Debris slide occurred along the Pachi-Pakke road, caused by the anthropogenic activity such as steep slope cutting for road widening without providing any toe support, and thereby collapse of loose unconsolidated debris.

Construction of retaining structure all along the affected road stretch with sizeable culvert to pass the seasonal discharge of the small nala/chute. Lined toe drain along the road section at the toe of the slide. Channelization of the seasonal nala upto
Toe removal by slope cutting for road widening and predominance of loose unconsolidated debris. Presense of a nala which was oversaturated during peak monsoon.
