e Batters to cut embankmenis are not to exceed a slope of 1.5
vertical to 1 horizontal - All details of cut embankments to be
confirmed onsite by engineer.

e Fill embankments should be keyed into the natural ground when
constructed on slopes greater than 15%. Embankment slopes in
fill should not exceed a slope of | vertical to 3 horizontal (where
grassed).

e If fill embankment is suitably rolled during construction,
landscaped with coarse hoop pine bark (or similar) and planted
with suitable shrubs, fill embankment slopes should not exceed a
slope of | vertical to 2 horizontal - all details to be confirmed by
owner.

e Grass to be planted on fill slopes to minimise soil erosion.

e Surface spoon drains at the top and toe of the cut batters/
retaining structures.

® At the ends of the spoon drains provide rock spalls fo disperse
