SUBJECT: Sawyer Creek Culvert Installation
Sawyer Creek, Watauga County
Dear Ms. Fuemmeler:
Biologists with the North Carolina Wildlife Resources Commission (NCWRC) reviewed an
application to replace a culvert and stabilize a small reach of eroding stream, impacting I I I ft of
Sawyer Creek in Watauga County. I visited the site with Melanie Carter on November 26, 2019.
Our comments on this application are offered for your consideration under provisions of the
Clean Water Act of 1977 (33 U.S.C. 466 et. seq.) and Fish and Wildlife Coordination Act (48
Stat. 401, as amended; 16 U.S.C. 661-667d).
There are wild Rainbow Trout and Brown Trout in the project vicinity; however, no moratorium
is required for this project, as delaying the project may cause further destabilization of the
stream. Effective erosion and sediment control on the project are particularly important to
minimize impacts to spawning trout populations
The application proposes to replace a failed 20-ft culvert with an 80-ft culvert and stabilize the
stream immediately upstream and downstream of the culvert with j-hooks and step pools. The
stream runs through a heavily used horse pasture and feeding area. Banks are unstable at the site
of the proposed work, and sediment from the pasture and feeding area is reaching the stream.
There is very little vegetation on the banks and beyond.
The landowner is applying for NRCS funds, which if received, would fence the horses out of the
stream, plant a narrow native buffer, remove a berm, establish alternative watering structures,
and create more stable paths. We strongly recommend that this work be done to lessen the
impacts from the farm on Sawyer Creek. Pasture areas seen were over -used and eroding, and we
recommend that the landowner work with the Soil and Water Conservation District or the
Natural Resource Conservation Service to develop a farm plan to lessen erosion on the farm.

Sawyer Creek Culvert Installation Page 2 November 27, 2019
Sawyer Creek, Watauga County
We offer the following recommendations to minimize impacts to the aquatic community:
1. In -channel work should be accomplished as quickly as possible and vigilance used in
sediment and erosion control during site preparation, construction, and clean up. Disturbed
areas should be seeded, mulched and/or matted as soon as possible, preferably at the end of
each work day.
2. Any erosion control matting used should be free of nylon or plastic mesh, as this type of
mesh netting frequently entangles wildlife and is slow to degrade, resulting in a hazard that
may last for years.
3. Flows should be diverted around the entire work area.
4. Animals should be fenced out of the stream and a native riparian buffer as wide as possible
be established on Sawyer Creek along the entire property.
Thank you for the opportunity to review and comment on this project. Please contact me at
[phone] if you have any questions about these comments.
Sincerely,
Andrea Leslie

SLOPE INSTALLATION INSTRUCTIONS:
NOTE:
*IN LOOSE SOIL CONDITIONS,
THE USE OF STAPLE OR STAKE
LENGTHS GREATER THAN 6" (15
CM) MAY BE NECESSARY TO
I=
PROPERLY SECURE THE
BLANKETS.
1. PREPARE SOIL BEFORE INSTALLING BLANKETS, INCLUDING ANY NECESSARY APPLICATION OF LIME, FERTILIZER, AND SEED.
2. BEGIN AT THE TOP OF THE SLOPE BY ANCHORING THE BLANKET IN A 6" (15 CM) DEEP X 6" (15 CM) WIDE TRENCH WITH APPROXIMATELY 12"
(30CM) OF BLANKET EXTENDED BEYOND THE UP -SLOPE PORTION OF THE TRENCH. ANCHOR THE BLANKET WITH A ROW OF STAPLES/STAKES
APPROXIMATELY 12" (30 CM) APART IN THE BOTTOM OF THE TRENCH. BACKFILL AND COMPACT THE TRENCH AFTER STAPLING. APPLY SEED TO
COMPACTED SOIL AND FOLD REMAINING 12" (30 CM) PORTION OF BLANKET BACK OVER SEED AND COMPACTED SOIL. SECURE BLANKET OVER
COMPACTED SOIL WITH A ROW OF STAPLES/STAKES SPACED APPROXIMATELY 12" (30 CM) APART ACROSS THE WIDTH OF THE BLANKET.
3. ROLL THE BLANKETS IN DIRECTION OF WATER FLOW. BLANKETS WILL UNROLL WITH APPROPRIATE SIDE AGAINST THE SOIL SURFACE. ALL
BLANKETS MUST BE SECURELY FASTENED TO SOIL SURFACE BY PLACING STAPLES/STAKES IN APPROPRIATE LOCATIONS AS SHOWN IN THE STAPLE
PATTERN GUIDE. WHEN USING THE DOT SYSTEM, STAPLES/STAKES SHOULD BE PLACED THROUGH EACH OF THE COLORED DOTS CORRESPONDING
TO THE APPROPRIATE STAPLE PATTERN.
4. THE EDGES OF PARALLEL BLANKETS MUST BE STAPLED WITH APPROXIMATELY 2" - 5" (5 CM - 12.5 CM) OVERLAP DEPENDING ON BLANKET TYPE. S.
CONSECUTIVE BLANKETS SPLICED DOWN THE SLOPE MUST BE PLACED END OVER END (SHINGLE STYLE) WITH AN APPROXIMATE 3" (7.5 CM)
OVERLAP. STAPLE THROUGH OVERLAPPED AREA, APPROXIMATELY 12" (30 CM) APART ACROSS ENTIRE BLANKET WIDTH.
5. PLACE CONSECUTIVE BLANKETS END -OVER -END (SHINGLE STYLE) WITH A 4"-6" OVERLAP. USE A DOUBLE ROW OF STAPLES STAGGERED 4" APART AND
4" ON CENTER TO SECURE BLANKETS.
6 FULL LENGTH EDGE OF BLANKETS AT TOP OF SIDE SLOPES MUST BE ANCHORED WITH A ROW OF STAPLES/STAKES APPROXIMATELY 12"(30CM)
APART IN A 6"(15CM) DEEP X 6"(15CM) WIDE TRENCH. BACKFILL AND COMPACT THE TRENCH AFTER STAPLING.
7. ADJACENT BLANKETS MUST BE OVERLAPPED APPROXIMATELY 2"-5" (5-12.5CM) (DEPENDING ON BLANKETS TYPE) AND STAPLED.

Seedbed Preparation:
Disturbed soils within riparian areas will be amended to provide an
optimum environment for seed germination and seedling growth.
Surface soils will be loose enough for water infiltration and root
penetration. Lime will be added to the soil to ensure a pH level
between 5.5 - 7. Fertilizer (18-46-0) will be added to nutrient deficient
areas. All riparian areas will be raked to loosen compacted soil prior to
seeding.
