Marlborough District Sea Level Rise Assessment
Council is conscious of looking at Climate Change hazards from a holistic and collective perspective, potential and emerging hazards will continue to arise in the future not just through short term ‘storms and severe weather events. Rather than respond to these hazards individually, potentially leading to poor future outcomes Council is instead intending to collect additional information to inform a more thoughtful and considered response, this will take time, only with up to date, reliable information can we collectively review risk, vulnerability, consequence, and future options.
In considering additional information collection needs, MfE guidance indicates several elements which Council should consider, see below.
- Coastal erosion caused by storms, sea-level rise and changes in long-term sediment processes and budgets (Coastal morphology).
- Coastal inundation caused by storms and changed climate conditions, or gradual persistent inundation from high tides due to sea-level rise, direct and indirect flooding.
- Rising groundwater and salinisation in coastal lowlands caused by sea-level rise, including land-use impacts.
Additional to this list provided for in guidance Council in engaging with Iwi, community, and stakeholders on the district SLR assessment, Council intends to take on board feedback in considering other additional emerging issues which may also need to be investigated in longer term planning and operational responses.
This will ensure Councils response to building a future DAPP process and DAPP strategy is better ‘prepared’ with a more informed future considered ‘context’.
Driving climate-resilient development in the right locations
With Council, Iwi and the community still some period of time away from beginning the DAPP process, Council must still consider future development.
The built environment has a long lifespan. Decisions we make today about how and where we develop really matter. Buildings, infrastructure and communities must be resilient to the impacts of climate change and help build our capacity to adapt to a changing climate.
To make sure that our planning and infrastructure investment systems guide climate-resilient development in the right places and account for changing risks, the Government has several emerging projects underway, see below:
- Reform of the resource management system to support resilient buildings, infrastructure and communities, and encourage future growth and development in the right locations.
- New direction on natural hazard risk management and climate adaptation through the National Planning Framework
- Reform of institutional arrangements for water services to deliver better health and wellbeing outcomes for our communities and protect our environment for generations to come.
To support Council in its planning effort transitional guidance is provided by MfE until DAPP strategy are in place, these considerations can be found within the latest ‘Interim guidance on the use of new sea-level rise projections’, this latest interim guidance provides an update to earlier 2017 guidance.
See Table 3 page 18 for minimum transitional procedures or RSLR allowances.
