AND WITHIN 24 -HOURS AFTER EACH
RAINFALL EVENT THAT PRODUCES l/ -INCHES
OR MORE OF PRECIPITATION.
MAINTENANCE: REPAIRS SHALL BE MADE
IMMEDIATELY IF ANY TEARS, GAPS, OR
DECOMPOSED AREAS ARE NOTED DURING
INSPECTION. SEDIMENTS SHALL BE
REMOVED WHEN ACCUMULATION HEIGHTS
REACH ONE-THIRD (1/3) THE FENCE
HEIGHT.
3. SEDIMENT TRACKING
DEPOSITING OF SOILS ONTO ADJACENT ROADWAYS
SHALL BE REDUCED BY THE USE OF PERIMETER
CONTROLS.
3.1. CONSTRUCTION ENTRANCE AND EXIT -
A STABILIZED CONSTRUCTION ENTRANCE IS A
TEMPORARY STONE -STABILIZED PAD OR STEEL
SHAKER PLATES. LOCATED AT ALL POINTS OF
VEHICULAR INGRESS AND EGRESS ON A
CONSTRUCTION SITE TO REDUCE THE AMOUNT

ONTO PUBLIC ROADS BY MOTOR VEHICLES,
EQUIPMENT, AND RUNOFF.
LOCATION: AT ALL LOCATIONS WHERE
CONSTRUCTION TRAFFIC WILL BE
ENTERING AND EXITING THE PROJECT SITE.
INSTALLATION SCHEDULE: PERIMETER CONTROLS
SHALL BE INSTALLED PRIOR TO ANY
CLEARING, GRADING, OR DEMOLITION
ACTIVITIES COMMENCE ON THE SITE.
INSPECTION: DAILY AND AFTER EACH RAINFALL
MAINTENANCE: RESHAPE THE STONE PAD AS
NEEDED FOR DRAINAGE AND RUNOFF
CONTROL. RINSE OR REPLACE STONES AS
NEEDED WHENEVER THE ENTRANCE FAILS
TO REDUCE MUD BEING CARRIED OFF SITE
BY VEHICLES. THIS MAY REQUIRE PERIODIC
TOPDRESSING WITH 2 -INCH STONE.
FREQUENT RINSING WILL EXTEND THE
USEFUL LIFE OF STONE. IMMEDIATELY
REMOVE ANY MUD AND SEDIMENT TRACKED
OR WASHED ONTO PUBLIC ROADS BY
BRUSHING OR SWEEPING. REPAIR ANY
BROKEN PAVEMENT IMMEDIATELY.
4. STOCKPILED SEDIMENT, MATERIALS OR DEMOLITION
DEBRIS
ALL STOCKPILES SHALL BE PROTECTED FROM
EROSION WITH TEMPORARY STABILIZATION AND
PERIMETER SILT FENCING PER THE APPROVED
CONSTRUCTION PLANS.
LOCATION: AS DIRECTED BY THE ENGINEER AND
THE CLIENT. SELECT STOCKPILE LOCATION TO
AVOID SLOPES, NATURAL DRAINAGE WAYS, AND
TRAFFIC ROUTES.
INSTALLATION SCHEDULE: MATERIAL STOCKPILES
MAY NOT BE INITIATED UNTIL AFTER ALL
PERIMETER CONTROLS AND SEDIMENT
TRAPS/BASINS ARE IN PLACE.
INSPECTION: INSPECT EVERY 7 CALENDAR DAYS
AND WITHIN 24 -HOURS AFTER EACH RAINFALL
EVENT THAT PRODUCES '/2 -INCHES OR MORE
OF PRECIPITATION.
MAINTENANCE: IF RILLS APPEAR, RE -GRADE AND
RE -STABILIZE IMMEDIATELY. STOCKPILES MAY
BE COVERED WITH MATTING, SHEETING, OR
OTHER MATERIALS TO MINIMIZE EROSION.
MAINTAIN SILT FENCE IN ACCORDANCE WITH
STANDARD NCDEQ EROSION AND SEDIMENT
CONTROL PLANNING AND DESIGN MANUAL AND
DETAILS FROM CONSTRUCTION PLANS.
5. MINIMIZE DUST
DUST CONTROL WILL BE IMPLEMENTED BY
APPLYING WATER AS NEEDED ONCE SITE GRADING
HAS BEGUN AND DURING WINDY CONDITIONS
(FORECASTED OR ACTUAL WIND CONDITIONS OF 20
MPH OR GREATER) WHILE SITE GRADING IS
OCCURRING, AND IN AREAS OF EXPOSED SOIL.
5.1. DUST CONTROL -
LOCATION: ON DISTURBED AREAS THAT HAVE
NOT BEEN STABILIZED WITH VEGETATION.
INSTALLATION SCHEDULE: AS REQUIRED BY
WEATHER CONDITIONS. DUST CONTROL
SHALL BE CONTINUED UNTIL FINAL
STABILIZATION IS ACHIEVED.
INSPECTION: DAILY OBSERVATION OF
CONDITIONS.
6. DISTURBANCE OF STEEP SLOPES
STEEP SLOPES ARE ANY SLOPE EXCEEDING 2:1.
STABILIZATION MEASURES MUST BE INITIATED ON
ANY EXPOSED STEEP SLOPE AREA WHERE
LAND -DISTURBING ACTIVITIES HAVE PERMANENTLY
OR TEMPORARILY CEASED, AND WILL NOT RESUME
FOR A PERIOD OF 14 CALENDAR DAYS.
6.1. EROSION CONTROL BLANKETS -
TEMPORARY EROSION CONTROL BLANKETS
(ECBS) ARE PRODUCTS COMPOSED PRIMARILY
OF BIOLOGICALLY, PHOTOCHEMICALLY OR
OTHERWISE DEGRADABLE CONSTITUENTS SUCH
AS WHEAT STRAW, COCONUT FIBER, OR AGED
CURLED EXCELSIOR WOOD PRODUCT WITH
LONGEVITY OF APPROXIMATELY 1- TO
3 -YEARS. REFER TO APPROVED TECHNICAL
SPECIFICATION AND CONSTRUCTION PLANS
FOR INFORMATION ON MATERIALS. MATERIALS
SHOULD COMPLY WITH LATEST NCDEQ
EROSION AND SEDIMENT CONTROL PLANNING

SEEDING UNTIL THE VEGETATIVE COVER
HAS GROWN AND BECOMES ESTABLISHED.
INSTALL IN ACCORDANCE WITH
MANUFACTURER INSTRUCTIONS.
INSPECTION: INSPECT EVERY 7 CALENDAR
DAYS AND WITHIN 24 -HOURS AFTER EACH
RAINFALL EVENT THAT PRODUCES
%-INCHES OR MORE OF PRECIPITATION.
MAINTENANCE: IF WASHOUT OR BREAKAGE
OCCURS, REPAIR ALL DAMAGED AREAS
IMMEDIATELY BY RESTORING THE SOIL ON
SLOPES OR CHANNELS TO ITS FINISHED
GRADE, REAPPLY SEED, AND REPLACING
THE APPROPRIATE ECB MATERIAL AS
NEEDED. VERIFY MATTING MAINTAINS GOOD
CONTACT WITH THE SLOPE SURFACE.
EROSION SHOULD NOT BE OCCURRING

GRADE CONTROL STRUCTURE NOTES:
1. ALL BOULDERS USED FOR THE GRADE CONTROL STRUCTURE SHALL BE STRUCTUREAL STONE LARGE. CUBICAL OR
RECTANGULAR IN SHOPE COLDER DIMENTIONS L:3.5 - 5.5 FT. W: 2.0 - 3.0 FT, D: 1.5 - 2.5 FT.
2. ALL BEDDING COURSE MATERIAL SHALL CONSISIT OF WELL -GRADED RIPRAP AND EARTH (40% INC DOT CLASS A,
40% INC DOT CLASS B, 20% ASTM #57 OR RQUIVALENT BLEND).
3. ALL COARSE BACKFILL MATERIAL SHALL CONSIST OF WELL -GRADED GRAVEL AND EARTH (40% INC DOT CLASS A,
40% INC DOT CLASS B, 20% ASTM #57).
4. THE GRADE CONTROL STRUCTURE SHALL BE CONSTRUCTED IN AN ELLIPTICAL PATTERN PERPENDICULAR TO
FLOW OF THE SPILLWAY CHANNEL. DIMENSIONS AND SLOPES OF STRUCTURE DESCRIBED IN THE DETAIL MAY
BE ADJUSTED BY ENGINEER TO FIT FIELD CONDITIONS.
5. GAPS BETWEEN BOULDERS SHALL BE MINIMIZED BY FITTING BOULDERS TOGETHER AND PLUGGING WITH
STRUCTURE STONE CLASS A OR CHINKING STONE APPROVED BY DESIGN ENGINEER, AND LINING WITH FILTER
FABRIC.
6. THERE SHALL BE NO DROP GREATER THAN 2.0 FT OVER A SINGLE STEP.
7. NON -WOVEN FILTER FABRIC SHALL BE PLACED ON THE UPSTREAM SIDE OF THE STRUCTURE AND ALONG THE
BASE TO PREVENT WASHOUT OF SEDIMENT THROUGH BOULDER GAPS. FILTER FABRIC SHALL EXTEND FROM
THE BOTTON OF THE FOUNDATION BOULDERS TO THE FINISHED GRADE ELEVATION AND SHALL BE PLACED THE
ENTIRE LENGTH OF THE STRUCTURE. COARSE BACKFILL MATERIAL SHALL BE PLACED UPSTREAM ON THE
STRUCTURE. ALL EXCESS FILTER FABRIC SHALL BE CUT AWAY FROM THE SURFACE OF THE STRUCTURE.
8. THE SCOUR POOL BELOW THE STRUCTURE SHALL BE ARMORED WITH RIPRAP USING THE ROCK BLEND USED
FOR THE SPILLWAY CHANNEL LINING.
9. FOR CONSTRUCTION, THE CONTRACTOR SHALL PREPARE THE AREA OF INSTALLATION BY EXCAVATING OR
FILLING THE WORK AREA TO THE APPROPRIATE ELEVATION. ALL EARTH BENEATH THE STRUCTURE SHALL BE
SUFFICIENTLY COMPACTED WITH THE EXCAVATOR BUCKET OR A VIBRATORY PLATE COMPACTOR TO PREVENT
FUTURE SETTLEMENT OF THE STRUCTURE. PLACE NON -WOVEN FILTER FABRIC OVER THE EXCAVATED AREA.
INSTALL THE GRAVEL BEDDING COURSE AND FOUNDATION BOULDERS SUCH THAT THE BOULDERS ARE BURIED
A MINIMUM OF THE BOULDER DIAMETER. USE COARSE BACKFILL MATERILA TO FILL THE AREA BEHIND THE
STRUCTURE AS ADDITIONAL BOULDERS ARE INSTALLED. BOULDER SETBACK SHALL BE A MINIMUM OF 1.0 FT
AND NO DROP SHALL BE GREATER THAN 2.0 FT. INSTALL BOULDERS IN ROWS UNTIL THE PROFILE INVERT
ELEVATION IS REACHED.
