Re: Pre-Construction Notification (NWP 3 & 13) Application
Stream Bank Repairs on Irwin Creek
Charlotte, Mecklenburg County, NC
Dear Mr. Shaeffer and Ms. Higgins:
On behalf of our client, Charlotte Water, Kimley-Horn is submitting the enclosed joint Section
404/401 Preconstruction Notification Application for the above referenced project for your review
pursuant to Nationwide Permits #3 and #13 and General 401 Water Quality Certification numbers
4132 and 4134. This application is to conduct stream stabilization/infrastructure maintenance
activities for the purposes of protecting two sanitary sewer manholes beside Irwin Creek, and
reducing erosion, stabilizing the bed and banks, and protecting an exposed 27-inch reinforced
concrete sanitary sewer pipe (RCP) on one Unnamed Tributary to Irwin Creek located at
approximately 35.267078°N, -80.831998°W. The following information is included as part of this
application submittal:

The project is located southeast of the intersection of I-85 and Statesville Avenue off Northerly Road
in the City of Charlotte, Mecklenburg County, North Carolina. Existing land use in the vicinity of the
project is a mix of Industrial, Single-Family Residential, and Forested.
The Pre-Construction Notification (NWP 3 & 13) application presents site conditions evaluated by
Kimley-Horn staff (Chris Tinklenberg, PWS) on July 23, 2015. The stream delineation was
performed by utilizing survey prepared by a licensed surveyor (verified by Kimley-Horn).
The proposed project consists of two components: 1) the protection of two sanitary sewer manholes
along Irwin Creek (S1 – Impacts 1 & 2), and 2) stabilizing the beds and banks, reducing erosion, and
protection of a 27” RCP in the channel of an Unnamed Tributary to Irwin Creek (S2 – Impacts 3 &
4). Instabilities and erosion have exposed the sanitary sewer structures in both streams, increasing the
likelihood of failure. To protect the manholes, Component 1 of the project is composed of two
separate sections of 40 LF (Impact 1) and 60 LF (Impact 2) of sheet piling in Irwin Creek (S1). Sheet
piling is used instead of conventional bank stabilization because the site is a documented brownfield.
Charlotte Water seeks to disturb as little soil as possible to prevent the exposure of any unknown
contaminants. The sheet pilings will act as temporary stabilization to protect Charlotte Water’s
infrastructure until a planned future greenway and stream restoration project are implemented.
Component 2 of the project consists of 72 linear feet of permanent-no net loss impacts to non-wetland
waters of the US. These impacts are necessary to implement natural channel design techniques
(Impact 3) within a short, perennial Unnamed Tributary to Irwin Creek (S2). The proposed boulder
and rip-rap step-pool will create grade control, reduce erosion, and protect the existing 27” RCP
sanitary sewer pipe. Stabilizing the Unnamed Tributary will also require 10 LF of temporary impacts
to install impervious dikes and a pumped diversion (Impact 4) to allow for work in dry conditions. It
is anticipated that a back-hoe and/or mini excavator will be used to shape the channels and construct
the step-pool structures.
Please feel free to contact Chris Tinklenberg at (704) 409-1802 if you have any questions, or if
additional information is necessary.
Sincerely,
KIMLEY-HORN AND ASSOCIATES, INC.

Impact Summary (if applicable): 100 LF of permanent-no net loss impacts to non-wetland WoUS are necessary to
install sheet pilings along the bank of Irwin Creek near two sanitary sewer manholes in order to prevent further
streambank erosion near these structures. Additionally, the project will result in 72 LF of permanent-no net loss impacts
to non-wetland WoUS by implementing natural channel design techniques to construct a boulder and riprap step-pool in
order to create grade control, reduce erosion and protect infrastructure. 10 LF of temporary impacts are necessary in order
to perform construction activities necessary to work in dry conditions.

1a. Specifically describe measures taken to avoid or minimize the proposed impacts in designing project.
All impacts are associated with stream stabilization/maintenance activities and will follow specific stream stabilization
protocols.
1b. Specifically describe measures taken to avoid or minimize the proposed impacts through construction techniques.
Several of the measures that will be implemented in order to minimize impacts include the utilization of a pump-around to
facilitate work in the dry, the use of temporary erosion control matting and planting of native vegetation for stabilization. All
sediment and erosion control and de-watering measures will be removed upon completion of construction and the temporary
areas of disturbance will be stabilized and restored to pre-construction contours.

RE: Stream Bank Repairs on Irwin Creek; 015474025_8
Dear Chris Tinklenberg:
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, 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 and is
included for reference. Tables of natural areas and conservation/managed area within a one-mile radius of the
project area, if any, are also included in this report.
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 (DNP), Registered Heritage Area (RHA), Clean Water Management Trust Fund
(CWMTF) 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.butler@ncdcr.gov or 919.707.8603.
Sincerely,
NC Natural Heritage Program
