Nelson City Council’s proposed library at a riverside site near the current library is likely to be pulled out of insurance amid mounting flood risks, according to a climate economist.

Nelson’s homes are at risk of losing insurance by 2050, with a multi-million dollar library proposal in the CBD among properties at risk of insurance withdrawal, a climate economist warns.

Victoria University of Wellington researcher Belinda Storey, who spoke at a Nelson-based webinar on Wednesday, said properties in an area prone to flooding every 100 years in Nelson were likely to lose their insurance within 30 years.

Approximately 4,500 Nelson properties were identified as at risk of coastal flooding during a 100-year event – known as the 1% DWA (probability of annual exceedance) – under rising water level scenarios. the sea up to 2 m.

It was one of the modeling scenarios released by Nelson City Council last year.

This week, the council informed homeowners that their properties were among more than 5,000 identified as potentially affected by river flooding modeling, revised to account for climate change scenarios.

A Storey report released in 2020 found that at least 10,000 homes in New Zealand’s four largest cities would be effectively uninsurable in three decades, with Wellington being the first to start losing access to affordable insurance – in 15 years old.

In the webinar hosted by the local branch of the Institute of Architects New Zealand and Engineering New Zealand, Storey said Nelson is most aligned with Auckland because Nelson has quite a large tidal range.

When asked if a $ 44 million library the council is proposing to build beside the Nelson Maitai River could be threatened with insurance withdrawal, Storey said she had not undertaken an analysis location specific.

“But from what is described, it suggests it’s likely.”

Nelson City Council's proposed new riverside library at the corner of Halifax and Trafalgar streets is in an area at risk of coastal flooding during a current event, with a 1% change each year , according to the modeling of the board.

The council’s coastal flood maps showed that the proposed library site at the corner of Halifax and Trafalgar streets was in an area of ​​the CBD where flooding can occur as part of a current 1% AEP event. .

Residents of Ruby Bay are battling the storm surge associated with former Tropical Cyclone Fehi, which hit Tasman District in February 2018.

Story told Thing it was likely that a number of homeowners at risk of flooding would lobby their local government for public defense spending.

“It doesn’t hold.”

“When that defense fails, and it inevitably will, there are more assets and more people at risk.”

While it would make sense for the company to pay to defend some hard-to-move critical infrastructure, Storey discouraged this for “whole areas” like a CBD.

“We may need to step up in the safest places. “

Ex-Cyclone Fehi hit the suburb of Glenduan, north of Nelson, in 2018. A rock pavement has since been built which the council says is designed to protect the seaside road from a 5 to 5 storm. 10 years.

Storey had developed a model of “climate leases”, largely aimed at preventing new construction in dangerous places.

Leases impose a time limit on a property, with rights of use expiring after that date.

“A word of advice might say … yes, you can rebuild there, but you must have vacated the property within that time, as this is the period in which we believe safe occupancy can take place.”

The mechanism would encourage innovation around mobile homes, Storey said.

If people did not bear the risk with their financial decisions, there was “an implicit expectation that society will bail them out,” she said.

For people who already owned properties as a financial investment in flood-prone areas, she advised undertaking research “to understand the amount that climate risk is not currently built into the value of this property.”

If people wanted to stay on a property because they had an emotional connection to it, she advised making sure they understood how long it would be safe to occupy.
