The Thames-Coromandel District Council recently gave its consent to a 72 lot extension of the Whitianga Waterways canal housing project, and relied on a “least drama” IPCC projection for sea level rise of 1.06 m out to 2120. That 1m projection complies with nine-year-old 2008 Ministry for the Environment guidelines. But was this good resource and risk management practice? If the Council had instead taken account of high-impact but relatively low-probability projections, as has been proposed by the latest 2017 Draft Ministry guidelines and other 2017 reports from the USA, it would have been forced to conclude that both the subdivision itself and most of Whitianga township will be submerged by rising seas.
Instead, people are going to build houses there, and those houses are going to be underwater in 80 years. And long before then, the council will be forced to redzone them, and the owners will sue the council for deliberately and knowingly consenting them when they shouldn't have. Whoever ends up carrying the can, it is going to be hugely expensive, and hugely wasteful, not to mention ruining people's lives. And all because some property developer wanted to to find a greater fool to realise their asset before it became valueless, and the council was too stupid or too corrupt to say "no".
When that happens, we should send the bill to Paula Bennett, whose suppression of bad news has allowed this decision to be made.
