First reported 17 Sep 2013•Latest report 30 Dec 2022
Definition
What this concern includes
Includes deficiencies in road drainage, gullies, cambers, slopes, roadway profiles or related permanent engineering controls where they allow rainwater, runoff or other surface water to accumulate, cross or remain on a carriageway, including the anchor's regular water spillage onto the B5302 and comparable failures on other roads.
Not included
Excludes generic road-surface defects, slippery surfaces or flooding hazards where no inadequate drainage or related water-removal control is identified.
Excludes temporary weather conditions where the recurring unsafe condition is not a deficient road-drainage or roadway-engineering control.
Excludes failures limited to warning signage, inspection, reporting or repair processes unless they directly concern the drainage or engineering control that allows hazardous surface water to remain.
Excludes non-road drainage or water hazards, including premises, rail, pedestrian and waterway settings.
