I. PROJECT DETAIL AND HISTORY
Site Location
The 32-acre site is located approximately 2,300 feet southeast of the intersection of Erza
Moore Road and Bay Road in Teachey, Duplin County, North Carolina (Figure 1A). The
site is also situated approximately 2,300 feet north of High School Road. The site is
bounded on the east by Interstate 40 and on the south and west by wooded land. There
are two points of access to the site. An unpaved access road extends southeast from Bay
Road (Access Road 1), and north from Highschool Road (Access Road 2), towards the
site. An approximate 100-foot wide overhead electrical easement traverses the site from
north to south. Duke Energy maintains the easement and routinely navigates service
equipment/vehicles along the easement corridor.
The site is comprised of three parcels. Grey Outdoors, LLC owns Parcel 09-3160 (9.35
acres) and Parcel 09-1813-1 (9.61 acres). The Willoughby-Townsend, LLC owns Parcel
09-7000 (36.4 acres). The site includes all of Parcel 09-3160 (Tract 1) and Parcel 09-
1813-1 (Tract 3), and a portion of Parcel 09-7000 (Tract 2). The area west of the electrical
easement along Tract 2 is excluded from this assessment.
Grey Outdoors, LLC currently has plans to purchase Tract 2 from The Willoughby-
Townsend, LLC.
Purpose/Proposed Plans
Grey Outdoors, LLC intends to develop eight billboards along the eastern site boundary,
abutting Interstate 40. Each billboard will be supported with three 3-foot diameter pilings.
Temporary and permanent access roads will be utilized to construct the billboards. The
billboards shall be situated approximately 500 feet apart.
The previous owner of Tract 3 (Corbett Industries, Inc.) has retained timber rights to said
parcel of land. It is our understanding The Willoughby-Townsend, LLC shall retain timber
rights to Tract 2. Therefore, the future clearing of Tracts 2 and 3 are not associated with
the construction of the billboards.
Impacts to Waters of the U.S.
In June/July 2018, Grey Outdoors, LLC retained a clearing/grading contractor to begin
removing vegetation and constructing the lateral access road to the northern most
proposed billboard. Construction of the lateral access road began at the southern terminus
of Access Road 1. Additionally, a ditch was excavated parallel to the access road. An
excavator was utilized to excavate the ditch. The dredged material was sidecast parallel
to the ditch to create the lateral access road. Off-site material was not utilized to construct
the lateral access road during the construction efforts.
A “skid area” was created on the southern portion of Tract 1 and northern portion of Tract
2. The blade of a bulldozer was used to push the upper layer of soil and organic debris to
create the skid area. The lateral access road, ditch, dredged material, and skid area all
transect jurisdictional wetlands. There are no streams within the site boundary.
Headwater Project #201816

At the time, the wetlands had not been delineated by a consultant, nor verified by U.S.
Army Corps of Engineers (USACE). In July 2018, the USACE observed the wetland
impacts via Interstate 40. Mr. Tom Charles of the USACE performed a site visit with Mr.
Grey Vick in July 2018. Mr. Charles confirmed the construction activity occurred in
jurisdictional wetlands. It is our understanding Mr. Vick verbally agreed to restore the
wetlands and submit a permit application for the billboard construction project. A violation
letter was not issued by the USACE.
II. DELINEATION OF WETLANDS, EXCAVATION, AND FILL
Methodology
In addition to performing a routine wetland delineation, the purpose of the site
reconnaissance was to map, locate, and document the extent of wetland impacts. Fill
material and areas of excavation were visually observed. A hand auger was used to
determine the depth of fill material.
In order to identify wetlands, Headwater utilized the “Regional Supplement to the Corps
of Engineers Wetland Delineation Manual: Atlantic and Gulf Coastal Plain Region”, issued
November 2010. The field reconnaissance involved a general site inspection, wetland
observations, and a wetland boundary delineation. The purpose of the site
reconnaissance was to verify the published data, inspect the site for the presence of
wetlands, and delineate (flag) the wetland/upland boundaries. Headwater utilized the
Trimble Geo7x GPS device to locate and map the wetland features.
During the field review, examination of wetland characteristics was conducted. Data Points
were established and are attached to this report. The Data Points were used to record
field data on vegetation, soils, and hydrology. Information collected at each data point
includes the following:
Characterization of Vegetation
Vegetation at each Data Point was characterized as per the appropriate regional
supplement to the USACE Wetland Delineation Manual for the following stratum
(layer):
A. Trees: Woody plants, excluding vines, approximately 20 feet or more in
height and three inches or larger in diameter at breast height (DBH).
B. Saplings: Woody plants, excluding vines, 20 feet or more in height and
less than 3 inches DBH.
C. Shrubs: Woody plants approximately 3 to 20 feet in height.
D. Herbs: All, non-woody, herbaceous plants less than 3 feet in height.
E. Vines: All woody vines, regardless of length or height.
Soil Characterization
Soil characteristics at each data point were reviewed with the use of a 2-inch
diameter Dutch auger. Soil samples were obtained from the ground surface to the
depth necessary to identify hydric soil characteristics. The matrix color of each
sample was identified and recorded using the standard Munsell Soil Color Chart.
Other soil characteristics (i.e.: textures, concretions, structure) of each sample
Headwater Project #201816
August 5, 2019

were also examined and recorded. Particular emphasis was placed on the
identification of (or lack of) certain hydric soil indicators such as low chroma and/or
mottled soils.
Hydrology
Each data point was examined for evidence of surface and subsurface hydrology.
Field indicators (i.e.: water stained leaves, oxidized root channels, morphological
plant adaptations, etc.) were identified and recorded. Each point was evaluated for
primary and secondary indications of wetlands hydrology.
Site Reconnaissance
Headwater personnel conducted the initial site reconnaissance on August 22, 2018. The
initial site reconnaissance was concentrated on Tract 1 and northern portion of Tract 2
(i.e. the area associated with wetland impacts). A second site visit was conducted on
February 2, 2019. The purpose of the second site visit was to complete a wetland
delineation on the remainder of Tracts 2 and 3. Headwater utilized the Trimble Geo7x to
map and locate jurisdictional wetlands and associated impacts (Figures 1B and 1C).
The majority of the site is a jurisdictional wetland. All of Tract 3 is comprised of a managed
pine flat wetland. Headwater identified four upland “islands” throughout Tracts 1 and 2
(Figure 1B). Although hydrophytic vegetation and saturated soils were observed, the
upland islands have non-hydric soils.
The soils in the wetland areas have low chroma and low value colors. The wetlands areas
are dominated by hydrophytic vegetation and exhibit wetland hydrology indicators. The
majority of the wetland is classified as a pine flat wetland. The pine trees become less
dominant in areas of lower elevation; these low areas are classified as a hardwood flat
wetland. The wetland appears to be seasonally saturated and inundated. Multiple areas
of ponding and inundation were present during the August and February site visits. The
ponded areas are void of vegetation. The wetland areas along the electrical easement are
routinely maintained by Duke Energy and are classified as palustrine emergent wetlands.
Refer to Figure 1C for a depiction of wetland types and wetland impacts.
A common feature in seasonally inundated hardwood flat wetlands are hummock mounds.
A hummock is a small knoll or mound above the grounds’ surface. In the coastal plain of
North Carolina hummocks are comprised of mucky peat material, soil, and living plants.
These wetland hummocks were observed within the intact wetlands, adjacent to the
excavation/skid areas.
Data Point 1 (DP-1), DP-2, DP-4, DP-D were collected in a wetland. DP-3, DP-A, DP-B,
and DP-C were recorded in an upland. Headwater marked the wetland boundaries with
pink surveyor tape. The wetland labeling scheme is included on Table 1.
Table 1. Wetland and stream labeling scheme.

wetlands. Headwater traversed the perimeter boundaries and made several transects
across the interior of the site. We used hip waders to traverse the ponded areas.
Headwater did not observe additional surface waters or wetlands on the site. In addition
to wetland impacts, Figures 7 shows the approximate locations of the wetlands, flags, and
data points.
Soil Borings
In order to determine the depth of fill material placed within the jurisdictional wetlands,
Headwater advanced 11 borings throughout Tract 1 and northern portion of Tract 2
(Figure 1D). The depth of fill ranged from eight to 17 inches. Our boring log and
photographs are saved in Appendix B.
III. RESTORATION PLAN
Methodology
The restoration efforts shall be performed in conjunction with the construction of the
proposed billboards. Detailed site plans are included with the permit application.
Equipment to be used will include earth moving equipment, such as, a mini-excavator and
bulldozer. After construction of the two northernmost billboards, the temporary access
road will be removed, and wetland
conditions restored. A permit application will
be submitted for the billboards on the
southern portion of the site.
Fill Areas
Grade stakes will be placed at each boring
location. The depth of fill will be marked with
red spray paint and the natural grade depth
will be marked with green spray paint. The
red and green markings will provide the
equipment operator a visual queue to the
natural grade elevation. The fill material be
removed and placed in the adjacent ditch,
from which the material originated (Figure
2A).
Skid/Excavation Areas
The uppermost layer of soil and hummock
mounds were mechanically removed from
the jurisdictional wetland. In order to restore
the jurisdictional wetlands to their previous state, root mats and dense woody material will
be selected from the adjacent debris pile and placed in the skid/excavation area. The
constructed hummock mounds shall be three to six feet in diameter and placed six to eight
feet apart (Figure 2B).
Headwater Project #201816
August 5, 2019
5
Organic Debris Piles
The remainder of the organic debris piles that are not used for creating hummock mounds
shall be removed from the jurisdictional wetlands and placed at an on-site upland staging
area.
Planting Schedule
Headwater has elected to allow the native seedbank to replant the site. The adjacent intact
wetlands are comprised of dense thickets of galberry (Ilex coriacea), ink berry (Ilex glabra),
Carolina ti-ti (Cyrilla racimaflora), laurel greenbriar (Smilax laurifolia), water tupelo (Nyssa
aquatica), red maple (Acer rubrum), and coastal dog hobble (Leucothoe axillaris).
Herbaceous species in the electrical easement included Carolina redroot (Lachnathes
caroliniana), soft rush (Juncus effusus), switch grass, tufted bulrush (Trichphorum
cespitosum), switch cane (Arundinaria tecta), and others. These native species are
aggressive by nature and will likely out compete any planted varieties.
Monitoring
Upon completion of restoration activity, photo-documentation will be provided to USCE.
The photo-locations will be consistent with the photographs included with this Restoration
Plan.
