Road: SR 1512 (Olive Branch Road)
County: Person
River Basin: Roanoke
Stream Name: Big Bluewing Creek
Lat, Long: N36.48195, W78.83810
HUC: 030101040607
NCDENR-DWQ Index Number, Stream Classification: 22-58-16; C
Existing structure: Two lines of 72" diameter corrugated metal pipe 60ft long with a
concrete headwall.
Proposed structure: Replace with two lines of 103" x 71" corrugated metal pipe arch. This
new structure is 60ft long. The new pipes will be buried 1ft below the stream bed. Rip rap
will be installed underlined with geotextile for long term stability surrounding the tie-ins to
existing banks.
Riparian Buffers: Equipment used and work performed will be from the existing
transportation facility. Foot traffic access for installation of temporary dewatering measures
will be limited just upstream and downstream of the pipe replacement to maintain a dry
work area. No trees will be cut and no grading within riparian areas is proposed. Therefore,
no Roanoke River Buffer impacts are proposed.
Temporary impacts: +/-10ft dewatering (5ft below pipe outlet and 5ft above pipe inlet).
Impervious dikes will be installed in the streambed upstream and downstream of the work
site for containment and to maintain a dry work area. A clean water pump around will be
used to maintain a dry work area. Impervious dike materials will be removed once the work
is complete.
Permanent impacts: There will be no permanent or temporary fill in the stream due to the
pipes remaining the same length. Rip rap will be installed +/-5ft both upstream and
downstream of the pipe for bank stabilization.
Wetland Information: Although this crossing is mapped as having hydric soils (ChA-
Chewacla and Wehadkee), there are no wetlands within the construction footprint.
Cultural Resources: Review of the SHPO GIS mapping reveals no cultural resources, no
historic structures nor properties at this crossing.

Protected species information:
Dwarf wedgemussel: Use of the Programmatic Biological Opinion for Culvert Replacements
and Extensions in Eastern North Carolina, NCDOT Divisions 1-8 (June 13, 2018) provides a
Biological Conclusion of "No Effect" for this species.
Tar River spinymussel: Use of the Programmatic Biological Opinion for Culvert
Replacements and Extensions in Eastern North Carolina, NCDOT Divisions 1-8 (June 13,
2018) provides a Biological Conclusion of No Effect for this species.
Yellow lance: Use of the Programmatic Biological Opinion for Culvert Replacements and
Extensions in Eastern North Carolina, NCDOT Divisions 1-8 (June 13, 2018) provides a
Biological Conclusion of "No Effect" for this species.
Atlantic pigtoe: A US Fish and Wildlife Service (USFWS) proposal for listing the Atlantic
pigtoe (Fusconaia masoni) as an threatened species was published in the Federal Register
in May 22, 2019 The listing will likely become effective by May 22, 2020. Furthermore, this
species is included in USFWS' current list of protected species for Person County. NOTE:
THIS PROJECT WAS COMPLETED IN THE FALL 2018 PRIOR TO PROPOSED LISTING.
