(2) HEIGHT OF SEDIMENT FENCE IS NOT TO EXCEED 18" ABOVE THE GROUND SURFACE (3) FILTER FABRIC TO BE CONSTRUCTED FROM CONTINUOUS ROLL CUT TO LENGTH TO AVOID JOINTS. IF JOINTS ARE NECESSARY, FILTER CLOTH IS TO BE SECURELY FASTENED TO SUPPORT POST WITH OVERLAP TO THE NEXT POST. (4) FILTER FABRIC TO BE SUPPORTED BY WIRE MESH FASTENED SECURELY TO THE UPSLOPE SIDE OF THE POSTS USING HEAVY DUTY STAPLES AT LEAST 1" LONG OR TIE WIRES. EXTEND WIRE MESH SUPPORT TO THE BOTTOM OF THE TRENCH. (5) A MAXIMUM OF 8' STAKE SPACING IS ALLOWED WHEN WIRE MESH SUPPORT FENCE IS USED. SUPPORT POST SHOULD BE DRIVEN SECURELY INTO THE GROUND A DISTANCE OF AT LEAST 18"_ (6) EXTRA STRENGTH FILTER FABRIC WITH 6' POST SPACES DOES NOT REQUIRE WIRE MESH SUPPORT FENCE. STAPLE OR WIRE THE FILTER FABRIC DIRECTLY TO POSTS. (7) EXCAVATE A TRENCH APPROXIMATELY 4" WIDE AND 8" DEEP ALONG THE PROPOSED LINE OF POSTS AND UPSLOPE FROM THE BARRIER. (8) BACKFILL TRENCH WITH COMPACT SOIL OR GRAVEL PLACED OVER THE FILTER FABRIC. (9) DO NOT ATTACH FILTER FABRIC TO EXISTING TREES. SEDIMENT FENCE MAINTENANCE: (1) INSPECT SEDIMENT FENCES AT LEAST ONCE A WEEK AND AFTER EACH RAINFALL. MAKE ANY REQUIRED REPAIRS IMMEDIATELY. (2) SHOULD THE FABRIC OF A SEDIMENT FENCE COLLAPSE, TEAR, DECOMPOSE OR BECOME INEFFECTIVE, REPLACED IT PROMPTLY. REPLACE BURLAP EVERY 60 DAYS. (3) 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. (4) 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. NOTES: 1. A STABILIZED ENTRANCE PAD OF # 4 STONE SHALL BE LOCATED WHERE TRAFFIC WILL ENTER OR LEAVE THE CONSTRUCTION SITE ONTO A PUBLIC STREET. 2. FILTER FABRIC OR COMPACTED CRUSHER RUN STONE MAY BE USED AS A BASE FOR THE CONSTRUCTION ENTRANCE. 3. THE ENTRANCE SHALL BE MAINTAINED IN A CONDITION WHICH WILL PREVENT TRACKING OR FLOWING OF SEDIMENT ONTO PUBLIC STREETS OR EXISTING PAVEMENT. THIS MAY REQUIRE PERIODIC TOP DRESSING WITH ADDITIONAL STONE AS CONDITIONS WARRANT AND REPAIR OR CLEANOUT OF ANY MEASURES USED TO TRAP SEDIMENT. 4. ANY SEDIMENT SPILLED, DROPPED, WASHED, OR TRACKED ONTO PUBLIC STREETS MUST BE REMOVED IMMEDIATELY. 5. WHEN APPROPRIATE, WHEELS MUST BE CLEANED TO REMOVE SEDIMENT PRIOR TO ENTERING A PUBLIC STREET. WHEN WASHING IS REQUIRED, IT SHALL BE DONE IN AN AREA STABILIZED WITH CRUSHED STONE WHICH DRAINS INTO AN APPROVED SEDIMENT BASIN 6. SOIL STABILIZATION FABRIC SHALL BE USED. 7. NCDOT MAY REQUIRE A STANDARD COMMERCIAL DRIVEWAY TO ACCESS THE CONSTRUCTION SITE IF THE DRIVEWAY IS ON A THOROUGHFARE. S. INDIVIDUAL LOTS WILL BE PERMITTED BY THE LOT OWNER/BUILDER. z cD r- RIPRAP CONSTRUCTION SPECIFICATIONS: SUBGRADE PREPARATION (1) PREPARE THE SUBGRADE FOR RIPRAP AND FILTER TO THE REQUIRED LINES AND GRADES SHOWN ON THE PLANS. (2) COMPACT ANY FILL REQUIRED IN THE SUBGRADE TO A DENSITY APPROXIMATING THAT OF THE SURROUNDS UNDISTURBED MATERIAL OR OVERFILL DEPRESSIONS WITH RIPRAP. (3) REMOVE BRUSH, TREES, STUMPS, AND OTHER OBJECTIONABLE MATERIAL, CUT THE SUBGRADE SUFFICIENTLY DEEP THAT THE FINISHED GRADE OF THE RIPRAP WILL BE AT THE ELEVATION OF THE SURROUNDING AREA. CHANNELS SHOULD BE EXCAVATED SUFFICIENTLY TO ALLOW PLACEMENT OF THE RIPRAP IN A MANNER SUCH THAT THE FINISHED INSIDE DIMENSIONS AND GRADE OF THE RIPRAP MEET DESIGN SPECIFICATIONS. SAND AND GRAVEL FILTER BLANKET (1) PLACE THE FILTER FABRIC BLANKET IMMEDIATELY AFTER THE GROUND FOUNDATION IS PREPARED. (2) FOR GRAVEL, SPREAD FILTER STONE IN A UNIFORM LAYER TO THE SPECIFIED DEPTH. (3) WHERE MORE THAN ONE LAYER OF FILTER MATERIAL IS USED, SPREAD THE LAYERS WITH MINIMAL MIXING. SYNTHETIC FILTER FABRIC (1) PLACE THE CLOTH FILTER DIRECTLY ON THE PREPARED FOUNDATION. (2) OVERLAP THE EDGES BY AT LEAST TWELVE (12) INCHES, AND SPACE ANCHOR PINS EVERY THREE (3) FEET ALONG THE OVERLAP. (3) BURY THE UPSTREAM END OF THE CLOTH A MINIMUM OF TWELVE (12) INCHES BELOW GROUND AND WHERE NECESSARY, BURY THE LOWER END OF THE CLOTH OR OVERLAP WITH THE NEXT SECTION AS REQUIRED. (4) IF DAMAGE OCCURS TO FILTER FABRIC WHEN PLACING RIPRAP, REMOVE THE RIPRAP AND REPAIR THE SHEET BY ADDING ANOTHER LAYER OF FILTER MATERIAL WITH A MINIMUM OVERLAP OF TWELVE (12) INCHES AROUND THE DAMAGED AREA. STONE PLACEMENT (1) PLACEMENT OF RIPRAP SHOULD FOLLOW IMMEDIATELY AFTER PLACEMENT OF THE FILTER. (2) PLACE RIPRAP SO THAT IT FORCES A DENSE, WELL —GRADED MASS OF STONE WITH A MINIMUM OF VOIDS. (3) PLACE RIPRAP TO ITS FULL THICKNESS IN ONE OPERATION. (4) DO NOT PLACE RIPRAP BY DUMPING THROUGH CHUTES OR OTHER METHODS THAT MAY CAUSE SEGREGATION OF THE STONE SIZES. (5) THE TOE OF THE RIPRAP SHOULD BE KEYED TO A STABLE FOUNDATION AT ITS BASE. (6) THE TOE SHOULD BE EXCAVATED TO A DEPTH ABOUT 1.5 TIMES THE DESIGN THICKNESS OF THE RIPRAP AND SHOULD EXTEND HORIZONTALLY FROM THE SLOPE. (7) THE FINISHED SLOPE SHOULD BE FREE OF POCKETS OF SMALL STONE OR CLUSTERS OF LARGE STONES (8) THE FINAL GRADE OF THE RIPRAP SHOULD BLEND WITH THE SURROUNDING AREA. (9) NO OVERFALL OR PROTRUSION OF RIPRAP SHOULD BE APPARENT. RIPRAP MAINTENANCE: (1) INSPECT RIPRAP PERIODICALLY FOR SCOUR OR DISLODGED STONES.
