Shoreline adaptation plans (SAPs) are strategic documents that support the sustainable management of Auckland Council owned land and assets on the coast for the next 100 years.
These plans consider the potential impacts of coastal erosion, coastal inundation, rainfall flooding, and climate-change impacts (including sea level rise) and seek to provide an adaptive planning approach that is focused on the needs and values of local iwi and local communities.
Acknowledging the environmental and landscape value of the shoreline, SAPs also work to promote the preservation, enhancement, and ecological restoration of the coastal environment for future generations.
Tonkin + Taylor was engaged by Auckland Council to conduct a risk assessment to measure the exposure of public land and assets in coastal areas to three natural hazards – coastal inundation, coastal erosion susceptibility, and rainfall flooding.
This includes the escalating impacts of climate change and the changing likelihood of such events across the different timescales – short (20 year), medium (60 year), and long term (100 year).
The assessment includes a qualitative assessment of asset vulnerability and potential consequences across a range of exposure bands for those time periods.
