Executive Summary/ Project Abstract
The Bishop Road Wetland Mitigation Site, hereinafter referred to as the Bishop Road Site or Project Site,
is one of a group of sites purchased by the NC Department of Transportation ( NCDOT) to meet its on-
going mitigation needs throughout North Carolina. The Bishop Road Site was purchased in the spring of
2001 from Weyerhauser Corporation. According to Weyerhauser, this and many nearby tracts were
being managed for silvicultural uses. NCDOT worked with a consultant to complete the original Wetland
Mitigation Plan in 2004, a document that described existing and proposed conditions. In 2006, the
Project Site was turned over to the NC Department of Environment and Natural Resources, Ecosystem
Enhancement Program (EEP) for project implementation. During this time period, EEP contracted with
the same consultant to update the document into a Restoration Plan. Once the document was
approved, final design, quantity estimates, construction bidding and implementation proceeded.
Construction was completed during the spring of 2009.
Ecological Engineering, LLP (Ecological Engineering) entered into contract with EEP in October 2009. As
part of this contract, Ecological Engineering was tasked to provide annual monitoring services including,
but not limited to annual vegetation assessments within the existing nine vegetation plots and the
downloading of monitoring well data at 12 locations. During 2010, Ecological Engineering added three
additional vegetation plots to the overall assessment. The downloading of well data occurred
approximately four times during the year. Additional services, including well maintenance and
replacement, were also provided, as necessary.
The Bishop Road Site is situated along SR 1156 (Bishop Road), between US 264 and the Pungo River in
Hyde County, North Carolina (Figure 1). It is approximately one mile north of Scranton, five miles
southeast of Leechville and ten miles east of Belhaven. The Project Site is bordered to the northwest by
Tarklin Creek, the south by Scranton Creek and the west by the Pungo River.
Vegetation Assessment
The Year 2 vegetation monitoring effort was performed by determining density and survival of planted
species, consistent with prescribed Carolina Vegetation Survey (CVS) protocols. Nine 100 - meter2
(wetland) and three 50- meter2 (buffer) plot locations were assessed. Based of survey data, the mean
stem count for all of the plots combined totaled 246 planted stems per acre and 2,567 total stems per
acre. Seven of nine total wetland plots and one of three buffer plots met the 320 -count threshold. Of
the remaining two wetland plots, neither exhibited any stems. The two remaining buffer plots exhibited
counts below the threshold. Supplemental planting was implemented as part of the construction
warranty during early 2010; however, its overall effect did not appear to significantly increase counts as
originally intended.
Wetland Assessment
Wetland assessments associated with the Year 2 monitoring effort were performed by collecting
groundwater hydrology via monitoring wells that record daily groundwater elevations. Based on the
results, all 12 wells met the criteria established for wetland hydrology.

1.0 Project Background
1.1 Project Objectives
Based on information provided in the Bishop Road Wetland Restoration Final As -Built and Monitoring
Baseline Report (EEP, 2009), the project related goals were to restore site hydrology, restore natural
diverse wetland communities and protect the site from vehicle access, logging or development. These
goals were and will be accomplished by the following objectives:
• Remove earthen roads and fill roadside drainage ditches;
• Remove bedding rows in selected areas and replant areas to establish natural plant
communities, non - riparian hardwood flats, coastal marshes and riverine forested wetlands;
and,
• Purchase property fee simple, put under conservation in perpetuity and install vehicle
access barriers.
The system of measurement to determine successful implementation includes documentation of
hydrology through groundwater monitoring wells, documentation of vegetation development through
permanent 100- meter2 plots and documentation of no vehicle access, logging or development through
visual observation (EEP, 2009).
1.2 Project Structure
Mitigation components include coastal marsh restoration and preservation, riverine forested wetland
restoration and preservation, non - riparian hardwood flat restoration and preservation and riparian
buffer restoration. Figure 2 depicts the locations of each mitigation component. Exhibit Table 1 denotes
the final calculated acreages of each component.
According to EEP (2009), the restoration types and amounts were modified during construction due to
plant community nomenclature and inaccuracy of the topographic survey. These modifications deviate
significantly from names and amounts presented in the 2006 Restoration Plan. Approximately 36.0 acres
of non - riparian hardwood flat restoration were removed to reduce construction costs. The tidal
freshwater marsh community is now referred to coastal marsh per the request of EEP and the NC
Division of Coastal Management (DCM). A 2.2 -acre section of tidal freshwater marsh /coastal marsh
located west of Old Bishop Road was changed to non - riparian hardwood flat due to inaccurate survey
elevations. The design was based on topographic survey information provided by a third party. Based on
the survey elevations and its proximity to open water, this area was slated for marsh restoration. After
the area was cleared during construction, it was obvious that the area was significantly higher than the
survey depicted. A small section of non - riparian hardwood flat restoration (0.171 acres) was changed to
riparian buffer restoration. This change resulted from the need of riparian buffer credits in the area
(EEP, 2009).
Vehicle access barriers comprised of concrete Jersey barriers, an earthen berm and a metal gate were
installed at strategic locations within the Project Site.

1.3 Restoration Type and Approach
1.3.1 Coastal Marsh Wetlands
According to EEP (2009), the restoration plan includes 0.343 acres of coastal marsh restoration at two
locations. The first and larger area, covering 0.246 acres, is located at the northern end of Bishop Road
along the main branch of Tarklin Creek. The area consisted of an earthen road bed approximately 32
feet wide and approximately 2.5 feet higher than the adjacent marsh. Restoration was accomplished by
removing the earthen fill to an elevation within ±0.2 feet of the adjacent marsh. The fill material was
used to raise the elevation of the adjacent to the same elevation as the marsh and regraded road. The
restored area was planted with vegetation representative of the adjacent marsh, included black needle
rush (Juncus raemerianus), Sawgrass (Cladium jamaicense), smooth cordgrass (Spartina alterniflora) and
pickerelweed (Pontederia cordata). Soils in the marsh consist of Longshoal mucky peat, a hydric A soil
(EEP, 2009).
The second and smaller area, covering 0.097 acres, is situated near the end of Silverthorne Road.
Silverthorne Road crosses a small tidal slough of Scranton Creek at this location. There was no culvert
under Silverthorne Road at this location. This disconnected the small slough upstream of Silverthorne
Road from tidal flow. Sawgrass (Cladium jamaicense) is the dominant vegetation on the downstream
(the tidal side) of the road. The upstream side was dominated by bare ground. This significant difference
in vegetation is a result of the disconnection from tidal flow. The roadway was removed and graded to
an elevation within ±0.2 feet of the adjacent slough elevations and replanted with the same suite of
coastal marsh herbaceous vegetation as the above location. Soils in the area consist of Bolling loamy
fine sand, a hydric B soil (EEP, 2009).
DCM representative Steve Trowell inspected both coastal marsh restoration areas during construction.
Final construction elevations of the coastal marsh areas were provided to DCM and concurrence was
granted on May 26, 2009.
1.3.2 Non - Riparian Hardwood Flat Wetlands
According to EEP (2009), the non - riparian hardwood flat restoration areas include 56.3 acres of non -
jurisdictional areas within the existing planted pine and roadbed areas throughout the Project Site.
These areas exhibited hydric soils; however, they did not meet the other two parameters necessary for
jurisdictional status. Non - riparian hardwood flat restoration was accomplished by clearing and grubbing
non - jurisdictional 10 to 15 year old loblolly pine plantation then replanting the area with the
appropriate wetland vegetation. The bedding rows were graded to a more natural contour. Existing
roadways were also removed and adjacent ditches were filled with the roadbed material to the
elevation of the adjacent non - riparian hardwood flat community. The depth of cut on the roadways
averages around 1.5 feet. The depth of the adjacent ditches averaged around 2.5 feet. These areas were
also replanted. Soils within the non - riparian hardwood flat restoration areas consist of Acredale silt
loam, Argent loam, Chapanoke silt loam and Yeopin silt loam, all of which are hydric. The Site was
cleared by first removing the pine trees. Trees were cut at the base, leaving the roots in the ground, and
then chipped. The chips were hauled off site. Branches and bark were burned on site. The tree roots
were grubbed using a "rake" attached to a track excavator. This also removed the bedding rows. Root
material was burned on site (EEP, 2009).

1.3.3 Riverine Forested Wetlands
According to EEP (2009), the restoration plan provided restoration of 1.0 acre of riverine forested
wetland. Riverine forested wetlands restoration was accomplished by removing an earthen road bed.
The road material was used to fill drainage ditches adjacent to the roadbed. Target restoration
elevations were designed to be within ± 0.2 feet of the adjacent target community elevations. An initial
survey revealed that the desired elevations had not been met. The contractor was required to re -grade
the area to design specifications. A post construction topographic survey verified that final elevations
were within the target range. Soils within the adjacent riverine wetlands consist of Belhaven muck, a
hydric A soil. Trees removed to accomplish the riverine wetland restoration were a few 10 to 15 year old
loblolly pines located along the ditch banks. After clearing, grubbing and grading, the area was replanted
with riverine wetland species, including bald cypress (Taxodium distichum), water tupelo (Nyssa
aquatica), tag alder (Alnus serrulata) and various oaks (Quercus spp.) (EEP, 2009).
1.4 Location and Setting
The Bishop Road Site is situated along SR 1156 (Bishop Road), between US 264 and the Pungo River in
Hyde County, North Carolina. It is approximately one mile north of Scranton, five miles southeast of
Leechville and ten miles east of Belhaven. The Project Site is bordered to the northwest by Tarklin Creek,
the south by Scranton Creek and the west by the Pungo River. The remainder of the Project Site is
bordered by roads, managed timber areas, agricultural fields and wooded or undeveloped lands.
1.5 Project History and Background
Based on information depicted by EEP (2009), the Bishop Road Site was purchased in the spring of 2001
from Weyerhauser Corporation. According to Weyerhauser, this and many nearby tracts were being
managed for silvicultural uses. The NC Department of Transportation (NCDOT) worked with a consultant
to complete the original Wetland Mitigation Plan in 2004; a document that described existing and
proposed conditions. In 2006, the Project Site was turned over to the NC Department of Environment
and Natural Resources, Ecosystem Enhancement Program (EEP) for project implementation. During this
time period, EEP contracted with the same consultant to update the document into a Restoration Plan.
Once the document was approved, final design, quantity estimates, construction bidding and
implementation proceeded. Construction was completed during the spring of 2009 (EEP, 2009).
Project history and background information is presented in the following four tables. The Final Wetland
Restoration Plan (2006) denotes that the Project Site had been managed for timber since the early
1900's and was initially converted from its original vegetative community to pine plantation by removing
the canopy vegetation. This was accomplished by first harvesting merchantable timber and then using
techniques such as shearing, piling and burning of slash debris. The Project Site has been clear -cut and
planted several times. The timber stands across the site were bedded to keep the roots of the planted
pine seedlings above the water table.

2.0 Project Condition and Monitoring Results
2.1 Vegetation Assessment
Vegetation at the Project Site was assessed by general visual assessments and counting stems within the
nine pre- determined vegetation and three additional plots added in 2010. These plots are randomly
scattered throughout the Project Site and used to determine the approximate stems per acre in and
surrounding the plot location. Their locations are shown on Figure 3. Assessments within each of the
plots were completed using methodology prescribed by the CVS and EEP. Level II assessments were
completed on ten of the 12 plots. The two remaining plots were assessed using Level III assessment
protocol. Appendix A provides the vegetation related data and information including CVS -EEP output
tables and photographic comparisons. Specific information regarding the CVS protocol is presented in
Section 3.0.
2.1.1 Vegetation Problem Areas
Based on the annual field assessment, several vegetation problem areas exist at the Project Site. These
areas are also depicted on Figure 3 and described in the following paragraphs.
For wetland mitigation success, the USACE et. al. (2003) denotes that planted stem counts should be no
less than 320 stems per acre after the third year of monitoring and no less than 260 after Year 5. For
buffer success, the counts must be no less than 320 planted stems per acre after Year 5. Based on the
field data collected during Year 1 monitoring, the annual mean of planted stems at the Project Site was
estimated at approximately 273 stems per acre. EEP utilized the planting contractor's one -year warranty
and a supplemental planting was conducted across several portions of the Site during early 2010. Once
planting was complete, stem counts were updated during Year 2 monitoring activities.
Year 2 monitoring results were slightly lower than Year 1 results for planted stems; however, volunteer
stems significantly increased the overall mean. The means for planted and total were 246 and 2,567
stems per acre, respectively. Seven of nine wetland vegetation plots met the three -year threshold
amount. The two remaining plots (VP# 24 and 25) did not exhibit any living planted stems. This was
likely the result of high water levels throughout the beginning of the growing season. One of the three
buffer plots met the success criteria of 320 planted stems per acre. The data from this plot assumes
approximately 363 planted stems per acre. The remaining two plots exhibited planted stems at densities
ranging from approximately 217 to 290 stems per acre. Exhibit Table V summarizes the vegetation
criteria attainment.
In addition, the two wetland vegetation plots (VP# 24 and 25) did not exhibit any cover during the Year 2
monitoring assessment. Cover was observed however, during the fall and winter months.
According to the NC Drought Management Advisory Council (2010), Hyde County experienced
abnormally dry conditions in May, June, July and September and moderate drought conditions during
August.
Two other problem areas were observed along Old Bishop Road and the area immediately to the west
and an unnamed road that intersects US 264 along the northeastern portion of the Site. Common reed

(Phragmites australis) is present. This invasive species has a tendency to outcompete native vegetation
in wet areas. Controlled burning is the preferred method to control this species.
2.2 Wetland Assessment
Wetland areas at the Project Site were assessed by hydrologic data collected and general visual
observations. Hydrologic data was collected using 40 -inch groundwater monitoring wells (or
piezometers) that collect daily groundwater elevation levels. These monitoring wells were placed
adjacent to the eight of the existing vegetation plots. Four reference monitoring wells were strategically
placed within the Project Site to act as control for existing and functional jurisdictional wetlands. These
monitoring wells are numbered (MW# 7, 14, 15 and 16). The remaining eight monitoring wells will
document hydrology throughout the areas receiving mitigation credit. Figure 4 depicts all of the
associated well locations. For hydrologic success, the restoration plan states that groundwater
elevations must be within 12 inches of the ground surface for a consecutive period no less than 5%
(approximately 12 days) of the growing season.
All 12 of the monitoring wells met the hydrologic requirements of saturation within 12 inches of the
ground surface for a period no less than 5% of the growing season. According to EEP (2009), the growing
season at the Project Site is estimated at 230 total days, ranging from March 27 through November 12.
Five of the wells exceeded the saturation requirements for more than 12.5% of the growing season.
Exhibit Table V summarizes the wetland criteria attainment. Additional information including charts

3.0 Methodology
This monitoring report follows methodology consistent with EEP's Content, Format and Data
Requirements for EEP Monitoring Reports (Version 1.2, dated 11/16/06), available at EEP's website
(http: / /www.nceep.net).
Vegetation assessments were conducted using the CVS -EEP protocol (Version 4.2). As part of this
protocol, vegetation is assessed using 100- meter 2 plots, or modules. The scientific method requires that
measurements be as unbiased as possible, and that they be repeatable. Plots are designed to achieve
both of these objectives; in particular, different people should be able to inventory the same plot and
produce similar data (Lee et. al., 2006).
According to Lee et. al. (2006), there many different goals in recording vegetation, and both time and
resources for collecting plot data are extremely variable. To provide appropriate flexibility in project
design, the CVS -EEP protocol supports five distinct types of vegetation plot records, which are referred
to as levels in recognition of the increasing level of detail and complexity across the sequence. The lower
levels require less detail and fewer types of information about both vegetation and environment, and
thus are generally sampled with less time and effort (Lee et. al., 2006). Level 1 (Planted Stem Inventory
Plots) and Level 2 (Total Woody Stem Inventory Plots) inventories were completed on all nine of the
vegetation plots at the Project Site. In addition, Level 3 (Community Occurrence Plots) inventories were
conducted on the two marsh vegetation plots.
Level 1 plots are applicable only for restoration areas with planted woody stems. The primary purpose is
to determine the pattern of installation of plant material with respect to species, spacing, and density,
and to monitor the survival and growth of those installed plants. Level 1 plots are one module in size
(Lee et. al., 2006).
Level 2 plots also are designed specifically for restoration areas and represent a superset of information
collected for Level 1 plots. In these plots planted woody stems are recorded exactly as for Level 1, but in
addition all woody stems resulting from natural regeneration are recorded by size class using separate
datasheets. These plots allow an accurate and rapid assessment of the overall trajectory of woody -plant
restoration and regeneration on a site. Level 2 plots are one module in size (Lee et. al., 2006).
Level 3 plots are used to document the overall abundance and vertical distribution of leaf area cover of
the more common species in a plot. Cover is estimated for all plant species exceeding a specified lower
level (typically 5% cover); species present but with cover lower than the cut -off may be ignored. The
information can also be used to assess vegetation successional status as well as the presence and
abundance of undesirable taxa such as invasive exotics. Additional environmental data are collected in
Level 3 plots. Optionally, woody stem data required for Level 2 plots (tallies of planted and /or natural
woody stems) may be collected for Level 3 plots to allow more accurate assessment of the rate and
direction of succession. Level 3 plots are one module in size (Lee et. al., 2006).
Twelve Ecotone WM (40 -inch) Water Level Monitors record daily groundwater elevations across the
Project Site. These wells are downloaded electronically in person approximately three times per year.

The subject project sate is an environmental restoration site of the
NCDENR Ecosystem Enhancement Program (EEP} and is
encompassed by a recorded conservation easement, but is bordered
by land under private mvnership. Accessing the site may require
traversing areas near or along the easement boundary and therefore
access by the general oublic is not permitted. Access by authorized
personnel of the state and federal agencies or their
designeeslcontractors involved in the development. overwght and
stewardship of the restoration site is permitted within the terms and
timeframes of their defined roles. Any intended site visitation or
activities by any person ourtside of these previously sanctioned roles
and activities requires prior coordination with EEP.
