4. SEEDBED PREPARATION AND MAINTENANCE - LOOSEN SOIL JUST PRIOR TO SEEDING BY DISKING, RAKING, HARROWING, OR
AN EQUALLY SUITABLE METHOD, ALL SEEDED AREAS WILL BE FERTILIZED, RESEEDED AS NECESSARY AND MULCHED.
S. INSTALL APPLICABLE E&S CONTROL MEASURES PRIOR TO ONSET OF ANY DEMOLITION OR LAND DISTURBING ACTIVITIES. DISTURB ONLY WHAT
IS NECESSARY TO INSTALL APPLICABLE E&S CONTROL MEASURES. VEGETATION TO BE ESTABLISHED ON SLOPES OR OTHER AREAS
WITHIN 21 CALENDAR DAYS OF COMPLETION FOR ANY PHASE OF GRADING ACTIVITIES.
VEGETATIVE SHELF
1, INSTALL !:RIS VIRGINICA (SOUTHERN BLUE FLAG IRIS) OR ANY LOCAL AQUATIC PLANT THAT IS DEEMED SUITABLE BY NCDENR.
CONSULT WITH LOCAL LANDSCAPER FOR APPROPRIATE PLANTING METHODS,
CONSTRUCTION SEQUENCE:
1. OBTAIN £'LAN APPROVAL AND OTHER APPLICABLE PERMITS.
2. FLAG C043TRUCTION LIMITS,
3. INSTALL ROADSIDE CULVERTS WITH INLET AND OUTLET PROTECTION,
4, CLEAR INHAT IS NECESSARY TO INSTALL THE SILT FENCING AND WET DETENTION BASIN WITH A FOREBAY
LOCATED ON THE WESTERN SIDE OF THE SITE. ONCE THE BASIN IS STABILIZED, INSTALL THE RIPRAP OUTLETS
BELOW THE BASIN ENTERING THE DITCH AND THE TEMPORARY DIVERSIONS TO DIRECT FLOW TO BASIN.
5. COMPLETE THE REMAINING SITE CLEARING TOPSOIL AND DEBRIS SHALL BE REMOVED DAILY TO A
NORTH CAROLINA DEPARTMENT OF ENVIRONMENT AND NATURAL RESOURCES (NCDENR) PERMITTED LOCATION.
6. INSTALL THE REMAINING SILT FENCING, CHECK DAMS, CONSTRUCTION ENTRANCE, AND
ROUGH GRADE SITE PRIOR TO ONSET OF LAND DISTURBING (INCLUDING DEMO) ACTIVITIES. DISTURB ONLY WHAT IS
NECESSARY TO INSTALL EROSION CONTROL MEASURES.
7. COMPLEIE GRADING AROUND FENCED AREA AND VEGETATE AND MULCH IMMEDIATELY_
8. STABILIZE ALL DISTURBED AREAS BY SEEDING AND/ OR MULCHING.
9. COMPLETE FINAL GRADING.
10. ALL EROSION AND SEDIMENT CONTROL PROPERTIES WILL BE INSPECTED WEEKLY AND
AFTER EACH SIGNIFICANT RAINFALL EVENT, NEEDED REPAIRS WILL BE MADE IMMEDIATELY.
11. STABILIZE ALL DISTURBED AREAS APPROPRIATELY AND INSTALL PERMANENT VEGETATION AND GRASS —LINED CHANNEL.
IF THE CITE IS TO REMAIN WITHOUT THE PERMANENT SUBSTATION STONE COVER UNTIL SPRING, INSTALL A 25, WIDE
STONE SUFFER ALONG THE PERIMETER ON THE SUBSTATION SITE, AFTER SITE IS STABILIZED, REMOVE ANY SEDIMENT
FROM TFE FOREBAY AND BASIN, THE CHECK DAMS AND PERIMETER SILT FENCING ARE TO REMAIN UNTIL PERMANENT
VEGETATON IS ESTABLISHED.
12. ESTIMATED TIME BEFORE FINAL STABILIZATION - FIVE (5) MONTHS.
GRADING AND BACKFILL MATERIAL:
1, PROPOSED CONTOURS REPRESENT SUBGRADE ELEVATIONS.
2, ALL GRADED AREA WITHIN NEW FENCE SHALL RECEIVE 6" OF STONE (3" CRUSHER RUN AND 3" OF 1 1/2" WASHED
STONE), TO BE PROVIDED BY OTHERS.
3. ALL VEGETATION AND DEBRIS SHALL BE REMOVED FROM THE CONSTRUCTION AREA, SUBGRADE SOILS SHALL BE FREE OF
ORGANIC MATERIAL AND COMPACTED PRIOR TO THE PLACEMENT OF FILL MATERIAL,
4, ALL FILL MATERIAL USED AT THE SITE SHALL UTILIZE A LOW PLASTICITY SOIL (LIQUID LIMIT LESS THAN 50, PLASTICITY
INDEX LESS THAN 25), FREE OF ORGANIC MATERIAL OR DEBRIS.
5. THE GRADING CONTRACTOR SHALL BE RESPONSIBLE FOR HIRING A REPUTABLE GEOTECHNICAL ENGINEERING FIRM,
APPROVED BY THE OWNER OR ENGINEER, TO PERFORM LABORATORY AND FIELD TESTING OF BACKFILL MATERIAL AT THE
CONTRACTORS EXPENSE.
6, A STANDARD PROCTOR COMPACTION TEST SHALL BE PERFORMED BY THE APPROVED GEOTECHNICAL ENGINEERING FIRM
ON THE MATERIAL TO BE USED AS BACKFILL,7. ALL MATERIAL SHALL BE LACER
IVE
LL
8, 1=IELDICOM ACTION TESTS SHALL BEDAKENIFTS BY THE GEOTECHNICAL"ENGINEERING FIRM FROM EACH FILL VOLUa��NOT TO EXCEED 12,
