2. Work Type: ❑✓Private ❑Institutional ❑Government ❑Commercial
3. Project Description / Purpose [PCN Form 133d and B3e]:
The purpose of the proposed project is to relocate approximately 105 linear feet of perennial tributary and stabilize the banks under a
spanned crossing of Joli Cheval Lane in order to prevent scour adjacent to the abutment and insure the long-term stability of the span
structure. The project will be constructed using a mini -excavator and pump -around such that work can be done in the dry. Log vanes
and constructed riffles will be constructed to provide grade control and minimize both lateral and vertical stream migration. Banks will
be stabilized with seed/straw and matting.

D. Impact Justification and Mitigation r
1. Avoidance and Minimization
1a. Specifically describe measures taken to avoid or minimize the proposed impacts in designing project.
Project limits have been designed such that only the reach of stream channel below the span crossing will be relocated in order to move the channel
away from the bridge abutment. Soft (matting, seed, live stakes) stabilization methods will be utilized in order to minimize risk of channel migration
occurring again and avoid discharge of riprap into the stream bed.
1 b. Specifically describe measures taken to avoid or minimize the proposed impacts through construction techniques.
Project will be constructed using a mini -excavator and hand labor in order to minimize risk of materials incidental to construction being transported
into downstream receiving waters.
2. Compensatory Mitigation for Impacts to Waters of the U.S. or Waters of the State
2a. Does the project require Compensatory Mitigation for
impacts to Waters of the U.S. or Waters of the State?
❑ Yes No
2b. If yes, mitigation is required by (check all that apply):

JOLI CHEVAL SPAN
STREAM ENHANCEMENT PLAN
The following plan has been developed to stabilize the Joli Cheval stream reach and to re -position the stream
channel within the Span bridge structure using natural channel design. The channel and floodplain will be re-
graded as depicted in the attached schematics. A bypass pumping operation will be established to construct stream
features in the dry. Constructed riffles and log vanes will be installed to stabilize the stream bed / banks and to
enhance aquatic habitat. All disturbed areas will be re -seeded with a temporary seed and wetland seed mix and
covered with coir fiber matting or jute matting to stabilize the site. Silky dogwood (Cornus amomum), silky
willow (Salix sericea), or other low growing, shade tolerant species will also be planted along channel banks and
benches.
Construction sequencing:
1) Stake out proposed stream thalweg and stream bank alignment.
2) Install pump -around operation and bypass flows around the site.
3) Grade stream, stream bed alignment, and floodplain to elevations specified in the drawings.
4) Install log vanes and constructed riffles. Install filter fabric on up -gradient sides of cross vanes and
underneath stone placed around the vane and on riffles
5) Seed, straw, and mat stream banks and benches.
a. Use Native Wetland Seed Mix to specifications per seed mix. A contractor blend of permanent
and temporary seed shall be applied in addition to the wetland seed mix.
b. Install woven, 100% biodegradable, natural coconut (coir) fiber matting over seeded and strawed
stream banks and benches. The matting shall extend from the toe of the stream bank to 5 feet
beyond the bankfull elevation.
6) Remove bypass pumping operation
7) Seed and straw the remainder of the disturbed areas outside of the stream corridor
8) Install coconut fiber erosion control coir surface blanket (0.5 Ib/yd2) over areas not subject to stream
flow and as needed for sloping areas.
9) Install live stakes or container plants at an average spacing of 3 x 3 feet along the banks of the restored
stream. Planting will be performed during the dormant season.

RE: Joli Cheval
Dear Meagan Jolly
The North Carolina Natural Heritage Program (NCNHP) appreciates the opportunity to provide
information about natural heritage resources for the project referenced above.
Based on the project area mapped with your request, a query of the NCNHP database indicates that
there are no records for rare species, important natural communities, natural areas, and/or
conservation/managed areas within the proposed project boundary. Please note that although there
may be no documentation of natural heritage elements within the project boundary, it does not
imply or confirm their absence; the area may not have been surveyed. The results of this query
should not be substituted for field surveys where suitable habitat exists. In the event that rare
species are found within the project area, please contact the NCNHP so that we may update our
records.
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. Tables of natural areas and conservation/managed areas within a one -mile
radius of the project area, if any, are also included in this report.
If a Federally -listed species is found within the project area or is indicated within a one -mile radius of
the project area, the NCNHP recommends contacting the US Fish and Wildlife Service (USFWS) for
guidance. Contact information for USFWS offices in North Carolina is found here:
httosJ/www.fws.qov/offices/D rtore/ istOffi s fm?stat od = 7.
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.
The INC Natural Heritage Program may follow this letter with additional correspondence if a
Dedicated Nature Preserve, Registered Heritage Area, Clean Water Management Trust Fund
easement, or Federally -listed species are 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 rod nev.butler(o)ncdcr.aov or 919-707-8603.
Sincerely,
NC Natural Heritage Program
