City: Mooresville
County: Iredell
Tax Parcel No(s): Linear project encompassing multiple Iredell County tax parcels.
Decimal Degree Coordinate Location of Project Site: 35.6000640,-80.7943710
USGS Quadrangle Name: Mooresville, NC (2019)
Current Land Use
The project area consists of undeveloped forested areas, herbaceous areas, and maintained

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 two potential jurisdictional riverine systems and one potential jurisdictional wetland
within the project limits (Figure 6).
FEMA National Flood Hazard
FEMA National Flood Hazard Layer was reviewed for the project area (FEMA Panels
3710466700J). The Wiggins Road Gravity Sewer and Force Main site is located within the 1 %
Annual Chance Flood Hazard, 0.2% Annual Chance Flood Hazard, and Area of Minimal Flood
Hazard Zone (Figure 7).
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."5 The USACE
uses three parameters to identify jurisdictional wetlands. These parameters are as follows: 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 Manual,6 the 2007 USACE
Jurisdictional Form Instructional Guidebook,' with further technical guidance from the 2012
United States Department of Agriculture — Natural Resources Conservation Service, 2011. Soil Survey of Iredell County,
North Carolina.

Jurisdictional Delineation Report CWS Project No. 2019-0326
Eastern Mountains & Piedmont Regional Supplement .8 Data representative of on -site
jurisdictional wetland areas and non -jurisdictional upland areas was collected and reported
using Wetland Determination Data Forms (DP; Attachment A).
Jurisdictional stream channels were classified (perennial, intermittent, or ephemeral) 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 (SCP; 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 8.
Results
On June 16, 2020, Carolina Wetland Services, Inc. (CWS) scientists Megan Shelton, WPIT9 and
Amie Hoy, WPIT delineated on -site jurisdictional waters of the U.S., including wetlands. Based
on the results of this field investigation, there are three jurisdictional waters of the U.S. located
within the project boundary totalling approximately 0.03 acre, including 132 linear feet of
jurisdictional stream channel (Figure 8). These waters consist of three potentially jurisdictional
stream channels (Stream A-C). Table 2 summarizes the potential jurisdictional waters of the
U.S. within the property.

Jurisdictional Streams
Three perennial streams (Stream A-C) were delineated within the project limits (Figure 8).
Stream A (Back Creek) originates off site in the northern portion of the project boundary and has
perennial flow to the northeast for approximately 31 linear feet until flowing off site. Since
Stream A is a named, perennial stream depicted on the USGS map, a NCDEQ Stream
Classification Form was not collected (Photograph 1).

Stream B originates off site in the southern portion of the project boundary and has perennial
flow to the southeast for approximately 50 linear feet until flowing into a confluence with Stream
C. Stream B exhibits strong baseflow and moderate in -channel structure (Photograph 2;
SCP1).
Stream C originates off site in the central portion of the project boundary and has perennial flow
to the north for approximately 51 linear feet until flowing off site. Stream C exhibits strong
baseflow and strong in -channel structure (Photograph 3; SCP2).
Non -Jurisdictional Areas
No additional jurisdictional waters of the US were delineated within the project area (Figure 8).
A Wetland Determination Data Form representative of non -jurisdictional upland areas is
attached as DP1 (Photograph 4).
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
NCDEQ. 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 (USACE), 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.

Herb - All herbaceous (non -woody) plants, regardless
of size, and woody plants less than 3.28 ft tall.
Woody Vine - All woody vines greater than 3.28 ft in
