SITE AND DISPOSED OF IN ACCORDANCE WITH ALL APPLICABLE LOCAL AND STATE CODES.
Z
7. BORROW MATERIAL: THE SITE WORK CONTRACTOR SHALL FURNISH BORROW MATERIAL REQUIRED
o
FROM OFF SITE AND OBTAIN ALL REQUIRED PERMITS ASSOCIATED WITH BORROW OPERATIONS.
N
8. FILL AND COMPACTION: AFTER STRIPPING, THOSE AREAS DESIGNATED TO RECEIVE FILL
SHOULD BE PROOFROLLED WITH A 10-TON VIBRATORY STEEL WHEELED ROLLER TO COMPACT
THE TOP 8" TO AT LEAST 98% OF MAXIMUM DENSITY AT OPTIMUM MOISTURE CONTENT. ANY
O
AREA WHICH PUMPS OR RUTS EXCESSIVELY SHOULD BE UNDERCUT AND REPLACED WITH A
M.
CLEAN, SILTY OR CLAYEY SAND HAVING A UNIFIED SOIL CLASSIFICATION OF SP, SM, OR SC.
FILL MATERIAL 5' OUTSIDE OF BUILDING AREAS SHALL THEN BE PLACED IN LAYERS NOT TO
EXCEED 8" AND COMPACTED TO AT LEAST 95% OF THE STANDARD PROCTOR MAXIMUM DRY
DENSITY (ASTM 0-698) WITH THE UPPER 12 INCHES OF SUBGRADE BEING COMPACTED TO 98
X OF THE STANDARD PROCTOR MAXIMUM DRY DENSITY. FILL MATERIALS WITHIN BUILDING AREAS
TO A LINE OUTSIDE THE BUILDING AREAS SHALL BE PLACED IN LAYERS NOT TO EXCEED 8"
AND COMPACTED TO AT LEAST 98%' OF THE STANDARD PROCTOR MAXIMUM DRY DENSITY (ASTM
D-698) WITH THE UPPER 12 INCHES OF SUBGRADE BEING COMPACTED IN 6 INCH LAYERS TO
100% OF THE STANDARD PROCTOR MAXIMUM DRY DENSITY. IN AREAS WHERE NO STRUCTURAL
FILL IS TO BE PLACED THE UPPER 12 INCHES OF IN -PLACE SUBGRADE SHOULD BE
COMPACTED TO AT 98% OF THE STANDARD PROCTOR MAXIMUM DRY DENSITY. IF THE MATERIAL
IS TOO DRY TO COMPACT TO THE REQUIRED DENSITY EACH LAYER SHALL BE WETTED IN
ACCORDANCE WITH COMPACTION REQUIREMENTS. IF THE MATERIAL IS TOO WET TO SECURE
PROPER COMPACTION, IT SHALL BE HARROWED REPEATEDLY OR OTHERWISE AERATED WITH
SUITABLE EQUIPMENT UNTIL OPTIMUM MOISTURE CONTENT IS OBTAINED, FILL SHALL BE PLACED
IN SUCH A MANNER THAT THE SURFACE WILL DRAIN READILY AT ALL TIMES. SEE STRUCTURAL
NOTES AND SOILS REPORT FOR ADDITIONAL REQUIREMENTS.
9. LAYOUT: THE CONTRACTOR SHALL PROVIDE ALL LAYOUT REQUIRED TO CONSTRUCT HIS WORK.
10. THE CONTRACTOR IS RESPONSIBLE FOR THE LOCATION AND PROTECTION OF EXISTING
UTILITIES DURING CONSTRUCTION.
11. EXISTING BOUNDARY, TOPOGRAPHIC AND TREE SURVEY INFORMATION FROM SURVEY BY
OTHERS, AND PROVIDED BY OWNER.
12. THE CONTRACTOR SHALL VERIFY DIMENSIONS AT JOBSITE.
13. THE CONTRACTOR IS RESPONSIBLE FOR THE COORDINATION OF RELOCATION
OR DISCONNECTION OF ALL EXISTING UTILITIES WITH APPLICABLE AGENCIES AND AUTHORITIES.
14. ALL PAVEMENT AND BASE MATERIALS AND WORKMANSHIP SHALL CONFORM TO NCDOT
STANDARDS.
15. WATER AND SEWER SERVICES SHALL BE INSTALLED TO MEET LOCAL AND STATE PLUMBING
CODES. METER AND TAPS SHALL MEET ALL LOCAL REQUIREMENTS.
16. ALL AREAS SHALL BE GRADED FOR POSITIVE DRAINAGE,
17. THE CONTRACTOR SHALL NOTE THAT EARTHWORK QUANTITIES ARE HIS RESPONSIBILITY.
PLANS DO NOT REPRESENT A BALANCED EARTHWORK CONDITION.
EROSION CONTROL NOTES AND MAINTENANCE PLAN:
1. ALL EROSION AND SEDIMENT CONTROL PRACTICES WILL BE CHECKED FOR STABILITY AND OPERATION
FOLLOWING EVERY RUNOFF -PRODUCING RAINFALL BUT IN NO CASE LESS THAN ONCE EVERY WEEK.
ANY NEEDED REPAIRS WILL BE MADE IMMEDIATELY TO MAINTAIN ALL PRACTICES AS DESIGNED.
2. INSTALL EROSION CONTROL MEASURES BEFORE BEGINNING CONSTRUCTION OR AS SOON
THEREAFTER AS POSSIBLE. ALL EROSION AND SEDIMENT CONTROL PRACTICES WILL BE CHECKED FOR
STABILITY AND OPERATION FOLLOWING EVERY RUNOFF- PRODUCING RAINFALL BUT IN NO CASE LESS
THAN ONCE EVERY WEEK. ANY NEEDED REPAIRS WILL BE MADE IMMEDIATELY TO MAINTAIN ALL
PRACTICES AS DESIGNED.
3. MAINTAIN THE GRAVEL CONSTRUCTION ENTRANCES IN A CONDITION TO PREVENT MUD OR SEDIMENT
FROM LEAVING THE CONSTRUCTION SITE. THE CONTRACTOR SHALL INSPECT THE CONSTRUCTION
ENTRANCES ON A DAILY BASIS. THIS WILL REQUIRE PERIODIC TOP DRESSING WITH ADDITIONAL NO. 4
STONE. ANY OBJECTIONABLE MATERIALS SPILLED, WASHED, OR TRACKED ONTO PUBLIC ROADWAYS
SHALL BE REMOVED IMMEDIATELY.
4. INSTALL EROSION CONTROL MEASURES AROUND THE DROP INLETS AS SHOWN ON THE PLANS TO
TRAP SILT DURING CONSTRUCTION. INSPECT THE EROSION CONTROL AROUND THE INLETS AFTER EACH
RAIN AND MAKE REPAIRS IMMEDIATELY. REMOVE SEDIMENT WHEN IT BECOMES 0.50' DEEP TO
PROVIDE ADEQUATE STORAGE VOLUME FOR SUBSEQUENT RAINS. WHEN THE CONTRIBUTING DRAINAGE
AREA HAS BEEN ADEQUATELY STABILIZED, REMOVE ALL MATERIALS AND ANY UNSTABLE SOIL AND
EITHER SALVAGE OR DISPOSE OF IT PROPERLY. BRING THE DISTURBED AREA TO PROPER GRADE AND
APPROPRIATELY STABILIZE ALL BARE AREAS AROUND THE DROP INLETS.
5. SEDIMENT WILL BE REMOVED FROM BEHIND THE SILT FENCE WHEN IT 13ECOMES 0.5 FT DEEP AT
THE FENCE. THE SEDIMENT FENCE WILL BE REPAIRED AS NECESSARY TO MAINTAIN A BARRIER.
6. NO CUT OR FILL SLOPES SHALL EXCEED A SIDE SLOPE OF 1 VERTICAL TO 4 HORIZONTAL UNLESS
OTHERWISE SPECIFIED ON THE PLAN. ALL SLOPES SHALL BE SEEDED AND STABILIZED WITHIN 15 DAYS.
7. THE STORMWATER PONDS WILL ACT AS SEDIMENT BASINS AND WILL BE CLEANED OUT WHEN THE
LEVEL OF SEDIMENT REACHES 2.0 FT. BELOW THE TOP OF THE RISER. GRAVEL WILL BE CLEANED OR
REPLACED WHEN THE SEDIMENT POOL NO LONGER DRAINS PROPERLY.
8. ALL DISTURBED AREAS SHALL BE SEEDED WITHIN 15 DAYS OF DISTURBANCE. ALL SEEDED AREAS
WILL BE FERTILIZED, RESEEDED AS NECESSARY, AND MULCHED ACCORDING TO SPECIFICATIONS IN THE
VEGETATIVE PLAN TO MAINTAIN A VIGOROUS. DENSE VEGETATIVE COVER.
9. MORE STRINGENT MEASURES SHALL BE USED TO HALT EROSION IF THOSE SHOWN ON THIS PLAN
ARE NOT EFFECTIVE.
10. ALL EROSION SHALL BE CONTROLLED INCLUDING SIDE SLOPES BEFORE THE PROJECT IS COMPLETED.
11. REMOVE TEMPORARY MEASURES UPON COMPLETION OF PROJECT. ALL PERMANENT MEASURES
WILL BE WELL ESTABLISHED BEFORE PROJECT CLOSEOUT.
