Mallard Creek Reuse Line Extension and Toby Creek Outfall Improvements
Mecklenburg County, NC
CWS Project No. 2019-0234
Dear Mr. Shaeffer and Mr. Johnson,
The Mallard Creek Reuse Line Extension and Toby Creek Outfall Improvements project limits
consist of an approximately 60-foot wide, 8,200-foot long corridor along Toby Creek, and an
approximately 40-foot wide, 10,400-foot long corridor along Mallard Creek (Figures 1 and 2,
Attachment A). On behalf of the Charlotte Water, Stantec has subcontracted Carolina Wetland
Services, Inc. (CWS) to provide Section 404/401 permitting services for this project. An executed
Agent Authorization Form is attached (Attachment B).
On behalf of Charlotte Water, CWS is submitting a Pre -Construction Notification pursuant to
Nationwide Permit No. 12 to the U.S. Army Corps of Engineers and Water Quality Certification No.
4133 to the North Carolina Division of Environmental Quality (NCDEQ) for proposed impacts to
jurisdictional waters of the U.S. associated with sewerline installation along Toby Creek near the
UNC Charlotte Campus and water reuse line installation along both Toby Creek and Mallard Creek.
This PCN includes a wetland delineation for the Toby Creek Outfall study area. No Jurisdictional
Determination is requested at this time. Wetland delineation for the Mallard Creek Reuse Line
easement was submitted to the USACE by Hazen and Sawyer on February 27, 2019.
Charlotte Water proposes purchasing the required compensatory mitigation credits from City of
Charlotte Umbrella Stream and Wetland Mitigation Bank and Division of Mitigation Services (DMS)
in -lieu fee program. DMS credits will be used to supplement as the Umbrella Mitigation bank does
not have all the required credits within the service area. The credit reservation letters are included
in Attachment I.
A copy of the PCN application is being provided to the North Carolina Division of Environmental
Quality (NCDEQ) with a check of $570 for the 401 Water Quality Certification approval fee.

3. Project Description
3a. Describe the existing conditions on the site and the general land use in the vicinity of the project at the time of
this application:
The Mallard Creek Reuse Line Extension and Toby Creek Outfall Improvements project limits consist of an approximately
60-foot wide, 8,200-foot long corridor along Toby Creek, and an approximately 40-foot wide, 10,400-foot long corridor along
Mallard Creek (Figures 1 and 2, Attachment A).
The project area consists of undeveloped forest and maintained herbaceous areas for athletic fields, public areas, and
power easements. Several roads transect the project area. On -site elevations range from 580-630 feet above mean sea
level (Figure 2). Land cover within the project area consists of deciduous forest, developed open space, herbaceous areas,
woody wetlands, and emergent herbaceous wetlands (Figure 3).
Land use in the vicinity of the project consists of residential neighborhoods, retail centers, a stone quarry, undeveloped land,
and land and facilities associated with the University of North Carolina at Charlotte (UNCC).
According to the United States Department of Agriculture - Natural Resources Conservation Service (USDA-NRCS) Web
Soil Survey of Mecklenburg County (Figure 4) and the NRCS 1976 Soil Survey for Mecklenburg County (Figure 5), current
and historic on -site soils consist of six different soil types. Of the on -site soils, Monocan loam (MO) is listed on the Web Soil
Survey as containing hydric inclusions.
A review of the National Wetlands Inventory (NWI) GIS layer depicts several potential wetland features within the project
limits (Figure 6, attached).
The jurisdictional waters of the U.S. within the Toby Creek Outfall portion are depicted in Figure 7. Delineation Maps 1-8,
prepared by Hazen and Sawyer, depict the jurisdictional waters of the U.S. within the Mallard Creek Reuse Line Extension.
3b. List the total estimated acreage of all existing wetlands on the property: 1.95 ac.
3c. List the total estimated linear feet of all existing streams (intermittent and perennial) on the property: 869 If perennial, 407
If intermittent
3d. Explain the purpose of the proposed project:
Toby Creek Outfall Improvements:
The Toby Creek Outfall Improvements project involves replacement of the main sewer line ("Outfall") running along Toby
Creek. This project is needed due to aging sewer infrastructure in the Toby Creek drainage basin. In addition, the
pipelines are experiencing additional flows due to rapid growth, which results in the need to increase sanitary sewer
capacity. The new sanitary sewer outfall will be designed and constructed within the project corridor to address current and
projected sewer demands.
The Phase I of this project is approximately 1.5 miles long and located along Toby Creek, near the UNC Charlotte campus,
extending from North Tryon Street to E WT Harris Boulevard. The Toby Creek Outfall Improvements Phases II and III will
likely occur within the next decade, but after the current Nationwide Permits have expired.
Page 3 of 20
PCN Form — Version 1.4 January 2009

The easement location for these phases have not been determined yet. See the overview in the Attachment F for the
approximate location of the future phases.
Mallard Creek Reuse Line Extension
The purpose of the project is to provide reuse water to current and future customers located along the project corridor,
including UNC Charlotte. City of Charlotte anticipates that development of the currently undeveloped areas within the
project area will occur and that connection of some of the new developments to the reuse line for non -potable water
sources, such as irrigation, will also happen. Approximately 3.5 miles of water reuse line will be installed along Mallard
Creek and Toby Creek.
An approximately 2 mile long, 40-foot wide water reuse line easement extends from Salisbury Street to North Tryon Street
along Mallard Creek. The water reuse line and the proposed sewerline will be running parallel to each with each other
along Toby Creek (see the Toby Creek Outfall Improvements). The easement width for the reach along Toby Creek is 60
feet to provide enough space for the construction and maintenance of these two utility lines.
3e. Describe the overall project in detail, including the type of equipment to be used:
Page 4 of 20
PCN Form — Version 1.4 January 2009

Project Overview
This project will include approximately 1.5 miles of sewerline installation along Toby Creek near the UNC Charlotte Campu!
and approximately 3.5 miles of water reuse line installation along both Toby Creek and Mallard Creek.
Under Nationwide Permit (NWP) No. 12, the project proposes six permanent and 19 temporary utility line stream crossings.
Additionally, the project proposes 0.50 acre of temporary wetland impacts associated with the utility line installation and
construction access, and 1.51 acre of permanent wetland impacts due to conversion from forested wetlands to herbaceous
for permanent maintenance corridor.
The proposed impacts are described in detail below.
Toby Creek Outfall
The proposed impacts for Toby Creek Outfall Improvement are illustrated in Attachment F.
Stream Impacts (T-S1 — T-S12)
All stream sewerline crossings within the Toby Creek Outfall portion are temporary and will be constructed via open trench.
The proposed temporary stream impacts total 666 linear feet. The temporary impacts were calculated based on the width
of the construction corridor and will include the temporary dewatering devices required in order to construct the sewerline in
the dry, temporary stream crossings, sewerline/waterline installation, and bank stabilization.
All areas disturbed by the work shall be re -graded, sloped for drainage and stabilized. Stabilization methods include
matting, seeding, and livestaking. See Sheet C13 for the bank stabilization detail (Attachment F).
Wetland Impacts (T-WI — T-W13)
The proposed permanent impacts to jurisdictional wetlands within Toby Creek Outfall total approximately 1.059 acre. The
proposed temporary impacts total 0.079 acre. All wetland crossings will be constructed via open trench.
Permanent impacts are the result of a permanently maintained easement through forested wetlands where forested
wetland will be mechanically cleared and permanently converted to maintained herbaceous wetland. Wetlands crossed to
access the new easements will be protected with timber mats. All impacted areas will be returned to their pre -construction
grades.
Note: As the sewerline and waterline will be located next to each other, the proposed construction and maintenance
easement within the Toby Creek outfall portion is 60 feet wide to allow enough space for the utility line installation and
maintenance. Therefore, Charlotte Water is Requesting a waiver for the Water Quality Certification #4133 Activity Specific
Condition No.4.
Mallard Creek Reuse Line
The proposed impacts for Mallard Creek Reuse Line Extension are shown in Attachment G.
Stream Impacts (M-S1 — M-S15)
All stream sewerline crossings will be constructed via open trench. The proposed temporary impact total 362 linear feet.
The temporary impacts were calculated based on the width of the construction corridor and will include the temporary
dewatering devices required in order to construct the sewerline in the dry, temporary stream crossings, sewerline/waterline
installation, and bank stabilization. The project also proposes six permanent stream crossing, resulting in 124 liner feet of
permanent stream impacts. Please see the Avoidance and Minimization Section for more information regarding the
permanent stream crossings. The detail for the permanent ford is included in the Attachment G.
All areas disturbed by the work shall stabilized. See Sheet D1 for the bank stabilization detail (Attachment G).
Wetland Impacts (M-WI — M-W8)
The proposed permanent impacts to jurisdictional wetlands within Mallard Creek Reuse Line project total approximately
0.454 acre. The proposed temporary impacts total 0.425 acre. All wetland crossings will be constructed via open trench.
Page 5 of 20
PCN Form — Version 1.4 January 2009

Permanent impacts are the result of a permanently maintained easement through forested wetlands where forested
wetland will be mechanically cleared and permanently converted to maintained herbaceous wetland. Wetlands crossed to
access the new easements will be protected with timber mats. All impacted areas will be returned to their pre -construction
grades.
Restoration of Forested Wetlands within Temporary Construction Corridor
All disturbed areas will be returned to original grade and seeded with a native seed mix within 90 days of completion of the
project." The seed mixture will not contain fescue. Planting of canopy and shrub species is not proposed. The undisturbe
canopy and shrub species abutting the project corridor will naturally reseed the non -maintained portions of the corridor and
will provide an assortment of existing and diverse native vegetation that matches the abutting species.
Construction equipment used will generally consist of track hoe excavators, track loaders, rubber tire loaders, off road
dump trucks, track crane, trench boxes, air compressors, generators, work trucks, and bypass pumps for the water
diversion.

D. Impact Justification and Mitigation
1. Avoidance and Minimization
1 a. Specifically describe measures taken to avoid or minimize the proposed impacts in designing project.
kvoidance of all impacts is possible only with a no -build alternative, which does not meet the need of the project. During design,
he project corridor was positioned to avoid jurisdictional wetlands, where feasible. However, as the project location is dictated by
tasting utility infrastructure and surrounding development, including UNC Charlotte facilities, greenway, etc., avoiding the streams
ind wetland within the project corridor is not feasible. Stream crossings were designed to reduce the limits of disturbance. All
:rossings are designed to be within 15 degrees of perpendicular.
permanent subsurface fords were designed to allow access to the pipe corridor while providing for a natural streambed.
'ermanent stream crossings are limited to six. The need for each permanent ford is described below.
Impact M-S3, Permanent Ford: This stream crossing is currently active and providing a permanent ford at this location will
arevent streambed degradation during continued use of the crossing for access. Since the stream crossing occurs on property
that is an active quarry, access through the quarry for inspection and repair of the pipe is not feasible. Additionally, since 1-485
aisects the project corridor between Pavilion Boulevard and the second pipe crossing of Mallard Creek, Charlotte Water has
,equested access to the pipe corridor on either side of 1-485.
Impact M-S5, Permanent Ford: This stream crossing is currently active and providing a permanent ford at this location will
prevent streambed degradation during continued use of the crossing for access. Since the stream crossing occurs on property
that is an active quarry, access through the quarry for inspection and repair of the pipe is not feasible.
Impact M-S8, Permanent Ford: This is an active access point and is noted on the plans as Access Point 6. Construction of a
qew access road to avoid a permanent crossing at Stream S-4 is anticipated to result in impacts to jurisdictional areas in excess
of proposed impacts due to streams and wetlands in proximity to the corridor. Providing a permanent ford at this location will
prevent streambed degradation during continued use of the crossing for access.
Impact M-S10, Permanent Ford: Access from Highway 29 will not be allowed by NCDOT due to high traffic volume. However, if
access was from Highway 29 on the north side of the Duke Energy transmission line, a new permanent access easement that
aarallels and is outside of the existing Duke Energy easement would be required. The area in which the access easement would
ae located consists of a forested wetland that would be converted to an access road.
If access was obtained on the south side of the Duke Energy transmission line, the access corridor would follow the existing
sanitary sewer easement, which would end the new permanent access between two streams (Streams S-6 and S-7). The reuse
wipe corridor crosses both Streams S-6 and S-7 versus crossing downstream below the confluence of the two streams due to a
future gravity sewer being installed between the reuse line described herein and an existing sanitary sewer.
Impact M-S12, Permanent Ford: Same as Permanent Impact Justification for M-S10.
Impact M-S15, Permanent Ford: Due to the pipe corridor being between Mallard Creek and a UT to Mallard Creek, it is not
feasible to have permanent access to the reuse pipe without crossing either Mallard Creek, which is not feasible due to the
steepness of the stream banks, or the UT to Mallard Creek, which is proposed.

PCN Form — Version 1.4 January 2009

1 b. Specifically describe measures taken to avoid or minimize the proposed impacts through construction techniques.
Proper sediment and erosion control measures will be used to minimize disturbances to downstream waters. Anti -seep collars
will be installed at the downstream wetland boundary and every 150 feet up the gradient until the relief sewer exits the wetland.
II channel work will be constructed in the dry in accordance with Water Quality Certification No. 4133.
II impacted areas will be returned to their pre -impact grades. All impacted stream banks shall be permanently stabilized with
matting, seeding, and livestaking. No rip rap will be utilized for bank stabilization.
Impacts to jurisdictional areas during construction will be limited to the extent feasible by performing as much work as is possible
from upland areas. In areas of impact, silt fencing will be placed upgradient of the jurisdictional areas and all construction activity
will be performed upgradient of the silt fencing. All disturbed areas will be returned to original grade and seeded with a native
seed mix within 90 days of completion of the project. Timber mats will be used where appropriate in wetland areas. Excavation of
the pipe trench will be performed as prescribed by the USACE in jurisdictional areas and side casting of excavated material into
abutting wetland areas will be avoided to the extent feasible.

BOUNDARY
INSTALLATION:
1. WHERE FEASIBLE, PLACE MATS IN A LOCATION THAT WILL MINIMIZE THE AMOUNT
NEEDED FOR THE WETLANDS CROSSING. . . . . . . . . . . . .
2. INSTALL ADEQUATE EROSION AND SEDIMENT CONTROLS AT APPROACHES TO MATS
TO PROMOTE A SMOOTH TRANSITION TO, AND MINIMIZE SEDIMENT TRACKING ONTO,
MATS.
3. MATS SHOULD BE PLACED ALONG THE TRAVEL WAY SO THAT THE INDIVIDUAL TIMBERS
ARE RESTING PERPENDICULAR TO THE DIRECTION OF TRAFFIC. NO GAPS SHOULD EXIST
BETWEEN TIMBERS.
MAINTENANCE:
1. MATTED WETLAND CROSSINGS SHOULD BE MONITORED TO ASSURE CORRECT
FUNCTIONING OF THE MATS. INSPECT MATS DURING USE. LOOK FOR ANY DEFECTS OR
STRUCTURAL PROBLEMS.
2. MATS WHICH BECOME COVERED WITH SOILS OR CONSTRUCTION DEBRIS SHOULD BE
CLEANED AND THE MATERIALS REMOVED AND DISPOSED OF IN AN UPLAND LOCATION.
THE MATERIAL SHOULD NOT BE SCRAPED AND SHOVELED INTO THE WETLANDS AREA.
3. MATS WHICH BECOME IMBEDDED MUST BE RESET OR LAYERED TO PREVENT MUD FROM
COVERING THEM OR WATER PASSING OVER THEM.
DIREC TION
OF TRAVEL
REMOVAL:
1. MATTING SHOULD BE REMOVED BY "BACKING" OUT OF THE SITE, REMOVING MATS ONE PLAN
AT A TIME. ANY RUTTING OR SIGNIFICANT INDENTATIONS IDENTIFIED DURING MAT
REMOVAL SHOULD BE REGRADED IMMEDIATELY, TAKING CARE NOT TO COMPACT SOILS. TIMBERS MAY BE BOLTED
2. MATS SHOULD BE CLEANED BEFORE TRANSPORT TO ANOTHER WETLAND LOCATION TO OR CABLED TOGETHER TO
REMOVE SOIL AND ANY INVASIVE PLANT SPECIES SEED STOCK OR PLANT MATERIAL. MAKE UP MAT SECTIONS.
3. CLEANING METHODS MAY INCLUDE BUT ARE NOT LIMITED TO SHAKING OR DROPPING
MATS IN A CONTROLLED MANNER WITH A PIECE OF MACHINERY TO KNOCK OFF
ATTACHED SOIL AND DEBRIS, SPRAYING WITH WATER OR AIR, AND SWEEPING.

BRIDGEMAT NOTES
BRIDGEMATS ARE HEAVY WOOD OR STEEL PANELS PLACED OVER A STREAM OR DITCH
CHANNEL, USUALLY FOR TEMPORARY CROSSING. OTHER NAMES INCLUDE DRAGLINE MATS,
SKIDDER BRIDGES OR PONTOONS. WHEN BRIDGEMATS ARE CAREFULLY INSTALLED, USED,
AND REMOVED, THEY TYPICALLY DO A VERY GOOD JOB OF PROTECTING WATER QUALITY.
BMPS FOR BRIDGEMATS
1. WHEN SITE CONDITIONS ALLOW, SELECT A STREAM CROSSING LOCATION THAT HAS THESE
CHARACTERISTICS:
- NARROW CHANNEL WIDTH.
- FIRM, STABLE STREAMBANKS.
- SOLID FOOTING ON EITHER SIDE TO SUPPORT BRIDGEMATS AND EQUIPMENT.
- HIGH, LEVEL GROUND ON EACH SIDE,
2. CREATE A SOLID -SURFACE CROSSING THAT PROVIDES A BARRIER OVER THE CHANNEL TO
MINIMIZE DEBRIS, SOIL, AND OTHER MATERIALS FROM FALLING INTO THE WATER.
3. KEEP EQUIPMENT OUT OF THE CHANNEL DURING INSTALLATION AND REMOVAL OF THE
CROSSING UNLESS DOING SO IS NECESSARY FOR HANDLING THE BRIDGEMATS.
MINIMIZE THE AMOUNT OF OVER -HANG FROM LOGS, TREES, OR TRUCKS/TRAILERS THAT
MAY DISTURB THE CHANNEL OR APPROACHWAYS.
4. CONTROL RUNOFF AND/OR CAPTURE SEDIMENT ON THE APPROACHWAYS,
5. AS NEEDED, PERIODICALLY INSPECT THE CROSSING AND TAKE ACTION TO PROVIDE FOR
SAFETY WHILE PROTECTING WATER QUALITY FROM RUNOFF, DEBRIS, SOIL, OR OTHER
POTENTIAL POLLUTION FACTORS.
6. STABILIZE THE APPROACHWAYS AND CROSSING LOCATION IN ACCORDANCE WITH
FPG .0203 AND .0209 OF THE NC FOREST SERVICE.

Mecklenburg County, North Carolina
CWS Project No. 2019-0234
Dear Mr. Stout,
Stantec has contracted Carolina Wetland Services, Inc. (CWS) to provide a protected species
habitat assessment for the Mallard Creek Reuse Line Extension and Toby Creek Outfall
Improvements project. The Mallard Creek Reuse Line Extension and Toby Creek Outfall
Improvements project limits consist of an approximately 60-foot wide, 8,200-foot long corridor
that begins northeast of the University City Boulevard and East W.T. Harris Boulevard
intersection, and extends northward along Toby Creek to just southwest of the North Tryon
Street and the East Mallard Creek Church Road intersection. Just south of the North Tryon
Street and East Mallard Creek Church Road intersection there is an additional trunk that
branches off of the main corridor that will be used for a water reuse line. This trunk is
approximately 40-feet wide and 10,400-feet long, and extends northeast along Mallard Creek to
just south of the North Tryon Street and Pavilion Boulevard intersection in Charlotte, North
Carolina (Figure 1).
Methods
In -office Desktop Review
To determine which protected species are listed as occurring or potentially occurring within the
project vicinity and prior to conducting the on -site field investigation, CWS consulted the United
States Fish and Wildlife Service (USFWS) Endangered and Threatened Species and Species of
Concern by County for North Carolina online database for Mecklenburg County'. In addition,
CWS performed a data review using the North Carolina Natural Heritage Program (NCNHP)
Data Explorer on November 26, 2019 to determine if any record occurrences of federally -listed,
candidate endangered, threatened species, or critical habitat are located within the project
limits.

Typical habitat requirements for listed species was discerned from multiple USFWS3 and
NCNHP4 online resources including, but not limited to, specific USFWS species profiles,
recovery plans, NCNHP's Guide to Federally Listed Endangered and Threatened Species of
North Carolina, and List of the Rare Plant Species of North Carolina. United States Department
of Agriculture - Natural Resources Conservation Service (USDA-NRCS) Web Soil Survey of
Mecklenburg County5 and aerial imagery were also reviewed for potential habitat communities
of listed species within the project vicinity (Figures 2 and 3).
Field Survey
CWS scientists Megan Shelton, WPIT6, Project Scientist, Kerry Wright, Project Scientist, Amie
Hoy, Staff Scientist III, and Ian Dunning, Staff Scientist I conducted a pedestrian habitat
assessment of the project area on August 20, and October 22 and 23, 2019. Potential habitats
for potentially occurring federally -protected species that were identified during the desktop
review were assessed in the field for the quality of physical and/or biological features essential
to the conservation of the applicable species. Additionally, during the pedestrian habitat
assessment, areas were reviewed for applicable federally protected species. However, formal
surveys were not conducted for the occurence of protected species. Identification references
for natural communities include the National Land Cover Database (2011)7.
Results
Based on the NCNHP data explorer review, there are two occurrences of Schweinitz's sunflower
within a one -mile radius of the project limits (Attachment A). The USFWS lists seven federally
protected species for Mecklenburg County (Table 1). An official species list has not been
obtained from the USFWS Asheville Field Office.

Three terrestrial community types were identified within the project area during the field survey.
These community types consist of deciduous, herbaceous and low intensity development
(Figure 3). Of the identified on -site community types, the forested and herbaceous areas are
considered potential habitat for federally threatened or endangered species that could
potentially occur within the project limits. A brief description of each species habitat
requirements and determination of effect findings are listed below by species.
Schweinitz's sunflower (Helianthus schweinitzii)
Habitat Description:
Schweinitz's sunflower is a perennial herb with yellow rays and yellow centers. They
can reach heights of five feet. Populations are limited to the piedmont of North and
South Carolina. It has been listed as an Endangered species under the ESA since
1991.8 The typical habitat for this plant includes roadsides, old pastures, transmission
line right-of-ways, open areas, either natural or human -maintained habitats, or edges of
upland woods. Major characteristics of soils associated with suitable Schweinitz's
sunflower habitat include thin soils, soils on upland interstream flats or gentle slopes,
soils that are clay like in both composition and texture (and often with substantial rock
fragments), soils that have a high shrinkage swell capacity, and those which vary over
the course of the year from very wet to very dry.
Biological Analysis:
A NCNHP data record review revealed that there are two occurrences within one mile of
the project limits. A desktop review of the site was conducted on October 21, 2019, and
determined that the Enon and Mecklenburg soil series that are associated with
Schweinitz's sunflower habitat are found on -site along the light rail line in the central
s United States Fish and Wildlife Services. 1991. Endangered and Threatened Wildlife and Plants; Helianthus schweinitzii

portion of the project limits. This area is occasionally maintained through the practices
of mowing, and provides marginal habitat. This area is maintained just infrequent
enough that natural conditions that could support Schweitz;s sunflower were present
(Photograph 7). The other herbaceous areas throughout the project limits consist of the
Monocan loam soil series, which is not conducive to Schweinitz's sunflower habitat. In
addition, these areas are heavily maintained through the practices of mowing and
pesticide application, which is not supportive of Schweinitz's sunflower (Photographs 3
and 5). The on -site forested areas do not provide adequate sunlight and do not contain
the proper soil series to support Schweinitz's sunflower (Photographs 1, 10 and 11). On
October 22, 2019, CWS visited a nearby reference population, and noted that all plant
parts of the Schweinitz's sunflower were identifiable and the plant was approximately
five feet tall (Photograph 13). No individuals of Schweinitz's sunflower were observed in
the study area during the field review. As the survey was conducted during the optimal
survey window of late August to October and mature vegetation was present,
Schweinitz's sunflower would have been seen if present. Therefore, because no
individuals of Schweinitz's sunflower were observed during the optimal survey window,
CWS concludes that this project will have no effect on the Schweinitz's sunflower.
Smooth coneflower (Echinacea laevigata)
Habitat Description:
Smooth coneflower is a tall, perennial herbaceous plant found in areas with abundant
sunlight where competition in the herbaceous layer is minimal. It has been federally
listed as Endangered under the ESA since 1992.9 Typical habitat for this plant includes
meadows, open woodlands, the ecotonal regions between meadows and woodlands,
cedar barrens, dry limestone bluffs, clear cuts, and roadside and utility rights -of -way. In
North Carolina, the species normally grows in magnesium- and calcium- rich soils
associated with gabbro and diabase parent material, and typically occurs in Iredell,
Misenheimer, and Picture soil series. It grows best where there is abundant sunlight,
little competition in the herbaceous layer, and periodic disturbances (e.g., regular fire
regime, well-timed mowing, careful clearing) that prevents encroachment of
shade -producing woody shrubs and trees. On sites where woody succession is held in
check, it is characterized by a number of species with prairie affinities.
Biological Analysis:
A NCNHP data record review revealed that there are no current occurrences for this
species within the project limits, or within a one -mile radius of the project (Attachment A).
The majority of the project limits are forested, which does not provide the abundant
sunlight the smooth coneflower requires. In addition, Iredell, Misenheimer, and Picture
soil series commonly associated with the smooth coneflower are not found within the
project limits.10 Due to the lack of habitat and known occurrences, CWS concludes that
this project will have no effect on smooth coneflower.

Michaux's sumac (Rhus michauxii)
Habitat Description:
Michaux's sumac is a rhizomatous shrub. It is densely hairy with compound leaves
exhibiting evenly -serrated leaflets. Flowers are small, greenish to white, in terminal
clusters. Fruits are red drupes produced from August to October. It has been listed as
an Endangered species under the Endangered Species Act (ESA) since 1989.11 It is
found on the coastal plains of Virginia to Florida, with most populations occurring in
North Carolina. It prefers sandy or rocky open woods with basic soils, as well as,
highway right-of-ways, roadsides, or edges of artificially -maintained clearings.
Biological Analysis:
A NCNHP data record review revealed that there are no current occurrences for this
species within the project limits, or within a one -mile radius of the project (Attachment A).
Disturbed open areas conducive to early -succession species are not present in the
project area. The Monacan loam soil series that covers the majority of the site is too
acidic to provide suitable habitat for Michaux's sumac. Additionally, there are no current
records of this species within Mecklenburg County12. Due to the lack of habitat and
known occurrences, CWS concludes that this project will have no effect on
Michaux's sumac.
Carolina heelsplitter (Lasmigona decorata)
Habitat Description:
The Carolina heelsplitter was historically known from several locations within the
Catawba and Pee Dee River systems in North Carolina and the Pee Dee and Savannah
River systems, and possibly the Saluda River system in South Carolina. In North
Carolina, the species is now known only from a handful of streams in the Pee Dee and
Catawba River systems. The species exists in very low abundances, usually within 6
feet of shorelines, throughout its known range. The general habitat requirements for the
Carolina heelsplitter are shaded areas in large rivers to small streams, often burrowed
into clay banks between the root systems of trees, or in runs along steep banks with
moderate current. Recently, the Carolina heelsplitter has been found is in sections of
streams containing bedrock with perpendicular crevices filled with sand and gravel, and
with wide riparian buffers."
Biological Analysis:
There are ten perennial streams on -site, including Mallard Creek and Toby Creek. This
portion of Mallard Creek has been severely impaired by stormwater runoff from the
surrounding university14. The runoff has resulted in high nutrient levels and high
turbidity, which is not supportive of the Carolina heelsplitter. Toby Creek is severely

which is not conducive to Carolina heelsplitter habitat. In addition, the other perennial
streams that drain into Toby and Mallard Creek are heavily embedded with silt and trash,
which is not suitable habitat for Carolina heelsplitter. All of the on -site perennial streams
are connected to downstream waters via large culverts, which is also not conducive for
Carolina heelsplitter (Photographs 2, 4, 6, 8, 9, and 12). Additionally, the NCNHP data
record review revealed that there are no current occurrences for this species within the
project limits, or within a one -mile radius of the project (Attachment A). Therefore, CWS
concludes that this project will have no effect the Carolina heelsplitter.
Rusty Patched Bumble Bee (Bombus affinis)
The Rusty patched bumble bee was listed as Endangered under the ESA in January 2016.95
Rusty patched bumble bees 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. According to USFWS guidance, "the rusty patched
bumble bee population has declined by approximately 90% or more. There are currently
records of Bombus affinis in isolated places within 13 states and 1 providence since 2000. In
these areas, surveys should only be completed by qualified biologists under the guidance of the
federal recovery/scientific permit under section 10(a)(1)(B) of the ESA. These surveyors must
also meet all applicable state permitting and reporting requirements. The presence of Bombus
affinis has been broken down into three zones. A high potential zone provides a reasonable
basis for describing where the species is likely to be present and where federal agencies and
others should consult with Fish and Wildlife Services to evaluate the potential effects of their
actions. A low potential zone buffers a high potential zone and are much less likely to support
existing populations. Scientists are hopeful that some of these low potential areas may contain
the bee, and they recommend that surveyors obtain a scientific recovery permit. The third zone
is the unoccupied zone. Scientists believe that the likelihood of finding the species in these
areas is so low that they do not recommend scientific recovery permits, unless a Bombus affinis
may have accidentally been collected.16 According to USFWS' Rusty Patched Bumble Bee
Interactive Map, Mecklenburg County is located within an unoccupied zone. Therefore, the
proposed project will have no effect on the Rusty -patched bumble bee.
Northern long-eared bat (Myotis septentrionalisI
The northern long-eared bat (NLEB) is one of the species of bats most impacted by the
white -nose syndrome disease. Summer habitat (roosting habitat) of the NLEB includes forests
and woodlots containing live trees and/or dead snags greater than three inches diameter at
breast height with cavities or crevices. Winter habitat (hibernacula) of the NLEB includes caves,
mines, rocky areas, or structures that mimic similar conditions such as culverts greater than
48-inch in diameter." The NLEB was listed as Threatened (T) on April 2, 2015.

Protected Species Assessment Report CWS Project No. 2019-0234
The forested areas within the property are potential habitats for the NLEB. A Standard Local
Operating Procedure for Endangered Species Act Compliance (SLOPES) was established for
NLEB between the USFWS Asheville and Raleigh Ecological Offices and the United States
Army Corps of Engineers (USACE), Wilmington District, on January 31, 2017.18 This SLOPES
defines how the USACE will make determinations of effect to the NLEB on projects in which the
USACE is the lead federal agency. Alternative Local Procedure 2 (ALP 2) applies for the
Mallard Creek Reuse Line Extension and Toby Creek Outfall Improvements project as the action
area is within range of the NLEB,19 the action area is located outside of a red 12-digit HUC as
defined by the Asheville Ecological Services Field Office 2' and consultation by the USACE is
required on other listed species or critical habitat.
The final 4(d) rule exempts incidental take of NLEB associated with activities that occur greater
than 0.25 miles from a known hibernaculum site and greater than 150 feet from a known,
occupied maternity roost from June 1-July 31. In accordance with ALP 2 and the final 4(d) rule
(effective as of February 16, 2016), any incidental take that may result from associated activities
is exempt under the 4(d) rule. Therefore, this project is exempt under the 4(d) rule.
Bald eagle (Haliaeetus leucocephalus)
The Bald and Golden Eagle Protection Act'21 enacted in 1940, prohibits anyone without a permit
issued, from "taking" bald eagles, including their parts, nests, or eggs. Habitat for the bald
eagle includes cliffs and forested areas typically within 1.0 mile of estuaries, large lakes,
reservoirs, rivers, seacoast, and as they become more abundant, stands of undisturbed forest.
A desktop-GIS assessment of the project study area, as well as, the area within a 1 mile radius
of the project limits, was performed on August 8, 2019 using 2019 color aerials. No water
bodies large enough or sufficiently open to be considered potential feeding sources were
identified. Since there was no foraging habitat within the review area, a survey of the project
study area and the area within the project limits was not conducted. Additionally, a review of the
NCNHP database on August 8, 2019 revealed no known occurrences of this species within 1.0
mile of the project study area. Due to the lack of habitat and known occurrences, CWS
concludes that this project will have no effect on this species.
Summary
Based on the literature search and the results of the on -site assessment for suitable habitat of
federally -protected endangered, and threatened species, suitable habitat was not observed
within the project limits for smooth coneflower, Michaux's sumac, bald eagle, or Carolina
heelsplitter. Marginal habitat was observed for Schweinitz's sunflower. The project area is not
located within the currently occupied range of the rusty -patched bumble bee. CWS has
concluded that activities within the project area will not directly or indirectly jeopardize the
continued existence of Schweinitz's sunflower, smooth coneflower, Michaux's sumac, bald
eagle, rusty -patched bumble bee, and Carolina heelsplitter. Additionally, based on the project
area location, no tree removal activities will occur within a 150-foot radius of a known, occupied
NLEB maternity roost from June 1-July 31 and no trees will be removed within 0.25 miles of a

A biological assessment was not conducted for this project. All biological determinations of
effect represent the best professional opinion of CWS and are not official determinations of
effect. It is the responsibility of the lead federal agency to render an official determination of
effect. Should the lead federal agency agree with CWS's initial findings of no effect, then no
USFWS consultation is required to comply with Section 7 of the Endangered Species Act.
Should the lead federal agency's determination of effect differ from the findings of CWS, formal
or informal consultation with USFWS may be required.
Thank you for the opportunity to provide these services on this important project. Please do not

RE: Mallard Creek Reuse Line Extension and Toby Creek Outfall Improvements
Dear Megan Shelton:
The North Carolina Natural Heritage Program (NCNHP) appreciates the opportunity to provide
information about natural heritage resources for the project referenced above.
A query of the NCNHP database indicates that there are records for rare species, important natural
communities, natural areas, and/or conservation/managed areas within the proposed project
boundary. These results are presented in the attached `Documented Occurrences' tables and map.
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 documented within the project area or 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.ciov/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.
Also please note that 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 an occurrence of a Federally -listed species is 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 rodney.butlerC�ncdcr.gov or 919-707-8603.
Sincerely,
NC Natural Heritage Program

Expiration of Acceptance: 6/12/2020
Project: Mallard Creek Reuse Line Toby Creek Outfall County: Mecklenburg
The purpose of this letter is to notify you that the NCDEQ Division of Mitigation Services (DMS) is willing to
accept payment for compensatory mitigation for impacts associated with the above referenced project as
indicated in the table below. Please note that this decision does not assure that participation in the DMS in -
lieu fee mitigation program will be approved by the permit issuing agencies as mitigation for project impacts.
It is the responsibility of the applicant to contact permitting agencies to determine if payment to the DMS will
be approved. You must also comply with all other state, federal or local government permits, regulations or
authorizations associated with the proposed activity including G.S. § 143-214.11.
This acceptance is valid for six months from the date of this letter and is not transferable. If we have not
received a copy of the issued 404 Permit/401 Certification within this time frame, this acceptance will
expire. It is the applicant's responsibility to send copies of the permits to DMS. Once DMS receives a copy
of the permit(s) an invoice will be issued based on the required mitigation in that permit and payment must
be made prior to conducting the authorized work. The amount of the in -lieu fee to be paid by an applicant is
calculated based upon the Fee Schedule and policies listed on the DMS website.
Based on the information supplied by you in your request to use the DMS, the impacts for which you are
requesting compensatory mitigation credit are summarized in the following table. The amount of mitigation
required and assigned to DMS for this impact is determined by permitting agencies and may exceed the
impact amounts shown below. _
River Basin 1 Impact Location Impact Type Impact Quantity
