There are four key steps in the process to undertake the Coastal Hazard Assessment, which draws on the international risk management standard ISO 31000:2019.
Key steps in undertaking the coastal hazard assessment
Review of direction, guidance, previous studies and new technical information.
Gather input data and identify gaps.
Test and confirm purpose, use, outputs and scenarios.
Identify uncertainties and implications for use.
Determine assessment level and spatial extent.
Develop, test and refine methodology based on the latest techniques and available information.
Provide example outputs.
Using the agreed methodology, undertake technical hazard analysis.
Develop final outputs and supporting communications including:
- Interactive online platform with maps showing modelled hazard for various scenarios.
- Summary report of findings and supporting background reports.
- Technical review register.
The scoping and development of the methodology was completed at the end of 2020, analysis is underway, and the final report is expected to be publicly released in the second half of 2021.
The entire process is being critically reviewed through a rolling technical review by Derek Todd, principal coastal hazard scientist at Jacobs, to provide confidence in the integrity of the technical hazard information. Derek brings a wealth of local knowledge of coastal processes in Canterbury, which has been supplemented with oversight from Environment Canterbury coastal scientists.
We’ve tested the approach with representatives from community groups with interests in technical hazard information and/or environmental issues in late 2020. The purpose of this engagement was to understand potential community perceptions and concerns and to seek assistance in developing communications and supporting information.

There will be further opportunities for these community groups to support the development of the final outputs in stage 4.
Once the 2021 Coastal Hazards Assessment is complete and approved by Council it will be publicly released. There will be a range of resources and communication tools provided to support the public understanding of this technical information along with opportunities for members of the public to talk to and question staff and technical experts.
