer (Zl : 9,048, Z2: 5,459) for construction of a road crossing. A total of 59 linear feet of perennial channel and 0.058 ac of wetlands will be temporarily impacted during the installation of a sanitary sewer line. Mitigation Because the proposed impacts can not be avoided, are less than 150 linear feet of stream, and are less than 0.1 acre of wetland we do not believe mitigation should be required. However if mitigation is required we propose that payment be made to the NCEEP.

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. The proposed sewer crossing locations are at points where the stream is relatively straight to ensure a perpendicular crossing and thus will minimize impacts The sewer crossing locations were also selected as the most logical point at which the proposed sewer can tie into the Town of Care's existing sewer network adjacent to the property. The proposed stream crossing is necessary to provide two points of access to the property which is required by the Town of Cara as well as NFPA fire safety standards. For additional justification please refer to the attached memorandum from the project engineer. 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 Page 5 of 8 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/ncwctlands/stn-ngide.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 proposed impacts have been avoided and minimized to the maximum extent practicable we believe that no com enp satory mitigation should be required However if mitigation is required we propose that payment be made to the NCEEP 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 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 Page 6 of 8 If yes, does the project require preparation of an environmental document pursuant to the requirements of the National or North Carolina Environmental Policy Act (NEPA/SEPA)? Note: If you are not sure whether a NEPA/SEPA document is required, call the SEPA coordinator at (919) 733-5083 to review current thresholds for environmental documentation. Yes ? No ? X. If yes, has the document review been finalized by the State Clearinghouse? If so, please attach a copy of the NEPA or SEPA final approval letter. Yes ? No ? Proposed Impacts on Riparian and Watershed Buffers (required by DWQ) It is the applicant's (or agent's) responsibility to determine, delineate and map all impacts to required state and local buffers associated with the project. The applicant must also provide justification for these impacts in Section VII above. All proposed impacts must be listed herein, and must be clearly identifiable on the accompanying site plan. All buffers must be shown on a map, whether or not impacts are proposed to the buffers. Correspondence from the DWQ Regional Office may be included as appropriate. Photographs may also be included at the applicant's discretion. Will the project impact protected riparian buffers identified within 15A NCAC 2B .0233 (Meuse), 15A NCAC 2B .0259 (Tar-Pamlico), 15A NCAC 2B .0250 (Randleman Rules and Water Supply Buffer Requirements), or other (please identify, )? Yes ® No ? 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. ImDactS from Road Zone* Impact (square feet Multiplier Required Mitigation 1 9,048 3 NA 2 5,459 1.5 NA Total 14,507 NA * 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.

Page 7 of 8 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. The proposed buffer impacts are below the threshold that requires mitigation and are allowable as per the Neuse Riparian Buffer Rules. 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 existing impervious acreage is 0.0 acres (0%) The proposed percentage of impervious surface for the project is 9.763 (24.5%). A level spreader will be used to insure that Stormwater enters the buffers in a non-erosive flow. A DWQ approved stormwater plan is therefore not required. For a detailed breakdown of the proposed impervious area see the attached impervious surface calculations. 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. The project will tie into the Town of Cary's existing sewer 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 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).

Please accept the following (responses are bolded) to your request for further information, so that you may continue to review the project. Request #1 - Submit additional information for Impact 2D a. The velocity of the stream flow post-construction: This information is included on the revised section view, see attached. b. The slope of the culvert: This information is included on the revised section view, see attached. c. The length and width of the energy dissipater: This information is included on the revised impact map, see attached. Request #2 - Request for additional information regarding level spreaders a. FES #40 and FES#50 require level spreaders: A level spreader has been added at the outlet of FES#50. The worksheet is attached. At FES#40, we do not believe a level spreader is warranted. From the attached aerial photo it can be seen the outlet is - 1000' from Crabtree Creek and the Neuse River Riparian Buffer. As such, we believe all storm run-off will be treated and dissipated long before it enters the aforementioned buffer. b. Operations & Maintenance Agreement for all level spreaders: The Agreement is included with this response letter. c. Level spreader at FES#10 is incorrect: According to the Storm Drain Summary on Sheet 2, the discharge at FES #10 is 4.5 cfs. The level spreader is designed to be 13' per cfs, or in this case 59 feet long. The level spreader is shown as such. 1u MacKenan Drive Cary, North Carolina 27511 1 tel: 919.469.3340 1 fax: 919.467.6oo8 i www.withersravenel.com 107 Stokley Drive Suite 104 !

MAR 1 5 7005 - QUALITY Dear Mr. Tugwell and Ms. Karoly: %%ETLk1DNSAt@ STTM. ATER6RAUCH On behalf of Centex Homes (current property owner), we hereby request that the Army Corps of Engineers issue NWP 12 and 39 to cover permanent and temporary impacts to streams and wetlands resulting from the construction of a residential subdivision. We also request written concurrence from the DWQ that the project complies with the 401 water quality certification associated with-NWP 12 and 39 and that the project complies with the Neuse River Riparian Buffer Rule. A Pre-construction Notification Application (PCN) is attached, which includes an agent authorization form. Site Location The site is located north of Weston Parkway (SR 1652) approximately 300'feet west from the intersection of Weston Parkway and Evans Road in Cary, Wake County, North Carolina. Project History No previous permits have been issued or applied for concerning this property. On April 7 and 12, 2004 S&EC performed'a detailed wetland delineation on the property. On April 30, 2004 the NC-DWQ conducted an on-site determination to review 2 features on the property for applicability to the Neuse Buffer Rules, (see attached DWQ Letter). On February 23, 2005 S&EC delineated the wetlands and streams for the off property sewer impact.

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. The proposed sewer crossing locations are at points where the stream is relatively straight to ensure a perpendicular crossing and thus will minimize impacts. The sewer crossing locations were also selected as the most logical point at which the proposed sewer can tie into the Town of Care's existing sewer network adjacent to the property. The proposed stream crossing is necessary to provide two points of access to the property which is required by the Town of CqU as well as NFPA fire safety standards. For additional justification please refer to the attached memorandum from the project engineer. 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 Page 5 of 8 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.ne.us/ncwetlands/stnngide.httnl. 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 proposed impacts have been avoided and minimized to the maximum extent practicable we believe that no compensatory mitigation should be required. However if mitigation is required we propose that payment be made to the NCEEP. 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 bZ://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 IX. Environmental Documentation (required by DWQ) Does the project involye an expenditure of public (federal/state) funds or the use of public (federal/state) land? Yes ? No Page 6 of 8 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 2B .0233 (Meuse), 15A NCAC 213 .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.

Please attach all appropriate information as identified within 15A NCAC 2B .0242 or.0260. The proposed buffer impacts are below the threshold that requires mitigation and are allowable as per the Neuse Riparian Buffer Rules. 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 existing impervious acreage is 0.0 acres (0%). The proposed percentage of impervious surface for the project is 9.763 (24.5%). A level spreader will be used to insure that stormwater enters the buffers in a non-erosive flow. A DWQ approved stormwater plan is therefore not required. For a detailed breakdown of the proposed impervious area see the attached impervious surface calculations. 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. The project will tie into the Town of Care's existing sewer 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 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).

No structures are located in protected buffers. Plan details for the bypass and outlets are provided. The operation and maintenance agreement includes annual erosion and vegetation repair. The operation and maintenance agreement signed and notarized by the responsible party is provided. ' Level spreaders in series can be used on slopes of up to 15% in forested areas with leaf littler cover or on slopes of up to 25% in areas with thick ground cover or grass if designed according to the Draft Level Spreader Design Option Document. This potentially requires a minor variance in protected buffer areas. In any event the second level spreader cannot be located in Zone 1 of a protected buffer area. WITHERS ` RAVEN EL ENGINEERS 1 PLANNERS 1 SURVEYORS MEMORANDUM TO: Todd Preuninger, Soil & Environmental Consultants FROM: Jim Canfield, PE DATE: February 21, 2005 PROJECT: Weston Oaks Wetlands Justification Memo W&R No. 203015.10 am writing this memo to justify the proposed roadway crossing of Kennicott Avenue at its intersection with Weston Parkway. This parcel has public right-of-way access at both Stamford Drive and at Weston Parkway. There are 79 single-family units proposed associated with this project. The number of units requires two points of ingress and egress in accordance with Town of Cary policy as well as NFPA fire safety standards. It should also be noted that without this second crossing the project would have cul-de-sac lengths in excess of 3,300 LF, which exceeds the Town of Cary maximum of 900 LF. This second point of ingress and egress will also allow for the residential generated traffic associated with this project to be distributed in two different directions and not completely along Stamford Drive, which is an office collector street. Lastly, this parcel is adjoined to the south by the existing office development; to the west by a riparian buffer that is not being crossed; to the north by the Wake County Crabtree Creek Watershed project and associated FEMA floodplain and riparian buffers; and to the northeast by riparian buffers and FEMA floodplain. Therefore there are no other locations suited to provide an additional access to this project. We trust this information will satisfy your needs.

The features are labeled as "B and D" on the attached maps initialed by me on April 30, 2004. The Division of Water Quality (DWQ) has determined that the feature labeled as "D" on the attached maps Is subject to the Neuse Buffer Rule, this feature has been delineated and flagged in the field and is identified as flag #114. Feature Bon the attached maps has been determined as not subject to the Neuse Buffer Rule. Features A and C were not contested and therefore remain subject to the Neuse Buffer Rule. These features and their associated buffers should be identified on any future plans for this property. The owner (or future owners) should notify the DWQ (and other relevant agencies) of this decision in any future correspondences concerning this property. This on-site determination shall expire five (5) years from the date of this letter. Landowners or affected parties that dispute a determination made by the DWQ or Delegated Local Authority that a surface water exists and that it is subject to the buffer rule may request a determination by the Director. A request for a determination by the Director shall be referred to the Director in writing c/o John Dorney, DWQ Wetlands/401 Unit, 2321 Crabtree Blvd., Raleigh, NC 27604-2260. Individuals that dispute a determination by the DWQ or Delegated Local Authority that "exempts" a surface water from the buffer rule may ask for an adjudicatory hearing. You must act within 60 days of the date that you receive this letter. Applicants are hereby notified that the 60-day statutory appeal time does.not start until the affected parry (including downstream and adjacent landowners) is notified of this decision. DWQ recommends that the applicant conduct this notification in order to be certain that third parry appeals are made in a timely manner. To ask for a hearing, send a written petition, which conforms to Chapter 150B of the North Carolina General Statutes to the Office of Administrative Hearings, 6714 Mail Service Center, Raleigh, N.C. 27699-6714. This determination is final and binding unless you ask for a hearing within 60 days.
