Permanent cut banks, if required, should not bc stceper than 2-I/2H:1 V in the surficial topsoil nnd weathercd Esperance Sand soils and no steeper tnan 2H:1 V in the undciying Gesh Gspernnce Sand soils. The soil units and the stability of cut slopes should be obscrved and verified by a geotechnicnl engineer during excnvation. Permanent fill embankments reyuircd to sup�rt structurul or tralTic loads should be wnstructed with compacted structur�l till placed over proof-rolled undisturbed, densc to very-dense, fresh Gsperancc Sand deposit aftcr thc surficial unsuitable soils are stripped. Permanent fill to be placed on slopes stecper thun 15°ro grade should bc retained structurally. Sloping ground over which till is to he pinced should be tx�nched with verticnl steps no morc than 4 feet high after stripping of unsuitablc surficial soils.
