Oak Island Renourishment Project 2021/2022 Design
Project construction began on February 20, 2022 and was completed on April 20, 2022 (59 days) by Great
Lakes Dredge and Dock Company Inc. (GLDD). Moffatt & Nichol (M&N) served as the engineer on behalf
of the Town of Oak Island (Town). The project design consisted of approximately 765,000 cubic yards (cy)
to be placed along 21,500 feet (ft) of shoreline (approximately 4.1 miles) from 3rd Place East to the west
end parking lot as shown in Figure 1.

Figure 1. Oak Island Renourishment Project 2021/2022 Beach Fill Extent (Sta 465+00 to Sta 680+00)
Jay Bird Shoals and Central Reach, shown in Figure 2, were the authorized offshore borrow areas.
However, all but a few loads were dredged from Jay Bird Shoals due to sediment compatibility issues in
Central Reach.

The design template consisted of four typical cross-sections which varied based on two dune tie-in
configurations and the presence or absence of a berm. Figure 3 shows the two typical dune tie-in
configurations without a berm and Figure 4 shows the two typical dune tie-in configurations with a berm.
The design template consisted of a dune designed to withstand a 25-year return period storm. The dune
elevation ranged from 13.0 to 15.5 ft North American Vertical Datum 1988 (NAVD88) with a crest width
of 10 ft in most locations. However, due to existing grade some locations featured a direct horizontal tie-
in to existing ground with varying dune crest width. The front slope of the dune was 4 Horizontal:1 Vertical
(H:V) and the back slope of the dune, where applicable, was 5H:1V. The front dune slope broke at
elevation 7.0 ft NAVD88 and continued out on a 20H:1V slope until tie in with existing grade from
approximately Sta 465+00 to Sta 620+00. From Station 621+00 to Station 677+00 a variable width berm
ranging from 60 ft to 65 ft at elevation 7.0 ft NAVD88 was also included in the design to account for
accelerated erosion historically experienced on the west end of Oak Island.
The construction plans detailing the placement extents, cross-sections, and borrow areas are show in
Appendix A.

Oak Island Renourishment Project 2021/2022 Construction
As part of the construction administration for the project the Contractor generated daily QC Reports
covering all aspects of construction and Moffatt and Nichol produced summaries of the weekly
construction meetings between Owner, Contractor, Engineer, and Agencies to document all construction
activities, both of which can be found in Appendix B. In addition, environmental permitting
documentation which guided and established requirements for all aspects of construction activities can
be found in Appendix C.
Beach Placement
As mentioned previously, project construction began on February 20, 2022 with Padre Island which was
joined by the Dodge Island on February 21, 2022. The two dredges worked in tandem throughout most
of the project, with the Padre Island departing on April 6, 2022, just two weeks before the completion of
the project. The project required the use four different sublines spaced evenly along the project extents,
two of which used a booster. In general, the western portion of the project was constructed first and then
the eastern portion of the project was constructed. The first subline at Sta 608+50 (w/ booster) was
utilized to pump east to Sta 572+00 and then west to Sta 642+00. The contractor then moved to the
second subline at Sta 656+50 (w/o booster) where they pumped east to tie-in at Sta 642+00 and then
west to the western project limit at Sta 680+00. The contractor then moved to the third subline at Sta
534+50 (w/ booster) which was utilized to pump west to tie-in at Sta 572+00 and then east to Sta 520+00.
The fourth subline was located at Sta 489+50 (w/o booster) and was utilized to pump west to tie-in at Sta
520+00 and then east to the eastern limit of the project at Sta 465+00.
It was originally intended that the sublines utilizing the booster would place material dredged from Jay
Bird Shoals and the sublines not using a booster would place material from Central Reach. However, after
starting with material from Jay Bird shoals on a booster subline some test loads from Central Reach were
dredged to prepare for the switch to a non-booster subline. During this process it was determined that
the material from Central Reach was not compatible and an official change was made to the construction
process in which the contractor was directed to dredge all remaining material through completion of the
project from Jay Bird Shoals. Due to the change in borrow area, which required an increase in price due
to borrow area distance, the overall design volume was reduced from 765,000 cy to 745,000 cy in order
to keep the overall contract price the same. This volume reduction was accomplished by reducing the
initial 60 ft to 65 ft berm width intended for Stations 621+00 to 680+00 on the western end of the project
down to 35 ft to 45 ft. In addition, to combat erosion which had occurred since the pre-construction
survey was performed, the entire template (dune and slope) along three stretches of shoreline in the
portion of the project not containing a berm from Sta 467+00 to Sta 487+00, Sta 511+00 to Sta 525+00,
and Sta 569+00 to Sta 616+00 were shifted 5 ft landward.
Although the final design volume was reduced to 745,000 cy, storm activity which occurred during the
project, extra material required to properly tie-in the dune to existing ground, and some general overfill
due to contractor placement accuracy during construction caused the project to reach completion on April
20, 2022 with a total of approximately 768,063 cy of placement.
Figure 5 through Figure 9 presents example before and after project conditions of Station 620+00 from a
cross section, aerial, and ground view. All cross sections and volumes for the project can be found in
Appendix D.

Tilling
Sediment quality resulting from the Phase I 2020/2021 Oak Island Renourishment Project resulted in the
requirement to perform tilling in last year’s project area as well as the Phase II 2021/2022 project area
after construction was complete. Therefore, throughout the beginning to middle of March (March 9 – 10
& March 13 – 15), the Phase I 2020/2021 project area was tilled. Upon completion of the western half
the of Phase II 2021/2022 project, tilling was completed from the west end parking lot to 51st Pl W at the
end of March. Upon completion of the eastern portion of the project, tilling from 51st Pl W to 3rd Pl E was
completed at the end of April once all equipment was off the beach. Tilling was performed from the base
of dune out to Mean High Water (MHW). GLDD was able to till the areas of concern prior to April 30, 2022
using the equipment shown in Figure 10.

Post & Rope
In conjunction with the beachfill placement, post and rope fences were installed, by GLDD’s subcontractor
Emerald Forest Incorporated, at emergency vehicle accesses, public beach accesses, and homeowner
walkovers (approximately every 200 ft). All access points were identified by Town staff. Emergency
vehicle accesses and public vehicle accesses were 10 ft wide and the homeowner walkovers were 5 ft
wide. Due to a delay in receiving the supplies, GLDD installed temporary stakes and tape fences to guide
the public over the dunes to prevent foot traffic where not intended until the post and rope were
delivered and installed. Approximately 8,170 ft of post and rope were installed throughout the project.
An example of the post & rope is presented in Figure 11.

Oak Island Renourishment Project 2021/2022 Borrow Area Utilization
Jay Bird Shoals
The Jay Bird Shoals borrow area is located approximately one (1) mile off the shore of Caswell Beach (east
of Oak Island) near the mouth of the Cape Fear River (see Figure 2). The borrow area was divided into 3
zones with different target elevations to conserve material for future projects. The permitted elevations
for the Zones were as follows: Zone 1 -28 ft NAVD88, Zone 2 -37 ft NAVD88, and Zone 3 -29 ft NAVD88.
These elevations include a two foot overdredge which was allowed in each zone.
A magnetic anomaly stretches diagonally across Zone 3 and part of Zone 2. A 50 ft buffer was applied to
either side of the magnetic anomaly during dredging. In addition a portion of Zone 1 was excluded due
to incompatible material.
Pre- and post- dredge surveys were taken of the borrow area in January and May 2022, respectively, to
determine dredge impacts. These surveys are presented in Figure 12.

Figure 12. Jay Bird Shoals BD and AD Surveys
The difference in elevation between the BD and AD surveys was then calculated to determine the change
in the borrow area as a result of dredging. Elevation differences are presented in Figure 13. Elevation
differences less than 0.5 ft were excluded from the color scale to clearly identify areas that were dredged.
As can be seen, the majority of dredging occurred in Zone 2 with some dredging occurring along the
southwest boundary in Zone 3 and minimal dredging occur right at the southern boundary of Zone 1
where it intersects with Zone 2. The deepest dredge cut was 14.01 ft. It is estimated that 19,934 cy of
material was removed from Zone 1, 1,007,841 cy from Zone 2, and 74,068 cy from Zone 3 for a total of
Final Report Oak Island Renourishment Project 2021/2022
12

1,101,842 cy of dredging. It should be noted that some natural accretion, up to 2.5 ft, occurred in Zone 1
and Zone 3 in the 4 months between surveys as represented by the pink color shading in Figure 13. More
information about the borrow area utilization, including load by load dredge production information and
daily dredge track lines, can be found in the daily QC reports in Appendix B.

Figure 13. Jay Bird Shoals Borrow Area Cut Depths
Central Reach
The Central Reach borrow area is located approximately 2.3 miles offshore of Oak Island, just west of the
Middleton Avenue bridge (see Figure 2). The borrow area was divided into 4 zones with different target
elevations based on sediment compatibility. The permitted elevations for the Zones were as follows: Zone
1 -40 ft NAVD88, Zone 2 -41.7 ft NAVD88, Zone 3 -39.9 ft NAVD88, and Zone 4 -42.0. These elevations
include a two foot overdredge which was allowed in each zone. A portion of the borrow area spanning
all four zones was excluded from use due to use by the adjacent project on Holden Beach.
Pre- and post- dredge surveys were taken of the borrow area in January and May 2022, respectively, to
determine dredge impacts. These surveys are presented in Figure 14.
Final Report Oak Island Renourishment Project 2021/2022

Figure 14. Central Reach BD and AD Surveys
The difference in elevation between the BD and AD surveys was then calculated to determine the change
in the borrow area as a result of dredging. Elevation differences are presented in Figure 15. Elevation
differences less than 0.5 ft were excluded from the color scale to clearly identify areas that were dredged.
It should be noted that only a few test loads were dredged out of the Central Reach borrow are before
the material was deemed to be poor quality and the contractor was directed to use Jay Bird Shoals as the
sole sediment source. Therefore, the differences in the BD and AD surveys are very minimal. As can be
seen, only a few track lines are visible based on the elevation changes in the borrow area. Minimal
dredging was performed in Zones 1, 2, and 4. The deepest dredge cut was 1.94 ft. It is estimated that
51,998 cy of material was removed from the Central Reach Borrow Area in Zones 1, 2, and 4. More
information about the borrow area utilization, including load by load dredge production information and
daily dredge track lines, can be found in the daily QC reports in Appendix B.

Oak Island Renourishment Project 2021/2022 - Other Project Features
Relocation Trawling
Trawling activities were initiated 24 hrs prior to start of construction. Subcontractor Coastwise Consulting
performed the trawling and relocation activities. One trawler (Lady Paige) was on site throughout the
entire project which was deemed sufficient due to the fact that the dredges would be digging in the
borrow area at alternating times. Daily trawl relocation reports, sturgeon capture and relocation forms,
sea turtle capture and relocation forms, and dredge sea turtle take forms can be seen in the daily QC
reports in Appendix B. Throughout the project, the following relocations and takes occurred:
• Atlantic Sturgeon: 27 non-lethal relocations
• Green Turtle: 0 non-lethal relocations
• Loggerhead: 9 non-lethal relocations, 1 lethal dredge take
• Kemps Ridley: 19 non-lethal relocations, 1 lethal dredge take
• Leatherback: 1 non-lethal relocation

Sediment Sampling
Due to initial concerns about sediment quality, it was decided that the twice a week sediment sampling
requirements in the specifications should be increased to daily sediment sampling until all parties were
comfortable with material quality. Therefore, sediment sampling was performed on a daily basis from
February 21, 2022 to March 9, 2022 after which the protocol switched to collection of samples every other
day for the remainder of the project. Table 1 presents a summary of the sediment samples results
throughout the project. As can be seen, a majority of sediment samples met the State sediment criteria
of ≤6% gravel, ≤11% granular, ≤7% fines, and ≤25% calcium carbonate. It should be noted that a sediment
sample at Sta 562+00, taken in early April, did not meet the gravel, granular, or calcium carbonate
requirements. However, samples taken before and after did meet the State requirements, indicating that
it was likely a small pocket of incompatible material which was dredged from the borrow area and did not
impact a large portion of the beach. Sediment sample lab analysis tables and graphs can be seen in
Appendix E. In addition to grain size analysis, wet and dry Munsell Color was also documented to alleviate
agency concerns about sediment color, specifically darkness of material, that could impact sediment
temperature which has been correlated to affecting the gender of newly hatched sea turtles.

Table 1. Sediment Sampling Lab Analysis Summary

Beach Raking
As a result of last year’s project and conditions at an adjacent beach using material from Central Reach,
contract and permit requirements specified beach raking should occur before and after construction to
remove surface rocks. However, pre and post construction conditions were document by GLDD indicating
beach raking did not need to occur. The permitting agencies were in agreement that the beach raking
operation could be dismissed due to the absence of rocks on the beach before and after placement.
Therefore, change orders were developed to remove this process and fee from the overall project.

Dune Planting
Under a separate contract, the Town entered into agreement with subcontractor Coastal Transplants to
grow and plant 275,000 plants along the crest and landward slope of the dune. Dune planting began on
May 23, 2022. All plants grown and installed were Sea Oats and were installed with 24 inch spacing. The
contractor completed initial planting in the project area on June 29, 2022. Due to dry weather, the
contractor immediately returned to replant several areas that did not survive, finishing on July 25, 2022.
One additional area was replanted at the end of August. Upon project completion, approximately 245,200
plants were installed, 44,400 of which were replacement plants for those that did not survive the dry
weather during planting. A final walkthrough was performed on September 26, 2022, establishing an 80%
survival rate as required by the contract. The contractor utilized UTV’s and small trailers to haul

equipment (plants, hoses, tools, coolers, markers) with blue lay flat hose for water. Guidance by the
permitting agencies concerning equipment restrictions and coordination regarding turtle monitoring were
followed. Figure 16 presents an example of the dune planting.

Temperature Monitoring
A site visit was conducted on April 28, 2022 to install waterproof temperature loggers within the
2020/2021 and 2021/2022 placement areas to collect sand temperature data. Four temperature loggers
were re-installed within the 2020/2021 renourishment area (SE 58th St, 29th Pl E, 11th Pl E, and 6th Pl E) and
six temperature loggers were installed within the 2021/2022 renourishment area (5th Pl W, 17th Pl W, 27th
Pl W, 42nd Pl W, 51st Pl W, and 57th Pl W). Two control station loggers were installed on ether end of Oak
Island at the west end parking lot and SE 67th St. The loggers were buried at a depth of 18 inches (which
represents sea turtle nest depth) along the face of the dune, approximately halfway up the dune face or
at an elevation of 12 ft NAVD88. Data will record temperatures at 1-hour intervals through summer 2022.
Data will be downloaded every two weeks and will be provided to the agencies. Each monitoring station
will include color documentation every two weeks. Sediment color will be monitored 6 inches from the
surface. Photos of the dune and shoreline will be collected at each sampling location to establish a visual
log. Figure 17 presents the ten monitoring locations within the project areas and 2 control stations.

Oak Island Renourishment Project 2021/2022 Final Cost and Funding
The final construction cost of the project, excluding engineering, was $17,648,935.15. This is just slightly
higher than the original awarded amount of $17,134,000.00 due to a small overage in final pay volume
and use of Jay Bird Shoals for the entire project.
The project was funded partly by the Federal Emergency Management Agency (FEMA) Hurricane Matthew
claim of approximately $7.6M. Additional grant money to extend the scope of the project was received
from the Hurricane Florence Disaster Recovery Fund Coastal Storm Damage Mitigation of approximately
$1.3M. The Town paid for the remaining portion of the project ($8.7M).
