EROSION CONTROL MATTING DETAIL FOR STEEP SLOPES
INSTALLATION:
BLANKET IS DESIGNED TO PROTECT SEED ON SLOPES AND REDUCE OR PREVENT EROSION.
PROPERLY PREPARE, FERTILIZE AND SEED AREA TO BE COVERED BEFORE BLANKET IS APPLIED.
OVERCUT CHANNELS 2" TO ALLOW BULKING DURING SEEDBED PREPARATION. WHEN THE BLANKET
IS UNROLLED, NETTING SHOULD BE ON TOP AND FIBERS IN CONTACT WITH TEH SOIL OVER THE
ENTIRE AREA. IN DITCHES, APPLY BLANKETS IN THE DIRECTION THE WATER FLOWS, BUTTING THEM
AT THE ENDS AND SIDES AND THEN STAPLING. ON SLOPES, APPLY BLANKETS HORIZONTAL TO SLOPE,
OVERLAP ENDS AND SIDES 6" AND THEN STAPLE. VERTICAL INSTALLATION MAY USED UPON ENGINEERS
APPROVAL. INSTALL 6" LONGITUDINAL ANCHOR TRENCHES AT TOP OF SLOPE, AND ANCHOR. LONGITUDINAL
ANCHOR TRENCHES SHOULD BE LOCATED ABOVE THE DESIGN DEPTH OF DITCHES.
STAPLING INSTRUCTIONS:
USE WIRE STAPLES, .091" DIAMETER OR GREATER, "U" SHAPED WITH LEGS 6" LONG OR LONGER
AND 1" CROWN. SIZE AND GAUGE OF STAPLES USED WILL VARY WITH SOIL CONDITIONS. DRIVE STAPLES
VERTICALLY INTO THE GROUND. USE FOUR STAPLES ACROSS AT THE START OF EACH ROLL. FOR SLOPE
INSTALLATION, CONTINUE TO STAPLE ALONG THE LENGTH OF THE ROLL AT 3' TO 5' INTERVALS. FOR
DITCH LINER, STAPLE ALONG THE LENGTH OF THE ROLL AT 3' FT. INTERVALS. ANOTHER ROW OF STAPLES
IN THE CENTER OF EACH BLANKET SHOULD BE ALTERNATELY SPACED BETWEEN EACH SIDE FOR EITHER
SLOPE FOR DITCH. USE A COMMON ROW OF STAPLES ON ADJOINING BLANKETS.
TYPICAL STAPLING PATTERN FOR
HIGH -VELOCITY DITCHES AND
SLOPES.
USE 4 STAPLES ACROSS AT THE
START OF EACH ROLL AND
CONTINUE TO STAPLE THROUGHOUT
THE LENGTH OF THE ROLL AT
1.5 FT. INTERVALS.

PROJECT NARRATIVE
THE PROPOSED GREENSBORO ABANDONMENT PROJECT IS LOCATED IN GUILFORD COUNTY, NORTH
CAROLINA. THE PROJECT INCLUDES REMOVING AN ABANDONED TOWER AND INSTALLING GUY WIRES TO
REPLACE THE STATIC WIRE FROM THE ADJACENT EXISTING TOWERS. THE PROJECT IS LOCATED WITHIN
DUKE ENERGY'S MOWED AND MAINTAINED RIGHT OF WAY. THE DISTURBED AREA IS 1.12 ACRES. THE
PROJECT WILL NOT CHANGE THE EXISTING LAND USE AND WILL REMOVE THE EXISTING TRANSMISSION
TOWER ALREADY IN PLACE. PRIOR TO CONSTRUCTION, A DUKE ENERGY CONSTRUCTION CONTRACTOR WILL
INSTALL EROSION CONTROL MEASURES TO ENCOMPASS THE ANTICIPATED CONSTRUCTION LIMITS.
PREDEVELOPMENT CONDITIONS WILL BE RESTORED AND THE AREA WILL BE STABILIZED PRIOR TO
COMPLETION OF CONSTRUCTION. AN AVOIDANCE AND MINIMIZATION OF DISTURBANCE APPROACH HAS BEEN
INCORPORATED INTO THE DESIGN OF THE EROSION CONTROL MEASURES BY UTILIZING EXISTING ACCESS
POINTS AND STABILIZED RIGHT-OF-WAY ACCESS ROUTES, WHENEVER POSSIBLE. EROSION CONTROL
MEASURES ARE INDICATED HEREIN FOR PERMITTING USE ONLY BY NCDEQ. THE INITIAL PROJECT DURATION
IS ANTICIPATED TO START IN 06/01/2019 AND BE COMPLETED IN 09/01/2019.

5. PAD LOCATION: LOCATE CONSTRUCTION ENTRANCES AND EXITS
TO LIMIT
SEDIMENT FROM LEAVING THE SITE AND TO PROVIDE MAXIMUM UTILITY BY ALL
CONSTRUCTION VEHICLES. AVOID STEEP GRADES AND ENTRANCES
AT CURVES IN
PUBLIC ROADS.
NOTES:
6. WASHING: IF CONDITIONS AT THE SITE ARE SUCH THAT MOST OF
THE MUD AND
SEDIMENT ARE NOT REMOVED BY VEHICLES TRAVELING OVER THE
GRAVEL, THE
TIRES SHOULD BE WASHED. WASHING SHOULD BE DONE ON AN
AREA STABILIZED
WITH CRUSHED STONE THAT DRAINS INTO A SEDIMENT TRAP OR
OTHER SUITABLE
DISPOSAL AREA. A WASH RACK MAY ALSO BE USED TO MAKE WASHING MORE
CONVENIENT AND EFFECTIVE.

OVERCUT CHANNELS 2" TO ALLOW BULKING DURING SEEDBED PREPARATION. WHEN THE BLANKET
IS UNROLLED, NETTING SHOULD BE ON TOP AND FIBERS IN CONTACT WITH TEH SOIL OVER THE
ENTIRE AREA. IN DITCHES, APPLY BLANKETS IN THE DIRECTION THE WATER FLOWS, BUTTING THEM
AT THE ENDS AND SIDES AND THEN STAPLING. ON SLOPES, APPLY BLANKETS HORIZONTAL TO SLOPE,
OVERLAP ENDS AND SIDES 6" AND THEN STAPLE. VERTICAL INSTALLATION MAY USED UPON ENGINEERS
APPROVAL. INSTALL 6" LONGITUDINAL ANCHOR TRENCHES AT TOP OF SLOPE, AND ANCHOR. LONGITUDINAL
ANCHOR TRENCHES SHOULD BE LOCATED ABOVE THE DESIGN DEPTH OF DITCHES.
STAPLING INSTRUCTIONS:
USE WIRE STAPLES, .091" DIAMETER OR GREATER, "U" SHAPED WITH LEGS 6" LONG OR LONGER

VERTICALLY INTO THE GROUND. USE FOUR STAPLES ACROSS AT THE START OF EACH ROLL. FOR SLOPE
INSTALLATION, CONTINUE TO STAPLE ALONG THE LENGTH OF THE ROLL AT 3' TO 5' INTERVALS. FOR
DITCH LINER, STAPLE ALONG THE LENGTH OF THE ROLL AT 3' FT. INTERVALS. ANOTHER ROW OF STAPLES
IN THE CENTER OF EACH BLANKET SHOULD BE ALTERNATELY SPACED BETWEEN EACH SIDE FOR EITHER
SLOPE FOR DITCH. USE A COMMON ROW OF STAPLES ON ADJOINING BLANKETS.
