Dear Ms. Amschler and Ms. Higgins:
On behalf of Charlotte -Mecklenburg Storm Water Services (CMSWS), S&ME, Inc. (S&ME) is submitting this
Pre -Construction Notification (PCN) for impacts to waters of the U.S. in accordance with Department of
the Army Nationwide Permit (NWP) 3 (Maintenance) and NWP 27 (Aquatic Habitat Restoration) along
with supporting documentation for preliminaryjurisdictional determination of the on-site jurisdictional
boundaries, located in Charlotte, Mecklenburg County, North Carolina. The proposed project will
primarily involve aquatic habitat enhancement activities (authorized under NWP 27) of an unnamed
tributary of McAlpine Creek, which will result in permanent impact (no loss of waters) of 253 linear feet (If)
involving the enhancement of riffle stream structure, the placement of in -stream habitat structures, and
the modification of the stream bed and banks to restore stream meanders. Approximately 26 If of
permanent loss will occur due to the reduction in overall stream channel sinuosity, associated with the
stream channel improvements. The NWP 3 Maintenance will involve the replacement of 25 If of existing
pipe that was installed by the homeowner, and the installation of 20 If of riprap apron. The proposed pipe
replacement, riprap apron installation, and improvements to the stream channel are necessary to address
severe erosion and prevent property loss.
Impacts proposed associated with the aspects of this project described herein are authorized under North
Carolina Division of Water Resources (DWR) Water Quality Certifications (WQC) Nos. 3883 and 3885. As
the proposed project will involve channel enhancement with greater than three structures per 100 feet of
stream bank, written concurrence from DWR is required for authorization under WQC 3885.

*.- Field Observations
On March 23, 2016, Mr. Darrin Peine of S&ME visited the site to verify the location and classification of
jurisdictional waters and note site conditions along the drainage system where disturbance associated
with the project is proposed. Stream and wetland assessments were conducted in accordance with DWR
and U.S. Army Corps of Engineers (USACE) guidelines. Results of the assessment are depicted on Figure 3
and representative photographs of the project area are included in Appendix II.
S&ME's field review of the project area identified one jurisdictional relatively permanent water (RPW)
exhibiting characteristics consistent with intermittent flow (Stream 1). The Stream 1 channel is a first order
intermittent tributary to McAlpine Creek with a watershed drainage area of approximately 0.03 square
miles (19.2 acres). Channel condition was poor as numerous areas along the channel were deeply incised
and with actively eroding banks. Bed material was largely made up of unconsolidated fine material,
hardpan clay, or non-native materials such as riprap or broken concrete. The riparian area was made up
largely of maintained or partially maintained residential yards. Non -maintained riparian areas adjacent to
Stream 1 were dominated by invasive understory and herbaceous vegetation such as Chinese privet
(Ligustrum sinense) and Japanese honeysuckle (Lonicera japonica). Land use adjacent to the stream and
throughout its watershed is largely made up of medium density maintained residential areas. The channel
originates at a storm sewer outfall (24 -inch high-density polyethylene pipe (HDPE)).
No wetlands were observed within the proposed project area. A USACE Wetland Determination Data
Form (Eastern Mountains and Piedmont Region) was completed to document uplands within the project
area, and is included in Appendix V.
CMSWS requests a Preliminary Jurisdictional Determination from the USACE in support of these findings;
as such, a completed USACE Jurisdictional Determination Request Form is included in Appendix IV.
Completed DWQ Stream Identification Form and a USACE Wetland Determination Form are included in
Appendix V.

Pre -Construction Notification: NWP Nos. 3 & 27
5447 Kerry Glen Lane Maintenance Project
Charlotte, Mecklenburg County, North Carolina
S&ME Project No. 4335-16-015 Phase 003
Proposed jurisdictional impacts associated with this project are detailed in the project plans and depicted
on Figure 4 — Proposed Jurisdictional Impacts. The purpose of this project is to repair and improve the
stability of the stream channel and minimize erosion from flooding.
The project involves installation of a proposed riprap apron that is approximately 20 ft in length and
between 4 — 6 feet wide that is to be installed at the outfall of the existing 24 -inch -diameter HDPE pipe
and the to be replaced 15 -inch reinforced concrete pipe (RCP), (sheet 3 of 4, project plan detail). The
proposed riprap apron will consist of riffle material (gradation of 2 —12 inch riprap, #57 stone and natural
cobble material), placed in the channel bed with riprap armored banks. The channel enhancements will
involve the grading and placement of five rock cross vanes, eight rock sills, and the installation of a total
of 93.5 If of constructed riffle, and the regrading of channel banks in order to generate a more stable
channel cross section. Project plan details of these structures are described on sheet 4 of the project
plans. Though proposed restoration measures will reduce overall channel sinuosity and the resulting
channel length by 26 If, this reduction is necessary in order to limit tree clearing, eliminate two hairpin
channel bends that are exhibiting excessive near -bank stress, and generate a stable high -gradient channel
within the available workspace.
All staging, excavation, stockpiling, and construction shall be contained within the existing right-of-way,
permanent storm drainage easement, and temporary construction easement (approximately 0.28 acre,
total). Work will be conducted in the dry through the use of cofferdams and pump-arounds. Graded
channel banks will be replanted with native riparian woody species. Upland areas disturbed due to work
will be reseeded. Typical construction equipment will be used, including backhoes and dump trucks.
Permanent loss of waters to approximately 26 If of Stream 1 will occur as a result of the new channel
alignment.
Protected Species
S&ME's consideration of potential protected species habitat began with a review of existing records
obtained from federal and state sources. The U.S. Fish & Wildlife Service (USFWS) list of federally -
protected species (updated April 2, 2015) was consulted for a listing of protected species documented
within Mecklenburg County, North Carolina. This review identified four plant species and three animal
species. Listed fauna and flora and their federal status are identified in Table 1.

As part of the protected species review, S&ME also reviewed the North Carolina Natural Heritage Program
(NCNHP) Geographic Information Systems (GIS) files of Element Occurrence (EO) and Natural Heritage
Areas available from NC OneMap. This review found no extant EOs of protected species on record within
a one -mile radius of the project area.
S&ME completed a field reconnaissance of the project area on March 23, 2016. The project area consists
of maintained lawn along with a narrow, lightly wooded riparian corridor of Stream 1. Riparian corridors
are not the preferred habitat for the plant species of concern, and none of the three listed plant species
were observed. The waters to be impacted are borderline intermittent/perennial and of poor habitat due
to surrounding urbanization; these streams would, therefore, be considered unsuitable for Carolina
heelsplitter. The activity will not significantly change the overall nature and function of the local forested
habitat, therefore the project may affect, but is not likely to adversely affect the northern long-eared bat.
Based on the level of continued maintenance and disturbance observed, the project area was not
considered to provide suitable habitat for protected species with a likelihood of occurring in Mecklenburg
County.
Cultural Resources
A digital copy of this PCN will be provided to the North Carolina State Historic Preservation Office (SHPO),
requesting that they review their records regarding cultural, archaeological, or historical resources in or
near the project area and to provide written comments regarding the interests of their agency. A review
of the SHPO's "HPOWEB" GIS Web Service indicated that there were no properties currently listed or
determined eligible for listing in the National Register of Historic Places within a mile radius of the project.
®ad Avoidance and Minimization
Impacts have been avoided and minimized to the extent practicable and have been limited to what is
necessary to facilitate storm water infrastructure upgrades and stream enhancement. Overall permanent
stream loss associated with maintenance aspects of this project have been limited to 20 If. Additional
placement of riprap was avoided through the use of natural channel design structures such as rock sills
and riffle construction, which will serve to stabilize the channel while also providing improvements to the
channel habitat. Efforts have been made to limit clearing of trees within the project corridor to the
minimum amount required for safe construction of the restoration channel, and tree protection measures
will be installed to safeguard trees within the limits of disturbance that are to remain.

S&ME
Charlotte, Mecklenburg County, North Carolina
S&ME Project No. 4335-16-015 Phase 003
To prevent sedimentation of downstream portions of the affected streams, construction will be conducted
in the dry through the use of coffer dams and pump-arounds. Temporary erosion and sediment control
measures placed in waters will be removed and the original grade restored upon completion of the
project. Banks affected by maintenance work will be matted, re -seeded and restored to stable bank
conditions.
®*.® Additional Regulatory Considerations
Efforts have been made to meet the conditions of NWP 3 and 27 as well as the regional conditions of the
NWPs and conditions associated with the North Carolina Water Quality Certifications (WQC) that
correspond to these NWPs (WQC 3883 and 3885).
Appropriate erosion and sediment control practices will be implemented to meet water quality turbidity
standards. Best Management Practices employed for the project will be in compliance with the most
recent version of the "North Carolina Sediment and Erosion Control Planning and Design Manual," and
the local governing authority. Impacts have been avoided and minimized, and appropriate measures will
be taken during construction to allow flow and circulation patterns of waters of the U.S. to remain
unaffected. Following construction, temporary sediment and erosion control structures will be removed
and disturbed areas adjacent to the work site will be restored to a stable grade and disturbed areas will be
appropriately seeded.
®*.* Mitigation
Based on conversations with the USACE for similar projects, we anticipate that mitigation will not be
required for this project due to minimal area or stream permanently impacted, the already highly
degraded status of impacted channel, and as appropriate avoidance and minimization procedures have
been implemented during the design phase of the project. Since efforts result in the loss of less than 150
If of stream bed and maintenance efforts have been designed to meet the ecological functions of the
stream and best serve the stream enhancement efforts, no further mitigation measures are proposed in
association with activities authorized under NWP 3. Though enhancement efforts associated with NWP 27
are designed to provide ecological uplift to Stream 1, CMSWS has opted to not seek mitigation credit for
these enhancements.

D. Impact Justification and Mitigation
1. Avoidance and Minimization
1a. Specifically describe measures taken to avoid or minimize the proposed impacts in designing project.
Impacts have been avoided and minimized to the extent practicable and have been limited to what is necessary to facilitate
storm water infrastructure upgrades and stream enhancement.
To prevent sedimentation of downstream portions of the affected streams, construction will be conducted in the dry through
the use of cofferdams and pump-arounds. Temporary erosion and sediment control measures placed in waters will be
removed and the original grade restored upon completion of the project. Banks affected by repair work will be re -seeded and
restored to stable bank conditions.
1 b. Specifically describe measures taken to avoid or minimize the proposed impacts through construction techniques.

NOTES:
1. CLASS OR MEDIAN SIZE OF RIPRAP AND LENGTH, WIDTH AND DEPTH OF APRON
TO BE DESIGNED BY THE ENGINEER.
2. REFER TO THE CHARLOTTE MECKLENBURG STORM WATER DESIGN MANUAL FOR
RIPRAP APRON DESIGN STANDARDS.
3. RIPRAP SHOULD EXTEND UP BOTH SIDES OF THE APRON AND AROUND THE END
OF THE PIPE OR CULVERT AT THE DISCHARGE OUTLET AT A MAXIMUM SLOPE OF
2:1 AND A HEIGHT NOT LESS THAN TWO THIRDS THE PIPE DIAMETER OR
CULVERT HEIGHT.
4. THERE SHALL BE NO OVERFLOW FROM THE END OF THE APRON TO THE
SURFACE OF THE RECEIVING CHANNEL. THE AREA TO BE PAVED OR RIPRAPPED
SHALL BE UNDERCUT SO THAT THE INVERT OF THE APRON SHALL BE AT THE
SAME GRADE (FLUSH) WITH THE SURFACE OF THE RECEIVING CHANNEL. THE
APRON SHALL HAVE A CUTOFF OR TOE WALL AT THE DOWNSTREAM END.
5. THE WIDTH OF THE END OF THE APRON SHALL BE EQUAL TO THE BOTTOM WIDTH
OF THE RECEIVING CHANNEL. MAXIMUM TAPER TO RECEIVING CHANNEL 5:1
6. ALL SUBGRADE FOR STRUCTURE TO BE COMPACTED TO 95% OR GREATER.
7. THE PLACING OF FILL, EITHER LOOSE OR COMPACTED IN THE RECEIVING
CHANNEL SHALL NOT BE ALLOWED.
8. NO BENDS OR CURVES IN THE HORIZONTAL ALIGNMENT OF THE APRON WILL BE
PERMITTED.
9. FILTER FABRIC SHALL BE INSTALLED ON COMPACTED SUBGRADE PRIOR TO
PLACEMENT OF RIP RAP.
10. ANY DISTURBED AREA FROM END OF APRON TO RECIEVING CHANNEL MUST BE
STABILIZED.
11. TO CONSTRUCT CHANNEL BED PLACE LARGER MATERIAL (5"-12") AS
SUBPAVEMENT. PLACE SMALLER MATERIAL (2"-6") AND NATURAL GOBBLE AND
#57 STONE AS PAVEMENT. MIX SAND, GRAVEL AND SOIL ON SITE. PLACE INTO
RIFFLE TO FORM A TIGHT SEAL AND PREVENT LOW FLOW FROM FLOWING
BETWEEN OR UNDER RIP RAP. MAX. BOULDER SIZE 30".
USE USDA NOMOGRAPH FROM NO SEDIMENT AND EROSION CONTROL MANUAL OR
CHARLOTTE MECKLENBURG STORM WATER DESIGN MANUAL FOR DESIGN DATA.

Jurisdictional Determination Request
I. REQUESTS FOR CORPS APPROVAL OF SURVEY PLAT
Prior to final production of a Plat, the Wilmington District recommends that the Land
Surveyor electronically submit a draft of a Survey Plat to the Corps project manager for
review.
Due to storage limitations of our administrative records, the Corps requires that all hard-
copy submittals include at least one original Plat (to scale) that is no larger than 11"x17'
(the use of match lines for larger tracts acceptable). Additional copies of a plat, including
those larger than 11"x17', may also be submitted for Corps signature as needed. The
Corps also accepts electronic submittals of plats, such as those transmitted as a Portable
Document Format (PDF) file. Upon verification, the Corps can electronically sign these
plats and return them via e-mail to the requestor.
(1) PLATS SUBMITTED FOR APPROVAL
❑ Must be sealed and signed by a licensed professional land surveyor
❑ Must be to scale (all maps must include both a graphic scale and a verbal scale)
❑ Must be legible
❑ Must include a North Arrow, Scale(s), Title, Property Information
❑ Must include a legible WoUS Delineation Table of distances and bearings/metes
and bounds/GPS coordinates of all surveyed delineation points
❑ Must clearly depict surveyed property or project boundaries
❑ Must clearly identify the known surveyed point(s) used as reference (e.g. property
corner, USGS monument)
❑ When wetlands are depicted:
• Must include acreage (or square footage) of wetland polygons
• Must identify each wetland polygon using an alphanumeric system
Version: December 2013 Page 8

Jurisdictional Determination Request
❑ When tributaries are depicted:
• Must include either a surveyed, approximate centerline of tributary with
approximate width of tributary OR surveyed Ordinary High Water Marks
(OHWM) of tributary
• Must identify each tributary using an alphanumeric system
• Must include linear footage of tributaries and calculated area (using approximate

1. The Corps of Engineers believes that there may be jurisdictional waters of the
United States on the subject site, and the permit applicant or other affected party
who requested this preliminary JD is hereby advised of his or her option to
request and obtain an approved jurisdictional determination (JD) for that site.
Nevertheless, the permit applicant or other person who requested this
preliminary JD has declined to exercise the option to obtain an approved JD in
this instance and at this time.
2. In any circumstance where a permit applicant obtains an individual permit, or
a Nationwide General Permit (NWP) or other general permit verification requiring
"pre -construction notification" (PCN), or requests verification for a non -reporting
NWP or other general permit, and the permit applicant has not requested an
approved JD for the activity, the permit applicant is hereby made aware of the
following: (1) the permit applicant has elected to seek a permit authorization
based on a preliminary JD, which does not make an official determination of
jurisdictional waters; (2) that the applicant has the option to request an approved
JD before accepting the terms and conditions of the permit authorization, and
that basing a permit authorization on an approved JD could possibly result in less
compensatory mitigation being required or different special conditions; (3) that
the applicant has the right to request an individual permit rather than accepting
the terms and conditions of the NWP or other general permit authorization; (4)
that the applicant can accept a permit authorization and thereby agree to comply
with all the terms and conditions of that permit, including whatever mitigation
requirements the Corps has determined to be necessary; (5) that undertaking
any activity in reliance upon the subject permit authorization without requesting
an approved JD constitutes the applicant's acceptance of the use of the
preliminary JD, but that either form of JD will be processed as soon as is
practicable; (6) accepting a permit authorization (e.g., signing a proffered
individual permit) or undertaking any activity in reliance on any form of Corps
permit authorization based on a preliminary JD constitutes agreement that all
wetlands and other water bodies on the site affected in any way by that activity
are jurisdictional waters of the United States, and precludes any challenge to
such jurisdiction in any administrative or judicial compliance or enforcement
action, or in any administrative appeal or in any Federal court; and (7) whether
the applicant elects to use either an approved JD or a preliminary JD, that JD
will be processed as soon as is practicable. Further, an approved JD, a proffered
individual permit (and all terms and conditions contained therein), or individual
permit denial can be administratively appealed pursuant to 33 C.F.R. Part 331,
and that in any administrative appeal, jurisdictional issues can be raised (see 33
C.F.R. 331.5(a)(2)). If, during that administrative appeal, it becomes necessary
to make an official determination whether CWA jurisdiction exists over a site, or
to provide an official delineation of jurisdictional waters on the site, the Corps will
provide an approved JD to accomplish that result, as soon as is practicable.

This preliminary JD finds that there "maybe" waters of the United States on the
subject project site, and identifies all aquatic features on the site that could be
affected by the proposed activity, based on the following information:
