1. PROJECT DESCRIPTION
THE PROPOSED PROJECT INVOLVES PRELIMINARY GRADING OF THE PROPOSED 23.5 ACRE NEUSE2 WATER RECLAMATION
FACILITY (WRF) SITE. ADDITIONALLY, THE PROJECT INCLUDES A NEW GRAVEL ACCESS ROAD AND THE EXTENSION OF A
WATER MAIN TO THE WRF SITE. THE ACCESS ROAD AND WATER MAIN WILL EXTEND APPROXIMATELY 4,200 LF AND WILL BE
CONSTRUCTED WITHIN 50' AND 60' ACCESS AND UTILITY EASEMENTS.
2. SITE DESCRIPTION
THE ACCESS ROAD AND WATER MAIN BEGIN ALONG O'NEIL STREET, APPROXIMATELY 0.3 MILES SOUTH OF ITS INTERSECTION
WITH COVERED BRIDGE ROAD. THE ACCESS AND UTILITY CORRIDOR LARGELY PARALLELS AN EXISTING DUKE ENERGY
POWER LINE EASEMENT BEFORE TURNING TO FOLLOW AN EXISTING ACCESS ROAD TO THE WRF SITE.
3. PERMANENT STABILIZATION
ALL AREAS DISTURBED BY CONSTRUCTION WILL BE STABILIZED WITH PERMANENT SEEDING IMMEDIATELY FOLLOWING FINISH
GRADING. SEEDING WILL CONSIST OF GRASSES TYPICAL OF THE AREA AND INSPECTION AND MAINTENANCE PERFORMED TO
CONFIRM ESTABLISHMENT.
4. PLANNED EROSION AND SEDIMENTATION CONTROL PRACTICES
A. STOCKPILES
STOCKPILES WILL BE USED WHEN THE STORAGE OF EXCESS FILL MATERIAL IS NECESSARY. THE CONTRACTOR WILL BE
RESPONSIBLE FOR LOCATIONS OF ALL STOCKPILES AND ALL ADDITIONAL SEDIMENT AND EROSION CONTROLS MEASURERS
REQUIRED. STOCKPILES SHOULD BE STABILIZED AND/OR SURROUNDED WITH SEDIMENT FENCE TO PREVENT RUNOFF.
B. CONSTRUCTION ENTRANCES
CONSTRUCTION ENTRANCES WILL BE PROVIDED TO REDUCE EROSION OF SEDIMENT INTO WETLANDS AND WATERWAYS
CAUSED BY HEAVY TRUCKS AND MACHINERY ENTERING AND LEAVING THE PROJECT SITE. THIS PRACTICE ALSO PLAYS AN
IMPORTANT ROLE IN COMMUNITY PERCEPTION OF THE PROJECT BY MINIMIZING THE DIRT AND MUD THAT IS TRACKED ONTO
STREETS.
C. SILT FENCE
SEDIMENT FENCE WILL BE CONSTRUCTED AS NECESSARY TO PREVENT SEDIMENT FROM ENTERING DITCHES AND
ADJACENT WATERWAYS.
D. SILT FENCE OUTLETS/STONE DRAINS
SILT FENCE OUTLETS SHALL BE INSTALLED ALONG THE SILT FENCE AT LOCATIONS WERE SIGNS OF CONCENTRATED FLOW
OCCUR AND WILL BE FIELD ADJUSTED AS REQUIRED. THE STONE DRAINS ARE USED TO LET WATER TRAPPED BEHIND THE
SILT FENCE TO ESCAPE DOWNSTREAM HELPING TO PREVENT THE WEIGHT OF DETAINED WATER FROM COLLAPSING THE
SILT FENCE AND ALLOWING TRAPPED SEDIMENT TO ENTER ADJACENT PROPERTY, WETLANDS, AND WATERWAYS.
E. EROSION CONTROL MATTING
EROSION CONTROL MATTING SHALL BE USED ON DISTURBED DITCHES AND SWALES. MATTING IS INTENDED TO STABILIZE
SOIL ON DISTURBED SLOPES WHILE HOLDING SEED AND MULCH IN PLACE ALLOWING VEGETATION TO BECOME
ESTABLISHED. DEPENDING UPON THE SLOPE AND DEPTH OF ANTICIPATED RUNOFF, DIFFERENT MATTING TYPES MAY BE
NECESSARY FOR DIFFERENT APPLICATIONS.
F. EROSION CONTROL STONE
EROSION CONTROL STONE SHALL BE USED ON DISTURBED CREEK AND STREAM CROSSINGS. EROSION CONTROL STONE IS
INTENDED TO STABILIZE SIDES AND BOTTOMS ON DISTURBED CREEK AND STREAM CROSSINGS WHILE ALLOWING
VEGETATION TO BECOME ESTABLISHED. DEPENDING UPON THE SLOPE AND DEPTH OF ANTICIPATED RUNOFF, DIFFERENT
GRADES OF EROSION CONTROL STONE MAY BE NECESSARY FOR DIFFERENT APPLICATIONS.
G. TEMPORARY STREAM CROSSINGS
TEMPORARY STREAM CROSSINGS ARE CONSTRUCTED WHERE CONSTRUCTION EQUIPMENT WILL HAVE TO CROSS THE
EXISTING WATERCOURSE ADJACENT TO THE UTILITY LINE. THIS PRACTICE WILL PROVIDE FOR EROSION AND SEDIMENT
CONTROL AS WELL AS REDUCE THE LIKELIHOOD OF EQUIPMENT BEING IMPACTED IN STREAMBEDS.
H. SEEDING, FERTILIZING, AND MULCHING
SEEDING, FERTILIZING, AND MULCHING ARE A PERMANENT FORM OF EROSION CONTROL. GROUNDCOVER SHALL BE
PROVIDED WITHIN 14 CALENDAR DAYS FOLLOWING COMPLETION OF ANY PHASE OF GRADING. PERMANENT GROUNDCOVER
SHALL BE PROVIDED FOR ALL DISTURBED AREAS WITHIN 14 CALENDAR DAYS FOLLOWING COMPLETION OF CONSTRUCTION
ACTIVITIES.
EROSION CONTROL NOTES:
1. RECEIVING WATERSHED: NEUSE RIVER BASIN
2. RECEIVING WATERCOURSE: NEUSE RIVER WS-IV, C NSW
3. TOTAL LIMITS OF CONSTRUCTION/LIMITS OF DISTURBANCE = 29.3 ACRES.
4. ANY AREA DISTURBANCES BY CONTRACTOR NOT SHOWN ON THE CONSTRUCTION DRAWINGS ARE TO BE PERMITTED
THROUGH THE APPROPRIATE PERMITTING AGENCY.
5. PURSUANT TO G.S. 113A-57(2), THE ANGLE FOR GRADED SLOPES AND FILLS SHALL BE NO GREATER THAN THE ANGLE THAT
CAN BE RETAINED BY VEGETATIVE COVER OR OTHER ADEQUATE EROSION CONTROL DEVICE OR STRUCTURE.
6. PROVIDE A ROLLED EROSION CONTROL PRODUCT (RECP) TO STABILIZE DISTURBED DITCHES IF ANY SIGNS OF SCOURING
ARE EVIDENT EVEN IF NO RECP HAS BEEN SHOWN ON THE CONSTRUCTION DRAWINGS.
7. NO STOCK OR WASTE PILES ARE ALLOWED WITHIN 50' OF STREAMS OR DRAINAGE STRUCTURES.
8. WHERE DEWATERING OF TRENCHES, PITS, AND OTHER EXCAVATIONS BECOMES NECESSARY THE DISCHARGE MUST BE
DIVERTED TO A SEDIMENT FILTER BAG BEFORE BEING DISCHARGED TO THE GROUND.
9. ADEQUATE EROSION CONTROL MEASURES MUST BE INSTALLED, MAINTAINED, AND ADJUSTED AS NEEDED DURING THE
DEMOLITION OR CLEARING AND GRUBBING PHASES AS WELL AS THROUGHOUT THE LIFE OF THE PROJECT AND UNTIL
PERMANENT VEGETATION IS ESTABLISHED.
SEED BED PREPARATION:
1. CHISEL COMPACTED AREAS AND SPREAD TOPSOIL 3 INCHES DEEP OVER ADVERSE SOIL CONDITIONS, WITH STOCKPILED
TOPSOIL. CONTRACTOR SHALL RESERVE SUFFICIENT TOPSOIL FOR SEEDBED PREPARATION.
2. RIP THE ENTIRE AREA TO 6 INCH DEPTH.
3. REMOVE ALL LOOSE ROCK, ROOTS, AND OTHER OBSTRUCTIONS LEAVING SURFACE REASONABLY SMOOTH AND UNIFORM.
4. APPLY AGRICULTURAL LIME, FERTILIZER, AND SUPER -PHOSPHATE UNIFORMLY AND MIX WITH SOIL (SEE BELOW*).
5. CONTINUE TILLAGE UNTIL A WELL -PULVERIZED, FIRM, REASONABLY UNIFORM SEEDBED IS PREPARED 4 TO 6 INCHES DEEP.
6. SEED ON A FRESHLY PREPARED SEEDBED AND COVER SEED LIGHTLY WITH SEEDING EQUIPMENT OR CULTIPACK AFTER
SEEDING.
7. MULCH IMMEDIATELY AFTER SEEDING AND ANCHOR MULCH.
8. INSPECT ALL SEEDED AREAS AND MAKE NECESSARY REPAIRS OR RESEEDINGS WITHIN THE PLANTING SEASON, IF POSSIBLE.
IF STAND IS LESS THAN 60% ESTABLISHED, THE ENTIRE AREA SHALL BE RESEEDED ACCORDING TO SPECIFICATIONS USING
THE ORIGINAL LIME, FERTILIZER AND SEEDING RATES.
