While the rate and exact amount of future sea level rise is uncertain, we do know that rising sea levels will have increasing implications for development and infrastructure in coastal areas along with environmental, cultural, economic, and societal effects. By coming together this year to look at what we know about sea level rise and coastal hazards in Tasman, and our options for adapting, we'll be better prepared for future decision-making.

There are a mix of options for responding to sea level rise and coastal hazards. All have challenges and opportunities. The options sit broadly under four categories; accommodate, protect, avoid, and retreat. You can read more about these options in our recently published report: Coastal Management Options for Tasman Bay/Te Tai o Aorere and Golden Bay/Mohua 2021.

September online events

Thank you to the 160 people who tuned in to one of our three September webinars to find out more about the Coastal Management Project, what’s at risk from sea level rise and coastal hazards, and our options for responding. Below is a recording of the 7pm live webinar on the 28th of September with presenters Dr Rob Bell, Diana Worthy, Glenn Stevens.

What are your views on the options for responding to sea level rise and coastal hazards?

We want to know your views on the options presented or if there are other options you think we should consider. Check out examples of options below and share your thoughts and ideas.

Thank you to those who shared their views with us. What we learned will help to inform the next phases of the Coastal Management Project, particularly future discussions of options at a local level. The decisions we make over the coming years will affect generations to come – shaping the places we live, work, and value.

We also really appreciated the dozens of responses given through the full feedback form.

Elspeth Collier says:

Estuarine saltmarsh plants and sediment trap and store carbon. Suitable low lying land should be identified and set aside now to allow for inland migration of saltmarsh, ahead of rising sea levels.

Jenny Easton says:

I lived in 39 Tahi St Mapua for a long time, left for higher ground in 2011 having seen SLR and coastal erosion. Managed retreat for lowlying Mapua is the only fair and longterm answer.

Gillian Pollock says:

Nature must be able to adapt naturally to rising tides. Coastal bird life must have adequate feeding and nesting areas along the shoreline. All structures within storm tide zones should be removed

Retreat. We can not fight nature. Even if you put up walls to stop it. The sea will always win, retaining walls will end up in the ocean, houses will be too. Environmental disaster in the making.

Danielle says:

I have several properties in the coastal areas and I firmly believe the choice should be mine as a land owner as to whether I build at sea ground level or not. I want to build at ground level still.

Darrin says:

It's a have. This and global warming are a have. Just another way to rip us tax payers of

yachal.upson says:

The future probably lies in compact residential hubs ('Villages') inland, as seen in Europe - where planning protects farmland and nature, and improves access; to services, recreation, high value jobs

8 October, 2021

yachal.upson says:

To protect high value jobs, and to align with urban development choices, planning and zoning decisions need to be made urgently; to provide smart commercial space in areas such as the Moutere Hills

8 October, 2021

yachal.upson says:

Current commercial and industrial development zones in Mapua, Lower Queen Street Richmond (and even to an extent in Motueka) are at high risk within the century; an irresponsible choice for the future

8 October, 2021

yachal.upson says:

Coastal zones are at risk; and reducing travel is critical to curb climate change impacts. Moving our community to safe areas must be accompanied by relocation and co-location of jobs inland.
