Indicate Which of the Following Apply: A. Preliminary Determination ® There appear to be waters, including wetlands on the above described project area/property, that may be subject to Section 404 of the Clean Water Act (CWA)(33 USC § 1344) and/or Section 10 of the Rivers and Harbors Act (RHA) (33 USC § 403). The waters, including wetlands have been delineated, and the delineation has been verified by the Corps to be sufficiently accurate and reliable. The approximate boundaries of these waters are shown on the enclosed delineation map dated 4/7/2022. Therefore this preliminary jurisdiction determination may be used in the permit evaluation process, including determining compensatory mitigation. For purposes of computation of impacts, compensatory mitigation requirements, and other resource protection measures, a permit decision made on the basis of a preliminary JD will treat all waters and wetlands that would be affected in any way by the permitted activity on the site as if they are jurisdictional waters of the U. S. This preliminary determination is not an appealable action under the Regulatory Program Administrative Appeal Process (Reference 33 CFR Part 331). However, you may request an approved JD, which is an appealable action, by contacting the Corps district for further instruction. ❑ There appear to be waters, including wetlands on the above described project area/property, that may be subject to Section 404 of the Clean Water Act (CWA)(33 USC § 1344) and/or Section 10 of the Rivers and Harbors Act (RHA) (33 USC § 403). However, since the waters, including wetlands have not been properly delineated, this preliminary jurisdiction determination may not be used in the permit evaluation process. Without a verified wetland delineation, this preliminary determination is merely an effective presumption of CWA/RHA jurisdiction over all of the waters, including wetlands at the project area, which is not sufficiently accurate and reliable to support an enforceable permit decision. We recommend that you have the waters, including wetlands on your project area/property delineated. As the Corps may not be able to accomplish this wetland delineation in a timely manner, you may wish to obtain a consultant to conduct a delineation that can be verified by the Corps. B. Approved Determination ❑ There are Navigable Waters of the United States within the above described project area/property subject to the permit requirements of Section 10 of the Rivers and Harbors Act (RHA) (33 USC § 403) and Section 404 of the Clean Water Act (CWA)(33 USC § 1344). Unless there is a change in law or our published regulations, this determination may be relied upon for a period not to exceed five years from the date of this notification. ❑ There are waters, including wetlandson the above described project area/property subject to the permit requirements of Section 404 of the Clean Water Act (CWA) (33 USC § 1344). Unless there is a change in the law or our published regulations, this determination may be relied upon for a period not to exceed five years from the date of this notification. ❑ We recommend you have the waters, including wetlands on your project area/property delineated. As the Corps may not be able to accomplish this wetland delineation in a timely manner, you may wish to obtain a consultant to conduct a delineation that can be verified by the Corps. ❑ The waters, including wetlands on your project area/property have been delineated and the delineation has been verified by the Corps. The approximate boundaries of these waters are shown on the enclosed delineation map dated DATE. We strongly suggest you have this delineation surveyed. Upon completion, this survey should be reviewed and verified by the Corps. Once SAW-2022-01007 verified, this survey will provide an accurate depiction of all areas subject to CWA jurisdiction on your property which, provided there is no change in the law or our published regulations, may be relied upon for a period not to exceed five years. ❑ The waters, including wetlands have been delineated and surveyed and are accurately depicted on the plat signed by the Corps Regulatory Official identified below onDATE. Unless there is a change in the law or our published regulations, this determination may be relied upon for a period not to exceed five years from the date of this notification. ❑ There are no waters of the U.S., to include wetlands, present on the above described project area/property which are subject to the permit requirements of Section 404 of the Clean Water Act (33 USC 1344). Unless there is a change in the law or our published regulations, this determination may be relied upon for a period not to exceed five years from the date of this notification. ❑ The property is located in one of the 20 Coastal Counties subject to regulation under the Coastal Area Management Act (CAMA). You should contact the Division of Coastal Management in Morehead City, NC, at (252) 808-2808 to determine their requirements. Placement of dredged or fill material within waters of the US, including wetlands, without a Department of the Army permit may constitute a violation of Section 301 of the Clean Water Act (33 USC § 1311). Placement of dredged or fill material, construction or placement of structures, or work within navigable waters of the United States without a Department of the Army permit may constitute a violation of Sections 9 and/or 10 of the Rivers and Harbors Act (33 USC § 401 and/or 403). If you have any questions regarding this determination and/or the Corps regulatory program, please contact James Lastinger at 919-554-4884 ext 32 or James.C.Lastinger(dusace. armv.mil. C. Basis For Determination: Basis For Determination: See the preliminary jurisdictional determination form dated 07/07/2022. D. Remarks: E. Attention USDA Program Participants This delineation/determination has been conducted to identify the limits of Corps' Clean Water Act jurisdiction for the particular site identified in this request. The delineation/determination may not be valid for the wetland conservation provisions of the Food Security Act of 1985. If you or your tenant are USDA Program participants, or anticipate participation in USDA programs, you should request a certified wetland determination from the local office of the Natural Resources Conservation Service, prior to starting work.

The Corps of Engineers believes that there may be jurisdictional aquatic resources in the review area, and the requestor of this PJD is hereby advised of his or her option to request and obtain an approved 7D (AID) for that review area based on an informed decision after having discussed the various types of 7Ds and their characteristics and circumstances when they may be appropriate. 2. In any circumstance where a permit applicant obtains an individual permit, or a Nationwide General Permit (NWP) or other general permit verification requiring "pre- construction notification" (PCN), or requests verification for a non -reporting NWP or other general permit, and the permit applicant has not requested an AID for the activity, the permit applicant is hereby made aware that: (1) the permit applicant has elected to seek a permit authorization based on a PJD, which does not make an official determination of jurisdictional aquatic resources; (2) the applicant has the option to request an AID before accepting the terms and conditions of the permit authorization, and that basing a permit authorization on an AID could possibly result in less compensatory mitigation being required or different special conditions; (3) the applicant has the right to request an individual permit rather than accepting the terms and conditions of the NWP or other general permit authorization; (4) the applicant can accept a permit authorization and thereby agree to comply with all the terms and conditions of that permit, including whatever mitigation requirements the Corps has determined to be necessary; (5) undertaking any activity in reliance upon the subject permit authorization without requesting an AID constitutes the applicant's acceptance of the use of the PJD; (6) accepting a permit authorization (e.g., signing a proffered individual permit) or undertaking any activity in reliance on any form of Corps permit authorization based on a PJD constitutes agreement that all aquatic resources in the review area affected in any way by that activity will be treated as jurisdictional, and waives any challenge to such jurisdiction in any administrative or judicial compliance or enforcement action, or in any administrative appeal or in any Federal court; and (7) whether the applicant elects to use either an AID or a PJD, the 7D will be processed as soon as practicable. Further, an AID, a proffered individual permit (and all terms and conditions contained therein), or individual permit denial can be administratively appealed pursuant to 33 C.F.R. Part 331. If, during an administrative appeal, it becomes appropriate to make an official determination whether geographic jurisdiction exists over aquatic resources in the review area, or to provide an official delineation of jurisdictional aquatic resources in the review area, the Corps will provide an AID to accomplish that result, as soon as is practicable. This PJD finds that there "may be"waters of the U.S. and/or that there "may be" navigable waters of the U.S. on the subj ect review area, and identifies all aquatic features in the review area that could be affected by the proposed activity, based on the following information: SUPPORTING DATA.

Good Afternoon Morgan, Unfortunately, we do not have any mitigation banks within the Cape Fear 03 at this time. However, we are anticipating having credits potentially late 2023/early 2024. For now I would recommend reaching out to another private mitigation bank but feel free to reach back out once the approvals have been issued to see if we do have the credits by then.

ROY COOPER Governor ELIZABETH S. BISER Secretary MARC RECKTENWALD Director Chris Raughley Pulte Home Company 1225 Crescent Green Drive, Suite 250 Cary, NC 27518 Project: Westford NORTH CAROLINA Environmental Quafiry July 26, 2023 Expiration of Acceptance: 1/26/2024 County: Lee The purpose of this letter is to notify you that the NCDEQ Division of Mitigation Services (DMS) is willing to accept payment for compensatory mitigation for impacts associated with the above referenced project as indicated in the table below. Please note that this decision does not assure that participation in the DMS in - lieu fee mitigation program will be approved by the permit issuing agencies as mitigation for project impacts. It is the responsibility of the applicant to contact permitting agencies to determine if payment to the DMS will be approved. You must also comply with all other state, federal or local government permits, regulations or authorizations associated with the proposed activity including G.S. § 143-214.11. This acceptance is valid for six months from the date of this letter and is not transferable. If we have not received a copy of the issued 404 Permit/401 Certification within this time frame, this acceptance will expire. It is the applicant's responsibility to send copies of the permits to DMS. Once DMS receives a copy of the permit(s) an invoice will be issued based on the required mitigation in that permit and payment must be made prior to conducting the authorized work. The amount of the in -lieu fee to be paid by an applicant is calculated based upon the Fee Schedule and policies listed on the DMS website.

ROBERTSON -- Assess. Manage. Consult. January 21, 2022 Mr. Bob Anderson VP of Land Acquisition — Raleigh Division Pulte Group 1225 Crescent Green Drive, Suite 250 Cary, North Carolina 27518 Email: Bob.Anderson@PulteGroup.com Re: Review of Historic Resources and Protected Species Carthage Street Site 1715 Carthage Street Sanford, Lee County, North Carolina F&R Project: 59Z-0459 Mr. Anderson: Froehling & Robertson, Inc., (F&R) presents herein the results of the informal historical resources and protected species review conducted at the above -mentioned site. SUMMARY The following is a summary of our findings and is not intended to replace more detailed information contained elsewhere in this report. F&R reviewed information at the North Carolina State Historic Preservation Office (SHPO) and submitted a Request for Comments (RFC) letter to SHPO. The RFC letter included basic project information and documentation of F&R's information review. SHPO responded with "no comment on the project as proposed" and "are aware of no historic resources which would be affected by the project". Additionally, F&R reviewed information from the North Carolina Department of Environmental Quality — Natural Heritage Program (NC NHP) and the U.S. Fish and Wildlife Service (USFWS) in order to determine if protected species are likely to be affected. Based on a review of the NHP response letter and the USFWS Information for Planning and Consultation (IPaC) official species list for the project site, three federally protected species have been identified that may occur in the proposed project location. However, critical habitat was not identified within the project area and F&R's field observations did not identify obvious suitable habitat for the identified species. Based upon this information, it appears that the proposed project is not likely to adversely affect federally or state listed threatened and endangered species or their designated critical habitats. PURPOSE The purpose of the Historical Resources Review was to gain an understanding of what historic, cultural, and/or archeological resources as protected by the National Historic Preservation Act are present within the immediate vicinity of the project site. The purpose of the Protected (threatened & endangered) Species review was to gain an understanding of what biological resources as protected by the state and federal A Minority -Owned Business Endangered Species Acts are present within the immediate vicinity of the project site. The purpose of the North Carolina Natural Heritage Program (NCNHP) review is to gain an understanding of the records for rare species, important natural communities, natural areas, and/or conservation or managed areas within the project boundary. PROJECT SITE According to Client -provided information, the Property is located along the east side of Carthage Street, just south of the intersection with Gloucester Drive in Sanford, Lee County, North Carolina. The Property consists of an irregular -shaped parcel of land containing 47.77 acres and identified by Lee County PIN 9641-09-5617- 00. The Property consists primarily of wooded land, with some cleared land visible on the western portion. The central and western portions of the Property appear to have formerly been agricultural land and currently consists of planted pines. Remnants of a residence and two barns are also located at the Property. A stream is also depicted on the eastern portion of the Property. The Property is bordered to the north by Gloucester Drive and wooded and single-family residential land; to the east by a residential subdivision; to the south by residential and wooded land and a pond; and to the west by Carthage Street, beyond which is single-family residential development and wooded land. A property topographic map adapted from the USGS 7.5 Minute Topographic Quadrangle Map "Sanford, NC" dated 2019 is included as Figure 2 in the attachments. SCOPE OF WORK The informal rare & endangered species and historical resources review was conducted in general accordance with F&R's Proposal No. 2159-00797, dated November 11, 2021. INFORMAL SURVEY HISTORIC RESOURCES REVIEW F&R visited the SHPO GIS Website to review the most current information. Based on F&R's review of 7.5 — Minute USGS Topographic Quadrangle Map and the supporting literature available at the SHPO GIS website, sites listed on the National Register (NR) or the Study List (SL) for the NR were not identified on the project site nor determined eligible for listing (DOE) on the National Register of Historic Places. However, the Buffalo Rural Historic District (LE0788), listed on the Study List and has been determined eligible, was identified approximately 800 feet north of the Property. The Spence Kelley Farm (LE0688) was also identified on the Study List approximately 1,300 feet north of the project site. One Surveyed Only, Gone site (Hornady House — LE0702) was identified within 1,500 feet of the Property. Furthermore, sites listed on the NR were not identified within 1,500 feet of the Property. F&R sent a Request for Comments (RFC) Letter to SHPO. The letter included the above project information and the results of F&R's review. SHPO responded to the RFC with a letter dated January 20, 2022. SHPO responded with comments indicating they are unaware of historic resources that would be affected by the project and therefore had no comment on the project as proposed. A copy of the response letter is attached. Pulte Group — Raleigh Division F&R Project No. 59Z-0459 Carthage Street Site — Protected Resources January 21, 2022 PROTECTED SPECIES REVIEW F&R visited the NC NHP Data Explorer to review the most current information regarding protected species. Based on F&R's review of the 7.5 — Minute USGS Topographic Quadrangle Map "Sanford, NC" and the supporting literature available in the NC NHP Data Explorer, there are no rare species, important natural communities, natural areas, and/or conservation/managed areas documented within the project boundary. In addition, listed or proposed listed threatened species, or listed or proposed endangered species, or designated critical habitats are not mapped at the project site. A rare species and managed area were identified within one mile of the Property; however, Managed Areas or NHP Natural Areas were not depicted within the project site on the Data Explorer map. Additionally, the U.S. Fish and Wildlife Service (USFWS) IPaC list did not identify critical habitat areas within the project area. However, three threatened, endangered, or candidate species are included on the official USFWS list of protected species that may occur in the proposed project location. Listed species include: Cape Fear Shiner (Notropis mekistocholas) — Status: Endangered (fish); Monarch butterfly (Donaus plexippus) — Status: Candidate (insect); and Harperella (Ptilimnium nodosum) — Status: Endangered (flowering plant). F&R's field observations did not identify obvious suitable habitat for the above -identified species. However, if suitable habitat is determined to be present within the disturbance area during future development of the site, a formal survey may be required in order to determine the species' presence or absence within the project area. Based upon this information, it appears that the proposed project is not likely to adversely affect federally or state listed threatened and endangered species or their designated critical habitats. Copies of the NHP response and USFWS IPaC letter are attached. CONCLUSIONS F&R reviewed information at the North Carolina State Historic Preservation Office (SHPO) and submitted a Request for Comments (RFC) letter to SHPO. The RFC letter included basic project information and documentation of F&R's information review. SHPO responded with comments indicating they are unaware of historic resources that would be affected by the project and therefore had no comment on the project as proposed. The Natural Heritage Program has provided a response that includes a table of Potential Occurrences that may occur within a one mile radius of the project site. Based on a review of this information, there do not appear to be species listed by NHP that would be adversely affected by the proposed project. Based on a review of the USFWS IPaC official species list for the project site, three federally protected species have been identified that may occur in the proposed project location. However, critical habitat was not identified within the project area and F&R's field observations did not identify obvious suitable habitat for the identified species. Based upon this information, it appears that the proposed project is not likely to adversely affect federally or state listed threatened and endangered species or their designated critical habitats.

Reid Wilson, Secretary Misty Buchanan Deputy Director, Natural Heritage Program 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: httr)s://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. Maps of NCNHP data may not be redistributed without permission. The NC Natural Heritage Program may follow this letter with additional correspondence if a Dedicated Nature Preserve, Registered Heritage Area, Land and Water Fund easement, or Federally - listed species are documented near the project area.

The species list fulfills the requirements of the U.S. Fish and Wildlife Service (Service) under section 7(c) of the Endangered Species Act (Act) of 1973, as amended (16 U.S.C. 1531 et seq.). New information based on updated surveys, changes in the abundance and distribution of species, changed habitat conditions, or other factors could change this list. Please feel free to contact us if you need more current information or assistance regarding the potential impacts to federally proposed, listed, and candidate species and federally designated and proposed critical habitat. Please note that under 50 CFR 402.12(e) of the regulations implementing section 7 of the Act, the accuracy of this species list should be verified after 90 days. This verification can be completed formally or informally as desired. The Service recommends that verification be completed by visiting the ECOS-IPaC website at regular intervals during project planning and implementation for updates to species lists and information. An updated list may be requested through the ECOS-IPaC system by completing the same process used to receive the enclosed list. Section 7 of the Act requires that all federal agencies (or their designated non-federal representative), in consultation with the Service, insure that any action federally authorized, funded, or carried out by such agencies is not likely to jeopardize the continued existence of any federally -listed endangered or threatened species. A biological assessment or evaluation may be prepared to fulfill that requirement and in determining whether additional consultation with the Service is necessary. In addition to the federally -protected species list, information on the species' life histories and habitats and information on completing a biological assessment or 12/01/2021 Event Code: 04EN2000-2022-E-00733 2 evaluation and can be found on our web page at http://www.fws.gov/raleigh. Please check the web site often for updated information or changes If your project contains suitable habitat for any of the federally -listed species known to be present within the county where your project occurs, the proposed action has the potential to adversely affect those species. As such, we recommend that surveys be conducted to determine the species' presence or absence within the project area. The use of North Carolina Natural Heritage program data should not be substituted for actual field surveys. If you determine that the proposed action may affect (i.e., likely to adversely affect or not likely to adversely affect) a federally -protected species, you should notify this office with your determination, the results of your surveys, survey methodologies, and an analysis of the effects of the action on listed species, including consideration of direct, indirect, and cumulative effects, before conducting any activities that might affect the species. If you determine that the proposed action will have no effect (i.e., no beneficial or adverse, direct or indirect effect) on federally listed species, then you are not required to contact our office for concurrence (unless an Environmental Impact Statement is prepared). However, you should maintain a complete record of the assessment, including steps leading to your determination of effect, the qualified personnel conducting the assessment, habitat conditions, site photographs, and any other related articles. Please be aware that bald and golden eagles are protected under the Bald and Golden Eagle Protection Act (16 U.S.C. 668 et seq.), and projects affecting these species may require development of an eagle conservation plan (http://www.fws.gov/windenergy/ eagle_guidance.html). Additionally, wind energy projects should follow the wind energy guidelines (http://www.fws.gov/windenergy/) for minimizing impacts to migratory birds and bats. Guidance for minimizing impacts to migratory birds for projects including communications towers (e.g., cellular, digital television, radio, and emergency broadcast) can be found at: http:// www.fws.gov/migratorybirds/CurrentBirdlssues/Hazards/towers/towers.htm; http:// www.towerkill.com; and bLtp://www.fws.gov/migratoEybirds/CurrentBirdlssues/Hazards/ towers/comtow.html. Not all Threatened and Endangered Species that occur in North Carolina are subject to section 7 consultation with the U.S Fish and Wildlife Service. Atlantic and shortnose sturgeon, sea turtles,when in the water, and certain marine mammals are under purview of the National Marine Fisheries Service. If your project occurs in marine, estuarine, or coastal river systems you should also contact the National Marine Fisheries Service, http://www.nmfs.noaa.gov/ We appreciate your concern for threatened and endangered species. The Service encourages Federal agencies to include conservation of threatened and endangered species into their project planning to further the purposes of the Act.

The purpose of the Act is to provide a means whereby threatened and endangered species and the ecosystems upon which they depend may be conserved. Under sections 7(a)(1) and 7(a)(2) of the Act and its implementing regulations (50 CFR 402 et seq.), Federal agencies are required to utilize their authorities to carry out programs for the conservation of threatened and endangered 07/26/2023 species and to determine whether projects may affect threatened and endangered species and/or designated critical habitat. A Biological Assessment is required for construction projects (or other undertakings having similar physical impacts) that are major Federal actions significantly affecting the quality of the human environment as defined in the National Environmental Policy Act (42 U.S.C. 4332(2) (c)). For projects other than major construction activities, the Service suggests that a biological evaluation similar to a Biological Assessment be prepared to determine whether the project may affect listed or proposed species and/or designated or proposed critical habitat. Recommended contents of a Biological Assessment are described at 50 CFR 402.12. If a Federal agency determines, based on the Biological Assessment or biological evaluation, that listed species and/or designated critical habitat may be affected by the proposed project, the agency is required to consult with the Service pursuant to 50 CFR 402. In addition, the Service recommends that candidate species, proposed species and proposed critical habitat be addressed within the consultation. More information on the regulations and procedures for section 7 consultation, including the role of permit or license applicants, can be found in the "Endangered Species Consultation Handbook" at: http://www.fws.gov/endangered/esa-library/pdf/TOC-GLOS.PDF Migratory Birds: In addition to responsibilities to protect threatened and endangered species under the Endangered Species Act (ESA), there are additional responsibilities under the Migratory Bird Treaty Act (MBTA) and the Bald and Golden Eagle Protection Act (BGEPA) to protect native birds from project -related impacts. Any activity, intentional or unintentional, resulting in take of migratory birds, including eagles, is prohibited unless otherwise permitted by the U.S. Fish and Wildlife Service (50 C.F.R. Sec. 10.12 and 16 U.S.C. Sec. 668(a)). For more information regarding these Acts see https://www.fws.gov/birds/policies-and-regulations.php. The MBTA has no provision for allowing take of migratory birds that may be unintentionally killed or injured by otherwise lawful activities. It is the responsibility of the project proponent to comply with these Acts by identifying potential impacts to migratory birds and eagles within applicable NEPA documents (when there is a federal nexus) or a Bird/Eagle Conservation Plan (when there is no federal nexus). Proponents should implement conservation measures to avoid or minimize the production of project -related stressors or minimize the exposure of birds and their resources to the project -related stressors. For more information on avian stressors and recommended conservation measures see https://www.fws.gov/birds/bird-enthusiasts/threats-to- birds.php. In addition to MBTA and BGEPA, Executive Order 13186: Responsibilities of Federal Agencies to Protect Migratory Birds, obligates all Federal agencies that engage in or authorize activities that might affect migratory birds, to minimize those effects and encourage conservation measures that will improve bird populations. Executive Order 13186 provides for the protection of both migratory birds and migratory bird habitat. For information regarding the implementation of Executive Order 13186, please visit https://www.fws.gov/birds/policies-and-regulations/ executive-orders/e0-13186.php. 07/26/2023 We appreciate your concern for threatened and endangered species. The Service encourages Federal agencies to include conservation of threatened and endangered species into their project planning to further the purposes of the Act. Please include the Consultation Code in the header of this letter with any request for consultation or correspondence about your project that you submit to our office.

PROBABILITY OF PRESENCE SUMMARY Breeds Apr 1 to Jul 31 Breeds May 10 to Sep 10 Breeds May 10 to Aug 31 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 and understand the FAQ "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 effort (see below) can be used to establish a level of confidence in the presence score. One can have higher confidence in the presence score if the corresponding survey effort is also high. How is the probability of presence score calculated? The calculation is done in three steps: 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. 07/26/2023 3 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. 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 Effort (1) 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. 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 off 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 specified location? The Migratory Bird Resource List is comprised of USFWS Birds of Conservation Concern (BCQ 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 filtered to return a list of those birds reported as occurring in the 10km grid cell(s) which your project intersects, and that have been identified 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 offshore activities or development. 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 specified location? 07/26/2023 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 profiles 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 specified. 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 Pacific 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 offshore areas from certain types of development or activities (e.g. offshore energy development or longline fishing). Although it is important to try to avoid and minimize impacts to all birds, efforts 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 affected by offshore projects For additional details about the relative occurrence and abundance of both individual bird species and groups of bird species within your project area off the Atlantic Coast, please visit the Northeast Ocean Data Portal. The Portal also offers 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 files 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. 07/26/2023 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 Lorin. 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 specified 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 effort (indicated by the black vertical bar) and for the existence of the "no data" indicator (a red horizontal bar). A high survey effort is the key component. If the survey effort is high, then the probability of presence score can be viewed as more dependable. In contrast, a low survey effort 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 confirm 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 confirmed. 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. 07/26/2023 IPAC USER CONTACT INFORMATION Agency: Timmons Group Name: Morgan Gilbert Address: 5410 Trinity Road, Suite 102 City: Raleigh State: NC Zip: 27606 Email morgan.gilbert@timmons.com Phone: 9848664951 Roy Cooper, Governor 9" 0 INC DEPARTMENT OF ""i ■ WMk.M 1 NATURAL AND CULTURAL RESOURCES ■-000 July 26, 2023 Morgan Gilbert Timmons Group 5410 Trinity Road Raleigh, NC 27606 RE: Westford Dear Morgan Gilbert: 13. Reid Wilson, Secretary Misty Buchanan Deputy Director, Natural Heritage Program NCNHDE-22776 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: httr)s://www.fws.gov/offices/Directory/ListOffices.cfm?statecode=37.

The site is currently zoned Cz. Stormwater measures are proposed on -site to control and treat the difference between pre - development and the post -development stormwater runoff rate for the 1-year (24hr) storm, and the 10-year (24hr) storm. These stormwater measures will provide storage volume to retain on -site runoff from the first inch of rainfall and will be released between 2 to 5 days. All proposed stormwater measures have been designed to meet the minimum of 85% average annual removal for total suspended solids. The results of the combined routing are provided below. Results for each analysis point are provided within the report. Stormwater Methodology • For each individual storm drainage inlet, a drainage area was measured as well as assigning impervious surface percentage. From this impervious percentage a rational `C' value was calculated. Impervious surfaces were given a `C' value of 0.95. This data was used for pipe sizing. The average "C" value for the site is 0.70. • RCP is specified for all storm pipe on site and off site with a Manning's N value of 0.013 • The various inlet types are shown on the plan detail sheets. Flared end sections are used at all culvert inlet and discharge points. • Spread calculations have been performed using the 4" storm event, and have been performed using a 5 minute ToC. Maximum allowable spread is 7 feet of a lane width. Structures are spaced/placed to prevent flow crossing an intersection at intersecting streets • The storm water network has been designed to pass the 10-year event and are sized to handle the 10-year storm keeping the HGL within crown of pipe • The pipes were sized using Hydraflow Storm Sewers. This program accepts the input data from each inlet, as well as physical characteristics of the storm system to be designed, and calculates flow rates and pipe sizes through the system. For rainfall data, the NOAA Atlas 14 Precipitation Intensities were utilized. Each inlet was modeled to capture 100% of the drainage area flow. The minimum storm drainage pipe size used for this project is 18 inches.

Numbers in parenthesis are PF estimates at lower and upper bounds of the 90% confidence interval. The probability that precipitation frequency estimates (for a given duration and average recurrence interval) will be greater than the upper bound (or less than the lower bound) is 5%. Estimates at upper bounds are not checked against probable maximum precipitation (PMP) estimates and may be higher than currently valid PMP values.

Numbers in parenthesis are PF estimates at lower and upper bounds of the 90% confidence interval. The probability that precipitation frequency estimates (for a given duration and average recurrence interval) will be greater than the upper bound (or less than the lower bound) is 5%. Estimates at upper bounds are not checked against probable maximum precipitation (PMP) estimates and may be higher than currently valid PMP values.

Soils are assigned to one of four groups according to the rate of water infiltration when the soils are not protected by vegetation, are thoroughly wet, and receive precipitation from long -duration storms. The soils in the United States are assigned to four groups (A, B, C, and D) and three dual classes (A/D, B/D, and C/D). The groups are defined as follows: Group A. Soils having a high infiltration rate (low runoff potential) when thoroughly wet. These consist mainly of deep, well drained to excessively drained sands or gravelly sands. These soils have a high rate of water transmission. Group B. Soils having a moderate infiltration rate when thoroughly wet. These consist chiefly of moderately deep or deep, moderately well drained or well drained soils that have moderately fine texture to moderately coarse texture. These soils have a moderate rate of water transmission. Group C. Soils having a slow infiltration rate when thoroughly wet. These consist chiefly of soils having a layer that impedes the downward movement of water or soils of moderately fine texture or fine texture. These soils have a slow rate of water transmission. Group D. Soils having a very slow infiltration rate (high runoff potential) when thoroughly wet. These consist chiefly of clays that have a high shrink -swell potential, soils that have a high water table, soils that have a claypan or clay layer at or near the surface, and soils that are shallow over nearly impervious material. These soils have a very slow rate of water transmission. If a soil is assigned to a dual hydrologic group (A/D, B/D, or C/D), the first letter is for drained areas and the second is for undrained areas.
