What is a Pothole ? • Hounslow Highways has adopted dimensional definitions for potholes as part of the Safety Inspection Strategy and Plan • Response times and treatment of potholes is based on importance of Carriageways, Footway, Cycle lanes and an assessment of risk • Having assessed and categorised the risk impact and risk probability, the risk matrix is utilised to determine an appropriate response 8
