Technical reports – Coastal Hazard Assessment 2017 CCC


The Council has commissioned several reports over a period of years to gain a comprehensive understanding of sea-level rise and its potential effects.

The 2017 report provides detailed information on inundation (coastal flooding) and erosion for the main inhabited coastal parts of Christchurch and Banks Peninsula. Four climate change and sea-level rise scenarios have been considered out to 2065 and 2120.

The report is the result of a thorough and independent peer review of the 2015 Coastal Hazards Report. A peer review panel made recommendations for changes to the 2015 report and further investigations. These recommendations have been addressed in the 2017 report.

The report has been independently peer reviewed to ensure it met the panel’s recommendations.
