We are making good progress on options for reducing flood risk in the Karehana catchment, but to make sure we put the best possible information in front of Porirua City Council, we have had to push the timeline out a few weeks.

Karehana catchment long term options – new dates

We are making good progress on options for reducing flood risk in the Karehana catchment, but to make sure we put the best possible information in front of Porirua City Council, we have had to push the timeline out a few weeks.

The Council is now scheduled to make decisions on 7 October 2021.

We know the community is keen to see rapid progress, and this extension of the timeline will be frustrating, but it is important that we get this right. 

There are two main reasons for the extra time.

  • Due to the many factors contributing to flooding, the engineers are putting together packages of infrastructure options. It is taking time to fully assess the impact, effectiveness, risks and costs of a number of different combinations of options.
  • The Council wants to know what the community thinks of the options before it makes its decisions.  This means finding time for you to consider and provide feedback on these.

The Plimmerton Flood Management and Resilience Working Group has been providing the Project Team with a valuable community perspective on the flooding hazards and the options to date, and will consider the options and be invited to provide feedback to Councillors.

We also want to give everyone in the community the opportunity to have a say. We will be providing information about the options online and at a drop-in session and inviting you to provide written feedback.

The timetable is:

  • 2 September: Options presented to a Council workshop, and to Flood Working Group members
  • 3 September: Options made public on Plimmerton Stormwater website and advisory email sent out
  • 8 September (4 pm – 6.30 pm, Plimmerton Pavilion): Drop-in session where you can ask questions about the options
  • 20 September: Feedback on options closes
  • 23 September: Councillors consider written feedback and hear from Flood Working Group
  • 7 October: Council makes decisions

We will send an email to the community on 3 September about the options and inviting your comments.
