Subject: Application for Section 404 Nationwide Permits 13, 14, and 27 Reverification and Section 401
Water Quality Certification for the Proposed Caldwell Station Tributary Greenway, Mecklenburg County
(USACE Action ID SAW-2020-01659; NCDWR #21-0131)
Dear Mr. Perez:
On behalf of Mecklenburg County Asset and Facility Management, WSP USA has completed a Pre -Construction
Notification (PCN) application for the Caldwell Station Tributary Greenway project to request reverification of
Nationwide Permits 13, 14 and 27 from the US Army Corps of Engineers (USACE) and the associated 401 Water
Quality Certifications (WQC) from the North Carolina Division of Water Resources (NCDWR).
The USACE issued an NWP verification for the project on August 18, 2021 and the NCDWR issued a 401 Water
Quality Certification on December 8, 2021. The project was under contract to commence prior to the NWP
verification expiration date of March 18, 2022, however, the previously authorized work in waters of the U.S. will
not be completed within the 12-month extension period ending on March 18, 2023. There have been no changes to
the project, which proposes to construct a new greenway trail, approximately 1.0 mile in length, that will connect
the existing Caldwell Station Creek Greenway to the new Northern Regional Recreation Center. The greenway
runs parallel to the Caldwell Station Tributary Creek, partially within a Duke Energy easement, and is designed to
include two neighborhood connections, one at Caldwell Depot Road and one at Caldwell Track Drive, as well as a
connection to an existing commercial development to the north. The proposed project will include a paved ten -foot
wide greenway with two -foot shoulders, plantings, storm water controls, and culverts that will impact streams.
Reinforced concrete box culverts will be installed at two stream crossings with instream work proposed at either
end of the culverts to enhance the stream channel by increasing channel bed and bank stability and improving
bedform diversity. A third stream will be piped and the stream channel filled as part of the greenway project. Total
proposed permanent stream impacts include 106 linear feet of fill impact, 72 linear feet of culvert fill impact, 129
linear feet of stream enhancement, and 8 linear of stream bank stabilization. Total proposed temporary stream
impacts include 73 linear feet. No wetland impacts are proposed. The proposed impacts to waters of the U.S. have
not changed from the previous NWP and WQC approvals. The attached permit drawings are unchanged from the
previous approvals.
The County satisfied the mitigate obligation for 178 linear feet of stream impacts through purchase of 267 credits
from the City of Charlotte Umbrella Wetland and Stream Mitigation Bank. Referenced the attached Compensatory
Mitigation Responsibility Transfer Form.

Instructions to Permittee: The Permittee must provide a copy of this form to the Mitigation Sponsor, either an approved
Mitigation Bank or the North Carolina Division of Mitigation Services (NCDMS), who will then sign the form to verify the
transfer of the mitigation responsibility. Once the Sponsor has signed this form, it is the Permittee's responsibility to ensure
that Wilmington District Project Manager identified on page two is in receipt of a signed copy of this form before conducting
authorized impacts, unless otherwise specified below. If more than one Mitigation Sponsor will be used to provide the
mitigation associated with the permit, or if the impacts and/or the mitigation will occur in more than one 8-digit Hydrologic
Unit Code (HUC), multiple forms will be attached to the permit, and the separate forms for each Sponsor and/or HUC must
be provided to the appropriate Mitigation Sponsors.
Instructions to Sponsor: The Sponsor verifies that the mitigation requirements (credits) shown below have been released
and are available at the identified site. By signing below, the Sponsor is accepting full responsibility for the identified
mitigation, regardless of whether they have received payment from the Permittee. Once the form is signed, the Sponsor
must update the bank ledger and provide a copy of the signed form and the updated ledger to the Permittee, the Project
Manager who issued the permit, the Bank Project Manager, and the District Mitigation Office (see contact information on

Date of Signature
Conditions for Transfer of Compensatory Mitigation Credit:
• Once this document has been signed by the Mitigation Sponsor and the District is in receipt of the signed form, the
Permittee is no longer responsible for providing the mitigation identified in this form, though the Permittee remains
responsible for any other mitigation requirements stated in the permit conditions.
• Construction within jurisdictional areas authorized by the permit identified on page one of this form can begin only after
the District is in receipt of a copy of this document signed by the Sponsor, confirming that the Sponsor has accepted
responsibility for providing the mitigation requirements listed herein. When NCDMS provides mitigation for authorized
impacts conducted by the North Carolina Department of Transportation (NCDOT), construction within jurisdictional areas
may proceed upon permit issuance; however, a copy of this form signed by NCDMS must be provided to the District
within 30 days of permit issuance. NCDOT remains fully responsible for the mitigation until the District has received this
form, confirming that the Sponsor has accepted responsibility for providing the mitigation requirements listed herein.
• Signed copies of this document must be retained by the Permittee, Mitigation Sponsor, and in the USACE administrative
records for both the permit and the Bank/ILF Instrument. It is the Permittee's responsibility to ensure that the District
Project Manager (address below) is provided with a signed copy of this form.
• If changes are proposed to the type, amount, or location of mitigation after this form has been signed and returned to
the District, the Sponsor must obtain case -by -case approval from the District Project Manager and/or North Carolina
Interagency Review Team (NCIRT). If approved, higher mitigation ratios may be applied, as per current District guidance
and a new version of this form must be completed and included in the District administrative records for both the permit
and the Bank/ILF Instrument.
Comments/Additional Conditions: A letter from City of Charlotte Umbrella Stream and Wetland Mitigation Bank,
confirming they are willing and able to accept the applicant's compensatory mitigation responsibility, dated 8/11/2021 was
included with the preconstruction notification.
This form is not valid unless signed below by the District Project Manager and by the Mitigation Sponsor on Page 1. Once
signed, the Sponsor should provide copies of this form along with an updated bank ledger to: 1) the Permittee, 2) the
District Project Manager at the address below, 3) the Bank Manager listed in RIBITS, and 4) the Wilmington District
Mitigation Office, 3331 Heritage Trade Drive, Suite 105, Wake Forest, NC 27587 (or by email to [e-mail] V.mil).

Longitude:-80.855661
Location description: The review area is located north of Train Station Road. Multiple PINs. Reference review area description
shown in Jurisdictional Determination Request entitled "Figure 1, Site Location Map" and Dated September 2020.
Indicate Which of the Following Apply:
A. Preliminary Determination
® There appear to be waters, including wetlands on the above described project area/property, that may be subject to Section 404
of the Clean Water Act (CWA)(33 USC § 1344) and/or Section 10 of the Rivers and Harbors Act (RHA) (33 USC § 403). The
waters, including wetlands have been delineated, and the delineation has been verified by the Corps to be sufficiently accurate
and reliable. The approximate boundaries of these waters are shown on the enclosed delineation map dated September 2020.
Therefore this preliminary jurisdiction determination may be used in the permit evaluation process, including determining
compensatory mitigation. For purposes of computation of impacts, compensatory mitigation requirements, and other resource
protection measures, a permit decision made on the basis of a preliminary JD will treat all waters and wetlands that would be
affected in any way by the permitted activity on the site as if they are jurisdictional waters of the U.S. This preliminary
determination is not an appealable action under the Regulatory Program Administrative Appeal Process (Reference 33 CFR Part
331). However, you may request an approved JD, which is an appealable action, by contacting the Corps district for further
instruction.
❑ There appear to be waters, including wetlands on the above described project area/property, that may be subject to Section 404
of the Clean Water Act (CWA)(33 USC § 1344) and/or Section 10 of the Rivers and Harbors Act (RHA) (33 USC § 403).
However, since the waters, including wetlands have not been properly delineated, this preliminary jurisdiction determination
may not be used in the permit evaluation process. Without a verified wetland delineation, this preliminary determination is
merely an effective presumption of CWA/RHA jurisdiction over all of the waters, including wetlands at the project area, which
is not sufficiently accurate and reliable to support an enforceable permit decision. We recommend that you have the waters,
including wetlands on your project area/property delineated. As the Corps may not be able to accomplish this wetland
delineation in a timely manner, you may wish to obtain a consultant to conduct a delineation that can be verified by the Corps.
B. Approved Determination
❑ There are Navigable Waters of the United States within the above described project area/property subject to the permit
requirements of Section 10 of the Rivers and Harbors Act (RHA) (33 USC § 403) and Section 404 of the Clean Water Act
(CWA)(33 USC § 1344). Unless there is a change in law or our published regulations, this determination may be relied upon for
a period not to exceed five years from the date of this notification.
❑ There are waters, including wetlandson the above described project area/property subject to the permit requirements of Section
404 of the Clean Water Act (CWA) (33 USC § 1344). Unless there is a change in the law or our published regulations, this
determination may be relied upon for a period not to exceed five years from the date of this notification.
❑ We recommend you have the waters, including wetlands on your project area/property delineated. As the Corps may not be
able to accomplish this wetland delineation in a timely manner, you may wish to obtain a consultant to conduct a delineation that
can be verified by the Corps.
❑ The waters, including wetlands on your project area/property have been delineated and the delineation has been verified by
the Corps. The approximate boundaries of these waters are shown on the enclosed delineation map dated DATE. We strongly

SAW-2020-01659
suggest you have this delineation surveyed. Upon completion, this survey should be reviewed and verified by the Corps. Once
verified, this survey will provide an accurate depiction of all areas subject to CWA jurisdiction on your property which, provided
there is no change in the law or our published regulations, may be relied upon for a period not to exceed five years.
❑ The waters, including wetlands have been delineated and surveyed and are accurately depicted on the plat signed by the
Corps Regulatory Official identified below onDATE. Unless there is a change in the law or our published regulations, this
determination may be relied upon for a period not to exceed five years from the date of this notification.
❑ There are no waters of the U.S., to include wetlands, present on the above described project area/property which are subject to the
permit requirements of Section 404 of the Clean Water Act (33 USC 1344). Unless there is a change in the law or our published
regulations, this determination may be relied upon for a period not to exceed five years from the date of this notification.
❑ The property is located in one of the 20 Coastal Counties subject to regulation under the Coastal Area Management Act (CAMA).
You should contact the Division of Coastal Management in Morehead City, NC, at [phone] to determine their
requirements.
Placement of dredged or fill material within waters of the US, including wetlands, without a Department of the Army permit may
constitute a violation of Section 301 of the Clean Water Act (33 USC § 1311). Placement of dredged or fill material, construction or
placement of structures, or work within navigable waters of the United States without a Department of the Army permit may
constitute a violation of Sections 9 and/or 10 of the Rivers and Harbors Act (33 USC § 401 and/or 403). If you have any questions
regarding this determination and/or the Corps regulatory program, please contact Bryan Roden -Reynolds at 704-510-1440 or
brvan.roden-reynolds(&u sace.army.mil.
C. Basis For Determination: Basis For Determination: See the preliminary jurisdictional determination
form dated 09/25/2020.
D. Remarks: None.
E. Attention USDA Program Participants
This delineation/determmation has been conducted to identify the limits of Corps' Clean Water Act jurisdiction for the particular site
identified in this request. The delineation/determination may not be valid for the wetland conservation provisions of the Food Security
Act of 1985. If you or your tenant are USDA Program participants, or anticipate participation in USDA programs, you should request
a certified wetland determination from the local office of the Natural Resources Conservation Service, prior to starting work.
F. Appeals Information (This information applies only to approved jurisdictional determinations as indicated in B.
above)

1. The Corps of Engineers believes that there may be jurisdictional aquatic resources in the
review area, and the requestor of this PJD is hereby advised of his or her option to request
and obtain an approved JD (AJD) for that review area based on an informed decision after
having discussed the various types of JDs and their characteristics and circumstances when
they may be appropriate.
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 AID for the activity, the permit
applicant is hereby made aware that: (1) the permit applicant has elected to seek a permit

authorization based on a PJD, which does not make an official determination of
jurisdictional aquatic resources; (2) the applicant has the option to request an AJD before
accepting the terms and conditions of the permit authorization, and that basing a permit
authorization on an AJD could possibly result in less compensatory mitigation being
required or different special conditions; (3) 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) 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)
undertaking any activity in reliance upon the subject permit authorization without
requesting an AJD constitutes the applicant's acceptance of the use of the PJD; (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 PJD
constitutes agreement that all aquatic resources in the review area affected in any way by
that activity will be treated as jurisdictional, and waives 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 AJD or
a PJD, the JD will be processed as soon as practicable. Further, an AJD, 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. If, during an
administrative appeal, it becomes appropriate to make an official determination whether
geographic jurisdiction exists over aquatic resources in the review area, or to provide an
official delineation of jurisdictional aquatic resources in the review area, the Corps will
provide an AJD to accomplish that result, as soon as is practicable. This PJD finds that
there "may be" waters of the U.S. and/or that there "may be" navigable waters of the U.S.
on the subject review area, and identifies all aquatic features in the review area that could
be affected by the proposed activity, based on the following information:

SUBJECT: Caldwell Station Tributary Greenway (#20210131) - Response to Comments Received on
September 29t", 2021
Please find below a response to the comments we received regarding the permit application for construction of
the Caldwell Station Greenway (ID #20210131). Do not hesitate to reach out if you need any additional
information.
1. Clarify if the culvert is a double -barrel or a single -barrel culvert.
a. There are two reinforced concrete box culvert crossings, at two separate locations, included in
this project. Both crossings are 12'(w) x 9'(h) with a single rectangular barrel.
Provide information for low -flow and storm -flow conditions through the proposed culverts.
a. Low -flow calculations have been computed based on the low -flow channel dimensions which will
be maintained through installation of sills/baffles. A sketch of these measures and the associated
channel calculations are included below as Attachment A.
b. Design storm discharges have been confirmed using appropriate USGS regression equations,
and the culvert performance has been analyzed in HY-8. The culverts were analyzed to reflect
an embedment depth of 12" as well as an additional 9"-12" of blockage for low -flow channel
benches. As such, in the HY-8 models a representative embedment depth of 2' was utilized, to
ensure a conservative capacity analysis. Calculations for storm flow conveyance are included as
Attachment B.
3. Confirm base flow width and reflect this width in the low -flow channel design.
a. Based on site observations, a low flow channel base width of 4' has been selected for the culvert
at 25+95 (701-702). A base width of 3' has been selected for the culvert at 33+88 (901-902).
4. Ensure a good blend of materials (riprap, #57 stone, gravel, screenings, and sand/clay) are incorporated
into the design for the channel bed.
a. A revised bed mixture has been included in the plans for the channel (25% Class A riprap, 25%
Class B riprap, 25% #57 stone, and 25% native materials). Permit drawing Figure 7 (constructed
channel detail), has been revised to change the note regarding mixture of stream bed material. In
addition, Figure 5A (plan view of Impact Sites S1 — S5) and Figure 6A (plan view of Impact Sites
S6 to S8) have been revised to further clarify the design details. These revised figures are
included in Attachment C. Note, there have been no changes to impact location, length or area.
b. The low flow channel in the culvert (Attachment A) will also incorporate a mix involving larger
stone. However, that stone is not intended to be exposed. Native bedload will be retained in the
culvert by the proposed sills. The stone mixture will provide bed diversity and assist with rate of
refill after larger storm events if the native sand is washed out of the culvert.
