Yeh - read this this morning and at first glance the movements are pretty serious in magnitude. Being so hot on the heals of the Christchurch quakes (and unfortunately with probably many more to come), I am wondering if we have learnt anything! This is another opportunity for the work of surveyors to be showcased - who is going to do that? But we also need to review what is or is not working about our survey system. Initial efforts should rightly be investigating what has happened, and upgrading infrastructure/geodetic coordinates. But there will obviously be effects also on the cadastre and boundaries - it would be a shame to go down the legislative path (as with Chch) to sort that out, and indeed shows the failing of such ad-hoc legislation. It would also be naive to think that cadastral survey work in the affected areas would continue at the same volumes or decrease from pre-earthquake levels. Is it also time for LINZ to look at decentralisation of their office operations and service delivery functions as they are clearly very prone to such events?
It's a very long way for full road construction (widening, sealing, drainage, bridge works etc) over the existing gravelled formation, and although theb land may be Crown, the environmental lobby would have plenty to say on any upgrade - no doubt.
