Installing riprap involves placing large, angular rocks or concrete blocks along the slope face and at the toe of the slope to provide protection against erosion and stabilize the slope. Riprap is an effective means of mitigating the risk of slope failure, particularly in areas with high rainfall or heavy runoff. Shotcrete is a form of concrete that can be sprayed onto the slope face to provide additional stability, but it may not be necessary in this case. Revegetation can help to stabilize the slope by establishing a root system to hold soil in place, but it is generally not as effective at preventing slope failure as riprap. Dewatering the slope may be necessary if there is excess groundwater, but it will not necessarily mitigate the risk of slope failure.
