Potholes are not historic places. There is no requirement to preserve them for future generations. So before roads are resealed all the lumps and bumps and hollows and pits should be removed. Otherwise all we get is more chips stuck over the same shonky surface.
And roads are thoroughfares for all forms of transport, not just motor vehicles. Next to them, pedestrians are the most numerous and Auckland's traffic engineers should never, ever forget that.
Therefore on the many roads on the island that are too narrow for formal footpaths (and at a minimum of $422 a metre should never be provided with them), the natural grass verges and the tracks worn into them by countless feet should be sacrosanct. Obliterating them with seal that gets wider at every resealing is thoughtless and
stupid. It puts every pedestrian in harm's way.
Auckland City Council, like all New Zealand councils, has a legal responsibility to promote the well-being of the community. That means caring about human beings. Putting them in front of motor vehicles could be regarded as less than careful.
Unless you want them flattened into all those potholes. Cheap filling!
