CWS Project No. 2018-0286
Dear Ms. Sutton,
Willis Engineering has contracted Carolina Wetland Services, Inc. (CWS) to provide a
Jurisdictional Delineation for the Dutchman's Creek Parallel Sewer site. The Dutchman's Creek
Parallel Sewer site is a 8,700 linear foot sewer line corridor totalling approximately 16.5 acres in
extent. The corridor begins at Lanier Avenue, and runs north along Dutchman's Creek for
approximately 1.5 miles to Sandy Ford Road, in Mount Holly, North Carolina (Figure 1).
Street Address of Project: Begins at Lanier Avenue, and runs north along Dutchman's Creek
for approximately 1.5 miles to Sandy Ford Road, in Mount Holly, North Carolina
Waterway: Dutchman's Creek
Basin: Catawba River (HUC1 03050101)
City: Mount Holly
County: Gaston
Tax Parcel No(s): Linear project encompassing multiple Gaston County Tax Parcels
Decimal Degree Coordinate Location of Project Site: 35.32754°, -81.019513°
USGS Quadrangle Name: Mount Holly, NC (2017)
Current Land Use
The project area consists of undeveloped forested areas, and a maintained sewer line
right-of-way. On-site elevations range from 580-640 feet above mean sea level (Figure 2).
Land cover within the project area consists of deciduous forest, herbaceous area, and woody
wetlands (Figure 3)2.
According to the United States Department of Agriculture - Natural Resources Conservation
Service (USDA-NRCS)Web Soil Survey of Gaston County3 (Figure 4) and the NRCS Historic
Soil Survey for Gaston County' (Figure 5), on-site soils consist of five different soil types (Table

National Wetlands Inventory
Wetlands are an important source of biodiversity and provide a multitude of ecological services.
The National Wetlands Inventory(NWI), created by the U.S. Fish and Wildlife Service, is a
program which provides wetland data and analysis to the public. A review of the NWI GIS layer
depicts a freshwater forested/shrub wetland occurring in the central portion of the project limits.
(Figure 6).
Jurisdictional Delineation
The U.S. Army Corps of Engineers (USACE) and the Environmental Protection Agency (EPA)
define wetlands as: "Those areas that are inundated or saturated by surface or groundwater at a
frequency and duration sufficient to support, and that under normal circumstances do support, a
prevalence of vegetation typically adapted for life in saturated soil conditions."' The USACE
uses three parameters to identify jurisdictional wetlands: 1) hydrophytic vegetation, 2)wetland
hydrology, and 3) hydric soils. Except in certain atypical situations, all three parameters must be
present in order for an area to be determined to be a jurisdictional wetland.
Jurisdictional areas were delineated (flagged in the field), classified, and mapped with a sub-foot
Trimble Geo7X GPS unit using the (USACE) Routine On-Site Determination Method. This
method is defined in.the 1987 Corps of Engineers Delineation Manuals the 2007 USACE
Jurisdictional Form Instructional Guidebook,'with further technical guidance from the 2012
Eastern Mountains & Piedmont Regional Supplement.' Data representative of on-site
non jurisdictional upland areas was collected and reported using Wetland Determination Data
Forms (Attachment A).
Jurisdictional stream channels were classified according to the North Carolina Department of
Environmental Quality (NCDEQ) guidance based on biological, hydrological, and physical
characteristics. These classifications include sampling with a D-shaped dip net, collecting

photographic documentation, and defining approximate breakpoints (location at which stream
channel changes classification)within each on-site stream channel. NCDEQ Stream
Classification Forms representative of on-site stream channels were used to document stream
conditions (Attachment B).
Representative photographs were taken of on-site jurisdictional features and existing site
conditions (Attachment C). Locations of mapped wetlands and other waters, Stream
Classification Points, Wetland Determination Data Forms, and representative photographs are
depicted on Figure 7.
Results
On May 2, 2019 Carolina Wetland Services, Inc. (CWS) scientists Megan Shelton, WPIT9, Staff
Scientist II, and Hannah Meeler, Staff Scientist I, delineated on-site jurisdictional waters of the
U.S., including wetlands. Based on the results of this field investigation, there are two
jurisdictional waters of the U.S. located within the project boundary totalling approximately 0.02
acres, including 56 linear feet of jurisdictional stream channel (Figure 7).

Jurisdictional Wetlands
One jurisdictional wetland area (Wetland AA)was delineated within the project area (Figure 7).
Wetland AA is a palustrine herbaceous wetland located in the central portion of the site, and is
approximately 0.01 acres in extent (Photograph 1). Wetland AA is sparsely vegetated concave
surface and contains small amounts of spotted lady's thumb (Persicaria maculosa) and
jewelweed (Impatiens capensis). Soils displayed prominent redox concentrations with oxidized
rhizospheres on living roots (DP1).
Jurisdictional Streams
One perennial stream channel (Stream A)was delineated within the project area (Figure 7).
Stream A originates off-site in the southern portion of the project limits, and has perennial flow to
the west/northwest for approximately 56 linear feet before flowing off-site and into a confluence

with Dutchman's Creek. Stream A exhibits strong continuity of bed and bank, strong substrate
sorting, and strong baseflow (SCP1; Photograph 2).
Non-Jurisdictional Upland Areas
No additional waters of the US were delineated within the project area (Figure 7). Wetland
Determination Data Forms representative of non jurisdictional upland areas are attached as
DP2 and DP3 (Photographs 3 and 4). An NCDEQ Stream Classification Form representative of
a non jurisdictional stormwater conveyance is attached as SCP2 (Photograph 5).
Recommendations
CWS recommends submitting the results of this delineation to the USACE for verification.
Wetlands and other waters are present on the site, which are regulated by the USACE and/or
NCDWR. The jurisdictional delineation provided by CWS represents our best professional
judgment regarding the boundaries of on-site wetlands, streams, and other water features that
can be used for preliminary project planning. However, until a Jurisdictional Determination (JD)
is issued by a regulatory agency (USAGE), the delineation can only be considered preliminary
and is not an official governmental approval. CWS recommends that before any construction or
other earth disturbance activities occur on site, a formal JD should be obtained.
Thank you for the opportunity to provide these services on this important project. Please do not
hesitate to contact Aliisa Harjuniemi at 980-259-1222 or [e-mail] should you have
any questions or comments regarding this report.
