Committee considers tidal barrier feedback

Committee considers tidal barrier feedback

Large scale investigations into a tidal barrier on the Avon-Heathcote Estuary may not go ahead following a Christchurch City Council committee recommendation today.

Mixed feedback from strategic partners and key organisations was considered at today's meeting of the Council's Infrastructure, Transport and Environment Committee, as councillors recommended against proceeding to the full feasibility assessment stage for a tidal barrier.

The Council has been in the early stages of exploring a potential tidal barrier as one possible option for reducing the flood risk in low-lying parts of south-east Christchurch. Some parts of Christchurch dropped during the Canterbury Earthquakes and some of these areas are now more vulnerable to flooding. As well as addressing this increase in flood risk a tidal barrier would also help protect the city from sea level rise for now but not forever.

A pre-feasibility study was commissioned to help the Council and Crown funding partners understand if a tidal barrier was technically feasible and to provide a ballpark idea of the cost. The study found a tidal barrier was technically possible, but would cost up to $350 million to build, have major impact on the estuary environment and not remove the need for other additional defences against flooding.

Committee Chairman Phil Clearwater says, "Overall, stakeholders did not strongly support the tidal barrier project and the committee believed a better approach was to look at the full range of alternative solutions as part of a city-wide flood management strategy. We need to act responsibly by considering the best interests of the whole city. The tidal barrier is not a 'silver bullet' for solving flooding issues."

The Council is expected to make a decision at its next meeting on Thursday 29 October 2015.

Gordon Campbell: On How Climate Change Threatens Cricket‘s Future

Well that didn’t last long, did it? Mere days after taking on what he called the “awesome responsibility” of being Prime Minister, Christopher Luxon has started blaming everyone else and complaining that he's inherited “economic vandalism on an unprecedented scale” - which is how most of us would describe his own coalition agreements, 100-Day Plan, and backdated $3 billion handout to landlords...

Public Housing Futures: Christmas Comes Early For Landlords

New CTU analysis of the National & ACT coalition agreement has shown the cost of returning interest deductibility to landlords is an extra $900M on top of National’s original proposal. This is because it is going to be implemented earlier and faster, including retrospective rebates from April 2023. More

Green Party: Petition To Save Oil & Gas Ban

“The new Government’s plan to expand oil and gas exploration is as dangerous as it is unscientific. Whatever you think about the new government, there is simply no mandate to trash the climate. We need to come together to stop them,” says James Shaw. More

PSA: MFAT Must Reverse Decision To Remove Te Reo

MFAT's decision to remove te reo from correspondence before new Ministers are sworn in risks undermining the important progress the public sector has made in honouring te Tiriti. "We are very disappointed in what is a backward decision - it simply seems to be a Ministry bowing to the racist rhetoric we heard on the election campaign trail," says Marcia Puru. More
