2.0 GENERAL DESCRIPTION OF SURVEY AREA
The Project is located within the Southern Coastal Plain Major Land Resource
Area (MLRA), which is part of the larger South Atlantic and Gulf Slope Cash
Crops, Forest, and Livestock Land Resource Region (LRR). In this MLRA, the
most common land use is forested tracts of land that are privately held for timber
production, followed by agriculture (USDA, 2006). Major crops harvested in this
area include: Soybeans, cotton, corn, and wheat (USDA, 2006). This MLRA
supports oak -pine forests which typically consist of loblolly pine, longleaf pine,
slash pine, shortleaf pine, sweetgum, yellow oplar, red oak, and white oak
(USDA, 2006). Common understory veget onsists of dogwood, gallberry,
farkleberry, common sweet leaf, Americ , and greenbrier (USDA, 2006).
2.1 SURVEY CORRIDOR IRV NL
The survey corridor utilized 46orthe Project is 200 -feet wide and primarily
centered on a proposed transmission centerline. The new transmission line will
consist of direct embed steel H -frame tangent structures without a concrete
footing, and three pole steel angle structures with a concrete footing with an
average approximately 50 - 70 feet in height for tangent structures. A 100 -feet
right-of-way (ROW) will be utilized to accommodate the 115 kV transmission
line. App; �*l14 acres were��d t;$
o 1, all of which consisted of a
greenfiel
2.2 DRAINAMFLOODDLAINS. ANU TOPOGRAPHY
roposed route is located within two watersheds, the Fishing and Lower
oanoke. Approximately 14.5 miles of the corridor is within the Fishing
atershed drologic Unit Code UC) 03020102 and approximately 2.5 miles
falls within the owe anoke Watershed HUC 03010107. The Fishing
wat*hhedis part of the la rTar-Pamlico River Basin. The Tar -Pamlico River
Basis approximately 6,148 square miles in North Carolina and is classified
as NSensitive Water (NSW). The Lower Roanoke Watershed is part of the
larger Roanoke River Basin. The Roanoke River Basin is North Carolina's 61h
largest with 3,500 square miles encompassed in North Carolina (NC DEQ, 2017).
The proposed route within the 100 ROW intersected 15 mapped Federal
Emergency Management Agency (FEMA) 100 -year floodplain which is
illustrated in the Desktop Review Mapset included as Appendix A. Importantly,
additional floodplains may be present in the survey corridor that were not
included in the FEMA maps as these maps do not define a floodplain for all
waterbodies where a floodplain may exist.
ERM 6 Dominion Energy - May 2017
From east to west, the survey corridor intersected the Hobgood, Scotland Neck,
Dawson Crossroads, and the Enfield United States Geological Survey (USGS) 7.5
minute topographic quadrangle maps. As represented on the USGS 7.5 minute
topographic quadrangle maps, elevations within the survey corridor ranged
from approximately 700 to 800 feet above mean sea level (AMSL). Elevations
were generally lower in the south portion of the corridor which is nearer to the
St. Joseph River, and higher in the northern portion. Overall, the area exhibited
relatively minor changes in topography, and can be described as level to gently
rolling.
ERM 7 Dominion Energy - May 2017
3.0 METHODOLOGY
Several sources of information were used to complete a desktop review of the
Project area for potential wetlands, and waterbodies prior to conducting field
surveys. Biologists utilized high resolution aerial photography, U.S. Fish and
Wildlife Service National Wetlands Inventory (NWI) data, the U.S. Department
of Agriculture Soil Survey Geographical (SSURGO) Database, the U.S. Geologic
Survey National Hydrography Dataset (NHD), FEMA Floodplain maps
(Appendix A).
Field surveys were completed between February 06 and May 12, 2017. Wetland
boundaries, waterbody banks, data collection points, open waterbody boundaries,
and other information were surveyed using a Trimble® 7000 series GeoXH model
Global Positioning System (GPS) t, capable collecting data at sub -meter
accuracy.
3.1 WETLANDS
The onsite delineation of wetlands d their boundaries s conducted using
methodology described in the U.S. ArmyYorps of Engineers 1987 Wetlands Delineation
Manual (U.S. Army Corps of Engineers, 1987), and the Regional Supplement to the
Corps of Engineers Wetland Delineation Manual: Atlantic and Gulf Coastal Plain Region
(U.S. Army Corps of Engineers, 2012). The National Wetland Plant List: 2016 (NWPL)
(Lichvar et al., 2016) was used for the determination of plant indicator status, and
the Classification of Wetlands and Deepwater Habitats of the United States (Cowardin,
1979) was a classif wetlan
ccor the 1987 USACE et and Manual, three criteria or parameters are
considered g wetland delineation. In order for an area to be considered a
tland it mus et all V.
These criteria include:
1. predomina of hydrophytic vegetation,
2. indiq1AopJ0Fwetland hydrology, and
3. presence of hydric soils under normal circumstances (i.e., where naturally
problematic conditions or disturbances are absent)
USACE wetland data forms were completed at sample points within each wetland
community type (i.e., Cowardin classification) making up the wetland or wetland
complex. One corresponding upland community sample point was also taken for
each wetland or wetland complex. If more than one type of wetland was observed
within a larger wetland complex, the boundaries of the different types were
ERM 8 Dominion Energy - May 2017
collected, and a separate wetland data form was completed for each wetland type
within the wetland complex.
Additionally, for each delineated wetland, a North Carolina Wetland Assessment
Method (NC WAM) form (Version 4.1) was completed. NC WAM methodology
implementation was addressed in a public notice by The U.S. Army Corps of
Engineers (USACE), Wilmington District (District) issued on April 21, 2015. USACE
wetland data form along with NC WAM forms are located in Appendix B.
3.2 WATERBODIES
ME
Waterbodies documented during field survey were categorized as:
1) linear or flowing waterbodies pffassigned a unique ID starting with an
"s" for streams and rivers ora d" for ditchNakes
2) non -flowing open waterbodies such as pand assigned a
unique ID starting with an "o" (Table 3.0-1)
a
Linear or flowing waterbodies were identified as landscape features with a
channel that includes a defined bed and a bank in a concave landscape position
where water flo has resulted in a feature that possesses an ordinary high water
mark (OHWM). ed on evidence of flow regime at the time of survey, linear
waterbodies were attributed a flow regime according to the definitions provided
by the USACE for'f the Nationwide Permit Program in Code of Federal
Regulations (&0-) 33 Part 330 (Federal Register, 1993). Similarly non -flowing,
open waterbody features were assigned a Cowardin hydrology regime based on
servation recorded at the time of survey.
p .
qmk N&
USACE and North Carolina Department of Water Quality (DWQ) stream data forms
were completed at sample points along each stream. Stream data forms are located
in Appendix D.
3.2.1 REGIME CLASS KATION
Water regime classification is defined by its flow duration. The following regime
classifications are described below pursuant to the CFR 33 Part 330 ruling:
• Perennial Stream: A perennial stream has flowing water year round
during a typical year. The water table is located above the stream bed for
most of the year, and groundwater is the primary source of water for
stream flow. Runoff from rainfall is a supplemental source of water for
stream flow.
ERM 9 Dominion Energy - May 2017
• Intermittent Stream: An intermittent stream has flowing water during
most times of the year, when groundwater provides water for stream
flow. During dry periods, intermittent streams may not have flowing
water, and runoff from rainfall is a supplemental source of water for
stream flow.
• Ephemeral Stream: An ephemeral stream has flowing water only during
and for a short duration after precipitation events. Ephemeral stream beds
are located above the water table year und; therefore, groundwater is
not a source of water for the strea off from rainfall is the primary
source of water for stream flow.
Non -flowing or open waterbodies were documented based on the evidence of
inundation/ saturation at the time of surveys, utilizing one of four categories
based on the Classification of Wetlands and Deepwater Habitats of the United
States (Cowardin,1979) including the following:
• Permanently fl oded: Water covers the land surface throughout the year
in all years. %
• Semi -permanently ooded. Surface water persists throughout the growing
season in most years. When surface water is absent, the water table is
usually at or ver near the land surface.
VF
• Seaso y flooded: Surface water is present for extended periods
especially early in the growing season, but is absent by the end of the
season in most years. When surface water is absent, the water table is
often near the land surface.
Temporarily floodeurface water is resent for brief eriods durinthe
growing season, but the water table usually lies well below the soil surface
for ost of the season.
3.3 FEATURE AM G PROTOCOL
Specific naming conventions were followed during field surveys in order to
catalog each feature type collected. Table 3.3-1 describes the unique naming
conventions for these features.

5.0 SUMMARY OF FINDINGS
As a result of ERM's desktop and field investigation, 56 wetlands and 79
waterbodies were delineated, in whole or in part, within proposed ROW. In
addition to this, the corridor intersected 15 FEMA 100 -year floodplain. As such,
impacts to these features as part of the proposed Project will require the
submission of applicable permits and the approval of USACE prior to
construction.
