Auckland will experience a 3.7-meter king tide. This may lead to partial road closure of the Tamaki Drive on Friday. It may also cause unease for Punakaiki property owners as there will be more chances of erosion.
Last year in September, the motorists had to be detoured because waves broke over the road which has caused flooding.
At that time Auckland Councilor for Orakei, Cameron Brewer said, “Auckland Transport needs to investigate the possibility of raising a key section of low-lying Tamaki Drive across Hobson Bay which closed again today due to flooding.”
He also added, “The Tamaki Drive causeway across Hobson Bay and near the ‘Ngapipi bridge’ is increasingly problematic. It’s getting flooded and is closed with worrying regularity not helped by the fact that it’s sinking.”
Brewer further stated, “Yet for Auckland Transport, the only capital expenditure programmed is $4.2m for a new set of traffic lights at the Tamaki Drive/Ngapipi Road intersection that no one wants. NZTA is busy lifting the level of the north-western causeway because of (the) impact of king tides and the impact on commuters.”
The new wave of king tide is popularly known as Perigean. It is forecasted at the same time when experts are discussing how to adapt to the rising sea level, reported TVNZ.
Professor Jonathan Bambers, a sea level expert, said that sea level would rise 30cm in the next 50 years.
He said, “That might not sound like a lot but it’s around twice of what we’ve seen for the 20th century… Inevitably you’re going to get more coastal flooding any low lying land is going to be susceptible to increased sea levels, coastal infrastructure any houses, any buildings in those areas are going to be affected.”
Punakaiki village is also facing the adverse effects of sea erosion. Last week The Mayor, Deputy Mayor and councilors held a meeting to discuss the sea erosion issue, reported nzherald.co.nz.
Bangladesh is another country which has become very vulnerable to climate change and rising sea levell.
