Dear Mr. Shaeffer and Ms. Higgins:
On behalf of Duke Energy (Duke), S&ME, Inc. (S&ME) is submitting this courtesy notification to inform you of work
they plan to conduct in accordance with Nationwide Permit (NWP) 13 and General Water Quality Certification
(WQC) 3134 in order to stabilize two segments of eroding streambank on their property.
The general project area is located north of Springbrook Road and west of Chastain Avenue in an urbanized
portion of Charlotte, Mecklenburg County, North Carolina (35.175009°N, -80.884042°W). This Pre -construction
Notification (PCN) is being submitted to the U.S. Army Corps of Engineers (USACE) and the North Carolina
Division of Water Resources (NCDWR) as a courtesy. The project as currently proposed will entail less than 150
linear feet (If) of permanent streambank impacts, and should not require pre -construction written approval from
either agency. In support of this application, the following accompanying information has been submitted
through the NCDWR On-line PCN website (https://edocs.deg.nc.gov/Forms/Pre-Construction Notification FormU:

Woodlawn Substation Streambank Stabilization
September 17, 2018
The work will require approval by Mecklenburg County Stormwater Services for impacts to the SWIM buffer
established along the stream, and approval of an erosion and sediment control plan will also be required from the
NC Division of Energy, Mineral and Land Resources (NCDMLR). Applications and supporting materials pursuant
tthose approvals will be submitted separately and authorized by the respective agencies prior to initiation of
construction.
Project Purpose and Need
The purpose of the proposed project is to provide long-term stabilization to two segments of eroding
streambank, hereafter identified as the North Area and South Area, that have the potential to undermine existing
Duke infrastructure. The work will be conducted in conjunction with a security upgrade project that will involve
replacement of the existing fencing around the substation and installation of added security measures around
telecommunication towers/buildings and above -ground storage tanks at the site.
Existing Site Conditions
The proposed site is located within an existing parcel owned by Duke and is comprised of mixed vegetated and
impervious areas. Based on a review of the USGS Quadrangle (Figure 2), an unnamed tributary of Kings Branch is
located along the western perimeter of the Site. The USDA NRCS Mecklenburg County Soil Resource data (Figure
3) depicts the Site as being underlain by the Cecil sandy clay loam and Cecil -Urban land complex. The USFWS
NWI program did not indicate the presence of wetland features within the Site.
Jurisdictional boundaries within the project area were delineated by S&ME on December 13, 2017. One
jurisdictional surface water feature (Stream 1) was observed and delineated. Stream 1 is an unnamed tributary to
Kings Branch (DWR Index No. 11-137-6, Class Q. Stream 1 is a perennial stream based on existing ordinary high
water mark and biological indicators. The stream channel is approximately 5 to 8 feet in width (on average) and
exhibited consistent flow at the time of the field reconnaissance. Jurisdictional wetlands were not observed in
association with the stream feature.
During field reconnaissance, it was observed that the left bank of Stream 1 at the South Area, at its closest
proximity to the substation site, is approximately 7 to 10 feet away from the existing fence. Also, the stream bank
is eroded and incised to approximately 6 feet, and appears to have migrated over time towards the site based on
the appearance of an existing stormwater outfall pipe. A segment of similarly eroding streambank was observed
at the North Area near the base of an existing electric transmission tower on Duke property, north of the fenced
area.
Description of Proposed Work and Impacts
Duke intends to stabilize the subject streambanks to inhibit erosion, prevent further channel migration and
maintain reasonable separation between the stream and the infrastructure. Due to the importance of the Duke
facilities, the nature of the eroded streambank and the limited space between the streambank and the
infrastructure, it was determined that bank stabilization at the North and South Areas would be best accomplished
through construction of a "Redi-Rock" retaining wall at each area. The walls are constructed using precast,
modular blocks that will be installed near the toe of the eroding streambank, and will provide protection for the

tower footings and substation pad. The proposed streambank impacts that will occur as a result of the project are
identified in Table 1 below:
Table 1: Summary of Proposed Streambank Impacts
Streambank Impacts (If)
anks Stabilization Area
Tem r
Prior to construction at each site, a sand bag cofferdam and cleanwater bypass will be established in order to
create a dry work area and prevent flowing water from coming in contact with the work area. Perimeter erosion
and sediment controls will be installed in adjacent work areas. Construction of the project will include clearing
and grubbing within the defined limit of disturbance, cut and fill necessary to prepare the area above the
streambank, and installation of the Redi-Rock wall and two small areas of riprap at the toe of the wall.
The project will employ appropriate sediment and erosion control practices as outlined in the most recent version
of the North Carolina Sediment and Erosion Control Planning and Design Manual. Following construction,
temporarily -disturbed upland areas will be restored in accordance with the project construction drawings,
including a native riparian seed mix. The proposed project will not result in an appreciable increase impervious
surface, and no stream channelization or wetland impacts are anticipated.
Federally -Protected Species
The project has also been designed to comply with the applicable conditions of Department of the Army NWP No.
13 (Bank Stabilization) from the USACE, and WQC) No. 3134 from the NCDWR, and as proposed, should not
require written approval.
To determine the project's compliance with applicable sections of the Endangered Species Act (ESA) of 1973 (16
USC 1531-1543), S&ME conducted a search of the North Carolina Natural Heritage Program (NCNHP) database to
identify element occurrences (EOs) of such species listed as potentially occurring near the project area. The
NCNHP list was compared to the U.S. Fish and Wildlife Service (USFWS) list of protected species for Mecklenburg
County. Additionally, S&ME personnel conducted a pedestrian field review of the site in conjunction to locate
potential habitat or the presence of protected terrestrial species that were identified through the records review.
The assessment did not include sampling or a habitat assessment for aquatic or state -listed species.
The NCNHP provided an August 20, 2018 report that did not identify records of rare species, important natural
communities, natural areas, conservation areas or federally -protected species documented within one mile of the
site. The NCNHP report is included in the accompanying information submitted with the online courtesy PCN.
Based on review of the NCNHP and U.S. Fish & Wildlife (FWS) databases, federally -protected species with
documented populations in Mecklenburg County are listed in Table 2.

Descriptions of the relevant species taken from FWS profiles are also listed below.
Bald Eagle
Bald eagles were removed from the endangered species list in August 2007 because their populations recovered
sufficiently. However, bald and golden eagles are still protected under the Migratory Bird Treaty Act (MBTA) and
the Bald and Golden Eagle Act (Eagle Act). The bald eagle is a large raptor with a wingspan of approximately
seven feet. Adult individuals of this species have a mainly dark brown plumage with a solid white head and tail.
Bald eagles develop adult plumage in the fifth or sixth year. Juveniles of the species exhibit a chocolate brown to
blackish plumage with occasional occurrences of white mottling on the tail, belly, and under -wings. Bald eagle's
primary diet consists of fish. However, it will feed on birds, mammals, and turtles when fish are not available.
The bald eagle is associated with coasts, rivers, and lakes, usually nesting near large bodies of water where it
feeds. Nesting habitat in the Carolinas usually occurs in large pine trees along the edge of large bodies of water.
The bald eagle is listed as a current record for Mecklenburg County. The project area does not contain suitable
habitat for bald eagle, and there are no large bodies of water in the vicinity of the site.
Northern Long-eared Bat
The northern long-eared bat (NLEB) is a medium-sized bat about 3 to 3.7 inches in length but with a wingspan of
9 to 10 inches. This bat is distinguished by its long ears, particularly as compared to other bats in its genus,
Myotis, which are actually bats noted for their small ears. NLEB spend winter hibernating in caves and mines,
called hibernacula. They use areas in various sized caves or mines with constant temperatures, high humidity, and
no air currents. During the summer, NLEB roost singly or in colonies underneath bark, in cavities or in crevices of
both live trees and snags (dead trees). Males and non -reproductive females may also roost in cooler places, like
caves and mines. This bat has also been found rarely roosting in structures, like barns and sheds. White -nose
syndrome (WNS), a deadly fungal disease that impacts cave -dwelling bats, represents the principal threat to this
species.
Although the project area may contain potentially suitable summer foraging habitat, it is not located within 0.25
mile of known NLEB hibernacula, and will not involve cutting or destroying known, occupied maternity roost trees
or any other trees within a 150 -foot radius around known, occupied maternity trees.

Carolina Heelsplitter
The Carolina heelsplitter is most often found in small to large streams with shaded banks and a variety of
substrates. The shell covering of this mollusk is typically yellowish or greenish brown, and may have greenish
brown or black rays. The general shape of the shell is trapezoidal. There are two lateral teeth in the left valve and
one in the right valve.
Carolina heelsplitter is known from the Duck and Goose Creek subbasins of the Yadkin -Pee Dee river basin. The
study area drains into an unnamed tributary of Kings Branch, which drains into Sugar Creek. The project area
does not drain into tributaries or contain headwaters that flow into Duck or Goose Creeks and accordingly, does
not contain habitat for Carolina heelsplitter.
Rusty Patched Bumblebee
Historically, the rusty patched bumble bee was broadly distributed across the eastern United States. They once
occupied grasslands and tallgrass prairies of the Upper Midwest and Northeast, but most grasslands and prairies
have been lost, degraded, or fragmented by conversion to other uses. Bumble bees need areas that provide
nectar and pollen from flowers, nesting sites (underground and abandoned rodent cavities or clumps of grasses),
and overwintering sites for hibernating queens (undisturbed soil).
Rusty patched bumble bees live in colonies that include a single queen and female workers. The colony produces
males and new queens in late summer. Queens are the largest bees in the colony, and workers are the smallest.
All rusty patched bumble bees have entirely black heads, but only workers and males have a rusty reddish patch
centrally located on the back.
This species is listed as a historic occurrence for Mecklenburg County, and may be an extant record.
Michaux's Sumac
Michaux's sumac is a non-poisonous, low -growing, deciduous, densely hairy shrub. The erect stems grow from an
underground rhizome to a height of one to three feet. The compound leaves are alternate and divided into long
rows of 9 to 13 stalkless leaflets. The leaflets are 1.6 to 3.5 inches long, oblong, winged at the base, dull on the
top, hairy on the bottoms, with toothed edges. The terminal leaflet has a two inch long winged petiole. Flowers
grow at the top of the plant in a dense, erect cluster, colored greenish -yellow to white, and are four -to five -parted.
Fruit are hairy reddish drupes, each containing one seed.
Leaves emerge in April to May, flowering occurs April to June, and fruiting occurs August to October with fruits
persisting for several months. These plants are generally dioecious. Michaux sumac has been known to produce
male flowers one year and female flowers the next. Other individuals are monoecious with both male and female
flowers at one time. Usually less than half of the stems in a subpopulation do not flower in a given season. Even
though fruit may be plentiful, seed viability is low. This may be a result of self -incompatibility or hybridization with
other Rhus. This species usually produces asexually from thick, shallow horizontal rhizomes.
Michaux sumac prefers sandy, loamy swales and depressions, acidic and circumneutral uplands, and rocky open
woods. It grows best where disturbance has maintained an open area. Michaux sumac has been found along
roadsides, in powerline clearings, and areas where forest canopies have been opened up by blowdowns and/or

hurricane damage. Episodic fires accentuate habitat for this species and reduce hardwood encroachment, recycle
nutrients, and aid regeneration of longleaf pine/wiregrass communities. Potential habitat for Michaux sumac exists
in the utility easement. However, field review did not identify populations of Michaux sumac.
Schweinitz's Sunflower
Schweinitz's sunflower is a perennial herb in the aster family that generally grows up to five feet in height. This
plant has tuberous roots, with each stem attached to a single tuberous root. The stems are scabrous (rough) and
generally reddish in color. The leaves are soft pubescent below and scabrous on the upper surface. The ray
flowers are yellow, while the disk flowers are purplish. Schweinitz's sunflower generally blooms during the month
of September. The habitat of Schweinitz's sunflower is open woods, roadsides, and powerline easements, often
on basic soils with bare spots or a gravel component. The preferred sites are characterized by abundant sunlight
and little competition in the herbaceous layer.
Schweinitz's sunflower is listed as a current record for Mecklenburg County. The project area contains suitable
habitat for Schweinitz's sunflower within portions of the project area that consist of the powerline easement.
However, field review did not identify any populations of Helinathus species, including Schweinitz's sunflower.
Smooth Coneflower
Smooth coneflower is a perennial herb growing to a height of one and one-half to three feet tall. This species
grows from a thick, vertical root. The stems of smooth coneflower are smooth. The stems have few leaves, of
which the largest are the basal leaves. The basal leaves are lance -ovate to elliptical, coarsely serrate, and smooth
above and below. The basal leaves are attached by long, slender petioles, while the smaller leaves are attached
with shorter petioles. The smooth coneflower's flowering period occurs from May to July. The flower heads are
normally solitary, located at the terminal part of the stem, with drooping rays ranging from five to eight
centimeters long. The flower is light pink to purplish in color.
Smooth coneflower prefers open woods associated with red cedar, meadows, and cleared utility and road
easements. The species forms small stands within open, grassy woodlands and cedar barrens. The species prefers
basic or circumneutral soils. This species requires abundant sunlight, little herbaceous and shrub competition and
periodic disturbances such as fire. Smooth coneflower was not identified within the project area during the field
review.
Historic Resources
Review of the NC State Historic Preservation Office (SHPO) GIS web mapping service indicates that the closest
documented site eligible for inclusion on the National Register of Historic Places is Kimbrell's Furniture Store (Site
MK2157), located approximately 0.45 -mile northwest of the project area. Accordingly, the project should have no
effect on historic resources.
Avoidance and Minimization
The project design incorporated measures to limit the amount of permanent streambank disturbance to less than
150 If. The resultant design and proposed impacts are considered the minimum amount necessary to safely
0

provide long-term stabilization to the eroding streambank and protect the important adjacent infrastructure.
Impacts will be minimized by Duke's use of appropriate erosion and sediment control measures during
construction, utilizing high -visibility fencing to demarcate adjacent areas that are to remain undisturbed, and by
conducting a pre -construction meeting to review applicable permit conditions prior to construction.
Because the project will result in permanent impacts to less than 150 If of stream bank, and there will be no
wetland impacts, we do not anticipate that purchase of wetland mitigation credit will be required.

3j. Comments:
Permanent impacts to the right bank of S1 will be limited to 148 LF. Additonal temporary impacts identified in the
table will result from placement of coffer dams upstream and downstream of the work areas in order to establish a
clean -water bypass and dry work area.
E. Impact Justification and Mitigation
1. Avoidance and Minimization
1a. Specifically describe measures taken to avoid or minimize the proposed impacts in designing the project:*

The project design incorporated measures to limit the amount of permanent streambank disturbance to less than
150 If. The resultant design and proposed impacts are considered the minimum amount necessary to safely
provide long-term stabilization to the eroding streambank and protect the important adjacent infrastructure.
1b. Specifically describe measures taken to avoid or minimize the proposed impacts through construction techniques:*
Impacts will be minimized by Duke's use of appropriate erosion and sediment control measures during
construction, utilizing high -visibility fencing to demarcate adjacent areas that are to remain undisturbed, and by
conducting a pre -construction meeting to review applicable permit conditions prior to construction.

RE: Woodlawn Substation Streambank Stabilization
Dear Joey Lawler:
Secretary Susi H. Hamilton
NCNHDE-6758
The North Carolina Natural Heritage Program (NCNHP) appreciates the opportunity to provide information
about natural heritage resources for the project referenced above.
Based on the project area mapped with your request, a query of the NCNHP database, indicates that there are
no records for rare species, important natural communities, natural areas, and/or conservation/managed areas
within the proposed project boundary. Please note that although there may be no documentation of natural
heritage elements within the project boundary, it does not imply or confirm their absence; the area may not have
been surveyed. The results of this query should not be substituted for field surveys where suitable habitat exists.
In the event that rare species are found within the project area, please contact the NCNHP so that we may
update our records.
The attached `Potential Occurrences' table summarizes rare species and natural communities that have been
documented within a one -mile radius of the property boundary. The proximity of these records suggests that
these natural heritage elements may potentially be present in the project area if suitable habitat exists. Tables of
natural areas and conservation/managed areas within a one -mile radius of the project area, if any, are also
included in this report.
If a Federally -listed species is found within the project area or is indicated within a one -mile radius of the project
area, the NCNHP recommends contacting the US Fish and Wildlife Service (USFWS) for guidance. Contact
information for USFWS offices in North Carolina is found here:
https://www.fws.gov/offices/Directory/ListOffices.cfm?statecode=37.
Please note that natural heritage element data are maintained for the purposes of conservation planning, project
review, and scientific research, and are not intended for use as the primary criteria for regulatory decisions.
Information provided by the NCNHP database may not be published without prior written notification to the
NCNHP, and the NCNHP must be credited as an information source in these publications. Maps of NCNHP
data may not be redistributed without permission.
The NC Natural Heritage Program may follow this letter with additional correspondence if a Dedicated Nature
Preserve, Registered Heritage Area, Clean Water Management Trust Fund easement, or Federally -listed
species are documented near the project area.
If you have questions regarding the information provided in this letter or need additional assistance, please
contact Rodney A. Butler at rod ney.butler&Dncdcr.gov or 919-707-8603.
Sincerely,
NC Natural Heritage Program
