The proposed total permanent impacts to jurisdictional waters are 0.128 acres and therefore the project is eligible for authorization under an NWP 29: The proposed project consists of the construction of a 46-lot single-family detached residential subdivision and associated infrastructure (roads, sidewalks, open recreational space, utilities, stormwater management, etc.). The proposed Greenhawk - Vinci subdivision consists of a ±65.73-acre site located on one parcel (Parcel #: 0646087028) located at 6524 Burt Road, Fuquay Varina, Wake County (Lat: 35.584853°N; -78.863739°W). The project site will eventually be annexed into Fuquay-Varina. The project is in the Cape Fear River basin (HUC: 03030004) and onsite waters drain to Buckhorn Creek. The Water Quality Classification for Buckhorn Creek is: C and the Stream Index Number Proposed Impact Table Feature Type of Impact Impact Area LF SF AC Stream Permanent (Functional Loss) 216 1,804 0.041 Stream Temporary 26 146 0.004 Stream Totals - Wetland Permanent - 3,796 0.087 Wetland Totals - 3,796 0.087 Proposed Permanent Impact Table Type of Impact Impact Area LF AC Wetland – Permanent - 0.087 Stream – Permanent (Functional Loss) 216 0.041 Total 216 0.128 Greenhawk - Vinci Tract Fuquay-Varina, Wake Co. NWP 29 PCN Submittal Page 2 of 4 is: 18-7-(1). The project is located in the Cape Fear River Basin (outside Jordan Lake watershed) and therefore is not subject to state-regulated riparian buffers. Proposed Project The purpose of the proposed project is to construct a single-family detached residential subdivision to meet the existing and growing demand for residential housing in Wake County. The project consists of the following: • 46 single family home lots • Construction of infrastructure (roads, greenways, open space, utilities, stormwater management, etc.) • Breaching the dam of Pond 2 to permanently drain it. The proposed design will result in one stream crossing. Dublin Creek Drive will cross Stream 2 perpendicularly with a 154’x72” culvert. This crossing is necessary to tie into the existing Dublin Creek Drive stub in the adjacent development. A riprap dissipator will be constructed below the culvert to dissipate flow velocity to prevent erosion and sedimentation of the stream. The proposed road will tie into an existing stub road on the opposite side of Stream 2. Project History WithersRavenel (WR) conducted a delineation of the wetlands and streams in April 2023. WR submitted a Preliminary Jurisdictional Determination Request on 10/23/2023. Proposed Impacts The proposed impacts consist of: • 216 lf (0.041 acres) of permanent functional loss stream impacts • 26 lf (0.003 acres) of temporary stream impacts • 0.087 acres of permanent wetland impacts All proposed impacts are necessary for the installation of the Dublin Creek Drive crossing over Stream 2 (perennial). The proposed Dublin Creek drive crossing is necessary to provide one of the two entrances to the site. The other road entrance, Meadow Walk Drive will tie into an existing stub road to the south. Dublin Creek Drive has been designed to cross Stream 2 perpendicularly using a 154’x72” culvert. The culvert will be buried 12” below the stream bed. 216 linear feet of permanent stream impacts (Impacts S2 & S3) with functional loss are proposed for the crossing. Impact S2 is for the culvert and Impact S3 is to realign 14 linear feet of stream channel to align with the proposed culvert and downstream channel. Additionally, 0.087 acres of permanent wetland impacts (Impacts W1 & W2) are proposed at this crossing. The proposed crossing features DOT standard headwalls. A riprap dissipator will be installed below the culvert to prevent erosion and sedimentation of downstream waters. The riprap will be installed by burying the riprap such that the top of the riprap matches the pre-construction contours of the natural stream bed, allowing for the passage of aquatic life and preventing a loss of function of stream channel. The proposed activities also include breaching the dam of Pond 2 to permanently drain it. All breaching activities and sediment & erosion control measures will be contained within the footprint of the dam and no wetland, stream or open water impacts are necessary for breaching Pond 2. Greenhawk - Vinci Tract Fuquay-Varina, Wake Co. NWP 29 PCN Submittal Page 3 of 4 During construction of the culverted road crossing, work will be completed “in the dry” by constructing temporary coffer dams upstream and downstream of the culverts within the impact areas and pumping flow around the construction area. 26 linear feet of temporary stream impacts (Impacts S1 & S4)) are proposed for construction of the crossing. Upon completion of construction, all temporarily impacted streams will be restored to pre- construction contours and the banks will be stabilized using a biodegradable matting and seeded with a riparian seed mix. No matting will be placed on the stream beds. Avoidance and Minimization Prior to site plan design, the applicant requested that a detailed delineation be conducted so that impacts to wetlands and “waters” could be minimized. Proposed permanent impacts for construction of the subdivision and infrastructure have been minimized to only those necessary for construction of one road crossing to access developable uplands within the site and tie into an existing stub road. There are no impacts proposed for construction lots, utilities, stormwater management, or greenways. The road crossing has been designed to cross wetlands and stream perpendicularly at the narrowest points to minimize impacts. Impacts to Stream 2 are unavoidable because of the need to tie into an existing stub road to the east for a second road entrance to the site. An existing pond, streams, and wetlands cross the entire eastern side of the site therefore avoiding impacts entirely was not feasible. The proposed Dublin Creek Drive crossing was designed to cross partially within a gap between Wetlands G and F to avoid impacts. The confluence of Streams 1 and 2 are located in this area, however the crossing was designed to avoid this area to minimize impacts while still lining up with the stub road. A riprap dissipator will be constructed at the proposed crossing such that the riprap will be installed by burying to match the pre-construction contours of the natural stream bed, allowing for the passage of aquatic life, and preventing a loss of function. DOT standard headwalls are proposed at the crossing to reduce fill slope helping to minimize stream impacts. Upon completion of construction, all temporarily impacted streams will be restored to pre- construction conditions and grades, and temporarily stabilized with biodegradable matting and seeded with a riparian seed mix. No matting will be placed on the stream bed. Access during construction will occur within uplands. Additionally, sediment and erosion control measures will be installed prior to construction. Mitigation Stream Mitigation The current proposal will result in 216 lf (0.041 acres) of permanent stream impacts with functional loss. Because the proposed total permanent stream impacts with functional loss exceed 0.02 acres, the applicant proposes compensatory mitigation for permanent stream impacts at a 2:1 ratio resulting in the need to obtain 432 lf of stream mitigation credits. WR contacted mitigation banks that service the 03030004 HUC to inquire about the availability of stream mitigation credits. Insufficient stream credits are available from private mitigation banks. A Letter of Acceptance from NCDMS is attached for 432 linear feet of stream mitigation credits. Greenhawk - Vinci Tract Fuquay-Varina, Wake Co. NWP 29 PCN Submittal Page 4 of 4 Wetland Mitigation The current proposal will result in 0.087 acres of permanent wetland impacts. Because the proposed total permanent wetland impacts are below 0.1 acres, the applicant does not propose to provide compensatory mitigation for permanent wetland impacts. Stormwater Management Plan Because the project is a low-density development (under 15% total site impervious) stormwater will be conveyed via roadside ditches that discharge to vegetated conveyances. The stormwater management plan will be reviewed and approved by Fuquay-Varina as the certified local municipality.

The primary information used to generate this list is the known or expected range of each species. Additional areas of inuence (AOI) for species are also considered. An AOI includes areas outside of the species range if the species could be indirectly aected by activities in that area (e.g., placing a dam upstream of a sh population even if that sh does not occur at the dam site, may indirectly impact the species by reducing or eliminating water ow downstream). Because species can move, and site conditions can change, the species on this list are not guaranteed to be found on or near the project area. To fully determine any potential eects to species, additional site-specic and project-specic information is often required. Section 7 of the Endangered Species Act requires Federal agencies to "request of the Secretary information whether any species which is listed or proposed to be listed may be present in the area of such proposed action" for any project that is conducted, permitted, funded, or licensed by any Federal agency. A letter from the local oce and a species list which fullls this requirement can only be obtained by requesting an ocial species list from either the Regulatory Review section in IPaC (see directions below) or from the local eld oce directly.

BREEDING SEASON Probability of Presence Summary The graphs below provide our best understanding of when birds of concern are most likely to be present in your project area. This information can be used to tailor and schedule your project activities to avoid or minimize impacts to birds. Please make sure you read "Supplemental Information on Migratory Birds and Eagles", specically the FAQ section titled "Proper Interpretation and Use of Your Migratory Bird Report" before using or attempting to interpret this report. Probability of Presence () Each green bar represents the bird's relative probability of presence in the 10km grid cell(s) your project overlaps during a particular week of the year. (A year is represented as 12 4- week months.) A taller bar indicates a higher probability of species presence. The survey eort (see below) can be used to establish a level of condence in the presence score. One can have higher condence in the presence score if the corresponding survey eort is also high. How is the probability of presence score calculated? The calculation is done in three steps: 1. The probability of presence for each week is calculated as the number of survey events in the week where the species was detected divided by the total number of survey events for that week. For example, if in week 12 there were 20 survey events and the Spotted Towhee was found in 5 of them, the probability of presence of the Spotted Towhee in week 12 is 0.25. 2. To properly present the pattern of presence across the year, the relative probability of presence is calculated. This is the probability of presence divided by the maximum probability of presence across all weeks. For example, imagine the probability of presence in week 20 for the Spotted Towhee is 0.05, and that the probability of presence at week 12 (0.25) is the maximum of any week of the year. The relative probability of presence on week 12 is 0.25/0.25 = 1; at week 20 it is 0.05/0.25 = 0.2. 3. The relative probability of presence calculated in the previous step undergoes a statistical conversion so that all possible values fall between 0 and 10, inclusive.

To see a bar's probability of presence score, simply hover your mouse cursor over the bar. Breeding Season () Yellow bars denote a very liberal estimate of the time-frame inside which the bird breeds across its entire range. If there are no yellow bars shown for a bird, it does not breed in your project area. Survey Eort () Vertical black lines superimposed on probability of presence bars indicate the number of surveys performed for that species in the 10km grid cell(s) your project area overlaps. The number of surveys is expressed as a range, for example, 33 to 64 surveys. To see a bar's survey eort range, simply hover your mouse cursor over the bar. No Data () A week is marked as having no data if there were no survey events for that week. Survey Timeframe Surveys from only the last 10 years are used in order to ensure delivery of currently relevant information.

(A year is represented as 12 4- week months.) A taller bar indicates a higher probability of species presence. The survey eort (see below) can be used to establish a level of condence in the presence score. One can have higher condence in the presence score if the corresponding survey eort is also high. How is the probability of presence score calculated? The calculation is done in three steps: 1. The probability of presence for each week is calculated as the number of survey events in the week where the species was detected divided by the total number of survey events for that week. For example, if in week 12 there were 20 survey events and the Spotted Towhee was found in 5 of them, the probability of presence of the Spotted Towhee in week 12 is 0.25. Prairie Warbler Dendroica discolor This is a Bird of Conservation Concern (BCC) throughout its range in the continental USA and Alaska. Breeds May 1 to Jul 31 Prothonotary Warbler Protonotaria citrea This is a Bird of Conservation Concern (BCC) throughout its range in the continental USA and Alaska. Breeds Apr 1 to Jul 31 Red-headed Woodpecker Melanerpes erythrocephalus This is a Bird of Conservation Concern (BCC) throughout its range in the continental USA and Alaska. Breeds May 10 to Sep 10 Rusty Blackbird Euphagus carolinus This is a Bird of Conservation Concern (BCC) only in particular Bird Conservation Regions (BCRs) in the continental USA Breeds elsewhere Wood Thrush Hylocichla mustelina This is a Bird of Conservation Concern (BCC) throughout its range in the continental USA and Alaska.

To properly present the pattern of presence across the year, the relative probability of presence is calculated. This is the probability of presence divided by the maximum probability of presence across all weeks. For example, imagine the probability of presence in week 20 for the Spotted Towhee is 0.05, and that the probability of presence at week 12 (0.25) is the maximum of any week of the year. The relative probability of presence on week 12 is 0.25/0.25 = 1; at week 20 it is 0.05/0.25 = 0.2. 3. The relative probability of presence calculated in the previous step undergoes a statistical conversion so that all possible values fall between 0 and 10, inclusive. This is the probability of presence score. To see a bar's probability of presence score, simply hover your mouse cursor over the bar. Breeding Season () Yellow bars denote a very liberal estimate of the time-frame inside which the bird breeds across its entire range. If there are no yellow bars shown for a bird, it does not breed in your project area. Survey Eort () Vertical black lines superimposed on probability of presence bars indicate the number of surveys performed for that species in the 10km grid cell(s) your project area overlaps. The number of surveys is expressed as a range, for example, 33 to 64 surveys. To see a bar's survey eort range, simply hover your mouse cursor over the bar. No Data () A week is marked as having no data if there were no survey events for that week. Survey Timeframe Surveys from only the last 10 years are used in order to ensure delivery of currently relevant information. The exception to this is areas o the Atlantic coast, where bird returns are based on all years of available data, since data in these areas is currently much more sparse.

Nationwide Conservation Measures describes measures that can help avoid and minimize impacts to all birds at any location year round. Implementation of these measures is particularly important when birds are most likely to occur in the project area. When birds may be breeding in the area, identifying the locations of any active nests and avoiding their destruction is a very helpful impact minimization measure. To see when birds are most likely to occur and be breeding in your project area, view the Probability of Presence Summary. Additional measures or permits may be advisable depending on the type of activity you are conducting and the type of infrastructure or bird species present on your project site. What does IPaC use to generate the list of migratory birds that potentially occur in my specied location? The Migratory Bird Resource List is comprised of USFWS Birds of Conservation Concern (BCC) and other species that may warrant special attention in your project location. The migratory bird list generated for your project is derived from data provided by the Avian Knowledge Network (AKN). The AKN data is based on a growing collection of survey, banding, and citizen science datasets and is queried and ltered to return a list of those birds reported as occurring in the 10km grid cell(s) which your project intersects, and that have been identied as warranting special attention because they are a BCC species in that area, an eagle (Eagle Act requirements may apply), or a species that has a particular vulnerability to oshore activities or development. 1/26/24, 11:33 AM IPaC: Explore Location resources https://ipac.ecosphere.fws.gov/location/LRSEKVT6BZCR3GHZB4KA436DP4/resources 13/16 Again, the Migratory Bird Resource list includes only a subset of birds that may occur in your project area. It is not representative of all birds that may occur in your project area. To get a list of all birds potentially present in your project area, please visit the Rapid Avian Information Locator (RAIL) Tool. What does IPaC use to generate the probability of presence graphs for the migratory birds potentially occurring in my specied location? The probability of presence graphs associated with your migratory bird list are based on data provided by the Avian Knowledge Network (AKN). This data is derived from a growing collection of survey, banding, and citizen science datasets. Probability of presence data is continuously being updated as new and better information becomes available. To learn more about how the probability of presence graphs are produced and how to interpret them, go the Probability of Presence Summary and then click on the "Tell me about these graphs" link. How do I know if a bird is breeding, wintering or migrating in my area? To see what part of a particular bird's range your project area falls within (i.e. breeding, wintering, migrating or year-round), you may query your location using the RAIL Tool and look at the range maps provided for birds in your area at the bottom of the proles provided for each bird in your results. If a bird on your migratory bird species list has a breeding season associated with it, if that bird does occur in your project area, there may be nests present at some point within the timeframe specied. If "Breeds elsewhere" is indicated, then the bird likely does not breed in your project area. What are the levels of concern for migratory birds? Migratory birds delivered through IPaC fall into the following distinct categories of concern: 1. "BCC Rangewide" birds are Birds of Conservation Concern (BCC) that are of concern throughout their range anywhere within the USA (including Hawaii, the Pacic Islands, Puerto Rico, and the Virgin Islands); 2. "BCC - BCR" birds are BCCs that are of concern only in particular Bird Conservation Regions (BCRs) in the continental USA; and 3. "Non-BCC - Vulnerable" birds are not BCC species in your project area, but appear on your list either because of the Eagle Act requirements (for eagles) or (for non-eagles) potential susceptibilities in oshore areas from certain types of development or activities (e.g. oshore energy development or longline shing). Although it is important to try to avoid and minimize impacts to all birds, eorts should be made, in particular, to avoid and minimize impacts to the birds on this list, especially eagles and BCC species of rangewide concern. For more information on conservation measures you can implement to help avoid and minimize migratory bird impacts and requirements for eagles, please see the FAQs for these topics. Details about birds that are potentially aected by oshore projects For additional details about the relative occurrence and abundance of both individual bird species and groups of bird species within your project area o the Atlantic Coast, please visit the Northeast Ocean Data Portal. The Portal also oers data and information about other taxa besides birds that may be helpful to you in your project review. Alternately, you may download the bird model results les underlying the portal maps through the NOAA NCCOS Integrative Statistical Modeling and Predictive Mapping of Marine Bird Distributions and Abundance on the Atlantic Outer Continental Shelf project webpage. 1/26/24, 11:33 AM IPaC: Explore Location resources https://ipac.ecosphere.fws.gov/location/LRSEKVT6BZCR3GHZB4KA436DP4/resources 14/16 Bird tracking data can also provide additional details about occurrence and habitat use throughout the year, including migration. Models relying on survey data may not include this information. For additional information on marine bird tracking data, see the Diving Bird Study and the nanotag studies or contact Caleb Spiegel or Pam Loring. What if I have eagles on my list? If your project has the potential to disturb or kill eagles, you may need to obtain a permit to avoid violating the Eagle Act should such impacts occur. Proper Interpretation and Use of Your Migratory Bird Report The migratory bird list generated is not a list of all birds in your project area, only a subset of birds of priority concern. To learn more about how your list is generated, and see options for identifying what other birds may be in your project area, please see the FAQ "What does IPaC use to generate the migratory birds potentially occurring in my specied location". Please be aware this report provides the "probability of presence" of birds within the 10 km grid cell(s) that overlap your project; not your exact project footprint. On the graphs provided, please also look carefully at the survey eort (indicated by the black vertical bar) and for the existence of the "no data" indicator (a red horizontal bar). A high survey eort is the key component. If the survey eort is high, then the probability of presence score can be viewed as more dependable. In contrast, a low survey eort bar or no data bar means a lack of data and, therefore, a lack of certainty about presence of the species. This list is not perfect; it is simply a starting point for identifying what birds of concern have the potential to be in your project area, when they might be there, and if they might be breeding (which means nests might be present). The list helps you know what to look for to conrm presence, and helps guide you in knowing when to implement conservation measures to avoid or minimize potential impacts from your project activities, should presence be conrmed. To learn more about conservation measures, visit the FAQ "Tell me about conservation measures I can implement to avoid or minimize impacts to migratory birds" at the bottom of your migratory bird trust resources page.

Wetlands in the National Wetlands Inventory (NWI) Impacts to NWI wetlands and other aquatic habitats may be subject to regulation under Section 404 of the Clean Water Act, or other State/Federal statutes. For more information please contact the Regulatory Program of the local U.S. Army Corps of Engineers District. Please note that the NWI data being shown may be out of date. We are currently working to update our NWI data set. We recommend you verify these results with a site visit to determine the actual extent of wetlands on site. This location overlaps the following wetlands: NOTE: This initial screening does not replace an on-site delineation to determine whether wetlands occur. Additional information on the NWI data is provided below. Data limitations The Service's objective of mapping wetlands and deepwater habitats is to produce reconnaissance level information on the location, type and size of these resources. The maps are prepared from the analysis of high altitude imagery. Wetlands are identied based on vegetation, visible hydrology and geography. A margin of error is inherent in the use of imagery; thus, detailed on-the-ground inspection of any particular site may result in revision of the wetland boundaries or classication established through image analysis.

Metadata should be consulted to determine the date of the source imagery used and any mapping problems. Wetlands or other mapped features may have changed since the date of the imagery or eld work. There may be occasional dierences in polygon boundaries or classications between the information depicted on the map and the actual conditions on site. Data exclusions Certain wetland habitats are excluded from the National mapping program because of the limitations of aerial imagery as the primary data source used to detect wetlands. These habitats include seagrasses or submerged aquatic vegetation that are found in the intertidal and subtidal zones of estuaries and nearshore coastal waters. Some deepwater reef communities (coral or tubercid worm reefs) have also been excluded from the inventory. These habitats, because of their depth, go undetected by aerial imagery. Data precautions Federal, state, and local regulatory agencies with jurisdiction over wetlands may dene and describe wetlands in a dierent manner than that used in this inventory. There is no attempt, in either the design or products of this inventory, to dene the limits of proprietary jurisdiction of any Federal, state, or local government or to establish the geographical scope of the regulatory programs of government agencies. Persons intending to engage in activities involving modications within or adjacent to wetland areas should seek the advice of appropriate Federal, state, or local agencies concerning specied agency regulatory programs and proprietary jurisdictions that may aect such activities.

NCNHP PROJECT REPORT 1/12/2024 NCNHDE-24726 January 26, 2024 Troy Beasley Withers & Ravenel 115 MacKenan Drive Cary, NC 27511 RE: Vinci Tract; 02211491.00 Dear Troy Beasley: The North Carolina Natural Heritage Program (NCNHP) appreciates the opportunity to provide information about natural heritage resources for the project referenced above. Based on the project area mapped with your request, a query of the NCNHP database indicates that there are no records for rare species, important natural communities, natural areas, and/or conservation/managed areas within the proposed project boundary. Please note that although there may be no documentation of natural heritage elements within the project boundary, it does not imply or confirm their absence; the area may not have been surveyed. The results of this query should not be substituted for field surveys where suitable habitat exists. In the event that rare species are found within the project area, please contact the NCNHP so that we may update our records. The attached ‘Potential Occurrences’ table summarizes rare species and natural communities that have been documented within a one-mile radius of the property boundary. The proximity of these records suggests that these natural heritage elements may potentially be present in the project area if suitable habitat exists. Tables of natural areas and conservation/managed areas within a one-mile radius of the project area, if any, are also included in this report. If a Federally-listed species is found within the project area or is indicated within a one-mile radius of the project area, the NCNHP recommends contacting the US Fish and Wildlife Service (USFWS) for guidance. Contact information for USFWS offices in North Carolina is found here: https://www.fws.gov/offices/Directory/ListOffices.cfm?statecode=37. Please note that natural heritage element data are maintained for the purposes of conservation planning, project review, and scientific research, and are not intended for use as the primary criteria for regulatory decisions. Information provided by the NCNHP database may not be published without prior written notification to the NCNHP, and the NCNHP must be credited as an information source in these publications.
