Feedback wanted on downstream flood options

Christchurch City Council wants feedback from residents in the Dudley Creek area and the wider community on three proposed options for downstream, long-term remediation work on Dudley Creek.

The work aims to return the Flockton area to its pre-earthquake level of flood risk. Consultation opens today and feedback must be received by 5pm on Wednesday 8 July.

The proposed options being consulted on are:

• Option A – Warden Street, Shirley Intermediate School piped bypass and localised Banks Avenue channel works.

• Option B – Warden Street, Shirley Intermediate School, Marian College, Richmond Park and Residential Red Zone (or Medway Street) piped bypass.

• Option C – Localised Stapletons Road channel works and piped bypass in Petrie Street, Randall Street and Medway Street.

Following the close of consultation the project team will use community feedback, along with further technical advice and a Multi Criteria Analysis (MCA), to identify a preferred option. This recommendation will then go to the Council meeting on 13 August 2015 for elected members to decide which option will progress through to detailed design and construction.

Director Council Facilities and Infrastructure, David Adamson, says this is an important project for both the Council and the people living in the Flockton / Dudley Creek area.

“These downstream works, wherever they are carried out, will provide a well-balanced and well-designed option for improved flood defence for the community. Work is expected to take two years to complete and will be delivered by mid-2017.”

The Council initially consulted with the community in November 2014 on its then-preferred option for Dudley Creek long-term flood remediation. This option proposed widening and deepening Dudley Creek along Banks Avenue between the Avon River and North Parade to increase the waterway’s capacity.

Community feedback from the November consultation and technical advice formed a report back to Council in December 2014, with elected members resolving to progress the Dudley Creek works in two sections – upstream work (areas approximately west of Stapletons Road) and downstream work. They also requested a more detailed comparison of the downstream options, which are the subject of this consultation.

Options A and B vary significantly from the initial designs that were reported to Council in December 2014. This is in response to community feedback and more specific and detailed assessment, surveying and design work. Option C was not part of the November 2014 consultation, but is now being considered following further assessment.

The consultation booklet is available to view in any of the Council’s libraries and service centres. It is also available online at www.ccc.govt.nz/haveyoursay. The final date for written comments is 5pm on Wednesday 8 July 2015.
