UT to Stony Creek
Onsite Stream Relocation Plan for
Widening of Eastern Ave/Sunset Ave and New Interchange at I-95
Nash County, North Carolina

T.I.P. Number U-5026 / R-5720

August 19, 2020

1.0 BASELINE INFORMATION/EXISTING CONDITIONS
The project is located within USGS Hydrologic Cataloging Unit 03020101 and NC Division of
Water Quality (NCDWQ) sub-basin 03-03-02 of the Tar Pamlico River Basin. NCDOT is
providing this onsite stream relocation plan to offset jurisdictional stream impacts associated
with Transportation Improvement Program (TIP) U-5026 and R-5720. The project would serve
to avoid and minimize impacts and to reduce the mitigation required for the UT to Stony Creek
that will be relocated to the north of its current location. The site is located parallel to
Eastern/Sunset Avenue and is bisected by I-95 in Nash County to the east of Nashville and west
of Rocky Mount, on land that the North Carolina Department of Transportation (NCDOT) will
acquire as permanent drainage easement. Land use within the watershed is primarily
commercial/industrial development, forested areas, and residential. The existing stream length,
drainage area, and jurisdictional status are summarized in Table 1.

Stony Creek has been assigned Stream Index Number 28-68 (NCDWR 2020) and is designated a
warm water stream with a classification of C, NSW. Class C waters are protected for secondary
recreation, fishing, and aquatic life. NSW or Nutrient Sensitive Waters is a supplemental
classification intended for waters needing additional nutrient management. The stream is within
the Tar Pamlico River Basin and is subject to riparian buffer rules.
The UT to Stony Creek is approximately 4 feet wide and 4 inches deep and runs for
approximately 740 feet easterly along the toe of slope of Sunset Avenue. The channel through
this section has mainly herbaceous buffer due to maintenance within adjacent utility easements.
The channel passes under I-95 in a 36 inch RCP parallel and then continues parallel to Sunset
Avenue for another 452 feet to its confluence with Stony Creek. The buffer through this section
consists of herbaceous vegetation with scattered woody species. The bed and banks of the
channel are bare in locations and shows signs of erosion with little vegetation on the banks. The
Page 2 of 3

substrate consists mainly of sand, silt, and gravel. Some macroinvertebrates were found in
previous natural resource studies, however, no fish, crayfish, amphibians, or mussels were noted.
NC SAM Field Assessment Forms were completed for the channel in three distinct sections (east
of I-95, west of I-95A, and west of I-95B) based on the existing condition of the stream and its
surroundings. The section west of I-95 was broken into two sections due to the difference in the
riparian buffer. All three sections scored low overall but for varying reasons. See the attached
SAM forms and photos of the stream.
The west of I-95 Section A stream reach had a number of areas which scored lower than the
other reaches. This section has been heavily impacted by the continued maintenance within the
utility easement. The channel has been straightened and there is no tree canopy, no woody
riparian buffer, and very little habitat throughout this section. This reach is approximately 240
linear feet. See Photos 1 to 4 attached.

The west of I-95 Section B reach begins where there is a riparian buffer. This reach also scored
low overall but appears to be in better condition than the adjacent section due to the riparian
buffer and canopy, stream geomorphology, and habitat; however, it exhibits intermittent flow
and sedimentation. This reach is approximately 530 linear feet. See Photos 5 to 15 attached.
The east of I-95 section begins at the outlet of the pipe and ends after the stream crosses the
utility easement. This section of stream has been significantly altered by straightening in the
past. The reach exhibits signs of being intermittent in locations, has areas of bare banks, low
stream geomorphology, sedimentation, and severe erosion at the utility easement. This reach is
approximately 470 linear feet. See Photos 16 to 34 attached.
*Please note the photos were taken the day following Hurricane Isaias landfall in eastern North
Carolina. The flow is minimal in the photos and appears more as ponding than actual stream
flow with some sections having no flow at all. Also, note the amount of sediment in the channel
as well as areas of erosion.
2.0 PROPOSED CONDITIONS
The U-5026/R-5720 Design Build project requires relocation of Stream SF due to fill necessary
for the interchange with I-95. The design of a partial cloverleaf at this location allows the stream
to be relocated to the north. The relocation of the channel is considered to be a better solution
than piping the channel as it will allow the channel to remain daylighted. The potential uplift to
stream function is provided by building a stable channel with 3:1 side slopes that can maintain
vegetation on the banks and also reduce sedimentation and provide better aquatic habitat.
The goal of the project is to provide ecological uplift to the existing channel while relocating
1192 linear feet of the UT to Stony Creek. The goals would be accomplished by providing a 990
feet long stable channel for the UT to Stony Creek north of its current location as well as
Page 3 of 3

replanting the stream bank and buffer as available within NCDOT owned property. This will
contribute to in-stream and stream side habitat, stabilization of the banks, and thermoregulation.
The relocated channel will be constructed with 5 foot wide base with 3:1 side slopes that tie to
natural ground, mimicking appropriate channel dimensions for a <1 sq mile watershed. The
banks will be stabilized with coir fiber matting. Following the successful completion of site
grading and stabilization, the vegetation plan for the site will include the planting of live stakes
along the banks of the channel and bare-root trees in riparian buffer areas adjacent to the UT to
Stony Creek where feasible and not in conflict with nearby utility easements. Tree species
commonly found in Bottomland Hardwood forests will be planted across the site that include a
mixture of no less than six native species adapted to site conditions, such as black willow (Salix
nigra), silky dogwood (Cornus amomum), river birch (Betula nigra), sycamore (Platanus
occidentalis), overcup oak (Quercus lyrata), and swamp chestnut oak (Quercus michauxii). Live
stakes of black willow and silky dogwood will be used along the banks of the relocated will be
used along the UT to Stony Creek.
Native grass seeding and mulching will be applied on all disturbed areas within the stream
relocation area for stabilization purposes according to guidance and standard procedures of
NCDOT’s Roadside Environmental Unit.
The relocation and reforestation would be constructed at the same time of the U-5026 and R-
5720 Design Build Project. Utility plans have been assessed and accounted for during the
development of the stream relocation plan. These areas are illustrated on the planting plan as
areas void of Type II streambank reforestation.
3.0 MONITORING REQUIREMENTS AND SUCCESS CRITERIA
The site will be monitored annually for five years using photo documentation and visual
inspection. Monitoring will be performed each year with visual inspection for channel stability
and plant survival. Specific problem areas and proposed/required remedial action will be
identified if necessary. Physical measurements of channel stability/morphology will not be
performed. A brief summary will be provided to the permitting agencies annually on the results
of the monitoring.
