Archaeological Report Management Summary Entitled: Remote -Sensing Reconnaissance Survey at the Location of A Proposed Borrow Site on Frying Pan Shoals Off Bald Head Island, Brunswick County, North Carolina Submitted to: Olsen Associates, Inc. 2618 Herschel Street Jacksonville, Florida 32204 Submitted by: Gordon P. Watts, Jr., Ph. D, RPA Principal Investigator Tidewater Atlantic Research, Inc. P. O. Box 2494 Washington, North Carolina 27889 31 July 2016 Abstract Olsen Associates, Inc. (OA) is the project engineer representing the Village of Bald Head Island, North Carolina in its efforts to control erosion along the south shore of Bald Head Island at the mouth of the Cape Fear River. In order to provide an initial assessment of the potential effects of borrowing nourishment material from Frying Pan Shoals on potentially significant submerged cultural resources, OA contracted with Tidewater Atlantic Research, Inc. (TAR) of Washington, North Carolina to conduct a 2015 reconnaissance magnetometer survey of the proposed borrow site at 100-foot line spacing. Field research for the project was conducted on 27 and 28 April 2015. Analysis of the magnetic remote -sensing data generated during the reconnaissance survey identified a total of 34 magnetic anomalies. Twenty-two of those magnetic anomalies lie in the 2016 survey area. Those data and data from a geophysical survey led to refining the proposed borrow site. On 20 and 21 July 2016, TAR carried out a second remote -sensing survey to generate sufficient magnetic and acoustic data to support a submerged cultural resource assessment. That survey identified 39 magnetic anomalies. Sonar produced no evidence of material exposed on the bottom surface. Based on those data a single buffer that encompasses four magnetic anomalies identified in 2015 and five magnetic anomalies identified in 2016 is recommended. The remaining magnetic anomalies in the 2016 survey area all resemble single object sources and do not appear to represent a potentially significant submerged cultural resource. None of those anomalies are recommended for avoidance and no additional investigation is recommended in conjunction with the project as proposed.

(OA) is the project engineer representing the Village of Bald Head Island, North Carolina in its efforts to control erosion along the south shore of Bald Head Island at the mouth of the Cape Fear River in Brunswick County. A borrow site on Frying Pan Shoals is the recommended source. In order to provide an initial assessment of the potential effects of borrowing nourishment material from Frying Pan Shoals on submerged cultural resources, OA contracted with Tidewater Atlantic Research, Inc. (TAR) of Washington, North Carolina to carry out a reconnaissance -level marine survey of the proposed borrow area in 2015. In 2016, OA again contracted with TAR to carry out a follow-up remote -sensing survey of a revised final borrow site. That survey included both magnetic and acoustic remote sensing to generate sufficient data to support an assessment of potential impacts on submerged cultural resources. The 2016 remote -sensing investigation conducted by TAR archaeologists was designed to provide accurate and reliable reconnaissance -level identification, assessment, and documentation of submerged cultural resources in the proposed borrow 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. The results of the investigation were designed to furnish OA with the archaeological data required to comply with submerged cultural resource legislation and regulations. TAR carried out the 2016 survey of the proposed borrow site at 100-foot and 50-foot line spacing. The 100-foot 2016 lines were designed to fall in between the 2015 lines and with additional 50-foot lines in new areas this provides 50-foot line spacing throughout the revised borrow site. Field research for the initial reconnaissance survey project was carried out on 20 and 28 April 2015. The second remote -sensing survey was carried out on 20 and 21 July 2016. Analysis of the magnetic remote -sensing data generated during the 2016 Frying Pan Shoals survey identified a total of 39 magnetic anomalies. Sonar produced no evidence of material exposed on the bottom surface. A total of 22 of the magnetic anomalies identified in 2015 lie within the revised borrow site perimeter. Based on the 2015 and 2016 data, a single buffer that encompasses four anomalies identified in 2015 and five anomalies identified in 2016 is recommended. The remaining anomalies 2015 and 2016 anomalies in the 2016 revised survey area all resemble single object sources. None of those appear to represent a potentially significant submerged cultural resource. Project personnel consisted of Principal Investigator Gordon P. Watts, Jr., and Remote -Sensing Operator Richard Dentzman. Dr. Watts analyzed the remote -sensing data. Dr. Watts and Senior Historian Robin Arnold prepared this management summery. 2 Project Location The current remote -sensing project area is situated on the south side of Frying Pan Shoals approximately 8,800 feet south of the southeast point of Bald Head Island. The area surveyed was polygon in shape measuring approximately 5,200 feet in length [south to north] and 4,100 feet in width [east to west] (Figure 1). s' e 4 a 0 + 15 36 ` SO4uV1 4 1 9aensrs + dd 25 FA +. k •2 .

Remote -Sensing Survey In order to reliably identify submerged cultural resources, TAR archaeologists conducted a systematic 50-foot line spacing remote -sensing survey covering the proposed 2016 borrow site. Underwater survey activities were conducted from the 25-foot survey vessel Atlantic Surveyor. In order to fulfill requirements for the initial reconnaissance survey, only magnetic remote - sensing equipment was employed. Because magnetic remote sensing alone does not fulfill the requirements for a cultural resource survey, additional lines were run with both magnetic and Ld acoustic remote -sensing equipment during the second investigation. Data collection during both investigations 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. 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 just below 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. Magnetic data from both surveys were contour plotted using QUICKSURF software to facilitate anomaly location and definition of target signature characteristics. All magnetic data were correlated with sonar records. Figure 3. Launching EG&G Geometrics G-881 cesium vapor magnetometer. A Klein 3900 450/900kHz high -resolution digital sidescan sonar was employed to collect acoustic data in the 2016 survey area (Figure 4). During the survey, the sidescan sonar transducer was deployed and maintained at approximately 5 feet below the water surface during data acquisition. Acoustic data was collected along transects spaced on 100-foot intervals in the previously covered area and 50-foot intervals in new areas. Sonar range scales were selected to provide a minimum of 200% coverage of the 2016 survey area and generate high target signature definition. Sonar data was recorded and tied to the magnetic data by regular DGPS annotations. 5 ���W - Y� _ NOW Figure 4. Klein 3900 sidescan sonar used to image the bottom surface. A TRIMBLE AgGPS was used to control navigation and data collection in the survey area. That system has an accuracy of plus or minus three feet, and can be used to generate highly accurate coordinates for the computer navigation system on the survey vessel. The DGPS was employed in conjunction with an onboard laptop loaded with HYPACK navigation and data collection software (Figure 5). Positioning data generated by the navigation system were tied to magnetometer records by regular annotations to facilitate reliable relocation location and anomaly analysis. All data is related to the North Carolina State Plane Coordinate System, NAD 83. Figure 5. Computer navigation system located at the research vessel helm. on Data Analysis To ensure reliable target identification and assessment, collection and analysis of the magnetic data was carried out using HYPACK survey software. Magnetic data generated during the survey was reviewed in HYPACK to identify anomalies and contour plotted at 5-gamma intervals for analysis and accurate location of the material generating each magnetic anomaly using QUICKSURF contouring software. Magnetic anomalies were isolated and analyzed in accordance with intensity, duration, areal extent, and other signature characteristics. Each line of sonar data was reviewed using SONARWIZ software from Chesapeake Technology. Reviewed data was systematically examined for targets on the basis of configuration, areal extent, elevation, target intensity and contrast with background and shadow image and were also reviewed for possible association with identified magnetic anomalies. Sonar data was mosaiced in SONARWIZ to confirm coverage, assist with analysis and provide report illustrations. Data generated by the remote -sensing equipment was developed to support an assessment of each magnetic anomaly and/or acoustic signature. Analysis of each signature included consideration of magnetic and sonar signature characteristics previously demonstrated to be reliable indicators of historically significant submerged cultural resources. Assessment of each anomaly includes identification of those that merit avoidance options and possible buffer recommendations to avoid potential cultural resources. Where avoidance is not possible the assessment will include recommendations for additional investigation to determine the exact nature of the cultural material generating the signature and its potential National Register of Historic Places (NRHP) significance. Historical evidence is being developed into a background context and an inventory of shipwreck sites that identified possible correlations with potentially significant magnetic anomalies. A magnetic contour map of the survey area will be produced to aid in the analysis of each anomaly. All magnetic anomalies are listed and described in Appendix A. Description of Findings Analysis of the magnetic remote -sensing data generated during the 2016 Frying Pan Shoals survey identified a total of 39 magnetic anomalies. A total of 22 of the magnetic anomalies identified in 2015 also lie within the revised borrow site perimeter (Figure 6). Sonar produced no evidence of material exposed on the bottom surface (Figure 7). Based on the 2015 and 2016 data, a single buffer that encompasses four anomalies identified in 2015 and five anomalies identified in 2016 is recommended. That buffer includes: 2015 anomalies 010-1-mc-18.2g-352.1f, 013-1-mc-82g-363.5ff, 014-4-nm-2.5g-34.8f and 014-5dp- 14.9g-92.7f, and 2016 anomalies 029-1-nm-15.3g-124f, 031-1-dp-10.9g-121.8f, 035-1-me-7.8g- 147.9f, 037-1-mc-7.3g-205.1f, and 039-3-dp-24.6g-117.5f. That cluster of anomalies includes several multi -component signatures and a geographical association that could be associated with small vessel remains and an associated scatter of debris. For that reason, the anomaly cluster is buffered and recommended for avoidance (Figure 8). 7 231)ON 2314DOO 2315000 2316004 2317�00 0 �p-34p-f 53 d7PL)_ I■ .S e! ■ 4. a -0pr-��F1Sfa 4.j-'1 r.2e - * i n 9111-.p7 m.20T99'7T67.670 F ,1•dp•389g-2iF1�"73.2Py71{0g1t-l•I arIrCr2-I9yF7+ .,s'-rn. rar,0l IS' 3 �*.f 0#*013-,. „- 144n a 95? i&39eF dp1d409�4.1D 4-.5-ft.1:4iy gFpts;.afu777I G1f�-01h#-11 r-�.._• W-2-pp -,2 W 041.2-"4-6 SQ-749r 047-1 +55.20-,4 �dw5-?pm•7pap7F 06 r.,-n�3 7p-3T.S! nrJ 2?rn-1, Iq�B 2F a2a 3dp'.7 LI 057-1-p—ME9424 l•21u7ti10.dIp EO-1fi}3�.iym i' 51F 067-1-dp- 1p-50 d}17.0 307f`2L I p, 6pp 3 ct0i:-2 � R934 ]t 1•Ad -o+45 �2 *OB 1 dp 23p• 01-I-dp-5 1-K * 4h + -,ilm 2.20-4& 00.1 •dco W-2 13 54A2 if QB73--,ao-+B 6f 7 :.,.' , L" 4. -- S C 1.d1w 3% 40 p6f OB3-1�p-2 _ IP ■ PA f a # p M hO�Snm Fi -74 ip 0 312.5 625 3,25Q 1.875 2,5W Feet #1#OOb 231d00b 231Sf}00 2316088 2#f7660 2 0 O G N Figure 6. 2016 survey area with 2015 and 2016 magnetic anomalies and recommended buffer. 2313000 2314007 2315000 231U00 23,71,00 3 y 0 3125 625 1.250 1.875 2,500 Feet 23738A� #31ddA6 2315ad8 2316�6 fed _ r i.

Recommended buffer for potentially significant anomalies. 10 The remaining anomalies in the 2016 survey area appear to be generated by small single objects such as pipe, traps or small boat anchors. Several more moderate signatures could also represent larger pipe cable, chain, or larger vessel anchors. None of those appear to represent a potentially significant submerged cultural resource. Those anomalies are not recommended for avoidance and no additional investigation is recommended in conjunction with the project as proposed. Conclusions and Recommendations Historical and archaeological literature and background research confirmed evidence of sustained historic maritime activity associated with the Bald Head Island and Cape Fear River area that continues in the modern era. Documented transportation activities in the vicinity of Bald Head Island and neighboring waterways date from the first half of the sixteenth century. The Cape Fear River region became a focus for European activities as early as 1526 when Vasquez de Ayll6n led an expedition from Florida into the Cape Fear region. Permanent settlement along the banks of the Cape Fear River began during the second decade of the eighteenth century. As a consequence of nearly 400 years of navigation in the coastal region of Brunswick County and settlement along the banks of the Cape Fear River since the eighteenth century, there is a high probability that historically significant submerged cultural resources are located in the area. Although three wrecks are charted in the immediate vicinity of the proposed borrow site on NOAA Chart 11536, no remote -sensing evidence of vessel remains was apparent at those locations. While that is not unusual, buffered material in the project area could be associated with the remains of one or more of those wrecks. While no shipwrecks in the project vicinity have been listed on the NRHP or with the North Carolina Underwater Archaeology Branch [UAB-Fort Fisher NC], previously identified vessel remains document that they exist, and there are at least 27 shipwrecks recorded in the coastal waters near Bald Head Island and the mouth of the Cape Fear River. Because of their association with the broad patterns of North Carolina history, the remains of sunken vessels preserve important information about the maritime heritage of the North Carolina coast. In the event that the buffered anomalies can be avoided, no additional investigation is recommended in conjunction with the proposed project. None of the un-buffered anomalies have signature characteristics similar to those associated with historical vessel remains and no additional investigation is recommended for cultural resource assessment. However, if the buffer cannot be avoided, additional investigation should be carried out to identify the source of those anomalies and assess the NRHP significance of material generating those signatures. In the event that historical vessel remains or other archaeological sites are identified during the course of proposed dredging, the dredge contractor should be required to immediately shift its operations to a different area and immediately notify the respective Point of Contact for the Village of Bald Head Island, OA, and the UAB [representing the North Carolina Department of Natural and Cultural Resources] of the situation.

PROJECT DESCRIPTION Bald Head Island is part of an island group known as Smith Island, located east 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 along the western side of Frying Pan Shoals located approximately a mile southeast of Bald Head Island (and the Shoals Club). The proposed area encompasses approximately 188.7 acres of an overall borrow investigation site of 460 acres. The project disposal area extends the entire stretch of South Beach, which is located within the Ocean Erodible Area of Environmental Concern (AEC). The annual erosion rate for the project area ranges from 2' to 10.5'/year per the Division of Coastal Management's 2013 Annual Erosion Rate maps. The Coastal Resources Commission established the erosion rate at the westernmost end of the disposal area (at the Point) and on West Beach in 2009 by Declaratory Ruling. 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 slightly east of the historically placed limits of the federal project. South Beach last received sand under the federal project in the winter of 2014/2015, and under the Village -sponsored project (Permit # 91-14) this past winter through dredging of Jay Bird Shoals. State Permits #9-95 & #67-09, both issued to the Village of Bald Head Island, have also authorized nourishment of South Beach. 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. 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 Frying Pan Shoals as a one-time beach maintenance borrow site, with associated beach nourishment at South Beach, Bald Head Island. The application states 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 to mitigate erosion on South Beach. While the Environmental Impact Statement (EIS) for the terminal groin project identified Frying Pan Shoals as a potential sand source, Jay Bird Shoals was identified as the preferred borrow area for initial construction and subsequently used for the first associated nourishment event. A Major Modification application request was previously submitted for the first post -construction maintenance nourishment event, however significant concerns were expressed by agencies regarding the use of Frying Pan Shoals during review, which led to the NOR;7�CARC� DeWdeM d Emimnme WQ-11ty North Carolina Department of Environmental Quality j Division of Coastal Management Wilmington Office 1127 Cardinal Drive Extension I Wilmington, North Carolina 28405 910.796.7215 Village of Bald Head Island Major Modification to State Permit No. 91-14 Frying Pan Shoals Beach Nourishment Project Page Three applicant's reevaluation of sand sources and subsequent use of Jay Bird Shoals, as previously utilized for a Village nourishment project under State Permit 67-09. The application discusses alternative borrow area sand sources, such as Jay Bird Shoals and Middle Ground, the Bald Head Creek shoal complex, the three segments of the federal inner -ocean entrance channel near Bald Head Island, the Offshore Dredged Material Disposal Site (ODMDS), and multiple confined disposal facilities in the vicinity, but ultimately all were rejected as unsuitable sites. A discussion of alternate sand source sites was included in the application (see pages 7-12 of the Narrative). According to the applicant, Frying Pan Shoals contains an approximately 460-acre sand source (as investigated by the applicant) on the western portion of the shoal located approximately 1 mile seaward of the southeastern shoreline of Bald Head Island (see Sheets 1, and 4-7 of 9). According to multiple Vibracores analyzed for sand quality (see Appendix D- Geotechnical Report/Frying Pan Shoals Sand Search Investigation), the applicant has determined that composite samples from the borrow site taken to a maximum depth of — 25' Mean Low Water (MLW) contain 92.09% mean sand content and an average of 2% fines (see Appendix D and Narrative). While the sampling performed does not meet the technical standards for beach fill projects described in 15A NCAC 07H .0312, as sample spacing requirements were not met throughout the borrow area, the Regulatory Reform Act of 2016-2017 was passed by the General Assembly (SL 2017-10). The legislation included language that exempted the State's cape shoals, including Frying Pan Shoals, from the technical standards of beach fill projects. The applicant has stated that the Sand Search Investigation characterizes the nature and quality of the material contained within the proposed borrow site. The application states that the proposed borrow site could provide 3.995 million cubic yards of compatible material if excavated to a depth of -25 ft. NAVD88 and 2.487 million cubic yards of material if excavated to a depth of -20 ft. NAVD88. The narrative characterizes the viability of the borrow site as a potential sand source due to numerous factors including accessibility, presence of high quality beach compatible sediment, ability to avoid cultural resources and a statement that the area is highly dynamic and highly depositional (see Appendix D and Narrative). A brief statement on expected borrow site recovery for Frying Pan Shoals is included in the Narrative (see page 15), although no data or modeling results are presented. The application states that excavation would be conducted to a maximum depth of -21 ft. NAVD88 with -2 ft. overdepth (see Sheet 8 of 9) utilizing a 27"-30" cutter suction dredge. A submerged pipeline would provide disposal on the South Beach shoreline. According to the applicant, existing water depths the overall borrow area range from -15 to -5 NAVD88 (See Sheet 8 of 9). Hydrographic surveys and a marine cultural resource investigation have identified a buffer exclusion area within the proposed sand source footprint measuring approximately 9.7 acres that would be avoided (see Narrative and Sheets 7 and 9 of 9). 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 biennially 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 NOR;7�CARC� DeWdeM d Emimnme WU-11ty North Carolina Department of Environmental Quality j Division of Coastal Management Wilmington Office 1127 Cardinal Drive Extension I Wilmington, North Carolina 28405 910.796.7215 Village of Bald Head Island Major Modification to State Permit No. 91-14 Frying Pan Shoals Beach Nourishment Project Page Four calculate deposition rates or "recharge" of the site as part of the existing BHI comprehensive Shoreline Monitoring Program, which is reported annually. The proposed limits of the beach fill template would extend from Station 48+00 to Station 218+00 on South Beach, with a potential taper to Station 220+00. The applicant states that the beach construction berm would conform to the previously authorized maximum berm elevation of +8.5' NGVD29. The beach profile would have an average width of 350 linear ft. over the length of the entire 17,000' disposal template area and would include a 20H:1 V slope (see MP-2 and Sheets 2 and 3 of 9). According to the applicant, an estimated 98 acres of fill (-800,000 cubic yards) would be placed below mean high water. The proposed beach fill project would excavate up to 2.5 million cubic yards of material. It is estimated that the identified Frying Pan Shoal Site has a maximum compatible volume of 8.5 million cubic yards of material available for long-term use, but the applicant acknowledges any future events would be coordinated through an additional permit application. 10. ANTICIPATED IMPACTS: The proposed excavation of the Frying Pan Shoals Borrow site could result in the excavation of up to 188.7 acres of Public Trust Area and Estuarine Waters. The subsequent beach disposal would result in the filling of approximately 39 acres of unvegetated beach above MHW and approximately 98 acres of area below MHW. Increases in turbidity should be expected during construction. The applicant has stated that because the borrow site is a highly dynamic and renewable shoal feature, physical and biological disturbances should be minimized. While no data or modeling results were presented to support the assertion, the applicant has committed to physical monitoring of the borrow site. The application states that the Village of Bald Head Island will be responsible for any dune revegetation or stabilization that is deemed necessary by agencies in a separate contract and visual surveys of escarpments and remediation would be conducted prior to turtle nesting season. The applicant states that work would occur during the winter months to reduce biological impacts.

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 ongoing chronic annual erosion resulting in predictable sand losses and associated shoreline recession. Severe erosion has been chronicled along South Beach (particularly its western reach) since the 1970s. According to a recent detailed physical monitoring report, Olsen Associates, Inc. (2018), the firm computed that the Island's gross volumetric sand loss (excluding East Beach) over the November 2000 to May 2018 timeframe was approximately 6.78 Mcy (corresponding to an average annualized loss of 387,500 cy). The highest rates of sand loss have occurred principally at the extreme west end of South Beach in the vicinity of the Cape Fear River Entrance. Ultimately, this prompted the Village of Bald Head Island (Village) to procure authorizations for, and subsequently construct, a 1,300-If terminal groin at that location. Construction of the terminal groin structure was completed in December 2015. While the terminal groin has successfully addressed chronic shoreline recession trends along the westernmost South Beach shoreline directly abutting the federal navigation project, it is acknowledged that the terminal groin and an existing sand tube groin field (located eastward thereof) are not sufficient, in and of themselves, to prevent or to adequately offset sand losses from South Beach in its entirety. As a result, periodic nourishment through both the federally -sponsored Wilmington Harbor channel maintenance and disposal project, as well as Village - sponsored "engineered" beach projects, have been (and will continue to be) required to mitigate erosion along the entirety of South Beach. Hence, the long-term and recurring threat to existing homes, dunes and infrastructure (as a result of both man-made and storm -induced erosion and consequential shoreline recession) has required the Village to evaluate and develop long term sand source options deemed suitable for erosion control. 3.1.2 Description of Borrow Site Alternatives Areas considered as potential sources of suitable material for beach nourishment have been evaluated in the context of the project requirements (both in terms of sand quality and quantity). Generally, sand source areas must consist of sediments satisfying minimum standards for beach fill projects as stipulated by the North Carolina Administrative Code (15A NCAC 07H.0312 Technical Standards for Beach Fill Projects)'. The applicant must also consider the proximity of the source area relative to the area of beach being nourished due to transport logistics, project duration, constructability, and cost constraints. All dredging and beach filling operations must be confined to a relatively narrow window of time to minimize potential adverse effects to environmental resources. In light of these considerations, the most desirable potential sources are identified in the general vicinity of West Beach and South Beach on Bald Head Island. 1 Notably, Frying Pan Shoals (FPS) is exempt from the sediment criteria rules. SL 2017-10 specifies that until the North Carolina Coastal Resource Commission (CRC) adopts rules exempting cape shoal systems from the Sediment Criteria Rule, it is required to "exempt from the permitting requirements of the Sediment Criteria Rule and any sediment in the cape shoal systems used as a borrow site and any portion of an oceanfront beach that receives sediment from the cape shoal systems," including from FPS. SL 2017-10 section 3.15(b) and (c). Major Modification to CAMA Permit # 91-14 — March 2020 South Beach Renourishment Project Village of Bald Head Island, Brunswick County, North Carolina 7 The Applicant, in coordination with the project engineer, evaluated several borrow site alternatives prior to the design of the proposed Frying Pan Shoals borrow site. The following sites were considered as part of the alternatives analysis: (1) Nearshore Inlet Shoals (including Jay Bird Shoals and Middle Ground); (2) Wilmington Harbor Entrance Channel (Inner Three Reaches); (3) Bald Head Creek Shoal Complex; (4) Offshore Ocean Dredged Material Disposal Site (ODMDS); (5) Confined Disposal Facilities; and (6) Frying Pan Shoals. A map of the approximate location of alternatives evaluated for potential sand source sites is provided in Attachment A. Alternate Borrow Areas within Nearshore Inlet Shoals fincludine Jav Bird Shoals and Middle Groun In January 2017, the Village submitted state and federal permit applications for the proposed dredging of a borrow site on Frying Pan Shoals (FPS). In consideration of the concerns raised by National Marine Fisheries Service (NMFS) and their accompanying recommendation to first explore other viable sand -source alternatives, the Village further evaluated the potential to prioritize the use of the previously authorized borrow site located on Jay Bird Shoals (JBS) (including both the partially recovered area dredged in 2009 and any remaining, undredged portions of the permitted borrow site at that time). The Village had identified the JBS borrow site as the only other viable alternative borrow area available for near term sand placement at Bald Head Island (BHI). Within the developed JBS borrow site, there was an estimated 900,000 cy of sand remaining in the undredged portion of the site and lying outside a Cultural Resource Exclusion area. Additionally, there was some volume of sand available which was within the area previously excavated in 2009. The Village -sponsored nourishment project in 2018/19 proposed the placement of approximately 1.2 Mcy. As a result, sand reserves within the JBS permitted site were sufficient to meet the nourishment volume required for the 2018/19 project. However, dredging beyond the previously developed borrow site limits could eventually induce significant impacts to the JBS shoal feature. For instance, more expansive dredging within the shoal feature could affect wave climate and tidal flows to such an extent that that it could adversely impact the shoreline of Caswell Beach and Fort Caswell on Oak Island, as well as West Beach on Bald Head Island. Due to the identified potential for adverse impacts, the design and implementation of a more expansive borrow site on JBS necessary to meet the long-term sand needs on South Beach is not feasible. Other ebb tidal shoals near the mouth of the Cape Fear River include Bald Head Shoal and Middle Ground. Similar to JBS, these depositional features generally exhibit high sand content in sufficient quantities to provide the necessary amount of nourishment to offset the sand losses on South Beach under consideration. However, these shoals play an important role in the dissipation of storm wave energy affecting the beaches along Oak Island and Bald Head Island. In addition, the shoals provide intertidal and subtidal habitat supporting estuarine and marine fauna. Dredging from Bald Head Shoal is predicted to be highly detrimental considering ongoing changes at that nearshore location due to the navigation channel reorientation, as well as the proximity and important beneficial sheltering effects of this depositional feature to the currently eroding Bald Head Island beaches. In a similar fashion, major nearshore modifications to Middle Ground could affect littoral processes at Oak Island. Middle Ground is the most practicable sand source for cost-effective future beach restoration on Oak Island even though it is not considered a high probability sediment source for work at Bald Head Island. To that end, the Town of Oak Island has recently (January 2020) submitted permits to develop a borrow site within Middle Ground. As a result, Major Modification to CAMA Permit # 91-14 — March 2020 South Beach Renourishment Project Village of Bald Head Island, Brunswick County, North Carolina N the Town of Caswell Beach has requested that Oak Island provide post -construction monitoring and stipulate to the mitigation of damages resulting from the dredging of the borrow site — should such occur. Additional removal of material from these two areas to offset sand losses on Bald Head Island (or Oak Island) would provide temporary benefits at best with the likelihood of reducing beneficial effects in their lee on one or both of the two adjacent barrier islands. Hence, "over -utilization" of these potential sand sources is not recommended and in all probability would be strongly opposed by interests on the east end of Oak Island. Wilmington Harbor Entrance Channel By way of Permit Condition #60 of Department of Army (DA) Authorization of the Terminal Groin Project (Action ID No. SAW-2012-00040), the Village must evaluate the Wilmington Harbor Entrance Channel as a potential borrow site for the maintenance of the groin fillet. To that end, the Village evaluated the use of the federal channel reaches for borrow material as part of the Village -sponsored 2018/19 beach nourishment project. Since all sand dredged by the Corps of Engineers (COE) in 2017/18 as part of their regularly occurring channel maintenance was placed on Oak Island pursuant to the Wilmington Harbor Sand Management Plan (WHSMP), there was not sufficient sand quantities available to the Village for their project. Similarly, the timing of future COE channel maintenance projects makes it difficult to design, permit, and contract a Village -sponsored project within the federal channel with any level of certainty of sand volumes and locations. This assessment was corroborated by the Wilmington District Engineering staff as part of a Section 408 Permit analysis in May 2018 required by the Villages' 2019 1.2 Mcy fill project. At that time, the District determined that dredging of the navigation channel was not a "practicable" option for beach maintenance on Bald Head Island. Moreover, pursuant to the WHSMP, the navigation channel disposal sand is presently scheduled for episodic placement on Oak Island beaches every third maintenance event. Bald Head Creek Shoal The previously permitted and dredged borrow site of the ebb tidal shoal of Bald Head Creek (BHC) is limited in size and sand volumes to be able to address long-term sand needs of South Beach. Given its location and relatively small quantity of sand available and the shallow depth of dredging required at that location, the BHC borrow site is better suited for small volume requirements at West Beach. Moreover, only a small shallow draft dredge can be utilized at that location. Therefore, the Bald Head Creek site is not suitable for any large-scale nourishment event on South Beach. Areas within Former Federal Channel Offshore sediment data acquired from areas situated within the former federal channel alignment at the mouth of the Cape Fear River indicate a high content of fine sediments generally considered unsuitable for beach nourishment. Due to the nature of this depositional material and the technical standards for beach placement, this alternative is determined not to be practicable and is therefore eliminated from further consideration. Offshore ODMDS The offshore ODMDS has been used for the disposal of dredged materials from the Wilmington Harbor Federal navigation project and the Military Ocean Terminal at Sunny Point (MOTSU) for many decades. MOTSU is a military port facility located on the west bank of the Cape Fear River approximately 10 miles upstream from the river's mouth. Both the Federal navigation project and MOTSU require some level of annual maintenance dredging. Reaches of the Federal project maintenance extend from the ocean bar channel at the mouth of the Cape Fear River to a point just north of Smith Creek on the Northeast Cape Fear River (north of Wilmington, NC). The Wilmington Harbor Dredged Material Management Plan (DMMP) provides specific information as to the historical and present-day use of the ODMDS including documentation of the quantity and character of material Major Modification to CAMA Permit # 91-14 — March 2020 South Beach Renourishment Project Village of Bald Head Island, Brunswick County, North Carolina 0 placed within. In addition, an evaluation of potential beneficial uses of material dredged from the Federal navigation project is required as part of the DMMP. This requirement served as the premise forthe establishment of the 2000 Wilmington Harbor Sand Management Plan (SMP) which specifically provides for the return of littoral material to the beachfront. According to the SMP, beach -compatible dredged material (sands) dredged from the ocean bar or river navigation channel should be placed on nearby beaches or within the active littoral system when it is economically and environmentally acceptable to do so. The DMMP clearly documents conditions of the two ODMDS sites (both the old site used until 2002 and the new site used for current dredged material disposal). Specific volume totals of dredged materials placed within the former ODMDS site are available from 1976 through 1999 (Table 1). Since 1987, the date of the site designation, approximately 27.6 Mcy of dredged materials have been placed within the ODMDS. The source of the material is divided into three general zones within the Cape Fear River: (1) the Wilmington Harbor Federal navigation project, ocean bar channels (WH-OB); (2) the Wilmington Harbor navigation channel to Wilmington, excluding the ocean bar and portions above the Lower Brunswick channel (WH-NAV); and (3) the MOTSU channel. Of the total material disposed in the ODMDS, approximately 1S.S Mcy (56%) of the material has come from WH-NAV and the MOTSU channels. Table 1.

Major Modification to CAMA Permit # 91-14 - March 2020 South Beach Renourishment Project Village of Bald Head Island, Brunswick County, North Carolina 10 As identified in Table 2, the mid -project reaches of WH-NAV and MOTSU exhibit significantly higher silt and clay components not compatible with beach placement. MOTSU dredged material alone (accounting for 12 Mcy or 43% of the total material placed in the ODMDS since 1987) is characterized as silty riverine sediments consisting of 70% silt and clay. Additionally, it is commonly reported that the ODMDS consists of woody debris associated with prior dredging of the river bottom. Since the development of the Sand Management Plan (as part of the Wilmington Harbor Deepening Project in 2000), beach compatible sand dredged during maintenance events has been pumped to the shorelines of Bald Head Island and Oak Island. As a result, much of the material disposal at the new ODMDS location consists of higher silt and clay content. In light of these documented conditions, use of either the old or the new ODMDS sites has been determined to be not practicable and has been eliminated from further consideration in the following analysis of potential actions.

The 1989 Environmental Impact Statement (EIS) for the long- term maintenance of Wilmington Harbor (USACE 1989) identified eighteen (18) disposal sites extending from Snow Marsh Channel (north of Southport) to near the upstream limit of the federal project on the Northeast Cape Fear River (just north of the mouth of Smith Creek) (refer to Attachment A). The disposal areas were originally formed from pumping material to unconfined areas along maintained channel reaches. Over time, the federal project included the construction of upland dikes to contain the dredged material. Most of these diked upland facilities have since been abandoned by the USACE. These areas range in size with all but one site (Area 15 on Eagles Island) less than 50 acres. Many of the sites have eroding dikes and have been subsequently overgrown by Phragmites australis and wetland plant species. Based upon the location of these areas, many of the sites consist of mixed material with higher content of fine-grained sediments. Only two sites (Area 3 and Area 4) are still maintained by the USACE as CDFs. Area 3 (29 ac) has mixed sediment content and would likely not be a suitable source candidate for beach quality material. Area 4 (25 ac) consists predominantly of beach -compatible sand. However, sand from this island is dedicated for the federally -authorized Kure Beach project in New Hanover County (NC). Based upon documentation of existing disposal areas of the Wilmington Harbor project, use of any single CDF as a source of beach -compatible sand is not viable. All but one of these sites consists of mixed sediment content deemed unsuitable for beach placement. The one CDF (Area 4) that contains higher percent sand content is dedicated as a sand source for the federally -authorized Kure Beach project. Given the quantity of sand required for nourishment on Bald Head Island, the State technical standards the material must meet, and issues associated with constructability, CDFs are not considered a practicable sand source alternative. Frying Pan Shoals (Applicant's Preferred Alternative) The screening and identification of a suitable borrow site considered the following conditions: • documented strata of high quality beach compatible sediment suitable for meeting both State Standards and post -placement performance criteria acceptable to the Engineer and the project Sponsor (and in quantities sufficient to nourish the entirety of South Beach), • desirable constructability characteristics for purposes of sand excavation and beach fill construction by an ocean -certified cutter suction dredge; • avoidance of cultural resources necessary for operational feasibility, and • siting of the borrow area in a known dynamic but highly depositional area for purposes of ensuring rapid substrate recovery; • siting of the borrow area to minimize biological impacts to resident and transient species and their habitats (including Essential Fish Habitat); and • reasonable accessibility to Bald Head Island and proximity to nourishment site for logistic and cost considerations (i.e. the project must be practicable and not prohibitively expensive). In light of the criteria identified to meet the Applicant's project purpose and need, use of a potential borrow site beyond three nautical miles (i.e. in federal waters) would not be feasible. In particular, such a site would not provide reasonable accessibility to the nourishment site (needed for operational benefits), would be cost prohibitive, and would necessitate working outside of acceptable environmental windows. In addition, it would require the use of a hopper dredge that would result in entrainment impacts to fish and sea turtles as well as increased risk of collision with protected cetaceans. As a result, Olsen Associates, Inc. (OAI) identified a nearshore Major Modification to CAMA Permit # 91-14 — March 2020 South Beach Renourishment Project Village of Bald Head Island, Brunswick County, North Carolina 12 candidate sand source (i.e. potential borrow area) on Frying Pan Shoals that is further described below as the Applicant's preferred alternative. In addition, more detailed information regarding existing conditions and proposed work is provided. ON has identified a preferred borrow site location (consisting of an evaluation area of approximately 460 acres) along the west side of Frying Pan Shoals approximately 1 mile seaward of the southeastern shoreline of Bald Head Island. Frying Pan Shoals is a submerged extension of a large-scale cuspate foreland (i.e. accretional feature formed by the historical deposition of a longshore drift originating from both the north and the west). The shoal formation extends well over thirty miles offshore from the eastern end of Bald Head Island. Prior federal studies have identified the presence of vast quantities of beach -quality sand throughout much of the shoal formation. The Village recently initiated more detailed site investigations (including hydrographic surveys, geotechnical investigations, and marine cultural resource surveys). Based upon these studies and subsequent engineering analysis, the identified borrow site has been further refined to an approximate 198.4-acre area (refer to Permit Sheet 7 of 9). Avoidance and minimization measures are further described in Section 3.1.6 below. 3.1.3 Existing Conditions Bald Head Island is a 3-mile long south -facing coastal barrier island located immediately eastward of the mouth of the Cape Fear River at 33.85°N, 77.9889°W (NAD27). The island forms the southern terminus of the Smith Island complex at Cape Fear Point from which the Frying Pan Shoal formation extends over thirty miles southeastward into the Atlantic Ocean. Bald Head Island's east and south shorelines (East Beach and South Beach, respectively) front Onslow Bay and the Atlantic Ocean, respectively. The western shoreline (a.k.a. West Beach) is located immediately adjacent to, and fronts, the Cape Fear River entrance. The north side of the island is bounded by the Bald Head Creek estuary. The remainder of Smith Island is composed of interior tidal creeks (including Cape Creek and Deep Creek), associated tidal marsh, Middle Island, and Bluff Island. The mouth of the Cape Fear River (over one mile in width) separates Bald Head Island from the eastern end of Oak Island (or Caswell Beach). As described above, Frying Pan Shoals is a submerged extension of a mega -scale cuspate foreland extending from the southeastern point of Bald Head Island and extending greater than 30 miles offshore. Prior evaluations conducted by the USACE as part of the General Reevaluation Report (GRR) for the Brunswick County Beaches Coastal Storm Damage Reduction Project indicated the presence of substantial volumes of "beach -compatible" material within Frying Pan Shoals. 3.1.4 Investigations As a prelude to a comprehensive Sand Search Investigation, (Olsen Associates, Inc. 2016), the firm's subconsultant Geodynamics performed a hydrographic survey of the area of interest along Frying Pan Shoals (since NOAA charts are both dated and highly inaccurate in that dynamic area). Similarly, Tidewater Atlantic Research, Inc. (TAR, 2016) performed two (2) phases of marine cultural resource investigation to discern the location of potential wrecks within the study area. The Phase II investigation identified one small buffer area mapped around one cluster of magnetic anomalies recommended to be avoided (TAR 2016). Accordingly, a 9.73-acre Exclusion Zone within the global 460.1-acre borrow area has been delineated — based upon the T.A.R. findings. Athena Technologies, Inc. was retained to obtain multiple vibracores throughout the proposed area of interest (where physically feasible). Those cores have been logged and analyzed for sand quality. OA subsequently formulated a summary report of the Sand Search Investigation (Olsen Associates, Inc. 2016). According to this report, the grand mean sand content for composite samples from the proposed borrow area was 92.09%, and the Major Modification to CAMA Permit # 91-14 — March 2020 South Beach Renourishment Project Village of Bald Head Island, Brunswick County, North Carolina 13 percent fines measured over depth (to -25 ft MLW) was low (2% on average). It can be reasonably expected based upon these results and the findings of other geotechnical investigations in similarly occurring, nearby shoal features that depositional sediments above a certain elevation within the defined borrow area are reliably of beach quality. Based upon experience with borrow site development and construction within Jay Bird Shoals, the continuity of the predicted horizon of sands above layers of either clay or silty sands is highly predictable at this location (Olsen Associates 2016). The permit request therefore seeks authorization to dredge above that horizon. 3.1.5 Proposed Work In order to plan for and address expected sediment deficits over the next several decades, the Village of Bald Head Island has identified an approximate 460.1-acre sand source for the acquisition of beach -compatible material suitable for placement along the South Beach shoreline. The volume of sand placed for such a renourishment project should be sufficient to both address expected sediment losses between federal disposal events, as well as ensure adequate improved beach widths along the entirety of the South Beach shorefront. A predicted Contract volume is estimated not to exceed 2.5 Mcy of beach fill (including losses experienced during dredging and fill placement). A maximum Phase 1 (198.4 acres) borrow site to be permitted is located on the western portion of the Frying Pan Shoals formation approximately 1 mile off the southeast shoreline of Bald Head Island within the 460.1-acre area discussed above. Sediment identified within the Frying Pan Shoals borrow site will be excavated by cutter suction dredge and pumped by submerged pipeline to the South Beach shoreline. Assuming a neat sand volume to a depth of -20 ft NAVD88, the identified borrow site could theoretically yield up to 2.487 Mcy. To an elevation of -25 ft NAVD88, the neat sand volume is estimated to be 3.995 Mcy. Within the requested 198.4-acre borrow site there is included a 9.73-acre Exclusion Zone intended to avoid impact to potential cultural resources as identified by T.A.R. Hence, the net area available for dredging is 188.7 acres. Pragmatically, it is expected that the Contractor's Dredge Plan submitted prior to construction could reduce the actual spatial acreage dredged by up to 25%. The South Beach construction fill template will maintain an approximate average berm elevation of +8 ft. NGVD which is consistent with prior beach fill berms constructed by the Wilmington District USACE and the Village since 2001. 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 duneline. As in the past, any revegetation necessary for dune stabilization will be performed by the Village under separate contract subsequent to fill placement completion by the dredge contractor. Post - construction beach tilling will be performed based upon consultation with Resource Agencies after each future fill event. To -date however, that requirement has been waived after an on -site evaluation by agency personnel. It can be reliably assumed that a 27"-30" cutter suction dredge (Ocean Certified) must be utilized to excavate material from the permitted open water site. Both draft and operational (as well as safety) considerations for such dredge plants necessitate depths of excavation exceeding -15 ft (MLLW datum). 3.1.6 Avoidance and Minimization Measures The selection of the proposed Phase I Bald Head Island 198.4-acre borrow site capitalized on the findings of hydrographic surveys, geotechnical investigations, and two phases of cultural resource investigation. Of specific interest in the development of the initial F.P.S. borrow site were the following desirable characteristics: • reasonable accessibility to Bald Head Island; • the availability of a Harbor of Refuge for the cutter -suction dredge during periods of inclement weather; Major Modification to CAMA Permit # 91-14 — March 2020 South Beach Renourishment Project Village of Bald Head Island, Brunswick County, North Carolina 14 • documented strata of high -quality beach compatible sediment suitable for meeting both State Standards and post -placement performance criteria acceptable to the Engineer and the project Sponsor; • desirable constructability characteristics for purposes of sand excavation and beach fill construction by an Ocean -Certified cutter suction dredge; • avoidance of cultural resources necessary for operational feasibility, and • siting of the borrow area in a known dynamic and highly depositional area for purposes of predictable rapid infilling — thereby ensuring both substrate and benthic recovery between dredge events. The specified design depth of the proposed borrow site will ensure that substrate sediments exposed immediately after project construction will continue to consist of high -quality sands. Borrow site "recovery" (i.e. infilling) will initially be influenced by both slumping of excavation perimeter side slopes and rapid deposition from predictable sediment transport from north to south along the marginal shoal feature — as presently exists today. Advance quantification of infilling rates is difficult due to equilibration processes between cut and uncut portions of shoal during the first few years following dredging. Consequently, physical monitoring of the borrow site recovery will be performed. It is well documented however that the section of shoal in question is naturally depositional both in the modern day and the morphological sense. Regardless of future realized sediment deposition rates, the probability of sedimentation by similar sandy material (in contrast to fines, organics, clays, etc.) is excellent (McNinch, 2009) and coincidently is the principal post -construction borrow site characteristic desired for purposes of rapid recovery of benthic communities (Bergquist, et.al. 2008) and corresponding minimization of potential adverse effects to Essential Fish Habitat (EFH). The project as designed will incorporate the following protection measures identified by the South Atlantic Fisheries Management Council (SAFMC) specific for dredge and fill projects in areas designated as Habitat Areas of Particular Concern (HAPC). These include the following: 1. Impact assessment (description of potential impacts; baseline information; alternatives analysis; construction monitoring; post -construction monitoring plan); 2. Fill material should match that of recipient beach as closely as possible; 3. Dredging to be located in areas characterized by strong currents and sand movement to promote more rapid infilling rates (and thus reducing the duration of impacts to benthic habitats); and 4. Dredging should be performed in a manner intended to minimize impacts to wave energy and currents, "thus reducing the likelihood of infilling with fine-grained sediments". In addition to the SAFMC protection measures, the proposed project incorporates following design elements that helps to further reduce or avoid impacts to natural resources: 1. The site is a highly dynamic and renewable shoal feature (maintained by seaward flow of current off cape) and thus physical and biological disturbances tend to be short-lived; 2. The position of borrow site on the western flank represents a sediment sink (thus promoting rapid recovery and infilling with like material); 3. The combination of size and position of sand source site results in least impacts to shoal integrity; 4. Dredging to occur during winter months (reduced biological activity); 5. The project will allow for undredged areas in close proximity to be left undisturbed to promote more rapid recolonization of benthos (as was documented for Jay Bird Shoals and Bald Head Creek Shoals with similar post -project conditions); 6. The project will avoid hard -bottom habitat; 7. The project will avoid Primary Nursery Area (PNA) impacts; Major Modification to CAMA Permit # 91-14 — March 2020 South Beach Renourishment Project Village of Bald Head Island, Brunswick County, North Carolina 15 8. The project will avoid inlet and associated shoals for large-scale sand volume needs'; 9. The project will utilize hydraulic cutter suction dredge (thereby avoiding and minimizing physical entrainment of species in close proximity to the dredge operation); 10. The project will include post -project physical monitoring of borrow site (i.e. assessment of physical recovery); and 11. Any revegetation necessary for dune stabilization at the nourishment site would be performed by the Village under separate contract subsequent to fill placement completion by the dredge contractor. 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); 5. Avoidance of shorebird and colonial waterbird nesting areas; and 6. Physical monitoring (see Section 3.1.7 below). 3.1.7 Post -Construction Monitoring The Village as Permittee shall perform physical monitoring of the dredged F.P.S. borrow site immediately after construction, annually for three (3) years and biennially thereafter. The post -construction bathymetry will be compared annually with subsequent monitoring results to calculate in -filling or "recharge" 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 area plus a 500-ft buffer outside the site. No changes in morphology to the Frying Pan Shoals formation is anticipated; however, changes in bathymetry throughout the study area as well as proximate to any cultural resource buffer will be monitored. At present, based upon the continuation of federal beach disposal events at South Beach in accordance with the Wilmington Harbor Sand Management Plan, it is predicted that the Village would potentially be required to episodically borrow sand from Frying Pan Shoals every 9 to 10 years. The Village will recoordinate with all State and Federal regulatory agencies prior to the initiation of any proposed redundant excavation within the overall permitted area. The strategic design rationale for each future excavation will be provided for all subsequent dredging operations or contracts proposed by the Village. The frequency of physical monitoring surveys will be "reset" after any future dredging event. 2 All coastal inlets are designated HAPC for paneaid shrimp, blue crabs, and estuarine -dependent snapper -grouper species.
