About the Pōrangahau project

The solutions being considered and developed include a stopbank and the raising of some properties. This work will ensure that Pōrangahau’s Category 2A properties can move to Category 2C, followed by a move to Category 1.

Latest update - October 2024

This month, our project team has been continuing discussions with directly impacted landowners and the wider community to present the updated proposed solution and alignment, and capture feedback. We had a great drop-in day earlier this month at the Pōrangahau War Memorial Hall where we talked to many different people about the project.

We have been working to progress the proposed design concept towards preliminary design. This has involved us looking at the engineering options for the areas of flood wall, assessing erosion protection needs along the banks where the proposed solution lies, and capturing directly impacted landowner feedback. The next step for progressing the design is to begin site investigations. We are planning for these to begin before Christmas, depending on contractor availability. These investigations will include geotechnical, ecology, archaeology, and contaminated land assessments.

We continue to collaborate with Central Hawke’s Bay District Council to ensure that the proposed design allows for their current stormwater networks and any future plans. Over the next month, we will work to update the flood models with and without the solution in different weather events to share. We are also identifying possible borrow sites for material we can use to construct the stopbank. Borrow sites are places from which we excavate material for construction and which are then backfilled post-work.
