Hi folks,
Please see the attached revised project submitted by TI Coastal for the Topsail Beach project. The cut -through channel
has been realigned to the west to minimize encroachment into the Primary Nursery Area and the portion remaining
within PNA has been reduced in scope to previous 2010 dredge dimensions. Another vibracore was also taken in the cut -
through channel and sediment compatible analysis has been reworked to account for the new channel location. Please
see the attached supplemental info and let me know if you have any questions, comments or concerns. The second
attachment contains the revised Geotech and plans (revised plans can be found on pages 20-21). A link to the complete
set of updated plans on Ti Coastal's share site can also be accessed and downloaded here:
https://ticoastal.egnvte.com/dl/xT3t7W8X2O. Please note there are some minor discrepancies between stations and
volumes given in the first attachment and the tables on the revised plans. I believe this is due to Jamie reworking the
"spider map" due to the new vibracore, although I will check on this and will let you know if there are any further
changes.
Thanks in advance for any comments you provide!

Good Afternoon Heather -
Please see attached PDF containing geotechnical information in regards to the Cut Through Channel. The core was
collected last Wednesday and I finished up our analysis of it this morning. Included are updated composite statistics for
all the channels as well as the cut through channel itself, a map of all our vibracores, and the individual geotech analysis
for Vibracore 66, taken in the cut through channel. Additionally, I have updated the full set of plans for the Topsail Beach
Project to include our modifications to date. Please use the link below to download the PDF. If you have any questions,
please let me know. Thanks!

Permit Modifications
TI Coastal Services submitted a major modification to the Town of Topsail Beach's CAMA permit #22-09
on January 29, 2018. This application proposed increasing the channel widths of previously dredged
navigation channels within New Topsail Inlet and the New Topsail Inlet channel complex. The additional
width of the dredge cut provides shoaling capacity to extend the project lifespan from 3 years to 5 years,
while simultaneously providing sufficient beach quality sand to nourish the Town's beaches to the
Federal CSDR project standards.
Since that time multiple discussions have occurred to address concerns of the State and Federal
permitting agencies, resulting in modifications to the original permit application package. Included in the
changesare:
1) Channel dredging in Banks Channel will cease at station 210+00 as our current vibracoring
efforts did not extend past this point.
2) The layout of Banks Channel has been shifted slightly in areas to avoid potential SAV impacts.
The NCDEQ Fisheries Resource Specialist indentified areas less than -4' Mean Low Water as
potential SAV habitat. The Banks Channel alignment was adjusted slightly to avoid all impacts to
water depths less than 4' MLW.
3) Dune construction will not occur in the Inlet Hazard Area AEC Zone (beach stations 0+00 to
17+50.)
4) New Topsail Inlet channel widths will remain at the previously permitted 150' wide from its
confluence with Topsail Creek and the inlet throat. From the inlet throat through the offshore
ebb shoal, the inlet will be 500' wide.
5) The cut through channel layout has been completely changed since the original application was
submitted. An extensive PNA has been delineated across much of the flood shoal of New Topsail
Inlet. Regulations prohibit new dredging within a PNA unless it occurs in an established and
continuously used channel. As such, the location and dimensions of the cut through channel
have been relocated to a naturally occurring channel that currently resides within the flood
shoal. The width of the cut through channel has been reduced to 200' wide and the depth
remains at 16+2' MLW. A very small portion (240') of the cut through channel passes through
the PNA boundaries. Within this area, the dimensions are reduced to that of the channel that
was dredged in 2010 (150' wide and 8+2' MLW depth).
6) In an effort to avoid foraging habitat for shorebirds, ie. Red Knot and Piping Plover, the Topsail
Creek and New Topsail Inlet Channels have been adjusted slightly to follow the naturally deep
water surrounding the flood shoal. The dredge toes will not impact the existing marsh and the
channel alignments now avoid as much emergent low tide shoals as possible.
Channel Summary
As mentioned above, as we have progressed through the permitting process some of the proposed
dredge channels have been modified to minimize environmental impacts. Topsail Creek, New Topsail
Inlet and the Cut Through Channel have all been shifted and the dimensions of New Topsail Inlet and the

Cut Through Channel have been modified. The proposed dredge areas and dimensions of Banks
Connector Channel, Banks Channel, Banks Side Channel 1 and Banks Side Channel 2 have not changed
since the original permit application. The table below summarizes the most up to date channel
dimensions, lengths, and depths.

Geotechnicat Analysis
In conjunction with modifying the proposed dredge channel alignments, the underlying geotechnical
information must be updated. The total volume to be dredged within each channel changes as the
dredge area is shifted and the vibracores that represent the dredged material may change as well. The
original spider map was used to re calculate the volume of material each stratigraphic layer of sediment
represents. As discussed in the original geotechnical report, the polygons for the spider map are
developed based upon the spatia( relationship between adjacent cores—each side of the polygon
represents the exact midpoint between adjacent vibracores. Once created, the individual polygon is
copied vertically downward to represent individual layers that exist in the core, emulating the
stratigraphic conditions of the sediment that were established during the core logging. Each individual
stratigraphic section shown in the core logs is represented by an independent layer in our volume
program. The total volume of each stratigraphic layer within the proposed channel design is calculated
using Trimble Terramodel and multiplied by the grain size statistics of the layer's representative sample.
Because of varying initial sample sizes, the weight retained on each sieve is converted to a percent of
the total sample retained to normalize the values. For example, if a one sample had an initial weight of
225 grams and another had an initially weight of 205 grams, the weight retained on each sieve would
not be comparable between the two. To alleviate this issue, the values are converted to percent
retained to equilibrate the samples. The total volume represented by the sample is multiplied by the
individual percent retained on each sieve to create a weighted value for each sample. The weighted
sediment statistics are then combined in a comprehensive spreadsheet and averaged for the entire
channel length and volume, resulting in the weighted average sediment statistics for each individual

dredge area. Finally, the individual channel statistics are combined to generate the weighted average
values for the entire channel system as a whole and are compared to the native grain size statistics for
Topsail Beach.
As channels have been modified during the permitting process, the overall geotechnical analysis has to
be updated to reflect these changes in channel location and volume dredged. Geotechnical
spreadsheets are attached to this document to show the updated statistics for each individual channel
that has been modified as well as an updated analysis of the channel system as a whole with the
updated dredge volumes. As the material within the channels is of good quality, the channel alignment
modifications do not have negative implications towards sediment compatibility. The proposed dredge
sand remains a close match to the Topsail Beach native grain size statistics and is a good source for
beach nourishment. The table below summarizes the grain size statistics for each channel and how they
relate to the native beach sand as well as the CRC Sediment Criteria thresholds.

Topsail Channel Dredging and Renourishment Project 2018-2019
A major modification to the Town of Topsail Beach's permit (CAMA # 22-09 and USACE Action ID SAW -2013-
00404) was submitted in January 2018. Since the original submission, the channel alignments have been
modified. Due to the relocation of the Cut -Through Channel, an additional vibracore was needed to fulfill the
requirements of core spacing as defined by the NC Sediment Criteria Rules.
This additional core was collected by Athena Technologies on July 11, 2018 and the split core was delivered to
TI Coastal Services for analysis on July 13, 2018. The core was photographed and described, samples were
taken to represent the stratigraphic layers found within the core and grain size and calcium carbonate analysis
was completed. These statistics were applied to our weighted average analysis of the overall channel system
and the geotechnical tables were updated with the new data. Please reference the following tables and plots
for updated geotechnical information for the project. Included are:
1. Updated statistical table for all channels and overall composite of channel system.
2. Grain size spreadsheets for composite channels and cut through channel
3. Vibracore spider map showing core locations and area represented by each core
4. Newly acquired Vibracore 66 core log, photographs, grain size curves, and granularmetric tables.
