the improved design for the embankment toe, which consists of a 1m high triangular rock toe with a 2.7m base. The rock toe has a 0.3m thick and 1.9m wide berm extending into the hydraulic sand-fill. The rock toe is to be wrapped with geo-textile to prevent sand particles from in-filling the voids within the rock toe. In addition, the shoulders of the embankment would be protected by a nominal earth fill layer and turfed to prevent erosion of the hydraulic placed fill during downpours.
