West Branch Rocky River Rehabilitation and Water Quality Improvements
(SAW#-201902441)
Davidson, Mecklenburg County, NC
Dear Mr. Roden -Reynolds and Mr. Wojoski:
On behalf of our client, Charlotte -Mecklenburg (County) Stormwater Services, Kimley-Horn and
Associates, Inc. (KH) is submitting the reauthorization to the joint Section 404/401 Pre -Construction
Notification for the above referenced project for your review pursuant to Nationwide Permit #27 and
General 401 Water Quality Certification number 4134. This application is to request reauthorization to
conduct stream bank stabilization and in -stream enhancement activities for the purposes of improving
water quality, bank stabilization, and aquatic habitat. Based on comments from the local community
and in an effort to preserve more tree canopy, the stream restoration design along West Branch
Rocky River (WBRR) has been modified slightly (reduced meander) resulting in a reduction of 87 LF
of restored stream length; however, the project's overall goals and objectives remain unchanged. The
center of the project area is located at 35.491806°N,-80.805119°W. The following information is
included as part of this reauthorization submittal:
• Project Summary Sheet
• Pre -Construction Notification Form
• Permit Figures
■ Figure 5 — Proposed Conditions
• Permit Drawings for West Branch Rocky River Stream Restoration
PROJECT DESCRIPTION
The County proposes to perform stream restoration and enhancement activities along the WBRR
within the project corridor. The proposed restoration activities seek to reduce bank erosion, improve
channel dimension, and stabilize bank areas in close proximity to the existing multi -use path.
Stabilization includes bank grading to a stable slope, rock toe protection, and buffer revegetation. The
project corridor begins adjacent to WBRR, from Grey Road to Fisher Farm Park. The corridor also
includes an unnamed tributary of WBRR which flows from the west, from Ashby Road to the
confluence of WBRR at Fischer Farm Park. Construction activities associated with the UT to WBRR

Kimley>Morn Paget
are complete; however, the remaining construction activities along WBRR would not be completed by
the expiration date of the existing authorization, therefore, reauthorization is requested.
STREAM REHABILITATION APPROACH
Goals and Objectives:
The goal of the stream and buffer rehabilitation is to improve the hydraulic and geomorphic function of
WBRR to create a foundation for potential improvements of water quality and aquatic/terrestrial
habitat of the site's streams and floodplain through the following objectives:
• Improve the hydraulic geometry to have a low -flow channel, inner berm, and bankfull channel
more representative of reference conditions with less active bank erosion.
• Create bank angles and hydraulic geometry that allow vegetation and root mass to extend
from the water's edge up to the top of the channel banks.
• Improve the stem and root density and species diversity of the riparian buffer immediately
adjacent to WBRR.
• Reduce the BEHI scores along the reach from high, very high, or extreme to low.
• Reduce incision, erosive velocities, and high -shear stress by adding a floodplain bench
(where constraints allow).
• Create local slope and bed -depth variability (i.e. habitat transitions) by adding instream
structures like rock and log vanes, J-hook vanes, boulder and log riffles, and toe wood.
• Increase dissolved oxygen concentrations through in -stream structures and the turbulence
they produce in pools.
• Stabilize stream banks using bioengineering and/or specific natural channel design
techniques for each reach based on constraints and opportunities.
• Reduce bank source sediment by implementing bank stabilization and natural channel design
techniques. We will retrofit some off -site sediment sources, such as point source outlets and
ditches, with pocket wetlands, level spreaders, or RSCs.
• Introduce woody structures such as log vanes, log sills, and toe wood by adding wood and
detritus into the system.
• Control the invasive exotics by pretreatment, removal during construction, and implementing
an invasive species control plan.
• Protect infrastructure
• Implement best management practice (BMP)/stormwater control measures (SCM)
opportunities to stabilize stormwater outfalls.
Improvements in the higher functions of water quality and biology may not be fully achievable given
the upstream urban land use and point and non -point discharges that outfall into WBRR. However,
improving the underlying stream hydraulic and geomorphic functions of the channel would better
support these improvements in higher functions if watershed conditions allow.
Based on the objectives above, a specific detailed stream rehabilitation plan was completed. Each
reach has a tailored approach/plan that takes advantage of the opportunities to improve geomorphic
and hydraulic functions given the constraints.
To meet the goals and objectives described above, stream enhancement and restoration activities will
be conducted, resulting in 18,527 linear feet of permanent, no -net loss of potential non -wetland
WoUS. The project will result in a total net gain of 312 If to waters of the US from implementing
natural channel design techniques to return the channels to their natural bed and stabilizing erosive

Kimley>»Horn
banks to WBRR and its tributaries. The project will result in 0.025 acres of temporary impacts to
potential wetland WoUS from the temporary haul road to allow construction access necessary to
conduct the stream restoration project.
AVOIDANCE AND MINIMIZATION
All impacts are associated with stream restoration activities and will follow specific restoration
protocols. The project will result in a net gain of 312 If to waters of the US from implementing natural
channel design techniques to return the channels to their natural bed and stabilizing erosive banks to
WBRR and its tributaries. Several of the measures that will be implemented in order to minimize
impacts include the utilization of a pumped diversion to facilitate work in the dry, the use of temporary
erosion control matting and planting of native vegetation for stabilization. The pumped diversion will
be utilized for working in the dry to the greatest extent practicable; however, some construction
activities may require the contractor to temporarily work in the wet. Please provide special
conditions authorizing the contractor to work in the wet where a pumped diversion is not
feasible. 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. Temporary bridge crossings will be utilized along haul roads in order to
avoid additional temporary stream impacts. Mud mats will be temporarily placed in wetland areas to
allow crossing for construction equipment in order to minimize temporary wetland impacts.
Please feel free to contact me at [phone] if you have any questions, or if additional
information is necessary.

application:
PROJECT DESCRIPTION
The County proposes to perform stream restoration and enhancement activities along the WBRR within the project
corridor. The proposed restoration activities seek to reduce bank erosion, improve channel dimension, and stabilize
bank areas in close proximity to the existing multi -use path. Stabilization includes bank grading to a stable slope, rock
toe protection, and buffer revegetation. The project corridor begins adjacent to WBRR, from Grey Road to Fisher Farm
Park. The corridor also includes an unnamed tributary of WBRR which flows from the west, from Ashby Road to the
confluence of WBRR at Fischer Farm Park. Construction activities associated with the UT to WBRR are complete;
however, the remaining construction activities along WBRR would not be completed by the expiration date of the
existing authorization, therefore, reauthorization is requested.
SITE DESCRIPTION
The project corridor is located in the piedmont region of North Carolina. Topography is moderate within the study
corridor and roughly ranges from 650 to 750 feet in elevation (Figure 2; National Geodetic Vertical Datum 1929).
The project is located in the Pee Dee River Basin. A field review by Kimley-Horn environmental scientists was
conducted on January 23, 2018, February 6, 2019, and July 30, 2019. WBRR, a potential non -wetland water of the US
(WoUS), sixteen (16) additional unnamed tributaries (potential non -wetland WoUS), and five (5) potential wetland
WoUS are located within the project study corridor (Figures 4a-4f). WBRR discharges into Rocky River approximately
2.2 miles southeast of the project study corridor, which subsequently discharges into the Pee Dee River an additional
45 miles to the south.
WBRR is rated by the North Carolina Department of Environment and Natural Resources (NCDENR) Division of Water
Resources (DWR) as Class C with the following DWR Stream Index # 13-17-3. Class C waters are protected for
primary recreation, fishing, wildlife, fish consumption, aquatic habitat and agricultural uses. Currently, WBRR is not
classified as 303d listed (i.e. "impaired"). The project study corridor does not lie within a Water Supply Watershed and
there are no Outstanding Resource Waters or High Quality Waters within the study corridor.
3b. List the total estimated acreage of all existing wetlands on the property:
0.16 Acres
3c. List the total estimated linear feet of all existing streams (intermittent and perennial) on the property:
The total length of all on -site streams is approximately 18,698 linear feet.
3d. Explain the purpose of the proposed project:
The purpose of the project to conduct bank stabilization and in -stream enhancement activities on West Branch Rocky
River as well as five Unnamed Tributaries to West Branch Rocky River in order to improve water quality, aquatic habitat
and bank stabilization.

D. Impact Justification and Mitigation
1. Avoidance and Minimization
1a. Specifically describe measures taken to avoid or minimize the proposed impacts in designing project.
All impacts are associated with stream restoration activities and will follow specific restoration protocols. The project will result
in a net gain of 312 If to waters of the US from implementing natural channel design techniques to return the channels to their
natural bed and stabilizing erosive banks to WBRR and its tributaries.
1 b. 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 pumped diversion to
facilitate work in the dry, the use of temporary erosion control matting and planting of native vegetation for stabilization. The
pumped diversion will be utilized for working in the dry to the greatest extents practicable; however, some construction
activities may require the contractor to temporarily work in the wet. Please provide special conditions authorizing the
contractor to work in the wet where a pumped diversion is not feasible. 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. Temporary bridge crossings will be utilized along haul roads in order to avoid
additional temporary stream impacts. Mud mats will be temporarily placed in wetland areas to allow crossing for construction
equipment in order to minimize temporary wetland impacts.
