Re: Pre -Construction Notification (NWP #39)
Huntersville Distribution Park — Phase 2 Modification
(SAW-2020-00447, DWR #21-0785)
Huntersville, Mecklenburg County, NC
Dear Mr. Perez and Mr. Wojoski:
On behalf of our client, MDH Partners LLC, Kimley-Horn (KH) is submitting the enclosed Section
404/401 Pre -construction notification (PCN) modification request for the above -referenced project for
your review pursuant to Nationwide Permit #39 and Individual 401 Water Quality Certification (WQC).
Authorization is requested to construct multiple warehouse distribution centers, associated parking
facilities, and stormwater infrastructure. The project is located in Huntersville, Mecklenburg County,
North Carolina. The center of the project area is located at 35.445033°,-80.834478°. The following
information is included as part of this PCN modification request:
• Revised Pre -Construction Notification Form
• Revised Permit Drawings
• Compensatory Mitigation
■ Mitigation Bank — Statement of Availability (SOA)
■ NC Stream Assessment Method (NCSAM) Forms
PROJECT BACKGROUND
The Huntersville Distribution Park is a proposed 65.5-acre two-phase industrial park located in
Huntersville, Mecklenburg County, NC. The project proposes the construction of four (4) distribution
facilities, on -site roadway, truck/trailer parking, employee parking, and stormwater facilities. Phase 1
which includes two (2) of the distribution facilities, has been completed. This request is applicable to
Phase 2 of the project only.
Design modifications are a result of comments from the City of Huntersville during plan review and are
a requirement from the City to obtain plan approvals. Conspan arch culverts were originally proposed
for the driveway crossings; however, due to the recent USACE guidance shift requiring 1:1
compensatory mitigation for arch span culverts as well as the significant increases in construction costs
since the original impacts were authorized, the applicant proposes installation of conventional RCP
culverts for the driveway crossings.

PROPOSED IMPACTS TO JURISDICTIONAL WATERS
Impacts to aquatic resources within Phase 2 are proposed to be conducted at two impact sites. The
following summarizes the proposed impacts:
Impact Site A
o Impact 3 — Permanent
■ 54 linear foot (LF), 48-inch reinforced concrete pipe (RCP) placed within
Stream 4. Per regional condition 9, the culvert will be installed below the
elevation of the streambed by one foot. To meet non -erosive design criteria,
10 LF of rip -rap outlet dissipation will be installed in a manner that the boulders
will be pushed or "keyed" into the channel bed so that the finished top elevation
of the rip -rap will not exceed that of the original stream bed to prevent
destabilization of the stream bed or bank upstream of the impact area and to
allow for aquatic life passage. Impact 1 results in 66 LF of permanent impacts
to S4.
o Impact 4 — Temporary
■ 30 LF of temporary impacts are necessary to install an impervious dike and
pumped diversion to perform the construction activity in dry conditions.
Impact Site B
o Impact 5 — Permanent
■ 70 LF, 60-inch reinforced concrete pipe (RCP) placed within Stream 4. Per
regional condition 9, the culvert will be installed below the elevation of the
streambed by one foot. To meet non -erosive design criteria, 10 LF of rip -rap
outlet dissipation will be installed in a manner that the boulders will be pushed
or "keyed" into the channel bed so that the finished top elevation of the rip -rap
will not exceed that of the original stream bed to prevent destabilization of the
stream bed or bank upstream of the impact area and to allow for aquatic life
passage. Impact 3 results in 87 LF of permanent impacts to S4.
o Impact 6 — Temporary
■ 30 LF of temporary impacts are necessary to install an impervious dike and
pumped diversion to perform the construction activity in dry conditions.
o Impact 7 — Temporary
■ 0.0007-acre of temporary impacts to Wetland 2 are necessary to perform the
construction activities.
o Impact 8 — Permanent
■ 0.0002-acre of permanent impacts to Wetland 3 results from grading
necessary to construct the headwall.
o Impact 9 — Temporary
■ 0.001-acre of temporary impacts to Wetland 3 are necessary to perform the
construction activities.
Phase 2 seeks authorization to permanently impact 153 LF/0.007-acre of non -wetland WOTUS
and 0.0002-acre of wetland WOTUS under NWP #39 and Individual 401 WQC for construction of
the warehouse distribution centers, associated parking facilities, and stormwater infrastructure.
60 LF/0.003-acre of temporary non -wetland WOTUS impacts are necessary to install pumped
diversion operations at the proposed culvert locations to allow for work in dry conditions.
0.0017-acre of temporary wetland WOTUS impacts are necessary to perform the construction
activities.

AVOIDANCE AND MINIMIZATION
Page 3
Avoidance and minimization efforts were implemented during development planning and design to the
greatest extent practicable in order to reduce the overall impacts on the aquatic environment while
staying within nationwide permit thresholds. The final plan demonstrates maximum avoidance and
minimization efforts by reducing the proposed stream impacts. The rationale to support avoidance and
minimization efforts includes the following:
• The original design included increased wetland impacts from grading and roadway crossings.
The roadways were moved to align with City of Huntersville requirements, and headwalls were
incorporated into the updated design to avoid further grading into the wetlands.
• The stream crossings at Impact Sites A and B have been designed to intersect Stream 4 at
nearly perpendicular angles to reduce the culvert lengths, minimize stream impacts, and
prevent bank erosion.
• Avoidance of the remaining 1.7698-acres of wetlands on -site.
• Temporary impacts to wetlands will be reseeded with a native wetland seed mix and returned to
pre -construction conditions.
COMPENSATORY MITIGATION
Prior to the modification, impacts associated with Phase 1 and Phase 2 did not exceed the mitigation
threshold for stream impacts. However, modifications associated with Phase 2, stream impacts now
exceed the minimum mitigation threshold; therefore, compensatory stream mitigation is proposed for
the entire project. Compensatory mitigation will be met by the purchase of stream credits through the
WLS Upper Rocky UMB — Upper Rocky bank. The following table summarizes the stream mitigation
credits:

D. Impact Justification and Mitigation
1. Avoidance and Minimization
1a. Specifically describe measures taken to avoid or minimize the proposed impacts in designing project.
Avoidance and minimization efforts were implemented during development planning and design to the greatest extent
practicable in order to reduce the overall impacts on the aquatic environment while staying within nationwide permit thresholds.
The final plan demonstrates maximum avoidance and minimization efforts by reducing the proposed stream impacts. The
rationale to support avoidance and minimization efforts includes the following:
• The original design included increased wetland impacts from grading and roadway crossings. The roadways were
moved to align with City of Huntersville requirements, and headwalls were incorporated into the updated design to
avoid further grading into the wetlands.
• The stream crossings at Impact Sites A and B have been designed to intersect Stream 4 at nearly perpendicular
angles to reduce the culvert lengths, minimize stream impacts, and prevent bank erosion.
• Avoidance of the remaining 1.7698-acres of wetlands on -site.
• Temporary impacts to wetlands will be reseeded with a native wetland seed mix and returned to pre -construction
conditions
1 b. Specifically describe measures taken to avoid or minimize the proposed impacts through construction techniques.
Stream crossings are sized and positioned to minimize impacts to the greatest extents practicable. Temporary erosion
control measures, including but not limited to skimmer basins and silt fence, will be implemented to minimize sediment laden
runoff from exiting the site. Temporary impacts have been minimized to the greatest extent practicable to meet the needs of
the project. Erosion control measures implemented during the construction of the site will be removed immediately following
the activities and any disturbance will be returned to pre -construction conditions.

Re Project: Huntersville Distribution Park
This document confirms that MDH Partners, LLC (Applicant) for the Huntersville Distribution Park
(Project) has expressed an interest to utilize 620.00 Stream Mitigation Credits from the Water & Land
Solutions, LLC sponsored Upper Rocky Umbrella Mitigation Bank, specifically 620.00 stream credits
from the Upper Rocky Site, in the Yadkin HUC 03040105. As the official Bank Sponsor, Water & Land
Solutions, LLC, attests to the fact that mitigation is available for reservation at this time.
These mitigation credits are not considered secured, and consequently are eligible to be used for alternate
purposes by the Bank Sponsor, until payment in full is received from the Applicant resulting in the
issuance of a Mitigation Credit Transfer Certificate by the bank acknowledging that the Applicant has
fully secured credits from the bank and the Banker has accepted full responsibility for the mitigation
obligation requiring the credits/units.
The Banker will issue the Mitigation Credit Transfer Certificate within three (3) days of receipt of the
purchase price. Banker shall provide to Applicant a copy of the Mitigation Credit Transfer Certificate and
a documented copy of the debit of credits from the Bank Official Credit Ledger(s), indicating the permit
number and the resource type secured by the applicant. A copy of the Mitigation Credit Transfer
Certificate, with an updated Official Credit Ledger will also be sent to regulatory agencies showing the
proper documentation.
If any questions need to be answered, please contact me at 239-322-7276.
