PROJECT BACKGROUND The subject site is an approximately 50.44-acre mostly undeveloped parcel located on the east side of Bryan Road, south of the intersection with Ackerman Road in Garner, North Carolina. An unnamed tributary of Mahlers Creek intersects Bryan Road and forms the northern and eastern boundary of the project site. The Wake County Public School System is proposing to construct an elementary school on the southern portion of the site. Minimal stream, wetland, and Neuse buffer impacts will result from proposed installations of sewer and water utility lines. Total impacts are below their respective mitigation requirement thresholds. Jurisdictional wetland impacts are located within the existing City of Raleigh sewer easement located on the northern portion of the site. Provided below is a list of pertinent information relating to the site and permit applicant: Applicant: Wake County Public School System Facilities Planning & Construction Management Contact: Mr. Jeff K.

(1964) This site is an approximately 50.44-acre parcel of mostly cleared field with some wooded area. A vacant and dilapidated wood-frame house is located near Bryan Road on the western portion of the site. The adjacent land use includes woodland, residential development, and maintained grassland. An unnamed tributary of Mahlers Creek that crosses Bryan Road forms the northern and eastern property boundary. A residential subdivision (Bingham Station) exists north of the site, beyond two channels of the unnamed tributary. ON-SITE JURISDICTIONAL AREAS MACTEC Engineering and Consulting, Inc. (MACTEC) performed wetland and stream delineations on the subject site on March 12 and 16, 2007. Results of their findings are documented in the attached letter report dated May 3, 2007. A stream assessment was conducted by Lia Myott of NCDENR on August 31, 2007 at S&ME's request to determine the applicability of Neuse buffer rules to on-site streams. A letter dated August 31, 2007 documenting Ms. Myott's findings is attached. S&ME performed additional delineation of wetlands in the vicinity of the existing City of Raleigh sewer easement and met with Mr. James Shern from the USACE on October 31, 2007 to review the wetland delineations and other jurisdictional features on-site. During the meeting between Mr. Shern and John Davis of S&ME, it was indicated that Nationwide Permit No. 12 would be appropriate if all jurisdictional wetland impacts were contained within the permanent City of Raleigh sewer easement. A letter report dated November 6, 2007 documenting the findings of the site meeting with Mr. Shern is attached. In summary, an unnamed tributary of Mahlers Creek forms the northern and eastern property lire of the subject site. At the location of a proposed sewer line crossing, this tributary consists of 401 Certification/Buffer Authorization and Nationwide Permitting S&ME Pro_ject No. ] 054-07-374 E-31 Elementary School -Bryan Road Garner North Carolina April 9, 2008 two channels separated by a distance of approximately 130 feet. Jurisdictional wetlands were identified between and adjacent to the two charnels. PROJECT DESCRIPTION The proposed elementary school location is on the southern portion of the site. A 30-foot construction corridor for the installation of a sewer utility line will run northward from the school and connect to existing utility lines servicing the Bingham Station residential subdivision. The existing sewer line servicing Bingham Station is connected to the City of Raleigh Neuse River Waste Water Treatment Facility. The proposed sewer line installation (having a 30-foot construction corridor) will result in crossing the unnamed tributary (two channels) of Mahlers Creek and impacting riparian wetlands. These impacts are confined to the permanent City of Raleigh sewer easement. A water main proposed to be installed west of the elementary school, also having a 30-foot wide construction corridor, will run northward within the Bryan Road right-of--way and cross the unnamed tributary of Mahlers Creek (one channel) near the street intersection with Ackerman Road. Construction details including profiles are included in this permit application. PROPOSED JURISDICTIONAL IMPACTS The proposed sewer line installation that crosses the northern property line will result in the perpendicular crossing of two channels of the unnamed tributary of Mahlers Creek. The proposed water line installation that connects to an existing water main located near the intersection of Bryan Road and Ackerman Road will also result in the perpendicular crossing of the unnamed tributary of Mahlers Creek (it should be noted that Mahlers Creek comprises only one channel at ibis iocation). Based on 30-fool construction corridors, cumulative impacts equal about 90 linear feet of stream channel. Approximately 0.15 acres of jurisdictional (riparian) wetland and 10,100 square feet (about 0.23 acres) of Neuse buffer will also be impacted. This includes approximately 6,500 square feet of impacts to Zone 1 and approximately 3,600 square feet of impacts to Zone 2. Wetland impacts are confined to the permanent City of Raleigh sewer 40l Certification/Buffer Authorization and Nationwide Permitting S&ME Project No. 1054-07-374 E-31 Elementary School -Bryan Road Garner North Carolina April 9.2008 easement on the northern portion of the site. Impacts are below their respective mitigation requirement thresholds and the proposed maintenance corridor width is 10 feet Each of the perpendicular channel crossings will result in riparian buffer impacts. Additionally, a Zone 2 parallel buffer impact is proposed east of the school. This proposed impact is to the outside portion of Zone 2 and totals approximately 1,100 square feet. It is necessary due to the shape of the parcel, placement of the bio-retention basin on the low side of the site, and the restriction of not being able to place the sewer line under the bio-retention basin. Following the utility line installation, the impacted area will be graded and grass vegetation will be maintained. PROTECTED SPECIES AND CULTURAL RESOURCES S&ME sent scoping letters to the U.S. Fish and Wildlife Service (USFWS) and the North Carolina Natural Heritage Program (NCNI-IP) asking for a review of known occurrences of federally threatened or endangered species on or near the subject site. Also, a scoping letter was sent to the State Historic Preservation Office (SHPO} for a records review of historic sites on or near the subject site. To date, S&ME has received a response from NCNHP stating they have no record of rare species, significant natural communities, significant natural heritage areas, or conservation/managed areas at the site nor within a mile of the project area. AVOIDANCE AND MINIMIZATION The proposed project has been designed to avoid unnecessary impacts. These avoidance measures resulted in minimal proposed impacts to wetlands, riparian buffers, and temporary impacts to waters of the U.S. The utility corridors have been designed to cross the stream at near perpendicular orientations (between 75 and 105 degrees). The proposed maintenance corridor width is 10 feet. 3urisdictional wetland impacts are contained within the permanent City of Raleigh sewer easement. Justification for not using the directional bore technique to install pipe includes: a) the sewer line has to be on lire and on grade and directional boring technique is not accurate enough, and 401 Certification/Buffer Authorization and Nationwide Permitting S&ME Project No. 1054-07-374 E-31 Elementary School - Brvan Road Garner North Carolina April 9, ?008 b) the depth of the water line would need to be deeper far directional bore. Maintenance of the water line and the likelihood of hitting additional rock is a concern. The proposed impact to the outer portion of the Zone 2 riparian buffer east of the school (totaling approximately 1,100 square feet) is necessary due to the shape of the parcel, placement of the bio-retention basin on the low side of the site, and the restriction of not being able to place the sewer line under the bio-retention basin. Following the utility line installation, it is proposed that the impacted area will be graded and grass vegetation will be maintained. REGULATORY CONSIDERATIONS The stormwater management plans are currently being reviewed by the Town of Garner and upon approval will be submitted to DWQ. As part of this permit application, stormwater discharge calculations and a BMP (level spreader) cross-section have been provided to allow confirmation that diffuse flow will be achieved. Appropriate sediment and erosion control practices equaling those outlined in the most recent version of the "North Carolina Sediment and Erosion Control Planning and Design Manual" shall be in full compliance with all specifications governing the proper design, installation, operation and maintenance of such Best Management Practices in order to comply with the appropriate turbidity water quality standard. Impacts have been avoided and minimized, and appropriate measures will be taken during construction to allow flow anal circulation patterns of waters of the U.S. to remain unaffected. MITIGATION Compensatory mitigation may not be required for this project since the impacts are minimal and avoidance and minimization efforts have been undertaken in the planning process. By copy of this correspondence and completed PCN, we are requesting your written concurrence with this 401 riparian buffer authorization and Nationwide Permit No. 12 application. If we can provide additional information or answer questions you may have, please feel free to contact us at (919) 880-3137. 401 Certification/Buffer Authorization and Nationwide Permitting S&ME Project No. 1054-07-374 E-31 Elementary School - Brvan Road Garner North Carolina April 9, 2008 Sincerely, S&ME, Inc. ason Volker Environmental Scientist Lisa J.

The applicant must sign the agent authorization letter. The applicant's name and position must also be spelled out as many signatures are difficult to read. 3. ^ Please provide all of the requested contact information including a fax number and email address. SECTION III -PROJECT INFORMATION The following is the most critical of all the information that you must provide. The quality and detail of the information will often determine the expeditiousness of the review. The following is a checklist of the types of pertinent information required at a minimum: Maps and Plans: ^ The most recent version of the 1:24,000 USGS Topographic Map- Please cleanly delineate the site boundaries, etc. on the map. If the delineation obscures any of the features, it is recommended that a clean copy be provided. Please indicate the quadrangle name. You can go to the USGS web site (http://mac.usgs.gov/maplistsn to verify the most recent version. ^ The most recent version of the NRCS Soil Survey Map - (required for projects within the Neuse River Basin, Tar-Pamlico River Basin, Randleman Lake Watershed and the Catawba River Basin, also recommended for all projects) -Please cleanly delineate the site boundaries, etc. on the map. If the delineation obscures any of the features, it is recommended that a clean copy be provided. Please indicate the page or map number from which the copy of the map was made. Copies of the current soil survey and/or soil survey map sheets can be obtained from the local NRCS County Office (http://www.nc.nres.usda.gov!). GIS soil layers are not acceptable. ^ Vicinity map -Please clearly mark the location and approximate boundaries of the property and project on the map. Please indicate north and scale. Please include applicable road names or State Road numbers. ^ The Site Plan -The most critical map to be provided is the site plan. You must provide full sized plans. The following is the minimum list of plans that are typically needed. ^ Pre-construction/Pre-existing conditions -This sheet must be scaled and include all jurisdictional and non-jurisdictional wetland, stream, water features, State regulated buffers, topographic contours with elevations, approximate extent and nature of forest, field, landscaping, or other cover. Any existing structures and impervious area must be shown. Existing utility lines and easements must be shown. Existing roads, culverts, and other pertinent features must be shown. North arrow and the scale must be shown. Please note that the impact boundaries on the maps should correspond to the flagged impact boundaries in the field. ^ Proposed conditions -These sheets must be scaled and show all existing jurisdictional and non jurisdictional wetland, stream, water features, and State regulated buffers (delineated into Zone 1 and Zone 2) must be underlain on the site plan(s). The plans must show all built-out structures and impervious cover. The plans must include the final grading contours with elevations. The plans must indicate all utilities and easements. It is likely that several versions of the final built- outsite plans will be necessary. ^ Drainage Plans -Final drainage plans must be included. The plans should include the locations and pertinent elevations and sizes of the collection system and drainage ways. All inlets and outlets must also be shown with pertinent elevations. Scaled stormwater BMPs must also be indicated as required by DWQ rules and policies. In certain cases, final stormwater management plans must also be provided, but that will be addressed later in this document. ^ Plats -The plans must show the location and layout of all sub-divided parcels with lot identifications. Platted parcels must be developable without further impacts to jurisdictional and non-jurisdictional wetlands, streams, water features, and State regulated buffers. ^ Proposed Impacts -All impacts to jurisdictional and non jurisdictional wetland, stream, water features, and State regulated buffers must be shown and labeled on the site plans. All excavation, fill, flooding, stabilization, and other impacts that will be conducted in or near jurisdictional and non jurisdictional wetland, stream, water features, and State regulated buffers must be indicated. 4 Wetland Impacts (on the site plan): Precise grading and final elevation contours must be provided. Existing vegetation and any clearing must be specified. ^ All subsurface utility lines must indicate the location of anti-seep collars. Construction detail for anti-seep collars must be provided. ^ Roadway or other crossings of riparian wetlands may require floodway culverts to maintain existing hydrological conditions. ^ When surface drainage features or groundwater recharge areas that feed or would reasonably feed wetlands that are not to be filled are made impervious, it may be necessary to direct some stormwater runoff to those areas in order to maintain hydrology. You must identify these areas and address them. Supporting explanations and discharge information must be provided to show that the wetland would not be eroded or receive too much or too little hydrology. In many cases this could help satisfy part of a stormwater management plan. ^ Flooding ^ Draining Stream Impacts: ^ Stream impacts must be clearly shown on the plans. The centerline as well as the banks of the stream must be surveyed or located by GPS for the portion of the stream to be impacted. Culverting: ^ The inlet and the outlet of the culvert should be aligned with the stream as much as possible. Inlet and outlet elevations and streambed elevations should be indicated. ^ Any widening of the stream must be shown with elevations. ^ The extent of and plan details for all dissipation or grade control devices should be shown with pertinent elevations. ^ For shorter culvert sections, such as for road crossings, a longitudinal cross section that shows the stream bed invert at the inlet and outlet, the existing stream bank elevations and the invert of the inlet and outlet of the pipe(s) must be provided. ^ For shorter culvert sections, such as for road crossings, a vertical cross section must be provided that shows the stream cross section at the inlet and outlet overlain with the culvert and fill cross section. ^ For bottomless culverts or other spans, a vertical cross section should be provided that shows the minimum distance from each span to each stream bank, the stream cross section, the height of the span above the stream and the minimum distance from the edge of each footer to each stream bank. ^ For bottomless culverts or other spans, a plan view must be provided that shows the location of the spans and the stream banks. ^ For longer culverts or culverts that will pass beneath substantial impervious cover, it will be necessary to provide adequate plan detail to show that discharge velocity/energy will be adequately dissipated. ^ Cross section details must be provided showing the provisions for aquatic life passage. Aquatic life passage through culverts is typically achieved by placing the invert of the culvert below the existing bed of the stream per the USACE or North Carolina Wildlife Resource Commission guidelines. Other methods such as baffles may also be used. Please be aware that such placement may require the use of grade/velocity control measures up or down stream of culverts on steeper streams to prevent head-cuts or streambed erosion. The culvert placement relative to the streambed can be indicated on the longitudinal profile. Grade and velocity control measures must be indicated on the plan view and typical designs should be provided. ^ Multiple culverts, wide culverts or sectioned box culverts typically require the use of sills, off-setting or other means to match the cross section of the existing stream (in order to maintain stream stability and provide aquatic life passage). A vertical cross section of the culverts should be shown overlain with the up and downstream stream cross section including the stream flood-prone area. ^ Impacts associated with dam construction must indicate and enumerate all fill associated with the dam footprint, spillway and any bank stream bank stabilization. The length of stream impounded must also be indicated and enumerated. Stream Relocations: ^ Stream relocations must be conducted as specified in General Certification numbers 3402 and 3404 (available on the Wetlands Unit web site). Stream relocation plans must include: ^ Morphological measurements (see Appendix B of the Internal Technical Guide for Stream Work in North Carolina available on the Wetlands Unit web site) -not all of the measurements are applicable in every instance. ^ Typical stream cross sections - Typically, a riffle cross section and a pool cross section that includes the entire flood prone area. The bankfull and flood prone area elevations should be indicated. Similarly, a riffle cross section of the reference stream(s) should be provided. ^ Plan view -Provide scaled plans that show the location of the proposed (preferably with stationing) and the existing stream. In most instances, the bankfull contours and flood prone area contours, in stream structures, bank revetments/stabilization, channel plugs, planting plan, vegetation conditions, stormwater outlets, grade controls, bridges, culverts, sewer lines, roads, fencing, and easement lines should also be provided. ^ Longitudinal Stream Profile - A scaled profile that indicates the thalweg, bankfull, and top of bank elevations should be provided for the design and reference streams. In many cases, it will also be necessary to show the existing land elevations for the design stream. ^ Planting Plan - A planting and/or vegetation management plan should also be provided that makes use of appropriate native vegetation. The plan should indicate the extent, density, and species of plants to be provided. ^ In-stream structure, bank revetment/stabilization, and stormwater outlet typicals - Detailed, typical plans should be provided for all in stream structures, bank revetments or stabilization, and stormwater outlets. The typicals should include materials and specifications as well as relative lengths, positions, and angles. ^ Sediment transport analysis - A sediment transport analysis should be provided based on the current, relevant, accepted practices. The sediment transport analysis should be relevant to the streambed load type and should predict bed load transport equilibrium. ^ Permanent conservation easement or similar means of protection must also be provided. Other Information: ^ 1. The project should always be referred to by this name in all correspondence as well as the DWQ # once it is provided. ^ 2. This only applies to DOT projects, which are not expected to utilize the Express Review Program. ^ 3. This should be the size of the project as identified by the USACE for 404 Permits or by the Division of Water Quality for Buffer Approvals and Isolated Wetland Permits. ^ 4. Please provide the name (as depicted on the USGS topographic map and DWQ Stream Classification Lists) of the nearest water body(ies) to which your project is a tributary to (e.g. "Neuse River (Falls Lake below normal pool elevation)"). (Do not simple state "stream", "river", "ocean", "sound" or "lake'.) Please provide the "stream index number" of the named water body or water body section (e.g. "27-(1)"). Also, please provide the full water quality classification (e.g. "WS-IV NSW CA") of the water body. This information can be obtained from the DWQ web site http://h2o.enr.state. nc. us/bims/Reports/reportsW B. html. ^ 5. Please state which river basin and sub-basin that your project is in (e.g. "Neuse River Basin, NEU01"). This information can be obtained from the DWQ web site http://h2o.enr.state. nc. us/bims/Reports/reportsWB. html. ^ 6. Conditions should also be indicated on the existing site plan where applicable. Photos (including aerial photos) can be helpful in describing the existing conditions. ^ 7. You must provide an attachment that explicitly describes what the proposed project will entail from the planning stage to final construction. ^ 8. This can be a simple explanation, but it is critically important because the purpose dictates how the no practical alternatives are reviewed. SECTION IV -PRIOR PROJECT HISTORY ^ Please include copies of all 401 Water Quality Certifications, Isolated Wetland Permits, Buffer Approvals, USACE Permits, CAMA Permits for the site as well as a copy of the final approved, site plan. SECTION V -FUTURE PROJECT PLANS ^ For projects utilizing the express review process, all impacts both present and potential future must be indicated. For instance, the location or configuration of platted lots sometimes suggests that future impacts will be necessary to build, access, or otherwise develop such lots. Failure to account for such potential impacts could delay or disqualify a project from the rapid review process. If you believe that the lot can be developed without impacts, but you anticipate that your assertion may be questioned, it is recommended that you provide a potential building foot print and/or grading plan to show that future impacts could be avoided. SECTION VI -PROPOSED IMPACTS TO WATER OF THE US ^ 1. It is recommended that the individual impacts be described if there are special things to note about the impacts. Typically the most important thing is to have detailed accurate site plans as described above. Please make sure they are clearly labeled. ^ Please include all proposed temporary impacts. 7 ^ Also, a current, signed delineation map from the USACE should be provided (if available) and a map locating the stream origins signed by the appropriate DWQ Staff must be provided if applicable. ^ 2. Each impact to a wetland must be clearly labeled and identified on the site plan. The type of impact must be clearly stated. If the impact is temporary, a specific plan must be described or shown as to how the wetland will be restored. Keep in mind that the USACE delineates some features as wetlands that DWQ calls streams. Please list any impacts in this table that DWQ would identify as a stream. If there is any doubt, it is recommended that the impacts be listed as streams. Please follow current DWQ policy with respect to whether a stream is perennial or not. It is recommended that you assume that a stream is perennial (unless you are positive that it is not) so if mitigation is required then the appropriate amount of mitigation would be anticipated or requested from the EEP or private bank. If the EEP or private bank has pre- approved too short of an amount of stream or if inadequate mitigation is proposed, then that situation will result in delays. ^ 3. Sometimes it is difficult to determine whether a feature is a modified natural channel or a ditch, especially in the eastern part of the State. Soils, drainage features, topography, macroinvertebrates, and similar factors, all are important for making that determination. ^ 4. Other items to address not specifically requested in the application include downstream sediment starvation, thermal pollution, low flow releases from dams, and aquatic life passage. Other important considerations are buffer reestablishment or mitigation around ponds on buffered streams. The site plan should include the precise elevation contour of the normal pool as well as the dam footprint. Mitigation is required for wetland flooding of an acre or greater and for stream fill (if over the 150 foot threshold) under the dam footprint and any outlet stabilization. SECTION VII -AVOIDANCE AND MINIMIZATION Avoidance and minimization are critical aspects of an application particularly if you desire the application to be processed expeditiously. The following is a checklist of avoidance and minimization questions that DWQ Staff often look for in applications. ^ Are there any stream crossings at angles less than 75° or greater than 105°? ^ Are there any stream crossings that cross two streams above or at the confluence of those streams? ^ Are there any stream, wetland, water, and/or buffer impacts other than perpendicular road crossing near the edges of the property? ^ Can the stream be relocated as a natural channel design as opposed to culverted or otherwise filled? ^ Is any single stream crossed more than once? ^ Can property access routes be moved or reduced to avoid stream, wetland, water, and buffer impacts? ^ Can a building, parking lot, etc. be realigned to avoid impacts? ^ Can the site layout be reconfigured to avoid impacts? ^ Can headwalls or steeper side slopes be used to avoid/minimize impacts? Can a retaining wall be used to avoid/minimize impacts? Can cul de sacs be used in place of a crossing? Can lots be reshaped or have shared driveways to avoid impacts? If based solely on the practicable physical possibility, the answer is "yes" to any of the above questions then you must have to provide substantial and convincing justification as to why the impacts are necessary. If the impacts are required by a local government or other agency, the claim must be supported with appropriate written documentation from the local government or other agency. Most projects typically involve the need to justify avoidance and minimization. If this information is not readily available, then the express review process may not be the appropriate venue to use. Providing alternative plans (such as plans that avoid the impact, minimize the impact and the preferred plan, similar to those used in environmental assessments) and explanations as to why the preferred plan is needed and why the alternative plans won't work are many times helpful in the no practical alternatives review. SECTION VIII -MITIGATION Mitigation for the Express Review Program, final mitigation plans must be presented up front. The final plans (except for plans that propose payment into the Ecosystem Enhancement Program (EEP), Riparian Buffer Restoration Fund, private mitigation banks, or similar banking instruments) must contain detailed plans, specifications, calculations and other supporting data that show that the appropriate mitigation will be achieved at the ratios required. The design plans must be developed to at least the "90%" level. Monitoring plans must be final and specific. Any means of permanent protection, such as a permanent conservation easement must be provided. If you elect to use the EEP or a private mitigation bank, it is recommended that you request the maximum possible mitigation amount that DWQ may require so that you will not have to get further approval from them on short notice. The EEP and private banks are not part of the expedited review process and cannot be expected to meet any such deadlines. There will be no conditional expedited approvals that require final plans at a later date. It is not recommended that innovative mitigation techniques or greater than 10% preservation be requested as part of an expedited process. SECTION IX If your project requires the preparation of an environmental document under NEPA or SEPA and an approval letter has not been issued by the State Clearinghouse, then you cannot apply under the expedited review process. It is your responsibility to find out if such documentation is required. SECTION X There are many aspects of the Buffer Rules that must be addressed in every application, if applicable. The first and most important thing to keep in mind is that allowable activities that require written Approval from DWQ triggers a review of the entire project for compliance with the Buffer Rules. Diffuse Flow & stormwater Management: ^ The most common issues that arise involve the requirement for diffuse flow of stormwater through riparian buffers. Basically one of three things must be indicated in regards to all "new" stormwater that is collected and subsequently discharged. First, provisions for diffuse flow through the protected buffer must be made. This usually involves the use of level spreading devices designed to the latest DWQ guidance on level spreader design, which is available on our web site. Please keep in mind that it does not matter how far a discharge point is from a buffer. The stormwater must be flowing in a diffuse manner at whatever point it eventually reaches the buffer. If the stormwater will not be flowing in a diffuse manner through the protected buffer at the point it reaches the buffer, then one of the following options may be allowed: You may provide a nitrogen removing measure such as a forested filter strip, grassed swale, stormwater wetland, etc. The measure employed should be 9 designed according to the NC DENR Stormwater Best Management Practices Manual or other DWQ Guidance available at http://h2o.enr.state.nc.us/ncwetlands/regcert.html. After the nitrogen is treated, the stormwater can be directly conveyed through the buffer with written DWQ approval. ^ You may discharge the stormwater to an existing man-made conveyance that currently conveys stormwater through the protected buffer (assuming the conveyance was not constructed in violation of the Rules) as long as that conveyance does not need to be altered to convey the flow. Please remember that there are no other choices. The following checklist is intended to help insure that your application will not be deemed incomplete as a result of improper stormwater design. Stormwater Management (for Buffer Rules compliance only -Also, see Section XI): ^ All stormwater out-falls must be clearly shown and labeled on the site plan for projects in Buffered watersheds. List each out-fall as labeled: ^ Option 1: Level spreading devices designed to the latest DWQ Guidance, and devices that merely control velocity but do not provide diffuse flow such as rip rap dissipators are not proposed. List each of these out-falls as labeled on the site plan and provide a DWQ worksheet available at http://h2o.enr.state. nc. us/ncwetlands/regcert. html: ^ Option 2: Nitrogen removing measures designed to DWQ Standards are proposed for discharges for which diffuse flow through a protected Buffer cannot be met. List each of these out-falls as labeled on the site plan and provide a DWQ worksheet available at http://h2o.enr.state.nc.us/ncwetlands/regcert.html ^ Option 3: The stormwater will be discharged to an existing man-made (not including modified natural channels) conveyance that carries the stormwater through the Buffer. The conveyance was not constructed in violation of the Buffer Rules. List each out-fall as labeled: ^ All stormwater out-fall must meet one of the options above. (Note: if you cannot check this box your application will likely not be accepted into the express review process.) Site Plans: ^ All applications on properties with DWQ protected buffers must clearly depict the buffers and any impacts to the buffers on the site plans. The impact maps should clearly depict both zones of the protected buffers and the proposed impact areas (provided in square feet). Surface Water >~ Buffer Delineations: ^ Any surface waters subject to DWQ protected buffers must be field located and accurately depicted on the site plans and impact maps. The width, dimensions and pattern of the surface water must be delineated. The surface water location must not be taken simply from a USGS map, soil survey or local municipality's map. The buffers must be measured from the surface water as required within the applicable buffer protection rule (e.g., all buffers along streams subject to the Neuse and Tar-Pamlico Buffer Rules must be measured from the "top-of-bank" of the stream and not the centerline of the stream). All streams must be surveyed or located by GPS and shown precisely on the site plans. Impact Table: 10 ^ Please provide additional impact tables that clearly state the area of impact for each corresponding impact site. Variances: ^ Projects that require a Major and/or "General" Variance will not be eligible for the use of the Express Review Program (with the exception of the Coastal General "Major" Variance. Mitigation: ^ As opposed to applications that are submitted under our regular process, final mitigation plans must be presented upfront (see requirements for Section VIII above). The mitigation plans must comply with the applicable buffer mitigation rule. SECTION XI - STORMWATER Please provide the following information in regards to potential stormwater requirements: ^ The total acreage of the site. (acres) ^ The total built-out impervious acreage (acres) ^ The total area that will be disturbed (acres) ^ If the total area exceeds 20% imperviousness, the development on the site is uniform in density, and you claim that the total impervious area is less than 30%, you must provide a complete, detailed breakdown of the assumed built-out conditions. The breakdown must be detailed enough to show that all potential impervious areas are accounted for. ^ If there are concentrated areas of development such as multi-family, commercial, cluster, club houses, etc. that exceed 30% imperviousness and the total imperviousness for the site does not exceed 30%, a stormwater management plan will likely be required for those areas that exceed 30% imperviousness. ^ stormwater management plans must be complete with a final design and an executed Operation and Maintenance Agreement. There will be no conditional stormwater approvals for the express review process that allow for approval of the final plans at a later date. Worksheets must be provided that are available at http://h2o.eh n r.state. nc. us/ncwetlands/mitresto. htm I. SECTION XII -SEWAGE DISPOSAL ^ Response must be clear and detailed. Any disposal method that suggests further impacts may be required other than those shown must be clearly addressed on the site plans. SECTION XIII ^ Answering yes to either of these responses automatically precludes you from the express review process. SECTION XIV -SIGNATURE ^ The name, position and/or title of the applicant must be in type or long hand script here with the signature. It should be the same person as described in Part II. If you have any questions about these requirements, please email the Express Review Program at 401 express@ncmail.net and include your question and phone number and the appropriate staff will respond as soon as possible.

Name of project: E-31 Elementary School 2. T.I.P. Project Number or State Project Number (NCDOT Only): Not a NCDOT Project. 3. Property Identification Number: 1629176780 4. Location County: Wake Nearest Town: Garner Subdivision name (include phase/lot number): No subdivisions are proposed. Directions to site (include road numbers/names, landmarks, etc.): The project site (about 50.44 acres) is located on the east side of Bryan Road, south of the intersection with Ackerman Road. An unnamed tributary of Mahlers Creek crosses Bryan Road and forms the northern and eastern boundary of the project site. 5. Site coordinates, if available (UTM or Lat/Long): (For linear projects, such as a road or utility line, attach a sheet that separately lists the coordinates for each crossing of a distinct waterbody.) Project Location: 35.6689 °N, 78.5898 °W 6. Property size (acres): The project area is approximately 50.44 acres. 7. Name of nearest receiving body of water: Unnamed tributary of Mahlers Creek (current classification C; NSW) 8. River Basin: Neuse, NEU02 Subbasin, Stream Index No: 27-43-9 (Note -this must be one of North Carolina's seventeen designated major river basins. The River Basin map is available at http:/lh2o.enr.state.nc.us/admii~/maps/.) Page 6 of 16 Describe the existing conditions on the site and general land use in the vicinity of the project at the time of this application: This site is mostly cleared field with some wooded area. A vacant and dilapidated wood-frame house and shed/pen are located near Bryan Road on the western portion of the site. The adjacent land use includes woodland, residential development, and maintained grassland. An unnamed tributary of Mahlers Creek crosses Bryan road and forms the northern and eastern property boundary. A residential subdivision (Bingham Station) exists north of the site, across two channels of the unnamed tributary. Note that the unnamed tributary is divided into two channels at the location of the proposed sewer line crossing. These buffered channels are separated by a distance of approximately 130 feet. Jurisdictional wetlands were determined to exist between and adjacent to the two channels. 9. Describe the overall project in detail, including the type of equipment to be used: The applicant is pursuing the partial development of the approximately 50.44-acre tract for construction of an elementary school. The school building, parking lot, multi- purpose playing field, and bio-retention basin are proposed to be located on the southern portion of the site. At some time in the future, as part of a separate project, a middle school may be constructed on the northern portion of the site. In order to provide the necessary utility services for the elementary school, an 8-inch sanitary sewer line is proposed to be installed that will run from the proposed school location northward across two channels of the unnamed tributary of Mahlers Creek via the City of Raleigh permanent sewer easement to the existing sewer line servicing the Bingham Station residential subdivision. The two channels of the unnamed tributary are separated by approximately 130 feet of jurisdictional wetland. The crossing of the two channels will be perpendicular. Impacts resulting from the installation of the sewer line are confined within the permanent sewer easement. Approximately 60 linear feet (cumulative) of impacts to these channels are proposed. Impact of approximately 6,000 square feet (cumulative) of riparian buffers associated with the two channels is also proposed. These impacts are based on a 30-foot construction corridor. The existing sewer line that services the Bingham Station subdivision is connected to the City of Raleigh Neuse River Waste Water Treatment Facility. A 12-inch water main is also proposed to be installed. It will run from the school westward to Bryan Road and then northward within the road easement, intersect perpendicularly one channel of the unnamed tributary, and connect to the existing water main near Ackerman Road. The impacts resulting from the installation of the water line will be limited to a riparian buffer impact of about 3,000 square feet (based on a 30-foot construction corridor) and 30 linear feet of impact to the unnamed tributary of Mahlers Creek. Note that the unnamed tributary is a single channel at this location. Another proposed impact will result in approximately 1,100 square feet of Zone 2 Buffer being temporarily impacted east of the school. The extent of this impact has Page 7 of 16 been minimized, but will impact an outside portion of Zone 2. This is necessary due to the shape of the parcel, placement of the bio-retention basin on the low side of the site, and the restriction of not being able to place the sewer line under the bio-retention basin. A total of approximately 10,100 square feet (about 0.23 acres) of Neuse riparian buffer impacts (based on the 30-foot wide construction corridors) is proposed. The utility lines will be installed using heavy equipment and the stream channels will be returned to their original dimensions to the greatest extent practicable when the installations are completed. The proposed Zone 2 Buffer impact of approximately 1,100 square feet east of the school will be graded and grass vegetation will be established and maintained. Maintenance corridors will be limited to a width of 10 feet. A portion of Bryan Road, which borders the western property line, is proposed to be relocated on the site. In total, approximately 9.0 acres of impervious surface is proposed to be constructed on the site. This equals approximately 18% of the total site area. 10. Explain the purpose of the proposed work: The impacts to the unnamed tributary of Mahlers Creek and associated riparian buffer and wetland impacts are necessary in order to provide water and sanitary sewer services to the proposed public elementary school. IV. Prior Project History If jurisdictional determinations and/or permits have been requested and/or obtained for this project (including all prior phases of the same subdivision) in the past, please explain. Include the USACE Action ID Number, DWQ Project Number, application date, and date permits and certifications were issued or withdrawn. Provide photocopies of previously issued permits, certifications or other useful information. Describe previously approved wetland, stream and buffer impacts, along with associated mitigation (where applicable). If this is a NCDOT project, list and describe permits issued for prior segments of the same T.I.P. project, along with construction schedules MACTEC Engineering and Consulting, Inc. (MACTEC) performed wetland and stream delineations on the subject site on March 12 and 16, 2007. Results of their findings are documented in the attached letter report dated May 3, 2007. A stream assessment was conducted by Lia Myott of NCDENR on August 31, 2007 at S&ME's request to determine the applicability of Neuse buffer rules to on-site streams. A letter dated August 31, 2007 documenting Ms. Myott's findings is attached. S&ME performed additional delineation of wetlands in the vicinity of the existing City of Raleigh sewer easement and met with Mr. James Shern from the USACE on October 31, 2007 to review the wetland delineations and other jurisdictional features on-site. A letter report dated November 6, 2007 documenting the findings of the site meeting is attached. Page 8 of 16 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. We do not anticipate that this project will result in future impacts to jurisdictional areas beyond those described in this application, or require additional USACE or DWQ permits. 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 maybe included at the applicant's discretion. If this proposed impact is strictly for wetland or stream mitigation, list and describe the impact in Section VIII below. If additional space is needed for listing or description, please attach a separate sheet. 1. Provide a written description of the proposed impacts: Based on 30-foot construction corridors for the placement of one 8-inch diameter sewer line and one 12-inch diameter water main, the proposed impacts to Waters of the United States total approximately 90 linear feet of stream and 6,750 square feet (about 0.15 acre) of jurisdictional wetland. Proposed jurisdictional wetland impacts are contained within the permanent City of Raleigh sewer easement. The water line will be installed for the most part within the Bryan Road right-of--way but will also cross one channel of the unnamed tributary of Mahlers Creek requiring an impact to that feature. 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. Wetland Impact Type of Wetland Located within Distance to Area of Site Number (indicate on Type of Impact (e.g., forested, marsh, 100-year Nearest Stream Impact (acres) map) herbaceous, bog, etc.) Floodplain (linear feet) (yes/no A permanent forested yes adjacent 0.15 3. List the total acreage (estimated) of all existing wetlands on the property: 1.9 acres Page 9 of 16 4. Individually list all intermittent and perennial stream impacts. Be sure to identify temporary impacts. Stream impacts include, but are not limited to placement of fill or culverts, dam construction, flooding, relocation, stabilization activities (e.g., cement walls, rip-rap, crib walls, gabions, etc.), excavation, ditching/straightening, etc. If stream relocation is proposed, plans and profiles showing the linear footprint for both the original and relocated streams must be included. To calculate acreage, multiply length X width, then divide by 43,560.

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 Impact to Isolated Waters Page 10 of 16 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 VII. No ponds are proposed. Abio-retention basin will be utilized. One 1.48-acre bio-retention basin and another 1.05-acre basin (used as a forebay) are planned for stormwater management on-site. Survey drawings prepared by The Wooten Company illustrating the preliminary layout are attached. The stormwater management plans are currently being reviewed by the Town of Garner. Describe the method of construction (e.g., dam/embankment, excavation, installation of draw-down valve or spillway, etc.): Excavation/embankment - A retaining wall is proposed to be used with the bio-retention basin. Proposed use or purpose of pond (e.g., livestock watering, irrigation, aesthetic, trout pond, local stormwater requirement, etc.): Stormwater management Size of watershed draining to pond: 13.7 acres drain to the bio-retention basin Expected pond surface area: 1.48 acres ofbio-retention basin surface 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 project has been designed to avoid unnecessary impacts. These avoidance measures resulted in minimal proposed impacts to wetlands, riparian buffers, and temporary impacts to waters of the U.S. The utility corridors have been designed to cross the stream at near perpendicular orientations (between 75 and 105 degrees). The proposed maintenance corridor width is 10 feet. Jurisdictional wetland impacts are contained within the existing permanent City of Raleigh sewer easement. The proposed impact to the outside portion of the Zone 2 Buffer (approximately 1,100 square feet) is necessary due to the shape of the parcel, placement of the bio-retention basin on the low side of the site, and the restriction of not being able to place the sewer line under the bio-retention basin. The impacted area will be graded and grass vegetation will be maintained. Page 11 of 16 Justification for not using the directional bore technique to install pipe includes: a) The sewer line has to be on line and on grade and directional boring technique is not accurate enough, and b) the depth of the water line would need to be deeper for directional bore. Maintenance of the water line and the likelihood of hitting additional rock is a concern. 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. USAGE - 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, 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 USAGE 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/stnngide.html. 1. Provide a brief description of the proposed mitigation plan. The description should provide as much information as possible, including, but not limited to: site location (attach directions and/or map, if offsite), affected stream and river basin, type and amount (acreage/linear feet) of mitigation proposed (restoration, enhancement, creation, or preservation), a plan view, preservation mechanism (e.g., deed restrictions, conservation easement, etc.), and a description of the current site conditions and proposed method of construction. Please attach a separate sheet if more space is needed. Impacts have been avoided and minimized to the extent practicable. Appropriate mitigation for the proposed project includes avoidance and minimization procedures implemented during the design phase of the proposed project. We do not anticipate that our client will be required to provide additional compensatory mitigation since avoidance and minimization efforts have been undertaken in the planning process. Temporary impacts are limited to 901inear feet of stream channel. Approximately 0.15 acre of jurisdictional wetland will also be Page 12 of 16 impacted. Jurisdictional wetland impact is located within the permanent City of Raleigh sewer easement on the northern portion of the site. The unavoidable wetland impacts are all adjacent to the unnamed tributary of Mahlers Creek. Stream and wetland impacts are below their respective thresholds, above which require mitigation. Maintenance corridors will be 10 feet wide. In addition, impacts to the Neuse riparian buffers are limited to approximately 10,100 square feet (about 0.23 acre) and it is our understanding that the activity is allowable without mitigation based on a review of the Table of Uses in 15A NCAC 02B .0233 (6). 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 willing 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): None Amount of buffer mitigation requested (square feet): None Amount of Riparian wetland mitigation requested (acres): None Amount ofNon-riparian wetland mitigation requested (acres): None Amount of Coastal wetland mitigation requested (acres): None IX. Environmental Documentation (required by DWQ) 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)? 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. Page 13 of 16 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 ^ Meuse Riparian Buffers 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. Zone* Impact (s uare feet Multiplier Required Mitigation 1 6,500 ----- ----- 2 3,600 ----- ----- Total 10,100 * 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. Based on 15A NCAC 2B .0233 and the calculated acreages, mitigation threshold are not exceeded and therefore no buffer mitigation is anticipated. 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 Stormwater plans are currently in review by the Town of Garner. Approximately 9.0 acres of impervious area (about 18% of the total area of the site) is proposed for construction of the elementary school and relocation of a portion of Bryan Road. One 1.48-acre bio-retention pond and another 1.05-acre basin (used as a forebay to the bio- retention pond) are planned for stormwater management on-site. The total watershed area (including the bio-retention and forebay basin) equals about 13.7 acres. Survey drawings prepared by The Wooten Company illustrating a preliminary layout (currently in review by The Town of Garner) are attached. A level spreader device will be used to discharge diffuse flow to the existing washout near the receiving stream. Flow calculations and across-section diagram of the proposed device are included in this application package. The detailed description provided by McNeely Associates P.A. is as follows: Page 14 of 16 It is our intention to provide a distribution box at the Bioretention outlet location. Each side of the box will have 12" diameter outlets at invert elevation of 272.00 (bottom of level spreader). The lip elevation of the level spreader will be at 273.00. The length of the level spreader will be based on the Ql routed flow out of the basin of 0.65 cfs. This will be 65 feet X 0.65 = 42.25 feet minimum total (22 feet each side of box will be used). An over flow 15" RCP pipe from the box will be set at elevation 273.15 and empty through a 15" FES onto arip-rap apron sized for the routed Q10 of 5.7 cfs. We will then use a 20 feet wide pyramat lined trapezoidal grassed channel (1.91 fps velocity per attached calculation) for approximately 65 feet to carry the Q10 safely to an existing washout near the stream. We will filUline the washout with 30" deep NCDOT Class 1 Rip-rap to convey the water safely into the stream without further washout or stream bank erosion. 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.

(MACTEC) is pleased to submit this report concerning the preliminary detennination of waters of the U.S. and Neuse Riparian Buffer Rule applicability on a 54.2 acre undeveloped parcel (Subject Property). This report documents the methodology used to assess approximate boundaries of jurisdictianal waters of the U.S. and Neuse Riparian Buffer Rule applicability, the results of our studies, and a summary of potential. permitting requirements under Section 404 of the Clean Water Act (33 U.S.C. 1344) and Section 15 of the North Carolina Administrative Code {15A NCAC 028.0233), also known as the Neuse Buffer Rules. Background and Methodolagy The 54.2 acre subject property is located south of the intersection of Ackerman Road with Bryan Road in Wake County, Garner, North Carolina (Figure l). The subject property is currently undeveloped, anal surrounding land use adjacent to the subject property includes wooded land, residential development and maintained grassland (Figure 2}. A delineation of waters of the U.S., including wetlands, was conducted within the boundaries of the subject property. Jurisdictional waters of the United States such as ponds, streams, and wetlands are defined by 33 CFR 328.3(b) and are protected by Section 404 of the Clean Water Act (33 U.S.C. 1344), which is administered and enforced in North Carolina by the U.S. Army Corps of Engineers (USAGE}, Wilmington District. 1iAC'I'EC Engineering and Consulting, [nc. 3301 Atiaatic Avenue • Raleigh, NC 27604 • Phone: 919.876.0416 Pax: 919.83 L8136 W W W. ~ttdC tGC. COt7t Bryan Property rt1ACTEC Project Na.: 6470-07-1720 GVaters of tl~e U.S Delineation May 3, 2007 GVake County, North Carolina Page 2 Jurisdictional wetlands are defined in the field as areas that have positive evidence of three environmental parameters: • Hydrophytic vegetation (vegetation typically adapted for life in saturated soil conditions), • Wetland hydrology (substrate that is inundated or saturated to the surface at some time during the growing season.), • Hydric soils (soils that possess characteristics that are associated with reducing/anaerobic soil conditions). The Neuse Buffer Rules, administered by the North Carolina Department of Environment and Natural Resource (NCDENR), Division of Water Qttality {DWQ), protect the first 50 feet of riparian buffer adjacent to surface waters (intermittent/perenniai streams, lakes, and ponds) in the Neuse River Basin "that are approximately shown on the most recent version of either the USGS 7.5 minute quadrangle topographic map or the NRCS. Soil Survey". The three stream ratings are generally defined as follows: • Ephemeral stream: a drainage feature that carries stonnwater in direct response to precipitation, • intermittent stream: a well-defined channel that may contain water for only part of the year, and • Perennial stream: awell-defined channel that contains water year round during a year of normal rainfall. Wetlands observed within the subject property were delineated using the Routine On-Site Determination Method as defined in the Cbrps of Engineers Wetlands Delineation Manual. Observations of soils, vegetation, and hydrology were made in order to delineate the appropriate wetland/upland boundaries. Previously-mapped stream channels observed within the subject property were delineated in accordance with the stream evaluation protocols described in DWQ's Identification Methods for the Origins of Intermittent and Perennial Streanzs~,Yersion 3.1 (DWG 1Llethvdj, dated February 28, 2005. The DWQ Method is a qualitative anal quantitative assessment of channel characteristics (i.e., biological, hydrological., and geomorphological components) for the purpose of documenting ephemeral (non- jurisdictional) versus intermittent or perennial channels (potentially jurisdictional).

A stream reach is classified as perennial if the total score is greater than or equal to 30 on the SIF. There are certain cases where a stream may receive a score of less than 30 points but be classified as perennial if particular biological indicators are present such as .fish, crayfish, amphibians, clams, or specific families of benthic macroinvertebrates. Delineated wetland and stream. boundaries were approximated based on mapped landscape features and a limited amount of GPS data points. Wetland polygons and stream segments were generated, digitized, and overlaid on Wake County 2005 aerial photography and NCDOT 2-foot elevation contours. Approximate location information provided i.n this document is intended for preliminary planning purposes only. Prior to fieldwork, the following references were reviewed to identify potential locations of waters of the U.S.. 1) United States Geological Survey (USGS) 7.5-minute Garner, N.C.

They select large, super-canopy roost trees that are open and accessible, and prefer live pines or cypress. The subject property does not contain suitable forested area to support populations of bald eagles. Habitat for the red-cockaded woodpecker (RCW) is generally associated with open and mature stands of longleaf pine (Picots palustris) or other species of living southern pines encompassing 80-125 acres. RCW's require open stands of pine containing trees 60 years old and older for nestinglroosting habitat, and prefer stands of living pine trees 30 years old and older for foraging habitat. The subject property does not contain the appropriate trees or suitable forested area to attract anal support nesting or foraging RC W's. Habitat for Dwarf wedgemussel (Alasmidonta heterodon) is generally associated with large rivers and small streams with mixed substrates. This bivalve prefers streams situated in apredominantly-wooded landscape with intact riparian buffers and good water quality. The subject property is not situated in a wooded landscape and therefore is unlikely to support populations of Dwarf wedgemussel. Habitat for Michaux's sumac {Rhus michauxii) is generally associated with sandy, loamy swales and rocky open woods. Miehaux's sumac survives best in areas where some form of disturbance has provided an open area, but this plant has low reproductive capacity.

Regulatory Consideradons/Development Implications Depending on the type and extent of waters of the U.S. {streams, ponds, and wetlands) to be impacted, Section 404 permitting requirements can range from activities that are considered exempt or preauthorized, to those requiring pre-construction notification (PCN) for a Nationwide Permit (NWP) or activities requiring a Section 404 Individual Permit (IP) from the USACE. The completion of a PCN for a NWP would require a discussion of the project's purpose and need, measures taken to avoid/minimize impacts, wetland mitigation strategies, and the likelihood of having to address stone-water management. Following PCN submittal, the USACE District Engineer (DE) must determine if the PCN is complete (within 30 days of the date of receipt). The prospective permtttee shall not begin the proposed activity anti[ notified in writing by the DE that the activity may proceed under the NWP; or unless 45 days have passed from the DE's receipt of the complete notification {including a Section 441 WQC), and the prospective pernittee has not received written notice from the DE. Limited impacts of up to 1/2 acre to waters of the U.S., including wetlands, and up to 300 linear feet of stream bed associated with the construction or expansion of commercial and institutional buildings, including attendant features, may be authorized under N WP No. 39. Under N WP No. 39, any impacts of waters of the U.S. will require the submittal of a PCN to the USACE. [n addition to a delineation of the jurisdictional waters of the U.S. for the subject site, the submittal ofa PCN under NWP No. 39 may require that the following concerns be addressed: presence of protected species, presence of significant cultural resources, and mitigation planning to off-sot losses to jurisdictional waters. Impacts allowable under NWP No. 39 will also require notification to the North Carolina Division of Water Quality (DWQ). ]mpacts to surface waters (streams and ponds} that appear on the most recent version of the USGS 7.5 Minute Topographic Map and/or NRCS Soil Survey (Stream I) may also be subject to the Neuse River Basin Riparian Buffer Rules. These regulations require a 50-foot vegetated buffer around previously-mapped intermittent/perennial strea-ns, lakes and ponds. In addition, where notification to the DWQ is required, compensatory mitigation will likely be required by the DWQ for impacts to perennial streams and/or jurisdictional wetlands. Compensatory mitigation at a one-to-one ratio may be required. for wetland impacts exceeding I/10 acre. Bryan Property MACTEC Project t~'o.: 6970-07-1720 Waters of the U.S Delineation May 3, 2007 Wake Co:tnty, North Carolina Page 1 D Compensatory mitigation may be required for impacts to surface waters (streams and ponds) based on the discretion of the USACE DE. Activities conducted under the Nationwide Permit program must comply with the USACE NWP General Conditions, USACE NWP Regional Conditions, and DWQ General Conditions. Permitting under Section 404 of the Clean Water Act may require coordination with interested agencies including, but not limited to, the USACE, the DWQ, the North Carolina Department of Cultural Resources (NCDCR), the U.S. Fish and Wildlife Service (USFWS), and the U.S. Environmental Protection Agency (USEPA). if jurisdictional areas to be impacted exceed I/2 acre of wetlands, and/or 300 If of stream providing important aquatic function, then a Section 404 Lndividual Permit ([P) would likely be required for the proposed development. The 1P process involves a rigorous documentation procedure and will require addressing protected species and culturaE resources issues, an alternatives analysis, wetland impact avoidance and minimization strategies, and compensatory wetland mitigation. The IP process typically includes a 30-day public notice period with an additional extended review schedule by the agencies. Based on MACTEC's experience, it is not uncommon for the processing and approval of an 1P applEcation to require six months or more. Recommendations If future development within the subject property is considered, MACTEC recommends that a jurisdictional delineation, survey, and USACE veri.fcation be conducted of potential streams and wetlands identifed as part of this waters of the U.S. determination. MACTEC also recommends a DWQ stream verification be conducted to determine if any surface waters can be removed from Neuse Buffer Ruie applicability (i.e., mapped Stream 2), or if an.y development activities may be considered "allowable" or "exempt" within fifty feet ofpreviously-mapped Stream 1 and Pond 1. The USACE verification will provide appropriate documentation for McDonald-York, Inc. concerning the area of jurisdictional waters of the U.S. located within the subject property. An overlay of proposed site plans on USACE-verified jurisdictional boundaries will allow an approximation of impacts and subsequent determination of permitting requirements. MACTEC recommends th.e completion of these activities prior to any mechanized land clearing or other disturbance in proximity to potential waters of the U.S. MACTEC further recommends that impacts to USACE-verified jurisdictional waters of the U.S. on site be avoided and/or minimized to the extent practicable. Depending on th e extent of proposed impacts to certain jurisdictional areas on the subject site, a permit may be required from the USACE, along with a 401.

Young Reference: E-31 Elem School Site USACE Meeting Report S&ME Project No. 1054-07-374 Mr. John Davis with S&ME, Inc. and Mr. Amin Davis with MACTEC met with Mr. James Shern from the U.S. Army Corps of Engineers (USACE) on October 31, 2007 to review the wetland delineation on the above referenced site. At this meeting, the USACE reviewed MACTEC's jurisdictional delineation of the school site and S&ME's jurisdictional delineation of the existing City of Raleigh public sewer easement. The USACE conducted a field review of the jurisdictional features delineated by MACTEC and found that wetland areas W2, W4, and WS located adjacent and abutting tributary S1 are jurisdictiona1404 wetlands. Wetland areas W 1, W3 and W6 located in the drainage ways on the site are not jurisdictional because they do not meet all three of the wetland criteria described in the 1987 Wetland Delineation Manual. See Figure 4 for location of these areas. Feature S1 was determined to be a jurisdictional feature that is classified as a relatively permanent water (RPW) tributary with important aquatic functions. Tributary S 1 flows into Mahler's Creek which flows into Swift Creek which flows into the Neuse River. Feature S2 was determined to be a jurisdictional RPW tributary with a point of origin approximately 60 feet from the convergence with tributary S 1. See Figure 4. This point of origin is the same point that the NCDWQ determined to be a buffered stream. Mr. Shern said that tributary S2 does not have significant aquatic function. S&ME, itvC. / 3201 Spring Forest Road /Raleigh, NC 27616 / p 919.872.2660 f 919.876.3958 / www.smeinc.com E31 Elem School Site S&ME Project No. 1054-07-374 Garner N C. November 6 2007 S&ME flagged the jurisdictional features in an approximate 80-foot wide corridor in the genera] vicinity of the City of Raleigh's 30-foot sewer easement. The sewer easement has not been flagged on the site and actual location within this 80-foot wide area is yet to be determined. The USACE reviewed the jurisdictional features in this area and concurred with the delineation. This area contains two RPW tributaries and adjacent abutting wetlands. See Figure 1 for approximate location of these areas. The surveyors may use this figure to locate the boundaries of the wetlands and tributaries. Permitting details were discussed with the USACE and if the only jurisdictional impacts for this site are in the existing sewer easement that a nationwide permit 12 could be used for the sewer impacts. For permitting purposes, the following information will need to be obtained as the project progresses. • Size and placement depth of the proposed sewer pipe. • Proposed and future facilities that the sewer will serve. • Name of treatment plant for the proposed sewer pipe. • Justification for not utilizing the directional bore technique to install sewer pipe. • Details about sewer easement construction width and maintenance width. • Construction details of sewer maintenance road, if any, that shows no above grade fill including gravel Other permitting items discussed at the meeting include mitigation of impacts. The width of the maintenance corridor will be used to calculated wetland mitigation areas. Also, the preservation of a tree canopy over the sewer easement will help reduce mitigation requirements. In summary the areas W 1, W3, and W6 are not jurisdictional and may be used for storm water devices or filled for buildings, parking etc. Mr. Shern indicted that obtaining a jurisdictional determination report from the USACE maybe delayed and Mr. Shern mentioned that it may be quicker to obtain a nationwide permit from his office than obtain the jurisdictional determination report. Also, please forward Figure 1 and Figure X to the surveyors so they can locate the approved wetland flags on the site and in the vicinity of the sewer easement. Also, the engineers will need to be aware of the sewer details for our permitting documents.

MACTEC'S WETLAND FLAG NUMBERS I've attached a map we originally created after our delineation in April. Since the USACE is not claiming jurisdiction on W1, W3, & W6 per our meeting with Jamie Shern on Wednesday, 1 did not include flag numbers for these wetlands. We did not flag the NRCS-mapped stream immediately north of W1, but the coordinates where DWQ rated the stream as intermittent are 35.6656/- 78.5877.

Ross Jr., Secretary The Natural Heritage Program has no record of rare species, significant natural communities, significant natural heritage areas, or conservation managed areas at the site nor within a mile of the project area. Although our maps do not show records of such natural heritage elements in the project area, it does not necessarily mean that they are not present. It may simply mean that the area has not been surveyed. The use of Natural Heritage Program data should not be substituted for actual field surveys, particularly if the project area contains suitable habitat for rare species, significant natural communities, or priority natural areas. You may wish. to check the Natural Heritage Program database website at www.ncnhp.org for a listing of rare plants ~tnd animals and significant natural communities in the county and on the quad map. Our Program also has a new website that allows users to obtain information on element occurrences and significant natural. heritage areas within two miles of a given location: <http://nhpweb.enr.state.Haas/nhis/public/gmap75_main.phtml>. The user name is "public" and the password is "heritage". You may want to click "Help" for more information. NC OneMap now provides digital Natural Heritage data online for free. This service provides site specific information on GIS Layers with Natural•Heritage Program rare species occurrences and Significant Natural Heritage Areas.. The NC OneMap website provides Element. Occurrence (EO) ID numbers (instead of species name), and the data user is then encouraged to contact the Natural Heritage Program for detailed information.. This sei~~i:;e a3lz~ws the acct to quickly arid- efficiently gtt-site specftc NHP data without visitirig the NHP workroom or waiting for.the Information Request to be answered by NHP staff. For more information about data formats and access, visit <www.ncaneman.com>, then click on "FTP Data Download", and then "nheo.zip" [to the right of "Natural Heritage Element Occurrences"] You may also e-mail NC OneMap at <dataq_nncmaiLnet> for more information.
