Intervention levels

We, as the highway authority, are responsible for the maintenance of the highway, including pavements and footways on all of the roads in the borough which are public highway.

The severity of defects on the footway or carriageway, and therefore the criteria for attention to detail, is determined by the intervention levels which set out the minimum height of trip hazards for paving or the minimum depth across a pothole which require repair.

You may have received a drop card through your door from one of our highways inspectors with a weblink to this page, stating that the defect you have reported is not within intervention levels. Please read on for more information about intervention levels within the borough.

Designated town centres

Footway: minimum 18mm trip hazard

Carriageway: minimum 40mm constant depth across the pothole

All designated town centres are inspected once a month and any intervention level defects noted will be passed to our contractor for repair.

All other borough roads (other than designated town centres)

Footway: minimum 25mm trip hazard

Carriageway: minimum 40mm constant depth across the pothole

All borough roads and footpaths are inspected through a six monthly cyclical inspection regime. Defects noted that are within intervention levels (shown above) are passed to our contractor for repair.
