NEW PROPERTY BOUNDARY
EROSION CONTROL NARRATIVE
THIS PROPOSED PROJECT CONSISTS OF CLEARING AND GRADING ACTIVITIES ASSOCIATED WITH
THE CONSTRUCTION OF A CONCRETE PLANT. ACCESS TO THIS SITE WILL BE PROVIDED BY AN
EXISTING DRIVEWAY OFF OF US HIGHWAY 1. A TEMPORARY GRAVEL CONSTRUCTION ENTRANCE
WILL BE PROVIDED OFF OF THE EXISTING DIRT PATH IN THE LOCATION SHOWN AND WILL BE -
INSTALLED PER THE STATES SPECIFICATIONS.
THE EXISTING TOPOGRAPHIC NATURE OF THIS SITE IS GENERALLY LEVEL TO WITH GREATER
ELEVATION RELIEF AS YOU MOVE AWAY FROM THE PROPOSED CONCRETE PLANT AREA. THE
DRAINAGE PATTERNS OF THE SITE CONVEY RUNOFF TO THE EAST AND WEST BASED ON EXISTING _
TOPOGRAPHY. THE PROPOSED GRADING PLAN WILL MAINTAIN THESE DRAINAGE PATTERNS.
THE PROPOSED EROSION CONTROL AND STORMWATER MEASURES AT THE CONCRETE PLANT SITE
WILL CONVEY STORMWATER TO ONE (1) STORMWATER CONTROL MEASURE (SC" WET POND - - -
LOCATED IN THE NORTHWEST CORNER OF THE NEW PARCEL. THE SCM WILL OUTLET TO AN
EXISTING DRAINAGE FEATURE THAT CONVEYS RUNOFF TO AN EXISTING STREAM.
SEDIMENTATION AND EROSION CONTROL WILL BE MAINTAINED ON THIS PROPERTY BY UTILIZING A
TEMPORARY CONSTRUCTION ENTRANCE, SILT FENCING, TREE PROTECTION FENCING, DIVERSION
DITCHES, ROCK CHECK DAMS AND A RISER SKIMMER SEDIMENT BASIN.
CONSTRUCTION SEQUENCE:
1. INSTALL CONSTRUCTION ENTRANCE IN LOCATION SHOWN.
2. INSTALL SILT FENCE BELOW SCM #1.
3. INSTALL RISER, BARREL, AND FLARED END SECTION OF THE SKIMMER BASIN. ATTACH
SKIMMER TO DRAWDOWN DEVICE AND EXCAVATE SEDIMENT BASIN PER THE APPROVED
PLANS. INSTALL BAFFLES.
4. INSTALL TEMPORARY DIVERSIONS, SILT FENCING, OR OTHER MEASURES AS SHOWN ON THE
APPROVED PLAN. CLEAR ONLY AS NECESSARY TO INSTALL THESE MEASURES.
5. CALL FOR ON SITE INSPECTION BY NCDEQ AND OBTAIN CERTIFICATE OF COMPLIANCE.
6. BEGIN CLEARING AND GRUBBING. MAINTAIN DEVICES AS NEEDED.
7. ROUGH GRADE SITE.
8. MAINTAIN EROSION CONTROL DEVICES AS SITE IS BROUGHT TO FINISHED GRADE.
9. BEGIN CONSTRUCTION OF CONCRETE PLANT AND STABILIZE SITE AREAS THAT ARE AT
FINISHED GRADE.
10. WHEN CONSTRUCTION IS COMPLETE AND ALL AREAS ARE STABILIZED COMPLETELY, CALL FOR
INSPECTION BY NCDEQ.
11. IF SITE IS APPROVED, CONVERT TEMPORARY DIVERSIONS TO PERMANENT, REMOVE SILT
FENCING, CONVERT SEDIMENT BASIN TO SCM WET POND AND INSTALL VELOCITY DISSIPATER
AT FLARED END SECTION.
12. WHEN VEGETATION HAS BECOME ESTABLISHED, CALL FOR FINAL SITE INSPECTION BY NCDEQ.
13. OBTAIN CERTIFICATE OF COMPLETION.
GRADING AND EROSION CONTROL NOTES
1. CONTRACTOR SHALL CONSTRUCT DIVERSION DITCHES AS NECESSARY TO ENSURE ALL SEDIMENT IS DIRECTED INTO
EROSION CONTROL DEVICES.
2. CONTRACTOR SHALL VERIFY LOCATION OF ALL EXISTING UTILITIES PRIOR TO CONSTRUCTION. LOCATION OF EXISTING
UTILITIES SHOWN ON PLANS IS BASED ON BEST AVAILABLE INFORMATION BUT CAN BE CONSIDERED ONLY AS
APPROXIMATE.
3. CONTRACTOR SHALL ENSURE GRADING OPERATION IS CONDUCTED IN A MANNER THAT DOES NOT ALLOW ANY SEDIMENT
INTO CREEKS.
4. CONTRACTOR SHALL PROVIDE RIP RAP LINED TAIL DITCHES AT THE STORM DRAINAGE PIPE DISCHARGE POINTS AS
REQUIRED TO ENSURE POSITIVE DRAINAGE.
5. SEDIMENT BASINS SHALL BE KEPT OUT OF WETLAND AREAS.
6. A PRECONSTRUCTION MEETING MAY BE REQUIRED FOR THIS CONSTRUCTION.
7. PERMANENT GROUND COVER SHALL BE ESTABLISHED PER THE STABILIZATION REQUIREMENTS IN THE TABLE LOCATED ON
THIS SHEET.
8. TOPSOIL SHALL BE WASTED OFFSITE OR IN FILL AREAS AS SHOWN. IF AN OFFSITE STOCKPILE IS USED, IT MUST BE
PERMITTED.
9. US HIGHWAY 1 SHALL BE KEPT CLEAN AT ALL TIMES,
10. THE PROJECT WILL MEET ALL REQUIREMENTS RELATIVE TO BEST MANAGEMENT PRACTICES AND ENGINEERED
STORMWATER CONTROL STRUCTURES AS OUTLINED IN NCDEQ EROSION CONTROL MANUAL.
11, CUT AND FILL SLOPES 2:1 OR GREATER SHALL BE STABILIZED WITH PERMANENT SLOPE RETENTION DEVICES OR A
SUITABLE COMBINATION OF PLANTINGS AND RETENTION DEVICES. SLOPES GREATER THAN 3:1 SHALL NOT BE STABILIZED
WITH TURF GRASS BUT MUST BE STABILIZED WITH VEGETATION THAT REQUIRES MINIMAL MAINTENANCE. WEEPING LOVE
GRASS, RED FESCUE, OR OTHER APPROVED VARIETY.
12. THE ESTABLISHMENT OF PERMANENT GROUND COVER WILL BE ESTABLISHED IN 15 WORKING DAYS OR 90 CALENDAR DAYS,
wtIICH EVER IS FIRST.
13. ALL REQUIREMENTS OF THE NPDES PERMITS SHALL BE MET.
