1. ALL SEDIMENT & EROSION CONTROL MEASURES TO BE IN ACCORDANCE WITH INTERNATIONAL
EROSION CONTROL ASSOCIATION (IECA) AUSTRALIA GUIDELINES AND THE SPECIFICATIONS. THE BASIC
PRINCIPLES ARE TO: BUILDING
- MINIMISE THE AREA OF DISTURBANCE; CONSTRUCTION NOTES: SITE
- CONTROL DRAINAGE PATHS UPSTREAM OF SITE AND AT OUTLETS FROM SITE; MATERIALS LAND
SLOPE
10m (MIN)
- MINIMISE EROSION; ROCK: WELL GRADED, HARD, ANGULAR, EROSION RESISTANT ROCK, NOMINAL DIAMETER OF 40 TO 75mm.
- MINIMISE SEDIMENTATION; FOOTPATH STABILISING AGGREGATE: 25 TO 50mm GRAVEL OR AGGREGATE (IF REQUIRED).
- PROGRESSIVELY REVEGETATE AND REHABILITATE THE SITE GEOTEXTILE FABRIC: HEAVY-DUTY, NEEDLE-PUNCHED, NON-WOVEN FILTER CLOTH (‘BIDIM’ A24 OR SEDIMENT FENCE
2. SEDIMENT & EROSION CONTROL DETAILS SHOWN ARE MINIMUM REQUIREMENTS. IT IS THE EQUIVALENT).
CONTRACTOR'S RESPONSIBILITY TO INSTALL ADDITIONAL CONTROL MEASURES AS DEEMED INSTALLATION FOOTPATH MAKE SAFE FOR
NECESSARY THROUGHOUT CONSTRUCTION. 1. INSPECT ALL SITE ENTRY AND EXIT POINTS PRIOR TO FORECAST RAIN, DAILY DURING EXTENDED PEDESTRIAN TRAFFIC
3. THE CONTRACTOR IS RESPONSIBLE TO MAINTAIN ALL SEDIMENT CONTROL DEVICES IN A FUNCTIONAL PERIODS OF RAINFALL, AFTER RUNOFF-PRODUCING RAINFALL, OR OTHERWISE AT FORTNIGHTLY
ORDER AND REPLACE ALL BLOCKED SEDIMENT DEVICES AS REQUIRED UNTIL SUCCESSFUL OFF INTERVALS. ROADWAY
MAINTENANCE OF WORKS. 2. IF SAND, SOIL, SEDIMENT OR MUD IS TRACKED OR WASHED ONTO THE ADJACENT SEALED ROADWAY,
4. CONSTRUCTION OF ALL SEDIMENT MANAGEMENT DEVICES TO THE SATISFACTION OF THE THEN SUCH MUST BE PHYSICALLY REMOVED, FIRST USING A SQUARE-EDGED SHOVEL, AND THEN A
SUPERINTENDENT. SHALL BE COMPLETED AND EFFECTIVE PRIOR TO: STIFF-BRISTLED BROOM, AND THEN BY A MECHANICAL VACUUM UNIT, IF AVAILABLE.
(c) ROCK PAD SLOPING TOWARD THE ROAD
a. STRIPPING OF TOPSOIL AND GRASS. 3. IF NECESSARY FOR SAFETY REASONS, THE ROADWAY SHALL ONLY BE WASHED CLEAN AFTER ALL
b. BULK EARTHWORKS TO THE SITE. REASONABLE EFFORTS HAVE BEEN TAKEN TO SHOVEL AND SWEEP THE MATERIAL FROM THE ROADWAY.
c. SERVICES INSTALLATION. 4. WHEN THE VOIDS BETWEEN THE ROCK BECOMES FILLED WITH MATERIAL AND THE EFFECTIVENESS OF
d. PAVEMENT CONSTRUCTION. THE ROCK PAD IS REDUCED TO A POINT WHERE SEDIMENT IS BEING TRACKED OFF THE SITE, A NEW 100mm
LAYER OF ROCK MUST BE ADDED AND/OR THE ROCK PAD MUST BE EXTENDED.
5. ALL SEDIMENT MANAGEMENT MEASURES ARE TO REMAIN IN PLACE UNTIL INSTRUCTION IS RECEIVED IN

WRITING FROM THE SUPERINTENDENT TO REMOVE ALL OR PART OF THE SILT CONTROL APPLICATIONS. N.T.S
6. BOTH TEMPORARY AND PERMANENT SEDIMENT MANAGEMENT/EROSION CONTROL DEVICES SHALL BE MAINTAINED IN ACCORDANCE WITH THEIR DESIRED OPERATIONAL CONDITION.
MAINTAINED AT A SUITABLE LEVEL/CONDITION THROUGHOUT CONSTRUCTION TO THE SATISFACTION 6. DISPOSE OF SEDIMENT AND DEBRIS IN A MANNER THAT WILL NOT CREATE AN EROSION OR POLLUTION
OF THE SUPERINTENDENT. SEDIMENT FENCES ARE TO BE CLEANED OUT WHEN CAPACITY IS REDUCED HAZARD.

7. THE BULK EARTHWORKS AND SEDIMENT CONTROL LAYOUT PLAN SHALL BE READ IN CONJUNCTION
WITH THE APPROVED DRAWINGS.
8. PRIOR TO COMMENCEMENT OF CONSTRUCTION APPROVAL IS TO BE OBTAINED FROM THE
SUPERINTENDENT FOR THE LOCATION OF THE SITE ACCESS POINT AND WASH DOWN AREA WHICH ARE
TO BE MAINTAINED THROUGHOUT THE CONSTRUCTION PERIOD.
9. IF EROSION AND SEDIMENT CONTROL DEVICES HAVE BEEN FOUND TO BE DIFFERENT OR FAILED IN
SERVICE, CORRECTIVE ACTION IS TO BE UNDERTAKEN IMMEDIATELY WHICH MAY INCLUDE
AMENDMENTS' ADDITIONS TO THE ORIGINAL APPROVED EROSION CONTROL PLANS. SUCH
AMENDMENTS ARE TO BE APPROVED BY SUPERINTENDENT, IF DEEMED NECESSARY AND RELEVANT.
10. SEDIMENT TRAP TO BE FLOCCULATED AND DE-SILTED AS NECESSARY.
11. WATER QUALITY TESTING / MONITORING TO BE UNDERTAKEN BY CONTRACTOR. 'RETURNS' PLACED AT 20m SPACING (MAX.) IF
3m (MAX.) WITH WIRE BACKING FENCE IS LOCATED ALONG THE CONTOUR.

1.5m (MIN)
2. NORMALLY LOCATED ALONG THE CONTOUR WITH A MAXIMUM CATCHMENT AREA 0.6Ha PER 100m DIRECTION OF FLOW

3. WOVEN FABRICS ARE PREFERRED, NON-WOVEN FABRICS MAY BE USED ON SMALL WORK SITES, I.E.
OPERATIONAL PERIOD LESS THAN 6 MONTHS OR ON SITES WHERE SIGNIFICANT SEDIMENT RUNOFF IS
NOT EXPECTED.
4. WHERE FENCES NEED TO BE LOCATED ACROSS THE CONTOUR THE LAYOUT SHALL CONFORM TO
'TYPICAL LAYOUT' ACROSS GRADE.
5. FENCES ARE REQUIRED 2m MIN. FROM TOE OF CUT OR FILL BATTERS, WHERE NOT PRACTICAL ONE
FENCE CAN BE AT THE TOE WITH A SECOND FENCE 1m MIN AWAY. FENCE SHOULD NOT BE LOCATED
PARALLEL WITH TOE IF CONCENTRATION OF FLOW WILL OCCUR BEHIND THE FENCE.
TEMPORARY CONSTRUCTION ENTRY / EXIT: ALL SUPPORT POSTS PLACED
