RE: NC CAMA Permit Application —Major Modification Request to State Permit No. 91-14
Village of Bald Head Island Frying Pan Shoals Beach Nourishment Project
Response to Request for Additional Information
Dear Heather:
By way of this letter and on behalf of the Village of Bald Head Island (Applicant), Land Management
Group (LMG) (agent) is providing the following response to your request for additional information
(RAI) dated June 26, 2020 for the Major Modification application for State Permit No. 91-14. The
RAI pertained to comments received from the North Carolina Division of Marine Fisheries (DMF) by
way of their letter dated June 2, 2020. Additional comments were received from the NC Wildlife
Resources Commission (WRC), the NC Division of Water Resources (DWR), and the State Historic
Preservation Office (SHPO). Responses to these comments are provided below (with supporting
attachments where applicable and referenced).
I. NC Division of Marine Fisheries Comment and Response
Comment #1: DMF requests that an Environmental Impact Statement (EISJ be prepared through the
USACE.
Response: The Village of Bald Head Island previously as Applicant requested and participated in a
project scoping meeting (conducted on October 2, 2019) at the NCDEQ Wilmington Regional Office
to present the proposed action and to discuss the appropriate process for evaluating the
application for a permit decision. The lead state and federal permitting agencies determined that a
request to modify the Terminal Groin Individual Permit (Department of Army Permit No. SAW-2012-
00040) and the CAMA Major Permit (91-14) was the appropriate process for a permit decision. The
USACE determined that an EIS is not required for this modification request. This decision was based
largely on the EIS prepared for the original terminal groin permit which evaluated the use of several
candidate borrow sites including the use of a borrow site on Frying Pan Shoals. In addition, an
impact assessment for fishery resources is being performed as part of the updated Essential Fish
Habitat (EFH) document to be submitted under separate cover.

Comment #2: Assess impacts to larval transport -Dredging in Frying Pan Shoals can potentially
interfere with the passage of larvae and early juveniles from offshore spawning grounds into
estuarine nursery areas. A detailed scientific field investigation, analysis, and modelling of larval
transport dynamics that exist around Frying Pan Shoals currently and how that will change based on
the proposed dredging activity. This information should be used to model estimated impacts of the
dredging to larval ingress and egress through the inlet.
Response: We respectfully disagree with your assessment for the potential of the dredging project
to interrupt larvae and juvenile recruitment into the Cape Fear River estuary. Hydrodynamic
modeling performed by Olsen for the project EIS (2014) predicted that there is no inlet -directed
tidal flow on either peak ebb or peak flood conditions at Frying Pan Shoals. Therefore, there is no
expected effect on the entrainment of larvae from the proposed borrow site by tidal action. The
request for detailed scientific investigations of larval transport, analysis, and modeling would
require amulti-year research project to be able to provide meaningful data that can control for
inter -year variability. The need for such is doubtful considering that the presence of a borrow site
at this location is unlikely to disrupt larval transport in any significant manner. If there is research
or data in the literature indicating this phenomenon has occurred for other borrow sites, then we
would respectfully request that this information or literature be shared with the Applicant so that it
can be evaluated for its applicability to the proposed project.
Given the size of the proposed borrow site relative to the large shoal feature (less than 0.5%) and
the predicted physical recovery of the borrow area (as described further in response to Comment
#3 below), it can be reasonably expected that the proposed action will not induce any large-scale
disruption to circulation patterns. In addition, the excavated area will tie into natural bottom
contours on the western edge of the shoal feature (i.e. there will not be a hole that could
theoretically entrap or slow larvae). Rather, it is likely that vertical mixing and upwelling patterns
would continue to be maintained with only limited, localized effects to currents/circulation. As a
result, there is not expected to be an effect on the transport of larvae. Lastly, any assumed impacts
to circulation (or disruption to upwelling) is unlikely to affect larval transport given that larvae have
been demonstrated to exert considerable control over vertical movement within the water column
(Morgan and Anastasia, 2008). Larvae and early juveniles are not passive in their movement.
Migration of larvae outside the tidal influence of the estuary is influenced through wind -driven
transport and directed vertical movement by larvae to maximize shoreward movement (Boehlert
and Mundy, 1988). Once nearshore, then alongshore drift is the principal mechanism until larvae
reach the entrainment influence of the estuary. Larvae are adapted to highly dynamic physical
conditions in nearshore environments. Based upon the lack of any significant effects to circulation
patterns, the uninterrupted wind -driven transport of larvae, the ability of larvae to exert control
over vertical movement, and the large entrainment field of the Cape Fear River estuary; larval
transport into the estuary will not be adversely affected.
Comment #3: Assess sediment transport and refilling of borrow area -The proposal to dredge a
hole, nearly 20 feet deep in some locations, in the shoal could negatively and potentially
permanently alter the habitat on the shoal. Frying Pan Shoal is classified as a relict shoal receiving
much of its sand deposits from the Holocene and Pleistocene periods (Normandeau Associates, Inc.
2014). These shoals formed over a long period of time and may not recover at rates necessary to

Page �3
sustain recurring borrow activities. It is unknown how currents, wind, and storm events will respond
spatially and temporally to removal of sand from the shoal. In addition, no studies have been
performed to investigate the type of material that is expected to be deposited within the footprint of
the excavated area. If incompatible materials fill the dredged footprint, new borrow sources will be
sited on the shoal resulting in cumulative impacts to the habitat. A sediment transport model should
be used to investigate the previously mentioned concerns.
Response: The proposed excavation will tie into natural bottom contours along the western edge
or flank of the shoal feature. As a result, there will not be a "hole" within the shoal crest. The
dredge contours are designed such to induce greater rates of recharge with characteristic sand -
grained sediments transported over the shoal. It is highly unlikely that there will be any fine-
grained deposition post -dredging due to the ambient sediment characteristics and dynamic physical
conditions of the borrow site. This is supported by observations by McNinch (2009) who
commented, "Sediment dredged from the northwest flank of FPS will likely recharge episodically
from sediment transported from the crest during storms, particularly extratropical nor'easters".
The post -excavation substrate is expected to be self -similar to the existing condition (prior to
dredging). The project as designed ensures that the depth of excavation is strategically limited such
that the sediment exposed (post -dredging) has similar granular characteristics to the native seabed.
In addition, the location and the design promotes rapid and continuous material transport into the
excavated area.
With respect to the predicted rate of sediment transport, McNinch (2009) observed the following:
"The most active region of sediment recharge to FPS is likely near the cape point, particularly
along the crest of the shoal where it extends seaward from the subaerial cape point and the
shore parallel sand bar that merges into FPS from the updrift beach". (Note —the updrift
beach or shoreline northward of the cape point is known as East Beach on BHI).
Numerous individuals or organizations have performed estimates of littoral transport along the
every -varying shoreline components of the State of N.C. More recently, (Van Gaalen, Tebbens and
Barton, 2016) have summarized sediment transport directions from Northern Maine to Tampa Bay,
FL. For the Cape Fear formation, the published rates for the two Bald Head Island shorelines that
join to form the Cape Fear Point are as follows:
• South Beach — 339,300 cubic meters annually toward the East.
• East Beach — 341,000 cubic meters annually southward.
This represents a potential net annual hypothetical rate of deposition to the Cape Fear Shoal
formation of 680,300 cubic meters (i.e. 813,215 cy). Annual monitoring of South Beach indicates
that net easterly transport would typically be less than that estimated above. For more information
regarding sediment substrate, predicted recovery, and factors influencing borrow site selection and
design, please see attached discussion prepared by Olsen Associates, Inc. (Attachment A).

Comment #4: DMF would also like to see the applicant explore alternative sand sources that may
have less significant impacts to critical fisheries habitats; this would include previously permitted
alternative borrow sources.
Response: The Applicant understands and appreciates the need to explore and utilize the least
environmentally damaging, practicable alternative (LEDPA) sand source site. A robust alternatives
analysis of potential borrow sites was performed as part of the permit application. The only other
viable site identified (of sufficient size, containing beach -quality sand, and being operationally
feasible) was Jay Bird Shoals (1BS). Indeed, from a logistics standpoint there is preference to utilize
the previously authorized and dredged JBS site. That being said, the Village utilized this site for a
second time in its most recent Village -sponsored nourishment project (occurring in Winter
2018/2019), and Oak Island recently received authorization to dredge an approximate 304-acre
borrow site located within JBS as part of a 1.1Mcy nourishment project to be implemented this
coming winter (Winter 2020/21). As a result, the JBS sand resource will be depleted for the
foreseeable future. However, the borrow site is continuing to be physically monitored on an annual
basis. If the shoreline of South Beach can be maintained though federal nourishment for a period
of time and sufficient physical recovery occurs within JBS prior to the next nourishment need, then
the Village will seek to utilize JBS as an alternative sand source site prior to the use of FPS. Physical
monitoring of the JBS borrow site will determine the volume of sand available for dredging prior to
the next Village -sponsored nourishment, and this information will be provided to the agencies to
determine if JBS can be utilized in lieu of FPS.
The use of Bald Head Shoals seaward of the Point and western South Beach is not viable. Its
proximity to this highly erosive section of shoreline adjacent to the federal navigation channel
renders its use impracticable and counterproductive as it affords that portion of beach much
needed protection through wave and current attenuation. Use of this shoal as a sand source site
would result in the need for increased frequency of nourishment events, a condition not deemed
environmentally favorable nor operationally and financially practicable. It can therefore be
excluded from consideration as the LEDPA.
Comment #5: Comments related to ecological effects of dredging within Frying Pan Shoals.
Response: The Applicant will be submitting an updated Essential Fish Habitat (EFH) document with
a more thorough impact assessment describing potential ecological effects to EFH habitat and
managed species. A copy of this report will be submitted to both the NC DCM and NC DMF. A brief
description of avoidance and minimization measures are provided below. In addition, attributes of
the borrow site location and design that help to minimize ecological effects are outlined in
Attachment A. The Applicant and project engineer have worked to reduce the limits of spatial
impacts of the proposed borrow site based upon comments received subsequent to the submittal
of the 2016 proposal. Of particular note with respect to avoidance and minimization efforts since
the 2016 submittal is the following: the deletion of the dredge access corridor (aka "fairway"); the
reduction in borrow site acreage (from 460.1 acres to 198.4 acres); and the limitation of dredging to
an initial single borrow event to be monitored.

Page �5
The project as designed will incorporate the following protection measures identified by the South
Atlantic Fisheries Management Council (SAFMC) specific for dredge and fill projects in areas
designated as Habitat Areas of Particular Concern (HAPC). These include the following:
1. Impact assessment (description of potential impacts; baseline information; alternatives
analysis; construction monitoring; post -construction monitoring plan);
2. Fill material should match that of recipient beach as closely as possible;
3. Dredging to be located in areas characterized by strong currents and sand movement to
promote more rapid infilling rates (and thus reducing the duration of impacts to benthic
habitats); and
4. Dredging should be performed in a manner intended to minimize impacts to wave energy
and currents, "thus reducing the likelihood of infilling with fine-grained sediments".
In addition to the SAFMC protection measures, the proposed project incorporates following design
elements that helps to further reduce or avoid impacts to natural resources:
1. The site is a highly dynamic and renewable shoal feature (maintained by seaward flow of
current off cape) and thus physical and biological disturbances tend to be short-lived;
2. The position of borrow site on the western flank represents a sediment sink (thus promoting
rapid recovery and infilling with like material);
3. The combination of size and position of sand source site results in least impacts to shoal
integrity;
4. Dredging to occur during winter months (reduced biological activity);
5. The project will allow for undredged areas in close proximity to be left undisturbed to
promote more rapid recolonization of benthos (as was documented for Jay Bird Shoals and
Bald Head Creek Shoals with similar post -project conditions);
6. The project will avoid hard -bottom habitat;
7. The project will avoid Primary Nursery Area (PNA) impacts;
8. The project will avoid inlet and associated shoals for large-scale sand volume needsl;
9. The project will utilize hydraulic cutter suction dredge (thereby avoiding and minimizing
physical entrainment of species in close proximity to the dredge operation); and
10. The project will include post -project physical monitoring of borrow site (i.e. assessment of
physical recovery).
The proposed action is not anticipated to have any long-term effects on fishery species. This is due
in part to the following considerations: (1) the limited spatial and temporal effects of elevated
turbidity due to high sand content of dredged sediments and rapid dilution; (2) the mobility of
finfish and associated avoidance behavior; (3) the physical conditions of the dredge site favoring
rapid infilling and benthic recovery; (4) avoidance of peak benthic and larval fish recruitment
periods during dredging and nourishment; (5) fecundity and opportunistic nature of benthic
communities to accommodate anthropogenic and natural disturbance; and (6) the avoidance and
minimization measures described above.
Given the size of the proposed borrow area relative to the FPS feature (less than 0.5 %spatially and
0.1% volumetrically) and the annual rates of sediment input, the morphological integrity of the

shoal will not be affected by the proposed action. Provided the overall physical integrity of the
shoals is maintained, then potential adverse effects to ecological functions are minimized. In
general, it is preferable to utilize sites that are anticipated to have a high likelihood of physical
recovery and biological recovery. The location of the borrow site on the western flank of FPS
ensures infilling with sand (consistent with the existing substrate) and a relatively high rate of
recharge.
In light of the favorable physical conditions of the borrow site (suitable substrate and characteristics
favorable for physical and biological recovery), avoidance of other sensitive EFH habitats, adherence
to the identified SAFMC protection measures, and incorporation of additional mitigative actions, it
is believed that potential adverse ecological effects are minimized.
Comment #6: There are numerous questions remaining that need to be addressed before this
project should go forward. Staff from BOEM are currently planning to hold a workshop this fall to
discuss the state of the science of Frying Pan Shoals and how to move forward in addressing data
gaps. Until then, the applicant has a viable alternative, use of Jay Bird Shoals. The NCDMF therefore
objects to this permit modification request. Should the project be permitted, the NCDMF requests
that the applicant be required to monitor sediment deposition rates and composition, as well as
monitor benthic invertebrate composition and change to productivity. The project should be
considered aone-time event until all necessary research recommended by NCDMF and the 2020
BOEM workshop is completed and reviewed.
Response: The Applicant's consultant (LMG) will be attending the BOEM workshop this Fall.
Contemplation of any sand source sites in federal waters (as BOEM is evaluating) would require the
use of a hopper dredge and work during environmental moratoriums. As a result, potential
ecological effects of such would be significantly greater.
With respect to the use of Jay Bird Shoals (JBS), as referenced above, due to both the recent Village -
sponsored dredging of JBS and the recent authorization issued to the Town of Oak Island (Action ID
Number SAW-2018-02230) to dredge 1.1 Mcy of sand from JBS this coming year (2021), the use of
JBS for additional sand nourishment needs is not possible at this time or in the near future. That
being said, the Applicant will seek to preferentially utilize JBS should the sand source site
demonstrate sufficient physical recovery and sufficient volumes of beach -compatible sand prior to
the need for the next locally -sponsored nourishment of South Beach.
Note also that this Major Modification request is for aone-time dredge event with both physical
and benthic monitoring proposed to evaluate the effects of dredging on FPS prior to any requests
for dredging in the future. The Applicant acknowledges the need for the monitoring of
physiographic, sedimentary and benthic recovery within the proposed area of excavation. VHBI's
engineer (Olsen Associates) believes that based upon the existing precepts of the Wilmington
Harbor Sand Management Plan, which episodically places high quality maintenance sand on BHI, it
could be necessary to construct an interim locally sponsored beach fill project on 8- to 12-year
intervals (more or less). However, the use of JBS for future events could very well provide a viable
alternate sand source in lieu of the FPS borrow area.

II. NC Wildlife Resources Commission Comment and Response
Comment #1: Request modeling of sediment transport for determining recovery/recharge.
Response: Refer to response to NC DMF Comment #3 above. There have been a number of
investigations studying sediment transport along the North Carolina shoreline. The published rates
for the two Bald Head Island shorelines which join to form the Cape Fear Point are as follows:
• South Beach — 339,300 cubic meters annually toward the East.
• East Beach — 341,000 cubic meters annually southward.
This represents a potential net annual hypothetical rate of deposition to the Cape Fear Shoal
formation of 680,300 cubic meters (i.e. 813,215 cy). Annual monitoring of South Beach by the VBHI
indicates that net easterly transport would typically be less than that estimated above.
Comment #2: Concern regarding cumulative effects of multi -dredge event project.
Response: The Applicant is requesting aone-time dredge event under this Major Modification
request for a borrow site area that has been substantially reduced from the prior 2016 request. The
Applicant and project engineer have worked to reduce the limits of spatial impacts of the proposed
borrow site based upon comments received subsequent to the submittal of the 2016 proposal. Of
particular note with respect to avoidance and minimization efforts since the 2016 submittal is the
following: the deletion of the dredge access corridor (aka "fairway'); the reduction in borrow site
acreage (from 460.1 acres to 198.4 acres); and the limitation of dredging to an initial single borrow
event to be monitored.
Post -dredge monitoring of physiographic, sedimentary and benthic parameters will be performed
to accurately assess the recovery of the borrow site. These data will be evaluated and used for any
potential consideration of future dredge events. Note that Olsen Associates believes that based
upon the existing precepts of the Wilmington Harbor Sand Management Plan, which episodically
places high quality maintenance sand on BHI, it could be necessary to construct an interim locally
sponsored beach fill project every 8 to 12 years (more or less). However, the use of Jay Bird Shoals
(JBS) for future events could very well provide a viable alternate sand source in lieu of the FPS
borrow area. As a result, the potential for any long-term cumulative effects is significantly reduced
or avoided.
Comment #3: Adherence to applicable environmental windows.
Response: The proposed modification requests to perform the work during the acceptable
environmental windows and will avoid shorebird and sea turtle nesting periods (combined April 1 to
November 15 moratorium). If there is any proposed deviation to the planned dredge and
nourishment work window, the Applicant will coordinate with state and federal permitting and
resource agencies for appropriate authorization.

Comment #4: Survey and monitoring reports.
Response: The Applicant has performed post -construction monitoring of the terminal groin project
with reports submitted on an annual basis to the Corps of Engineers.
Comment #5: Concern over repeated beach nourishment projects (higher frequency intervals).
Response: Noted. Prior macro -invertebrate monitoring of the beachfront both pre- and post -
nourishment (conducted along South Beach and West Beach from 2009 to 2012) revealed that
macroinvertebrate taxa fluctuate seasonally. For coquina clams, no statistically significant
differences were found between pre -construction and post -construction conditions. For mole crabs
and ghost crab burrow hole densities, some significant differences between pre- and post -
construction sampling events were identified. However, the statistical (ANOVA) analysis revealed
that these fluctuations were likely due to seasonality and other factors not measured in the study
rather than project -related activities (since similar differences were observed within control sites).
Numerous studies have demonstrated rapid recovery of invertebrate taxa along nourished
shorelines (less than one year) provided that the fill material is beach quality sand and similar in
texture and composition to the recipient beach (Hackney et al. 1996, Nelson 1993, USACE 2001).
Comment #6: Concern regarding beach profile slope (i.e. need to avoid backslope or trough in profile
that could trap or disorient nesting sea turtles or hatchings).
Response: Noted. The design avoids backsloping of beach profiles. Construction management will
include monitoring of the profile to ensure that backslopes or troughs do not occur.
Comment #7: Dune revegetation and stabilization should follow resource agency guidelines.
Response: Noted. The Applicant will consult with appropriate agencies to implement appropriate
methods for dune revegetation and stabilization. Every attempt will be made to complete the dune
stabilization measures during the applicable environmental windows.
Comment #8: Recommend overview of beach management activities occurring on the Island and
the preparation of a single comprehensive management plan.
Response: Noted. The project EIS discussed all recent and proposed dredge and beach
nourishment projects (for the reasonably foreseeable future). Beach nourishment actions
implemented by the Village are also a matter of permit record. A copy of the engineered beach
plan outlining beach management activities for the Island is also provided for reference
(Attachment B).

III. NC Division of Water Resources Comment and Response
Comment: Please provide more details that addresses the concerns from the NCDMF and the
NCWRC regarding practical alternatives and avoidance and minimization of impacts for this project.
(15A NCAC 02H .0506(fJ and (gJ] If these issues are not resolved, the NCDWR will have to move to
deny your application as required by 15A NCAC 2H .0506. If these concerns are addressed to the
satisfaction of the NCDMF and the NCWRC, the NCDWR will have no objection.
Response: Noted. The Applicant is providing responses and additional information to the
commenting agencies (namely NC DMF and NC WRC). There have been a number of additional
avoidance and minimization measures identified (to be implemented) since the prior 2017 permit
modification request. Principally among these measures have been the reduction of the extent of
the dredge footprint and confining this modification request to a one-time dredge event to be
monitored for the assessment of physical and biological recovery (as described in more detail
above). In addition, the Applicant agrees to prioritize the use of Jay Bird Shoals should adequate
recovery of that sand source be demonstrated prior to the need for the next Village -sponsored
nourishment. Lastly, the project is to employ the protection measures identified by the South
Atlantic Fisheries Management Council (SAFMC) specific for dredge and fill projects in areas
designated as Habitat Areas of Particular Concern (HAPC) as well as several other measures
identified in the responses provided above. As a result, it is the position of the Applicant that the
proposed project will not result in a significant impact to EFH (as has been demonstrated for other
dredging projects routinely occurring within EFH and HAPC of North Carolina state waters) and
therefore does not represent a degradation of state waters.
IV. State Historic Preservation Office (SHPOI Comment and Response
Comment: The Bald Head Island south beach renourishment project has the potential to affect
culturally significant shipwrecks, if avoidance protocols are not enacted. Avoidance is essential given
the potential of irreparable damage to cultural resources, as well as to the dredging equipment, as
site CF1001 -the Ella is a substantial steel structure. We are aware however that work has been
carried out in the area in the past, with the dredging of the channel and the installation of stone
jetties (sic). We, therefore, concur with the recommendation outlined in the submitted report from
2016, which states "In the event that the buffered anomalies can be avoided, no additional
investigation is recommended in conjunction with the proposed project." To that effect, we offer this
"unanticipated discoveries" condition:
If additional cultural resources) are identified during monitoring and/or construction, all work will be
halted within the limits of the resource(sJ and the Office of State Archaeology (OSA) will be contacted.
Work should move to another area and the Underwater Archaeology Branch should be contacted
immediately (910-250-7320J. A staff member will be sent to assess the wreckage and determine the
proper course of action.
The OSA will initiate the coordination required for a determination of eligibility or recovery effort. If
after consultation between the County and OSA, additional mitigation is determined necessary, the
County, in consultation with OSA, will develop and implement appropriate protection/mitigation

>aaC>��Rouly�
The Cape Fear Shoals {FPS) formation has been evaluated as a potential sand source far
purposes of beach restoration beginning in the 1970's (Meisburger, 1977). That Reconnaissance
level work was carried out by the Coastal Engineering Research Center (CERC} far the
Wilmington District, USACOE. Both cores and sub -bottom survey comprised the ma�arity of
the data acquisition performed for purposes of defining the spatial distribution of potential sand
sources located within FPS. At the time, isopachs of potential sand thickness indicated at least
1.4 billion cubic yards of potential beach quality sand located within the Cape Fear Shoals
formation. This estimate is assumed to be conservative.
McNinch (2449) performed a Literature Review r�,f Cuspate Forelands which included a
discussion of the implications of dredging Frying Pan Shoals. With respect to the latter, Dr.
McNinch made the following observations which are relevant to the siting of the proposed VBHI
borrow site;
* "The most active region of sediment recharge to FFS is likely near the cape point,
particularly along the crest of the shoal where it extends seaward from the subaerial cape
point and the shore parallel sand bar that merges into FPS from the updrift beach". Note
-� the updrift beach or shoreline northward of the cape point is known as East Beach on
I�HI.
+ Sediment along the flanks of FPS likely migrate crestward during swell conditions and
seaward when it reaches the crest".
iaThe crest of the shoal is likely planed -off during storm canditlans, when waves are steep
and breaking occurs across the shoal, and sediment is transported to the flanks".
Judy, zo2o i �Isen associates, inc.

• "Sediment dredged from the northwest flank of FPS will likely recharge episodically
from sediment transported from the crest during storms, particularly extratrapical
nor' eastern".
Numerous individuals ar organizations have performed estimates of littoral transport
along the every -varying shoreline components of the State of N.C. Mare recently, (Van Gaalen,
Tebbens and Barton, 2016) have summarized sediment transport directions from Northern Maine
to Tannpa Bay, FL, For the Cape k'ear fannatian, the published rates far the two BHI shorelines
which join to farm the Cape Fear Paint (see Figure 1}are as follows:
* South Beach — 339,300 cubic meters annually toward the East,
• East Beach — 341,000 cubic meters annually southward.
Thin represents a potential net annual hypothetical rate of deposition to the Caps Dear
Shoal formation of 680,300 cubic meters {i.e. 813,215 cy). Note —annual monitoring of S.
Beach indicates that net easterly transport would typically be less than that estimated alaave,
In 2009, the Wilmington District, USAGE acquired some 31 Vibracores in proximity to
the western side of Frying Pan Shoals as part of a sand search far the Brunswick County Share
Protection Project. The Tistrict then contracted with Catlin Engineers and Scientists of
Wilmington, N,C. to analyze the cores. A summary of findings was provided to the Wilmington
District an 27 May 2010 (Catlin, 2010). The report included core lags, grain size classi�icatians
and various summaries of the sediment characteristics encountered suitable far beach rentaration.
In 2016, Olsen Associates, Inc, initiated amulti-phase Sand Search Investigation of
Frying Pan Shoals (Olsen, 2U16) intended to allow for the permitting, of a barrow site within
State waters.
July, 2020 z �Isen associates, ir�c.

The chronological Task Logic for the phased Sand Search sponsored by the VBHI can be
summarized as follows:
l . A coarse grid survey was performed to update general bathymetric shoal features within
the 3-mile limit. Mapping utilizing federal NpS data was got reliable for purposes of
coring.
2. A Phase I (coarse grid) Cultural Resource Investigations was carried out to eliminate any
dense clustexs of magnetic anomalies which would indicate a high probability of a ship
wreck site. It was determined that no level of geatechnical investigation would be
performed in any such areas identified.
3. Based upon 1.) and 2.) above, a Vibracoring Plan was formulated so as to maximize
potential depths of beach compatible sediment, with the intent of minimizing future
conflicts with probable cultural resource locations.
4. Subsequent to coring, asub-bottom survey was performed to extend the data base
between cores and to areas of interest where cores would not be feasibly (or safely)
acquired due to shallow depths, breaking waves, or tidal surging,
S. In consideration of the results of the seismic survey, Vibracore logging and laboratory
analyses of sediment samples aver depth, a generalized borrow area was def ned by
Olsen Associates, Inc. —all of which is dacum,ented in a comprehensive report {�lsen,
201 &).
6. Subsequently, a Fhase II Cultural Resource Investigation was performed of the selected
barrow area in order to eliminate areas of avoidance recommended by the project marine
archaeologist. The final Permit Application was based upon the refined borrow site
limits which included buffers between, or around unverified anomalies and future
dredging activities.

l3�Rlt[�W SYTI� SELECTYUN
The selection of the proposed 188.7 A. area borrow site was determined on the basis of
both environn�tental and physical characteristics, Although the engineering design of the
proposed barrow site is a matter of record {Qlsen, 2016}, in order to minimize environmental
impacts, the following relevant selection parameters were prioritized:
� Burrow Site Recovery — As recommended by McNinch (2a09), the proposed area of
excavation is principally located on the crest of the existing shoal formations which is the
most high energy i.e. dynamic} portion of the shoal. This will assure rapid pnst-
constructian deposition of new material into the excavated area. AIthaugh it is not
possible to reliably "numerically model°'the infilling process due to the complexity of the
shoals ever changing bathymetry, it can be reliably estimated based upon the anticipated
volume of material which episodically enters the shoal forrriation from the two (2}
shorelines an BI�I which farm the Cape Foint. A conservative engineering estimate of
the ability of the FPS borrow area to recover SO-90% of the neat volume removed is 1Q
years, or less.
• Barrow Site Substrate —For purposes of rapid benthic recovery, the post -excavation
substrate should be self=similar to existing prior to dredging, This is addressed two ways:
a) by ensuring #hat the depth of excavation is strategically limited such that the sediment
exposed (post -dredging) has similar granular characteristics to the native seabed, and b.}
by ensuring that material transport into the excavated area will be rapid and continuous.
Under such constraints, benthic recovery of the "disturbed" seabed typically occurs
within 1-year.
• Minimization of the Area ]rrpacted —Far purposes of reducing temporal dredging
impacts to pre-existing benthic resources, it is desirable to design a borrow area having
the smallest effective "fast print". k`ar this site, this is accomplished principally through
the utilize#ion of a cutter suction dredge, as well as the 5peci�cation of a dredged area
with the thickest layer of sediment available =which far the FFS formation is
synonyrnaus with the centralized portion of the shoal. Although the depth of excavation
July, 2020 4 QISEn c]55oCiSt�S, inc.

at that location may exceed 15 ft. below the seabed, it is reliably predicted that shoal
dynamics at this location will quickly reduce the effective borrow depth due to rapid
infilling and slope adjustments. Note — A secondary benefit of a cutter suction dredge is
that it does not "entrain" fishery resources � in contrast to a hopper dredge which
represents a quantifiable threat to fishery resources during the dredging process including
etadangered species such as the Atlantic Sturgeon.
* Frequency of Occurrence =The Applicant's consultant has opined that based upon the
existing precepts of the Wilmington Harbor Sand Management Plan, which episodically
place high quality maintenance sand on BHI, it could be necessary to construct an interim
locally sponsored beach fill project every 8-12 years, mot. It is acknowledged however,
that subsequent to the first use of the FPS borrow site, it could be possible that the
Agency preferred borrow area located at Jay Bird Shoals may have sufficiently recovered
by that time. As such, it could provide a viable alternate sand source in lieu of the F1'S
borrow area.
• Confirmation of Impact and l�ecvvery Predictions � The VBHI as Applicant for the
development of the FFS borrow site acknowledges the need for the monitoring of
physiographic, sedimentary and benthic recovery within the proposed area afexcavation.

PREFACE
In February 2009, Olsen Associates, Inc. issued a documentation report entitled "Village
of Bald Head Island, Engineered Beach Project". The following report (dated September 2018)
serves to update the earlier report in anticipation of the predicted impacts associated with
Hurricane Florence to the North Carolina coastline and more specifically to Bald Head Island.
It is noted that during the period 25 August to 1 September 2011, Hurricane Irene caused
impact to Bald Head Island's "engineered beach" project. In accordance with FEMA
Declaration No. 4019 DR NC, Project Worksheet (PW) BHGJS03 allowed for Category `G'
sand placement along a portion of South Beach impacted by the event. Subsequently PW No.
BHGJS0300588 was issued for the replacement of five (5) damaged sand tube groins.

DOCUMENTATION FOR THE
VILLAGE OF BALD HEAD ISLAND, NC
ENGINEERED BEACH PROJECT
PURPOSE
In 1998, the Village of Bald Head Island formally embarked on a long-term Plan for
Island -wide Beach Management. Simplistically, the goal was to develop an "engineered"
solution to beach erosion along South Beach and portions of West Beach, both of which are
physically interrelated through a common littoral sand sharing system. At the present time the
program of improvement is based upon three (3) major components:
a) Large scale beach restoration through sand placement volumes sufficient to create
and maintain natural beach widths and dimensions capable of protecting publicly
funded upland infrastructure, habitable structures, etc.
b) The reconstruction and maintenance of a complimentary sand tube groin field at the
west end of South Beach intended to reduce (but not eliminate) sediment losses from
the beach fill to the adjacent federal navigation project channel which serves the Port
of Wilmington, NC., and
c) The introduction of a 1,300 ft. terminal groin constructed in 2015 at the juncture of
South Beach and the Cape Fear River. The design intent of the low profile rock
structure is to create an updrift sand fillet sufficiently broad enough so as to maintain
an improved shoreline orientation and berm width in an area of chronic erosion —
where beach fill alone has been incapable of reliably protecting upland properties and
infrastructure.
Two sources of beach quality sediment were preliminarily identified for purposes of
project construction and maintenance. The principal sand source was determined to be clean
littoral material routinely derived from improvements to, or ongoing maintenance of, a portion of
the entrance channel to the federally sponsored Wilmington Harbor Navigation Project. The
second primary source of available material was borrow sites) developed from abutting shoal
formations which had been deposited as a direct result of the navigation project. Utilization of

the latter sand source was determined to be a practical means of re-establishing natural sand
bypassing at the mouth of the Cape Fear River which had been eliminated by the navigation
works constructed at that location in the 1800's. Currently, the Village is likewise investigating
the development of a longterm borrow site within the extensive Cape Fear Shoals formation
lying seaward of the eastern end of Bald Head Island.
BACKGROUND
Since about 1974, beach erosion experienced along portions of the Bald Head Island
shoreline, NC has been principally manifest as "chronic" —with severe shoreline recession along
South Beach (most particularly the western portion nearest the inlet) and the seawardmost
segment of West Beach. The island's historical erosion is the apparent result of several
combined factors: (1) divergent alongshore littoral transport gradients near the center of South
Beach, (2) tidal currents and proximity to the Cape Fear River Entrance, (3) direct recurring
impacts associated with high frequency dredging operations required by the adjacent deep draft
federal navigation project, and (4) long term morphological changes in island configuration and
offshore ebb tidal shoal formations due to initial navigation channel construction, long term
maintenance practices and more recently, entrance channel deepening, widening and realignment
in 2000.
The Wilmington Harbor Entrance Channel, which extends several miles seaward of Bald
Head Island, is not stabilized by jetties and until a channel reconfiguration in 2000, had been
maintained at a single location and orientation by dredging since the late 1800's. In recent times,
but prior to the 2000 major modifications, maintenance of the entrance channel typically required
the removal and offshore disposal of between 500,000 — 1,000,000 cubic yards (cy) of beach
quality material each year. Beginning in 2000, the portion of the federal navigation channel
abutting Bald Head Island was deepened by four feet, widened at several locations, and
reoriented (see Figure 1). It is important to understand that the seven mile long offshore ocean
entrance segment of the navigation project was reoriented as part of the deepening project from
its historical location to a new location directly seaward of Bald Head Island through Bald Head
Shoal. The documentation of recurring impacts due to deepening, widening and reorienting the
channel in the vicinity of Bald Head Island has been a major focus of a Village sponsored annual

beach monitoring program. The latter was initiated in 1999 prior to, as well as in response to,
the ocean entrance channel's proposed reconfiguration and widening by the federal government.
As of May 2018, sixteen comprehensive Annual Monitoring Reports have been published (see
REFERENCE SECTION).
PLAN OF ACTION
In order to facilitate along -term program of engineered beach restoration, the Village of
Bald Head Island adopted a shore stabilization strategy predicated upon navigation project
related mitigation by State and Federal interests as the primary source of funding for sand
placement. Secondary sources of funding, as necessary, have derived from Village annual
revenues, the State of North Carolina and more recently the establishment of on -island special
purpose Taxing Districts. The latter are directed toward beach management and enhancement
activities and, in particular, beach restoration and ancillary shore stabilization structures
constructed and maintained by the Village as part of a longterm Plan.
For purposes of facilitating a major harbor deepening and widening program in 2000, the
Wilmington District USACOE formulated a project specific action element entitled the
Wilmington Harbor Sand Management Plan (WHSMP). The Plan was codified by State permit
for purposes of meeting State of North Carolina Coastal Zone Consistency requirements. For the
most part, the Plan was in direct response to the stated concerns and associated legal actions) by
the Village of Bald Head Island (VBHI) regarding both historical channel maintenance impacts
and potential new impacts of the deepening project to both the regional sediment budget and
Bald Head Island. The Plan's purpose was to reverse the highly impactive "standard practice" of
transporting beach quality sand removed from the channel during dredging activities to deep
water offshore disposal sites. Specifically the Plan called for the future placement of all dredged
beach quality sand directly onto adjacent beaches with special emphasis on Bald Head Island.
The initial construction of the widening/deepening project provided over 5 Mcy of high quality
sediment in 2000. Approximately 1.85 Mcy of that volume was used to initially improve the
entirety of South Beach at Bald Head Island. Over a typical six -year maintenance cycle, the
Wilmington Harbor Sand Management Plan proposed that approximately 1.0+ Mcy of sand
predicted to be dredged biannually as maintenance would be placed on the Beaches of Bald Head
Sept. 2018 - 4 - Olsen associates, inc.

VBHI —Engineered Beach Project
Island in year two and four (after initial construction) and on Oak Island/Caswell Beach during
year six. The 6-year cycle would then repeat. The two-year dredge and disposal cycle was
planned for the life of the project but is subject to alteration based upon impact documentation
and other relevant factors. Pragmatically, implementation can likewise be affected by
Congressional funding of such navigation works, etc. To date, federal funding shortfalls
associated with direct sand placement have been addressed by both the State of North Carolina
and the Village of Bald Head Island.
At this time, it is relatively clear that the Wilmington Harbor Sand Management Plan
provides a partial framework for the implementation of an "engineered" beach at Bald Head
Island. Since initial construction of the deepening project in 2000, six maintenance dredging
operations have been conducted within three inner channel segments closest to Bald Head Island.
Monitoring has conclusively shown that Bald Head Island needs sand every two to three years,
not the SMP's two out of three biennial events, Even though the placement of sand is
procedurally viewed as "disposal" by the USACOE, the tenets of the federal Plan allow the
coastal engineering consultant to the Village of Bald Head Island to strategically define the limits
of work and design templates to be filled throughout the project disposal area. By virtue of a
project specific updated "design", based upon comprehensive annual beach monitoring, the
Village of Bald Head Island is able to implement an engineered beach restoration project.
As an adjunct to the beach restoration project, the Village maintains amulti-structure
sand tube groinfield intended to limit shoreline recession in the area of most severe erosion
nearest the inlet channel. The groin field was required by, and is viewed as a favorable project
element by the USACOE since it correspondingly tends to reduce the amount of sand
entrainment caused by the navigation channel —and particularly immediately after each beach
fill placement operation at South Beach. In 2015, this groinfield was supplemented by the
construction of a 1,300 ft. long rock terminal groin —intended to further increase the longevity of
future beach fills constructed eastward thereof on South Beach.

projects constructed between 1991 and 1997 were cost -shared or paid for in their entirety by the
Village of Bald Head Island. Limited in scope, the three early sand placement efforts were not
highly successful in providing meaningful levels of shore stabilization due to their size. As a
result, the Village of Bald Head Island eventually adopted the long-range plan -of -action
discussed herein, i.e., comprehensive beach restoration via an "engineered project" construction
and commitment to long-term maintenance. That Plan -of -Action addressed both South Beach
and West Beach.

* Disposal pursuant to the WHSMP
The initial 2001, 1.849 Mcy comprehensive beach restoration project was constructed as
an element of the Wilmington Harbor Deepening Project. The disposal sand was placed in the
configuration of a designed berm along the entirety of the 15,500 feet of shoreline at South
Beach. The limits of work and design templates were provided to the Wilmington District by
Olsen Associates, Inc. on behalf of the Village. All work was performed in conformance with
the requirements of the SMP. The 2005, 1.2 Mcy beach disposal project was the initial
"maintenance" event (Year 2 of the SMP) of the scheduled disposal cycle and was constructed
Sept. 2018 - 6 - Olsen associates, inc.

VBHI —Engineered Beach Project
between November 2004 and January 2005. The 2006, non -Federal West Beach sand disposal
project was independently constructed by the Village in January 2006. Sand for that work was
sourced from Bald Head Creek.
The 2007, 1.1 Mcy disposal project was the second declared "maintenance" event (Year
4 of the SMP) and was constructed between February and Apri12007. Approximately 1,098,000
cubic yards (pay volume) of beach quality material was placed along the South Beach shoreline
in accordance with a fill design requested by the Village.
In 2009/10, the terms of the WHSMP dictated that the scheduled channel maintenance
sand be placed on Oak Island, in lieu of Bald Head Island. As a result, the Village constructed a
1.85 M cy beach fill along the majority of South Beach and a small section of West Beach which
fronts the inlet throat. The sand source was a borrow site developed and permitted by the Village
in Jay Bird Shoals. Portions of that borrow site continue to be available as a sand source today.
Detailed documentation for this Village project is included in Olsen (2010). It is noted that the
entire 16 sand filled tube groinfield was replaced immediately subject to beach fll completion.
Subsequent to the passage of H. Irene in 2012, a FEMA funded small scale fill project
was constructed along the western end of S. Beach. Five (5) sand tube groins damaged by the
storm were also replaced as part of that project. The project sand source was Bald Head Creek.
In 2013, the Wilmington District placed approximately 1.6 Mcy of channel maintenance
material along S. Beach and 92,500 cy along the southerly section of West Beach. Similarly in
2015, the District placed approximately 1.33 Mcy on South Beach with material sourced from
routine channel maintenance of the Cape Fear Entrance Channel (inner 3 sections).

funded by FEMA as part of a post -Irene damage
mitigation effort. The project P.W. was BHGJS04 in
accordance with FEMA declaration 4019 DR NC.
In the spring of 2015, construction was initiated on a
single 1,300 ft. long rock terminal groin designed to
complement future placement of beach fill at South

The structures which effectively contribute to the stabilization of Bald Head Island's engineered
beaches — as of the date of this report —are as follows:
• S. Beach —
0 1,300 ft. long terminal groin constructed in 2015;
o A sand filled tube groin field (originally 16 strux; 3 removed in 2015).
• W. Beach
o Rubble mound rock jetties at the marina entrance channel constructed in 2015.
o Two rock breakwaters constructed in 2017 seaward of Row -Boat -Row.
PROJECT DESIGN
South Beach. The project renourishment design for South Beach calls for the placement
of approximately 1 Mcy of sand every two to three years from the local navigation project with
supplementary renourishment, as required, from alternate borrow sources) developed and
permitted by the Village. The project likewise provides for the continued use of structures at the
western end of the South Beach fill segment, intended to increase project life. The project limits
on South Beach extend approximately from Sta 045+47 to Sta 210+00, or nominally about
16,000 ft. plus fill tapers at both ends (see Figure 2). Atypical fill template for S. Beach is
depicted by Figure 3.
Appendix A to this document includes beach profiles which depict the conditions of the
project beaches along South Beach as they existed in May 2018 —prior to the 2018 hurricane
season. Normally project fills are constructed within a permit required environmental window
which necessitates that completion of fill activities occur between Nov. and April of any one
year —except during emergency situations where waivers may be granted.
West Beach. The island's "engineered beach" systems likewise includes an approximate
2,100+ ft. long segment of shorefront along West Beach (see Figure 2). Given the steep
nearshore slope of the submerged portion of this river -affected shoreline, a fill density of 30
cy/ft. is typically the maximum for this area (see Figure 3). Including tapers, the net fill
episodically placed at this location is estimated at about 100,000 cy, or less. West Beach
shoreline conditions are likewise comprehensively monitored annually by the Village of Bald
Head Island.

In 2016/17, the West Beach segment of improved shorefront was extended to include some 1,400
ft. of shorefront located northward of the marina entrance —typically referred to as Row -Boat -
Row (see Figure 2). Stabilizing structures maintained at that location include two (2) rock
breakwaters constructed in 2016, and four (4) low profile groins last renovated in 2005. Row -
Boat -Row is separated from the southerly portion of West Beach by two (2) rock jetties
constructed in 2015. The latter structures protect the marina entrance channel which is an
integral part of the island's water -borne transportation system which is served only by ferry and
barge. Photographs of stabilizing structures discussed herein are included in Appendix B.
PROJECT DOCUMENTATION
In order to document shoreline changes along the South Beach and West Beach portion
of the island's "engineered" beaches, the Village of Bald Head Island has routinely funded an in-
depth annual beach monitoring program. Since 1999, the program has been expanded from
annual surveys to include two (2) surveys (spring and fall) and two (2) aerial overflights which
result in digital, rectified shoreline photography. An annual report of findings is published which
addresses both the prior 12-month period as well as special events (i.e., dredge operations) and
other longer term trends are included. The monitoring program specifically addresses beach fill
performance and provides guidance for the design of each episodic sand placement operation.
The spring hydrographic surveys are scheduled to document beach conditions immediately prior
to each hurricane season in order to comply with FEMA related post -disaster eligibility
requirements.
The beach monitoring program presently being implemented by the Village of Bald Head
Island's engineered beaches is based upon a baseline with survey stationing located on
approximate 400 ft centers. As shown by Figure 4, the baseline limits extend from Row -Boat -
Row, located northward of the entrance to the Bald Head marina (Sta 0+00) southward along
West Beach some 4,500 ft to the "Point" (or depositional spit) abutting the existing navigation
project channel and thence eastward to Cape Fear along South Beach, an additional 17,300 ft,
mol. The baseline stationing is referenced to the North Carolina State Plane Coordinate System,
North American Datum of 1927 (NAD27).

Island -wide beach monitoring baseline.
Olsen associates, inc.

VBHI —Engineered Beach Project
Some level of beach monitoring has been performed at Bald Head Island since about
1990. Initially, surveying was limited to beach profiles from the back berm to a wading depth.
In the mid-1990's offshore profiles to a depth of -30 ft or a distance of 3,000 ft were added to the
program. In 2009, the program was expanded to include East Beach —pursuant to the request of
property owners at that location (see Figure 4). As a result, the entire monitoring baseline length
exceeds30,000 ft.
Tidal Datums —The elevations and water depths along each of the survey profiles are
referenced to National Geodetic Vertical Datum of 1929 (NGVD29). The relationship between
NGVD29 and various tidal datums are as follows:

PROJECT PUBLIC ASSISTANCE ELIGIBILITY
Section 102(8) of the Stafford Act defines a public facility owned by a State or local
government as any flood control, navigation, irrigation, reclamation, public power, sewage
treatment and collection, water supply and distribution, watershed development, or airport
facility; any non -Federal -aid street, road or highway; any other public building, structure, or
system, including those used for educational, recreational, or cultural purposes; and any park.
Additionally, Title 44 of the Code of Federal Regulations (CFR), Section 206.201(c) includes an
improved and maintained natural feature in the definition of a facility. 44 CFR 206.221(d)
defines an improved property to mean a structure, facility or item of equipment that was built,
constructed or manufactured. Publicly -owned engineered beaches are eligible for assistance
Sept. 2018 - 14 - Olsen associates, inc.

VBHI —Engineered Beach Project
because they are improved natural features, assuming they have been regularly maintained prior
to the disaster. The engineered beach segments at Bald Head Island, N.C. meet the criteria of a
publicly -owned non -Federal engineered beach. Concurrent with ongoing commitments by the
Village to fund the project construction, the local sponsor has the capability and intent to
facilitate or perform the requisite future maintenance of the beach fill project for the long-term
project life of greater than 30 years.
Section 206.226 Restoration of damaged facilities, further defines eligibility criteria for
Beaches. For an improved beach, work to re-establish the beach as infrastructure may be eligible
under the following conditions:
a) The beach was constructed by the placement of sand (of proper grain size) to a
designed elevation, width and slope, and
b) A periodic maintenance program involving periodic renourishment of sand has been
established and adhered to by the Applicant.
Implicit in these regulations is the requirement of an Applicant to document the condition
of the affected shoreline prior to impact by the storm which results in the declared disaster. As
noted above, the comprehensive beach monitoring program implemented annually by the Village
of Bald Head Island specifically seeks to fulfill that requirement.
POST -STORM ACTION PLAN
Immediately subsequent to a major storm event for which a formal disaster declaration
may (or will in all probability) be issued, the Village will initiate the following Action -Plan
elements:
• A comprehensive survey of the affected beaches by a certified hydrographic survey
firm,
• Concurrent drone photography and eventual digital orthophotography (island -wide),
• Analysis of storm induced shoreline volumetric erosion, shoreline recession,
vegetation/dune impacts, etc.,
• Assessment and documentation of damage to infrastructure and development,
Sept. 2018 - 15 - Olsen associates, inc.

VBHI —Engineered Beach Project
• The formulation of an engineering report of post -storm conditions suitable for review
and consideration by FEMA staff authorized to issue P.W.'s.
• The submittal of all relevant documentation as to the existence of an "engineered
beach" required by FEMA staff, and
• As applicable, any requested letters -of -opinion, computations, or recommendations,
by a State of N.C. registered coastal engineer requested by FEMA, Brunswick County
or the State of NC.
