Re: North Topsail Beach Truck Haul Permit Modification — Phase/Reach 1 Beach Fill
Dear Ms. Coats:
Please allow this letter and submittal to serve as a formal request for a permit modification to CAMA
Permit #79-10 to place beach compatible material along North Topsail Beach (NTB). This proposed will
add sand to the upper, intertidal, and lower beach.
Truck hauled sand is being brought in from an upland borrow source. This project is partially funded by
FEMA and will require competitive bidding and two sand mines (ST Wooten Sand and 421 Sand) have
been included as a sand source in this permit modification request. Both of these mines have been
successfully used for recent Surf City and NTB dune restoration projects and have sufficient material for
this project.
Additional information, including project drawings and additional project descriptions, are attached.
Please let me know of any comments or questions.
Sincerely,
Francis J. Way, PE

Project Description
North Topsail Beach Reach 1 Truck Haul Project Narrative
November 2021
Overview
The Town of North Topsail Beach (NTB) actively manages and maintains its approximate 11 miles
of coastline. NTB is currently completing a dune truck haul project and is currently in permit
processing for a Phase/Reach 5 beach truck haul. These dune and beach projects continue to
provide beach area for habitat, residents, tourists and buffer protection to upland infrastructure.
The past few hurricane seasons have brought several major hurricanes near the NTB coastline
causing extensive erosion with Hurricane Florence (2018) and Dorian (2019). The State and
FEMA have contributed funds to NTB for beach/dune recovery efforts from Hurricane Florence
and Dorian.
Figure 1: Overview of NTB reaches/phases of shoreline.
North Topsail Beach has 5 reaches (also referred to as phases) of shoreline, beginning at
Phase/Reach 1 along the New River Inlet at the north, down to Phase/Reach 5 which terminates
at the Surf City border (see Figure 1).
Project Purpose
The purpose of the proposed project is to provide much needed sand to the Reach 1 section of
beach along North Topsail Beach. This sand will be placed on the upper, intertidal and lower
beach (no dune placement is proposed). North Topsail Beach, along with a large portion of the
1
North Carolina shore, have been subject to several major hurricanes over the last few hurricane
seasons. These major hurricanes bring high tides and energetic seas that quickly erode beach
berms and dunes and leave upland infrastructure vulnerable. The Town of North Topsail beach
plans to renourish this section of Reach 1 to provide protection to the existing dunes, upland, and
infrastructure adjacent to the beach. Note that this placement of material will be along shoreline
that is outside of the USFWS CBRA (or COBRA) zone (although material can be placed within
COBRA zones).
Project Description
The proposed project includes excavating sand from an existing permitted upland sand mine
(sand mine details are attached) and trucking sand via dump trucks from the mine to the beach.
Sand will be placed on the beach in a staging area by the dump trucks, loaded on an off -road
dump truck by excavator, and then trucked from the beach access to the appropriate dumping
locations. The sand will then be spread and graded to match lines shown on the attached plans
by a combination of bull dozers and front-end loaders. This is the same general activity that the
town has performed the last two years (during the winter/spring environmental window).
The transfer of sand from the on -road dump truck to the off -road dump trump will occur on the
upper beach at the beach access. This is to ensure no incompatible materials are introduced
during the sand transfer.
The Reach 1 template starts at 2174 New River Inlet Road and continues to 2330 New River Inlet.
The template will be accessed through the existing beach access at -1300 New River Inlet Road
(Jenkins Way access) or possibly an access at the Topsail Reef Villas (which begin at 2174 New
River Inlet Road). The proposed berm elevation ranges between +3 and +6-foot NAVD88 with a
1 VAH seaward slope. The berm width is 90-150 feet wide, stretches -2,175 feet along the beach,
and requires an average of -18 cy/ft of material.
The trucking operations will utilize major roads during hauling and the off -road trucks will avoid
existing dunes and vegetation. No dune or dune vegetation modifications are planned, and only
existing beach accesses will be used (although there are some locations within the Topsail Reef
Villas that may also allow for access without disturbing existing vegetation). Sand placed in the
beach berm will not cover any existing vegetation or sandbags.
Table 1 presents a list of the project characteristics for each Reach 1.

For planning and permitting purposes, some additional volume is proposed to account for the
recent nor'easter under king tide conditions in early November as well as any future erosion. A
total project volume of 45,000 cy is proposed.
Project Timing
The project is planned to occur during the winter environmental window (i.e., outside of turtle
nesting season). The Reach 1 project is proposed to occur during the in March and April 2022
as this element of the project is much smaller and should be completed in less than 6 weeks.
Project Permit Drawings
Project permit drawings are attached to the end of this document in Appendix B.
The attached set of construction plans includes bathymetric and topographic data from June
2021. The mean high water (MHW) and mean low water (MLW) lines are based on elevations
gathered during the July 2021 survey effort. Note that sandbags were also surveyed in August
2021.

Truck Beach Access
One beach access is identified for the project although the Town may attempt to use an area
within the Topsail Reef Villas condominium property. The stockpile and rehandling area is
required to transfer the truck -hauled material to all -wheel -drive dump trucks that travel on the
beach. The transfer will occur on the beach to ensure material quality. Excavators and other
heavy equipment will load the all -wheel -drive dump trucks. Dozers and similar heavy equipment
will shape and construct the beach berm.
Coordination with NTB public works will occur to ensure minimal disturbance at the beach access.
Truck beach access will be restored to original conditions following project completion if
necessary. This impact area is conservatively estimated at 0.1 acres, though the area will likely
require no modifications for use as they are actively used by town safety and emergency vehicles.

Figure 2: Existing public beach access known as 'Jenkins Way" is the primary beach access. This access was used for recent dune
truck haul placement from the Topsail Reef Villas to the pier.
Figure 2 presents an overview of the Jenkins Way existing public beach access. Once transferred
to all -wheel drive beach dumptrucks, the all -wheel drive dumptrucks will travel approximately 1.9
miles to the project site in front of the Topsail Reef Villas condominiums.
Figures 3 and 4 present potential beach accesses at the Topsail Reef Villas. These would require
additional coordination with the Topsail Reef Villas but these accesses would reduce beach
driving and these potential accesses have little to no dune vegetation. Heavy equipment is shown
at the Figure 4 potential access. Care would be needed to not disturb or damage the existing
sandbags for these potential accesses.

Figure 4: Another potential access at Topsail Reef Villas which heavy machinery already uses (this access between units 1 and 2
on the north end of the Villas). Some additional coordination with Topsail Reef Villas would be required.
Pre -submittal Scoping Meeting
An interagency pre -submittal scoping meeting was hosted by NCDEQ on September 13, 2021,
to discuss the project prior to application submittal.

Florence & Dorian FEMA Mitigation
The Reach 1 template has qualified for FEMA Hurricane Dorian "Category G" damages of 15,007
cy. Therefore only a portion of the proposed total volume to be placed. The remaining volume
will be financed by others (e.g., Town, State Grant, HOAs)
Inlet Hazard Area (IHA)
The project is currently partially within the current IHA while it is entirely within the "pending" IHA
(yellow in Figure 5). No dune construction/rehabilitation is proposed for the project.

Project Permit
The DCM permit modification is for 79-10. This permit was most recently used for the 2020/2021
dune truck haul project. The proposed project will have no dune feature and only proposes to
place sand on the upper, intertidal, and lower beach.
Upland Sand Source
Two upland sand mines have been identified for the proposed project. Both sand mines have
successfully been used for Surf City and NTB truck haul projects and these mines are:
1. ST Wooten
2. 421 Sand
Information on both sites is provided in the following sections. Both upland mines provide
processed sand to mix for concrete, asphalt, and mortar. Processed sand is sand that is
hydraulically dredged at the mine and run through a classifier. This sand is referred to as "washed
and processed" as a result and is very uniform with very few fines and gravel. The clean and
well sorted sand is essential for successful large-scale construction projects. This product is also
ideal beach sand as a result of the washing and processing.
Sand is dried via stockpiling/air drying at the mine prior to loading and trucking offsite. Similar to
the previous permit modification, material will be screened at the borrow area prior to hauling to
the project site. All material dredged for use on the beach will be screened with a %" screen at
the sand mine site.
Both sites have been contacted about the project and both sites have confirmed that they have
enough material for the proposed project and that this is the same material that was used for
previous Surf City and NTB dune projects. Both sites have ample volumes available for the
proposed project (45,000 cy) even when accounting for the separate truck haul efforts (dune
project, etc.) and other sand clients. However they do like to have some lead time (ideally a few
months) to stockpile enough sand to keep up with production during active truck hauling.
Sand Compatibility
Table 3 presents summary compatibility for the native beach as well as the two sand mines. This
data was sourced from the NTB 2009 EIS (for native beach characteristics) and the NTB and Surf
City permit modification requests/projects (for the project sand). Additional sediment data from
the recently placed sand haul projects is also available and can be provided upon request
(although this data has been previously submitted to DCM during project construction). Both sand
mines are compatible with native beach sand based on DCM sediment criteria thresholds.
Sediment granulometric data is provided at the end of this document from both mines.

been provided to DCM.
Sand Availability
Both ST Wooten and 421 Sand have significant sand available at their active mines. Greater
than 2 million cubic yards (cy) is available at each mine. ATM staff have contacted both mines
to ensure that existing mines have adequate material for the proposed project.
Sand Mine Information
Sand mine information for 421 Sand and ST Wooten is provided below.
421 Sand Mine
The 421 Sand mine is located at 5401 Highway 421 in Wilmington, NC. Mr. Dennis Earp is the
plant manager and can be reached at:

Figure 6 presents the location of the 412 Sand Mine.
Figure 6: 421 Sand mine location
A small Ellicott Dredge sits in the sand pit borrow area excavating material via cutter suction.
Sand is initially screened by a 3/8" mesh and any material coarser than 3/8" is kicked out to a
discard pile. Any material passing the initial screening is then classified in a tank where it is
washed for fines and separated based upon grain size. The plant carries two main, screened
sand sizes, 2S (asphalt and concrete sand) and 4S (mortar sand). TI Coastal's geotechnical lab
has sampled 421 Sand on multiple occastion. The average grain size for the 2S sand was 0.5
mm and the 4S sand was 0.33 mm.
The screening process effectively removed all large pebbles and stones as well as vegetative
debris. Because the material is dredged and then washed in the sieving process, all fines (passing
the 230 sieve or less than 0.0625 mm) have been removed from the final product. The onsite
stockpiles consist of a mix of the 2S and 4S graded sands with a combined average grain size of
0.41 mm and 0.0% calcium carbonates. Munsell colors of the 421 Sand were 10YR 7/3 (wet) and
10YR 8/2 (dry) (source, TI Coastal).

ST WOOTEN
The ST Wooten site is located at 226 Sutton Lake Road near Highway 140. Figure 7 presents
the location of ST Wooten.

The ST Wooten sand processing is very similar to that of the 421 Sand site as both of these mines
are in similar locations and serve the same clients and industries. Note that extensive
geotechnical testing and gradation analyses were conducted to determine the Fineness Modulus
(FM) of the material. Of course this geotechnical analysis was for the in -situ material and not the
final processed sand used for the dune restoration.
