APPENDIX B The impact of the weather
Contents Rob Smith’s Member Highway Service Update of 27 th January said.... “Still busy dealing with the impact of the wet weather • The exceptional weather over Christmas and early January is now behind us, it has resulted in a higher number of highway faults than the seasonal average. • Teams that normally delivery Category 2 works and our minor HLB schemes have had to focus their efforts on fixing the high number of highway faults, keeping our highways safe. Potholes - improving repair policy – You said, we did • Our recently launched Defect Management Approach means that more potholes are now repaired permanently first time. This has shown a corresponding reduction in failures of temporary repairs.”

The impact of the weather
How we have coped • Additional Staff providing cover Operations Hub at nights and weekends • Additional Gangs have been working nights and weekends to respond to the call outs • Teams that normally delivery Category 2 works and our minor HLB schemes have been diverted to keeping our highways safe • Drainage crews focused on EA highlighted “areas of risk”
Catching up post emergencies • The Emergency Protocol – KPI suspension – Local Control • Recovery actions – Four road sweeper vehicles are being utilised to clear debris where floods have dissipated – Permanent pothole repair catch up – Large scale resurfacing programmes (re-allocating crews)
The new Defect Management Approach Defect Types • ‘Emergency’ – is a Defect that requires very prompt attention because they represent an immediate or imminent risk • ‘Category 1 Defects’ - are Defects that require prompt attention because they represent an immediate or imminent risk • ‘Category 2 Defects’ are all Defects that are not categorised as Category 1 Defects
