1.0INTRODUCTION
This report presents the findings of the wetland and stream delineation study conducted by ECS
Southeast, LLP (ECS) for Blue Granite Water Company at the Bradfield Farms - Silverton Water
Interconnect located 4236 Fellows Lane, Harrisburg, Cabarrus County, North Carolina
(35.2595082,-80.6454538). According to the Cabarrus County GIS website, the site comprises Parcel
No(s). 55058384670000 and 55059312030000. The study area includes approximately 1,620 linear
feet, as shown on the Site Location Map (Appendix I, Figure 1). The site currently consists of consists
of undeveloped, moderately wooded land. The purpose of this study was to identify and delineate
jurisdictional Waters of the U.S. (WOUS) within the project study area (PSA).
Wetlands are defined by the United States Army Corps of Engineers (USACE) and the United States
Environmental Protection Agency (EPA) as "those areas that are inundated or saturated by surface
or groundwater at a frequency and duration sufficient to support, and under normal circumstances,
do support a prevalence of vegetation typically adapted for life in saturated soil conditions." In order
for an area to be classified as wetland, hydrophytic vegetation, hydric soils, and wetland hydrology
indicators must be present described in the 1987 "Corps of Engineers Wetlands Delineation Manual"
and the Appropriate Regional Supplement.
2.0 METHODOLOGY
This WOUS delineation is based on ECS' professional judgment and application of the technical
criteria presented in the 1987 USACE Wetlands Delineation Manual, and on the Regional Supplement
to the Corps of Engineers Wetland Delineation Manual: Eastern Mountains and Piedmont Region,
Version 2.0 dated April 2012.
ECS completed the following tasks to identify and delineate potentially jurisdictional WOUS
boundaries onsite:
2.1 Literature Review
ECS wetland scientists reviewed the US Geological Survey (USGS) Topographic Map, US Department of
Agriculture Natural Resource Conservation Service (USDA-NRCS) Soil Survey of Cabarrus County, the
USDA NRCS 2015 National Hydric Soils List for Cabarrus County, the Federal Emergency Management
Agency (FEMA) Floodplain Mapping Service, US Fish & Wildlife Service (USFWS) National Wetlands
Inventory (NWI) Wetlands Mapper, and available aerial photographs to identify potentially
jurisdictional Waters of the US (i.e., streams, wetlands, natural ponds, lakes), and available watershed
information.
2.2 Methodology for Field Investigation
Wetland boundaries were delineated using the routine onsite determination method described in the
USACE Manual and Regional Supplement, in conjunction with the Piedmont 2016 Regional Wetland
Plant List, and the USDA Soil Survey.
ECS Project # 49:14290

ECS Southeast, LLP
ECS performed onsite wetland delineations as described above. First, site hydrology was observed
and the plant community within the data plot was characterized. The dominant plant species within
each community were then identified, and it was determined whether or not hydrophytic (wetland)
plants dominated the plant community. The USFWS has defined five wetland plant indicator
categories including:
• Obligate wetland (OBL) - has >99% probability of occurring in wetlands
• Facultative wetland (FACW) - has 66% to 99% chance of occurring in wetlands
• Facultative (FAC) - has 33% to 66% chance of occurring in wetlands
• Facultative upland (FACU) - has 1 to 33% chance of occurring in wetlands
• Upland (UPL) - has <1 % chance of occurring in wetlands
• No Indicator (NI) - no wetland indicator for the specified species, considered UPL
Plants identified as OBL, FACW, or FAC are considered wetland plants (or hydrophytes) by USACE.
In areas determined to have hydrophytic vegetation and potential wetland hydrology, an
approximately 16-24 inch hand auger soil boring or shovel test pit was completed to determine if
hydric soils were present. The soil boring was also inspected to determine if indicators of wetland
hydrology (inundation, soil saturation, etc.) were present.
Once an area is determined to be a wetland, further testing was performed to locate the wetland/
upland (non -wetland) boundary. A second soil data point was completed in the upland area to
document non -wetland conditions. Wetland boundaries were marked with consecutively numbered
surveyor's ribbon flags.
Data forms specified in the Regional Supplement were completed for each wetland and non -wetland
soil data point location. The data forms recorded the vegetation, soils, and hydrology observations
used in making the wetland determinations.
2.3 Methodology for Delineating Streams
During the field investigation for wetlands, ECS identified streams onsite that would be considered
jurisdictional by state and federal regulatory agencies. ECS used field indicators such as flow,
substrate composition, presence/absence of defined bed and banks, origin of hydrologic source,
presence/absence of vegetation in the stream channel, and composition and relative abundance of
resident benthic mac roinvertebrates to classify onsite streams into three stream types: ephemeral,
intermittent, and perennial.
3.0 FINDINGS
3.1 Literature Review Summary
The following is a summary of the available desktop information that was reviewed as part of this
WOTUS Delineation:
• According to the USGS Topographic Map, Charlotte, North Carolina Quadrangle dated
1988 (Figure 2), the PSA is situated at an approximate elevation of 550-650 feet above mean
sea level (MSL).
ECS Project # 49:14290
Page 2

ECS Southeast, LLP
According to the NRCS Cabarrus County Soil Survey, (Figure 3), soils on the PSA have been
mapped as Unit(s) IdB: Iredell loam, 2 to 6 percent slopes, PoD: Poindexter loam, 8 to 15
percent slopes, ChA: Chewacla sandy loam, 0 to 2 percent slopes, frequently flooded. The
aforementioned soils were not listed as hydric soils on the national hydric soils list for
Cabarrus County, North Carolina.
• The FEMA Flood Insurance Rate Maps (FIRMS), Panel 3710550500M, dated November 16,
2018 (Figure 4) indicates the PSA is located in Zone AE.
• The US Fish and Wildlife NWI map (Figure 5) does not identify wetlands in the PSA but
identifies one riverine features and McKee Creek through the PSA.
• The site is located within the Reedy Creek watershed and is identified as Hydrologic Unit
Code (HUC) 030401050302.
3.2 Field Investigation Findings
ECS personnel conducted the field investigation on June 28, 2021. The last precipitation event prior
to the site reconnaissance was on June 23, 2021 and approximately 0.06 inch was recorded. During
the reconnaissance, ECS observed the PSA for evidence of WOUS, including ponds, streams, and
wetlands.
Jurisdictional streams were marked with blue flagging tape along each bank and located using a
Trimble Geo7X hand-held GPS unit capable of sub -foot accuracy. ECS identified one jurisdictional
stream, summarized in Table 1 below.

Stream S1 (McKee Perennial N/A approx. 100
Creek)
4.0 REGULATORY DISCUSSION
The WOUS are regulated by Sections 401 and 404 of the Clean Water Act. State and Federal law
dictates that any disturbance to WOUS must be permitted through the appropriate agencies.
Upon your request, we will contact the USACE to schedule a field meeting to conduct a wetlands
and Waters boundary confirmation and preliminary jurisdictional determination. The timeline of this
process is dependent on the availability of the regulator. If any potential impacts are proposed,
we can assist you with permitting options and support to complete the process. In the interim,
we recommend further review of state and federal agency records pertaining to Section 7 (Federal
Endangered Species Act) and Section 106 (National Historic Preservation Act). These reviews will
generally be required to verify compliance for either the Nationwide Permit (NWP) or General Permit
conditions.
ECS Project # 49:14290

If jurisdictional wetlands and streams are present at the site, planned land disturbance in these areas
would likely require a permit from the USACE and/or the North Carolina Division of Water.
.0 WATERSHED CLASSIFICATION/BUFFER REQUIREMENTS
5.1 State Riparian Buffer Requirements
The site is located in the Yadkin Pee Dee River Basin. Surface waters within the Yadkin Pee Dee River
basin are not subject to State mandated riparian buffers.
5.2 Local Buffer Requirements
ECS reviewed the Cabarrus County Code of Ordinances to determine if the county has vegetative
buffer requirements for surface waters. According to the Ordinance, a minimum one hundred -foot
vegetative buffer is required for all new development activities that exceed the low density option;
otherwise, a minimum fifty -foot vegetative buffer for development activities is required along all
perennial waters indicated on the most recent versions of U.S.G.S. 1:24,000 (7.5 minute) scale
topographic maps or as determined by local government studies. Desirable artificial streambank or
shoreline stabilization is permitted.
ECS recommends consultation with a civil engineer to determine if mandatory vegetative buffers and/
or regulated development (impervious surfaces) setbacks are required for the site in addition to those
mentioned above.
5.3 Stormwater Requirements
Surface waters located within the PSA appear to flow to the Yadkin Pee Dee River, which is classified
as a Class C water. Class C waters are protected for uses such as secondary recreation, fishing,
wildlife, fish consumption, aquatic life including propagation, survival and maintenance of biological
integrity, and agriculture. Secondary recreation includes wading, boating, and other uses involving
human body contact with water where such activities take place in an infrequent, unorganized,
or incidental manner. ECS reviewed the NCDWR online stormwater permitting map to determine
jurisdiction of NCDWR stormwater regulations. According to the online permitting map, it appears
the site is located in an area designated as Local Permitting Authority. ECS recommends consultation
with a civil engineer to determine if mandatory vegetative buffers and/or regulated development
(impervious surfaces) setbacks are required for the site in addition to those mentioned above.
6.0 CONCLUSIONS
One jurisdictional streams totaling approximately 100 linear feet was identified and delineated within
the study area. The locations and boundaries of jurisdictional Waters are illustrated on the attached
Waters of the U.S. Delineation Map (Figure 6).
The flagged WOUS boundaries are subject to change during the jurisdictional determination meeting
with the USACE. ECS cannot guarantee that field conditions and/or WOUS boundaries will not change
over time.
