Approval from DWQ is required to disturb these areas. Please provide 7 copies of the following information and refer to the DWQ # listed above in your reply. Please show these on maps of suitable scale (for instance 1" = 100 feet) so we can begin to determine your projects' compliance with 15A NCAC 2H.0500. 1. Please locate any planned sewer lines on the site plan. 2. Please indicate the diffuse flow provision measures on the site plan. 3. Are the sanitary sewer lines existing or are they being proposed? If proposed, please provide information pertaining to such impacts to the Neuse Riparian Buffers. 4. Does the plan have mitigation already built or is it just a conceptual plan? Please telephone Beth Barnes at 919-715-8354 if you have any questions or would require copies of our rules or procedural materials. This project will remain on hold as incomplete in accordance with 15A NCAC 2H .0505(c). The processing time for this application will begin when this information is received. If we do not hear from you by writing within three (3) weeks we will assume you no longer want to pursue the project and will consider it withdrawn.

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. This approval shall replace the one Issued on May 27, 2003. This approval is only valid 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 authorization and approval letter and is thereby responsible for complying with all conditions. For this approval to be valid, you must follow the conditions listed below. Conditions: 1. Diffuse Flow An additional condition is that all stormwater shall be directed as diffuse flow at non-erosive velocities through the protected stream buffers and will not re-concentrate before discharging into the stream as identified within 15A NCAC 2B.0233(5). 2. Certificate of Completion Upon completion of all work approved within this authorization, and any subsequent modifications, the applicant is required to return the attached certificate of completion to the 401/Wetlands Unit, North Carolina Division of Water Quality, 1650 Mail Service Center, Raleigh, NC, 27699-1650. 3. Protective Fencing The outside buffer boundary and along the construction corridor within these boundaries approved under this authorization shall be clearly marked with orange fabric fencing (or similar high visibility material) for the areas that have been approved to infringe within the buffer. This fencing shall be installed prior to any land disturbing activities North Carolina Division of Water Quality, WETLANDS / 401 UNIT 2321 Crabtree Blvd., Raleigh, NC 27604-2260 (Location) 1650 Mail Service Center, Raleigh, NC 27699-1650 (Mailing Address) 919-733-1786 (phone), 919-733-6893 (fax), http://h2o.enr.state.nc.us/ncwetlands Page 2 of 2 to ensure compliance with 15A NCAC 2B .0233. The protective fencing should be removed once construction is complete. 4. Temporary Sediment and Erosion Control Devices Temporary sediment and erosion control devices within Zone 1 to control impacts associated with uses approved by the DWQ is "allowable" and does not require mitigation. As long as the only impacts to Zone 1(i.e., the 305 square feet) are associated solely with temporary sediment and erosion control devices and the area is restored to it's original grade and replanted, then the DWQ will not require mitigation for these areas. 5. Grading and Revegetation within Zone 2 The plans provided along with the application depict grading activities within Zone 2 of the protected buffer. This activity is designated as "exempt" under the Buffer Rule provided that fill is not placed in Zone 1, diffuse flow is maintained as per the Buffer Rule, the disturbed areas are stabilized and revegetated, and the health of the existing vegetation in Zone 1 is not compromised. Any disputes over determinations regarding this Authorization Certificate (associated with the approved buffer impacts) shall be referred in writing to the Director for a decision. The Director's decision is subject to review as provided in Articles 3 and 4 of G.S. 150B. This letter completes the review of the "No Practical Alternatives" determination under 15A NCAC 2B .0233. If you have any questions or would like a copy of the buffer rules, please call (919) 733-1786. This letter does not authorize any impacts to either Waters of the United States or Waters of the State. Please contact the US Army Corps of Engineers (USACE) or NC Division of Water Quality (DWQ) if any impacts are proposed to either of these waters. Sincerely, j - l?Alan W. Klimek, P.E.

According to the Division of Land Resources, the sediment traps are undersized for the project area and must be redesigned to meet their specifications. Therefore, I am submitting a new site plan and calculations and a modified Pre-Construction Notification Application for your review and approval. The original PCN stated the impacts to Zone 1 as approximately 248 ft2 and impacts to Zone 2 as 3,171 ft2. The redesigned sediment traps will now temporarily impact approximately 305 ft2 of Zone 1, and 4045 ft2 of Zone 2. The total mitigation owed for the project will now be approximately 6,982 112 (5,501 ft2 was previously submitted). No other aspects of the project have changed. As discussed by phone, I have made the necessary changes by hand directly on a copy of the original PCN.

Page 12 of 12 Additional Information to accompany the Pre-Construction Notification Application III. Project Information "a 0 9. Describe the existing conditions on the site and general land use in the vicinity of the project at the time of this application: Response: The land area currently is a heavily wooded tract of land bounded by Lake Raleigh to the north and South Creek to the south. The land has a mixture of pine trees and various species of deciduous trees with small under story. There is a ridgeline located generally in the middle of the land. The topography is gently sloping to the lake and creek. Rainfall runoff flows from this ridgeline either into Lake Raleigh or South Creek. There is an old single lane farm road that runs through the property in a southwest to northeast direction. This farm road can be used but is not very well maintained. The access point is off of Trailwood Drive and goes in behind the Centennial Campus Middle School. The farm road stops at Walnut Creek just behind the dam. A City of Raleigh sewer pipe runs parallel to South Creek on the north side of the creek. This sewer pipe and its easement are issues that must be dealt with in the design of this project. The general land use in this area is undeveloped land in an urban setting. Currently, students and faculty use this land for riding mountain bikes or taking hikes through a wooded area within the City of Raleigh limits. It is not used for farmland or pastureland. 10. Describe the overall project in detail, including the type of equipment to be used: Response: This project will provide a service road for the proposed Alumni Center. The Alumni Center is a proposed $25,000,000 building that is being planned for construction on the ridgeline of the site. This project is in the planning and fund raising stages. The service drive will tie into an access road that will serve for egress to the main entrances to the Alumni Center and to the proposed Conference and Convention Center. This project will prepare a 500 foot roadbed beginning at the access drive and extending to the southwest and oriented somewhat parallel to South Creek. The 500-foot roadbed will be rough graded to the proposed final elevation. The beginning 100 feet of the service drive will be completed with storm drainage features, curb and gutter, 12-inches of ABC, 3-inches of H-binder and 2.5-inches of I-2. A 3' x 3' concrete ductbank containing 8-5" diameter electrical PVC conduits, 3-5" diameter telecommunication PVC conduits, 4-1.5" diameter tetraduct conduits, and 1-2" diameter control conduit will be installed under the road surface. Also, a 12" diameter waterline will be installed under the road surface as well. No gas or sanitary sewer pipes will be installed as part of this project. The Alumni Center will be responsible for installing these two systems when this project is constructed. The type of equipment to be used will be typical grading equipment such as trackhoes, backhoes, dump trucks, sheepsfoots, tamping devices, and steel rollers. 1 It. Explain the purpose of the proposed work: Response: The purpose of this project is to provide the same sort of accessibility to the Alumni Center side of the Access Road (west) that is being provided for the Conference and Convention Center side (east side). This 500-feet of road is part of a loop road that will be extended further to the west to eventually tie back into the Main Campus Drive. Main Campus Drive will then someday be connected into Trailwood Drive. This service road will also serve another area of planned development further to the west of the Alumni Center, This service road will allow access to the parking lot associated with the Alumni Center and will also allow service vehicles to get to the back of the Alumni Center to make deliveries of food, merchandise, etc. The Alumni Center staff requested that the University help with this service drive since the University was also preparing a similar road that would serve the same needs at the Conference and Convention Center. VII. Impact Justification (Avoidance and Minimization) Specifically describe measures taken to avoid the proposed impacts. Response: There were two potential items of impact. Both issues were greatly reduced because of a project redesign. The original idea was to build up the road to a much higher elevation to match the elevation associated with the parking lot and the building footprint. This higher elevation would have required a lot of fill dirt which would have greatly impacted the 50- feet Neuse River Buffer and also the City of Raleigh sanitary sewer and easement. The first impact was that the amount of fill and the toe of the slope would carry well over into the Neuse River Buffer Zones 1 and 2. The second potential impact would have been to the City of Raleigh sewer easement. As was mentioned in an earlier response, the City of Raleigh sewer and easement runs parallel to South Creek. The fill in the toe of the slope would also have carried over into the easement limits. Upon review, the City of Raleigh refused to allow any fill dirt to spill over onto their easement. Therefore, the University decided to reduce the elevation of the road resulting in no fill dirt being placed onto the easement limits of the sanitary sewer pipe. Additionally, this lessens the impacts to the Neuse River Buffer. The idea was submitted to the designer and the final design in enclosed with the application. ?'u?esigncd ?S?ol?'n-?e.,f 7?s 3oS ? S!S The prepft,*4 p}am will impact approximately 24*-SF of Zone 1 and approximately 3,i SF of Zone 2. The total amount of mitigation required for this project is approximately 6.W_5?15,,59R'SF. This obligation will be managed through the University's Mitigation Program. As part of the Program, the University has contracted with Arcadis to design a Stream and Buffer Mitigation Plan for the College of Veterinary Medicine and Lake Wheeler. At this time there are no other constraints associated with the construction or sequencing that may impose limits on work schedules. Additionally, the chart below lays out the seeding schedule for the shoulders, side ditches and slopes, which will be planted with various types of grasses while the east bank will be planted with loblolly pine seedlings. 2 SHOULDERS, SIDE DITCHES, and SLOPES max. 3:1 DATE TYPE PLANTING RATE Au 1 -Nov 1 Tall Fescue 120 lbs/acre Nov 1 -Mar 1 Tall Fescue & Abruzzi Rye 120 lbs/acre & 25 lbs/acre Mar 1 -April 15 Tall Fescue 120 1bs/acre April 15 - June 30 Hulled Common Bermuda Grass 12 lbs/acre July 1 - Aug 15 Tall Fescue AND 120 lbs/acre ***Browntown Millet OR 35 lbs/acre ***Sor hum-Sudan Hybrids 30 lbs/acre SLOPES max 3:1 to 2:1 Mar 1 -Jun 1 Sericer Les edeza (scarified) and 50 lbs/acre Mar 1 - April 15 ADD Tall Fescue 60 lbs/acre Mar 1 - June 30 OR ADD Weeping Lovegrass 5 lbs/acre Mar 1 - June 30 OR ADD Hulled Common Bermuda Grass 8 lbs/acre April 15 - June 30 Hulled Common Bermuda Grass 12 lbs/acre June 1 - Set 1 Tall Fescue AND 60 lbs/acre ***Browntown Millet 35 lbs/acre ***OR Sorghum-Sudan Hubrids 30 lbs/acre Sept 1 - Mar 1 Sericea Les edeza (Unhulled-scarified) 70 lbs/acre AND Tall Fescue 501bs/acre Nov 1 -Mar 1 ADD Abruzzi Rye 25 lbs/acre *** Temporary = Reseed according to optimum season for desired vegetation.

Seed on freshly prepared seedbed and cover seed lightly with seeding equipment or cultipack after seeding. 7. Mulch immediately after seeding and anchor mulch. 8. Inspect all seeded areas and make necessary repairs or reseedings within the planting season if possible. If stand should be over 60% damaged, reestablish following original lime, fertilizer and seeding rates. 9. Consult conservation inspector on maintenance treatment and fertilization after permanent cover is established. *Apply: Agricultural limestone - 2 tons/acre or 3 tons/acre in clay soils Fertilizer - 1,000 lbs/acre (10-10-10) Superphosphate - 500 lbs/acre (20% analysis) Mulch - 2 tons/acre (small grain straw) Anchor - asphalt emulsion @ 300 gals/acre On slopes of the bank, plant loblolly pine seedlings spaced 12" apart along entire east slope of roadway. Seedlings may be purchased from the NC Division of Forest Resources (PH 919.733.2162 or wwwAfr.state.nc.us). Seedlings shall be planted according to NCDFR's recommendations. VIII. Mitigation Briefly describe the proposed mitigation plan. The University has contracted with ARCADIS G&M of North Carolina, Inc. to develop a comprehensive stream and buffer restoration design for two sites on the campus of NC State. One branch is situated on the College of Veterinary Medicine and the other site is located on the Lake Wheeler Research Facility. The chart below lists impacts associated with various University projects and shows both buffer and stream mitigation requirements of the University.

The red wording is optional lingo (don't forget to change the color to black if used or to delete if not used). Also, please change the dollar signs to the appropriate number in the final document. The little gray boxes need to be filled with the appropriate information. Please note the handy dandy titles that Bob inadvertently came up with should be used... Impacts should be specifically listed and specifically referenced. This is necessary to ensure that only the impacts approved are conducted and that if any impacts beyond those specifically approved occur it will be easier to enforce the 401 Cert./Isolated Wetland Permit/Buffer Approval. Taking this extra bit of time now saves headaches later. $$) Impacts Approved ? The following impacts are hereby approved as long as all of the other specific and general conditions are met. No other impacts are approved including incidental impacts: Amount Approved Units Plan Location or Reference Stream feet 404/CAMA Wetlands acres Waters acres , 1 Buffers (square ft.) 14 11 Mitigation may be necessary when mitigation thresholds are exceeded or when certain buffe impacts are conducted. The USACE may require mitigation in certain circumstances that are below our threshold requirements or for the impounded portion of streams for instance when DWQ does not. In those cases we cannot require mitigation. However, when DWQ does require mitigation it is recommended that our requirements be similar to the USACE's. For streams it is anticipated that DWQ will follow the USACE's Stream Mitigation Guidelines. For wetlands we typically require at least 1:1 restoration or creation. The following condition can apply to applicants that propose on site mitigation such as stream relocation where the relocation will meet the definition of stream restoration (i.e. the activity will mitigate for its own impacts). Remember to apply the ratios to the amount of mitigation required. ? Compensatory Mitigation Mitigation must be provided for the proposed impacts as specified in the table below. A final compensatory mitigation plan must be approved in writing by this Office before any of the impacts approved herein are conducted. Additionally, the compensatory mitigation plan must be completely constructed and implemented according to the plans approved by this Office before any permanent building [road] associated with the project is occupied [is opened]. The mitigation must be maintained according to the approved plan and permanently protected by the use of conservation easements or similar protections. Any repairs or adjustments to the mitigation site must be made according to the approved plan or must receive written approval from this Office to make the repairs or adjustments. Compensatory Mitigation Required Stream feet Wetlands acres Waters acres Buffers (square feet The following are recommended In addition to the above when on site stream mitigation, relocation or restoration Is proposed: ? Stream Relocation (Mitigation) with Approved Plans The stream and buffer relocation must be constructed, maintained, and monitored according to the approved plans in the application and application modifications. Any repairs or adjustments to the site must be made according to the approved plans or must receive written approval from this Office to make the repairs or adjustments. ? In order for this project to be used as compensatory mitigation for other specific projects you must obtain written approval from this Office. The request should include the amount of stream length and buffer area credit requested for accounting purposes. Please specify DWQ project No. when making your request. ? Stream Relocation/Stabilization (Mitigation) that Require Additional Approved Plans ?

The stream and buffer relocation must be constructed, maintained, and monitored according to the plans approved by this Office. Any repairs or adjustments to the site must be made according to the approved plans or must receive written approval from this Office to make the repairs or adjustments. The relocated stream must be preserved in perpetuity by use of a conservation easement or other similar mechanism as part of the approved plans. The following mitigation condition can be applied when the applicant has proposed and received approval to use the WRP, EEP, or mitigation bank. Obviously you will have to change references to the WRP If the EEP or a mitigation bank is used. ? Compensatory Mitigation Using the Wetlands Restoration Program (WRP) Mitigation must be provided for the proposed impacts as specified in the table below. We understand that you wish to make a payment to a fund administered by the NC Wetlands Restoration Program (WRP) to meet this mitigation requirement. This has been determined by the DWQ to be a suitable method to meet the mitigation requirement. This contribution will satisfy our compensatory mitigation requirements. Until the WRP receives and clears your check (made payable to: DENR - Wetlands Restoration Program Office), no impacts specified in this Authorization Certificate shall occur. Mr. Ron Ferrell should be contacted at (919) 733-5208 if you have any questions concerning payment into the WRP. You have one month from the date of this approval to make this payment. For accounting purposes, this Authorization Certificate authorizes payment Into the Riparian Buffer Restoration Fund to meet the following compensatory mitigation requirement: Compensatory Mitigation Required River and Subbasin Number Stream feet Wetlands acres Waters acres Buffers (square feet The following condition Is recommended when a stormwater management plan Is required. This typically applies to projects that are over 30% impervious or have concentrated areas of development within a project that are over 30% Impervious. It is recommended that the need for a stormwater management plan be established prior to issuing any approvals. The applicant should also demonstrate that there are adequate space allotted for the proposed BMP and that a BMP appropriate to the stream classification is used (i.e. wetlands, pond with forested filter strip, or bioretention In sensitive watersheds per the GC's). ? Written Stormwater Management Plan (Final Plan Needed) An additional condition is that a final, written stormwater management plan (including a signed and notarized Operation and Maintenance Agreement) shall be approved in writing by this Office before the impacts specified in this Certification occur per Condition No. in GC No. .

Diffuse Flow (Review) An additional condition is that all constructed stormwater conveyance outlets shall be directed to flow in a diffuse manner at non-erosive velocities through the entire protected stream buffers without re-concentrating. If this is not possible it may be necessary to provide stormwater facilities that are considered to remove nitrogen. Additionally, a stormwater management plan for this project shall be provided to this Office before any of the impacts approved herein are conducted. The plan shall specify all stormwater discharge points, plan details, and calculations to indicate that diffuse flow through the protected buffers or nitrogen removal as described above will be achieved. The following are typical conditions added to all approvals unless it does not make sense to add it: ? Certificate of Completion Upon completion of all work approved within the 401 Water Quality Certification or applicable Buffer Rules, and any subsequent modifications, the applicant is required to return the attached certificate of completion to the 401/Wetlands Unit, North Carolina Division of Water Quality, 1650 Mail Service Center, Raleigh, NC, 27699-1650. ? 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 and Authorization Certificate. A sample deed notification can be downloaded from the 401 /Wetlands Unit web site at http://h2o.enr.state.nc.us/ncwetlands. ? Temporary Fills All temporary fill and culverts shall be removed and the impacted area returned to the original grade, including each stream's original cross sectional dimensions, planform pattern, and longitudinal bed and bed profile after construction is complete or within 6 months of the establishment of the crossing, which ever is sooner, and the various sites shall be stabilized with natural woody vegetation (except for the maintenance areas of permanent utility crossings) and restored to prevent erosion; If the crossings are not completely removed and restored as described above within the specified time above, additional written approval from this Office must be obtained to modify this condition. The following are conditions to place specific requirements In areas with protected buffers: ? Protective Fencing The outside buffer, wetland or water boundary and along the construction corridor within these boundaries approved under this authorization shall be clearly marked by orange fabric fencing 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 and GC ? Catawba Buffer Tree Protection No trees shall be removed from Zone 1 of the Catawba Buffer unless they are directly within the construction access corridor. If trees are removed, forested vegetation shall be re-established within the construction access or other temporary impact area occurring in the protected buffer zone within the next growing season following construction of the project; The following are additional conditions for additional sediment and erosion control practices: ? Sensitive Watershed Erosion and Sediment Control Practices The Division of Land Resources' Design Standards in Sensitive Watersheds (15A NCAC 04B .0124) must be adhered to throughout the life of this project. ? NC DOT Sensitive Watershed Erosion and Sediment Control Practices Sediment and erosion control measures shall adhere to the design standards for sensitive watersheds [15A NCAC 4B .0024); see NCDOT publication, Best Management Practices for the Protection of Surface Waters (March 1997); ? Turbidity Standard The turbidity standard of NTUs (Nephelometric Turbidity Units) shall not be exceeded as described in 15 A NCAC 26..0200. Appropriate sediment and erosion control practices must be used to meet this standard. The following are various special conditions for additional protection of various resources. They can be tweaked to meet specific circumstances: ? Culvert Installation The 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 dimensions, pattern, and longitudinal profile) are to be maintained above and below locations of each culvert. The 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-established or, if the pipes installed in a perched manner, the pipes shall be removed and re-installed correctly. The culvert(s) shall not be installed in such a manner that will cause aggradation or erosion of the stream up or down stream of the culvert(s). Existing stream dimensions (including the cross section dimensions, pattern and longitudinal profile) are to be maintained above and below locations of each culvert. As such, it is required that you provide the plans with adequate details that indicate that the current stability of the stream will be maintained or enhanced. You must receive written approval from this Office for the above plans before the culvert(s) is installed. The culvert(s) must be installed according to the approved plans. The establishment of native, woody vegetation and other soft stream bank stabilization techniques must be used where practicable instead of rip rap or other bank hardening methods; If rip-rap is necessary, it shall not be placed in the stream bed, unless specifically approved by the Division of Water Quality. Installation of culverts in wetlands must ensure continuity of water movement and be designed to adequately accommodate high water or flood conditions. Upon completion of the project, the Applicant shall complete and return the enclosed "Certificate of Completion" form to notify NCDWQ when all work included in the §401 Certification has been completed. The responsible party shall complete the attached form and return it to the 401/Wetlands Unit of the NC Division of Water Quality upon completion of the project. Please send photographs upstream and downstream of each culvert site to document correct installation along with the Certificate of Completion form. ? Minimum Release Before any of the impacts approved in the Certification are conducted you must submit, and obtain written approval by this Office for, a minimum water release plan. The plan must include a written explanation of the specific discharge rate and means for each required release. The plan must also include any design specifications, details and calculations to show that the release shall be achieved in the given conditions. The plan shall also include monitoring that ensures compliance. The plan and any associated facilities, once approved, must be in place and implemented upon the completion of ? Marina Projects Any marina project that proposes to dispense or store fuel, shall provide and adhere to an EPA approved SPCC plan to this Office before the fueling facilities are constructed. A completed "Division of Water Quality Use Attainability Analysis for Proposed Marina Projects in Class SA Waters" document must be provided to and must receive written approval from the Regional Office before construction of the proposed project may begin. (Buffer Rules Option) A fifty foot vegetated buffer must be established and maintained around the new perimeter of marina basin. ? "Re-opener" Clause Continuing Compliance. shall conduct its activities in a manner consistent with State water quality standards (including any requirements resulting from compliance with section 303(d) of the Clean Water Act) and any other appropriate requirements of State law and federal law. If DWQ determines that such standards or laws are not being met (including the failure to sustain a designated or achieved use) or that State or federal law is being violated, or that further conditions are necessary to assure compliance, DWQ may reevaluate and modify this certification to include conditions appropriate to assure compliance with such standards and requirements in accordance with 15A NCAC 2H.0507(d). Before modifying the certification, DWQ shall notify and the US Army Corps of Engineers provide public notice in accordance with 15A NCAC 2H.0503 and provide opportunity for public hearing in accordance with 15A NCAC 2H.0504. Any new or revised conditions shall be provided to in writing, shall be provided to the United States Army Corps of Engineers for reference in any permit issued pursuant to Section 404 of the Clean Water Act, and shall also become conditions of the 404 Permit for the project. The following are good for projects approved under GC 3399 (NW 27 and 13): ? Standard Condition for Stream and Wetland Projects Approved Under GC 3399 (no fee paid - no written approval needed) Based on the information provided this Office considers that all of the conditions of General Certification (GC) No. 3353 have been met and that no written approval is required in order to construct the above project.

The construction activities will impact approximately 248 square feet of Zone 1 and approximately 3,170 square feet in Zone 2 of the Neuse River Buffer. As per our phone conversations on May 20 & 22, 2003, it is the University's understanding that the impacts associated with the grading and construction of a fill slope in Zone 2 are considered exempt activities under the Neuse River Buffer Rules (15A NCAC 2B .0233). Additionally, the installation of a temporary sediment and erosion control device in Zone 1 requires written authorization. After construction is complete, the temporary basin will be removed and all disturbed area will be replanted. Additionally, the following information is in response to your letter dated May 8, 2003. 1. Please locate any planned sewer lines on the site plan. The proposed project does not include the installation of sewer lines. An existing sewer line and easement are shown in Exhibit 1 and the Alumni Center Site Plan included in the original application. 2. Please indicate the diffuse flow provision measures on the site plan. The proposed project does not include diffuse flow provision measures for the construction of the service road. Runoff from the construction area will be diverted via a slope drain to a riprap pad. Stormwater runoff from the completed service road will tie into a proposed stormwater management device designed in conjunction with other projects in the area but is not included as part of this application. The pad and slope drain will not impact the buffer and vegetation will be restored in the buffer upon completion of the project. Mr. Bob Zarzecki May 27, 2003 Page 2 3. Are the sanitary sewer lines existing or are they being proposed? The sanitary sewer lines are existing and shown on Exhibit 1 included in the application packet. The application and request for approval is limited only to the construction of the service road. 4. Does the plan have mitigation already built in or is it just a conceptual plan? The Stream and Buffer Conceptual Mitigation Proposal was approved on July 9, 2001 (see attached), DWQ Project No. 01-1032. Currently, the University has contracted with ARCADIS G&M of North Carolina, Inc. to develop a comprehensive stream and buffer restoration plan for two location on the campus of NC State. The design proposes, upon completion, approximately 200,000 square feet of buffer restoration and/or enhancement credit and 600 linear feet of stream restoration, which includes the construction of a constructed wetland. Once again, the University requests written concurrence and authorization to impact the Neuse River buffer for the purpose of constructing the Alumni Center Service Drive.

As per our past conversations, the DWQ has been working on potential rule interpretations to allow for riparian buffer mitigation credit for the preservation of buffers along streams not currently subject to riparian buffer protection. It has been determined through discussions with DWQ and the NC Attorney General's Office staff that this is not currently an option under the existing riparian buffer rules (15A NCAC 2B .0233 and .0242). Therefore, the DWQ can not allow you to count the proposed buffer preservation as identified within the "Mitigation" section of your proposed plan towards your required buffer mitigation. However, the DWQ will be willing to accept the remainder of the stream and buffer mitigation identified within your proposed plan towards existing or future stream or buffer mitigation required by the DWQ for impacts that occur on NCSU property. The acceptance of this mitigation is contingent upon the DWQ approval of design, grading and vegetation plans and Nationwide Permit and Water Quality Certification approvals. The DWQ lead contact person for any stream mitigation or banking will be Mr. John Dorney of the DWQ, 401/Wetlands Certification Unit (Wetlands Unit). He can be contacted at 919-733-9646. Mr. Todd St. John (919-733-9584) and Mr. Bob Zarzecki (919-733-9726) of the Wetlands Unit can also be contacted with any questions related to stream or buffer mitigation. You should also contact the US Army Corps of Engineers (USACE), Raleigh Regulatory Field Office c/o Mr. Ken Jolly (919) 876-8441 for the use of any Nationwide Permits. The proposed mitigation will also have to comply with all other state, federal or local regulations including but not limited to Sediment and Erosion Control.

Please refer to the attached Additional Information Sheet VIII. Mitigation DWQ - In accordance with 15A NCAC 2H .0500, mitigation may be required by tlic NC Division of Water Quality for projects involving greater than or equal to one acre of impacts to freshwater wetlands or greater than or equal to 150 linear feet of total impacts to perennial streams. Page 9 of 12 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.

Page 12 of 12 Additional Information to accompany the Pre-Construction Notification Application III. Project Information 9. Describe the existing conditions on the site and general land use in the vicinity of the project at the time of this application: Response: The land area currently is a heavily wooded tract of land bounded by Lake Raleigh to the north and South Creek to the south. The land has a mixture of pine trees and various species of deciduous trees with small under story. There is a ridgeline located generally in the middle of the land. The topography is gently sloping to the lake and creek. Rainfall runoff flows from this ridgeline either into Lake Raleigh or South Creek. There is an old single lane farm road that runs through the property in a southwest to northeast direction. This farm road can be used but is not very well maintained. The access point is off of Trailwood Drive and goes in behind the Centennial Campus Middle School. The farm road stops at Walnut Creek just behind the darn. A City of Raleigh sewer pipe runs parallel to South Creek on the north side of the creek. This sewer pipe and its easement are issues that must be dealt with in the design of this project. The general land use in this area is undeveloped land in an urban setting. Currently, students and faculty use this land for riding mountain bikes or taking hikes through a wooded area within the City of Raleigh limits. It is not used for farmland or pastureland. 10. Describe the overall project in detail, including the type of equipment to be used: Response: This project will provide a service road for the proposed Alumni Center. The Alumni Center is a proposed $25,000,000 building that is being planned for construction on the ridgeline of the site. This project is in the planning and fund raising stages. The service drive will tie into an access road that will serve for egress to the main entrances to the Alumni Center and to the proposed Conference and Convention Center. This project will prepare a 500 foot roadbed beginning at the access drive and extending to the southwest and oriented somewhat parallel to South Creek. The 500-foot roadbed will be rough graded to the proposed final elevation. The beginning 100 feet of the service drive will be completed with storm drainage features, curb and gutter, 12-inches of ABC, 3-inches of H-binder and 2.5-inches of I-2. A 3' x 3' concrete ductbank containing 8-5" diameter electrical PVC conduits, 3-5" diameter telecommunication PVC conduits, 4-1.5" diameter tetraduct conduits, and 1-2" diameter control conduit will be installed under the road surface. Also, a 12" diameter waterline will be installed under the road surface as well. No gas or sanitary sewer pipes will be installed as part of this project. The Alumni Center will be responsible for installing these two systems when this project is constructed. The type of equipment to be used will be typical grading equipment such as trackhoes, backhoes, dump trucks, sheepsfoots, tamping devices, and steel rollers. 11. Explain the purpose of the proposed work: Response: The purpose of this project is to provide the same sort of accessibility to the Alumni Center side of the Access Road (west) that is being provided for the Conference and Convention Center side (east side). This 500-feet of road is part of a loop road that will be extended further to the west to eventually tie back into the Main Campus Drive. Main Campus Drive will then someday be connected into Trailwood Drive. This service road will also serve another area of planned development further to the west of the Alumni Center. This service road will allow access to the parking lot associated with the Alumni Center and will also allow service vehicles to get to the back of the Alumni Center to make deliveries of food, merchandise, etc. The Alumni Center staff requested that the University help with this service drive since the University was also preparing a similar road that would serve the same needs at the Conference and Convention Center. VII. Impact Justification (Avoidance and Minimization) Specifically describe measures taken to avoid the proposed impacts. Response: There were two potential items of impact. Both issues were greatly reduced because of a project redesign. The original idea was to build up the road to a much higher elevation to match the elevation associated with the parking lot and the building footprint. This higher elevation would have required a lot of fill dirt which would have greatly impacted the 50- feet Neuse River Buffer and also the City of Raleigh sanitary sewer and easement. The first impact was that the amount of fill and the toe of the slope would carry well over into the Neuse River Buffer Zones 1 and 2. The second potential impact would have been to the City of Raleigh sewer easement. As was mentioned in an earlier response, the City of Raleigh sewer and easement runs parallel to South Creek. The fill in the toe of the slope would also have carried over into the easement limits. Upon review, the City of Raleigh refused to allow any fill dirt to spill over onto their easement. Therefore, the University decided to reduce the elevation of the road resulting in no fill dirt being placed onto the easement limits of the sanitary sewer pipe. Additionally, this lessens the impacts to the Neuse River Buffer. The idea was submitted to the designer and the final design in enclosed with the application. The proposed plan will impact approximately 248 SF of Zone 1 and approximately 3,171 SF of Zone 2. The total amount of mitigation required for this project is approximately 5,501 SF. This obligation will be managed through the University's Mitigation Program. As part of the Program, the University has contracted with Arcadis to design a Stream and Buffer Mitigation Plan for the College of Veterinary Medicine and Lake Wheeler. At this time there are no other constraints associated with the construction or sequencing that may impose limits on work schedules. Additionally, the chart below lays out the seeding schedule for the shoulders, side ditches and slopes, which will be planted with various types of grasses while the east bank will be planted with loblolly pine seedlings. 2 SHOULDERS, SIDE DITCHES, and SLOPES max. 3:1 DATE TYPE PLANTING RATE Au 1 -Nov 1 Tall Fescue 120 lbs/acre Nov 1 -Mar I Tall Fescue & Abruzzi Rye 120 lbs/acre & 25 Ibs/acre Mar 1 - April 15 Tall Fescue 120 lbs/acre _April 15 - June 30 Hulled Common Bermuda Grass 12 lbs/acre July 1 - Aug 15 Tall Fescue AND 120 lbs/acre ***Browntown Millet OR 35 lbs/acre ***Sor hum-Sudan Hybrids 30 lbs/acre SLOPES max 3:1 to 2:1 Mar 1 -Jun 1 Sericer Les edeza (scarified) and 50 lbs/acre Mar 1 - April 15 ADD Tall Fescue 601bs/acre Mar I - June 30 OR ADD Weeping Love grass 5 lbs/acre Mar 1 -June 30 OR ADD Hulled Common Bermuda Grass 8 Ibs/acre April 15 - June 30 Hulled Common Bermuda Grass 12 lbs/acre June I - Set 1 Tall Fescue AND 60 lbs/acre ***Browntown Millet 35 lbs/acre ***OR Sorghum-Sudan Hubrids 30 lbs/acre Set 1 - Mar 1 Sericea Lespedeza (Unhulled-scarified) 70 lbs/acre AND Tall Fescue 50 lbs/acre Nov 1 -Mar 1 ADD Abruzzi Rye 25 lbs/acre *** Temporary = Reseed according to optimum season for desired vegetation.

Continue tillage until well-pulverized, firm, reasonably uniform seedbed is prepared 4 to 6 inches deep. 6. Seed on freshly prepared seedbed and cover seed lightly with seeding equipment or cultipack after seeding. 7. Mulch immediately after seeding and anchor mulch. 8. Inspect all seeded areas and make necessary repairs or reseedings within the planting season if possible. If stand should be over 60% damaged, reestablish following original lime, fertilizer and seeding rates. 9. Consult conservation inspector on maintenance treatment and fertilization after permanent cover is established. *Apply: Agricultural limestone - 2 tons/acre or 3 tons/acre in clay soils Fertilizer- 1,000 lbs/acre (10-10-10) Superphosphate - 500 lbs/acre (20% analysis) Mulch - 2 tons/acre (small grain straw) Anchor - asphalt emulsion @ 300 gals/acre On slopes of the bank, plant loblolly pine seedlings spaced 12" apart along entire east slope of roadway. Seedlings may be purchased from the NC Division of Forest Resources (PH 919.733.2162 or www.dfr.state. nc.us). Seedlings shall be planted according to NCDFR's recommendations. VIII. Mitigation Briefly describe the proposed mitigation plan.

Please refer to the attached Additional Infoumation Sheet VIII. Mitigation DWQ - In accordance with 15A NCAC 2H .0500, mitigation may be required by the i4% Division of Water Quality for projects involving greater than or equal to one acre of impacts to freshwater wetlands or greater than or equal to 150 linear feet of total impacts to perennial streams. Page 9of12 USACE - In accordance with the Final Notice of Issuance and Modification of Nationwide Permits, published in the Federal Register on March 9, 2000, mitigation will be required when necessary to ensure that adverse effects to the aquatic environment are minimal. Factors including size and type of proposed impact and function and relative value of the impacted aquatic resource will be considered in determining acceptability of appropriate and practicable mitigation as proposed. Examples of mitigation that may be appropriate and practicable include, but are not limited to: reducing the size of the project; establishing and maintaining wetland and/or upland vegetated buffers to protect open waters such as streams; and replacing losses of aquatic resource functions and values by creating, restoring, enhancing, or preserving similar functions and values, preferable in the same watershed. If mitigation is required for this project, a copy of the mitigation plan must be attached in order for USACE or DWQ to consider the application complete for processing. Any application lacking a required mitigation plan or NCWRP concurrence shall be placed on hold as incomplete. An applicant may also choose to review the current guidelines for stream restoration in DWQ's Draft Technical Guide for Stream Work in North Carolina, available at http-//l12o.enr.state.nc.us/ncwet]ands/strm ide.html. 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. Please see attached Additional Information Sheet 2.

Page 12 of 12 Additional Information to accompany the Pre-Construction Notification Application III. Project Information 9. Describe the existing conditions on the site and general land use in the vicinity of the project at the time of this application: Response: The land area currently is a heavily wooded tract of land bounded by Lake Raleigh to the north and South Creek to the south. The land has a mixture of pine trees and various species of deciduous trees with small under story. There is a ridgeline located generally in the middle of the land. The topography is gently sloping to the lake and creek. Rainfall runoff flows from this ridgeline either into Lake Raleigh or South Creek. There is an old single lane farm road that runs through the property in a southwest to northeast direction. This farm road can be used but is not very well maintained. The access point is off of Trailwood Drive and goes in behind the Centennial Campus Middle School. The farm road stops at Walnut Creek just behind the dam. A City of Raleigh sewer pipe runs parallel to South Creek on the north side of the creek. This sewer pipe and its easement are issues that must be dealt with in the design of this project. The general land use in this area is undeveloped land in an urban setting. Currently, students and faculty use this land for riding mountain bikes or taking hikes through a wooded area within the City of Raleigh limits. It is not used for farmland or pastureland. 10. Describe the overall project in detail, including the type of equipment to be used: Response: This project will provide a service road for the proposed Alumni Center. The Alumni Center is a proposed $25,000,000 building that is being planned for construction on the ridgeline of the site. This project is in the planning and fund raising stages. The service drive will tie into an access road that will serve for egress to the main entrances to the Alumni Center and to the proposed Conference and Convention Center. This project will prepare a 500 foot roadbed beginning at the access drive and extending to the southwest and oriented somewhat parallel to South Creek. The 500-foot roadbed will be rough graded to the proposed final elevation. The beginning 100 feet of the service drive will be completed with storm drainage features, curb and gutter, 12-inches of ABC, 3-inches of H-binder and 2.5-inches of I-2. A 3' x 3' concrete ductbank containing 8-5" diameter electrical PVC conduits, 3-5" diameter telecommunication PVC conduits, 4-1.5" diameter tetraduct conduits, and 1-2" diameter control conduit will be installed under the road surface. Also, a 12" diameter waterline will be installed under the road surface as well. No gas or sanitary sewer pipes will be installed as part of this project. The Alumni Center will be responsible for installing these two systems when this project is constructed. The type of equipment to be used will be typical grading equipment such as trackhoes, backhoes, dump trucks, sheepsfoots, tamping devices, and steel rollers. It. Explain the purpose of the proposed work: Response: The purpose of this project is to provide the same sort of accessibility to the Alumni Center side of the Access Road (west) that is being provided for the Conference and Convention Center side (east side). This 500-feet of road is part of a loop road that will be extended further to the west to eventually tie back into the Main Campus Drive. Main Campus Drive will then someday be connected into Trailwood Drive. This service road will also serve another area of planned development further to the west of the Alumni Center. This service road will allow access to the parking lot associated with the Alumni Center and will also allow service vehicles to get to the back of the Alumni Center to make deliveries of food, merchandise, etc. The Alumni Center staff requested that the University help with this service drive since the University was also preparing a similar road that would serve the same needs at the Conference and Convention Center. VII. Impact Justification (Avoidance and Minimization) Specifically describe measures taken to avoid the proposed impacts. Response: "There were two potential items of impact. Both issues were greatly reduced because of a project redesign. The original idea was to build up the road to a much higher elevation to match the elevation associated with the parking lot and the building footprint. This higher elevation would have required a lot of fill dirt which would have greatly impacted the 50- feet Neuse River Buffer and also the City of Raleigh sanitary sewer and easement. The first impact was that the amount of fill and the toe of the slope would carry well over into the Neuse River Buffer Zones 1 and 2. The second potential impact would have been to the City of Raleigh sewer easement. As was mentioned in an earlier response, the City of Raleigh sewer and easement runs parallel to South Creek. The fill in the toe of the slope would also have carried over into the easement limits. Upon review, the City of Raleigh refused to allow any fill dirt to spill over onto their easement. Therefore, the University decided to reduce the elevation of the road resulting in no fill dirt being placed onto the easement limits of the sanitary sewer pipe. Additionally, this lessens the impacts to the Neuse River Buffer. The idea was submitted to the designer and the final design in enclosed with the application. The proposed plan will impact approximately 248 SF of Zone 1 and approximately 3,171 SF of Zone 2. The total amount of mitigation required for this project is approximately 5,501 SF. This obligation will be managed through the University's Mitigation Program. As part of the Program, the University has contracted with Arcadis to design a Stream and Buffer Mitigation Plan for the College of Veterinary Medicine and Lake Wheeler. At this time there are no other constraints associated with the construction or sequencing that may impose limits on work schedules. Additionally, the chart below lays out the seeding schedule for the shoulders, side ditches and slopes, which will be planted with various types of grasses while the east bank will be planted with loblolly pine seedlings. 2 SHOULDERS, SIDE DITCHES, and SLOPES max. 3:1 DATE TYPE PLANTING RATE Aug 1 -Nov 1 Tall Fescue 120 lbs/acre Nov 1 -Mar 1 Tall Fescue & Abruzzi Rye 120 lbs/acre & 25 lbs/acre Mar 1 - April 15 Tall Fescue 120 lbs/acre April 15 - June 30 Hulled Common Bermuda Grass 12 lbs/acre July 1 - Aug 15 Tall Fescue AND 120 lbs/acre ***Browntown Millet OR 35 lbs/acre ***Sorghum-Sudan Hybrids 30 lbs/acre SLOPES max 3:1 to 2:1 Mar 1 -Jun 1 Sericer Les edeza (scarified) and 50 lbs/acre Mar 1 - April 15 ADD Tall Fescue 60 lbs/acre Mar 1 - June 30 OR ADD Weeping Lovegrass 5 lbs/acre Mar 1 - June 30 OR ADD Hulled Common Bermuda Grass 8 lbs/acre April 15 - June 30 Hulled Common Bermuda Grass 12 lbs/acre June 1 - Set 1 Tall Fescue AND 60 lbs/acre ***Browntown Millet 35 lbs/acre ***OR Sorghum-Sudan Ilubrids 30 lbs/acre Sept 1 - Mar 1 Sericea Lespedeza (Unhulled-scarified) 70 lbs/acre AND Tall Fescue 50 lbs/acre Nov 1 -Mar 1 ADD Abruzzi Rye 25 lbs/acre *** Temporary = Reseed according to optimum season for desired vegetation. Do not allow temporary cover to row over 12" in height before mowing, otherwise fescue may be shaded out. Seedbed Preparation 1. Chisel compacted areas and spread topsoil 3 inches deep over adverse soil conditions, if applicable. 2. Rip the entire area to 6 inches deep. 3. Remove all loose rock, roots, and other obstructions leaving surface reasonably smooth and uniform. 4. Apply agricultural lime, fertilizer and superphosphate uniformly and mix with soil (see below*). 5. Continue tillage until well-pulverized, firm, reasonably uniform seedbed is prepared 4 to 6 inches deep. 6. Seed on freshly prepared seedbed and cover seed lightly with seeding equipment or cultipack after seeding. 7. Mulch immediately after seeding and anchor mulch. 8. Inspect all seeded areas and make necessary repairs or reseedings within the planting season if possible. If stand should be over 60% damaged, reestablish following original lime, fertilizer and seeding rates. 9. Consult conservation inspector on maintenance treatment and fertilization after permanent cover is established. *Apply: Agricultural limestone - 2 tons/acre or 3 tons/acre in clay soils Fertilizer- 1,000 lbs/acre (10-10-10) Superphosphate - 500 lbs/acre (20% analysis) Mulch - 2 tons/acre (small grain straw) Anchor - asphalt emulsion @ 300 gals/acre On slopes of the bank, plant loblolly pine seedlings spaced 12" apart along entire east slope of roadway. Seedlings may be purchased from the NC Division of Forest Resources (PH 919.733.2162 or www.dfnstate.nc.us . Seedlings shall be planted according to NCDFR's recommendations. VIII. Mitigation Briefly describe the proposed mitigation plan. The University has contracted with ARCADIS G&M of North Carolina, Inc. to develop a comprehensive stream and buffer restoration design for two sites on the campus of NC State. One branch is situated on the College of Veterinary Medicine and the other site is located on the Lake Wheeler Research Facility. The chart below lists impacts associated with various University projects and shows both buffer and stream mitigation requirements of the University. Additionally, the chart denotes the approximate credits earned through the CVM and Lake Wheeler restoration projects.
