8. PROJECT SUMMARY: The applicant proposes to perform maintenance excavation of an
existing canal connecting a public boat ramp to the Croatan Sound.
Project Setting
The proposed development site is a canal on Dare County property located at the end of
Bowsertown Road (SR 1131) near the intersection with California Lane (SR 1345), on Roanoke
Island. The property is approximately 100 acres in size. Approximately 70% of the property is a
Coastal Wetland Marsh that is vegetated with Juncus roemerianus. The wetland area is located on
the western side of the property and is adjacent to the Croatan Sound. The upland area of the
property is developed as a solid waste transfer site for Dare County located on the northeast side
and a NCWRC boat ramp and parking area located on the southeast side. The solid waste transfer
site was once the County Landfill. Vegetation in the upland areas consists of pines and indigenous
grasses and the soils in this area are a sand, sand loam type.
The existing canal is approximately 2,500 feet long and 50 feet wide with a controlling water depth
of -1.7 feet and an average water depth of -3.2 feet below NWL in the center, of the canal. The
shoreline of the canal in wetland area consists of Juncus on the south side and a spoil ridge along
the north shoreline with Juncus behind the spoil ridge. The shoreline of the canal in the upland
area is a pine forest on the south side and the landfill area on the north side.
The canal connects to a natural waterway that connects to the Croatan Sound. The waterway is
approximately 1,800 feet long with a width that varies from 60 feet to 120 feet and has a
controlling water depth of -1.5 feet and an average water depth of -3 feet below NWL in the center
of the fairway. NCWRC hazard buoys are located along this waterway. The shoreline along the
waterway is Juncus. The water depths in the Croatan Sound near the project area are
approximately -5 feet below NWL. The bottom material in the project area consists of muck
material with some sand in the areas nearer to the Croatan Sound.
The adjacent properties are undeveloped salt marsh tracts. The waters of the Croatan Sound are
classified as SA in this area and the area is closed to shellfish taking. No submerged aquatic
vegetation was observed at the proposed work site.
Development Proposal
In order to improve boating access, the applicant proposes to excavate the Bowsertown Canal and
waterway to a controlling water depth of -6 feet (5'+ l' OD) below NWL. The activity will be
performed by an excavator on a barge and excavated material will be placed on another barge and
brought to the old landfill site to be unloaded. The material will be deposited at the site on a 1.45-
acre area that will be surrounded by silt fence.
F
The proposed maintenance excavation will remove approximately 13,800 cubic yards of bottom
material and storm debris. In the canal, the proposal is for a 16-foot wide channel for the upper
area and a 20-foot wide channel for the rest of the canal and waterway.
Field Investigation Report: Dare County, Bowsertown Canal

Antichwed Impacts
The development proposal with result in approximately 62,400 square feet of Public Trust Area
(PTA), Estuarine Waters (EW) Areas of Environmental Concern (AECs) being excavated in the
canal and approximately 57,000 square feet of PTA, EW AECs being excavated in the waterway
connecting to the Croatan Sound. Sidewall excavation is included with each figure.
The proposed unloading site will result in approximately 1,750 square feet of Estuarine Shoreline
AEC being disturbed and the proposed spoil site will involve approximately- 1.45 acres of uplands.
Temporary water turbidity will occur during the excavation of the canal and use of the boat ramp
will be restricted.
An Environmental Assessment of this project was circulated with a Finding of No Significant
Impact issued on April 14, 2006.'

Bowsertown Canal Dredging Project = t t , , _
Dare County, North Carolina
Introduction
The Dare County Oregon Inlet & Waterways Commission is a county appointed board
that, among other things, monitors the condition and depths of local public access
waterways and facilitates the periodic maintenance dredging of these waterways when
required. The Bowsertown Canal is a public access waterway that is located on the
western side of Roanoke Island within unincorporated Dare County near the town of
Manteo. The eastern end of the canal is located near the intersection of Bowsertown
Road and California Lane and the canal extends toward the west for a distance of
approximately 4,200 feet where it opens into the Croatan Sound. The canal varies in
width from about 40 to 50 feet at the eastern end to approximately 150 feet at the western
end.
The canal was constructed many years ago as a "mosquito ditch" and subsequently was
used as an access channel for small watercraft. About 15 years ago, the Wildlife
Resources Commission in conjunction with Dare County constructed two boat ramps and
a large parking area on the southern side of the canal at its eastern end. This facility is
frequently utilized by both commercial and recreational watercraft. In recent years,
however, use of the canal has become somewhat limited during low tide conditions. A
recent survey indicates that some areas of the canal are less than three (3) feet deep,
measured from mean low water.
The Dare County Oregon Inlet & Waterways Commission is proposing to perform
maintenance dredging of the canal. We are proposing to mechanically excavate at least
8,500 cubic yards of material from the canal and place it at the old Dare County Landfill
and Transfer Station site located just north of the canal. The following sections briefly
describe the details of the project and the methods that we are proposing to accomplish
the project.
Boat Channel
A review of the information that we have pertaining to this canal does not reveal a history
of maintenance dredging. The only information we do have indicates that the original
mosquito ditch was excavated during the 1950's or very early 1960's. At this time, the
straight portion of the canal (approximate Station 18+00 to Station 44+00) was excavated
in order to "improve" drainage, as was typically done within many coastal marshes
throughout the area. During the 1970's, this straight portion of the canal was re-
excavated in order to mine sand to use as a foundation for the new landfill under
construction at the east end of the canal. It appears as if the material was excavated from
the north side of the canal and was placed along the canal edge to construct a haul road.
Once this road was completed (or as it was being constructed), additional material was
removed from the canal and was hauled to the new landfill area. At the completion of all
of this work, the haul road remained in place along the north side of the canal. This
upland area averages about 4 feet above the water level, has a width ranging from 30 to
50 feet, and is fully vegetated with upland species. It would be my estimation that the
canal was excavated fairly deep in order to obtain as much material as possible for the
landfill.
Based upon the fact that no formal channel alignment presently exists, a channel has been
designed using the information obtained from a hydrographic survey performed in March
2005 (see project drawings). The channel has been positioned in the naturally deepest
portions of the canal in order to minimize the volume of excavation. The project
drawings show the channel dimensions and alignment. The channel will have a bottom
width of 20 feet from Station 0+00 to 25+02 and a width of 16 feet from Station 25+02 to
43+42. The depth of the channel will be at least 5 feet below mean low water (MLW)
and the sideslopes will be 3:1 (3 horizontal to 1 vertical). The channel has been designed
to ensure a minimum separation of ten (10) feet between excavation of the bottom and
the edge of the coastal marsh. As can be noted from the drawings, the bottom depths at
the mouth of the canal in the vicinity of station 0+00 are approximately 8 feet. The
quantity to be removed based upon the March 2005 conditional survey is about 8,500
cubic yards to the grade depth of 5 feet. To obtain one foot of overdepth would require
the dredging of an additional 5,300 cubic yards, or a total of about 13,800 cubic yards.
The total bottom area to be disturbed with this project is estimated to be approximately
168,000 square feet.
During the winter of 2005, three bottom samples from the canal were obtained in order to
determine the general character of the material to be excavated. The samples were
obtained using a hand auger manually deployed over the side of a small skiff. In each
case, a surface sample was obtained and visual observations of the material were
performed. In addition, the hand auger was used to determine the consistency of the
underlying materials by pushing the auger down into the bottom. Samples in the vicinity
of station 33+00 and 18+00 consisted primarily of very soft, silty mud with varying
organic contents. A sample in the vicinity of station 3+00 yielded a very similar material,
however, a slight amount of fine sand was observed. At all three locations, the auger was
easily pushed to a depth of at least 2 feet below the bottom surface indicating very soft
underlying materials. Throughout the channel from Station 19+00 to 42+00, we
observed some scattered woody debris consisting of tree trunks, tree branches, and root
i
wads that are either along the edge of the canal or are slightly lodged into the bottom.
We also observed a fair amount of man-made trash and debris located along the canal
banks and on the bottom. Items observed include plastic sheeting, cardboard, metal cans,
scraps of fabric, abandoned crab pots, and other household garbage.
Method of Excavation
We plan to mechanically excavate the material from the channel limits and transport it to
the old Dare County landfill located north of the canal. We anticipate that an excavator
mounted on a small barge will be used to remove the material from the bottom. The
material will be loaded onto small deck barges equipped with containers or perimeter
bulkheads in order to prevent spillage of sediments back into the canal. Small scow
barges may also be used to transport the dredged material. It is anticipated that at least
two of these barges will be necessary in order to ensure an efficient work cycle. The
excavator barge will be equipped with spuds that will be used to secure the barge in
position during a digging set. These spuds will be raised and lowered by either using the
excavator or by hydraulic powered winches. An additional excavator will be positioned
on the north side of the canal in the area labeled "unloading area" on the project plans.
This excavator will be used to unload the material barges and place the dredge spoil into
dump trucks. The dump trucks will haul the material to the designated location at the
northwestern corner of the landfill.
We also plan to install silt curtains on both the "upstream" and "downstream" side of the
unloader and on the Sound side of the excavator barge in order to minimize the amount of
turbidity entering the Sound. These curtains will be placed across the canal and will be
opened and closed each time a barge or boat transits the canal.
We anticipate that it will take two to three (2-3) months to complete this project.
Disposal Area
The Dare County Landfill was used for many years as a sanitary landfill that served most
of the northern portion of the county. In 1981, a garbage transfer station was constructed
on the same site so that all sanitary waste could be transported to other landfills. In
March 1982, the landfill was closed to further burial of household garbage and the
transfer station began operations (please note that construction and demolition (C&D)
debris continued to be disposed of at this site until 1990). At the present time, the surface
of the old landfill is used as a staging area for the drop-off, !sorting, and loading of
recyclable metals. The building at the eastern end of the property near the road continues
to serve as a solid waste transfer station.
As mentioned above, we anticipate that all of the dredged material will be placed within
the designated spoil area at the northwest corner of the landfill. As the drawings indicate,
a wire reinforced silt fence will be installed around the entire perimeter of the spoil area
to minimize, or eliminate, any oil site impacts. The material will be truck-hauled the
short distance from the barge unloading area to the spoil site where it will be dumped
onto the ground. An existing haul road within the landfill will be used - no additional
roadways will be constructed. The material will be unloaded into a single layer ranging
from 4 to 6 feet in depth. If additional space is needed within the disposal area as it is
being filled, the dewatered material may be re-excavated and placed into a higher pile.
The height of the spoil material, in any case, will be minimized in order to lessen the
potential for erosion. At the completion of disposal operations, the spoil pile will be
seeded with appropriate plant species in accordance with the approved Erosion and
Sedimentation Control Plan and Permit. It is noted that no other upland activities are
proposed for this project (i.e. no areas of impervious are to be constructed as a part of this
project) other than the above described temporary stockpiling of dredged material.
It is worthwhile to note that a new Transfer Station is presently being constructed near
Mann's Harbor on the Dare County "mainland." This new facility is scheduled to begin
operations this year. Once the new facility is completed, the existing transfer station will
be closed and removed and all "public works" activities on this site (garbage transfer,
metal recycling, etc.) will cease. Presently, a local effort is underway to redevelop this
site into a recreational area once the station is removed. We believe that the spoil
material will be an asset to this redevelopment project since, if mixed with more sandy
soils, it would be ideal for use as a topsoil or growing medium.
In an effort to move forward with this redevelopment project, a preliminary toxicological
study of the landfill and the surrounding tidal waters was performed during this past
spring. This study was sponsored by Dare County, the UNC Coastal Studies Institute,
and the Manteo Rotary Club. The project was funded by Dare County and through a
grant from the Division of Water Resources, NCDENR. The Department of
Environmental and Molecular Toxicology at North Carolina State University performed
the study. Water and sediment samples were obtained from the canals on the north,
south, and west sides of the landfill and were tested for a number of items, including
heavy metals, PCB's, pesticides, hydrocarbons, and volatile organic chemicals. The
preliminary information that is included in the draft report indicates that there are no
elevated levels of contamination that would cause this project not to move forward.
