EROSION CONTROL NOTES AND MAINTENANCE PLAN
1. ALL EROSION AND SEDIMENT CONTROL MEASURES WILL BE CHECKED FOR
STABILITY AND OPERATION FOLLOWING EVERY RUNOFF --PRODUCING RAINFALL, BUT
IN NO CASE, LESS THAN ONCE EVERY WEEK AND WITHIN 24 HOURS OF EVERY
HALF -INCH RAINFALL.
2. ALL POINTS OF EGRESS WILL HAVE CONSTRUCTION ENTRANCES THAT WILL
BE PERIODICALLY TOP -DRESSED WITH AN ADDITIONAL 2 INCHES OF #4 STONE
TO MAINTAIN PROPER DEPTH. THEY WILL BE MAINTAINED IN A CONDITION TO
PREVENT MUD OR SEDIMENT FROM LEAVING THE SITE. IMMEDIATELY REMOVE
OBJECTIONABLE MATERIAL SPILLED WASHED OR TRACKED ONTO THE
CONSTRUCTION ENTRANCE OR ROADWAYS.
3. SEDIMENT WILL BE REMOVED FROM BEHIND THE SEDIMENT FENCE WHEN IT
BECOMES HALF FILLED. THE SEDIMENT FENCE WILL BE REPAIRED AS NECESSARY
TO MAINTAIN A BARRIER. STAKES MUST BE STEEL. STAKE SPACING WILL BE 6
FEET MAX. WITH THE USE OF EXTRA STRENGTH FABRIC, WITHOUT WIRE BACKING.
STAKE SPACING WILL BE 8 FEET MAX. WHEN STANDARD STRENGTH FABRIC AND
WIRE BACKING ARE USED. IF ROCK FILTERS ARE DESIGNED AT LOW POINTS IN
THE SEDIMENT FENCE. THE ROCK WILL BE REPAIRED OR REPLACED IF IT
BECOMES HALF -FULL OF SEDIMENT, NO LONGER DRAINS AS DESIGNED OR IS
DAMAGED.
4. 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. ALL PERIMETER DIKES, SWALES, DITCHES,
PERIMETER SLOPES, ALL SLOPES STEEPER THAN 3' HORIZONTAL TO V VERTICAL
(3:1) AND ALL HIGH QUALITY WATER (HOW) ZONES SHALL BE PROVIDED
TEMPORARY OR PERMANENT STABILIZATION WITH GROUND COVER AS SOON AS
PRACTICABLE BUT IN ANY EVENT WITHIN SEVEN (7) CALENDAR DAYS FROM THE
LAST LAND -DISTURBING ACTIVITY. ALL OTHER DISTURBED AREAS SHALL BE
PROVIDED TEMPORARY OR PERMANENT STABILIZATION WITH GROUND COVER AS
SOON AS PRACTICABLE BUT IN ANY EVENT WITHIN FOURTEEN (14) CALENDAR
DAYS FROM THE LAST LAND -DISTURBING ACTIVITY.
5. GRASS SWALES AND INFILTRATION BASIN INCLUDING SIDES AND BOTTOM WILL
BE ADEQUATELY VEGETATED BEFORE FINAL STORMWATER INSPECTION IS
COMPLETED.

2. CONTRACTOR SHALL COORDINATE WORK WITHIN NCDOT AND LOCAL RIGHT OF
WAYS WITH PROPER AUTHORITIES AND SHALL MEET ANY REQUIREMENTS AS TO
TRAFFIC CONTROL AND CONNECTION TO EXISTING STREETS.
3. CLEARING AND GRUBBING: REMOVE ALL TREES AS REQUIRED UNLESS
OTHERWISE NOTED TO REMAIN, STUMPS, ROOTS, SHRUBBERY, ASPHALT,
CONCRETE, STRUCTURES, BURIED UTILITIES, STORAGE TANKS, ETC. WITHIN LIMITS
OF CONSTRUCTION.
4. STRIPPING: BEFORE EXCAVATING OR FILLING, REMOVE ALL TOPSOIL, WOOD,
LEAVES, AND ANY OTHER UNSUITABLE MATERIAL.
5. MUCKING: REMOVE ANY SOFT, ORGANIC SILT MATERIALS AND EXISTING BURIED
CONSTRUCTION DEBRIS AS REQUIRED AND FILL TO SUBGRADE ELEVATIONS WITH A
CLEAN SELECT -FILL COMPACTED AS SPECIFIED.
6. DISPOSAL: CLEARED, GRUBBED, STRIPPED OR EXCAVATED SPOIL SHALL BE
REMOVED FROM SITE AND DISPOSED OF IN ACCORDANCE WITH ALL APPLICABLE

8. FILL AND COMPACTION. AFTER STRIPPING THOSE AREAS DESIGNATED TO
RECEIVE FILL SHOULD BE PROOFROLLED. THE TOP 8" OF SUBGRADE SHALL BE
COMPACTED TO AT LEAST 98% OF MAXIMUM DENSITY AT OPTIMUM MOISTURE
CONTENT. ANY AREA WHICH PUMPS OR RUTS EXCESSIVELY SHOULD BE
UNDERCUT AND REPLACED WITH A 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 D--698) WITH THE UPPER 12 INCHES OF SUBGRADE BEING
COMPACTED TO 98% 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

100% OF THE STANDARD PROCTOR MAXIMUM DRY DENSITY. 1N AREAS WHERE NO
STRUCTURAL FILL IS TO BE PLACED THE UPPER 12 INCHES OF IN -PLACE
SUBGRADE SHOULD BE COMPACTED TO AT LEAST 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.

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.

STATE PLUMBING CODES. METER AND TAPS SHALL MEET ALL LOCAL
REQUIREMENTS.
16. ALL AREAS SHALL BE GRADED FOR POSITIVE DRAINAGE.
17. CONTRACTOR SHALL NOTE THAT EARTHWORK QUANTITIES ARE HIS
RESPONSIBILITY. PLANS DO NOT REPRESENT A BALANCED EARTHWORK CONDITION.
