2. INSTALL CONSTRUCTION ENTRANCE WHERE APPLICABLE AT COMMENCEMENT OF ACTIVITIES.
INSTALL SILT FENCE FOR STAGING AREAS TO BE USED AT ONSET OF CONSTRUCTION.
3. LOCATE EQUIPMENT AND MATERIALS IN DESIGNATED STAGING AREAS. CONSULT WITH ENGINEER
BEFORE UTILIZING ANY STAGING AREAS NOT DEPICTED ON PLANS.
4. (IN STREAM) SEDIMENT MANAGEMENT SHALL BE IN PLACE PRIOR TO BEGINNING ANY IN -STREAM
WORK. FLOW DIVERSIONS AND PUMP -AROUND SYSTEMS SHALL NOT BE LEFT UNATTENDED WHILE
SYSTEM IS IN-PLACE/OPERATING.
5. INSTALL SILT FENCE ON STREAM SIDE OF ALL SOIL STOCKPILE AREAS OR STAGING AREAS THAT CREATE
BARE GROUND CONDITIONS.
6. INSTALL APPROPRIATE EROSION AND SEDIMENT CONTROL DEVICES PRIOR TO COMMENCING
EARTHWORK AND IN -CHANNEL WORK. THIS INCLUDES ALL SILT FENCE, TEMPORARY STREAM
CROSSINGS THAT MAY BE USED DURING THE WORK DAY, AND THE PUMP AROUND SYSTEM.
7. EQUIPMENT BROUGHT TO PROJECT SITE SHALL BE CLEAN AND FREE OF LEAKS.
8. CONTRACTOR SHALL PERFORM FUELING AND MAINTENANCE ACTIVITIES AT LEAST 100 FEET AWAY
FROM STREAM AND SHALL MANAGE ALL FLUIDS TO PREVENT LEAKING ONTO GROUND OR TO ALLOW
FOR IMMEDIATE CLEAN-UP.
9. STREAM WORK SHALL BE LIMITED TO AN AREA THAT CAN BE STABILIZED WITH SEED, STRAW AND
MATTING BY THE END OF EACH WORK DAY. ALL DISTURBED STREAMBANKS SHALL BE SEEDED,
STRAWED AND MATTED UNLESS SOD MAT TRANSPLANTS ARE USED IN LIEU OF.
10. HAUL ROADS, SOIL DISPOSAL AREAS, STAGING AREAS AND OTHER UPLAND AREAS DISTURBED DURING
CONSTRUCTION SHALL BE LOOSENED TO COMPACTED DEPTH AND PREPARED FOR PLANTING AND
STABILIZED WITH SEED AND MULCH UPON COMPLETION OF GRADING ACTIVITIES.
11. INTERIM MEASURES MUST BE INSTALLED BY THE CONTRACTOR WHERE SEQUENCING RESULTS IN ANY
RISK OF EROSION AND SEDIMENTATION INTO UNDISTURBED AREAS OR STREAM OR RUNOFF
CONVEYANCES.
12. ALL TEMPORARY ESC PRACTICES, INCLUDING SILT FENCE, CONSTRUCTION ENTRANCES, TEMPORARY
STONE, AND OTHER TEMPORARY MEASURES, SHALL BE REMOVED PRIOR TO DEMOBILIZATION.
THE CONSTRUCTION SEQUENCE IS OUTLINED BELOW BUT MAY BE ADJUSTED BASED ON SITE
CONDITIONS ENCOUNTERED DURING CONSTRUCTION WITH ENGINEER'S APPROVAL.
1. PRIOR TO OR UPON MOBILIZING TO SITE, COMPLETE CHEMICAL TREATMENT OF FESCUE A
MINIMUM OF 3 WEEKS PRIOR TO PHYSICAL EXCAVATION.
2. ALL EROSION AND SEDIMENT CONTROL BEST MANAGEMENT PRACTICES SHALL COMPLY WITH
THE NORTH CAROLINA EROSION AND SEDIMENT CONTROL DESIGN MANUAL. EROSION AND
SEDIMENT CONTROL PRACTICES MUST BE INSTALLED PRIOR TO ANY EARTHWORK
OPERATIONS COMMENCING.
3. THE CONTRACTOR SHALL DISTURB ONLY AS MUCH CHANNEL AS CAN BE STABILIZED WITH
SEEDING, MULCH AND EROSION CONTROL MATTING BY THE END OF EACH WORK DAY.
4. LOCATIONS FOR STAGING AREAS AND TEMPORARY STREAM CROSSINGS HAVE BEEN
PROVIDED ON THE PLANS. ADDITIONAL OR ALTERNATIVE STAGING AREAS AND TEMPORARY
CROSSINGS MAY BE USED BY THE CONTRACTOR DEPENDING ON SITE AND ACCESS
CONDITIONS AT THE TIME OF CONSTRUCTION AND BY APPROVAL OF ENGINEER.
5. THE CONTRACTOR SHALL USE CARE TO AVOID DAMAGING OR REMOVING EXISTING TREES
THAT ARE BEYOND THE LIMITS OF DISTURBANCE.

2. ALL HAUL ROADS SHALL BE MONITORED FOR SEDIMENT LOSS ON A DAILY BASIS. IN THE
EVENT OF SEDIMENT LOSS, SILT FENCE OR OTHER APPROPRIATE SEDIMENT AND EROSION
CONTROL PRACTICES SHALL BE INSTALLED. STABILIZED SILT FENCE OUTLETS SHALL BE
LOCATED AT POINTS OF LOW ELEVATION OR A MINIMUM SPACING OF 150 LINEAR FEET.
3. ANY STOCKPILED MATERIALS NOT USED FOR BACKFILL WITHIN 7 DAYS OF EXCAVATION SHALL
BE STABILIZED WITH TEMPORARY SEED AND STRAW MULCH.
PHASE 2: CHANNEL GRADING
1. DEMARCATE THE EXPECTED WORK AREA FOR THE WORK DAY. ALL NEWLY CONSTRUCTED
CHANNEL MUST BE STABILIZED BY THE END OF EACH WORK DAY. DIVERT WATER AWAY
FROM THE EXPECTED WORK AREA AND TOWARD THE OPPOSITE BANK OF THE EXISTING
CHANNEL (ONLY ONE SIDE OF THE CHANNEL MAY BE GRADED AT A TIME).
2. THE WORK AREA SHOULD BE MANAGED TO KEEP FAST MOVING WATER AWAY FROM THE
ACTIVE EXCAVATION. PROCEED WITH BANK GRADING OR STRUCTURE CONSTRUCTION AND
MONITOR DIVERSION FOR FLOW BYPASSING IT INTO THE WORK AREA. IF DIVERSION
EFFECTIVENESS NEEDS TO BE INCREASED, PUMP WATER FROM UPSTREAM OF WORK AREA
(CLEAN, NON -TURBID WATER) AROUND WORK AREA AND DISCHARGE BACK INTO STREAM
ALONG A STABILIZED OUTLET.
3. STABILIZE ALL GRADED BANKS WITH MATTING BEFORE COMPLETELY REMOVING THE
DIVERSION. DEMARCATE THE NEW WORK AREA AND REPEAT THE ABOVE STEPS FOR THE
NEW WORK AREA.IN THE EVENT OF ANTICIPATED STORM EVENTS, CONDUCT INSTALLATION OF
TEMPORARY ROCK OR OTHER MEASURES AS NECESSARY TO PREVENT DAMAGE TO WORK.
PHASE 2A: BIOENGINEERING AND PLANTING
1. TRANSPLANT SOD MATS AND TRANSPLANT MATERIAL PER DETAIL.
2. ALL ONSITE TRANSPLANTS SUITABLE FOR REUSE SHALL BE HARVESTED AND USED.
3. TREE AND SHRUB PLANTING AND LIVE STAKING SHALL BE COMPLETED AFTER GRADING
OPERATIONS ARE COMPLETE AND DURING THE DORMANT SEASON (GENERALLY BETWEEN
DECEMBER AND APRIL), EXCEPT FOR POTTED PLANT MATERIAL WHICH MAY BE PLANTED
YEAR-ROUND IF WATERED.
PHASE 3: DEMOBILIZATION
5. UPON COMPLETION OF STREAM AND FLOODPLAIN GRADING OPERATIONS, THE
CONSTRUCTION HAUL ROUTES AND STAGING AREAS SHALL BE GRADED, RAKED, SEEDED AND
MULCHED AS NEEDED TO STABILIZE THESE AREAS. ONCE THE SITE IS STABILIZED, SILT FENCES
SHALL BE REMOVED.
6. PREPARE AND RESEED GRASSED FIELD AREAS. REMOVE ALL ROCK FROM AREAS TO
APPROVED ONSITE LOCATION.
7. THE CONTRACTOR SHALL ENSURE THAT THE SITE IS FREE FROM TRASH AND EXCESS
CONSTRUCTION MATERIALS PRIOR TO DEMOBILIZATION OF EQUIPMENT FROM THE SITE.
