To better understand the potential impacts of coastal erosion, Auckland Council has released a new report, Predicting Auckland’s Exposure to Coastal Instability and Erosion, that assesses the areas of Auckland that are susceptible to both erosion and cliff instability.
The report explains the methodology used in a scientific study to estimate erosion rates for Auckland’s beaches and cliffs and includes regional-scale maps that identify which of Auckland’s coastal areas may be susceptible to coastal erosion and instability over a range of time periods. Councillor Richard Hills, chair of the council’s Environment and Climate Change Committee, says that uncertainty about sea-level rise means coastal erosion rates have historically been difficult to predict.
“Our new Coastal Instability and Erosion report gives us stronger guidance using up to date data,” he says.
