Progress across the borough

End of Year 4 (Milestone 8) Roads and Footway Improvements

• The condition of roads and footways is measured every

year through detailed technical evaluation by a third-party survey organisation

• The “gap” between current condition and the target is

represented by the Network Performance Gap (NPG)

• The overall target for a compliant network is 0.5 NPG
• The contract started at NPG of 4.58 and is reduced by

each new road or footway completed

• At the end of Year 4 (Milestone 8) the NPG was 0.85
• This represents a 81% improvement in overall condition

– ahead of the contract improvement profile

6

• The LBH road infrastructure asset value increased by £71 million to £778

million in the last financial year.

• Road and Footway works continue through years 4&5 to achieve the

required level of compliance

• Capital works will also take place in the following 20 years based on the

condition of the network each year

• Day to day repairs that qualify for immediate action will continue to be

assessed and actioned.

• Hounslow Highways remains responsible for all streets and their condition

through until 2037

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
