Decade-long plan to save Christchurch's coastal communities from rising seas
Five years after causing anger and anxiety in Christchurch’s coastal communities, the council is taking a new approach to tackle the impact of rising sea levels.
Christchurch City Council is embarking on a lengthy process to figure out how its low-lying coastal and inland communities will adapt to the ramifications of climate change.
Sea levels around the country are projected to rise by about 37 centimetres within 30 years and just over a metre by 2100.
The solutions for each community are likely to be different so the council has split areas into seven different groupings covering 23 communities, and is tackling each grouping separately.
The first communities to undergo planning will be Charteris Bay, Teddington, Allandale and Governors Bay in Lyttelton Harbour, which will happen over the next 18 months to three years.
The council expects it will take at least 10 years to complete adaptation plans for all the city’s coastal areas from Brooklands through to Sumner and across Banks Peninsula.
