GENERAL NOTES:
1. STREAM ASSESSMENT DATA (LONGITUDINAL PROFILE,
CROSS -SECTIONS, ETC.) PRESENTED HEREIN COLLECTED BY
BFECIBFED.
2. CONTOUR DATA PRESENTED IN THIS DOCUMENT IS TAKEN FROM
NCDOT LIDAR DATA (2' and 10' CONTOURS).
3. HORIZONTAL AND VERTICAL GRID CONTROL TIED TO PROJECT BY
BFED. SURVEY DATA USED FOR DESIGN IS RELATIVE TO ITSELF
AND APPROXIMATELY SET TO REAL WORLD COORDINATES BASED
ON LIDAR DATA.
4. PRIOR TO CONSTRUCTION, BFEC WILL FLAG TREES APPROVED TO
BE REMOVED DURING CONSTRUCTION AS AN EFFORT TO
PRESERVE THE EXISTING RIPARIAN BUFFER.
EROSION AND SEDIMENT CONTROL NOTES:
1. ONCE SITE CONSTRUCTION WITHIN AN AREA HAS CEASED ALL
DISTURBED AREAS WILL BE IMMEDIATELY SEEDED
(TEMPORARY & PERMANENT SEED), MATTED (COIR AND
COCONUT FIBER EROSION CONTROL BLANKET, NAG C700BN),
AND STABILIZED (SEE SHEET 11).
2. LIVE STAKES AND BIODEGRADABLE MATTING STAKES WILL BE
USED TO SECURE THE MATTING.
3. BROADCAST SEEDING RATES WILL BE AS SPECIFIED ON SHEET
11.
4. NATIVE SHRUB AND TREE SPECIES WILL BE PLANTED
THROUGHOUT THE PROJECT AREA ATA RATE OF 350+
STEMS/ACRE, SECURING NEAR BANKAREAS AND PROVIDING
FUTURE SHADING OF CHANNEL (SEE CHANNEL REVEGETATION
DETAIL SHEET 11).
5. PRECAUTIONS WILL BE TAKEN TO KEEP HEAVY EQUIPMENT OUT
OF THE STREAM CHANNEL EXCEPT WHERE ABSOLUTELY

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 SEEDTO
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 INDIRECTION 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 INAPPROPRIATE 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. 5.
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 A4"-6" OVERLAP. USE A DOUBLE ROW OF STAPLES STAGGERED 4" APART AND
4" ON CENTER TO SECURE BLANKETS.
6 FULL LENGTH EDGE OF BLANKETS ATTOP 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.
INSPECTION AND MAINTENANCE:
This consists primarily of two components, stream stabilization
structures (J-Hooks, Cross vanes, etc.) and planting of the stream
banks and riparian areas. In the event that the stream structures
shift, wash away, settle, or otherwise physically cannot function as
designed, contact the area NRCS Agent. If the new plantings
experience a mortality rate of greater than 25%, the dead/dying
plants will need to be replaced.
PERMANENT SEED MIX:
APPLY AT 15 LBS PER ACRE OF DISTURBANCE (per specifications of
seed supplier):
ERNST CONSERVATION SEED MIX ERNMX-178 (FLOODPLAIN MIX)
WHICH INCLUDES THE FOLLOWING SPECIES:
Fox Sedge, Partridge Pea, Dear Tongue, Little Bluestem, Virginia Wild
Rye, Riverbank Wild Rye, Swamp Sunflower, Ox Eye Sunflower, Arrow
Wood, Big Bluestem, Silky Dogwood, Switchgrass, Indiangrass,
Staghorn Sumac, Showy Tick Trefoil, Purple Bergamot, Black Eyed
Susan, Joe Pye Weed , Soft Rush, Giant Ironweed, Tall White Beard
Tongue, Spotted Joe Pye Weed, Bone Set, and Blue False Indigo.
TEMPORARY SEED MIX AND SPECIFICATIONS:
Common Name Scientific Name Rate per Acre Optimal
Planting Dates
Rye grain Secale cereale 30 Ibs Aug 15
- May 15
Browntop millet Urochloa ramosa 10 Ibs May 15
- Aug 15
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.
