Mr. Paukovich,
Froehling & Robertson, Inc., (F&R) presents herein the results of the stream and wetland delineation for the
Wilson’s Mills Hydraulic Improvements project. The goal of this project is to meet growing water demands by
replacing various sections of Wilson’s Mills’ water transmission system. The scope of this project encompasses
a total of approximately 27,500 linear feet (LF) of proposed water main between the town of Wilson’s Mills
and the US-70 Business / US-70 Bypass Interchange along Gordon Road and a portion of US-70 Business. The
majority of the proposed water main alignment is planned within the road right-of-way (ROW). The project
site consists of existing public ROW, residential and commercial properties, wooded areas as well as
maintained lawns. The review area contains approximately 86 acres o f right-of-way (ROW). The ROW consists
of road fill adjacent to wetlands, agricultural land, and improvements related to residential housing. Existing
12” water mains are being replaced by larger diameter pipe.
EXECUTIVE SUMMARY
This executive summary of our findings is not intended to replace more detailed information contained
elsewhere in this report. Based on F&R’s field observations and information review, four likely jurisdictional
wetlands (W4, W5, W6, and W8), and three likely jurisdictional streams (S9, S10, and S11) were identified and
delineated within the review area during our assessment. The identified features are shown on the attached
Wetland Delineation Map (Figure 7). Please note that additional wetland and stream features were observed

F&R Project No. 66X-0345 2 May 8, 2020
in the vicinity of the review area but are not identified or addressed in this report since they will not be
affected by the proposed project.
SCOPE OF SERVICES
This report describes the activities and findings associated with the completion of a stream and wetland
assessment for the above-referenced review area. F&R reviewed applicable information sources to identify
areas on the project site that could be considered “Waters of the US” (i.e., wetland, stream, and open water
features) and subject to jurisdiction by Environmental Protection Agency (EPA), United States Army Corps of
Engineers (USACE) and/or North Carolina Division of Water Resources (NCDWR). On-site identification of
wetlands was performed in general accordance with the 1987 Corps of Engineers Wetlands Delineation
Manual and subsequent USACE clarification memorandums. On-site identification of streams was performed
in general accordance with the NCDWR Identification Methods of the Origins of Intermittent and Perennial
Streams.
SITE CONDITIONS
Information Review
F&R reviewed all or some of the following resources prior to visiting the project site: United States Geological
Survey (USGS) 1:24,000-scale topographic map, Natural Resource Conservation Service (NRCS) Soil Survey,
National Wetland Inventory (NWI), and aerial photographs. Based on F&R’s information review, three
potentially jurisdictional stream features (S9, S10 and S11) were mapped on the NRCS Soil Survey; however,
only one stream (S9) was mapped on the USGS Topographical and National Wetland Inventory Maps.
Additionally, wetland areas were not depicted on the maps reviewed. Each of the three mapped stream
features as well as several wetland areas were observed within the review area during our on-site assessment.
Those findings are detailed below and locations of the identified features are shown on the attached figures.
The NRCS Soil Survey maps indicate seven soil series within the project review area: Appling Marlboro
Complex (AmB), Cowarts Loamy Sand (CoA), Grantham Silt Loam (Gr), Marlboro Sandy Loam (MaA), Norfolk
Sandy Loam (NoA), Toisnot Loam (Tn), and Varina Loamy Sand (VrA). Of the soils mapped within the project
area, Grantham Silt Loam and Toisnot Loam are considered to be hydric. Hydric soils are defined as “soil that
formed under conditions of saturation, flooding, or ponding long enough during the growing season to
develop anaerobic conditions in the upper part.” The presence of hydric soils is one of three wetland
delineation criteria.
On-Site Observations
The review area consisted of a variable width corridor within the right-of-way of Gordon Road and US 70
Business, as well as along Powhatan Road. On Gordon and Powhatan Roads, the review area ranges from 30
feet to 45 feet beyond edge of pavement (EOP) depending on the location. On US 70 Business, the review area
is generally 50’ from EOP. Four likely jurisdictional wetlands (W4, W5, W6, and W8) and three likely
jurisdictional streams (S9, S10, and S11) were identified and delineated within the review area during our
assessment. The wetland features exhibited each of the characteristics of wetlands (hydrology, hydric soils,
and hydrophytic vegetation). As such, these features are likely to be considered jurisdictional by the USACE
and may be claimed by NCDWR. Based on F&R’s on-site observations, the above-listed features are each likely
to be considered jurisdictional “Waters of the US” (WOTUS) by the USACE and/or NCDWR; however, on-site
determinations by the USACE and NCDWR will be required in order to confirm or deny jurisdiction by these
McKim & Creed 385 West Transmission Improvements – Wetland Services
F&R Project No. 66X-0345 3 May 8, 2020
two regulatory agencies. The approximate locations of the mapped surface features are shown on the
Wetland Identification Map in the Attachments and are described as follows:
Wetland 4 – located in the southeastern portion of the review area west of Brandywood Drive, this
riparian Palustrine Forested feature is situated along the north side of Gordon Road and functions as
floodplain for stream feature S9 (Little Poplar Creek). W4 is adjacent to S9 and drains into a culvert
associated with S9 that passes beneath Gordon Road and flows to the south.
*Note: features W1 through W3 were determined to be outside of the review area and thus are
not identified or addressed in this report.
Wetland 5 – a Palustrine Emergent wetland that runs along the north side of Gordon Road near the
intersection with Slateford Drive and drains into a roadside ditch, then into a culvert under Gordon
Road, followed by a culvert under Slateford Drive, and on to the west toward S9. There appears to
have been some historic clearing of this wetland area with associated soil disturbance.
Wetland 6 – a riparian Palustrine Emergent feature that is located along the north side of Gordon
Road just west of W5 and functions as a portion of the floodplain for stream feature S10. Similar to
feature W5, there appears to have been some historic clearing of this wetland area with associated
soil disturbance.
*Note: feature W7 was determined to be outside of the review area and thus is not identified or
addressed in this report.
Wetland 8 – a Palustrine Forested feature that is located along the north side of Gordon Road just
east of the intersection with Wise Road. This wetland drains into stream feature S11 (Reedy Branch)
and functions as a portion of the floodplain associated with that stream feature.
Stream 9 (Little Poplar Creek) – a perennial stream channel located in the southeastern portion of
the review area and classified as Riverine Unconsolidated. The channel is identified as “Little Poplar
Creek” and shown as a blue line feature on the current USGS Topographical Map and as a stream
feature on the NRCS Soil Survey Map. The feature is anticipated to be subject to Neuse River
Riparian Buffer Rules as well as Johnston County’s riparian buffer requirements as referenced in the
Johnston County Buffer Ordinance Sec. 14-393.
*Features S1 though S8 were determined to be outside of the review area and thus not
identified or addressed in this report.
Stream 10 – an unnamed intermittent stream channel located in the northern portion of the review
area and classified as Riverine Unconsolidated. This feature is not shown as a blue line feature on
the current USGS Topographical Map; however, the feature is mapped on the Johnston County
NRCS Soil Survey Map. As such, the feature is anticipated to be subject to Neuse River Riparian
Buffer Rules as well as Johnston County’s riparian buffer requirements as referenced in the Johnston
County Buffer Ordinance Sec. 14-393.
Stream 11 (Reedy Branch) – a perennial stream channel located in the northern portion of the
review area just east of the intersection with Wise Road, this perennial channel can be classified as
Riverine Unconsolidated. This feature is not shown as a blue line feature on the current USGS
Topographical Map; however, the feature is mapped on the Johnston County NRCS Soil Survey Map
as “Reedy Branch.” As such, the feature is anticipated to be subject to Neuse River Riparian Buffer
Rules as well as Johnston County’s riparian buffer requirements as referenced in the Johnston
County Buffer Ordinance Sec. 14-393.

Please see the attached Figures for a graphic depiction of the features identified and described above.
Additionally, photographs and data forms are included within the attachments as documentation of the
information described above.
CONCLUSION
Based on F&R’s information review and on-site observations, four likely jurisdictional wetlands (W4, W5, W6,
W8) and three likely jurisdictional streams (S9, S10, S11) were identified and delineated within the review area
during our assessment. It is F&R’s opinion that portions of wetlands and streams that occur within the review
area are likely to be considered jurisdictional WOTUS by the USACE and/or NCDEQ as outlined above. Based
on this assumption, the features would be subject to USACE or NCDEQ regulations in accordance with the
Clean Water Act (CWA); however, on-site determinations by the USACE and/or NCDEQ would be required in
order to confirm or deny jurisdiction by these two regulatory agencies. Additionally, since the assessment area
is located within the Neuse River Basin and within Johnston County, the site is also under the jurisdiction of
the Johnston County Buffer Ordinance and subject to the Riparian Buffer Protection Standards and Wetland
Protection Standards contained therein.
Please note that the attached Wetlands Identification Map prepared by F&R is meant for use as a reference
document only. This map is not designed to satisfy any requirement for a survey plat by a licensed surveyor
nor is it intended to be used for construction purposes or relied upon for the jurisdictional limits of the
mapped surface features.
GENERAL GUIDANCE
F&R recommends that plans for development of the subject property consider the USACE and NCDWR
procedures for assessing impacts to jurisdictional wetlands and/or streams (i.e., avoid, minimize, and mitigate)
to optimize permitting strategies.
If proposed development on the project site does not result in impacts to wetland areas, the areas
immediately adjacent to wetland boundaries, or the identified Waters of the US, a USACE permit will not be
necessary. Typical activities requiring USACE permitting include, but are not limited to, depositing of fill or
dredged material in wetlands; site development fill; construction of revetments, groins, breakwaters, levees,
dams, dikes, and weirs; and placement of riprap and road fill.
If impacts to these areas are anticipated, F&R recommends that site plans be developed that optimize
permitting strategies to comply with the USACE, NCDWR, and local municipality procedures for assessing
impacts to jurisdictional wetlands and/or “Waters of the US” (i.e., avoid, minimize, and mitigate).
If future impacts to jurisdictional wetlands and/or streams are anticipated, the appropriate permit
applications for regulatory review must be completed prior to any initiation of activities that may require
permitting.
F&R can provide alternative design measures and make the written request based upon extensive experience
and professional relationships with the USACE and NCDWR throughout North Carolina in the event that
impacts are unavoidable and written authorization needs to be requested.
