By way of this email, LMG is requesting that NC DWR remove the voluntary hold placed on the modification request to
the State 401 Certification for the Village's proposal to nourish South Beach. As indicated previously, the Village is
proposing to prioritize the use of Jay Bird Shoals as a sand source site for more immediate nourishment needs on South
Beach. Erik Olsen has prepared revised permit drawings reflecting the updated proposed project (I will forward his
submittal under separate email). In light of these revisions, we request the NC DWR resume the processing of the 401
Certification modification request.
Please call or email me should you have any questions or require any additional information.
Thanks,

RE: CAMA Permit Request — Major Modification
To State Permit No. 91-14 and Federal Permit SAW -2012-00040
Jay Bird Shoals Beach Nourishment Project
By the Permittee: Village of Bald Head Island (VBHI), N.C.
o'sen
associates, inc.
Coastal Engineering
As you are aware, the VBHI recently requested a "hold" be placed on a previous request
to modify the above permits for purposes of constructing Beach Nourishment activities utilizing
a proposed Frying Pan Shoals (FPS) borrow site. It is currently the intent of the Permittee to
seek permits for that work under separate and distinct State and Federal permits and not as
modifications to original terminal groin permits discussed herein. Please expect the requisite
FPS borrow site applications to be submitted by LMG — as Permit Agent.
Conversely, the Village now desires to receive a major modification of said permits to
allow for the one time use of an alternate sand source located within Jay Bird Shoals, as
recommended by the NMFS. Simplistically, the VBHI needs to construct a 1 Mcy beach fill at
South Beach from the terminal groin to Sta. 134+00 (9,000 ft to the east). Simplistically, the
purpose of the fill is four -fold:
• To replace accelerated storm induced sand losses occurring since the last federal beach
disposal operation at South Beach in 2015,
• To keep the terminal structure updrift fillet full pursuant to N.C. Statutory requirements
for purposes of ensuring some level of sand transport to the downdrift shoreline (i.e. West
Beach),
• To protect publicly owned infrastructure, habitable structures, and
• To protect extensive dune resources and sea turtle nesting habitat.

www.olsen-associates.com.

BACKGROUND FOR THE REQUEST FOR PERMIT MODIFICATION
VBHI annual Monitoring Report No. 15 (Olsen 2017) documented that between April
2016 and May 2017, South Beach at Bald Head Island lost a total of 619,000 cy (above elevation
-16 ft NGVD). This amount well exceeded average annual losses measured over the last 17
years and was principally due to the effects of Hurricanes Hermine and Matthew in 2016. As a
result, the Village Council has authorized the design and permitting of the 1 Mcy interim beach
fill discussed above to be constructed in the fall/winter of 2018/19 — at the latest.
Recently, formal permit applications for the development of a long-term borrow site
within Frying Pan Shoals were being processed. Those applications requested a major
modification of State Permit No. 91-4 and federal permit SAW -2012-00040 — which were issued
for both the terminal groin constructed in 2015 and subsequent fill activities required to keep the
structure updrift fillet full pursuant to N.C. Statutory requirements. On 27 July 2017 that
Application was put on hold by LMG — as Permit Agent.
In June 2017, the National Marine Fisheries Service (NMFS) issued concerns related to
the near term use of the Frying Pan Shoals (FPS) borrow site without first exploring and
exhausting other viable sand -source alternatives. Realistically, the only alternate borrow area
available for near term sand placement at Bald Head Island (BHI) is sand remaining in the
previously permitted JBS borrow site. Accordingly, in consideration of the NMFS request, the
Village has agreed to prioritize the use of the previously authorized borrow site permitted at Jay
Bird Shoals (JBS) (including both the partially recovered area dredged in 2009/10 and the
remaining undredged portion of the borrow site). Options other than JBS and FPS are not
feasible at this time. For instance, there is not sufficient sand volume within the two Bald Head
Creek borrow area(s). Moreover, only a very small dredge can be utilized at that location.
Therefore, the Bald Head Creek site is not suitable for any large-scale nourishment event at S.
Beach. With respect to the Wilmington Harbor Channel as a potential sand source, all sand to be
excavated by the Corps of Engineers (COE) in 2017/18 as part of their regularly occurring
channel maintenance program will be placed on Oak Island pursuant to the terms of the
Wilmington Harbor Sand Management Plan (WHSMP). Hence, there will not be sufficient sand
-2-

quantities from that source available to the Village in the near future for placement at South
Beach. It is estimated that the next federal disposal operation at BHI will not be until 2020/21.
Within the originally developed JBS borrow site, the most recent monitoring surveys
(Olsen 2017) document that there is an estimated 900,000 of sand remaining in the undredged
portion of the site — lying outside a Cultural Resource Exclusion area. Additionally, there is
almost a similar volume of depositional material which lies within the area previously excavated
in 2009 — although not all of it is accessible by a dredge. The predicted volume required to be
placed within a design template on South Beach in 2018/19 is approximately 1 Mcy.
The one time use of the JBS site (if viable in terms of both sand quality and quantity)
would address the more immediate nourishment needs for South Beach and the terminal groin
fillet. It should be noted that a long-term borrow site consisting of large volumes of beach -
compatible sand (from a borrow site exhibiting physical conditions conducive for relatively rapid
recovery) will ultimately be needed to offset long-term sand deficits along South Beach and
West Beach. To that end, the Village intends to reinitiate permits needed for the future use of the
proposed FPS borrow site. In the interim, use of the JBS site will likely be able to address the
more immediate nourishment needs while deferring and ultimately reducing the near-term
physical disturbance to the FPS site — pursuant to the request of the NMFS.
The original 226 Acre JPS borrow area as developed for the locally constructed 2009/10
beach fill was defined by approximately 31 VIBRACORES (see Figure 1). To a dredge depth
of -24 NGVD 29, the site contained approximately 3 Mcy of available beach quality sand — not
including a 12.5 A Exclusion Area associated with potential cultural resources (TAR 2007).
Over the course of the 2009 project, approximately 158 A of seabed within the permitted borrow
site were dredged (see Figure 2) yielding a gross fill volume of about 1.85 Mcy. As shown in
Figure 3, the dredge contractor was strategically limited to working only within Borrow Site
Sub -Areas 1 and 2, thereby intentionally leaving Area 3 for future use. The residual volume of

available sand within Area 3 after construction exceeded 1 Mcy. The 2009/10 project was
constructed by Norfolk Dredging Company using an Ocean Certified 27" cutter suction dredge.
During the permitting of the JBS borrow area, Olsen Associates, Inc. performed
numerical modeling of a theoretically excavated borrow site for purposes of evaluating any
potential impacts to the shores of Oak Island (Olsen 2007b). In addition, during the permitting
of the 2015 terminal groin project, a separate and distinct borrow site impact analysis was
performed using the more robust DELFT 3D numerical model (Olsen 2013). Both modeling
investigations conservatively assumed the JBS borrow site was theoretically excavated in its
entirety (as well as the Cultural Resource exclusion area) — when in reality the site was only
2/3 d' excavated. Neither in-depth numerical modeling study predicted quantifiable impacts to
Oak Island.
None -the -less, when Permits for the terminal groin were issued by State and Federal
agencies in 2014, a Condition was added at the request of certain interests on Oak Island that
should the permittee receive a future permit modification to dredge more than 250,000 cy of
material from the JBS borrow site (presumably from the remaining unexcavated Area 3), the
Village would be required to monitor and analyze a large segment of eastern Oak Island for
potential project impacts. At the time of permit issuance, severe time constraints associated with
the bid and construction schedule for the terminal groin necessitated that the Village not seek to
challenge such a Condition. In order to comply with the recently stated request of the NMFS,
the Village is now requesting a permit modification authorizing the one time dredging of
approximately 1 Mcy of sand from the JBS site. More specifically, in consideration of the above
permit Condition, the Village is seeking a permit modification to excavate 750,000 cy from
dredge Areas 1 and 2 which have infilled with depositional of sand since the 2009 dredge project
and to obtain the remaining needed volume of 250,000 cy from the unexcavated Area 3 portion
of the site. It is believed that such a dredge plan should be deemed favorable at this time based
upon the following considerations:
SIA

1. It potentially defers the use of the FPS borrow site over the next several years (possibly
up to a decade into the future) pursuant to the recommendations of the NMFS.
2. It meets the intent of the original terminal groin Permit Condition which limits the
volume of dredging to 250,000 cy in the remaining unexcavated portion of JBS (i.e. Area
3) without triggering intensive monitoring of the Oak Island shoreline, or the requirement
for the Village to formally challenge the basis of the Condition; and
3. It addresses the requirement stipulated by both Permit Condition and State Statute for the
Village as Sponsor of the 2015 terminal groin project to keep the updrift fillet of the
structure full.
JBS BORROW AREA RE-EVALUATION
The developed JBS borrow site in its entirety has been surveyed by the Village every 1 to
2 years subsequent to its use in 2009110. The April 2017 monitoring survey shows areas of gross
deposition amounting to 891,000 cy. It is therefore possible to construct a 1M cy beach fill
utilizing depositional material within borrow site Areas 1 and 2 (which is accessible to a dredge)
in combination with 250,000 cy from the previously unexcavated Area 3.
For purposes of this permit modification, the Village recently authorized the rapid
acquisition of 8 VIBRACORES within the largest candidate depositional area in order to verify
sediment quality or acceptability as beach fill at South Beach (see Figure 4). All depositional
material encountered was classified as SP and found to be beach compatible pursuant to criteria
established by the State of N.C. All geotechnical results are presented in the report entitled,
"Bald Head Island, N. C Jay Bird Shoals Borrow Site Re-evaluation" dated August 2017 (copy
attached).

In summary, the Village of Bald Head Island is requesting a modification of CAMA 91-4
and USACE No. SAW -2012-00040 sufficient to dredge portions of a previously developed
borrow site located at Jay Bird Shoals. More specifically, a contract will be formulated whereby
250,000 cy would be dredged from Area 3 of the site which was not designated for excavation in
2009/10. An additional volume amounting to 750,000 cy, mol. would be excavated from
material deposited within Areas 1 and 2 of the JBS borrow site which were previously dredged.
A "dredge plan" defining these two areas of work is included as Figure 5. It should be noted
that not all depositional material in Areas 1 and 2 is physically accessible by a large ocean
certified dredge. All sand would be placed on S. Beach from the terminal groin eastward
approximately 9,000 ft. The proposed timing of the work would be between 1 November 2018
and 1 April 2019, unless storm impacts and emergency conditions dictate otherwise. Work
would be performed by an ocean certified cutter suction dredge with direct deposit on S. Beach
by pipeline. Where the submerged pipeline crosses the federal navigation project, it would need
to be placed below the authorized channel depth of -44ft. MLW. Any such material excavated to
trench the pipeline below the channel would be placed on S. Beach — as was done for the 2009
project.
The sediments within the original Jay Bird Shoal borrow site limits (Areas 1, 2 and 3)
were originally determined to be beach compatible by way of a comprehensive Sand Search
(Olsen, 2007a) performed prior to the 2009 locally constructed beach restoration project. A
Cultural Resource Exclusion Zone totaling 12.5 A was required at the time. With further field
investigations, the spatial limits of that Zone may be subject to reduction. Such an evaluation by
Tidewater Atlantic Research has been authorized.
Depositional sediments which are being proposed for re -excavation during a beach fill
project in the winter of 2018-2019 were evaluated through the acquisition of eight (8) additional
VIBRACORES in July of 2017 by the firm of Athena Technologies, Inc. Subsequent laboratory
analyses of composite samples over the assumed depth of excavation — i.e. from the existing

seabed to -24 ft NGVD29 — were performed and reported. The design depth for all future
excavation will be to -24 ft NGVD (+2 ft tolerance). All composite sample sediments over depth
meet State Standards for placement as beach fill on South Beach at Bald Head Island. The
proposed limit of fill would extend from the western side of the terminal groin to baseline Sta.
134+00 located approximately 9,000 ft. eastward thereof — as addressed by the original 2014
permits discussed herein.
In addition to all Figures referenced above, we are enclosing the following items
associated with this request for Permit Modifications:
• A digital copy of the geotechnical report for the recent JBS borrow site re-evaluation
• A set of additional permit drawings (6 Sheets dated 15 September 2017) addressing the
details of the proposed activities. These are intended to supplement the 21 Sheets
associated with the original Terminal Groin permit (as issued).
• A list of reports referenced by this request.
We assume no fee is required at this time due to that submitted previously for the FPS permit
modification (which has been withdrawn). Please advise if this is incorrect. It is our intent to
schedule an interagency meeting at the earliest date possible with all affected parties, to make a
Power Point presentation and to address questions and/or concerns at that time related to this
request to modify State and Federal Permits.
Thank you for your consideration in this matter.
