Waiohine River Floodplain Management Plan

Waiohine River Floodplain Management Plan

Updated 19 January 2018 10:35am

What you told us

The draft Waiohine Floodplain Management Plan (FMP) was released for public consultation in June/July 2016 . 107 submissions were received, on behalf of both individuals and groups. A majority of submissions opposed the draft FMP on one or more grounds. The planned hearing of these submissions was cancelled.

What now

Following consultation with Carterton District Council and South Wairarapa District Council, in August 2017 GWRC revoked the draft FMP and decided to reengage with the community through a community-led process. The aim of this process is to produce a FMP that enjoys the support of the community and is affordable, pragmatic and sustainable.

Currently, the team is focussing on reviewing and updating the flood maps, along with the background information and assumptions that they are based on. The flood maps are important because they underlie many of the other subjects and decisions. They were also something that many people in the community are concerned about and made submissions on previously.

This work is being done in collaboration with the Waiohine Action Group (WAG), which is composed of members of the local community with an interest in the FMP and expertise that includes local government, management and operational work in the Waiohine River, engineering, hydrology, surveying and business/project management.

How can I get involved?

If you provided a submission on the previous draft FMP this has been fed into this new process.

As well as having opportunities to contribute to the new draft FMP informally as it’s developed, you will also be able to provide feedback on the new draft FMP once it’s ready. All previous submitters will be contacted again at this point.

Tell us what you think

The current work is being done through a very open and inclusive process. Anyone is able to ask a question or make a contribution at any time. Following each Project Team meeting, the notes from the meeting and a summary are posted on the WAG Facebook Page and emailed to the WAG email list.

You can contribute at any point – questions or comments are welcome – by using the feedback link on the right or by contacting any member of the project team. WAG also coordinates a number of events such as public meetings. These will be announced through the Facebook page, the WAG email list and advertised locally. To have yourself added to the email list, please contact
