THE PROPOSED MCALPINE CREEK TRIBUTARY CULVERT REPLACEMENT PROJECT IS LOCATED IN
MECKLENBURG COUNTY, NORTH CAROLINA. THE PROJECT INCLUDES REMOVING ONE CORRUGATED METAL
PIPE CULVERT AND INSTALLING ONE REPLACEMENT REINFORCED CONCRETE PIPE CULVERT. THE DISTURBED
AREA IS 0.20 ACRES. THE PROJECT WILL NOT CHANGE THE EXISTING LAND USE AND WILL REMOVE THE
EXISTING CULVERT 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 03/01/2020 AND BE COMPLETED IN 04/01/2020.

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
