During this century, according to scientific modelling, climate change is likely to have an increasingly significant impact on Wellington and other coastal cities.
The sea level is predicted to rise by somewhere between 60cm and 1.1 metres. With it, the water table could rise. Potential impacts include erosion and inundation of low-lying coastal land, damage to infrastructure and building foundations, increased flood risks, and increased risks of liquefaction in the event of an earthquake.
A warming climate is also likely to make severe storms more frequent, bringing risks of property and infrastructure damage.
Initial modelling suggests that a 60cm-1.1m sea level rise would mainly affect a small number of coastal areas. Nonetheless, the impact could be significant.
One of the most important tasks facing the Council is to prepare the city for these impacts. We will have to make decisions, for example, about whether coastal land needs to be protected by sea walls, or changes are needed to the stormwater system or other infrastructure.
The first step is to understand the possible impacts, and the measures that can be taken to reduce or mitigate those impacts. Over the next three years, we will:
