- MINIMISE THE AREA OF DISTURBANCE;
- CONTROL DRAINAGE PATHS UPSTREAM OF SITE AND AT OUTLETS FROM SITE; INSTALLATION
- MINIMISE EROSION; 1. INSPECT ALL SITE ENTRY AND EXIT POINTS PRIOR TO FORECAST RAIN, DAILY DURING EXTENDED PERIODS OF

'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
