3. ENSURE PLASTIC WILL BE CONTINUOUSLY IN CONTACT WITH THE SOIL BY GRADING THE SURFACE,

ENSURE THAT TOPSOIL IS AT LEAST 75mm DEEP.

CAREFULLY FIRST.

LAY FABRIC IN "SHINGLE FASHION”, WITH THE END OF EACH UPSTREAM ROLL OVERLAPPING THOSE
DOWNSTREAM. ENSURE EACH ROLL IS ANCHORED PROPERLY AT ITS UPSLOPE END.

ENSURE FULL WIDTH OF FLOW CHANNEL IS COVERED BY THE PLASTIC.

NOT TO REGULAR SCALE

;SEDIMENT FENCE CONSTRUCTION NOTES

1. CONSTRUCTION SEDIMENT FENCES AS CLOSE AS
POSSIBLE TO BEING PARALLEL TO THE CONTOURS OF THE
SITE, BUT WITH SMALL RETURNS. THE CATCHMENT AREA.
SHOULD BE SMALL ENOUGH TO LIMIT WATER FLOW IF
CONCENTRATED AT ONE POINT.

2. CUT A 150—-mm DEEP TRENCH ALONG THE UPSLOPE
LINE OF THE FENCE FOR THE BOTTOM OF THE FABRIC TO
BE ENTRENCHED.

3. DRIVE TIMBER STAKES INTO GROUND AT 2.5m
INTERVALS (MAX) AT THE DOWNSLOPE EDGE OF THE TRENCH.
4. — FIX SELF—SUPPORTING GEOTEXTILE TO THE UPSLOPE
SIDE OF THE POSTS ENSURING IT GOES TO THE BASE OF
THE TRENCH. FIX THE GEOTEXTILE WITH WIRE RECOMMENDED
BY THE MANUFACTURER. THE USE OF SHADE CLOTH FOR
THIS PURPOSE IS NOT SATISFACTORY.

5. JOIN SECTIONS OF THE FABRIC AT A SUPPORT POST
WITH A 150mm _ OVERLAP.

6. BACKFILL THE TRENCH OVER THE BASE OF THE FABRIC
AND COMPACT IT THOROUGHLY OVER THE GEOTEXTILE.
