EROSION CONTROL GENERAL NOTES
THE ATTACHED PLANS AND SPECIFICATIONS GIVE THE REQUIREMENTS FOR EROSION CONTROL MEASURES. GRAVEL CHECK DAMS WILL BE LOCATED AT
THE END OF EACH VEGETATED SWALE. SILT FENCE IS LOCATED AROUND THE PERIMETER OF THE SITE AS NOTED ON THE PLANS. THE RUNOFF WILL
BE DIRECTED TO THE TEMPORARY DIVERSION SWALES AND TO THE SEDIMENT CONTROL BASINS DURING CONSTRUCTION. A GRAVEL CONSTRUCTION
ENTRANCE WILL BE CONSTRUCTED AT LOCATIONS INDICATED ON THE PLANS. THE GRADING CONTRACTOR WILL PROVIDE THE MAINTENANCE FOR THE
EROSION CONTROL MEASURES.
1. ALL CONSTRUCTION ACTIVITIES SHALL BE PERFORMED IN COMPLIANCE WITH THE SEDIMENTATION POLLUTION CONTROL ACT of 1973. FLAT SLAB TOP SHALL BEPROVIDED AND
2. ALL LAND DISTURBING ACTIVITIES ARE TO BE PLANNED AND CONDUCTED TO LIMIT EXPOSURE TO THE SHORTEST FEASIBLE TIME. REINFORCED AS REQ'D TO
SUPPORT FRAME
3. ALL DISTURBED AREAS SHALL BE STABILIZED BY A PERMANENT GROUND COVER WITHIN 21 DAYS. AND GRATE UNDER H-20
4. AS SOON AS ALL AREAS ARE PERMANENTLY STABILIZED, ALL PERMANENT MEASURES HAVE BEEN INSTALLED, AND FINAL APPROVAL TRAFFIC LOADING
IS RECEIVED FROM THE LAND QUALITY SECTION, THE TEMPORARY MEASURES MAY BE REMOVED.
PLAN VIEW
5. OVER THE LIFE OF THE PROJECT, THE OWNER SHALL MAKE PERIODIC INSPECTIONS TO EVALUATE THE SUCCESS IN CONTROLLING EROSION
OF SOILS TO OFF -SITE AREAS. IF AREAS ARE FOUND WHERE EROSION IS TAKING PLACE, THE OWNER SHALL TAKE THE NECESSARY AS REQUIRED TO ACCOMMODATE
MEASURES TO REMEDY THE SITUATION.
STORM DRAINS AND INLET FRAMES
CONSTRUCTION SEQUENCE
FRAME AND GRATE RATED FOR
-20 TRAFFIC LOADING
,
1. CONTRACTOR TO NOTIFY N.C. LAND QUALITY SECTION, REGIONAL OFFICE IN WILMINGTON, [phone], PRIOR TO BEGINNING
CONSTRUCTION.
2. INSTALL CONSTRUCTION ENTRANCE, SILT FENCE, AND TEMPORARY DIVERSIONS AS SHOWN ON THE EROSION CONTROL PLAN. PRECAST CONCRETE
3. CONSTRUCT TEMPORARY SEDIMENT TRAPS AS SHOWN ON PLAN, 3:1 SLOPE. BOX RATED FOR MIN.
H-20 TRAFFIC LOADING
4. ROUGH GRADE SITE, MAINTAINING POSITIVE DRAINAGE TOWARDS SEDIMENT TRAPS.
5. DURING CONSTRUCTION OF PERMANENT SWALES, INSTALL TEMPORARY CHECK DAMS AS SHOWN ON PLANS. 12" #57
6. TEMPORARY SEDIMENT TRAPS ARE TO HAVE 1 FOOT OF SEDIMENT CLEANED OUT ONCE ALL CONSTRUCTION IS COMPLETE SO THAT COMPACTED STONE

1. ALL EROSION CONTROL MEASURES WILL BE CHECKED FOLLOWING EVERY RUNOFF -PRODUCING RAINFALL
AND AT LEAST
ONCE EVERY WEEK. NEEDED REPAIRS WILL BE MADE IMMEDIATELY.
2. SEDIMENT WILL BE REMOVED FROM THE SEDIMENT TRAP AND BLOCK AND GRAVEL INLET PROTECTION DEVICE WHEN
STORAGE CAPACITY HAS BEEN APPROXIMATELY 50% FILLED.
3. SEDIMENT WILL BE REMOVED FROM BEHIND THE SEDIMENT FENCE WHEN IT BECOMES 0.5 FT. DEEP
AT THE FACE OF
THE FENCE. THE SEDIMENT FENCE WILL BE REPAIRED AS NECESSARY TO MAINTAIN A BARRIER.
