Section Chief FROM Jessi Baker DMF Habitat Alteration Permit Reviewer SUBJECT Village of Bald Head Island Terminal Groin Draft EIS Scoping DATE Apr119 2012 The North Carolina Division of Marine Fisheries (DMF) submits the following comments pursuant to General Statute 113 131 Representatives from DMF attended an agency scoping meeting in Wilmington NC for the Village of Bald Head Island (VBHI) terminal groin on March 28 2012 DMF has reviewed the Corps of Engineers Public Notice and the Bald Head Island Terminal Groin Work Plan for installing a terminal groin The VBHI proposes to install a terminal groin with supplemental beach nourishment at the west end of South Beach (or The Point ) at the southernmost extent of the existing sand bag groin field The 2010 Coastal Habitat Protection Plan (CHPP) summarizes the latest scientific information available to assess the status and threats to marine fish habitats The CHPP process brings state regulatory agencies together to implement the recommendations from the CHPP The CHPP states that research is needed to determine when and where recruitment to adult fish stocks is limited by larval ingress to estuarine nursery habitats The CHPP also states that the long term consequences of hardened structures on larval transport and recruitment should also be thoroughly assessed prior to approval of such structures DMF has concerns that terminal groins will alter larval transport and impact important fish habitats through altered beach and nearshore sediment and profile Impacts to Larval Transport Terminal groins can potentially interfere with the passage of larvae and early juveniles from offshore spawning grounds into estuarine nursery areas Successful transport of larvae through the inlet occurs within a narrow zone parallel to the shoreline and is highly dependent on along shore transport processes (Blanton et al 1999 Churchill et al 1999 Hare et al 1999) Obstacles such as betties adjacent to inlets block the natural passage for larvae into inlets and reduce recruitment success (Kapolnai et at 1996 Churchill et at 1997 Blanton et al 1999) (from 2010 CHPP) DMF requests a detailed scientific field investigation analysis and modelling of larval transport dynamics that exist around Bald Head Island This information should be used to model estimated impacts of the groin to larval ingress and egress through the inlet f RECEIVED MAY 01 2012 North Carolina Department of Environment and NataakqW%lbcea., Division of Marine Fisheries Impacts to Fish Habitat DMF has significant concerns about the use of hardened shoreline stabilization techniques along high energy ocean shorelines due to accelerated erosion in some location along the shore as a result of the longshore sediment transport being altered These structures may also modify sediment grain size increase turbidity in the surf zone narrow and steepen beaches and result in reduced intertidal habitat and diversity and abundance of macroinvertebrates Anchoring inlets may also prevent shoal formation and diminish ebb tidal deltas which are important foraging grounds for many fish species (Deaton et al 2010) Changes to the surf zone or inlet could affect species that depend on these areas for nursery spawning or foraging DMF requests a field investigation of the current distribution of larval and juvenile fishes in the vicinity of the inlet and the proposed groin location These data can identify the most highly utilized habitat areas as well as serve as baseline data to compare to larval and Juvenile fish monitoring data that should be collected after groin construction Due to the potential for altered sediment grain size beach profile and intertidal habitat due to the influence of a groin DMF requests benthic macroinvertebrate monitoring within the impact area of the proposed groins Based on these concerns DMF also requests detailed discussions of the following be included in the EIS • All Essential Fish Habitat (EFH)and state protected habitats that occurs in this area • All fish habitats outlined in the most recent NC Coastal Habitat Protection Plan (CHPP) that occur in the area • Characterization of and potential impacts to fish and invertebrate community composition and abundance in the inlet and adjacent surf zone at Bald Head Island • Compilation of relevant research regarding larval transport through inlets especially inlets with hardened structures • Potential impacts to the benthos of the surf /swash zone and nearshore areas and a detailed plan to monitor for impacts within the impact area of the proposed groins • Potential impacts to commercial or recreational fishing including any indirect economic impacts due to adverse impacts to fish and fish habitat • Potential direct impacts from dredging beach placement and nearshore placement of sand and how those impacts will be minimized • Potential impacts on regional sand budgets If the USACE would like assistance in

Directo Re Construction of a Terminal Groin at the Juncture of Bald Head Island and the Entrance to the Cape Fear River SAW 2012 00040 Brunswick County ER 12 0437 Dear Mr Timpy We have reviewed the above public notice concerning proposed plans to construct a terminal groin at the juncture of Bald Head Island and the entrance to the Cape Fear River Your agency and the applicant should be aware that the Office of State Archaeology underwater research files have references to extensive maritime activities and shipwreck losses in the general project vicinity therefore much of the project area holds a high potential for containing submerged cultural resources Three known shipwrecks (La Rosa de Bilbao 1804 Ella 1864 USS Violet 1864) and two probable shipwrecks are located within less than one mile of the proposed groin While no known archaeological sites are within the project boundaries the project area has never been systematically surveyed to determine the location or significance of submerged cultural resources As the project creates a bottom disturbance that may damage unknown elements of our underwater cultural heritage we recommend that a comprehensive survey be conducted by an experienced archaeologist to identify the presence and significance of submerged archaeological remains lying within the project boundaries Potential effects on these resources should be assessed prior to the initiation of construction activities A list of archaeological consultants who have conducted or expressed an interest in contract work in North Carolina is available at http / /ww,.v archaeology ncdcr go-,,/ nc lrch /resource /consultints htm The archaeologists listed or any other experienced archaeologist may be contacted to conduct the recommended investigation These comments are made pursuant to Section 106 of the National Historic Preservation Act of 1966 North Carolina legislation (G S 121 22 to 28 Article 3) and the Abandoned Shipwreck Act of 1987 (P L 100

Village of Bald Head Island Terminal Groan Scoping Comments Corps Action ID# SAW - 2012 -00040 Dear Mr Timpy Please accept these comments regarding the needed scope of the Environmental Impact Statement (EIS) that will be prepared to evaluate a possible terminal groin at the Village of Bald Head Island to address the erosion at the western end of South Beach These comments are based upon the federation s experience with beach and inlet management in North Carolina and participation in the development of numerous environmental reviews for beach and inlet management projects In addition our direct participation in the development of terminal groin legislation in North Carolina during 2011 (NC General Assembly Senate Bill 110) as well as at the scoping meeting held by the Corps on March 8 2012 allow us to provide some insights into issues that need to be thoroughly vetted by this environmental analysis To provide adequate and useful information to federal and state agencies to make permit decisions regarding this proposed project the federal EIS that is ultimately prepared for this project must address and resolve significant regulatory requirements that are specified in the terminal groin law enacted in 2011 by the North Carolina General Assembly This law is being incorporated into the federally approved coastal plan for North Carolina and therefore there is an obligation by all federal agencies to act in a manner consistent with the state s plan as mandated by the Coastal Zone Management Act of 1972 Fortunately the Council of Environmental Quality s (CEQ) guidelines call for detailed descriptions of proposed altematives as well as for a thorough explanation of their refection (CFR 40 § 150214(a -f)) This is further supported by the NCGS § 113AA that defines the information the state agency needs to include in an EIS to satisfy state environmental review requirements Similarly the NCGS § 113 A —115 1 (e)(1) requires the applicant for the permit to submit information to demonstrate that non structural approaches to erosion control including relocation of threatened structures are 1 impractical Under state law no permit for a terminal groin can be issued if nonstructural alternatives are practical and will achieve the projects purpose The applicants stated purpose of the project is to implement an erosion control and beach/dune restoration that will provide long -term protection to residential structures and Town infrastructure along the western end of South Beach The applicant also states the project would be expected to complement existing island wide nourishment activities and is expected to protect town infrastructure roads homes beaches protective dunes and wildlife habitat The project description is troublesome in that the applicant clearly states its preferred alternative before any alternatives have been thoroughly investigated and discussed during the formal EIS process It would seem reasonable to limit the project s purpose as stated in the public notice and vet all alternatives prior to selection of the preferred alternative by the applicant The description of the project purpose in the Corps public notice dated March 14 2012 would provide that overall general purpose of the applicant but it instead takes the leap from that stated purpose to the specific altematve of a terminal groin which would seem to prejudice the project s stated purpose from the beginning Clearly other alternatives must be evaluated and non - structural alternatives may be much more practical once the total benefits and costs of this project are more fully understood Other communities have selected to pursue non - structural alternatives to achieve similar project purposes For example the Town of North Topsail Beach has chosen the option of inlet channel relocation over the one of building a terminal groin Similar inlet channel relocation projects have been permitted in the past at both Mason and Bogue Inlets In addition the applicant also needs to provide detailed information necessary to demonstrate that structures or infrastructures are imminently threatened by erosion [NCGS § 113 A --1151 (e)(1))] According to 15A NCAC 07H 0308 imminently threatened structures are defined as those which foundation septic system or nght -of- way in the case of roads is less than 20 feet away from the erosion scarp The actual number and location of structures that qualify as imminently threatened based upon the rules of the Coastal Resources Commission need to be identified In relation to the latter it is paramount forthe applicant to demonstrate that the construction and maintenance of the terminal groin will not result in significant adverse impacts to private property or to the public recreational beach [NCGS § 113 A — 115 1 (f)(4)] In order to comply with this requirement the applicant needs to identify what constitutes a significant negative impact that must be mitigated as well as what boundaries (and specifically why certain boundaries are chosen over others) the applicant is considering when demonstrating lack of significant adverse impacts NCGS § 113 A — 115 1 (f)(5) also requires the post - project monitoring and necessary mitigation To comply with this the project application must show one crucial component 2 - the definition of thresholds This definition will serve the dual purpose serve as a baseline for determining mitigation of any future adverse impacts and serve as a baseline for future monitoring Shifting baselines a widely accepted term among scientific community is used to describe ways in which significant changes in a system are measured against previous reference points or baselines Failure to identify correct baseline can significantly affect future assessment of not only monitoring of natural systems but also of mitigation of the adverse impacts to the natural system and private property as well The federation suggests that the thresholds be determined based upon the predictions of future shoreline and inlet configurations that are associated with each individual project alternative identified in the EIS In order to demonstrate that non structural alternatives are impractical the EIS must clearly rp ove that a terminal groin will result in more beneficial shoreline and inlet configurations that cost - effectively accomplish the rp oiect Purposes This means the terminal groin alternative must then deliver on what the applican t romises since any future shoreline and inlet configurations that could have been achieved with a non - structural alternative constitute unacceptable Performance by the terminal groin Therefore the thresholds for mitigation of unacceptable impacts caused by the preferred alternative are any actual beach and inlet configurations that could have been achieved by using a non - structural alternative or no action In evaluating the costs and benefits of various project alternatives the applicant should represent scenarios that include the effects of storms on the project area The applicant should compare the effects of storms on the project area with a terminal groin with non- structural alternatives and with no action If the applicant is unable to account for the effects of storms in predicting and comparing project benefits and costs among various alternatives then the state law will make the applicant liable for future damages that result from storms once the terminal groin is constructed In other words if the EIS indicates that the terminal groin will protect property and property -- supposedly protected is later lost during a storm- -that constitutes a project failure unless those losses are not accounted for upfront in the analysis of alternatives According to National Atmospheric and Oceanic Administration and the U S Geological Service recent data show that the coast of North Carolina will likely be affected by more than 60 hurricanes in a 100 -year period it is therefore reasonable to assume that the proposed project will be affected by at least one mayor storm with catastrophic consequences over its projected lifetime (which in the case of terminal groins is 30 years) The CEQ defines those impacts which have catastrophic consequences even if their probability of occurrence is low' as reasonably foreseeable (CFR 40 § 1502 22(b)(4) and hence requires to the applicant to include them in the EIS Therefore the applicant should account for the impacts of storms when drafting the EIS for the proposed project State law requires that the applicant for a terminal groin submit proof of financial assurance (bond escrow account or other financial instrument) that can cover the costs 3 of monitoring and maintenance implementation of mitigation measures and modification and /or removal of the structure as well as of restoration of Rg= and na vats property negatively affected by the structure These exact costs of this bond insurance policy or escrow account need to be determined so they can be factored into the cost/benefit analysis that is done as part of the alternatives analysis Additional project costs that need to be determined include the increased commitment to beach nourishment near the inlet as well as inlet management costs and how the proposed terminal groin will affect the inlet as well as the inlet inner beaches and estuarine ecosystems Also the EIS should detail the costs of preparing the EIS obtaining permits and expected legal proceedings since any permitting around this issue is likely to be challenged through the courts These total costs of the project are necessary to fully evaluate project alternatives and especially to determine if the terminal groin option is practical feasible and cost- effective Below is a list of other information and issues that the EIS should address • The CRC terminal groin report dated March 1 2010 recommended strategies other than hardened structures to protect beaches and manage inlets should always be considered first To comply with state policy investigating non- structural alternatives should be the main objective of this analysis not rationalizing the construction of a terminal groin Non - structural approaches to erosion control include inlet channel relocation beach nourishment relocation of structures and relocation of power water and sewer infrastructure in a manner and location to protect such infrastructure and public health and safety • Jurisdictional 404 wetlands throughout the project area must be identified and mapped This area includes both sides of the inlet Any impacts to jurisdictional wetlands need to be evaluated and compliance with avoidance minimization and mitigation requirements explained for each project alternative • Critical habitat' as defined by the US Fish and Wildlife Service needs to be mapped on both sides of the inlet The effects of the project alternatives need to be evaluated on this habitat There now seems to be a general agreement by some regulators and agencies that some protected species such as the federally listed endangered Piping Plover can adapt to changes in its required habitat and find new places to live" are troublesome to say the least Critical habitats must be identified and protected as much as reasonably possible due to any impacts of proposed beach erosion measures • Structures or infrastructures that are imminently threatened by erosion as defined by 15A NCAC 07H 0308 need to be identified and mapped Imminently threatened structures are defined as those which foundation septic system or right -of -way in the case of roads is less than 20 -feet away from the erosion scarp • A plan for construction and maintenance of the proposed terminal groin and its accompanying beach fill project that is prepared by a professional engineer licensed to practice in North Carolina must be provided as part of the terminal groin option (NCGS § 113 A —115 1(e)(4)) 4 • A plan for the management of the inlet and the estuarine and ocean shorelines immediately adjacent to and under the influence of the inlet must be provided The inlet management plan shall do all of the following relative to the terminal groin alternative and its accompanying beach fill project (NCGS § 113 A — 115 1 (e)(5)) • Describe the post - construction activities that the applicant will undertake to monitor the impacts on coastal resources • Define the baseline for assessing any adverse impacts and the thresholds for when the adverse impacts must be mitigated (These thresholds should correlate with the various alternatives evaluated by the EIS and any performance of the terminal groin alternative that could have been achieved by a non - structural alternative should be identified as an adverse impact,") • Identify mitigation measures to be implemented if adverse impacts reach the thresholds defined above and state the costs of these mitigation measures • Provide for modification or removal of the terminal groin if the adverse impacts cannot be mitigated and the costs for these modifications and removal • Under each possible project alternative identify those property owners and local governments on both sides of the inlet that may be affected • Identify funding sources necessary to fund the terminal groin and beach fill alternative (including the costs of developing this EIS and obtaining permits) over its design life given that no state funds are available for these projects and local funds spent on these projects by a local government need voter approval No permits for Terminal groins can be issued in North Carolina where funds are generated from any of the following financing mechanisms and would be used for any activity related to the terminal g=orLts accompanying beach fill ro ect (NCGS § 113 A — 115 1 (h)) • Special obligation bonds issued pursuant to Chapter 1591 of the General Statutes • Nonvoted general obligation bonds issued pursuant to G S 1590148 • Financing contracts entered into under G S 160A -20 or G S 159 -148 • The applicant must provide cost estimates for the required financial assurances specified by state law for a terminal groin project These assurances must be in the form of a bond insurance policy escrow account or other financial instrument that is adequate to cover the cost of • Removal of the terminal groin and restoration of the beach if it is determined by an independent third party that the groin has an adverse impact on the environment or on other properties and • Removal of the terminal groin and restoration of the beach if it is determined that the groin has an adverse impact on the environment or on other properties and on the federal navigation channel and • Long -term maintenance of the terminal groin including the cost of any required mitigation measures and compliance with all conditions of the permit and variance E • Detailed information about storm impact and effects upon the terminal groin and also on the inlet dynamics and morphology the beach profile sand resources residential structures private property adjacent properties and the natural resources and environment of the permit area due to the placement of the terminal groin • Detailed information and modeling on the impacts of sea level rise on the terminal groin and the resulting effects upon inlet dynamics adjacent property beach profiles residential structures and the natural resources and environment of the island and adjacent islands and estuarine habitats and resources • The development of accurate cost- benefit analysis to ensure the costs of storm events is appropriately considered and modeled using real world and real time property appraisals for all project alternatives The high risk of significant storm damage to beach front properties should be part of the cost - benefit analysis and used to discount the project benefits for each possible alternative considered • The economic costs and benefits of each project alternative should include the positive economic values associated with natural inlet processes (fishing tourism habitat creation and larvae transport and fish migration) • Detailed study and modeling of the effect of any proposed terminal groin on the inlet dynamics which increase the frequency of needed dredging and could have long -term negative impacts upon the structure itself and on adjacent shorelines both east and west of the groin The effect of the groin on inlet narrowing and loss of natural inlet shoals and sand flats should be investigated as well at the possible increase in tidal flow due to inlet morphology changes • Thorough modeling of the effects of the terminal groin on the ebb shoal deflation should be considered along with both the economic and resource related costs This loss of sediment volume could steepen the near shore beach profiles and in turn increase the wave energy reaching the coast and inner inlet areas • Thorough modeling of the effects of the terminal groin on the navigation channel and the effects of the continued required navigation channel maintenance and dredging on the integrity of the terminal groin itself and its proposed functions and purported benefits • Incorporation of the state Beach and Inlet Management plan into the EIS process and consideration of those recommendations for avoidance of hardened structures on the beach • Consideration of the proposed terminal groin and its possible effects of reducing the long shore transport of sediment to the area identified as West Beach and how that reduction of sediment will affect erosion or accretion at that location as and that potential effect upon the areas natural resources and public and private infrastructure • Identification of the purpose and need to keep the e)asting permitted sand filled tube groins in addition to the construction of a terminal groin as proposed Detailed analysis of the success or failure of the permitted sand groins and detailed modeling of the effects of the terminal groin with the sand groins removed and kept upon the affected areas and requested terminal groin • Consideration of the proposed terminal groin and its possible effect upon the east end of Oak Island the historic sites public and private property Detailed 1.1 modeling should be required to review the possible effects of the proposed groin upon the federal navigation project and detailed modeling and monitoring of any impacts upon that public project as a result of a terminal groin • The effects of the terminal groin on the critical piping plover habitat on each side of the inlet must be evaluated How the project will comply with the Endangered Species Act must be addressed • The potential effects of the terminal groin upon the dust listed Atlantic Sturgeon on the federal Endangered Species Act and upon the Short Eared Sturgeon Eastern Manatee and other endangered marine life that utilize the Cape Fear River and inlet channel in their life cycle • The effects of the terminal groin upon endangered sea turtle habitat on both Bald Head Beaches and beaches at Oak Island should be thoroughly researched and analyzed -The potential effects of the design of the proposed terminal groin as a leaky" structure should be researched and analyzed and how any injury or death will be avoided due to the leaky structure design from trapping sea turtles and other critical manne and mammals within the groin itself • - How will both adult and hatching sea turtles survive storm and wave action in and around the terminal groin? • The proposed terminal groin is described as a leaky structure Detailed description of that structure should include it s leakage rate and how that will affect the required beach nourishment and identify milestones that should be established to address the groin s leakage rate How will this leakage rate affect the use of the public beach and its affect upon the natural resources of the beach community? How will the leakage rate affect erosion or accretion on the West Beach area and how will that leakage rate be calculated • Consideration of the gradual blockage of the leaky" groin due to growth of marine life debris and other impediments and what measures and strategies will be designed to address this possibility • The potential effects of the gran upon the Cape Fear River inlet system tidal flow and fish migration should be investigated as well as the effects upon Jaybird shoals and essential fish habitat identified in the inlet system • Proof and analysis that a terminal groin will reduce the frequency of required beach nourishment and address how the proposed leaky structure will affect that required frequency • A terminal groin could negatively affect an inlet s equilibrium and its ability to maintain a sediment balance This could result in more manipulation of the inlet and associated costs to the overall long -term project These long -term management costs need to be determined and factored into the alternatives analysis • One option that is not addressed in the proposal is to augment or enhance and improve the current permitted sand filled tubes to address the erosion issues and perform a detailed analysis of the sand filled tube groin field success and how those permitted structures could be revised to fulfill the projects stated purpose • If the permitted sand filled groin field is allowed to remain and a terminal groin is permitted will that violate the intent and language of Senate Bill 110*7 According 7 to the approved legislation only one terminal groin will be permitted at the end of a bamer island The 16 sand filled groins if left on the public beach might violate the intent and spirit of the approved legislation A legal opinion of this issue should be considered by the state and the Coastal Resources Commission The Federation has serious concerns about the proposed terminal groin project at Bald Head Island A careful analysis of alternatives that are evaluated based upon the requirements established by the NC General Assembly are likely to show that non- structural alternatives are more cost- effective and practical The Corps must ensure that the EIS addresses these explicit state mandates since they are part of the state s coastal management requirements and program We appreciate the opportunity to comment and be involved in this project Please do not hesitate to contact us if you have any questions of need any clanfication of these preliminary comments We intend to fully participate in the development of this EIS the review of project permits and any court proceedings that might follow With best Mike'Giles Ana Zivanovic- Nenadovic Coastal Advocate Program and Policy Analyst
