PROJECT DESCRIPTION Bald Head Island is part of an island group known as Smith Island, located east of the confluence of the Cape Fear River and Atlantic Ocean between Oak Island/Caswell Beach in Brunswick County and Ft. Fisher to the north in New Hanover County. The island is accessed by private boat or a private ferry service from Southport. The project's proposed borrow area is located along the northern side of Jay Bird Shoals located southwest of Bald Head Island. The proposed area encompasses approximately 72.8 acres and is located immediately north and adjacent to their previously used Jay Bird Shoals borrow area. The project's proposed disposal area consists of two locations at opposite ends of South Beach. The western location extends from Station 52+64 near the point at the west end of South Beach to Station 122+00 and the eastern location extends from Station 162+00 to Station 222+00 just east of the Shoals Club (see Sheets 2-4 of 9). Both areas are located within the Ocean Hazard Area of Environmental Concern (AEC) and specifically within the State Port Inlet Management Area. The annual erosion rate for the project area ranges from 0 — 15.2'/year per the Division of Coastal Management's 2019 Long Term Average Annual Erosion Rate update study. Within the two proposed nourishment areas, erosion rates generally increase in a west to east direction within the two disposal areas, with the highest erosion rate at the intersection of South Beach and East Beach (Station 222+00). The disposal portion of the project predominantly falls within the USACE Wilmington Harbor Sand Management Plan project area, which authorizes the placement of material excavated from the federal navigation channel on South Beach at Years 2 and 4 of a 6-year cycle, although it appears the limits of the currently proposed project extend marginally east of the historically placed limits of the federal project. South Beach last received sand under the federal project this past winter (2022-23), although disposal did not extend to the easternmost extent of South Beach. The nourishment event that occurred under this permit (#91-14) took place in the winter of 2018-19 with Jay Bird Shoals as the borrow area. Beach placement for that event did not extend east of Station 146+00. State Permit #91-14 was issued to the Village of Bald Head Island on October 21, 2014 for construction of a terminal groin structure and associated sand fillet. Phase I of the terminal groin (a 1100 ft. long section) was constructed at "The Point" in 2015. State Permits #9-95 & #67-09, both issued to the Village of Bald Head Island, also historically authorized nourishment of South Beach prior to the issuance of Permit #91-14.

Dredge volume estimate (pre -losses). The waters of the Atlantic Ocean contiguous with this portion of the Cape Fear River are classified as SB by the North Carolina Division of Water Resources. The waters are not designated as a Primary Nursery Area (PNA) by the N.C. Division of Marine Fisheries. They are CLOSED to the harvesting of shellfish. PROPOSED PROJECT: The applicant is proposing a Major Modification of State Permit No. 91-14 for the use of Jay Bird Shoals as a borrow site, with associated beach nourishment at the two opposite ends of South Beach, Bald Head Island. The application continues to state that the permitted terminal groin, sand tube groins and periodic nourishment events through the U.S. Army Corps of Engineers' Wilmington Harbor project are not sufficient alone to mitigate erosion on South Beach. A Major Modification application request was previously submitted requesting use of Frying Pan Shoals, however significant concerns were raised by resource agencies regarding the use of Frying Pan Shoals, which has led to the applicant's reevaluation of sand sources and the currently proposed expansion of Jay Bird Shoals. D E Q�� North Carolina Department of Environmental Quality I Division of Coastal Management Wilmington Office 1 127 Cardinal Drive Extension I Wilmington, North Carolina 28405 NORTH CAROLINA .,..ene or en.troomo bl a-lity /"� 910.796.7215 Village of Bald Head Island Major Modification to State Permit No. 91-14 Page Four The expanded Jay Bird Shoals proposed sand source is located immediately to the north of the previously used borrow area (see Sheets 1, and 6- 9). According to multiple Vibracores analyzed for sand quality (see Appendix D- 2022 Geotechnical Investigation Jay Bird Shoals Borrow Area Expansion), the applicant has determined that composite samples from the borrow site contain 96.2% average sand content by weight, a composite average of 2.6% fines, 0.4% granular sized material and 0.5% gravel (see the Oct 2022 "Jay Bird Shoals Borrow Site Expansion Investigation" by Olsen Associates, Inc. and Narrative). Erik Olsen with Olsen Associates, Inc. has certified the sediment is compatible with the native beach and meets the technical standards for beach fill projects described in 15A NCAC 07H .0312. The application states that excavation would be conducted to a maximum depth of -22 ft. NGVD29 with an addition +2 ft. overdepth proposed (see Sheet 8 of 9) utilizing a 24"-30" cutter suction dredge. A submerged pipeline would provide disposal on the South Beach shoreline. According to the applicant, existing water depths of the overall borrow area range from approximately -5 to -16 NGVD29 (See Sheets 8-9). Hydrographic surveys and a submerged cultural resource remote -sensing survey resulted in the identification and proposal of a single buffer area immediately outside the proposed sand source to be avoided (see Sheets 7 and 9 of 9 and Appendix C- T.A.R. Archeological Report). The narrative states physical monitoring of the proposed excavation area would be conducted by the Village of Bald Head Island immediately after construction, and annually for three years, then biannually after the third year. Monitoring would include the entire borrow site and a 500' buffer outside the borrow area. The applicant states that monitoring data would be utilized to calculate deposition rates or "recharge" of the site as part of the existing BHI comprehensive Shoreline Monitoring Program, which is reported annually. (Copies of past reports are available upon request.) The proposed limits of the beach fill template would extend from Station 52+64 to Station 122+00 on the west side of South Beach and from Station 162+00 to 222+00 at the eastern side of South Beach. The applicant states that the beach construction berm would conform to the previously authorized maximum berm elevation of +9' NGVD29. The beach profile would result in a total approximate average fill width of 450' along the length of the two placement areas along the western and eastern ends of South Beach, and a total combined shoreline length of 12,936'. The placement template would be constructed at a 15H:1V slope (see Sheets 3-5 of 9) with an average berm width of approximately 150'. According to the applicant, an estimated 119 acres of fill (-800,000 cubic yards) would be placed below mean high water. The proposed beach fill project would excavate up to 1 million cubic yards of material. It is estimated that the identified Jay Bird Shoals Site has a maximum compatible volume of 1.4 million cubic yards of material available within the proposed dredge template. The application states work would be conducted from Nov 16 to April 1. Physical monitoring of the borrow area would take place for 3 years post -construction and biennially after the 3 year time period to calculate infilling rates.

ANTICIPATED IMPACTS: The proposed excavation of the Jay Bird Shoals Borrow site could result in the excavation of up to 72.8 acres of Public Trust Area and Estuarine Waters. The subsequent beach disposal would result in the filling of approximately 29 acres of unvegetated beach above MHW and approximately 119 acres of area below MHW. Increases in turbidity should be expected during construction. The applicant has stated that standard conservation measures would be applied, as outlined in Section 3.1.4 of the narrative (Avoidance and Minimization Measures). The application states that no vegetative plantings are proposed with the project and the Village of Bald Head Island will be responsible for any site revegetation or stabilization that is deemed necessary by resource agencies in a separate contract. The application also states visual surveys of escarpments and remediation would be conducted prior to turtle nesting season and that work would occur during the winter months to reduce biological impacts; however, a November 16- April 1 window has been proposed in the application.

DCM MP-1 Section 6.0 Additional Information 3.1 Section 6. a. Project Narrative 3.1.1 Introduction The south -facing shoreline of Bald Head Island (i.e. South Beach) experiences on -going and chronic erosion resulting in predictable sand losses and shoreline recession. Severe erosion has been chronicled along South Beach (particularly its western reach) since the 1970s. Prior to 2015, the highest rates of sand loss occurred principally at the extreme west end of South Beach in the vicinity of the Cape Fear River entrance. This prompted the Village of Bald Head Island (Village) to procure authorizations for, and subsequently construct, a 1,300-If terminal groin at this location. Construction of the terminal groin structure was completed in December 2015. While the terminal groin addresses chronic shoreline losses along western South Beach, it has been documented that the terminal groin and existing sand tube groin field are not sufficient, in and of themselves, to prevent or to adequately offset sand losses from South Beach or West Beach. As a result, periodic nourishment through both the federally sponsored Wilmington Harbor dredge and disposal project and Village -sponsored projects are required to mitigate erosion along the entirety of South Beach and West Beach. The threat to existing homes, dunes, and infrastructure because of the erosion and shoreline recession has prompted the Village to seek longer term beach nourishment options. Predicted sand volume needs for South Beach and West Beach were identified in the terminal groin EIS (for both the terminal groin alternative and non-structural alternatives). Based upon this analysis, the Village identified and submitted permit authorization requests for use of a borrow site on Frying Pan Shoals (a sand source site with the potential to satisfy larger sand volume requirements for South Beach and West Beach). However, recent agency comments in response to this request have prompted the Village to evaluate and pursue other practicable alternatives including an expansion of the Jay Bird Shoals (JBS) permitted borrow area. Specifically, agencies recommended the prioritization of the use of JBS over the use of Frying Pan Shoals (FPS). Further information regarding existing site conditions and the proposed work activities of the current JBS expansion project are provided below. 3.1.2 Investigations In order to determine the proposed borrow site expansion project's effects on potentially significant submerged cultural resources, CAI contracted with Tidewater Atlantic Research, Inc. (TAR) of Washington, North Carolina to conduct a magnetometer and acoustic survey. The remote sensing investigation conducted by TAR archaeologists was designed to provide accurate and reliable identification, assessment and documentation of submerged cultural resources in the study area. A copy of the TAR report in its entirety is included as Appendix C. Having quantified potential sediment availability over depth, Olsen Associates, Inc., (OAI), authorized the acquisition of ten (10) VIBRACORES within and adjacent to the proposed expansion area. The locations of the intended cores are depicted in Sheet 7 of 9, Appendix A. Two (2) cores were sited in previously dredged areas within Area 3 of the original site for purposes of assessing the quality of the depositional material. The firm of Athena Technologies, Inc. (Athena) was contracted to acquire the desired VIBRACORES and to log, document, and perform the requisite laboratory analyses (i.e. size characteristics, % shell, % fines, etc.). Athena completed the field work associated with VIBRACORE acquisition in early July, 2022. Each core was sampled at two discrete locations as well as a composite sample that extended over the maximum design depth of excavation (-22 ft. NGVD29 +2 ft. overdepth). Such composite samples were based upon the apparent absolute depth of visible, desirable material and verification of same based upon the results of the prior 2009/2010 and 2018/2019 projects at this general location. In addition to well defined grain size distribution analyses, the percentage carbonate material as well as fines were computed for each composite sample over depth.

As such, investigations into the expansion of the borrow area were conducted by Olsen Associates, Inc. Based upon updated bathymetric conditions, the available neat volume of borrow site sand within the expanded site above a design elevation of -22 ft. NGVD is approximately 1.4 Mcy. This is theoretically sufficient for the construction of a potential interim beach fill in/or about 2025. The maximum depth of excavation during dredging would be limited to -24 ft. NGVD, as in the prior two (2) dredging events. This ensures that beach quality sediments are excavated, as well as that the exposed borrow site post -construction substrate is suitable for expeditious benthic recovery. The intended project in -place fill volume required is estimated at 1 Mcy +/-. Material placement will occur along 6,936 If of the western end of South Beach and the terminal groin fillet (Station 52+64 to 122+00) and 6,000 If along the eastern end of South Beach (Station 162+00 to 222+00). The South Beach construction berm will maintain an approximate average elevation of +9 ft. NGVD and average up to 500 ft in width. A mild slope in the seaward direction will be introduced into the berm (by grading) to reduce post -placement scarping and enhance post - construction turtle nesting activities. Should dune erosion or benching be evident at the time of construction, up to 5 cy of sand per ft. of shorefront would be mechanically moved and graded to repair the dune line. Any revegetation necessary for dune stabilization would be performed by the Village under separate contract after fill placement completion by the dredge contractor. The proposed timing of the work would be between November 16 and April 1 of the following year. Work would be performed by a cutter suction dredge with direct deposit on S. Beach by pipeline. It is anticipated that a submerged pipeline can cross the federal navigation project without the need for burial, i.e. seabed placement below the authorized channel depth of -44ft. MLW. It is understood that recipient beach clast counts in accordance with the requirements of .0312(1)(h) will be required prior to material placement. See Appendix A for a site location map and work plats. 3.1.4 Avoidance and Minimization Measures The identification and use of the expanded Jay Bird Shoals borrow site was prompted by agency comments received during the review of the Village's request to develop a sand source site on Frying Pan Shoals. Resource agencies recommended the prioritization of the use of JBS over FPS until such time the BOEM-funded research of FPS is completed. The current JBS expansion project is being proposed as a result of these requests. Based upon prior consultation with the Corps of Engineers and the U.S. Fish and Wildlife Service (FWS) for previous beach nourishment projects on Bald Head Island and the North Carolina Coastal Beach Sand Placement Statewide Programmatic Biological Opinion (August 2017), standard conservation measures will be employed. These include, but may not be limited to, the following: 1. Nourishment to occur during winter months (reduced biological activity); 2. Utilization of beach quality sand (compatible with recipient site); 3. Visual surveys of escarpments and remediation prior to sea turtle nesting season; 4. Qualitative assessment of sand compaction subsequent to completion of beach placement (typically with staff of NC Wildlife Resource Commission); Major Modification to CAMA Permit # 91-14 — August 2023 Village of Bald Head Island Renourishment Project Village of Bald Head Island, Brunswick County, North Carolina 9 5. The project will allow for undredged areas in proximity to be left undisturbed to promote more rapid recolonization of benthos (as was documented for previous Jay Bird Shoals and Bald Head Creek Shoals projects); 6. The project will avoid hard -bottom habitat; 7. The project will avoid Primary Nursery Area (PNA) impacts; 8. Avoidance of shorebird and colonial waterbird nesting areas; 9. The project will utilize hydraulic cutter suction dredge (thereby avoiding and minimizing physical entrainment of species in proximity to the dredge operation); and 10. The project will include post -project physical monitoring of borrow site (i.e. assessment of physical recovery); (see Section 3.15 below). 3.1.5 Post -Construction Monitoring The Village, as the Permittee, will perform physical monitoring of the dredged borrow site immediately after construction, annually for three (3) years, and biennially thereafter. The post -construction bathymetry will be compared with subsequent monitoring results to calculate in -filling of the site. The results of the monitoring will be incorporated into the Village's existing comprehensive Shoreline Monitoring Program and reported annually. The footprint of each monitoring survey shall include the entire permitted site as well as the actual area of excavation within. Any changes in morphology to the Jay Bird Shoals formation will be evaluated and included within the results of the monitoring report. Any changes in bathymetry proximate to cultural resource buffers will be monitored and reported.

(OAI) of Jacksonville, Florida is the project engineer representing the Village of Bald Head Island (VBHI), North Carolina in developing and permitting an expanded borrow site on Jay Bird Shoals (JBS) near the entrance to the Cape Fear River. Material from the JBS borrow site will be used by the VBHI for engineered beach renourishment. In order to determine the proposed project's effects on potentially significant submerged cultural resources, OAI contracted with Tidewater Atlantic Research, Inc. of Washington, North Carolina to conduct a remote -sensing survey of the proposed borrow site. Field research for the project was conducted on 31 August and 1 September 2022. The survey was carried out with both magnetic and acoustic remote -sensing equipment. Navigation and data collection was controlled by differential global positioning. Analysis of the JBS survey data identified a total of 26 magnetic anomalies. Analysis of the magnetic data indicates that a cluster of four anomalies have collective signature characteristics that could represent historic vessel remains. Because JBS has a high potential for historically significant shipwrecks, those four anomalies are recommended for avoidance or additional investigation. The remaining 22 magnetic anomalies appear to be generated by modern debris such as fish and crab traps, pipes, small diameter rods, cable, wire rope, chain, small boat anchors and possibly ordnance associated with fortifications on Bald Head Island and/or Oak Island. No additional investigation of those buffered four magnetic anomalies is recommended in conjunction with the proposed dredging unless the avoidance buffer could be impacted or anomaly identification is desirable. Nine of the remaining anomalies are located in the 200-foot perimeter buffer. One magnetic anomaly is located outside the survey area. The 12 magnetic anomalies inside the borrow area are not considered to be potentially significant. None of the magnetic anomalies have an associated acoustic signature. The one sonar target is a linear object that could represent a piling or dayboard pole. m Table of Contents Abstract Listof Figures..................................................................................................................................

(OAI) of Jacksonville, Florida is the project engineer representing the Village of Bald Head Island (VBHI), North Carolina in its efforts to expand an offshore borrow site near the island for engineered beach renourishment. The expanded sand source for material is a borrow area located approximately a mile west of Bald Head Point and adjacent to a previously utilized borrow site. In order to determine the proposed project's effects on potentially significant submerged cultural resources, OAI contracted with Tidewater Atlantic Research, Inc. (TAR) of Washington, North Carolina to conduct a magnetic and acoustic survey of the proposed borrow site extension. The remote -sensing investigation conducted by TAR archaeologists was designed to provide accurate and reliable identification, assessment and documentation of submerged cultural resources in the study area. The assessment methodology was developed to comply with the criteria of the National Historic Preservation Act of 1966 (Public Law 89-665), the National Environmental Policy Act of 1969 (Public Law 11-190), Executive Order 11593, the Advisory Council on Historic Preservation Procedures for the protection of historic and cultural properties (36 CFR Part 800) and the updated guidelines described in 36 CFR 64 and 36 CFR 66. Results of the remote -sensing investigation were designed to furnish OA and VBHI with the remote -sensing data required to comply with the North Carolina State Historic Preservation Office (NCHPO) and North Carolina Department of Natural and Cultural Resources (NCDNCR) submerged cultural resource legislation and regulations. Field research for the project was conducted on 31 August 2022 and 1 September 2022. The survey was carried out with both magnetic and acoustic remote -sensing equipment. Navigation and data collection was controlled by differential global positioning. Analysis of the JBS survey data identified a total of 26 magnetic anomalies. Analysis of the data indicates that a cluster of four anomalies have collective signature characteristics that could represent historic vessel remains. Because JBS has a high potential for historically significant shipwrecks, those four anomalies are buffered and recommended for avoidance or additional investigation if the avoidance buffer could be impacted or anomaly identification is desirable. Nine of the remaining 22 anomalies are located in the 200-foot perimeter buffer. One magnetic anomaly is located outside the survey area. The 12 unbuffered anomalies inside the borrow area are not considered to be potentially significant. Those anomalies appear to be generated by modern debris such as fish and crab traps, pipes, small diameter rods, cable, wire rope, chain, small boat anchors, and possibly ordnance associated with fortifications on Bald Head Island (BHI) and Oak Island. None of the magnetic anomalies have an associated acoustic signature. Analysis of the sidescan sonar data identified only one acoustic target. The signature for that target represents a linear object on the bottom surface. No magnetic anomaly is associated with the target. It likely represents a piling or navigation reference dayboard. Analysis of the sub - bottom profiler data identified no geological features or targets associated with the magnetic anomalies. 2 Project Personnel Project survey personnel consisted of Principal Investigator Gordon P. Watts, Jr., Vessel Captain Ralph Wilbanks, and Remote -Sensing Operator Harry Pecorelli. Senior Historian Robin Arnold carried out the archival, cartographical, and literature research. Dr. Watts analyzed the remote -sensing data. Dr. Watts and Ms. Arnold prepared this document. Project Location The remote -sensing project area is situated on JBS, which is located at the entrance to the Cape Fear River on the west side of the navigation channel (Figurel). The potential borrow site is located near the southwest of the shoals approximately a mile west of Bald Head Point. 0 0 0 0 v 0 0 m 2290000 22951}60 2300000 I (pi 31kiF 4D Ia` fs{F)r. -- il�:ti,:,T u'J?•R7 {1a� fa 101t Nphn -- k, -0a 2',lll a�f '1I `tip•',.; c5 :: _ Orl ? ar GyaL n10 ciw7;�, 1- I ----&l�1�'; - - _i'2 — ---�'f l{1i '`,I > it 14 G ~' 17 I •:I � llso _s 23f1 I lit i� ,� r `�') 1e,.. �9 1� I' $tlnF,e La�atlan•�f FlR2.SS 2c � I' i l � � f av ' 1' ti 'r F' ,Sa r'f t.

To ensure sufficient data would be available to locate any potentially significant targets in the project area, remote -sensing data were collected along 36 parallel lanes spaced on 50-foot intervals. The area surveyed included a 200-foot perimeter buffer zone so that magnetic anomalies and/or acoustic targets located along the periphery of the borrow area could be identified and the impact from dredging assessed.

Research Methodology Literature and Historical Research The TAR historian conducted a literature search of primary/scholarly secondary sources to find significant cultural resources within the proposed project area. A background history of BHI and the lower Cape Fear region was updated. Preliminary wreck -specific information was reviewed in manuscripts and published sources that include; Wreck Logs: 5 November 1883- 18 January 1906. Life Saving Station No. Cape Fear, District No. Six (Old Baldy Foundation n.d.), Merchant Vessels of the United States (U.S. Bureau of Navigation 1906 through U.S. Coast Guard 1970); A Guide to Sunken Ships in American Waters (Lonsdale and Kaplan 1964); Encyclopedia ofAmerican Shipwrecks (Berman 1972), Shipwrecks of the Civil War (Shomette 1973), Merchant Steam Vessels of the United States 1790 -1868 (Lytle and Holdcamper 1975), Shipwrecks of the Americas (Marx 1983), Official Records of the Union and Confederate Navies in the War of the Rebellion (National Historical Society 1987), and The Story of Cape Fear and Bald Head Island (Duffus 2017). Newspapers and journals digitally archived by Britishnewspaperarchive.co.uk, Chronicling America (Library of Congress), Genealogybank.com, Fold 3, Navyrecords.org.uk, Newspapers.com, and Newspaperarchive.com were examined for site -specific terms. In addition, the National Register of Historic Places database (maintained by the National Park Service) and the Office of Coast Survey's Automated Wreck and Obstruction Information System (AWOIS) was queried. According to the second website, "AWOIS records are not comprehensive. There are wrecks in AWOIS that do not appear on the nautical chart and wrecks on the nautical chart that do not appear in AWOIS. In 2016 the Office of Coast Survey stopped updating the AWOIS database. Reported wrecks that have been salvaged or disproved by further investigation are not included in AWOIS". Relevant shipwrecks based on primary and secondary sources are listed in Appendix A. El Personnel at the North Carolina Underwater Archaeology Branch (UAB), the North Carolina Maritime Museum (Southport), and the Brunswick County Library (Southport) were contacted [January 2022 and August 2022] for shipwreck data associated with Bald Head Island (BHI) and the lower Cape Fear River. TAR personnel interviewed archaeologists, area residents, and professional historians knowledgeable in maritime and shipwreck research to solicit their assistance to generate relevant data. Remote -Sensing Survey In order to reliably identify submerged cultural resources, TAR archaeologists conducted a systematic remote -sensing survey of the proposed dredge site. All survey activities were conducted from a 24-foot Parker vessel (Figure 2). In order to fulfill the requirements for survey activities in North Carolina, magnetic and acoustic remote -sensing equipment were employed. This combination of remote sensing represents the state of the art in submerged cultural resource location technology and it offers the most reliable and cost-effective method to locate and identify potentially significant magnetic anomalies and/or acoustic targets. Data collection was controlled using a differential global positioning system (DGPS). DGPS produces the highly accurate coordinates necessary to support a sophisticated navigation program and assures reliable target location. Figure 2. Project survey vessel. An EG&G GEOMETRICs G-881 marine cesium magnetometer, capable of plus or minus 0.001 gamma resolution, was employed to collect magnetic data in the survey area (Figure 3). To produce the most comprehensive magnetic record, data was collected at 10 samples per second. Due to shoal water within the project area, the magnetometer sensor was towed at the water surface at a speed of approximately three to four knots. Magnetic data were recorded as a data file associated with the computer navigation system. Data from the survey were contour plotted using QUICKSURF software to facilitate anomaly location and definition of target signature characteristics. All magnetic data were correlated with the acoustic remote sensing records. 5 Figure 3. Launching the Geometries 881 Cesium Vapor magnetometer. A KLEIN 3900 450/900 kHz digital sidescan sonar (interfaced with CHESAPEAKE TECHNOLOGY SONARWIZ.MAP data acquisition software was employed to collect acoustic data in the survey area (Figure 4). Due to shoal water within the project area, the sidescan sonar transducer was deployed and maintained between 3 and 5 feet below the water surface. Acoustic data were collected using a range scale of 30 meters to provide a combination of 200% coverage and high -target signature definition. Acoustic data were recorded as a digital file with SonarWiz.MAP and tied to the magnetic and positioning data by the computer navigation system. Figure 4. Launching the Klein 3900 sidescan sonar. C A TABLE AgGPS was used to control navigation and data collection in the survey area. That system can be used to generate highly accurate coordinates for the computer navigation system. The DGPS was employed in conjunction with an onboard Compaq 2.4 GHz laptop loaded with a HYPACK navigation and data collection software program (Figure 5). Figure 5. Bridge electronics for navigation and data collection. All magnetic and acoustic records were tied to positioning events generated by HYPACK. Positioning data generated by the navigation system were tied to magnetometer records by regular annotations to facilitate target location and anomaly analysis. All data is related to the NCSP Coordinate System, NAD 83. Historical Background European settlement of the present day Cape Fear region began as early as 1526 when Lucas Vasquez de Ayll6n led an expedition from Florida into the Cape Fear region. One of the Spanish vessels was recorded lost near the mouth of the Cape Fear River, referred to by the Spanish as the Jordon River. During the brief existence of the Spanish settlement, the area was known as the "Land of Ayll6n" (Lee 1965:3-4). A chart drawn during the very late sixteenth century or early seventeenth century shows the location of the Cape Fear by the proximity to the Island of Bermuda (Figure 6). The next attempt to settle the Cape Fear region came almost a century and a half later with the arrival of the English (Figure 7). Settlers from New England came to the area eager to establish a Puritan colony in the less harsh climate of the southern Colonies. Under the leadership of Captain William Hilton, a group arrived in the summer of 1662 to find a suitable location. Arriving at the river and "Cape Fear" as he called it, the group remained for three weeks during which time they purchased the surrounding area from the indigenous population. The Puritan settlers that followed during the winter of 1662 remained in the Cape Fear vicinity for only a brief time before abandoning the area (Lee 1965:4-5). 7 its We AVAjox _ ��= ❑ i��{c► raft, iea �` �� ram- ���,►� Figure 6.

J X In early 1663, King Charles II granted territory south of Virginia to eight noblemen in tribute for restoring the Stuart dynasty to the monarchy. That conveyance included the area from Georgia to the Albemarle Sound region of North Carolina. The territory was divided into three counties: Albermarle [Albemarle Sound area], Clarendon [Cape Fear region] and Craven [South Carolina]. Shortly after, the Lords Proprietors received a proposal from a group of Barbadians for a settlement within the Cape Fear region. In late spring 1664, a group of 200 settlers, under the command of John Vassall, established a colony at the confluence of the Charles [modern Cape Fear] River and Town Creek (Potter 1993:5-6). The capital, Charlestown, was the first English town in Carolina (Lee 1965:5). The colony was reported to have reached a population of 800 and extended some 60 miles along the river at its zenith. In October 1665, a second expedition by the Barbadians was launched with the intent of establishing a colony in the vicinity of Port Royal. A small fleet consisting of a frigate, sloop and a flyboat, under command of Sir John Yeamans, stopped at the Charlestown settlement after an arduous journey from Barbados. While entering the river, the flyboat, carrying the new colony's armament, ran aground on the shoals on the west side of the channel [modern JBS] and was lost (Potter 1993:9, 29). The loss of this important cargo abruptly ended the Port Royal venture. Within another two years Charlestown would also be abandoned. Difficulty in obtaining supplies, differences between the proprietors and settlers over land policies and hostilities with the Natives resulted in the colony being deserted by late 1667 (Potter 1993:10- 11). In 1726, permanent settlements on the lower Cape Fear were established by South Carolina and upper North Carolina colonists (Lee 1977:7). On the west bank of the river, about 12 miles above its mouth and several miles below a shoal in the river called "the Flats," Maurice Moore established the town of Brunswick. A shoal located at the mouth of Town Creek impeded larger ships from venturing further upstream. Situated below "the Flats" Brunswick was accessible to vessels of large or small size (Lee 1977:12). In April 1733, another community was established 15 miles upstream from Brunswick. The new settlement became known as New Town or Newton to distinguish it from the "old town" of Brunswick. In 1740, the town was incorporated and the name was changed to Wilmington (Lee 1977:12). As hostilities with France and Spain grew during the 1740s Governor Gabriel Johnston authorized the construction of a fort along the lower Cape Fear to protect the burgeoning towns of Brunswick and Wilmington. Construction began in July 1745 on a small bluff overlooking the mouth of the river. Johnston's Fort, as it was called, was still uncompleted in 1748 when two Spanish vessels entered the river and raided Brunswick (Carson 1992:20). Efforts to finish construction intensified after the raid and in less than a year the fort was completed. The resulting structure was small and poorly constructed. It was manned by only three men and armed with four rusty cannons (Carson 1992:20; Figure 8). In 1751, the fort was assigned to double as a quarantine station. Development based upon a maritime economy played a major role in the growth of both Wilmington and Brunswick during the eighteenth century. Vessels of varying size entered the Cape Fear from other coastal ports, the West Indies and Europe. Larger vessels, unable to cross over "the Flats," called at Brunswick, while vessels of smaller size could travel further 10 up the river to Wilmington. Consequently, Brunswick was established as the center for overseas shipping and Wilmington as the center for local and West Indian trade (Lee 1977:16- 17). Rice, cattle, swine, lumber and naval stores made up the majority of the exports from the port district of Brunswick. Prior to the Revolution numerous ships left the Cape Fear River for other ports. The West Indies served as the main destination of these ships with English ports following a close second. A lesser number carried cargo to coastal ports, mostly in the northern colonies, but occasionally some ventured south, down the coast to Charleston (Lee 1977:33). The Cape Fear region played a minor role in the events of the American Revolution. In June 1775, Royal Governor Martin fled from New Bern to Fort Johnston, then under the protection of the British man-of-war Cruizer. Growing patriot activity in the area forced the governor to relocate to the warship a month later. All portable materials were transferred to the ship and the fort's guns were spiked and pushed into the river (Carson 1992:22; Figure 9). Local forces later burned the fort and its outbuildings. Knowing that a large number of Loyalists inhabited the interior of the colony Governor Martin initiated a plan to subjugate the region using a combination of British and Loyalist forces (Sprunt 2005:113). British reinforcements arrived off the North Carolina coast by the end of March, but by then the opportunity to subdue the colony had passed. On 27 February 1776, Colonel James Moore and the First North Carolina Continentals with a group of militias defeated a contingent of Scottish Loyalists at the battle of Moore's Creek Bridge. This battle, called the "Lexington and Concord of the south," kept the British from occupying the South at the beginning of the war (Powell 1989:180-182). Naval operations were of limited importance in the Cape Fear region. In mid-1776, British warships began taking up regular station over the mouth of the river. In May of the following year two British men-of-war entered the river and destroyed a number of colonial vessels at anchor (Watson 1992:29; Figure 10). To counter the threat posed by British warships the General Assembly voted to purchase and arm three brigs for the defense of the Cape Fear River. However, these vessels proved inadequate for the task and suggestions were made for either selling them or sending them on trading or privateering expeditions (Watson 1992:29). The lower Cape Fear remained quiet until 1781 when Major James H. Craig was dispatched by Lord Cornwallis in Charleston to take Wilmington. Craig, with a force of 18 vessels and 400 troops, quickly captured the defenseless town (Sprunt 2005:114). From Wilmington, Craig dispatched parties throughout the countryside to rally local Loyalists and to obtain supplies for Cornwallis's troops, then marching through North Carolina. After being checked by Colonial forces in the battle of Guilford Courthouse the British retreated to Wilmington to recoup and replenish supplies. Later, when Lord Cornwallis moved north to suppress Virginia, Craig remained behind in Wilmington to disrupt Colonial activity in that region. News of Cornwallis's surrender at Yorktown made the British position in Wilmington untenable and on 17 November Major Craig evacuated the city. 11 E13�1 I'LA-N OF T 7.I E Figure 8.

Detail of 1780 Plan de la riviere du Cap Fear depuis la Barre jusques a Brunswick (courtesy of the LOC). 14 After the conclusion of the war there was a shift in the maritime development of the Cape Fear region. Almost all the ships that left the Cape Fear now went to Charleston and few to England or the West Indies (Lee 1977:33). Inbound ships now proceeded up to Wilmington. This shift brought about the decline of the town of Brunswick as was indicated by the change in name of the "Port of Brunswick" to the "Port of Wilmington" (Lee 1977:34). During the last decades of the eighteenth century the area that would become the town of Southport consisted of little more than the remains of Fort Johnston and the homes of local river pilots. The region's potential, however, was realized by three men from Wilmington, Joshua Potts, John Brown and John Husk, who the viewed the area, with its salubrious sea breezes, as an ideal spot for a new town. Though the men's initial petition was rejected in 1790 the group persevered and on 15 November 1792, the General Assembly issued a charter for the establishment of a town on the bluff overlooking the mouth of the river. The town was named Smithville, after Benjamin Smith who introduced the bill into the legislature. The town was laid out with lots offered for sale in Wilmington and Fayetteville newspapers. The charter specified that no person could purchase more than six lots in their name and the purchase price of lots was to be 40 shillings per lot (Carson 1992:26). The town plan also reserved space for Fort Johnston which was rebuilt in 1804. With the growing amount of vessel traffic sailing up to Wilmington there arose a need for improvements in the navigability of the river. As early as 1784, measures were taken to improve the conditions of the lower Cape Fear River (Lee 1977:36). Improvements were needed at the treacherous entrances to the river, at the Bar and upstream at New Inlet. Three major shoals between Wilmington and the sea also caused problems for ships trying to navigate the river. The "upper shoal," located near the foot of Clarks Island, off the southern tip of Eagles Island, had eight and one-half feet of water. The "middle shoal," also known as "the Flats," had nine feet. The "lower shoal," at the foot of Campbell Island, had nine and one-half feet. The main channel of the river was then located in a narrow passage between Campbell Island, Clarks Island and the west bank (Lee 1978:112). In addition to the shoals, ships deliberately sunk during the American Revolution as obstructions needed to be removed (Lee 1977:36-37). Around 1819, Hamilton Fulton, a noted English engineer, was hired to make improvements on the Cape Fear River mainly between Wilmington and the ocean where a system of jetties was planned. Work continued for six years until financial limitations halted this project. Some improvements were made on the river up until the start of the Civil War with sporadic financing by the state and local Wilmington businessmen (Lee 1977:37). Steam vessels first appeared on the Cape Fear River in 1817. The first steamboat to arrive was the side -wheel Prometheus, built in Beaufort for a firm in Wilmington that intended to run the vessel from Wilmington to Fayetteville and Southport. The following year the Clarendon Steamboat Company was established at Wilmington. The company held the exclusive right to operate steamboats on the Cape Fear for a period of seven years provided that it kept one boat in service. In addition to the Prometheus, the side -wheel Henrietta, also made regular runs between Wilmington and Fayetteville (Lee 1977:37-38). By 1822, a second steamship venture, 15 the Cape Fear Steamboat Company, had begun service on the river. With time the number of steamboats on the river increased significantly (Lee 1977:38: Figure 11). By the 1850s, nearly a hundred vessels of all types were in Wilmington at the same time. Many of the ships were large square-rigged foreign craft, while others were side -wheel steamers. Most, however, were American schooners engaged in the coastal trade (Lee 1978:116). Development of the Cape Fear region was soon disrupted by the Civil War. After Confederate forces in South Carolina attacked the U.S. garrison at Fort Sumter, President Abraham Lincoln declared a state of open rebellion and called for volunteers to preserve the Union. Lincoln also issued a proclamation on 19 April 1861 establishing a blockade of Confederate ports in South Carolina, Georgia, Florida, Alabama, Mississippi, Louisiana and Texas. Eight days later, Lincoln extended the blockade to include ports in Virginia and North Carolina. With North Carolina's withdrawal from the Union, Governor John W. Ellis ordered the occupations of forts Johnston and Caswell. Union naval forces were inadequate to properly enforce the blockade at the onset of the war. In 1861, U.S. navy registers listed 90 vessels, 50 of which were propelled by sail and were considered obsolete for the task at hand. The remaining 40 were steam, but several of the deep draft vessels proved unsuitable for the shallow southern waters. Eight others were laid up while 22 vessels remained at station off foreign shores and would require at least six months travel to reach the United States (Browning 1980:24). However, within a few months of Lincoln's proclamation, the new Secretary of the Navy, Gideon Welles, took steps to implement an effective blockade off the southern coastline. The navy department bought or leased nearly any vessel that could be of service. In nine months, U.S. navy agents purchased 136 ships, constructed 52 and commissioned and repaired another 76 (Engle and Lott 1975:180). The Union blockade in turn gave rise to the practice of blockade running. At the beginning of the blockade, practically any vessel was considered suitable for breaking through the Atlantic squadrons to carry cargo in or out of the isolated southern ports. The most successful of the early runners were steamers that had belonged to the Southern Coasting Lines and were idle due to the outbreak of the war. The illicit trade carried on by these ships reaped considerable profit, but failed to compare with the great capital resources brought in during the latter part of the war. Wilmington provided North Carolina with a deepwater port. By 1860, Wilmington had emerged as a modern shipping center with excellent internal communication. Three railroads ran through the city and daily steamboat service to Charleston and New York, as well as, up the Cape Fear River to Fayetteville. With the capture of New Bern, Roanoke Island and Beaufort, Wilmington was the only North Carolina port left open for the importation and exportation of goods. As long as supplies were imported through the two inlets of the Cape Fear River and transported along the railroad lines, which connected with Lee's army in Virginia, the Confederacy had a lifeline. Wilmington soon became the most vital seaport in the "Southern Cause" (Pleasants 1979:15; Figure 12; Figure 13). 16 S M I T II'S I S L A N D Figure 11.

Located 28 miles from the mouth of the Cape Fear River, the port had access to the Atlantic through two separate entrances; eastward through New Inlet and southward through the river mouth (Figure 14). Although the two entrances were only six miles apart, Smith's Island, a strip of sand and shoal, lay in between. Continuing along Cape Fear were the dangerous Frying Pan Shoals, which extended 10 miles further into the Atlantic, making the distance by water between the two entrances a little less than 40 miles (Soley 1883:91). This geographical configuration proved highly advantageous for blockade runners and the initial blockade of Wilmington proved ineffective. When the Daylight, the first and at the time the only Union vessel sent to blockade these waters, arrived, it immediately experienced the difficulties associated with guarding the dual entrances of the Cape Fear River. While pursuing a steamer out of the western bar entrance, the Daylight inadvertently allowed several other small vessels to pass out of the New Inlet entrance. Within three months of the Daylight's arrival, 42 vessels either entered or cleared Wilmington (Browning 1980:27). Figure 14. July 1864 image of the deck of the blockade runner Lilian running into Wilmington (courtesy of the NYPL). During a two-year period (January 1863-November 1864), Confederate naval sources listed numerous vessel stations on the Cape Fear. These vessels were identified as: the ironclad sloop North Carolina, the floating battery Artic, the steam gunboat Yadkin, the steam gunboat Equator, the torpedo boat Squib, and the ironclad sloop Raleigh, and two, long one -gun cutters. In November 1864, Confederate Secretary of the Navy Stephen Mallory also reported to President Jefferson Davis that two new torpedo boats were under construction at Wilmington (U.S. Navy [USN], 1921, ser. II, 2:passim). 20 The capture of Wilmington proved difficult because both entrances to the Cape Fear were guarded by powerful fortifications and lesser works. Collectively those fortifications became known as the Lower Cape Fear Defense System. The central point of that system was Fort Fisher, located on Confederate Point. That fortification was originally a small earthwork constructed to protect New Inlet. By 1864, Fort Fisher had become the largest seacoast fortification in the Confederacy. Shaped like an inverted "L," Fort Fisher's land face ran 628 yards and was guarded by 20 of the heaviest seacoast guns. The sea face included a 130-pound Armstrong rifle and a 170- pound Blakely, both from England (Browning 1980:35). Extending from the land face was a string of torpedoes, which could be exploded from inside of the fort (Pleasants 1979:22). Mound Battery, towering to a height of 60 feet with two mounted heavy guns, stood near the end of Confederate Point. Augusta Battery, which stood behind Mound Battery, was located near the river (Pleasants 1979:24). Fort Holmes, on the other side of New Inlet on Smith's Island, shared the protection of Smith's Inlet in the Cape Fear River with the batteries at Oak Island. Oak Island, located opposite Fort Holmes, held another series of forts and batteries, such as Fort Campbell, Fort Caswell and Battery Shaw (Pleasants 1979:24). Fort Caswell guarded the western bar entrance. Captured by Confederate militia on 14 April 1861, Caswell was renovated into a strong casemated work with new armament consisting of seven 10-inch, four 8-inch Columbiads and one 9-inch Dahlgren gun (Browning 1980:35; Pleasants 1979:24). Both Fort Caswell and Fort Holmes were responsible for shelling union vessels in the Middle Ground area, including the stranded tug Violet which went aground off the Western Bar Channel on the night of 7 August 1864. After his tug struck the shoal Ensign Thomas Stothard requested assistance from the crew of the nearby 866-ton brig USS Vicksburg to attempt to re- float the Violet. Despite their quick response, the extra manpower and effort proved fruitless as Stothard was ordered to fire the Violet after midnight. In response to a court of enquiry [sic] investigation, Captain Stothard submitted an incident report to Captain B.F. Sands of the USS Fort Jackson and offered this account: After all preparations for sending officers, crew, and ship's effects off in boats that he [Lieutenant -Commander Braine of the USS Vicksburg] and Acting Volunteer Lieutenant Williams, of the Emma, had sent, all of which I did, sending property, a list of which you will find enclosed, also a list of crew, I made preparations for her destruction as follows: I put a lighted slow match to a powder tank in the magazine and closed the door, then filled a large, fine drawer with shavings and straw taken from pillows and mattresses, partially covered it with another, and sprinkled two quarts of spirits of turpentine over all and on the woodwork around it; hung up an oilcloth from the table, one corner hanging in the shavings, which I touched with a lighted match (in the wardroom), after all the boats, but mine in waiting, had left the side, and I followed about 2:00 o'clock a.m. this morning. The explosion of the magazine containing about 200 pounds of powder occurred within half an hour afterwards, and by daylight she was 21 effectually consumed. One 12-pounder was thrown overboard, one left on the forecastle, spiked with rat-tail file, and the 24-pounder was directly over the magazine aft when it exploded, so that it was thrown into the sea (National Historical Society [NHS] 1987, ser. I, 10:343,344). Rear -Admiral S.P. Lee recommended that no action be taken to discipline the acting officer of the Violet. Lee remarked to Union Secretary of the Navy Gideon Welles, that: "Stothard is a very intelligent and efficient officer, notwithstanding this casualty" (NHS 1987, Ser. I, 10:344). Prior to its destruction, the Violet (ex -Martha) was described as a fourth -rate, wooden screw steamer measuring 85 feet in length, with a beam of 19 feet. The 166-ton tug housed one, inverted, direct -acting engine with a 30-inch diameter cylinder and one return flue boiler (U.S. Navy 1921, Ser. II, 1:233). Farther up river from the Violet wreck site there were a series of forts and batteries used as secondary defenses for Wilmington and as protection for blockade runners outbound from Smith's Inlet. Fort Lamb was located on the west side of the Cape Fear River on Reeve's Point. Above Fort Lamb was Fort Anderson, the most important of the secondary defenses. Partially built from the ruins of Old Brunswick Town, Anderson consisted of a series of trenches and earthworks approximately a mile long. Three smoothbore 24-pounders, three rifled 32-pounders and six smoothbore 32-pounders comprised the Fort's armaments. By 1864, Fort Anderson had become an inspection station for all craft heading up the Cape Fear River to Wilmington (Pleasants 1979:25). Several secondary forts, including Stokes, Lee, French, Campbell, Strong and Sugarloaf, were situated on the east side of the river (Pleasants 1979:25). In addition to this impressive array of forts, a naval construction program was initiated in Wilmington to contribute to the defenses of the harbor. The success of the ironclad ram CSS Virginia in the March 1862 battles at Hampton Roads demonstrated the superiority of armored warships to naval officers of both the North and South. In late March 1862, Confederate Secretary of the Navy Stephen R. Mallory, sent "instructions relative to gunboats" to Commander William T. Muse, the ranking naval officer at Wilmington. Shortly thereafter, the navy began building two ironclads in the city, the Raleigh at James Cassidy's shipyard at the foot of Church Street, and the North Carolina at the Beery shipyard on Eagle Island (Still 1985:5-17, 79-92). Both vessels utilized a design based on plans conceived by naval constructor John L. Porter. The plans called for a tightly framed hull, with a slight deadrise and a hard chine. The vessels were to be 174 feet long (150 feet between perpendiculars) with a draft of 13 feet. Amidships, a 105-foot long casemate, angled at thirty-five degrees and covered with 4 inches of iron plate, protected the gun deck. Two boilers provided steam for the vessel's two horizontal engines, which were geared to a single 10-foot screw. The first ironclad built on this design, the CSS Richmond, was completed in Richmond in 1862. Known as the Richmond class, this group, consisting of five vessels, was numerically the largest standardized class of ironclads constructed by the Confederacy (Holcombe 1993:63-64). 22 The two Cape Fear ironclads entered into active service by late 1863/early 1864 (North Carolina in December 1863 and the Raleigh in April 1864) after numerous delays resulting from material shortages, strikes and epidemics. However, the usefulness of these two vessels to the Confederacy's war effort was limited. Raleigh grounded on a shoal near the mouth of New Inlet and was destroyed after a sortie against the blockading squadron on 7 May 1864, less than a month after entering service. The North Carolina, on the other hand, was reduced to serving as a floating battery; its deep draft and lack of motive power rendered the vessel ineffective as a ram. The ironclad was further hampered by the use of unseasoned timber in its construction. Warping and splitting timbers caused the ship to leak incessantly and an infestation by teredo worms further weakened the hull. For most of its career, the ironclad remained at anchor near Smithville, positioned to support the nearby forts in the defense of Wilmington. The North Carolina finally sank at its moorings in September 1864. Though useless as an offensive weapon, the North Carolina served as a deterrent, preventing the U.S. Navy from entering and seizing the lower Cape Fear until the fall of Fort Fisher in the closing days of the war (Figure 15). Figure 15. Julian Davidson's "Capture of Fort Fisher" (courtesy of the NYPL). When hostilities ended in 1865 so did some of the regular river trade. The prewar steamer service between Wilmington, Charleston and Savannah was not resumed, since rail service had been established. Steamship service did, however, resume to the northern cities of Baltimore, Philadelphia and New York (Lee 1977:91). The coastal trade also revived and was conducted mainly by schooners ranging between 150 and 600 tons. Because of the decimation of American shipping during the conflict international commerce was carried in foreign bottoms, usually of British, German or Scandinavian origins (Sprunt 2005:501). Industry had been severely interrupted during the war, but was beginning to make a comeback. 23 Naval stores and lumber continued to be the principal exports with the addition of some cotton. Exports recorded for the year 1871 amounted to some 95,000 bales of cotton, 100,000 bushels of peanuts, 112,024 barrels of spirits of turpentine, 568,441 barrels of rosin, 37,867 barrels of tar and 17,963 barrels of turpentine (Sprunt 2005:513-514). Without the use of slave labor, the rice industry declined dramatically (Lee 1977:86-87). By the turn of the century, a decrease in the availability of pine trees resulted in a decline of the naval stores industry. With improvements in cultivation and transportation, cotton became a major industry in Wilmington until its decline in the 1930s. Guano from the West Indies was brought in for the new fertilizer plants. The production of creosote impregnated wood also helped increase shipping in the region (Lee 1977:87-88). During the last quarter of the nineteenth century, efforts were undertaken to develop Smithville into a port city. In 1886, the North and Southern Railroad Company announced plans to extend rail service from Wilmington to Smithville. Developers, envisioning a port that would rival Charleston and Norfolk, requested that the town's name be changed to Southport to draw attention to the "Port of the South" (Carson 1992:61). In anticipation of the expected development the town's dirt roads were paved in crushed shell and the dredge boat Woodbury began deepening and straightening the channel to accommodate increased vessel traffic. However, the proposed rail line did not materialize and Southport remained a small town relying on fishing and tourism for its economic livelihood. The Wilmington, Brunswick and Southport Railroad eventually extended a line to the town in 1911. Improvements to navigation on the Cape Fear River had deteriorated during the American Civil War. Continual silting reduced the navigable channel. By 1870, federally financed projects were again started to improve the conditions of the river. One such project was the closure of one of the two inlets. New Inlet was closed in 1881 with the belief that the increased force of the concentrated flow would sweep out the channel. The closure was accomplished by placing a rock dam that extended for more than a mile from Federal Point to Zeke's Island. The dam was completed in 1881 and later became known as "the Rocks." Another rock barrier was later built between Zeke's Island and Smith's Island. The channel depth was dredged to accommodate the deeper draft vessels (Lee 1977:91). Two life-saving stations were established near the mouth of the Cape Fear River during the 1880s. Those stations included the Cape Fear station (b. 1882) at east end of BHI and the Oak Island station (b. 1889) located west of Fort Caswell. Each station was equipped with line - throwing guns and self-righting surfboats (Sprunt 2005:527). Surf men maintained a constant vigil of the sea from the station house and conducted regular nightly beach patrols; additional patrols were conducted in daylight during stormy weather. Both stations remained active until the 1930s when newer Coast Guard facilities were constructed as replacements. On 20 July 1895, the U.S. Marine Hospital Service appropriated $25,000 for the construction of a quarantine station at Southport. The new station was to be located on the river on the east side of the channel between the upper end of Battery Island and Price's Creek Lighthouse (Carson 1992:73). The entire station was to be built on a pier 600 feet long and to consist of a 24 hospital building, a disinfecting house, attendant's quarters and a kitchen. The station opened for service by the middle of 1897 with Dr. J. M. Eager appointed as the station's first quarantine officer. A report for the fiscal year 1907 illustrates the level of activity at the station: [Eighty six] vessels spoken and passed; 19 steamers and 1 sailing vessels inspected and passed; 2 steamers and 3 sailing vessels disinfected; and 485 crew on steamers, 125 crew on sailing vessels, and 3 passengers on sailing vessels inspected. The vessels disinfected were from Bahia, Portobello, Santos, Rios, and Barbados (Brown 1974). By 1937 the station had become obsolete and was placed on caretaker status. As the facility was located on water and not a navigation hazard it was left to deteriorate and on 19 August 1951, the abandoned station was destroyed by fire (Brown 1974). The fishing industry provided the financial stamina for the economy on the lower Cape Fear during the early years of the twentieth century. The principal source of income for Southport was the menhaden fisheries. Most catches were processed into oil which was used in the manufacture of paints, linoleum, tanning solutions, soaps and waterproof fabrics (Carson 1992:96). Leftover scrap was ground up for fertilizer and feed for livestock. The Southport Fish Scrap and Oil Company and the Brunswick Navigation Company established processing plants along the Elizabeth River while additional plants could be found above the town on the Cape Fear River. World War I initiated a revitalization of the economy with the establishment of the Carolina Shipyard in May 1918. At about the same time, the Liberty Shipyard started producing steel ships as well as experimental concrete ships. The success of the shipyards was short-lived and the economy fluctuated for several years until it fell during the 1930s. Though Wilmington saw moderate success in shipping and shipbuilding after the war, most of the yards had closed by the mid- 1920s and competition from Norfolk and Charleston slowly relegated the city to an import distribution center catering mainly to regional trade (Watson 1992:145). This trade averaged 200,000 or more tons through most of the 1920s, but with the coming of the Great Depression, the amount fell to 94,007 tons by 1932 (Watson 1992:150). Wilmington's economy would not fully recover from the effects of the depression until the end of the decade. Despite this economic uncertainty, foundations were laid for future development. By the beginning of World War II, Wilmington boasted 54 wharves, piers and docks and the opening of the Atlantic Intracoastal Waterway expanded the city's trade with its hinterland and increased its role in the coastal trade (Watson 1992:148-9). With war in Europe and German submarines prowling the east coast during the early 1940s protection and defense of the coast became a top priority in Washington. The vulnerability of the Cape Fear had been confirmed during World War I and U.S. Navy officials were anxious to be prepared for future enemy intrusions (Gannon 1990:242-243). On 17 November 1941, the U.S. Navy reacquired the 248.8-acre Fort Caswell reservation, sold into private hands in 1929. The old fort grounds were to be used for training, communications and submarine tracking (Carson 1992:126). 25 The U-boat threat finally reached the Cape Fear region in early 1942. On 16 March, the 11,641-ton tanker John D. Gill was torpedoed in the coastal waters off the mouth of the river. As a result of the high number of vessel losses during the early stages of the war, defensive measures were put into place. Coastal communities were systematically blacked out, a more efficient convoy system was devised and additional planes and patrol vessels were put into service along the North Carolina coast (Stick 1952:237-239). In addition to the menace that Axis submarines and aircraft represented during the conflict, a significant hurricane struck the project area in late summer 1944. On 1 August, the tropical storm made landfall near Southport and the Oak Island coast guard station reported maximum wind speeds of 80 miles per hour. To the north, "substantial damage" occurred in Wilmington and Wrightsville Beach and the combined losses of real estate and crops amounted to two million dollars (Galecki 2005:133-134). World War II also brought renewed growth to the shipyards and relief to the area (Lee 1977:88- 90). The increased jobs and higher wages allowed Wilmington's economy to increase and become stable. After the war many of the people brought in to build ships chose to stay and make Wilmington their home. In 1945, the State Port Authority was formed, promoting ports in Wilmington and Morehead City and creating new jobs. In 1955, the military established the Sunny Point Army Terminal [Military Ocean Terminal at Sunny Point]. The facility serves as a terminal for shipping military hardware and ammunition to American forces around the globe. The base is a major employer in the area and local service and retail industries serving the military contribute to the economic prosperity of the region. By 1960, the population of Southport was reported as 2,034 residents. At that time, the town boasted a popular bookmobile, a new water tank, a "lighted" athletic field and a picnic area at the community park. Maritime news included the launch of a "big, new charter boat," the Riptide. Herman Sellers constructed the vessel for Glenn Trunnell of Southport. Other local commercial fishermen commenced discussions on the merits to install an artificial reef near the town. In September 1960, Hurricane Donna struck the region and fortunately caused only minimal damage in Brunswick County (Reaves 1999:169,172). In early February 1970, the Atomic Energy Commission approved construction of a 385 million dollar nuclear power plant to be situated north of Southport. The downtown also experienced a significant economic boost when First -Citizens corporation elected to build a bank in Southport, its first branch in Brunswick County. At the same time, waterfront interests offered services to the public such as the modern 150-seat restaurant Herman's and the new 450-foot long "fishing and pleasure pier" (Reaves 1999:243). Today, the region presents a strong economy with a state port facility that is daily frequented by international cargo vessels. The economy is further augmented by the military and commercial fisheries which provide an important source of income to area residents. In addition, Southport and the coastal communities on Oak Island and the resort on BHI are popular tourist destinations. The area's offshore waters are a sportsman's paradise catering to recreational boaters and sport fishermen alike. W Improvement History of the Entrance Channel to the Cape Fear River In 1870, the U.S. Army Corps of Engineers (USACE) initiated a project to improve navigation on the Cape Fear River. An examination of the river conducted by a commission appointed by the War Department suggested that priorities at that time should be given to closing off the channel between Smith's and Zeke's Islands (USACE 1870:70). In 1874, the closing off of New Inlet had increased the flow of water in the main navigation channel and scouring effects were noted to be deepening the channel over Bald Head Bar (USACE 1874:88-89). The officer in charge of operations also stated that a suction dredge was employed at Bald Head Bar to assist in the scouring process. Furthermore, the officer's report also noted that there were two channels into the river: a western channel with two bars (an outer with 14 feet at low water and an inner or "rip" with 10 feet at low water) and the Bald Head channel (USACE 1874:69). It was suggested that since the Bald Head channel was the natural channel all efforts should be directed towards maintaining a 12-foot level of water over it and that the western channel be disregarded. During 1889, the project was modified to provide for a 20-foot depth, at low water, from Wilmington to the Ocean. Surveys conducted during the fiscal year ending 30 June 1890 reported that the depth of water over bar had reached 16 feet (USACE 1890:131). The wreck of a Civil War gunboat was uncovered during dredging activities on the bar in 1891. The boiler from the wreck reduced water depths in the channel to 13.5 feet providing a serious impediment to navigation (The Messenger [TM] 16 May 1891). Examinations of the wreck indicated that it was a wooden -hull vessel approximately 110 tons and 100 to 110 feet long (USACE 1893 Appendix L:1451). Portions of the flue and boiler were removed by the government in 1890. On 20 May 1893, Messrs. Johnston and Townsend were awarded a contract to remove the rest of the wreck structure (USACE 1893 Appendix L:1451). The wreck site was dynamited and remaining sections of boiler recovered for disposal. Inspection of the wreck area by First Lieut. E. W. V. Lucas, E. D. Thompson and Robert Merritt revealed no trace of the hull and soundings in the vicinity indicated a depth of water of 22 feet (TM7 July 1893; USACE 1893 Appendix L:1451). The River and Harbor Act of 2 March 1907 provided for additional dredging for completing the channel to the mandated 20-foot depth level. In addition, the act also authorized for improvements in excess of 20 feet as appropriations permitted (USACE 1912:459). The project was modified again in the River and Harbor Act of 25 July 1912. Those modifications called for a channel of 26 feet deep at low water with widths of 300 feet in the river, increasing to 400 feet across the bar and in curves in the river (USACE 1912:459-460). The controlling depths of the channel were increased to 30 feet in the River and Harbor Act of 2 March 1919. In 1922, the USACE discontinued the then current entrance channel and authorized for a new one over the bar with the same dimensions as the previous one (USACE 1922:682-683). The new channel was to run in a southwesterly direction from Bald Head Point. These improvements were noted as being completed in 1932. 27 In the River and Harbor Act of 2 March 1945, the controlling dimensions for the navigation channels on the Cape Fear River were increased further. Water depths from the outer end of the bar to Wilmington were increased to 32 feet and all channels were now to maintain a width of 400 feet throughout (USACE 1945:632-631). The project was estimated to be 65 per cent complete by the end of the fiscal year. In 1950, the controlling depths over the ocean bar were increased to 35 feet (USACE 1950:653-654). Additional modifications to the navigation channels were authorized in the River and Harbor Act of 23 October 1962. Among the provisions of that Act was the deepening and widening of the entrance channel to 40 feet deep and 500 feet wide (USACE 1962:360-361). The channel was to maintain those dimensions as far as Southport were they were reduced to 38 feet deep and 400 feet wide up to Wilmington. The project was reported as being completed in 1973 (USACE 1979:6-9). Survey Data Analysis The remote -sensing survey of the JBS borrow site extension included a 200-foot perimeter buffer on all sides except the southwest. That side corresponded to the buffer included on the previously surveyed area (Figure 16). The borrow site and buffer areas were investigated on northwest to southeast survey lines laid out on 50-foot centers (Figure 17). 28 2293834 2294834 2295834 22968. co dM qr W qr cc ko qr co CD 00 + lit + N 9 + + r 8 BorrowArea H L + + 6 2 1 150 300 50 900 1,200 Feet 6 4 r i -i Iso,2s 23ft + 2293834 2294834 2295834 Figure 16.

Nine of those were located within the 200-foot perimeter buffer area. A cluster of four anomalies within the borrow area have collective signature characteristics that could represent historic vessel remains. Those four anomalies are buffered and recommended for avoidance or additional investigation. That avoidance buffer is a 300- foot-diameter circle (Figure 19) centered on coordinates presented in Table 2. 2293834 2294834 2295834 2296834 ilso+2s 23ft+(Night)+ .;rnm�sg-:1.PT t0 •� �" 1 00 U#9 + -1 ¢-1fC ' + in # # 4y "-. g A � 8 t 1 W - 6 \ -as �3 61€1-0v T2T CO Inram" + 5\` 317- # T 7 # -4 d'6T�k- .�- ii� SDI IC ' JEi 6 d 141 -7-1�D -isE 8 24 f' + CS en 2 4r 1,2ff4 Feet 6 4 P. c r 2293834 2294834 2295834 229fi834 Figure 18.

That vessel wrecked on JBS in 1665 and could well be one of the oldest known wrecks in North Carolina waters. No additional investigation of those buffered anomalies is recommended in conjunction with the proposed dredging unless the buffer could be impacted or anomaly identification is desirable. The remaining 22 anomalies within and outside the borrow area appear to have been generated by modern debris such as fish and crab traps, pipes, small diameter rods, cable, wire rope, chain, small boat anchors and possibly ordnance associated with fortifications on BHI and Oak Island. Analysis of the JBS sidescan sonar data identified only one bottom surface target (Figure 20). The signature for that acoustic target represents a linear object on the bottom surface (Figure 21). No magnetic anomaly is associated with the acoustic target. It likely represents a piling or navigation reference day board. 33 2293867 2294867 2295867 2296867 r Ln n ti A 229386i 2294861 2295867 2296861 Figure 20.

Analysis of the sub -bottom profiler data identified no geological features or targets associated with any of the magnetic anomalies. Due to shallow water and wave generated disturbance in the survey area, the EdgeTech 214 sub -bottom profiler provided less than ideal sediment profiles in the survey area (Figure 22).

Watts, Jr. Client: Olsen Associates, Inc., Jacksonville, Florida Report Title: Phase II Remote -Sensing Archaeological Survey of the Western Extremity of Jay Bird Shoals Near the Mouth of the Cape Fear River, Brunswick County, North Carolina Submittal Date: 27 September 2019 Corporate Author: Tidewater Atlantic Research, Inc., Washington, North Carolina Principal Investigator: Gordon P. Watts, Jr. Client: Geodynamics LLC, Newport, North Carolina Conclusions and Recommendations A survey of historical and archaeological literature and extensive background research confirmed evidence of sustained maritime activity associated with the Cape Fear River. That activity began in the seventeenth century and continues in the present day. Twenty-seven vessels have been documented as lost in the Smith Island vicinity. Seven have been documented as lost on the "Middle Ground" now identified as JBS. An additional nine vessels have been recorded as being lost on the bar or at the mouth of the Cape Fear River and may lie in the vicinity of the proposed borrow site. One of the earliest and most significant historically documented shipwrecks in North Carolina waters is the flyboat of Sir John Yeamans which was lost on the "middle ground" in October 1665. The Union armed -tug Violet was lost on the "western bar channel shoal" in August 1864. An 1884 U.S. Coast and Geodetic chart of the entrance to the Cape Fear (Figure 23) documented the possible location of Violet. Although USACE records indicated that elements of the steam machinery associated with a Civil War era shipwreck were removed from the channel adjacent to the shoal, archaeological evidence from other subject period shipwrecks "cleared" as obstructions has confirmed that considerable amounts of vessel structures were frequently left at sites. Among those examples are the USS Southfield (Roanoke River NC), the CSS Fredericksburg (James River VA), CSS Chattahoochee (Chattahoochee River GA), and tug Lavender (off Egmont Key FL). 36 H •7?dGC 1.I"ITC .

Several lines previously surveyed in 2007 (Tidewater Atlantic Research 2007) ran across the wreck symbol that appears on the current Cape Fear River NOAA Chart 11537-1 (Figure 24). No magnetic anomalies or acoustic targets were identified on any of the lines. Additional lines run through the wreck symbol roughly perpendicular to the planned lines also failed to produce any indication of a wreck at (or near) the site. n Al 5 /ZJ .,.�.��•.• %...

Detail of NOAA Chart 11537-1 showing mapped wreck in 2007 survey area. Twenty-six magnetic anomalies were identified in the current JBS survey data. Analysis of those data identified a cluster of four anomalies that have collective signature characteristics that could represent historic vessel remains. Those four anomalies are recommended for avoidance or additional investigation. Nine of the remaining 22 anomalies are located in the 200-foot perimeter buffer. One magnetic anomaly is located outside the current survey area. The 12 unbuffered anomalies inside the borrow area are not considered to be potentially significant. Those anomalies appear to have been generated by modern debris such as fish and crab traps, pipes, small diameter rods, cable, wire rope, chain, small boat anchors and possibly ordnance associated with fortifications on BHI and Oak Island. None of the magnetic anomalies have an associated acoustic signature. Analysis of the sidescan sonar data identified only one target. The signature for that acoustic target represents a linear object on the bottom surface. No magnetic anomaly is associated with the target. It likely represents a piling or navigation reference such as a dayboard. Analysis of the sub -bottom profiler data was not ideal due to shallow water in the majority of the area surveyed. No geological features or targets were identified in those data. Unexpected Discovery Protocol In the event that any project activities expose potential prehistoric or historic cultural material not identified during the remote -sensing survey, the dredge company under contract should immediately shift operations away from the site (or sites) and notify the respective Point of Contact for VBHI, OAI, the NCHPO (Raleigh), the NCDNCR (Raleigh), and the UAB (Kure Beach). Notification should address the exact location, where possible, the nature of material exposed by project activities and options for immediate archaeological inspection and assessment of the site (or sites). 39 References Cited and Consulted Berman, Bruce D. 1972 Encyclopedia ofAmerican Shipwrecks.

Coastal Engineering DATE: 25 July 2023 RE: Village of Bald Head Island - Borrow Site Expansion Project Geotechnical Report Dated October 2022 Pursuant to your request, the attached signed and sealed document certifies sediment compatibility of the proposed Jay Bird Shoal borrow site expansion with respect to its use as a source of beach fill at Bald Head Island, N.C. If you recall, the sediments typifying the entirety of the recipient shoreline at South Beach do not constitute a "natural beach" condition. That is to say, the subject shoreline has received approximately 12.9 Mcy of beach fill since about 2001 -- with about 77% of that volume being placed as disposal material excavated from the adjacent federal navigation project channel. The most recent federal disposal project was completed in early 2023. As directed by CAMA during the permitting of the original Jay Bird Borrow Site in or about 2007, the Applicant's engineer was directed to evaluate borrow site "compatibility" based upon the sediment characteristics of East Beach -- which to -date remains in a natural beach condition, i.e. never affected by beach fill placement. Accordingly, as you will note therein, the October 2022 Borrow Site Expansion Investigation follows that original guidance in its present- day compatibility determination. If I can provide any additional information at this time regarding the enclosed document, please let me know. Thank you.

INC- www.athenatechnologies.com Page 11 Section 1: Introduction Athena Technologies, Inc. (Athena) was contracted by Olsen Associates, Inc. (OAI) of Jacksonville, Florida to collect geotechnical vibracore samples in the vicinity of Jay Bird Shoals, which is located west of Bald Head Island in Brunswick County, North Carolina (Figure 1). The scope of the project included the collection of 10 geotechnical vibracores. Two of the vibracores were positioned in the existing permitted borrow site at Jay Bird Shoals, and the remaining 8 vibracores were located in a proposed expansion area. The scope of services also included geological logging, core photography, vibracore sub -sampling, contracting laboratory analyses, and geotechnical reporting. Vibracore sampling was conducted in July 2022; a summary of the vibracore collection methodology and findings of the geotechnical investigation are presented below. Section 2: Methodology Athena utilized the 35-foot research vessel, Artemis, to act as the sampling platform for this project. Artemis was equipped with all required US Coast Guard (USCG) safety gear and was operated by a USCG -certified, 100 Ton Master Captain. A Trimble Differential Global Positioning System (sub -meter accuracy) interfaced with HYPACK was utilized for primary navigation. Horizontal coordinates were recorded in North American Datum of 1983 State Plane Coordinate System, North Carolina (Zone 3200), U.S. Survey Feet. Real-time tide elevation data was obtained using a Champion TKO Global Navigation Satellite System receiver interfaced with the North Carolina Continuously Operating Reference Station Network, which served as the base station. During field operations, Artemis was immobilized over the desired sample sites (provided by OAI) using a triple -point anchor system. Once on station, the coordinates at the vessel location were compared with the coordinates for the desired sample location to ensure accurate vessel positioning. Upon satisfactory positioning, a water depth was collected via lead line or fathometer and final horizontal coordinates were recorded at each station. Tide elevation data were also recorded in the field and were referenced to North American Vertical Datum of 1988. Elevation data were subsequently converted to National Geodetic Vertical Datum of 1929 (NGVD 29) using the National Oceanic and Atmospheric Administration's (NOAA) VDatum software program (Version 4.4.2). A summary of the data conversion has been included as Table 1. The tide elevation data was utilized to determine the sediment surface elevation at each sample location. 1293 Graham Farm Road, PO Box 68 McClellanville, South Carolina 29458 AW H E I4A (843) 887-3800 T1_:CHIJ0L0,ff .INC- www.athenatechnologies.com FIGURE 1: Study Area Location Map 2022 Geotechnical Investigation, Jay Bird Shoals Borrow Area Expansion, Brunswick County, North Carolina A� H E IyA TECHNOLOGIES, INC. www.athenatechnologies.com NOTES: - Vibracores were collected in July 2022 VIBRACORE STUDY AREA 0 4 8 Miles IMAGE SOURCE: Sentinel 2 ESA Athena Technologies, Inc. PO Box 68 McClellanville, SC 29458 843-887-3844 Pag 13 A custom -designed and fabricated vibracore system was utilized to collect the geotechnical cores. The system consists of a generator with a mechanical vibrator attached via cable. The vibrator is attached directly to a 3-inch diameter, galvanized sample barrel. The sample barrel was lowered until the bottom of the barrel was directly above the sediment surface. The vibracore machine was turned on and the sample barrel was allowed to penetrate to a depth of -24 feet NGVD 29, or to refusal. Vibracore penetration was recorded from the deck using marked drill stems. Once the sample barrel reached the desired depth, the machine was turned off and the sample barrel was retrieved using an electric winch. The recovered core length was measured following core retrieval, and percent recovery was verified. The cores were then capped, labeled, and cut into 5-foot sections. A vibracore summary table containing final location coordinates, elevation data, and penetration and recovery lengths has been included as Table 2, and a vibracore location map has been included as Figure 2. The completed cores were opened longitudinally at Athena's core processing facility in McClellanville, South Carolina. The cores were photographed after opening and were logged by Athena's geologist in accordance with protocol outlined in ASTM D 2488 and ASTM D 2487. Draft core logs and photo -mosaic images of the cores were provided to OAI for selection of sediment sub -sample intervals. Upon receipt of sub -sample selections from OAI, Athena extracted and shipped the sub -samples to Terracon Consultants, Inc. (Terracon) in Jacksonville, Florida. Terracon is a USACE-certified geotechnical laboratory. One composite sub -sample and 2 discrete sub -samples were collected from each core. The sub -samples were analyzed for grain size distribution in accordance with ASTM D 6913 using the following sieve sizes: 3/4 in., 5/8 in., 7/16 in., 5/16 in., No. 3.5, No. 4, No. 5, No. 7, No. 10, No. 14, No. 18, No. 25, No. 35, No. 45, No. 60, No. 80, No. 120, No. 170, No. 200, and No. 230. Visual estimation of shell content was also conducted on all sub -samples using the Terry and Chilingar method (1955), and the composite samples were analyzed for carbonate content using the Twenhofel and Tyler acid digestion method (1941). Vibracore logs were developed using gINT (Version 8.2), and laboratory analytical data were incorporated into the gINT project file for statistical evaluation. A tabular summary of grain size data is presented in Table 3. Core photographs and logs have been included in Appendix A, and grain size distribution curves and granularmetric reports have been included as Appendix B. Graphs depicting percent accessory components (i.e., carbonate, gravel, silt/clay, etc.) and grain size distribution parameters (e.g., mean grain size, percent passing the No. 230 sieve, etc.) have been included as Appendix C. 1293 Graham Farm Road, PO Box 68 McClellanville, South Carolina 29458 AwHErAA (843) 887-3800 TCCHM L0 reS.IF1c:. www.athenatechnologies.com Page 15 Section 3: Discussion The vibracore study area (depicted on Figure 1) is located approximately 1 mile to the west of Bald Head Island, near the entrance to the Cape Fear River. More specifically, the vibracores were positioned southwest of the aerially exposed portion of Jay Bird Shoals, which is located northwest of the federal navigation channel entering the Cape Fear River. The mean tidal range at the study area is approximately 4.5 feet, and tidal current velocities in the channel adjacent to the study area range from 0.5 to greater than 1.5 knots during peak tidal exchange periods (National Oceanic and Atmospheric Administration). Sediment surface elevations ranged from -6.3 to -17.7 feet NGVD 29 at sample locations in the study area. Vibracore penetration depths ranged from 10.0 feet to 19.3 feet below sediment surface and recovered core depths ranged from -19.9 to -27.5 feet NGVD 29. Upon review of the data set, the cores can generally be grouped according to water depths and energy regimes from which they were collected around the study area; shallow, intermediate, and deep sample locations. Observations regarding each grouping of cores is presented below. Shallow Cores (JBS-22-01, -02, -05, and -06) • Sediment surface elevations ranged from -7 to -11 feet NGVD 29. • Cores were generally characterized by a dominance of fine-grained quartz sand with minimal silt/clay-sized constituents in the analyzed composite intervals. Silt/clay-lined burrow traces were also commonly observed in these cores. • The average mean grain size from composite sub -samples from these cores was 0.26 millimeters (mm), while the average carbonate content percentage was 9.0%. • The average percentage of fine-grained constituents (i.e., silt and/or clay -sized material) was 2.96%. 1293 Graham Farm Road, PO Box 68 4000, McClellanville, South Carolina 29458 AWHEtAA (843) 887-3800 TCCHNQL0 reS.INc. www.athenatechnologies.com Page 16 Intermediate Cores (JBS-22-03, -04, -07 and -09) • Sediment surface elevations ranged from -10 to -15 feet NGVD 29. • Tidally influenced bedding characteristics, as evidenced by the presence of interbedded quartz sand and fine-grained silt/clay, were noted below a surficial fine-grained sand interval. The depth at which the fine-grained tidal bedding was first encountered in the cores ranged from approximately -17 to -23 feet NGVD 29. • The average mean grain size in composite sub -samples from these cores was 0.17 mm, while the average carbonate content percentage was 7.4%. • The average percentage of fine-grained constituents was 3.67% and there was negligible amounts of gravel and granule -sized constituents in the sub - samples. • Although a majority of these cores terminated in sandy intervals (USCS = SP), core JBS-22-07 terminated in a fat clay (USCS = CH) interval greater than 3 feet in thickness. The CH interval was encountered at a depth of approximately -24' NGVD 29, though smaller CH and clayey sand (USCS = SC) intervals were first noted at approximately -21 feet NGVD 29 in that core. Deep Cores (JBS-22-08 and -10) • Cores JBS-22-08 and -10 were located in deepest water depths where sediment surface elevations were below -17' NGVD 29. • These cores were dominated by fine to medium -grained quartz sand with relatively high percentages of shell content. • Composite sub -samples from those cores reported the highest mean grain size and highest percentages of carbonate content, gravel -sized constituents and granule -sized constituents among all the cores. The average carbonate content from composite samples from the 2 locations was 17.3% and average mean grain size was 0.48 mm. 1293 Graham Farm Road, PO Box 68 4000, McClellanville, South Carolina 29458 AwHErAA (843) 887-3800 TCCHM L0 reS.IF1c:. www.athenatechnologies.com Page 17 • The average percentage of fine-grained was 1.61 %; very little fine-grained tidal bedding was observed in these cores. • The coarser -grained sediment characteristics in these 2 cores is likely due to the fact that they were positioned closest to the high current velocities in the main navigation channel. Discussion Regarding Laboratory Analyses It should be noted that hydrometer analysis was not conducted on the fine-grained fraction of the sub -samples. As a result, the relative percentages of silt- and clay -sized particles in each sub -sample was not established. In response, the laboratory assigned a default designation of "silt" and a liquid limit of greater than 50% to all material passing the No. 200 sieve. Lacking sufficient laboratory data to differentiate between silt- and clay - sized particles, the USCS classification assigned by Athena's geologist took precedence, when a discrepancy was noted between the laboratory USCS designation and the USCS designation in the associated core log. 1293 Graham Farm Road, PO Box 68 McClellanville, South Carolina 29458 jW"E MA (843) 887-3800 T1:CHIQ0L❑GIe=.

Hi Heather, Please find attached an updated PDF to address the below items. The narrative has been updated accordingly and I confirmed the moratorium dates should be Nov 16 to April 1 per the BO, unless there is later documentation that allows for a Nov 1 date that I haven't seen. You should have the three green cards and the fee check and the fourth notification is showing delivered per USPS tracking: I'll send a follow-up letter to withdraw the FPS application. Let me know if you have any questions or need anything further. Hope you have a good weekend.

I will keep my eye out for the check and the three green cards (with the fourth one to follow asap). And as discussed, I'd like you ask that you please also add the following to the narrative: -The date the scoping meeting was held along with the DWR 401 statements: • The project proponent hereby certifies that all information contained herein is true, accurate, and complete to the best of my knowledge and belief. • The project proponent hereby requests that the certifying authority review and take action on this CWA 401 certification request within the applicable reasonable period of time. (This should satisfy DWR's 401 pre -file requirements so they can start processing the 401 certification- but if you also directly submitted a pre -file request to DWR, please add that date as well.) -The two tables showing the mean composite size classification percentages from Erik's report (Tables 1 & 2). - Please also check the Nov moratorium date in the application. It currently proposes a start date of Nov 1 instead of Nov 16 in Section 3.1.3 of the narrative as well as in Erik's report in "Conclusions/Recommendations" on page 20. - Please include results of the recipient beach clast counts in accordance with the requirements of .0312(1)(h), if available: 15a ncac 07h .0312.pdf (state.nc.us) *If this hasn't been done yet, please add a statement recognizing that it will be done prior to construction and we can condition the permit accordingly. And please also send a formal request to withdraw the old Frying Pan Shoals major modification request (either in this modification request or in a separate email is also fine).

I've attached the vibracore logs and part of the narrative for Oak Island that addresses their JBS borrow area as well as some supplemental info they provided for the second project (adobe link below). Did you also want a copy of the permit itself? "20210622_Letter Supporting Permit Modification_with figures.pdf" at: https://acrobat.adobe.com/link/review?uri=urn:aaid:scds:US:ScOdb3e0-OcO9-4105-abc0-70ce9ef25a00 "OKI_JBS_Vibracore_JB02_JB05.pdf" at: httas://acrobat.adobe.com/link/review?uri=urn:aaid:scds:US:caba04f9-fafc-4647-a394-f60e82ebbeb4 I also just realized I don't know that I've mentioned it before, but our sediment compatibility rules have changed slightly from before and now require the (licensed) project engineer to sign off on certifying the compatibility of the borrow area. I don't think there should really be any other changes as far as the borrow area goes and you can continue to use the prior recipient beach characterization for the most part- but we will also need updated clast counts for the beach to count all sediments over 1" and shell over 3". We haven't been requiring it upfront for the application, but it will need to be done and the results provided to us at some point prior to construction (although preferably prior to permit issuance). I'll just ask that you put a statement in the narrative that acknowledges it will be done prior to construction (or when it's expected to be done prior). Please also add a statement about the scoping meeting that was held and also include your prefile date with DWR if/when that was submitted. Here's a link to the updated sed criteria rules: 15a ncac 07h .0312.adf (state.nc.us And here are the sections of it in particular: (1) The applicant shall characterize the recipient beach according to the following methodology. Initial characterizations of the recipient beach shall serve as the baseline for subsequent beach fill projects: (a) Characterization of the recipient beach is not required for the placement of sediment directly from and completely confined to a cape shoal system, or maintained navigation channel or associated sediment basins within the active nearshore, beach or inlet shoal system. For purposes of this Rule, "cape shoal systems" include Frying Pan Shoals at Cape Fear, Lookout Shoals at Cape Lookout, and Diamond Shoals at Cape Hatteras; (b) Sediment sampling and analysis shall be used to capture the spatial variability of the sediment characteristics including grain size, sorting and mineralogy within the natural system; (c) Shore -perpendicular transects shall be established for topographic and bathymetric surveying of the recipient beach. Topographic and bathymetric surveying shall occur along a minimum of five shore -perpendicular transects evenly spaced throughout the entire project area with spacing not to exceed 5,000 feet (1,524 meters) in the shore[1]parallel direction. Each transect shall extend from the frontal dune crest seaward to a depth of 20 feet (6.1 meters) or to the shore -perpendicular distance 2,400 feet (732 meters) seaward of mean low water, whichever is in a more landward position. Elevation data for all transects shall be compliant with Standards of Practice for Land Surveying in North Carolina pursuant to 21 NCAC 56 .1600. These Rules are hereby incorporated by reference, including subsequent amendments; (d) Along each transect, at least one sample shall be taken from each of the following morphodynamic zones where present: frontal dune, frontal dune toe, mid berm, mean high water (MHW), mid tide (MT), mean low water (MLW), trough, bar crest and at even depth increments from 6 feet (1.8 meters) to 20 feet (6.1 meters) or to a shore[1]perpendicular distance 2,400 feet (732 meters) seaward of mean low water, whichever is in a more landward position. The total number of samples taken landward of MLW shall equal the total number of samples taken seaward of MLW; (e) For the purpose of this Rule, "sediment grain size categories" are defined as "fine" (less than 0.0625 millimeters), "sand" (greater than or equal to 0.0625 millimeters and less than 2 millimeters), "granular" (greater than or equal to 2 millimeters and less than 4.76 millimeters) and "gravel" (greater than or equal to 4.76 millimeters and less than 76 millimeters). Each sediment sample shall report percentage by weight of each of these four grain size categories; (f) A composite of the simple arithmetic mean for each of the four grain size categories defined in Sub -Item (1)(e) of this Rule shall be calculated for each transect. A grand mean shall be established for each of the four grain size categories by summing the mean for each transect and dividing by the total number of transects. The value that characterizes grain size values for the recipient beach is the grand mean of percentage by weight for each grain size category defined in Sub -Item (1)(e) of this Rule; (g) Percentage by weight calcium carbonate shall be calculated from a composite of all sediment samples The value that characterizes the carbonate content of the recipient beach is a grand mean calculated by summing the average percentage by weight calcium carbonate for each transect and dividing by the total number of transects; (h) The number of sediments greater than or equal to one inch (25.4 millimeters) in diameter, and shell material greater than or equal to three inches (76 millimeters) in diameter shall be differentiated and calculated through visual observation of an area of 10,000 square feet centered on each transect, and between mean tide level (MTQ and the frontal dune toe within the beach fill project boundaries. A simple arithmetic mean shall be calculated for both sediments and shell by summing the totals for each across all transects and dividing by the total number of transects, and these values shall be considered representative of the entire project area, and referred to as the "background" values for large sediment and large shell material; (i) Beaches that received sediment prior to the effective date of this Rule shall be characterized in a way that is consistent with Sub -Items (1)(a) through (1)(h) of this Rule and may use data collected from the recipient beach prior to the addition of beach fill where data are available, and in coordination with the Division of Coastal Management; and (j) All data used to characterize the recipient beach shall be provided in digital and hardcopy format to the Division of Coastal Management upon request. (3) Compliance with these sediment standards shall be certified by an individual licensed pursuant to Chapter 89C or 89E of the N.C. General Statutes.

Jay Bird Shoals Borrow Site Expansion Investigation CrIVE1 JUL 2.7 20 i:� Mo,A MP SECTION WIRO JAY BIRD SHOALS BORROW SITE EXPANSION INVESTIGATION Report Submitted To: Village of Bald Head Island, N.C. Report Submitted By: Olsen Associates, Inc. 2618 Herschel Street Jacksonville, Florida 32204 October 2022 BACKGROUND Along with the strategic use of structures, the Village of Bald Head Island's Beach Management Plan has been largely dependent upon episodic beach disposal activities performed in accordance with Wilmington Harbor Sand Management Plan (WHSMP) -- as implemented by the Wilmington District, (USACOE, 2000). The latter was required pursuant to Permits and Agreements associated with the 2001 Wilmington Harbor Deepening Project. According to the tenets of the WHSMP, channel maintenance beach disposal is redirected to Oak Island — every third event. Since 2000, disposal projects have occurred on average every 2 to 3 years —principally depending upon available funding. During any extended period of the time between federal disposal projects at South Beach on Bald Head Island, the Village has been required to construct locally funded sand placements of varying sizes at South Beach necessary to maintain the beach - dune system, as well as to protect public infrastructure. To date, the main sand source for such non-federal projects at South Beach (totaling almost 3M cy) has been a permitted borrow site located on the seawardmost portion of Jay Bird Shoals (J13S) (see Figure 1). As of this date, naturally occurring borrow site recovery has been insufficient to allow for the reutilization of the original permitted borrow site area. October 2022 1 olsen associates, inc. W October 2022 2 olsen associates, inc. For purposes of developing a suitable alternate long-term sand source, the Village in 2015 initiated the geotechnical exploration, environmental analysis and marine archaeological investigation eventually required for the submittal of permits for a proposed borrow site located at Frying Pan Shoals — a large-scale depositional feature lying due south of the Cape Fear headland — and extending some 30+ miles to sea (see Figure 1). The latter shoal formation had been first investigated almost 50 years ago as a candidate source of sand by the U.S. Army Corps of Engineers Coastal Engineering Research Center (Meisburger, 1977). The estimated sand volume within the shoal was predicted to exceed some 1.4 billion cubic yards. As the result of being seaward of a major shoreline headland feature, Frying Pan Shoals receives sand annually from both South Beach and East Beach on Bald Head Island (see Figure 2). Hence, from a geological stand point it can be considered to be an ever -enlarging depositional feature. A detailed Sand Source Investigation (Olsen Associates, April 2016), concluded that a strategically sited borrow site located on the more dynamic portions of Frying Pan Shoals (within State Waters) would be subject to rapid physical recovery subsequent to any dredging event. Moreover, it was determined that both the proximity of the Frying Pan Shoals borrow site to South Beach, as well as the excellent sedimentary characteristics of the shoal sands, represent essentially an "inexhaustible" source of high -quality material for beach fill construction. Based upon the frequency of federal beach disposal projects, it was estimated that a Frying Pan Shoals borrow area would need to be utilized only every 7-10 years. Nonetheless, the initial Permit Application(s) submitted by the Village sought only a one-time use — followed by years of physical and environmental monitoring sufficient to make all impact assessments necessary to justify future use. Over the last two years, mol., Village consultants have attempted to address various regulatory agency concerns — with "potential" fisheries impacts as the final issue essentially being unresolved by early 2022. Over that period of time, various agency personnel have continually recommended that the Village continue to utilize Jay Bird shoals as the source of sand for any necessary non-federal sand placement projects at South Beach — as they had in the past (see Figure 3). October 2022 3 olsen associates, inc. Figure 2: Estimated maximum annual sediment contributions to Frying Pan Shoals. October 2022 4 olsen associates, inc. a sol� 21 z E > I14 October 2022 5 olsen associates, inc. To that end, annual survey monitoring of the Permitted Jay Bird Shoals borrow area has documented ongoing recovery of the dredged substrate — but not of sufficient spatial distribution and sediment depth where it would be suitable for near -term excavation by a hydraulic dredge. With the known eventual need for sand placement resulting from an upcoming South Beach disposal hiatus in/or about 2025 (i.e., the period when disposal sand would be contractually redirected to Oak Island pursuant to the WHSMP), the Village has recognized that any future use of the Jay Bird Shoals borrow site, as recommended by regulatory agencies, would necessitate some level of expansion of its currently permitted limits. Accordingly, that conclusion was the genesis for the formulation and implementation of the 2022 sand source investigation discussed herein. Prior comprehensive geotechnical analyses of Jay Bird Shoals had been performed for purposes of permitting two (2) dredging events (Olsen Associates, Inc.; June 2007a) and (Olsen Associates, Inc.; August 2017). EXISTING BORROW SITE CONDITIONS Pursuant to permit requirements for a 2009/10 Village beach fill project, the Jay Bird Shoals borrow site has been surveyed for purposes of monitoring its eventual long-term physical recovery. Approximately 1.8 Mcy of material was excavated during the 2009/10 project and 1.1 Mcy during a subsequent 2018/19 project. Figure 4 depicts the most recent permitted borrow site (May 2022) seabed elevations. This plot represents conditions approximately 3 years post-2018/19 project and 12 years post-2009/10 project conditions. In the plot, the full permitted borrow area limits are shown. The permitted limits are further subdivided into three sub -areas. For the 2009/10 project, only portions of Area 1 and Area 2 were excavated. For the 2018/19 project, only portions of Area 2 and Area 3 were excavated. Also plotted in the figure are the locations of two dredging exclusion zones (both located in Area 3) and a 200 ft tide gage buffer zone (Area 1 & 2). No excavation was conducted within either the exclusion or buffer zones during the 2009/10 and 2018/19 projects. Figure 5 depicts the computed seabed elevation change during the last monitoring period (May 2021 to May 2022) (Olsen Associates, Inc., 2022). For purposes of this sand source investigation, the typical limits of monitoring of the Jay Bird Shoal borrow site were modified in May 2022. That is to say, the limits of survey were extended to the north and west for purposes of documenting bathymetric features of interest adjacent to the prior dredged site (see Figure 6).

October 2022 9 olsen associates, inc. JBS BORROW AREA EXPANSION For purposes of ensuring the integrity and accuracy of numerous prior studies required for the permitting of the original 226 A. JBS borrow site (see Olsen 2017,b), the spatial limits of an expansion area have been minimized. Figures 7 and 8 depict the initial location and relative size of a preliminarily identified 75A expansion to the northwest of the original permitted site. Based upon today's bathymetric conditions, the available neat volume of borrow site sand within the expanded site above a design elevation of -22 ft. NGVD is approximately 1.4 Mcy. This is theoretically sufficient for the construction of a potential interim beach fill in/or about 2025 (including losses during fill placement). This assumes no exclusion area(s) due to potential marine archaeological concerns. By design, the maximum depth of excavation during dredging would be limited to -24 ft. NGVD — as in the prior two (2) dredging events. This ensures that beach quality sediments are excavated, as well as that the exposed borrow site post -construction substrate is suitable for expeditious benthic recovery (see LMG, June 2013). GEOTECHNICAL INVESTIGATION Having quantified potential sediment availability over depth, Olsen Associates, Inc., (OAI), authorized the acquisition of ten (10) VIBRACORES within and adjacent to the proposed 75A. expansion area. The locations of the intended cores are depicted by Figure 7. Two (2) cores were sited in previously dredged areas within Area 3 of the original site for purposes of assessing the quality of the depositional material. The firm of Athena Technologies, Inc. (Athena) was contracted to acquire the desired VIBRACORES and to log, document, and perform the requisite laboratory analyses (i.e. size characteristics, % shell, % fines, etc.). Athena completed the field work associated with VIBRACORE acquisition in early July, 2022. Each core was sampled at two discrete locations as well as a composite sample which extended over the maximum design depth of excavation (i.e. -22 ft. NGVD29 +2 ft. overdepth). Such composite samples were based upon the apparent absolute depth of visible, desirable material and verification of same based upon the results of the prior 2009/2010 and 2018/2019 projects at this general location. In addition to well defined grain size distribution analyses, the percentage carbonate material as well as fines were computed for each composite sample over depth. A brief report of findings as well as all data, photographs of cores, core logs, GDS curves, etc. are included as Appendix A to this report. October 2022 10 olsen associates, inc.

Simplistically, the expansion area material considered for future placement on South Beach (above elevation -24 ft NGVD29) is predominately fine sand classified as being predominately SP. For the cores acquired within the proposed dredged area (only), the average mean grain size is .27 mm. Carbonate percentages from the composite samples ranged from 6.0% to 19.8% with an average of 9.6%. In general, the fine grained content (based upon a no. 230 sieve averaged 2.6% for all the composite samples.

As previously well documented, it is important to understand that there are no relevant "native beach" characteristics for South Beach since it has been the recipient of the placement of over 11.5 Mcy of sediment (most from the W.H. Navigation Project channel) since 2000. In reality, the only undisturbed native beach existing on Bald Head is East Beach which faces Onslow Bay. This was recognized by the State in 2007 when the Jay Bird Shoals borrow site was first developed. Accordingly, the Village was directed to compare the borrow site characteristics to those of a limited number of composite cross -share sediment samples for South Beach and East Beach. The latter exercise was basically for "science" — since East Beach is not a proposed fill area. Standards for the determination of compatibility of borrow site material, as compared to the recipient (i.e. native) beach, are specifically defined by the State of N.C. The latter address the four (4) size classifications as well as percentage composition of calcium carbonate. Accordingly, Table 2. describes the sediment composition averages and grand means for both the recipient beach (measured 3 ways), as well as the eight cores representing the proposed borrow site expansion area. From these statistics, compatibility of the sediments to be borrowed can be determined. Table 2. Sediment Characterization for Compatibility Analysis Size Classification (% by Wt.)

For the currently analyzed JBS expansion area being proposed for excavation, the following criteria are established by the State of N.C. for purposes of determining "compatibility" of the borrow sediments relative to those of the recipient beach: a) The average percentage (by weight) of fine grained sediment (less than 0.0625mm) shall not exceed the average percentage (by weight) of fine grained sediment of the recipient beach characterization by five (5%) percent. ■ Determination • Borrow Site Av 2.6% • Recipient Beach ■ SB Mean .75% ■ EB Mean .42% ■ Grand Mean for all transects .59% ■ Result — Borrow site material complies with standard. b) The average percentage (by weight) of granular sediment (greater than 2mm and less than 4.76mm) in the borrow site shall not exceed the average percentage (by weight) of coarse - sand sediment of the recipient beach characterization plus five (5%) percent. ■ Determination • Borrow Site Av .4% • Recipient Beach ■ SB Mean 1.08% ■ EB Mean 1.37% ■ Grand Mean for all transects 1.23% ■ Result — Borrow site material complies with standard. c) The average percentage (by weight) of gravel (greater than or equal to 4.76mm) in the borrow site shall not exceed the average percentage (by weight) of gravel -sized sediment of the recipient beach characterization plus five (5%) percent. ■ Determination • Borrow Site Av .5% • Recipient Beach ■ SB Mean .07% October 2022 15 olsen associates, inc. ■ EB Mean 37% ■ Grand Mean for all transects .22% • Result — Borrow site material complies with standard d) The average percentage (by weight) of calcium carbonate in the borrow site shall not exceed the average percentage (by weight) of calcium carbonate sediment of the recipient beach characterization plus fifteen (15%) percent. ■ Determination • Borrow Site Av 9.6% .

SUBMERGED CULTURAL RESOURCE INVESTIGATION In order to determine the proposed borrow site expansion project's effects on potentially significant submerged cultural resources, OAI contracted with Tidewater Atlantic Research, Inc. (TAR) of Washington, North Carolina to conduct a magnitude and acoustic survey. The remote - sensing investigation conducted by TAR archaeologists was designed to provide accurate and reliable identification, assessment and documentation of submerged cultural resources in the study area. A copy of the TAR report in its entirety is included as Appendix B to this document. Field research for the project was conducted on 31 August 2022 and 1 September 2022. The survey was carried out with both magnetic and acoustic remote -sending equipment. Analysis of the JBS survey data identified a total of 26 magnetic anomalies (see Figure 9). Analysis of the data indicates that a cluster of four anomalies have collective signature characteristics that could represent historic vessel remains. Because JBS has a high potential for historically significant shipwrecks, those four anomalies are buffered and recommended for avoidance -- or additional investigation if the avoidance buffer could be impacted or if anomaly identification is desirable to allow dredging.

October 2022 17 olsen associates, inc. Nine of the remaining 22 anomalies are located in the 200-foot perimeter buffer which is hereby adopted by the project engineer. One magnetic anomaly is located outside the survey area. The 12 unbuffered anomalies inside the borrow area are not considered to be potentially significant. Those anomalies appear to be generated by modern debris such as fish and crab traps, pipes, small diameter rods, cable, wire rope, chain, small boat anchors, and possibly ordinance associated with fortifications on Bald Head Island (BHI) and Oak Island. None of the magnetic anomalies had an associated acoustic signature. Analysis of the sidescan sonar data identified only one acoustic target. The signature for that target represents a linear object on the bottom surface. No magnetic anomaly is associated with the target. It likely represents a piling or navigation reference dayboard. Analysis of the sub - bottom profiler data identified no geological features or targets associated with the magnetic anomalies. As graphically depicted by Figure 9, the limits of the archaeological survey extended 200 ft. (min) beyond the original 75 A expansion area limits demarcated by OAI. To that end, no anomalies were noted along the northwestern segment of the 200 ft. buffer area and only a few minor anomalies were mapped along a portion of the northeastern segment of the survey. Hence, OAI coordinated with TAR to expand the originally proposed borrow area dimensions by approximately 200 ft. and 100 ft. respectively in those two areas. It was the project engineer's opinion that by allowing dredging to occur in such areas with a greater depth of sediment — it would reduce the need for the dredge company to excavate the area closest to the navigation channel where a higher density of unknown (albeit minor) magnetic anomalies were detected. The principal investigator for TAR, Dr. Gordon Watts agreed with the project engineer's assessment in this regard. Accordingly, the originally proposed 75 A borrow site (Figure 7) was revised as shown in Figure 10. Both Federal and State permit applications will be based upon this final expansion area footprint which now encompasses 72.8 A. October 2022 18 olsen associates, inc. wr LVI Zj s! ' °h° o 0 0 0 0 o .

October 2022 19 olsen associates, inc. CONCLUSIONS/RECOMMENDATIONS It is recommended that the Village of Bald Head Island seek a modification of CAMA 91- 14 and USACE No. SAW-2012-00040 sufficient to expand a portion of a previously developed borrow site located at Jay Bird Shoals. The intended project volume required is estimated at 1 Mcy, mol. All sand would be placed on the two ends of S. Beach. The proposed timing of the work would be between 1 November and 1 April of the following year. Work would be performed by a cutter suction dredge with direct deposit on S. Beach by pipeline. It is anticipated that a submerged pipeline can cross the federal navigation project without the need for burial, i.e. seabed placement below the authorized channel depth of -44ft. MLW. As discussed herein, the footprint of the 72.8 A expansion area was slightly revised to minimize direct or indirect impacts to potential cultural resources. Prior dredging projects at Jay Bird Shoals had done similarly based upon marine archaeological investigations by Tidewater Atlantic Research, Inc. (TAR, 2007). Permits for a subject 1 Mcy, mol "placement volume" (measured in place), will seek a borrow site design depth of -22 ft. NGVD29, with a conventional 2 ft. overdepth "tolerance". Direct placement of hydraulic fill on South Beach will be by pipeline utilizing a 24"-30" cutter suction dredge. Although the permitted area is 72.8 A, the design plans will encourage most excavation to occur along the northwesternmost portion of the site so as to reduce the actual acreage of seabed disturbed. Based upon prior numerical modeling investigations of various Jay Bird Shoals borrow site configurations (Olsen Associates, Inc., 2007b and Olsen Associates, Inc., Feb. 2013), it is the project engineer's opinion that the expansion of the Jay Bird Shoals discussed herein will not result in any meaningful changes to the areawide Wave Climate or littoral transport rates or patterns.
