Correspondingly, the oceanfront of Figure Eight Island has suffered an accelerated rate of erosion, depleting material on the open beach and seriously eroding the primary dunes on the upper beach in this area. The proposed project is for the maintenance of the navigation channel and the rebuilding of the ocean beaches on the southern portion of Figure Eight Island. The area to be dredged is the same area previously dredged in prior projects with the possible exception of a portion of the channel that connects Banks Channel to the Atlantic Intracoastal Waterway ("Waterway Connector Channel"). There is no known documentation of whether this connector channel has been dredged, but it has been I continuously used for navigation since Figure Eight was developed beginning in the mid-to-late 1960s. The channel existed as a natural channel prior to the 1960s and its use by fishermen, hunters and other recreational users prior to the development of Figure Eight is known to older residents of the area. This navigation channel currently serves as the only viable connector to the Intracoastal Waterway for 197 sound side property owners. An 800' section of the connector channel beginning at the AIWW has been previously dredged. The remaining portion of the waterway connector is approximately 2,900'. The history of permits for the navigation channel is set forth in Attachment B to Form MP-1. The history discloses that much of the navigation channel was dredged during the original development in 1969 with a 300' authorized width and a -18' authorized depth. A small project by consortium of homeowners was implemented in 1985 primarily for the purpose of obtaining sand for an experimental beach protection project. The original 1992 permit authorized the dredging of a 125' x 5,500' channel behind the southern end of Figure Eight with the southern extent of dredging extending to the 1992 location of Mason Inlet. The 1992 project was twice modified. The first modification added the entrances to the two lagoons. The second modification ' extended the project northward to cover all of Banks Channel as well as an 800' long area where the waterway connector meets the AIWW. In 1992 Mason Inlet was located slightly farther south than its current location. The permit apparently allowed connection of the southern end of the channel to the throat of Mason Inlet, but the actual dredging stopped a few hundred feet north due to lack of funds and contractual commitments. 5272 - 4.13.04 Pagel 1I t The 1998 permit allowed dredging in the same location and to the same dimensions as the modified 1992 permit with the exception that the dredging was terminated 200' south of the southern lagoon rather than extending southward to the 1992 location of Mason Inlet. The 1998 permit also allowed wider and deeper connections between the two lagoons and Banks Channel. Figure Eight did the work authorized in the '98 permit but dredged only -6' MLW due to an agreement with Shell Island Resort. All of the prior projects resulted in disposal of the dredged sand on the ocean beaches of Figure Eight south of the causeway. The 1969 permit may have also resulted in disposal of sand on upland areas other than the active ocean beach. Project Description ' Maintenance dredging is in the sub-tidal shoal areas in the proposed generally open water area of Banks Channel and the Waterway Connector Channel. There are one or two small areas where the shoal areas may be intertidal. Banks Channel and the Waterway Connector Channel are the primary navigation channels as well as the main hydraulic channels for the sound area behind Figure Eight. These channels have been relatively stable through the years but hurricane activity mentioned before, which had high water beach overwash along with storm-level erosion, created some ' redistribution of shore and bottom sediments. Also the long term instability of Mason Inlet as it migrated southward contributed to a higher level of sediments to the navigation channels. In 2002 the Inlet Relocation Project created another unstable condition at the inlet and its sediment basins and resulted in more sediments being fed into the navigation channel. The creeks connecting to Banks Channel have been choked in some locations due to this higher level of sedimentation. This project will offer the additional benefit of restoring flows so as to allow natural processes to rechannel these creek mouths. All of the sand materials removed will be discharged along approximately 10,000 linear feet of beachfront, extending from the southernmost lots northward. A transition adapted to the existing beach profile approximately 300 to 400 feet long will be provided at both ends of the beach fill. The basic dimensions of the beach fill will be to an elevation of approximately 9.5' mean sea level (MSL) with a berm width of at least 100'. The ocean side of the berm will be shaped to an approximately 20:1 slope between elevation 7 and -2.0' MSL (see sheets 1 and 3 of the permit application for sketches of beach fill location and proposed beach profile). It is estimated that approximately 230,000 cubic yards of medium to fine sand materials will be excavated from the proposed area to be dredged by hydraulic pipeline dredge. The material will be transported by the dredge pipeline and deposited along the beachfront using a temporary protective berm parallel to the shoreline to control the effluent run-off, ensuring maximum upland beach deposition of the material and minimizing turbidities within the surf zone. 1 5272 - 4.13.04 Page 2 I' Test borings and sand samples were taken during March 2004 along the length of the proposed channel maintenance dredging areas and on the ocean beach as shown on the sample location map of the attached report (Appendix 6a). The sampling and testing were done by an independent geotechnical contractor with one sample extracted from the near-bottom area and a second sample at -9 MLW. A grain size analysis of the materials sampled is attached hereto. Current visual ob- servation of the areas to be dredged and visual observation of the material dredged in 1999 indi- cate that the current sediments are essentially the same as those dredged in 1993 and 1999. All excavations are to be done by hydraulic pipeline dredge. All materials excavated will be pumped to selected beach locations to reconstruct the beach sections as described above. Pipe- line corridors will be established to ensure that no marsh areas or sensitive vegetation will be crossed during the operation. All dredging will be done during the winter season when biological activities in both the sound and beach areas will be at a minimum.

Channel bottom areas that will be disturbed during dredging operations have either been previously dredged during the original island development and channel maintenance operations or used continuously for navigation purposes. The run of ' Banks Channel north and west to the Intracoastal Waterway represents the primary means of access to regional fishing areas and navigable ocean inlets for boat owners on the southern half of Figure Eight Island. Banks Channel is also a protected area for water skiing. Waterway Connection Along with the dredging of the main run of Banks Channel, CAMA Permit 29-98 also authorized an 800' long dredging area from the Intracoastal Waterway into the northwest end of the connector to Banks Channel. The current proposal includes this 800' segment with a 450' extension to the east to cover an area currently shoaled to less than -5' mlw. This is the most shallow channel area between the waterway and Banks Channel and currently impacts navigation for larger boats. The applicant is currently coordinating with NCDMF to perform a shellfish survey within the 450' extension to determine the presence and abundance of any resource. Navigation/Shoaling In 2002, New Hanover County moved Mason inlet approximately 3000' north of its former location. Since that time, the inshore areas have experienced significant sand deposition with the formation of the flood shoal system. Currently, extensive shoal areas exist from roughly the location of the entrance to the southern lagoon southward for a distance of over 2000' to the inlet and entrance to Mason Creek. The proposed excavation area for this portion of the project has been designed to minimize impacts to intertidal shoals by generally aligning with the 0' mlw contour at the southern extent as shown on sheet C7. Excavation will not extend beyond 200' south of the southern lagoon entrance. Navigation from Banks Channel to the south to reach either the ocean through Mason Inlet or the waterway through Mason Creek will continue to be unreliable and potentially hazardous. The applicant understands that New Hanover County will be moving forward with seeking authorization for the first maintenance event for the Mason Inlet Relocation Project. While that is a separate, distinct project with a different purpose, the applicant is willing to coordinate with the County in an attempt to utilize the same dredging contractor to perform both projects under a single mobilization effort, provided that both projects are authorized for the same dredging season. This coordination has the potential to minimize overall disturbance. 1 5272 APPENDIX A-4.14.04 I Laeoons and Canals The lagoons and canal system originally formed during island development are proposed to be maintained as part of the project. At present, the lagoon entrances are impacted by subtidal shoaling, which inhibits tidal circulation and could impact the levels of dissolved oxygen within ' the lagoons. Clearing shoals from the lagoon mouths will provide optimal flushing and navigation safety. ' Beach Disposal Much of the area to be dredged consists of deposited sand set into motion by hurricane activity and the relocation of Mason Inlet. The origin of most of the material to be dredged from Banks ' Channel is the ocean beach itself. Through littoral drift, flood shoal formation processes and storm effects, the sand has accumulated most noticeably within the southern quarter of the proposed dredging area. Soil samples were taken in March, 2004 to determine the relative soil ' characteristics of the beach and sound area. Beach samples tested similar to those taken in 1992 with that near the southern end slightly finer (in gradation) than that from the center of the beach segment. Samples taken in Banks Channel show a slightly smaller median grain size than that from the beach strand. This can be explained as a normal indication of the smaller particles becoming water-borne and carried inside the inlet to form alluvial deposits. Grain sizes within the interior lagoons and canals are also smaller than beach sands. It is felt however that a portion of these smaller particles will serve to infill the larger voids within the sand on the beach while the remaining suspended particles will settle fairly rapidly in down-drift areas. Should pockets of extremely fine sediments be encountered, these materials will be compartmentalized within a ' temporary diked area on the upper dry sand beach, allowed to dewater and then mixed mechanically by dozers before final grading. The removal of these deposits from the lagoons and canals will ultimately allow better water circulation and flushing as well as restore original navigation safety. The environmental impacts resulting from the disposal of the dredged material on the beach should be similar to or less than those of authorized past nourishment projects on Figure Eight Island or Wrightsville Beach. The deposition of material on the beach will occur i' between November 15th and March 31St in order to avoid impacts to turtle nesting and migration. No hopper dredges that have the capability to entrain turtles will be utilized during the project. As with similar former projects here, there is no reason to believe the sediments to be excavated and deposited on the beach have been exposed to any environmental contamination event. In order to minimize the amount of turbidity and suspended sediments in the surf zone, a diversion berm formed parallel to the shoreline and generally centered on the 0.0 MSL contour will prevent the sand and water mixture pumped to the beach from flowing directly into the surf. The 200'+ berm maintained in advance of the discharge pipe, will allow the maximum amount of particulate settling before allowing the water to return to the ocean. Following mechanical ' shaping of the upper dry sand beach in the disposal area and after the actions of several tidal cycles, the resulting beach profile is anticipated to slope at 15 to 20:1 above MHW and 20 to ' 30:1 below MHW out to just beyond the MLLW contour. The beach will be monitored the April following the project to remove any escarpment that may present an impediment to turtle nesting. 5272 APPENDIX A-4.14.04 2 1I 1I Coastal Wetlands/PNA's/SAV's No areas of vegetated coastal wetlands are to be disturbed by the proposed project. The planned channel dredging will occur far enough offshore of marsh areas so as to allow for an equilibrated side slope of 3:1 to form without threatening stands of vegetation. The channel excavation work will not be performed within any Primary Nursery Area (PNA) as designated by the NC Division of Marine Fisheries. No areas of submerged aquatic vegetation (SAV's) are known to exist south of Pender County. The dredge pipeline will be oriented to cross the shoreline in areas that do not have a coastal wetland fringe or 404 wetlands. Essential Fish Habitat (EFH) Essential Fish Habitat (EFH) provisions of the Magnuson-Stevens Fishery Conservation and Management Act help to maintain marine fishery habitat quality and quantity through National Marine Fisheries Service (NMFS) and regional fishery management council consultation on proposed projects that may affect fishery managed species either directly or indirectly. The proposed area of maintenance dredging and associated beachfront disposal is located in an area identified as EFH for postlarval, juvenile, and adult red drum (Sciaenops ocellatus), bluefish (Pomatomus saltatrix), summer flounder (Paralichthys dentatus), cobia (Rachycentron canadum), brown shrimp (Penaeus aziecus), pink shrimp (Farfantepeneaus duorarum), and white shrimp (Farfantepeneaus setiferus). Juvenile and adult gag grouper (Nycteroperca microlepsis), gray snapper (Lutjanus griseus), king mackerel (Scomberomorus cavalla), spanish mackerel (Scomberomorus maculatus) may also utilize EFH of the area. Table 1 provides a list of all EFH species (including life history stage) present in Middle Sound and Mason Inlet. Other estuarine-dependent species including spot (Leiostomus xanthurus), Atlantic menhaden (Brevoortia tyrannus), and striped mullet (Mugil cephalus) that serve as prey for fisheries managed species (e.g. snappers, groupers, tuna, and sharks) inhabit the Middle Sound complex. Categories of EFH within and adjacent to the project area include estuarine emergent wetlands, intertidal/subtidal bottom habitats, oyster/shellfish beds, and estuarine/marine water column. The Fishery Management Plan Amendments of the South Atlantic Fishery Management Council (FMC) have targeted specific categories of EFH and Habitat of Particular Concern (HAPC) as depicted in Table 2. Table 3 provides an impact summary for all designated categories of EFH and HAPC. While all twenty-six (26) habitat categories occur in waters of the southeastern United States, only those existing within or adjacent to the project area are addressed in this evaluation. ' Impacts on Estuarine Emergent Wetlands As discussed above, there will be no impacts disposal activities. The dredge corridor within ' located sufficiently waterward of existing marsh without any disturbance to marsh vegetation. 5272 APPENDIX A-4.14.04 X11 to emergent wetlands from either dredge or Banks Channel and connecting waters will be to allow for an equilibrated side-slope of 3:1 Impacts on Intertidal Flats (includine sand and mud bottom habitats) Intertidal flats and subtidal bottom will be directly impacted by the removal of sediment accumulating within Banks Channel and connecting waters. Nearly the entire length of the proposed dredge corridor, however, has been dredged under previous CAMA permit ' authorizations. The only area not previously permitted for dredging is the 450-ft extension located near the Intracoastal Waterway (as discussed above). The entire project area represents an area traditionally maintained for recreational boat use and navigation. Based upon recent detailed hydrographic surveys of the area, much of the proposed dredge corridor is located over subtidal bottom habitat. Of the approximately 57.1 ac to be dredged, 1.3 ac consists of intertidal sand flats. The excavation of these intertidal areas will result in the conversion of intertidal sand flat to subtidal bottom (average design depth of - 9 ft MLW). Fish species (particularly summer flounder) utilizing this type of habitat as resting areas during migration to and from back-barrier marsh complexes will be displaced to adjacent intertidal sand flats. Typically, larval and post-larval summer flounder drift and migrate inshore during the late winter, while sub-adults migrate offshore during the late summer and fall. Though temporary disturbance/displacement may occur, this area of intertidal flats is relatively small in proportion to the expanse of unvegetated intertidal habitat located adjacent to the project area. ' Benthic prey items of fish populations utilizing intertidal flats will be subject to abrupt impact from dredging and nourishment activities. However, Reilly and Bellis (1978) reported that population regeneration occurs within 1 to 2 seasons once pumping operation ceases. Essink et ' al. (1998) reported that species densities, biomass, and diversity of the zoobenthic community of beachfront habitats returned to pre-project values within one to two years . Other studies (National Research Council, 1995; Hackney et al., 1996; Ross and Lancaster, 1996) suggest that species recovery will occur rather quickly provided certain mitigative measures (i.e. avoiding peak recruitment periods) are employed. Project activities will result in direct disturbance to estuarine, subtidal and intertidal habitat. These habitat types are continually subject to natural dynamic forces (e.g. waves, wind, and storm events) that drive depositional processes. As a result, species utilizing this habitat are continually adapting to changes in substrate elevation and surface area. In addition, the dredge corridor represents an area historically maintained and dredged. Processes contributing to the formation of intertidal habitat outside the project area will not be affected. The expanse of intertidal flats beyond the project area will continue to be utilized by the listed fish species. Therefore, the cumulative effect of maintenance dredging and nourishment to intertidal flat EFH is not considered to be significant. Oyster Reefs and Shellfish Beds Intertidal oyster reefs and subtidal oyster beds provide important ecosystem functions including structural complexity for refuge, water column filtering, and feed habitat for resident and transient species (Coen et al. 1999). Marine invertebrate species such as polychaetes, crabs, and amphipods that reside within oyster reef communities serve as important prey items for red I1 5272 APPENDIX A-4.14.04 4 drum, summer flounder, striped bass, and other finfish species (Noble 1999). As such, oyster reefs have been designated as EFH by the South Atlantic Fishery Management Council. No oyster reefs are located within the project area. Scattered oyster beds are located along interior creeks of Middle Sound with some occurring near marsh edges of open water. However, the area of the proposed dredge corridor will be located a sufficient distance from marsh edges as to avoid disturbance to any potential oyster beds. In addition, the applicant has coordinated with the NC Division of Marine Fisheries (DMF) to identify the presence of potential shellfish resources in the project area. Available shellfish survey data from DMF indicate that no oyster or clam resources were present from sampling within the mapped habitat type to be impacted by the project. Therefore, it is unlikely that the proposed activities will impact this category of EFH. Impacts on the Marine and Estuarine Water Column Mortality of organisms lacking the ability to escape the suction field of an operating dredge and subsequent entrainment in the flow of water and sediment passing through its pumping equipment is likely. However, previous USACE studies have demonstrated that only an ' extremely small percentage (a fraction of 1%) of marine and estuarine larvae are subject to entrainment based upon the amount of water that a dredge can pump. Dredge entrainment impacts to bottom-dwelling fish, crabs and free-swimming larval organisms is anticipated to approximate those of other authorized navigation projects. No significant impact on these life forms is expected at local or regional population levels. I' During beach deposition, immediate localized impact from abrupt increases in sedimentation along the surf zone may negatively affect fish present at the time of the proposed work. However, siltation and turbidity within the surf zone will be minimized through the use of a ' diversion berm (see description above). Placement of sediment consisting predominantly of medium to fine grain size sands will minimize turbidity and/or other water quality impacts. ' According to USACE (1997), sediment consisting of more than 90% sand is not likely to produce significant turbidity. These design elements will minimize water quality impacts and subsequent disturbance to estuarine-dependent and surf zone fishes. Effects of any elevated turbidity will be limited both temporally and spatially. Turbidity levels tend to decrease rapidly subsequent to dredging or excavation through simple mixing and dilution processes (associated with tidal currents and wind). Indeed storm events can produce equally hi levels of II' suspended sediments. The spatial scale of elevated turbidity related to dredging is often minor (USACE 2001). ' No quantitative assessments have been conducted to evaluate beach nourishment impacts to surf zone fishes in this area. It is understood that federal agencies are currently discussing an integrated monitoring plan to gather data with which to identify more accurately potential impacts to fishes utilizing the immediate shoreline area. NMFS has commented that restricted lateral movement of early life stage fishes may make these individuals more susceptible to nourishment impacts. More mobile sub-adult and adults that prey upon benthic macrofauna of ' the surf zone (e.g. mole crabs and coquina clams) would likely move to adjacent undisturbed beach areas and other suitable feeding areas for the temporary period of benthic population re- ' 5272 APPENDIX A-4.14.04 5 11 establishment. It should be noted that the beach disposal area to be used is located entirely within the footprint previously permitted for the Mason Net Relocation Project. Impact Summary for Essential Fish Habitat Of the twenty-six (26) categories of identified EFH within southeastern United States, four categories (estuarine emergent wetlands, estuarine water column, marine water column, and intertidal/subtidal bottom) occur within or adjacent to the project area (refer to Table 3). Negative impacts associated with dredging and nourishment activities will be relatively short- term and confined predominantly to the three- to four-month project window. The project site has been historically dredged and maintained for recreational boat use. There will be no disturbance to estuarine emergent wetlands. The cumulative impact to fish habitat resulting from the proposed activities is considered to be minor and short-lived. Therefore, negative impacts to EFH associated with dredging of Banks Channel and connecting waters and the disposal of material on the beachfront of Figure Eight Island have been determined to be not significant. 5272 APPENDIX A-4.14.04 6 Table 1.

Project No. 22.10835 Engineering Consulting Services, Ltd. (ECS) has completed the subsurface exploration and laboratory testing for southern Figure Eight Island and Banks Channel in Wilmington, North Carolina. ECS obtained soil samples from twenty selected locations in the sound side channel and in four selected test locations on the beach. The channel locations were denoted as S-1 through S-20. The beach locations were denoted as B-1 through B-4. The channel soil samples were obtained at the bottom of the channel at the selected locations and at an approximate depth of nine feet below the mean low water level. The beach samples were obtained at the surface at the mid-tide level of the beach. This report presents the results of our laboratory tests, We appreciate the opportunity to provide laboratory services to you on this project.

Project No.: 22.10835 1.0 PROJECT OVERVIEW 1.1 Project Description and Scope of Work This report presents the results of our field soil sampling and laboratory tests for the Figure Eight Island located in Wilmington, North Carolina. The Project Location Diagram in the Appendix A shows the location of the site and the approximate location of the soil samples obtained. Our exploration consisted of obtaining soil samples in the channel and on the beach at twenty four selected locations. The sample locations were selected by Criser and Troutman Consulting Engineers. The soil samples from the channel were obtained at the bottom of the channel and at a depth approximately nine feet below mean low water. The soil samples from the beach were obtained at the surface at the mid-tide level of the beach. In conjunction with the field sampling, laboratory testing was performed to characterize the soil samples obtained from the sampling operations. The purpose of this investigation is to visually classify the soil samples and to perform grain size analysis for each sample. 2.0 FIELD EXPLORATION 2.1 Exploration Procedures 2.1.1 Field Testing The soil samples were obtained using a barge mounted rotary drilling rig, which utilized various cutting bits to advance the boreholes to collect the samples at the designated depths. 3.0 EXPLORATION RESULTS 3.1 Site Conditions The channel is on the sound side of Figure Eight Island and south of the bridge from the mainland. 3.2 Soil Conditions and Description During our investigation at the twenty four selected locations, we encountered typical native soils in each of the samples at this site. The subsurface soils consisted of silty sands, sandy silts, and clean sands. The depths tested vary from location to location due to the natural contours of the bottom of the channel and due to changes in the tide height that occurred during sampling operations. Based on site conditions, we were able to obtain 30 samples from the channel locations instead of the requested 40 samples. The sample depths were adjusted to account for variations in the tide level during sampling operations. Report of Field and Laboratory Testing Figure Eight Island Wilmington, North Carolina ECS, Ltd. Project No.: 22.10835 4.0 LABORATORY TESTING 4.1 Laboratory Testing Program ¦ The laboratory testing program consisted of performing moisture content tests and grain size analysis on the soil samples. All data obtained from the laboratory tests are included in Appendix ' B and Appendix C of this report. The soil samples collected for this investigation will be retained at our laboratory for a period of ' sixty (60) days, after which they will be discarded unless other instructions are received as to their disposition. 4.2 Visual Classification 7 An experienced soil engineer classified each soil sample collected based on the texture and plasticity in accordance with the Unified Soil Classification System. A brief explanation of the USCS is included with this report and provided on the grain size graphs. 4.3 Laboratory Testing Methods 4.3.1 Grain Size Analysis Tests The sieve analysis is performed by placing a dry soil sample, of known weight in a series of sieves which is moved in a lateral and vertical motion accompanied by jarring to keep the sample continuously moving over the sieves. The amount of soil retained on each sieve is recorded and plotted on a graph with the weight retained on a given sieve on the y-axis, and the sieve opening on the x-axis. The following sieves were used, as requested by Criser and Troutman, to determine the distribution of particle sizes of the soil samples: #4, #10, #20, #40, #60, #100, #140, and # 200.

Fullwood, Executive Director MEMORANDUM TO: Doug Huggett Division of Coastal Management FROM: Shannon Deaton, Program Manager Habitat Conservation Program DATE: July 15, 2004 SUBJECT: CAMA/Dredge & Fill Permit Application for Figure 8 Island HOA, Inc., Banks Channel and southern lagoons maintenance dredging with application of material to the southern ocean beach of Figure 8 Island, New Hanover County, North Carolina. The North Carolina Wildlife Resources Commission has reviewed the project for impacts to wildlife and fishery resources. Our comments are provided in accordance with provisions of the Fish and Wildlife Coordination Act (48 Stat. 401, as amended; 16 U.S.C. 661 et seq.) and the Coastal Area Management Act (G.S. 113A-100 through I I3A-128). The applicants propose to maintenance dredge previously authorized areas in Banks Channel and the southern Figure 8 lagoons to improve navigation. Also proposed is new dredging of a connector channel to the AIWW. All sediments would be pumped to the island's southern beach for renourishment. Work would occur between November 15 and March 31 to avoid peak biological activity, including the sea turtle nesting season. Waters to be dredged are classified SA - Outstanding Resource Waters and open to shellfish harvest. The ocean is classified SB. A total of 56.96 acres would be dredged, including direct impacts to 1.3 acres of intertidal sand flats. Direct impacts to this important waterbird resting and foraging habitat appear to have been reduced by limiting dredging to the deeper east side of Banks Channel. There is some question as to whether sediments to be pumped to the ocean beach are beach compatible. Sediments from the lagoons are finer than ocean beach sand and mechanical mixing (using bulldozers) is proposed if "extremely fine sediments" (Appendix 5A) are encountered.

Dredging 2 07/19/04 incompatible material on the beach may increase recovery time of beach invertebrate populations, thus affecting the quality and quantity of available forage for waterbirds and surf zone fishes. Quality of sea turtle nesting habitat could also be affected. Our greatest concern, however, involves the secondary interrelated and likely causal hydrologic and geologic relationships between Banks Channel dredging, Masons Creek shoaling, and Masons Inlet migration. In our review of the Masons Inlet Relocation Environmental Assessment in which Masons Creek was to be dredged, we anticipated that accelerated shoaling of Banks Channel would result. Sure enough, now that Masons Creek has been dredged and Masons Inlet relocated, we are presented with this project due to "deposited sand set into motion by hurricane activity and the relocation of Masons Inlet" (Appendix 5A). In our opinion, it is becoming increasing clear that the dredging of Banks Channel and the relocation of Masons Inlet are inextricably linked and that activities in one sub-site affect the hydrology, geology, and habitats of the other. Although the applicants' desires to separate projects and permits are understandable, failure to adequately assess this project's impacts on the Masons Inlet Relocation project to us makes this an incomplete application. Based on these concerns, we recommend the following project modifications. 1. If incompatible material (based on grain size and color) is used on the ocean beach, mixed or not, the project will include monitoring of beach invertebrate populations. Pre- and post-project comparisons of these populations as well as comparisons to other nearby beach nourishment projects should be made and reported to the review agencies. 2. A quantitative assessment of hydrologic and geologic changes resulting from the Banks Channel project in com6ination with Masons Inlet maintenance activities will be made to provide a complete estimate of changes in intertidal habitat area. Losses of intertidal habitat should be mitigated. Also, we suggest that past bird monitoring along Banks Channel associated with either the Masons Inlet Relocation or Figure Eight Island be reported and discussed in relation to intertidal habitat loss. 3. Due to the interconnectedness of Banks Channel dredging to relocation and maintenance of Masons Inlet, a publicly funded effort, and the overall scope of the project, an environmental assessment (EA) will be prepared. The CAMA dredge and fill permit application should be held in abeyance until the EA has been circulated for review. Thank you for the opportunity to comment on this application. If you have questions, please call Bennett Wynne at (252) 522-9736.

Recipients of this notice are encouraged to furnish comments on factors of concern represented by the above agencies directly to the respective agency, with a copy furnished to the Corps of Engineers. This notice initiates the Essential Fish Habitat (EFH) consultation requirements of the Magnuson-Stevens Fishery Conservation and Management Act. The District Engineer's initial determination is that the proposed project would not adversely impact EFH or associated fisheries managed by the South Atlantic or Mid Atlantic Fishery Management Councils or the National Marine Fisheries Service. This application is being considered pursuant to Section 404 of the Clean Water Act and Section 10 of the Rivers and Harbor Act of 1899 (33 U.S.C. 403). Any person may request, in writing within the comment period specified in the notice, that a public hearing be held to consider this application. Requests for public hearing shall state, with particularity, the reasons for holding a public hearing. The District Engineer has consulted the latest published version of the National Register of Historic Places for the presence or absence of registered properties, or properties listed as being eligible for inclusion therein, and this site is not registered property or property listed as being eligible for inclusion in the Register. Consultation of the National Register is the extent of cultural resource investigations by the District Engineer, and he is otherwise unaware of the presence of such resources. Presently, unknown archeological, scientific, prehistorical, or historical data may be lost or destroyed by work under the requested permit. The District Engineer, based on available information, is not aware that the proposed activity will affect species, or their critical habitat, designated as endangered or threatened pursuant to the Endangered Species Act of 1973. The decision, whether to issue a permit, will be based on an evaluation of the probable impacts, including cumulative impacts, of the proposed activity and its intended use on the public interest. Evaluation of the probable impacts that the proposed activity may have on the public interest requires a careful weighing of all those factors that become relevant in each particular case. The benefits that may be expected to accrue from the proposal must be balanced against its foreseeable detriments. The decision whether to authorize a proposal, and if so the conditions under which it will be allowed to occur, are therefore decided by the outcome of the general balancing process. 2 That decision should reflect the national concern for both protection and use of important resources. All factors that may be relevant to the proposal must be considered including the cumulative effects of it. Among those are conservation, economics, aesthetics, general environmental concerns, wetlands, cultural values, fish and wildlife values, flood hazards and flood plain values (according to Executive Order 11988), land use, navigation, shore erosion and accretion, recreation, water supply and conservation, water quality, energy needs, safety, food and fiber production, mineral needs, considerations of property ownership, and, in general, the needs and welfare of the people. For activities involving the placement of dredged or fill materials in waters of the United States, a permit will be denied if the discharge that would be authorized would not comply with the Environmental Protection Agency's 404(b)(1) guidelines. Subject to the preceding sentence and any other applicable guidelines or criteria, a permit will be granted unless the District Engineer decides that it would be contrary to the public interest. The Corps of Engineers is soliciting comments from the public; Federal, State and local agencies and officials; Indian Tribes and other interested parties to consider and evaluate the impacts of this proposed activity. Any comments received will be considered by the Corps of Engineers to decide whether to issue, modify, condition or deny a permit for this proposal. To make this decision, comments are used to assess impacts on endangered species, historic properties, water quality, general environmental effects and the other public interest factors listed above. Comments are used in the preparation of an Environmental Assessment (EA) and/or an Environmental Impact Statement (EIS) pursuant to the National Environmental Policy Act (NEPA). Comments are also used to decide the need for a public hearing and to decide the public interest of the proposed activity. Written comments pertinent to the proposed work, as outlined above, will be received in this office, Attention: Mr. Henry Wicker, until 4:15 p.m. September 23, 2004, or telephone (910) 251-4930.

PROJECT DESCRIPTION Figure 8 Island is a private residential barrier island located in the northeast corner of New Hanover County, adjacent to the Atlantic Ocean and Middle Sound, between Mason and Rich Inlets. The island is accessed - °from=the mainl'arrd at-the end of Edgewater Iub Road (SR-1402), by-a priat bridge a e _tlie ?L11anti .Intracoastal. Waterivay (AIWW'and an earthen--eau e ra which tray ersesMiddl S6&i& In the project area, the NC Division`of Wafer Quality cIassi$es the waters of the Atlantic ocean as-Sg: Tfie and the as SA-ORWZ and they _ - J Waferway are designated as Primary in the area of the proposed maintenance dredging, the open water areas of Banks Channel, the finger canals and the waterway connection channel are not designated as PNAs. Over the years, the Figure 8 Beach Homeowners Association have obtained a number of State permits for channel maintenance, beach renourishment, and beach bulldozing. In-1989, the Association initiated the development of a long range plan that addressed channel maintenance and beach restoration on an island- wide basis. The resulting State permits, #26-92 and #21-93, authorized channel maintenance projects at the north and south ends of the island, both with beach deposition of excavated materials. This beach reconstruction project was completed in 1993. The hurricanes of the mid to late 1990's caused extensive damage and created serious erosion of the beach on Figure 8 Island. In March 1998, the applicants were issued State Permit #29-98 authorizing the maintenance dredging of Banks Channel; with beach disposal of the excavated material (previously State Permit #26-92). Subsequently, in 1999, the applicants received State Permit # 12-99 to excavate an existing USACOE spoil disposal island adjacent to the AIWW, and pump the material to the beach at the middle of Figure 8 Island. In 2001, Permit #6-01 was issued to the applicants to dredge a portion of Nixon Channel and renourish the beach at the north end of Figure 8 Island (previously State Permit #21-93). In addition to their own permits, the beach on the southern end of Figure 8 Island was a permitted disposal area for a portion of the beach compatible sands generated from New Hanover County's Mason Inlet Relocation Project (State Permit # 151-01). That renourishment activity was completed in 2002, however, future maintenance dredging associated with that project may again propose to utilize the south end of Figure 8 Island as a disposal area for beach compatible spoils material. The current application proposes to re-establish safe navigation by completing maintenance dredging of the previously authorized channels (State Permits #26-92 & #29-98) and add the four existing (4) canal/lagoons to the area to be maintained. The lagoon and canal systems were originally constructed during the early development of the island and have not needed large-scale maintenance dredging in the past. In fact, except for the shoaling of the entrances to the lagoons (Sounds Point and Salt Meadow), very little dredging is proposed in the lagoon/canal areas. The applicant has included them with this application in an effort to present a comprehensive picture of the island's present and future maintenance dredging needs to be able to maintain existing navigational corridors around the island. All of the excavated material would be used for beach renourishment. The applicant has completed a series of test borings in the proposed dredge area and submitted grain size analysis data of the test results. Grain sizes of the sediments in the canal/lagoon systems were smaller than the beach sands. The applicant proposes that if significant pockets of extremely fine sediments are encountered, they can be compartmentalized in a temporary dike on the upper dry sand beach, dewatered and mechanically mixed by dozers prior to final grading. Figure 8 Homeowners Assoc., Inc. Page 3 The proposed project-includes the following areas: M - 1. Banks Channel - 7,750' X 125' X -9' MLW. 2. Waterway Connector Channel - 1,850'. X 125' X -9' MLW: This includes the 600 L_F section connected to Banks Channel, the 800 LF section previously permitted at the channel's connection to the AIWW, and a proposed 450 LF extension on the east end of - - - :- -the waterway c-onneetion channel.:::.- - 3, "Backfin/Causeway Canal _ 2,450'-X-:1 25' X -9' MLW - _= 4::: Sand PQit t banal 2 2ftX 125". 9'-!'AL =- _ 5.

The south end of the project would terminate approximately 200 feet south of the southern-most lagoon (Sounds Point), as authorized in the 1998 permit (#29-98). The excavated sand sediments would be pumped to the southern end of the Figure 8 Island oceanfront (up to 10,000 LF) to be utilized in beach renourishment and reconstruction. The resulting beach profile is anticipated to be a continuous berm, constructed to approximately 9.5 feet elevation, with a minimum width of 100 feet, tapering toward the ocean at an approximate 20:1 slope. It is estimated that approximately 230,000 cubic yards of medium to fine grain sandy material would be generated from the proposed maintenance excavation. 9. ANTICIPATED IMPACTS The project would result in the excavation of 2,481,250 square feet (56.96 acres) of subtidal, shallow bottom within the combined project areas of Banks Channel, the waterway connector channel, and the canal/lagoon system. Approximately 56,628 square feet (1.3 acres) of that total would be inter-tidal sand' flats. The only area not previously authorized for excavation is the proposed extension of the waterway connection channel (450' X 125' X -9' MLW). The projected 230,000 cubic yards of dredged sand sediments would be placed on the southern end of Figure 8 Island's upper beach shoreline (10,000' X ±200'). The dredging and beach renourishment activities would create short-term turbidity, as well as, impact the intertidal macro fauna and benthic communities within the proposed excavation and spoil disposal areas. The applicant contends that adverse impacts would be minimized by timing the project to avoid periods of peak biological activity and outside of sea turtle nesting season, and that affected species populations would return to pre-project distributions within one or two years. The applicant's consultants have presented their assessment of all of the project's environmental impacts in Appendix 5A. Channel maintenance would promote and improve navigation in the badly shoaled Banks Channel. The project would serve to reconstruct and renourish the beach on the southern end of Figure 8 Island, thus affording additional protection to oceanfront property owners from seasonal and storm erosion.

The purpose of the work is to maintain Mason Inlet within its 1000-foot corridor. Annual dredging may be necessary to minimize the environmental impacts and movement of the inlet. Plans showing work are included with this public notice. This proposal shall be reviewed for the applicability of other actions by North Carolina agencies such as: a. Water Quality Certification under Section 401 of the Clean Water Act by the North Carolina Division of Water Quality (NCDWQ). b. Easement to fill or otherwise occupy State-Owned submerged land under North Carolina General Statute 143-341(4), 146-6, 146-11, and 146-12 by the North Carolina Department of Administration (NCDA) and the North Carolina Council of State. c. Approval of an Erosion and Sedimentation control Plan by the Land Quality Section, North Carolina Division of Land Resources (NCDLR), pursuant to the State Sedimentation Pollution Control Act of 1973 (NC G.S. 113 a-50-66). The State of North Carolina will review this public notice to determine the need for the applicant to obtain any required State authorization. Any person may request, in writing within the comment period specified in this notice, that a public hearing be held to consider this application. Request for the public hearing shall state, with particularity, the reasons for holding the public hearing. The decision whether to authorize a maintenance event will be based on an evaluation of the probable impacts, including cumulative impacts, of the proposed activity and its intended use on the public interest. Evaluation of the probable impacts which the proposed activity may have on the public interest requires a careful weighing of all those factors which become relevant in each particular case. The benefits which reasonably may be expected to accrue from the proposal must be balanced against its reasonably foreseeable detriments. The decision whether to authorize a proposal, and if so the conditions under which it will be allowed to occur, are therefore determined by the outcome of the general balancing process. That decision should reflect the national concern for both protection and utilization of important resources. All factors which may be relevant to the proposal must be considered including the cumulative effects thereof. Among those are conservation, economics, aesthetics, general environmental concerns, wetlands, cultural values, fish and wildlife values, flood hazards and flood plain values (in accordance with Executive Order 11988), land use, navigation, shore erosion and accretion, recreation, water supply and conservation, water quality, energy needs, safety, food and fiber production, mineral needs, considerations of property ownership, and, in general, the needs and welfare of the people. Subject to the preceding sentence and any other applicable guidelines or criteria, authorization will be granted unless the District Engineer determines that it would be contrary to the public interest. The Corps of Engineers and the Department of Environment and Natural Resources is soliciting comments from the public; Federal, State and local agencies and officials; Indian Tribes and other interested parties in order to consider and evaluate the impacts of this proposed activity. Any comments received will be considered by the Corps of Engineers and the Department of Environment and Natural Resources to determine whether to issue, modify, condition or deny authorization for this proposal. To make this decision, comments are used to assess impacts on endangered species, historic properties, water quality, general environmental 2 effects and the other public interest factors listed above. Comments are used to determine the need for a public hearing and to determine the overall public interest of the proposed activity. Written comments pertinent to the proposed work, as outlined above, will be received In the Wilmington Regulatory Field Office, Attn: Mr. Henry Wicker, Post Office Box 1890, Wilmington, North Carolina, 28402, until 4:15 p.m., September 3, 2004, or telephone (910) 251-4930. Comments pertinent to authorization by the Department of Environment and Natural Resources should be mailed to Charles S. Jones, Director, Division of Coastal Management, 1638 Mail Service Center, Raleigh, North Carolina 27699-1638. a "-4�' ` "O* W1�11J1 "� r�? �y,��`1 � I��j� ��.``. ,�8` r �IFiI®1�1®Iplr►y1W1�_ 51 •� {IAS x l '\ r � - t G -il'j ?fir 77� �" �s�>�r��v�,, ,,� .,.��• r;r „a,e, _,,..

S. Army Corps of Engineers Wilmington Regulatory Field Office P. O. Box 1890 Wilmington, North Carolina 28402-1890 WATER QUALITY SECTION Subject: Action ID # 200400895; Figure Eight Island Homeowners Association, Dredging in Banks Channel and Connecting Waters, New Hanover County., North Carolina Dear Mr. Wicker: This letter provides the comments of the U. S. Fish and Wildlife Service (Service) on the subject Public Notice (PN), dated June 30, 2004. The applicant, Figure Eight Island Homeowners Association (HOA)., has submitted an application for processing under the Coastal Area Management Act (CAMA)-Corps permit processing agreement. The PN addresses a proposal to conduct maintenance dredging in estuarine water near Figure Eight Island and place the material removed on the ocean beaches of the island. These comments are submitted in accordance with the Fish and Wildlife Coordination Act (FWCA) (48 Stat. 401, as amended; 16 U.S.C. 661- 667d). Comments related to the FWCA are to be used in your determination of compliance with 404(b)(1) guidelines (40 CFR 230) and in your public interest review (33 CFR 320.4) in relation to the protection of fish and wildlife resources. Additional comments are provided regarding the District Engineer's determination of project impacts pursuant to section 7 of the Endangered Species Act (ESA) of 1973, as amended (16 U.S.C. 1531-1543). Proposed Project The proposed work is described in the Field Investigation Report (FIR), dated June 10, 2004, of the North Carolina Division of Coastal Management (NCDCM) that accompanied the PN and the permit application, dated April 2004, prepared by Criser and Troutman Consulting Engineers of Wilmington. The applicant proposes maintenance dredging of previously authorized channels with the addition of four canal/lagoon areas. The FIR states that the canal/lagoon areas have been added to present "a comprehensive picture of the island's present and future maintenance dredging needs." All excavations would be done by hydraulic pipeline dredge. The proposed dredging is expected to produce 230,000 cubic yards of material. This material would be placed along approximately 10,000 linear feet (1.89 miles) of beachfront on the southern end of the island. The material would be transported by the dredge pipeline and deposited along the beachfront using a temporary protective berm to control effluent run-off. Pipeline corridors would be established to ensure that no marsh areas or sensitive vegetation 2 would be crossed during construction. The material would be used to construct a continuous berm with an elevation of 9.5 feet and a minimum width of 100 feet. The FIR states that approximately one million square feet (22.96 acres) of beach would be filled by the project. All dredging would be done during the winter season when biological activities in both the sound and the beach would be at a minimum. Service Concerns The Service is concerned about the loss of both subtidal and, especially, intertidal habitats. The permit application (p. 2) states that there are one or two small areas where the shoals may be intertidal. Appendix 5A notes (p. 4) that the proposed work would result in the direct loss of 1.3 acres of intertidal sand flats and an additional 0.1 of an acre due to side slope equilibration, presumably the sloughing of soil following dredging. Both areas are important fish and wildlife habitat and the values of intertidal flats in North Carolina have been described (Peterson and Peterson 1979). Shorebirds forage along intertidal habitat of exposed sand bars and beachfronts. Invertebrates inhabiting intertidal shoals are an important food source for shorebirds and fishes. Birds such as the sanderling (Calidris alba), black-bellied plover (Pluvialis squatarola), willet (Catoptrophorus semipalmatus), ruddy turnstone (Arenaria interpres) , greater yellowlegs (Tringa melanoleuca), lesser yellowlegs (Tringa flavipes ), marbled godwit (Limosa fedoa), American oystercatcher (Naematopus palliatus) , clapper rail (Rallus longirostris), and great blue heron (Ardea herodias) are a few of the birds that may forage on intertidal flats in North Carolina (Peterson and Peterson 1979, pp. 49-58). The Service is concerned that the placement of the dredged material on the beach would reduce the habitat value of the beach by significantly altering the physical characteristics of the beach. The permit application states (p. 2) that grain sizes within the interior lagoons and canals are smaller than beach sand. Some dredge sites vary greatly from normal beach sediment. The grain size analysis provided in the permit application shows that Site S-20 is characterized by gray silt and approximately 90 percent of the material passes through a #200 sieve. The FIR states that if significant pockets of extremely fine sediments are encountered, they can be compartmentalized in a temporary dike on the upper dry sand beach, dewatered, and mechanically mixed by bulldozers prior to final grading. The proposal contains no provisions for excluding any of the dredged material from ultimately being placed on the beach. The application also states (Appendix 5A, p. 2) that "a portion of these smaller grain particles will serve to infill the larger voids within the sand on the beach while the remaining suspended particles will settle rapidly in down-drift areas." As noted, data provided in the permit application indicates that much of the material proposed for beach placement is much smaller than sediment presently on the beach. However, an important aspect of the project not addressed by the applicant is the degree to which the existing beach represents a native beach. Pilkey et al. (1998, p. 183) states that before construction began on Figure Eight Island, the developers elevated the ocean side of a portion of the island using sand excavated from finger canals dug on the back side of the island. The permit application discusses a series of dredging projects on the sound side of the island, including original development in 1969 and dredging permitted in 1992 and 1998. All the prior dredging projects 3 resulted in disposal of the dredged sand on the ocean beaches of the island. The Service is concerned that a situation is emerging in which increasingly finer sand is deemed "compatible" with the existing beach because the beach is composed predominantly of sand from prior disposals originating in the same source. As a potential measure of comparison, the Service reviewed the Corps' planning document for a Topsail Beach erosion project (U. S. Army Corps of Engineers 1990, p. eis-2). This document noted that the ocean beach consisted of "medium to coarse sand." While various definitions may exist for medium and coarse grained sand, the Unified Classification of the American Society for Testing and Material (ASTM) considers coarse sand to range from 4.75 millimeters (mm) to greater than 2.00 mm, the coarse- medium boundary to be 2.00 mm, and medium sand to range from less than 2.00 mm to greater than 0.50 mm in grain size. The four median grain size figures given for the disposal beach range from 0.23 mm to 0.35 mm with an average of 0.265 mm. It is likely that at one time the beach on Figure Eight Island was similar to that of Topsail Beach. Existing data would suggest that there has been a significant reduction in sand grain size on Figure Eight and that current data do not reflect what would be considered a native beach. If a beach composed of coarse to medium grained sand is considered as a natural standard, the material proposed for disposal represents a significant departure from the sediment characteristics of the presumed historic beach to which shorebirds and sea turtles are adapted. The issue of grain size compatibility is critical to many aspects of the project's success, such as longevity, and the adverse environmental impacts, such as turbidity and sedimentation. Pilkey et al (1998, p. 183) state that two nourishment projects on Figure Eight Island prior to 1997 were "substantially lost in short periods." This issue is summarized by the statement (National Research Council [hereafter NRC] 1995, p. 97) that: "The most important borrow material characteristic is the sediment size. Borrow material grain size matching the native material is considered synonymous with quality. Fine material also adversely affects project performance. Early projects constructed without regard for grain size performed relatively poorly, and recent developments indicate that nourishment sand that is only slightly smaller than native sand can result in significantly narrower equilibrated dry beach width compared to sand the same size as (or larger than) native sand." A major reduction in grain size has important ramification for both shorebirds and nesting sea turtles. Beach invertebrates which serve as a food source for near shore fishes and shorebirds live in the spaces between sand grains. High energy, intertidal beaches in the southeastern United States may have 20-30 invertebrate species (Ruppert and Fox 1988, p. 346). Invertebrates found here include the beach digger (Haustorius canadensis), a polychaete worm (Scolelepis sguamata), and, in late summer, the mole crab (Emerita talpoida) and coquina clam (Donax sp.). The swash zone is dominated by the mole crab and coquina clam. Greene (2002 and references therein, p. 25) states that both Emerita and Donax are the primary prey base for surf zone fish, crabs, and shorebirds. 4 One important manifestation of the adaptability of Donax and Emerita to the beach-face is their mobility. Both animals move up and down the beach with each wave uprush; and they stay within the swash zone as the tides change by moving out of the sand on the uprush, if they prefer a higher location on the beach, or in the backrush of the waves as the tides fall, if they prefer a lower location. They do this in steps, moving in mass with almost every wave, in an effort to maintain their position in the active swash zone with optional feeding conditions. Therefore, the "health" of the Emerita and Donax is closely linked with the sediment characteristics of the beach, and the availability of natural seawaters surging up and down the beach-face. Extremely critical is sediment grain size because mole crabs do not actually burrow into the beach as they change locations within the swash zone, but rather vibrate their lower appendages and legs to create a "quicksand" condition in their immediate area. This makes it easy for them to penetrate or burrow into the sand with a minimum expenditure of energy. Anything that significantly alters the beach-face sands has the potential to impact Emerita numbers. If the sand is too coarse, too fine, too well sorted, or contains too many heavy minerals (dark sands), mole crabs find it difficult or impossible to burrow into the beach. If the proposed work reduces populations of beach invertebrates, shorebirds would be adversely affected due to a reduction in food resources. The use of finer grained material can produce a harder, more compacted beach. In discussing the beach building at Atlantic Beach (Carteret County) with sediment from the Morehead City Harbor, Bush et al. (1996, p. 85) wrote that mud in sediment is cohesive enough to form small scarps on the beach and packs down into a relatively hard pavement on the upper beach. Pilkey et al. (1998, p. 101) also noted that dried mud has made sections of Atlantic Beach as "hard as rock." A compacted beach would adversely affect sea turtle nesting success. A compacted beach can increase false crawls, increase nest digging time, hinder gas exchange within incubating nests, alter the hydric environment of the nest, and result in broken eggs from clutches deposited in too shallow an egg chamber (National Marine Fisheries Service and U. S. Fish and Wildlife Service [hereafter NMFS and USFWS] 1991, pp. 21-22). In addition to hindering the excavation of sea turtle nests, a hard, compact beach can also be detrimental to proper incubation. Sand grain shape, size, and compaction can alter gas diffusion necessary for proper development and thereby alter hatching success (NMFS and USFWS 1991, p. 22; Greene 2002 and reference therein, p. 30). The Service is concerned that the work may alter the color of the beach. A darker than normal beach color absorbs more heat and increases beach temperature. Alteration of beach temperature during incubation can alter the incubating environment of the nest and in turn affect hatching success and hatchling sex ratios (NRC 1995 and references therein, p. 112). Pilkey et al. (2004, p. 113) state that all natural North Carolina open beaches are light brown to yellow-brown when viewed from a distance due to iron oxide in shell fragments. Beaches may become darker if black shell fragments are added. Black shell fragments originate in oxygen- poor mud of a lagoon or sound where iron is converted to iron sulfide (Pilkey et al. 2004, p. 115). While black shell fragments may result from island migration which reveals ancient lagoon on the beach front, such fragments may also be introduced by sediment placement. If material for beach construction is taken from a lagoon or old dredge material site, it will contain black shells (Pilkey et al. 2004, p. 115). Current project plans do not address the issue of whether the color of the current beach may already have been altered. The sediment analyses in the permit application note that all four beach sites consisted of "gray sand." One possible explanation for the deviation from a yellow- brown color is that black shell fragments remain on the beach from prior placements of material from estuarine water behind the island. The addition of even more estuarine sediment with dark shells would create an even more unnatural environment for the incubation of sea turtle eggs. The Service is concerned that the proposed work could produce harmful turbidity (and subsequent sedimentation) for an extended period. The permit application states (Appendix 5A, p. 5) that the effects of any elevated turbidity would be limited both temporally and spatially. However, if the finer material is mixed prior to beach placement, finer material could be exposed and washed off the beach for an extended period. There may be a deterioration of nearshore habitat quality due to long-term turbidity from the artificial beach-dune system. Bush et al. (1996, p. 83) state that "streams of turbid water from the surf zone of Miami Beach are still responsible for killing coral heads 14 years after the beach was emplaced." Goldberg (1985 as cited in Goldberg 1988) gives an example of a Florida beach nourishment project which resulted in damage to a nearby rocky environment 50-60 meters (164- 197 feet) offshore. Material placed on the beach during a nourishment project quickly eroded off the beach and covered nearshore rocks. Seven years after the project, the rocks were still covered in fine sand and silt, and turbidity of the nearshore area remained high. Besides grain size on the beach, another aspect of beach nourishment that appears to be important with respect to the "health" of Emerita and Donax is water quality, especially turbidity (Reilly and Bellis, 1983). If the source material for a beach nourishment project includes a significant amount of fine-grained sediment (silts and clays), this may not only impact the distribution of Emerita and Donax in the areas of discharge, but also have a more lasting impact on the adults that winter offshore. Reilly and Bellis (1978, p. 58) concluded that the high turbidity following beach nourishment on Bogue Banks was the probable cause for the failure of adult Emerita to return to Fort Macon beach (Carteret County, North Carolina). While increased turbidity per se is harmful, a closely related event, increased offshore sedimentation, also produces adverse impacts. The suspended particles which are transported by water eventually settle to the bottom creating sedimentation. The settling of suspended particles is also referred to as siltation. Offshore hardbottoms (areas with exposed limestone, phosphate, and other sedimentary rock) are valuable biological communities that support a diverse community of algae, soft and encrusted coral, sea anemones, sea whips, and recreationally important finfish (Frankenberg 1997, pp. 191-192). Nearshore reef habitats that lie within the depth of closure may be destroyed by sand burial resulting from the redistribution of beach fill material (NRC 1995, p. 113-114). Studies have indicated that sand placed on Wrightsville Beach has washed off the beach and buried extensive hardbottoms on the inner continental shelf 6 (Riggs, 1994, p. 17). These hardbottoms were prime fishing locations, but are now out of production due to a covering of two to six inches of sand. Riggs (1994, p. 17) concludes that "The business of beach nourishment and hardbottoms represents a very serious conflict, and a problem that's going to get much bigger." The current evaluation of potential adverse environmental impacts does not discuss the presence or absence of nearshore hardbottom which could be harmed by the work. Special Status Species The Service has reviewed available information on federally-threatened or endangered species known to occur in New Hanover County. We have also reviewed information from the North Carolina Natural Heritage Program (NCNHP) database which contains excellent data on the special status species, both federal and state. This database can be accessed by topographic quadrangle (quad) of the U. S. Geological Survey (USGS). Data from USGS quads provide the most project-specific information on species which should be considered in permitting this project. The project area is located near the boundary of the Wrightsville Beach and Carolina Beach quads. The occurrence data of special status species within these quads can be obtained on the internet at < http://www.ncsparks.net/nhp/quad.html >. Our review indicates that the West Indian manatee (Trichechus manatus), a federally-endangered mammal, could occur in the project area. The species is known to occur in New Hanover County and the NCNHP database indicates several reported occurrences in the coastal waters of the county. The shallow, estuarine waters of the project area may provide suitable habitat for manatees that move along the Atlantic Coast during summer months and are seasonal transients in North Carolina, primarily from June through October. Manatees feed in water one to two meters (3.3 -6.6 feet) deep that may support submerged aquatic vegetation. The species moves extensively when in North Carolina waters and past occurrence records cannot be used to precisely determine the likelihood that it will be present at a particular construction site. To protect manatees in North Carolina, the Service developed guidelines entitled "Precautions for General Construction in Areas Which May Be Used by the West Indian Manatee in North Carolina." These guidelines address all types of in-water construction, except blasting, and should produce little, if any, additional expense. The guidelines are intended mainly to ensure that construction personnel are informed that manatees may occur in the work area, that work should cease if a manatee approaches the work area, work should not resume until the manatee leaves the work area, and to provide procedures for reporting the death or injury of a manatee. These guidelines are available on our web site at < http://nc- es.fws.gov/mammal/manatee guidelines pdf> and are attached for your records. The risk to manatees could be reduced to an acceptable level by the implementation of the Service's guidelines. The risk would be further reduced by performing the work during the period of November through May. While seasonal work restrictions would minimize potential direct impacts to manatees and the opportunity for sea turtle nesting, serious concerns remain about longer-term, adverse impacts on the quality of sea turtle nesting habitat. As noted, the proposed work poses a risk of creating a compacted beach which is darker than the beach which may have existed historically. These issues have not been addressed in the permit application or the PN. At this time, the Service cannot concur that the proposed work is not likely to adversely affect federally listed species. Therefore, we request that the Corps prepare a Biological Assessment for Service review prior to the issuance of any DA permit. Service Recommendations: The coordinated federal position (CFP) should recommend denial of the permit due to the fact that potentially significant adverse environmental impacts have not been adequately addressed. To fully address the impacts of the proposed work, the CFP should recommend that an Environmental Assessment (EA) be prepared in accordance with the National Environmental Policy Act (NEPA). Important aspects of this EA should include: 1. A discussion of alternative channel designs, such as reduced widths near intertidal shoals, which would eliminate the need to remove intertidal shoals. There should be a consideration of intertidal shoals and emergent wetlands which may be lost due to substrate sloughing, or slope equilibration, after dredging. If design modification cannot eliminate the direct and indirect loss of intertidal areas and wetlands, compensatory mitigation plans should be presented for these important areas of fish and wildlife habitat; 2. The presentation of the physical characteristics of beaches on Figure Eight Island prior to any placement of sound side sediment on the beaches. Such data, if available, should form the basis for determining the compatibility of the material currently being considered for beach placement rather than existing beach conditions which may reflect several past sediment placements; 3. A complete discussion of changes in the physical characteristics (e.g., loss of interstitial spaces, hardness/compaction, color, organic composition, and moisture content) of the beach which would occur if the proposed sediment placement occurs; 4. An evaluation of the potential for reduced food resources for shorebirds and nearshore fish if the proposed sediment placement diminishes populations of beach invertebrates such as Emerita and Donax after the interstitial spaces to which they are adapted are filled with silt and clay particles; A discussion of the potential for a reduction in the ability of the beach to serve as productive sea turtle nesting habitat. This discussion should address data referenced above which indicates that beach compaction reduces successful nest construction. Furthermore, incubation and hatching success can be reduced when sand grain size, density, shear resistance, color, gas diffusion rates, organic composition, and moisture content differ from natural beach sediment (Greene 2002, p. 30 and references therein); 8 6. An evaluation of the potential for the constructed beach to produce long-term turbidity due to proposed mixing of fine grain material with larger sand grains. The evaluation should consider both adverse impacts to feeding by nearshore fish and the survival of beach invertebrates which utilize nearshore waters; 7. An evaluation of potential adverse impacts to offshore benthic habitats, including hardbottoms, that may occur due to sedimentation of the fine grained material washed off the beach; 8. A discussion of the cumulative impacts of the dredging and sand placement in conjunction with similar work to be performed for the Mason Inlet Relocation Project. Since the applicant has proposed to coordinate this work with the first maintenance event of the Mason Inlet project, the EA should fully consider the overall biological, hydrological, and geological impacts of both projects; and, 9. Finally, there should be sufficient information on project impacts on the West Indian manatee and sea turtle nesting activities to allow the District Engineer to make a determination of project impacts on these species.

The manatee is also listed as endangered under the North Carolina Endangered Species Act of 1987 (Article 25 of Chapter 113 of the General Statutes). The U.S. Fish and Wildlife Service (Service) is the lead Federal agency responsible for the protection and recovery of the West Indian manatee under the provisions of the Endangered Species Act. Adult manatees average 10 feet long and weigh about 2,200 pounds, although some individuals have been recorded at lengths greater than 13 feet and weighing as much as 3,500 pounds. Manatees are commonly found in fresh, brackish, or marine waterhabitats, including shallow coastal bays, lagoons, estuaries, and inland rivers of varying salinity extremes. Manatees spend much of their time underwater or partly submerged, making them difficult to detect even in shallow water. While the manatee's principal stronghold in the United States is Florida, the species is considered a seasonal inhabitant of North Carolina with most occurrences reported from June through October. To protect manatees in North Carolina, the Service's Raleigh Field Office has prepared precautionary measures for general construction activities in waters used by the species. Implementation of these measures will allow in-water projects which do not require blasting to proceed without adverse impacts to manatees. In addition, inclusion of these guidelines as conservation measures in a Biological Assessment or Biological Evaluation, or as part of the determination of impacts on the manatee in an environmental document prepared pursuant to the National Environmental Policy Act, will expedite the Service's review of the document for the fulfillment of requirements under Section 7 of the Endangered Species Act. These measures include: 1. The project manager and/or contractor will inform all personnel associated with the project that manatees may be present in the project area, and the need to avoid any harm to these endangered mammals. The project manager will ensure that all construction personnel know the general appearance of the species and their habit of moving about completely or partially submerged in shallow water. All construction personnel will be informed that they are responsible for observing water-related activities for the presence of manatees. 2. The project manager and/or the contractor will advise all construction personnel that there are civil and criminal penalties for harming, harassing, or killing manatees which are protected under the Marine Mammal Protection Act and the Endangered Species Act. 3. If a manatee is seen within 100 yards of the active construction and/or dredging operation or vessel movement, all appropriate precautions will be implemented to ensure protection of the manatee. These precautions will include the immediate shutdown of moving equipment if a manatee comes within 50 feet of the operational area of the equipment. Activities will not resume until the manatee has departed the project area on its own volition (i.e., it may not be herded or harassed from the area). 4. Any collision With and/or injury to a manatee will be reported immediately. The report must be made to the U.S. Fish and Wildlife Service (ph. 919.856.4520 ext. 16), the National Marine Fisheries Service (ph. 252.728.8762), and the North Carolina Wildlife Resources Commission (ph. 252.448.1546). 5. A sign will be posted in all vessels associated with the project where it is clearly visible to the vessel operator. The sign should state: CAUTION: The endangered manatee may occurin these waters duringthe warmer months, primarily from June through October. Idle speed is required if operating this vessel in shallowwater during these months. All equipment must be shut down if a manatee comes within 50 feet of the vessel or operating equipment. A collision with and/or injury to the manatee must be reported immediately to the U.S. Fish and Wildlife Service (919-856-4520 ext. 16), the National Marine Fisheries Service (252.728.8762), and the North Carolina Wildlife Resources Commission (252.448.1546). 6. The contractor will maintain a log detailing sightings, collisions, and/or injuries to manatees during project activities. Upon completion of the action, the project manager will prepare a report which summarizes all information on manatees encountered and submit the report to the Service's Raleigh Field Office. 7. All vessels associated with the construction project will operate at "no wake/idle" speeds at all times while in water where the draft of the vessel provides less than a four foot clearance from the bottom. All vessels will follow routes of deep water whenever possible. 8. If siltation barriers must be placed in shallow water, these barriers will be: (a) made of material in which manatees cannot become entangled; (b) secured in a manner that they cannot break free and entangle manatees; and, (c) regularly monitored to ensure that manatees have not become entangled. Barriers will be placed in a manner to allow manatees entry to or exit from essential habitat.

PROJECT SUMMARY: The applicants propose to complete maintenance dredging of previously authorized areas in Banks Channel and the waterway connector channel, and also, complete maintenance dredging in the existing lagoon and canal areas. All of the excavated sediments would be utilized for renourishment of the beaclhfront (10,000 LF) at the south end of Figure 8 Island. Figure 8 Homeowners Assoc., Inc. Page 2 8. PROJECT DESCRIPTION Figure 8 Island is a private residential barrier island located in the northeast corner of New Hanover County, adjacent to the Atlantic Ocean and Middle Sound, between Mason and Rich Inlets. The island is accessed from the mainland at the end of Edgewater Club Road (SR 1402), by a private bridge over the Atlantic Intracoastal Waterway (AIWW) and an earthen causeway which traverses Middle Sound. In the project area, the NC Division of Water Quality classifies the waters of the Atlantic Ocean as SB. The waters of Banks Channel, Middle Sound and the AIWW are classified as SA-ORW, and they are OPEN to the harvest ofshellfish. The extensive salt marshes between Figure 8-Islandmandwine Atlantic Intracoastal Waterway are designated as Primary Nursery Area (PNA), by the NC Division of Marine Fisheries, however, in the area of the proposed maintenance dredging, the open water areas of Banks Channel, the finger canals and the waterway connection channel are not designated as PNAs. Over the years, the Figure 8 Beach Homeowners Association have obtained a number of State permits for channel maintenance, beach renourishment, and beach bulldozing. In 1989, the Association initiated the development of a long range plan that addressed channel maintenance and beach restoration on an island- wide basis. The resulting State permits, 426-92 and #21-93, authorized channel maintenance projects at the north and south ends of the island, both with beach deposition of excavated materials. This beach reconstruction project was completed in 1993. The hurricanes of the mid to late 1990's caused extensive damage and created serious erosion of the beach on Figure 8 Island. In March 1998, the applicants were issued State Permit #29-98 authorizing the maintenance dredging of Banks Channel, with beach disposal of the excavated material (previously State Permit #26-92). Subsequently, in 1999, the applicants received State Permit # 12-99 to excavate an existing USACOE spoil disposal island adjacent to the AIWW, and pump the material to the beach at the middle of Figure 8 Island. In 2001, Permit #6-01 was issued to the applicants to dredge a portion of Nixon Channel and renourish the beach at the north end of Figure 8 Island (previously State Permit #21-93). In addition to their own permits, the beach on the southern end of Figure 8 Island was a permitted disposal area for a portion of the beach compatible sands generated from New Hanover County's Mason Inlet Relocation Project (State Permit # 151-01). That renourishment activity was completed in 2002, however, future maintenance dredging associated with that project may again propose to utilize the south end of Figure 8 Island as a disposal area for beach compatible spoils material. The current application proposes to re-establish safe navigation by completing maintenance dredging of the previously authorized channels (State Permits #26-92 & #29-98) and add the four existing (4) canal/lagoons to the area to be maintained. The lagoon and canal systems were originally constructed during the early development of the island and have not needed large-scale maintenance dredging in the past. In fact, except for the shoaling of the entrances to the lagoons (Sounds Point and Salt Meadow), very little dredging is proposed in the lagoon/canal areas. The applicant has included them with this application in an effort to present a comprehensive picture of the island's present and future maintenance dredging needs to be able to maintain existing navigational corridors around the island. All of the excavated material would be used for beach renourishment. The applicant has completed a series of test borings in the proposed dredge area and submitted grain size analysis data of the test results. Grain sizes of the sediments in the canal/lagoon systems were smaller than the beach sands. The applicant proposes that if significant pockets of extremely fine sediments are encountered, they can be compartmentalized in a temporary dike on the upper dry sand beach, dewatered and mechanically mixed by dozers prior to final grading. Figure 8 Homeowners Assoc., Inc. Page 3 The proposed project includes the following areas: 1. Banks Channel - 7,750' X 125' X -9' MLW. 2. Waterway Connector Channel - 1,850' X 125' X -9' MLW. This includes the 600 LF section connected to Banks Channel, the 800 LF section previously permitted at the channel's connection to the AIWW, and a proposed 450 LF extension on the east end of the waterway connection channel. 3. Backfin/Causeway Canal - 2,450' X 125' X -9' MLW 4. Sandy Point Canal - 2,200' X 125' X -9' MLW 5. Backfin Canal - 1,700' X 100' X -9' MLW 6. Sounds Point Lagoon - 800' X125' X 9' MLW Sounds Point Lagoon Entrance - 200' X 300' tapering to 100' X -9' MLW 7. Salt Meadow Lagoon - 2,800' X 125' X -9' MLW Salt Meadow Lagoon Entrance - 200' X 300' tapering to 100' X -9' MLW All excavation would be completed by hydraulic pipeline dredge. The south end of the project would terminate approximately 200 feet south of the southern-most lagoon (Sounds Point), as authorized in the 1998 permit (#29-98). The excavated sand sediments would be pumped to the southern end of the Figure 8 Island oceanfront (up to 10,000 LF) to be utilized in beach renourishment and reconstruction. The resulting beach profile is anticipated to be a continuous bean, constructed to approximately 9.5 feet elevation, with a minimum width of 100 feet, tapering toward the ocean at an approximate 20:1 slope. It is estimated that approximately 230,000 cubic yards of medium to fine grain sandy material would be generated from the proposed maintenance excavation. 9. ANTICIPATED IMPACTS The project would result in the excavation of 2,481,250 square feet (56.96 acres) of subtidal, shallow bottom within the combined project areas of Banks Channel, the waterway connector channel, and the canal/lagoon system. Approximately 56,628 square feet (1.3 acres) of that total would be inter-tidal sand flats. The only area not previously authorized for excavation is the proposed extension of the waterway connection channel (450' X 125' X -9' MLW). The projected 230,000 cubic yards of dredged sand sediments would be placed on the southern end of Figure 8 Island's upper beach shoreline (10,000' X ±200'). The dredging and beach renourishment activities would create short-term turbidity, as well as, impact the intertidal macro fauna and benthic communities within the proposed excavation and spoil disposal areas. The applicant contends that adverse impacts would be minimized by timing the project to avoid periods of peak biological activity and outside of sea turtle nesting season, and that affected species populations would return to pre-project distributions within one or two years. The applicant's consultants have presented their assessment of all of the project's environmental impacts in Appendix 5A. Channel maintenance would promote and improve navigation in the badly shoaled Banks Channel. The project would serve to reconstruct and renourish the beach on the southern end of Figure 8 Island, thus affording additional protection to oceanfront property owners from seasonal and storm erosion.

Q NARRATIVE DESCRIPTION MAINTENANCE DREDGING (BANKS CHANNEL ' BEACH RE-BUILDING FIGURE EIGHT ISLAND, NORTH CAROLINA APR 6 ' pIVIS?ON ? EMENT Background CDASTA- MANA ' The small boat and navigation access channels which connect Banks Channel and connecting bays with the Atlantic Intracoastal Waterway (AIWW) have shoaled ' and shifted since Hurricanes Fran and Bertha in 1996, Bonnie in 1998, and Dennis and Floyd in 1999, making navigation difficult and dangerous. Correspondingly, the oceanfront of Figure Eight Island has suffered an accelerated rate of erosion, depleting ' material on the open beach and seriously eroding the primary dunes on the upper beach in this area. ' The proposed project is for the maintenance of the navigation channel and the rebuilding of the ocean beaches on the southern portion of Figure Eight Island. The area to be dredged is the same area previously dredged in prior projects with the ' possible exception of a portion of the channel that connects Banks Channel to the Atlantic Intracoastal Waterway ("Waterway Connector Channel"). There is no known documentation of whether this connector channel has been dredged, but it has been ' continuously used for navigation since Figure Eight was developed beginning in the mid-to-late 1960s. The channel existed as a natural channel prior to the 1960s and its use by fishermen, hunters and other recreational users prior to the development of ' Figure Eight is known to older residents of the area. This navigation channel currently serves as the only viable connector to the Intracoastal Waterway for 197 sound side property owners. An 800' section of the connector channel beginning at the AIWW has t been previously dredged. The remaining portion of the waterway connector is approximately 2,900'. ' The history of permits for the navigation channel is set forth in Attachment B to Form MP-1. The history discloses that much of the navigation channel was dredged during the original development in 1969 with a 300' authorized width and a -18' ' authorized depth. A small project by consortium of homeowners was implemented in 1985 primarily for the purpose of obtaining sand for an experimental beach protection project. ' The original 1992 permit authorized the dredging of a 125' x 5,500' channel behind the southern end of Figure Eight with the southern extent of dredging extending to the 1992 location of Mason Inlet. The 1992 project was twice modified. The first modification added the entrances to the two lagoons. The second modification ' extended the project northward to cover all of Banks Channel as well as an 800' long area where the waterway connector meets the AIWW. In 1992 Mason Inlet was located slightly farther south than its current location. ' The permit apparently allowed connection of the southern end of the channel to the throat of Mason Inlet, but the actual dredging stopped a few hundred feet north due ' to lack of funds and contractual commitments. NARRATIVE DESCRIPTION 5272 - 4.13.04 Page 1 ' The 1998 permit allowed dredging in the same location and to the same dimensions as the modified 1992 permit with the exception that the dredging was terminated 200' south of the southern lagoon rather than extending southward to the 1992 location of Mason Inlet. The 1998 permit also allowed wider and deeper connections between the two lagoons and Banks Channel. Figure Eight did the work authorized in the '98 permit but dredged only -6' MLW due to an agreement with Shell Island Resort. All of the prior projects resulted in disposal of the dredged sand on the ocean beaches of Figure Eight south of the causeway. The 1969 permit may have ' also resulted in disposal of sand on upland areas other than the active ocean beach. Project Description ' Maintenance dredging is proposed in the sub-tidal shoal areas in the generally open water area of Banks Channel and the Waterway Connector Channel. There are one or two small areas where the shoal areas may be intertidal. Banks Channel and the Waterway Connector Channel are the primary navigation channels as well as the ' main hydraulic channels for the sound area behind Figure Eight. These channels have been relatively stable through the years but hurricane activity mentioned before, which had high water beach overwash along with storm-level erosion, created some ' redistribution of shore and bottom sediments. Also the long term instability of Mason Inlet as it migrated southward contributed to a higher level of sediments to the navigation channels. In 2002 the Inlet Relocation Project created another unstable condition at the inlet and its sediment basins and resulted in more sediments being fed into the navigation channel. ' The creeks connecting to Banks Channel have been choked in some locations due to this higher level of sedimentation. This project will offer the additional benefit of restoring flows so as to allow natural processes to rechannel these creek mouths. ' All of the sand materials removed will be discharged along approximately 10,000 linear feet of beachfront, extending from the southernmost lots northward. A ' transition adapted to the existing beach profile approximately 300 to 400 feet long will be provided at both ends of the beach fill. The basic dimensions of the beach fill will be to an elevation of approximately 9.5' mean sea level (MSL) with a berm width of at ' least 100'. The ocean side of the berm will be shaped to an approximately 20:1 slope between elevation 7 and -2.0' MSL (see sheets 1 and 3 of the permit application for sketches of beach fill location and proposed beach profile). It is estimated that ' approximately 230,000 cubic yards of medium to fine sand materials will be excavated from the proposed area to be dredged by hydraulic pipeline dredge. The material will be transported by the dredge pipeline and deposited along the beachfront using a temporary protective berm parallel to the shoreline to control the effluent run-o rte, ensuring maximum upland beach deposition of the material and minimizing i i within the surf zone. r I I NARRATIVE DESCRIPTION 5272 - 4.13.04 Page 2 n \SOA O PSG PN- M P G All excavations are to be done by hydraulic pipeline dredge. All materials excavated will be ' pumped to selected beach locations to reconstruct the beach sections as described above. Pipe- line corridors will be established to ensure that no marsh areas or sensitive vegetation will be crossed during the operation. All dredging will-be done during the winter season when biological ' activities in both the sound and beach areas will be at a minimum. ' Test borings and sand samples were taken during March 2004 along the length of the pro- posed channel maintenance dredging areas and on the ocean beach as shown on the sample lo- cation map of the attached report (Appendix 6a). The sampling and testing were done by an in- dependent geotechnical contractor with one sample extracted from the near-bottom area and a second sample at -9 MLW. A grain size analysis of the materials sampled is attached hereto. Current visual observation of the areas to be dredged and visual observation of the material ' dredged in 1999 indicate that the current sediments are essentially the same as those dredged in 1993 and 1999.

Q DoT W a Q J u Environmental Impacts APPENDIX 5A General In general, the environmental impacts resulting from the work proposed in this project will be relatively minimal in that all the work will be accomplished during the winter season when biologic activities are at a minimum. Channel bottom areas that will be disturbed during dredging operations have either been previously dredged during the original island development and channel maintenance operations or used continuously for navigation purposes. The run of Banks Channel north and west to the Intracoastal Waterway represents the primary means of access to regional fishing areas and navigable ocean inlets for boat owners on the southern half of Figure Eight Island. Banks Channel is also a protected area for water skiing. Waterway Connection Along with the dredging of the main run of Banks Channel, CAMA Permit 29-98 also authorized an 800' long dredging area from the Intracoastal Waterway into the northwest end of the connector to Banks Channel. The current proposal includes this 800' segment with a 450' extension to the east to cover an area currently shoaled to less than -5' mlw. This is the most shallow channel area between the waterway and Banks Channel and currently impacts navigation for larger boats. The applicant is currently coordinating with NCDMF to perform a shellfish survey within the 450' extension to determine the presence and abundance of any resource. Navigation/Shoaliniz In 2002, New Hanover County moved Mason inlet approximately 3000' north of its former location. Since that time, the inshore areas have experienced significant sand deposition with the formation of the flood shoal system. Currently, extensive shoal areas exist from roughly the location of the entrance to the southern lagoon southward for a distance of over 2000' to the inlet and entrance to Mason Creek. The proposed excavation area for this portion of the project has been designed to minimize impacts to intertidal shoals by generally aligning with the 0' mlw contour at the southern extent as shown on sheet C7. Excavation will not extend beyond 200' south of the southern lagoon entrance. Navigation from Banks Channel to the south to reach either the ocean through Mason Inlet or the waterway through Mason Creek will continue to be unreliable and potentially hazardous. The applicant understands that New Hanover County will be moving forward with seeking ' authorization for the first maintenance event for the Mason Inlet Relocation Project. While .s a separate, distinct project with a different purpose, the applicant is willing to coordina it h ' County in an attempt to utilize the same dredging contractor to perform both pr . e single mobilization effort, provided that both projects are authorized for e dredgin season. This coordination has the potential to minimize overall disturbanc 5272 - 4.22.04 \Cb 5(P 00P 1 I 0 Lagoons and Canals The lagoons and canal system originally formed during island development are proposed to be maintained as part of the project. At present, the lagoon entrances are impacted by subtidal shoaling, which inhibits tidal circulation and could impact the levels of dissolved oxygen within the lagoons. Clearing shoals from the lagoon mouths will provide optimal flushing and navigation safety. Beach Disposal Much of the area to be dredged consists of deposited sand set into motion by hurricane activity and the relocation of Mason Inlet. The origin of most of the material to be dredged from Banks Channel is the ocean beach itself. Through littoral drift, flood shoal formation processes and storm effects, the sand has accumulated most noticeably within the southern quarter of the proposed dredging area. Soil samples were taken in March, 2004 to determine the relative soil characteristics of the beach and sound area. Beach samples tested similar to those taken in 1992 with that near the southern end slightly finer (in gradation) than that from the center of the beach segment. Samples taken in Banks Channel show a slightly smaller median grain size than that from the beach strand. This can be explained as a normal indication of the smaller particles becoming water-borne and carried inside the inlet to form alluvial deposits. Grain sizes within the interior lagoons and canals are also smaller than beach sands. It is felt however that a portion of these smaller particles will serve to infill the larger voids within the sand on the beach while the remaining suspended particles will settle fairly rapidly in down-drift areas. Should pockets of extremely fine sediments be encountered, these materials will be compartmentalized within a temporary diked area on the upper dry sand beach, allowed to dewater and then mixed mechanically by dozers before final grading. The removal of these deposits from the lagoons and canals will ultimately allow better water circulation and flushing as well as restore original navigation safety. The environmental impacts resulting from the disposal of the dredged material on the beach should be similar to or less than those of authorized past nourishment projects on Figure Eight Island or Wrightsville Beach. The deposition of material on the beach will occur between November 15th and March 31s' in order to avoid impacts to turtle nesting and migration. No hopper dredges that have the capability to entrain turtles will be utilized during the project. As with similar former projects here, there is no reason to believe the sediments to be excavated and deposited on the beach have been exposed to any environmental contamination event. In order to minimize the amount of turbidity and suspended sediments in the surf zone, a diversion berm formed parallel to the shoreline and generally centered on the 0.0 MSL contour will prevent the sand and water mixture pumped to the beach from flowing directly into the surf. The 200'+ berm, maintained in advance of the discharge pipe, will allow the maximum amount of particulate settling before allowing the water to return to the ocean. Following mechanical shaping of the upper dry sand beach in the disposal area and after the actions of several tidal cycles, the resulting beach profile is anticipated to slope at 15 to 20:1 above MHW and 20 to 30:1 below MHW out to just beyond the MLLW contour. The beach will be monitored the April following the project to remove any escarpment that may present an impediment to? nesting. vo PQ??6 of M?N? MN PNPG? 5272 - 4.22.04 2 GO I Coastal Wetlands/PNA's/SAV's No areas of vegetated coastal wetlands are to be directly excavated by the proposed project. The planned channel dredging will occur far enough offshore of natural marsh areas so as to allow for an equilibrated side slope of 3:1 (sloughing and run-out areas) to form without threatening these mature stands of vegetation. Within the larger man-made lagoon, maintenance excavation will take place near the outer edge of three volunteer marsh fringes with the potential for indirect sloughing effects. The channel excavation work will not be performed within any Primary Nursery Area (PNA) as designated by the NC Division of Marine Fisheries. No areas of submerged aquatic vegetation (SAV's) are known to exist south of Pender County. The dredge pipeline will be oriented to cross the shoreline in areas that do not have a coastal wetland fringe or 404 wetlands. Essential Fish Habitat (EFH) Essential Fish Habitat (EFH) provisions of the Magnuson-Stevens Fishery Conservation and Management Act help to maintain marine fishery habitat quality and quantity through National Marine Fisheries Service (NMFS) and regional fishery management council consultation on proposed projects that may affect fishery managed species either directly or indirectly. The proposed area of maintenance dredging and associated beachfront disposal is located in an area identified as EFH for postlarval, juvenile, and adult red drum (Sciaenops ocellatus), bluefish (Pomatomus saltatrix), summer flounder (Paralichthys dentatus), cobia (Rachycentron canadum), brown shrimp (Penaeus aziecus), pink shrimp (Farfantepeneaus duorarum), and white shrimp (Farfantepeneaus setiferus). Juvenile and adult gag grouper (Nycteroperca microlepsis), gray snapper (Lutjanus griseus), king mackerel (Scomberomorus cavalla), spanish mackerel (Scomberomorus maculattts) may also utilize EFH of the area. Table 1 provides a list of all EFH species (including life history stage) present in Middle Sound and Mason Inlet. Other estuarine-dependent species including spot (Leiostomus xanthurus), Atlantic menhaden (Brevoortia tyrannus), and striped mullet (Mugil cephalus) that serve as prey for fisheries managed species (e.g. snappers, groupers, tuna, and sharks) inhabit the Middle Sound complex. Categories of EFH within and adjacent to the project area include estuarine emergent wetlands, intertidal/subtidal bottom habitats, oyster/shellfish beds, and estuarine/marine water column. The Fishery Management Plan Amendments of the South Atlantic Fishery Management Council (FMC) have targeted specific categories of EFH and Habitat of Particular Concern (HAPC) as depicted in Table 2. Table 3 provides an impact summary for all designated categories of E? and HAPC. While all twenty-six (26) habitat categories occur in waters of the s a?? United States, only those existing within or adjacent to the project area a ?n is evaluation. ,? 6 Zpp? Impacts on Estuarine Emergent Wetlands o' F MEN h O As discussed above, there will be no direct impacts to emergent wetlan m At disposal activities. The dredge corridor within Banks Channel and co tingfe be located sufficiently waterward of the existing marsh complex to allow forated side- 5272 - 4.22.04 3 1 slope of 3:1 without any disturbance to marsh vegetation. The potential exists for indirect impacts (from side slope equilibration) only to volunteer marsh fringe within the larger man- made lagoon. Impacts on Intertidal Flats (including sand and mud bottom habitats) Intertidal flats and subtidal bottom will be directly impacted by the removal of sediment accumulating within Banks Channel and connecting waters. Nearly the entire length of the proposed dredge corridor, however, has been dredged under previous CAMA permit authorizations. The only area not previously permitted for dredging is the 450-ft extension located near the Intracoastal Waterway (as discussed above). The entire project area represents an area traditionally used for recreational boating and navigation. Based upon recent detailed hydrographic surveys of the area, much of the proposed dredge corridor is located over subtidal bottom habitat. Of the approximately 57.1 ac to be dredged, 1.3 ac consists of intertidal sand flats. Side slope equilibration may equal another .1 ac (1.4 ac total). The excavation of these intertidal areas will result in the conversion of intertidal sand flat to subtidal bottom (average design depth of - 9 ft MLW). Fish species (particularly summer flounder) utilizing this type of habitat as resting areas during migration to and from back-barrier marsh complexes will be displaced to adjacent intertidal sand flats. Typically, larval and post- larval summer flounder drift and migrate inshore during the late winter, while sub-adults migrate offshore during the late summer and fall. Though temporary disturbance/displacement may occur, this area of intertidal flats is relatively small in proportion to the expanse of unvegetated intertidal habitat located adjacent to the project area. Benthic prey items of fish populations utilizing sandy intertidal areas will be subject to abrupt impact from dredging and beach disposal activities. However, studies have indicated relatively quick regeneration of benthic populations along the beachfront. Reilly and Bellis (1978) reported that population regeneration occurs within 1 to 2 seasons once pumping operation ceases. Essink et al. (1998) reported that species densities, biomass, and diversity of the zoobenthic community of beachfront habitats returned to pre-project values within one to two years. Other studies (National Research Council, 1995; Hackney et al., 1996; Ross and Lancaster, 1996) suggest that benthic species recovery in intertidal areas of both the beachfront and back-barrier island flats will occur rather quickly provided certain mitigative measures (i.e. avoiding peak recruitment periods) are employed. i Project activities will result in direct disturbance to estuarine, subtidal and intertidal habitat. These habitat types are continually subject to natural dynamic forces (e.g. waves, wind, and storm events) that drive depositional processes. As a result, species utilizing this habitat are 1 continually adapting to changes in substrate elevation and surface area. In addition, the dredge corridor represents an area historically maintained and dredged. Processes contributing to the formation of intertidal habitat outside the project area will not be affected. The expanse of 1 intertidal flats beyond the project area will continue to be utilized by the listed fish species. Therefore, the cumulative effect of maintenance dredging and nourishment to intertidal fl is not considered to be significant. ?J ?co 1 ?J 6 Of 0 5272 - 4.22.04 V\'J \ .'w i J0P's N- r Oyster Reefs and Shellfish Beds Intertidal oyster reefs and subtidal oyster beds provide important ecosystem functions including structural complexity for refuge, water column filtering, and feed habitat for resident and transient species (Coen et al. 1999). Marine invertebrate species such as polychaetes, crabs, and amphipods that reside within oyster reef communities serve as important prey items for red drum, summer flounder, striped bass, and other finfish species (Noble 1999). As such, oyster reefs have been designated as EFH by the South Atlantic Fishery Management Council. No oyster reefs are located within the project area. Scattered oyster beds are located along interior creeks of Middle Sound with some occurring near marsh edges of open water. However, the area of the proposed dredge corridor will be located a sufficient distance from marsh edges as to avoid disturbance to any potential oyster beds. In addition, the applicant has coordinated with the NC Division of Marine Fisheries (DMF) to identify the presence of potential shellfish resources in the project area. Available shellfish survey data from DMF indicate that no oyster or clam resources were present from sampling within the mapped habitat type to be impacted by the project. Therefore, it is unlikely that the proposed activities will impact this category of EFH. Impacts on the Marine and Estuarine Water Column ' Mortality of organisms lacking the ability to escape the suction field of an operating dredge and subsequent entrainment in the flow of water and sediment passing through its pumping equipment is likely. However, previous USACE studies have demonstrated that only an extremely small percentage (a fraction of I %) of marine and estuarine larvae are subject to entrainment based upon the amount of water that a dredge can pump. Dredge entrainment impacts to bottom-dwelling fish, crabs and free-swimming larval organisms is anticipated to ' approximate those of other authorized navigation projects. No significant impact on these life forms is expected at local or regional population levels. During beach deposition, immediate localized impact from abrupt increases in sedimentation along the surf zone may negatively affect fish present at the time of the proposed work. However, siltation and turbidity within the surf zone will be minimized through the use of a 1 diversion berm (see description above). Placement of sediment consisting predominantly of medium to fine grain size sands will minimize turbidity and/or other water quality impacts. According to USACE (1997), sediment consisting of more than 90% sand is not likely to produce significant turbidity. These design elements will minimize water quality impacts and subsequent disturbance to estuarine-dependent and surf zone fishes. Effects of any elevated turbidity will be limited both temporally and spatially. Turbidity levels tend to decrease ra? L subsequent to dredging or excavation through simple mixing and dilution cess s i with tidal currents and wind). Indeed, storm events can produce e 1 is of suspended sediments. The spatial scale of elevated turbidity related Jje' is ofte n ir? (USACE 2001). 1? 1U`+ N pF No quantitative assessments have been conducted to evaluate beach nent ,?pAEA zone fishes in this area. It is understood that federal agencies are currentl ng an integrated monitoring plan to gather data with which to identify more&IM?ately potential 5272 - 4.22.04 5 impacts to fishes utilizing the immediate shoreline area. NMFS has commented that restricted lateral movement of early life stage fishes may make these individuals more susceptible to nourishment impacts. More mobile sub-adult and adults that prey upon benthic macrofauna of ' the surf zone (e.g. mole crabs and coquina clams) would likely move to adjacent undisturbed beach areas and other suitable feeding areas for the temporary period of benthic population re- establishment. It should be noted that the beach disposal area to be used is located entirely ' within the footprint previously permitted for the Mason Inlet Relocation Project. ' Impact Summary for Essential Fish Habitat Of the twenty-six (26) categories of identified EFH within southeastern United States, four categories (estuarine emergent wetlands, estuarine water column, marine water column, and intertidal/subtidal bottom) occur within or adjacent to the project area (refer to Table 3). Negative impacts associated with dredging and nourishment activities will be relatively short- term and confined predominantly to the three- to four-month project window. The project site has been historically dredged and maintained for recreational boat use. There will be no disturbance to natural areas of coastal wetlands. The cumulative impact to fish habitat resulting from the proposed activities is considered to be minor and short-lived. Therefore, negative impacts to EFH associated with dredging of Banks Channel and connecting waters and the disposal of material on the beachfront of Figure Eight Island have been determined to be not significant. fl 5212 - 4.22.04 (?• ?? lam} \y?

Project No. 22.10835 Engineering Consulting Services, Ltd. (ECS) has completed the subsurface exploration and laboratory testing for southern Figure Eight Island and Banks Channel in Wilmington, North Carolina. ECS obtained soil samples from twenty selected locations in the sound side channel and in four selected test locations on the beach. The channel locations were denoted as S-1 through S-20. The beach locations were denoted as B-1 through B-4. The channel soil samples were obtained at the bottom of the channel at the selected locations and at an approximate depth of nine feet below the mean low water level. The beach samples were obtained at the surface at the mid-tide level of the beach. This report presents the results of our laboratory tests. We appreciate the opportunity to provide laboratory services to you on this project. Should you have any questions, please contact us at (910)-686-9114.

Project No.: 22.10835 1.0 PROJECT OVERVIEW 1.1 Project Description and Scope of Work This report presents the results of our field soil sampling and laboratory tests for the Figure Eight Island located in Wilmington, North Carolina. The Project Location Diagram in the Appendix A shows the location of the site and the approximate location of the soil samples obtained. Our exploration consisted of obtaining soil samples in the channel and on the beach at twenty four selected locations. The sample locations were selected by Criser and Troutman Consulting Engineers. The soil samples from the channel were obtained at the bottom of the channel and at a depth approximately nine feet below mean low water. The soil samples from the beach were obtained at the surface at the mid-tide level of the beach. In conjunction with the field sampling, laboratory testing was performed to characterize the soil samples obtained from the sampling operations. The purpose of this investigation is to visually classify the soil samples and to perform grain size analysis for each sample. 2.0 FIELD EXPLORATION 2.1 Exploration Procedures 2.1.1 Field Testing The soil samples were obtained using a barge mounted rotary drilling rig, which utilized various cutting bits to advance the boreholes to collect the samples at the designated depths. 3.0 EXPLORATION RESULTS 3.1 Site Conditions 0 The channel is on the sound side of Figure Eight Island and south of the ge from thg mainland. ApR 1 1 N °?- 3.2 Soil Conditions and Description plv ?S1?N'40- co STAL M During our investigation at the twenty four selected locations, we encountered typical native soils in each of the samples at this site. The subsurface soils consisted of silty sands, sandy silts, and clean sands. The depths tested vary from location to location due to the natural contours of the bottom of the channel and due to changes in the tide height that occurred during sampling operations. Based on site conditions, we were able to obtain 30 samples from the channel locations instead of the requested 40 samples. The sample depths were adjusted to account for variations in the tide level during sampling operations. III Report of Field and Laboratory Testing Figure Eight Island Wilmington, North Carolina ECS, Ltd. Project No.: 22.10835 4.0 LABORATORY TESTING 4.1 Laboratory Testing Program The laboratory testing program consisted of performing moisture content tests and grain size analysis on the soil samples. All data obtained from the laboratory tests are included in Appendix B and Appendix C of this report. The soil samples collected for this investigation will be retained at our laboratory for a period of sixty (60) days, after which they will be discarded unless other instructions are received as to their disposition. 4.2 Visual Classification An experienced soil engineer classified each soil sample collected based on the texture and ' plasticity in accordance with the Unified Soil Classification System. A brief explanation of the USCS is included with this report and provided on the grain size graphs. 4.3 Laboratory Testing Methods 4.3.1 Grain Size Analysis Tests The sieve analysis is performed by placing a dry soil sample, of known weight in a series of sieves which is moved in a lateral and vertical motion accompanied by jarring to keep the sample continuously moving over the sieves. The amount of soil retained on each sieve is recorded and plotted on a graph with the weight retained on a given sieve on the y-axis, and the sieve openin on the x-axis. ?? The following sieves were used, as requested by Criser and Troutman, et e the distribution of particle sizes of the soil samples: #4, #10, #20, #40, #60, # and # 2I.?QQ4 SUMMARY OF LABORATORY TEST RESUL PQR 1 ?M0-1 -,??l?st, QNa Beach Samples ' P Mid Tide Sam les Gray Sands Gurl- p B-1, B-2, B-3, B-4 Channel Sam ples Gray Sands with shell Brown Sands Gray Silty Sands Gray Silts First Sample (S-1) S-1, S-2, S-3, S-7, S-5 S-6 S-10 S-8, S-12, S-14, S-20 (Bottom of Channel) S-13, S-16 , , S-15, S-17, S-19 Second Sample (S-2) S-1, S-2, S-3, S-6, S-11 S-9 S-11 S-17, (Elevation -9 MLW) S-7, S-10, S-18 , S-18 2 k;J Jill �7 MIA - Jill --r-- - I- W -01i§ -;i- Z'- 14- LU = 0 Q.In Uj w z w CY V) APPENDIX B X11 LABORATORY TEST RESULTS FOR THE BEACH SAMPLES vo PQ? 16 N of GOPS?P?'1 Unified Soil Classification System (ASTM Designation D-2487) Major Division Group Symbol Typical Names Classification Criteria GW Well-graded gravels and gravel- C„ = D,,/DIo Greater than 4 „ .? sand mixtures, little or no fines C? = (D30)2/(DlOxD60) Between 1 and 3 co v ?
