THE FACTS
The severe weather events in early 2023 put flood risk at the forefront for many Aucklanders.
We saw widespread flooding across the region and a demand from the communities most impacted that Auckland Council must prioritise flood resilience.
We listened, and the Making Space for Water programme was

Landslide mapping to be included on Auckland LIM reports from October

The council has done a study of the entire region, giving new information and putting an end to anecdotal information having to be used. "So we've mapped the entire Auckland region all the way across the whole region, all the way from upper Warkworth all the way down to the bottom of Franklin. "And so we've covered everywhere. If you live in Auckland, these maps apply to you," Auckland Council chief engineer Ross Roberts told Nine to Noon. The mapping will be used by the likes of planners, developers, engineers and homeowners. Roberts said it will also play a key part in the council stopping developments in areas susceptible to landslides. He noted the information shows where there is a potential for a problem, rather than a definite problem. "These give an indication of where people might want to investigate further, they are not saying that there is going to be a landslide here. "We're not in a position yet with the science available to be able to forecast landslides. So it's giving people an indication. So they might want to dig further. They might need to get more information," Roberts said. The biggest problem areas were not surprising, Roberts said and they were in areas with big hills. "So you're looking at areas of the Hunua Ranges and you get up into parts of Rodney sort of north of Ōrewa, you see some of the bigger land sites. Auckland's Hunua Ranges.

He said the northern half of Auckland was "particularly vulnerable" to ongoing slow movements that could pose challenges. The mapping also meant there was now consistency with information from across the Auckland region, he said. "We're not just relying on the anecdotal evidence looking at this and saying this looks like a problem area. "Now we've got a map that say, OK, now we could compare one place to another and say 'actually, we know that this is a higher susceptibility, we can start to do something about it'." Roberts said including the new mapping on LIM reports was "the right thing to do". "It's really important that people buying homes understand whether they should be looking harder to understand the problem. "But also we have a legal obligation to, if we have any information about a hazard, we're legally advised to put that on them. "They can look at it and say 'OK, there's a potential problem here, I'll get specialist advice, I'll get an expert to come and give me some information to make sure that in future my house is going to be safe'."

Auckland Council maps out landslide susceptibility

Landslides are among this country's costliest natural hazards. In Auckland, they have wreaked havoc on homes, roads and other infrastructure as well as causing loss of life. The Auckland region includes significant areas of steep terrain with underlying materials that can be prone to slope failure. Recent large storms have caused significant and widespread landslides. Auckland Council has completed a detailed region wide study to map landslide susceptibility, the first since 1997. It will provide information for homeowners, developers and emergency services.
