MAINTENANCE NOTES:
1. INSPECT DIVERSION CHANNELS ONCE A WEEK AND AFTER EVERY RAINFALL. IMMEDIATELY REMOVE SEDIMENT FROM THE FLOW
AREA AND REPAIR THE DIKE.
2. CHECK OUTLETS, AND MAKE TIMELY REPAIRS AS NEEDED TO AVOID GULLY FORMATION. WHEN THE AREA ABOVE THE
TEMPORARY DIVERSION DIKE IS PERMANENTLY STABILIZED, REMOVE THE DIKE, AND FILL AND STABILIZE THE CHANNEL TO BLEND
WITH THE NATURAL SURFACE.
NOTES:
1. CONCRETE WASTE MANAGEMENT PERTAINS TO WASTE FROM CONCRETE
READY -MIX TRUCKS, MASONRY OPERATIONS, AND SIMILAR WASTE.
2. CONCRETE MATERIALS ONSITE, INCLUDING EXCESS CONCRETE, SHALL BE
CONTROLLED AND MANAGED TO AVOID CONTACT WITH SURFACE WATERS,
WETLANDS OR BUFFERS. NO CONCRETE OR CEMENT SLURRY SHALL BE
DISCHARGED FROM THE SITE. ANY HARDENED CONCRETE RESIDUE WILL BE
DISPOSED OF, OR RECYCLED ON SITE, IN ACCORDANCE WITH LOCAL AND STATE
SOLID WASTE REGULATIONS.
3. DISCHARGE OF EXCESS OR WASTE CONCRETE AND/OR WASH WATER FROM
CONCRETE TRUCKS IS ALLOWED AT THE CONSTRUCTION SITE. ONLY
COMMERCIALLY AVAILABLE ABOVE GROUND PORTABLE CONCRETE WASHOUT
CONTAINERS ARE ALLOWED AND SHALL BE PROTECTED FROM VEHICLE TRAFFIC
AND CLEARLY IDENTIFIED BY LEGIBLE SIGNAGE, AND SHALL BE LOCATED
OUTSIDE OF VEGETATED BUFFERS AND AS FAR AS PRACTICABLE FROM
STORMWATER CONVEYANCES AND IMPOUNDMENTS AND WATER BODIES.
PORTABLE CONCRETE WASHOUT CONTAINERS SHALL CONTAIN AND/OR
ACTIVELY MANAGE BOTH, SOLID AND FLUID, COMPONENTS OF THE MIX.
CONCRETE WASHOUT CONTAINERS SHALL BE CLEANED OR EXCHANGED WHEN
THE REMAINING VOLUME IS REDUCED BY 85% TO PREVENT ANY POTENTIAL
OVERFLOW IN A STORM EVENT.
4. ALTERNATIVELY WASTE CONCRETE CAN BE PLACED INTO FORMS TO MAKE RIP
RAP AND/OR OTHER USEFUL CONCRETE PRODUCTS. PORTABLE CONCRETE
WASHOUT CONTAINERS SHALL BE DISPOSED IN ACCORDANCE WITH APPLICABLE
LOCAL, STATE AND FEDERAL REGULATIONS. THE GC IS RESPONSIBLE FOR
ASSURING THAT THESE PROCEDURES, APPLICABLE LAWS, AND ENVIRONMENTAL
REGULATIONS ARE FOLLOWED. THE LOCATION OF CONCRETE WASHOUT
CONTAINERS SHALL BE SHOWN ON THE SITE MAPS.

MAINTENANCE NOTES.
1. INSPECT CHECK DAMS AND CHANNELS AT LEAST WEEKLYAND AFTER EACH SIGNIFICANT (1/2 INCH OR GREATER) RAINFALL EVENT AND REPAIR
IMMEDIATELY. CLEAN OUT SEDIMENT, STRAW, LIMBS, OR OTHER DEBRIS THAT COULD CLOG THE CHANNEL WHEN NEEDED.
2. ANTICIPATE SUBMERGENCE AND DEPOSITION ABOVE THE CHECK DAM AND EROSION FROM HIGH FLOWS AROUND THE EDGES OF THE DAM.
CORRECT DAMAGE IMMEDIATELY. IF SIGNIFICANT EROSION OCCURS BETWEEN DAMS, ADDITIONAL MEASURES CAN BE TAKEN SUCH AS, INSTALLING
A PROTECTIVE RIPRAP LINER IN THAT PORTION OF THE CHANNEL (PRACTICE 6.31, RIPRAP-LINE AND PAVED CHANNELS)
3. REMOVE SEDIMENT ACCUMULATED BEHIND THE DAMS AS NEEDED TO PREVENT DAMAGE TO CHANNEL VEGETATION, ALLOW THE CHANNEL TO
DRAIN THROUGH THE STONE CHECK DAM, AND PREVENT LARGE FLOWS FROM CARRYING SEDIMENT OVER THE DA. ADD STONES TO DAMS AS
NEEDED TO MAINTAIN DESIGN HEIGHT AND CROSS SECTION.
OF PAVEMENT NOTES
USE CLASS B EROSION CONTROL STONE FOR
STRUCTURAL STONE.

MAINTENANCE NOTES:
1. SEDIMENT FENCE- INSPECT SEDIMENT FENCES AT LEAST ONCE A WEEK AND AFTER EACH RAINFALL. MAKE ANY REQUIRED
REPAIRS IMMEDIATELY. SHOULD THE FABRIC OF THE SEDIMENT FENCE COLLAPSE, TEAR, DECOMPOSE OR BECOME INEFFECTIVE,
REPLACE IT PROMPTLY. REMOVE SEDIMENT DEPOSITS AS NECESSARY TO PROVIDE ADEQUATE STORAGE VOLUME FOR THE NEXT
RAIN AND TO REDUCE PRESSURE ON THE FENCE. TAKE CARE TO AVOID UNDERMINING THE FENCE DURING CLEANOUT. REMOVE
ALL FENCING MATERIALS AND UNSTABLE SEDIMENT DEPOSITS AND BRING THE AREA TO GRADE AND STABILIZE IT AFTER THE
CONTRIBUTING DRAINAGE AREA HAS BEEN PROPERLY STABILIZED.

1. PREPARE SOIL BEFORE INSTALLING BLANKETS, INCLUDING ANY NECESSARY APPLICATION OF LIME, FERTILIZER, AND SEED.
2. BEGIN AT THE TOP OF THE CHANNEL BY ANCHORING THE BLANKET IN A 6" DEEP X 6" WIDE TRENCH
WITH APPROXIMATELY 12" OF BLANKET EXTENDED BEYOND THE UP -SLOPE PORTION OF THE TRENCH. ANCHOR THE
BLANKET WITH A ROW OF STAPLES/STAKES APPROXIMATELY 12"APART IN THE BOTTOM OF THE TRENCH. BACKFILL
AND COMPACT THE TRENCH AFTER STAPLING. APPLY SEED TO COMPACTED SOIL AND FOLD REMAINING 12"PORTION
OF BLANKET BACK OVER SEED AND COMPACTED SOIL. SECURE BLANKET OVER COMPACTED SOIL WITH A ROW OF STAPLES/STAKES
SPACED APPROXIMATELY 12" APART ACROSS THE WIDTH OF THE BLANKET.
3. ROLL CENTER BLANKET INDIRECTION OF WATER FLOW IN BOTTOM OF CHANNEL. 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 PER MANUFACTURER'S RECOMMENDATIONS.
4. 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.
5. FULL LENGTH EDGE OF BLANKETS AT TOP OF SIDE SLOPES MUST BE ANCHORED WITH A ROW OF STAPLES/STAKES APPROXIMATELY
12" APART IN A 6" DEEP X 6" WIDE TRENCH. BACKFILL AND COMPACT THE TRENCH AFTER STAPLING.
6. ADJACENT BLANKETS MUST BE OVERLAPPED APPROXIMATELY 4"-6" (DEPENDING ON BLANKET TYPE) AND STAPLED.
TO ENSURE PROPER SEAM ALIGNMENT, PLACE THE EDGE OF THE OVERLAPPING BLANKET (BLANKET BEING INSTALLED ON TOP) EVEN
WITH THE SEAM STITCH ON THE BLANKET BEING OVERLAPPED.
7. IN HIGH FLOW CHANNEL APPLICATIONS, A STAPLE CHECK SLOT IS RECOMMENDED AT 30 TO 40 FOOT (9m-12m) INTERVALS. USE
A DOUBLE ROW OF STAPLES STAGGERED 4" APART AND 4" ON CENTER OVER ENTIRE WIDTH OF THE CHANNEL.
8. THE TERMINAL END OF THE BLANKETS MUST BE ANCHORED WITH A ROW OF STAPLES/STAKES APPROXIMATELY 12" (30cm) APART
IN A 6" DEEP X 6" WIDE TRENCH. BACKFILL AND COMPACT THE TRENCH AFTER STAPLING.
9. PLACE STAPLE/STAKES PER MANUFACTURER'S RECOMMENDATION FOR THE APPROPRIATE CHANNEL FLOW OR SHORELINE
APPLICATION
A
NOTE:
B C CRITICAL POINTS 1. HORIZONTAL STAPLE SPACING SHOULD BE ALTERED
IF NECESSARY TO ALLOW STAPLES TO SECURE THE
A. OVERLAPS AND SEAMS CRITICAL POINTS ALONG THE CHANNEL SURFACE.
B. PROJECTED WATER LINE
C. CHANNEL BOTTOM/SIDE 2. IN LOOSE SOIL CONDITIONS, THE USE OF STAPLE
A SLOPE VERTICES OR STAKE LENGTHS GREATER THAN 6" MAY
B BE NECESSARY TO PROPERLY ANCHOR THE BLANKETS.

NCDENR MAINTENANCE NOTE:
1. INSPECT ROLLED EROSION CONTROL PRODUCTS AT LEAST WEEKLY AND AFTER EACH SIGNIFICANT (1/2 INCH OR GREATER) RAIN
FALL EVENT REPAIR IMMEDIATELY.
2. GOOD CONTACT WITH THE GROUND MUST BE MAINTAINED, AND EROSION MUST NOT OCCUR BENEATH THE RECP.
3. ANY AREAS OF THE RECP THAT ARE DAMAGED OR NOT INCLOSE CONTACT WITH THE GROUND SHALL BE REPAIRED AND STAPLED.
4. IF EROSION OCCURS DUE TO POORLY CONTROLLED DRAINAGE, THE PROBLEM SHALL BE FIXED AND THE ERODED AREA
PROTECTED.
5. MONITOR AND REPAIR THE RECP AS NECESSARY UNTIL GROUND COVER IS ESTABLISHED.
