REVIEW EROSION AND SEDIMENTATION CONTROL REQUIREMENTS AT PRECONSTRUCTION CONFERENCE. 3. INSTALL GRAVEL CONTROL ENTRANCE. 4. ERECT SILT FENCING. 5. CLEAR AND GRUB SITE. 6. EXCAVATE STORMWATER RETENTION POND AND STABILIZE. 7. CONSTRUCT PROJECT SWALES TO DISCHARGE TO STORMWATER RETENTION POND. 8. INSTALL CHECK DAMS. 9. ROUGH GRADE SITE. 10. INSTALL GRAVEL SURFACING. 11. FINISH GRADE AND VEGETATE SITE. 12. STABILIZE WITH SEED AND MULCH ALL AREAS NOT TO BE FURTHER DISTURBED BY CONSTRUCTION ACTIVITIES. 13. REMOVE ANY ACCUMULATED SEDIMENT FROM STORMWATER RETENTION POND. 14. ADDITIONAL MISCELLANEOUS EROSION AND SEDIMENTATION CONTROL MEASURES MAY BE REQUIRED WHEN DEEMED NECESSARY BY THE PROJECT ENGINEER, THE NCDENR'S LAND QUALITY SECTION OR THE CONTRACTING OFFICER. 15. REMOVE GRAVEL CONTROL ENTRANCE, SILT FENCING AND STONE CHECK DAMS AT COMPLETION OF CONSTRUCTION AND THE ESTABLISHMENT OF FINAL VEGETATION. MAINTENANCE PLAN 1. REMOVE SEDIMENT FROM BEHIND SILT FENCING AND CHECK DAMS WHEN IT ACCUMULATES TO SIX INCHES. 2. ALL AREAS SHALL BE FERTILIZED, SEEDED, RESEEDED AS NECESSARY, AND MULCHED ACCORDING TO SPECIFICATIONS IN THE VEGETATION PLAN IN ORDER TO ESTABLISH AND MAINTAIN A VIGOROUS, DENSE VEGETATIVE COVER. 3. ANY SEDIMENT TRACKED ONTO THE ADJACENT ASPHALT ROAD SHALL BE REMOVED ON A DAILY BASIS. 4. STORMWATER RETENTION POND SHALL BE USED AS A TEMPORARY SEDIMENT TRAP. UPON COMPLETION OF CONSTRUCTION, ALL SEDIMENT SHALL BE REMOVED FROM THE STORMWATER RETENTION POND TO RESTORE IT TO THE DESIGN DEPTHS. SPECIAL SEEDING NOTE: THE ANGLE FOR GRADED SLOPES AND FILL SHALL BE NO GREATER THAN THE ANGLE THAT CAN BE RETAINED BY VEGETATIVE COVER OR OTHER ADEQUATE GROUND COVER. GROUND STABILIZATION AND SEEDING SHALL BE PROVIDED WITHIN 7 CALENDAR DAYS OF COMPLETION OF ANY PHASE OF GRADING. ADDITIONALLY, WITHIN 15 WORKING DAYS OR 30 CALENDAR DAYS FROM THE COMPLETION OF THE PROJECT (WHICHEVER IS SHORTER), PERMANENT GROUND COVER SHALL BE ESTABLISHED. NOTE: ALL FILL MATERIAL NEEDED TO CONSTRUCT THIS PROJECT SHALL BE OBTAINED FROM THE FRENCH CREEK BORROW PIT OR FROM A PROPERLY PERMITTED COMMERCIAL BORROW PIT AT THE CONTRACTOR'S OWN EXPENSE. NOTE: THE PROJECT NPDES CONSTRUCTON PERMIT REQUIRES THAT EROSION CONTROL DEVICES AND STORM WATER OUTFALLS BE INSPECTED WEEKLY AND WITHIN 24 HOURS OF A 1/2-INCH RAIN EVENT. IT SHALL BE THE RESPONSIBILITY OF THE CONTRACTOR TO CONDUCT THESE INSPECTIONS AND MAINTAIN RECORDS UNTIL THE AREA HAS STABILIZED, EVIDENT BY 95% VEGETATIVE GROWTH FOR AREAS RECEIVING SEEDING. TO FACILITATE RAINFALL MONITORING, A RAIN GAUGE IS REQUIRED TO BE ONSITE. ONCE STABILIZATION HAS BEEN ACCOMPLISHED, INSPECTION RECORDS ARE TO BE FORWARDED TO THE CONTRACTING OFFICER AND ALL TEMPORARY EROSION CONTROL MEASURES REMOVED. THE CONTRACTOR IS RESPONSIBLE FOR MAINTAINING COMPLIANCE WITH ALL PERMITS AND PLANS. ANY CHANGES MUST BE APPROVED BY THE STATE PRIOR.
