Damaging Storm Costs Waimakariri Council Nearly $1m
Speaking at a council meeting on Tuesday, July 1, the council's utilities and roading general manager Gerard Cleary said the investment of more than $20m in drainage improvements in Kaiapoi in recent years has paid off.
Heavy rain swept through Canterbury between April 29 and May 2, causing flooding in Christchurch and Selwyn.
In Waimakariri, there was damage to roading and three waters infrastructure, resulting in 49 services request and a repair bill of $972,953.
''This event really showed the benefit of some of the investment the council has made,'' Mr Cleary said.
''In previous events such as 2014 we saw substantial surface flooding in parts of Kaiapoi.''
The extra drainage capacity also relieved pressure from excess water getting into the sewer network, he said.
Mr Cleary said around half of the nearly $1m of emergency works is being funded from existing budgets.
With the majority of the expense for road repairs, the council has applied to Waka Kotahi NZ Transport Agency for emergency works funding.
The Christchurch and Selwyn councils declared local states of emergency following the flooding, but Waimakariri Mayor Dan Gordon said his council's infrastructure investment had made the district more resilient.
''When nature comes along we are bound to respond. It is what our community expects and we need to keep our community safe and protected.
''We were close to a declaration, but because of the work which had been done and the updates we received from Environment Canterbury, we felt we didn't need to.
''These aren't one off events and they are occurring more often than we would like so we need to keep on top of it.''
The council's investment from the 2024/34 Long Term Plan in an infrastructure resilience team also meant the district was prepared, he said.
Mr Gordon said more work is planned to improve the district's resilience to future flooding, including for the Mandeville area.
''In our capital budgets for future years there is quite substantial money set aside for drainage projects and I know that the Mandeville drainage project, which I know councillor [Paul] Williams has been pushing for, would mean about $22m in debt if we choose to go to stage two.''
Mr Cleary said even with taking on extra debt to fund further infrastructure investment, the council would be able to respond to a future earthquake or major flood event.
He said the council has insurance to cover its three waters infrastructure in a major event, and it can apply for NZTA emergency works funding, alongside debt funding.

As the sea level rises, who will pay? Councils seek answers

Photo: Supplied / Waimakariri District Council North Canterbury's councils want to know who pays for preparing for climate change as major storms and flooding threatens local communities. Local Government New Zealand (LGNZ) has warned a lack of clarity over who pays for measures to protect communities from sea level rise, flooding and weather events could leave ratepayers with a hefty bill. The concern follows the release of a report from the Ministry for the Environment's Independent Reference Group on Climate Adaptation, which raises the question of who should pay. Environment Canterbury is planning to review the Kaikōura flood protection scheme on the Kowhai River. Photo: Supplied / Environment Canterbury Waimakariri District Council chief executive Jeff Millward said his council is beginning work on a climate adaptation strategy as it looks to prepare for the threat of sea level rise and the growing number of severe weather events. For earthquakes and flooding events, the council has insurance through the local authority protection plan, which covers 40 percent and the balance coming from Government or loan funding. But preparing for sea level rise and flood mitigation measures costs money, Mr Millward said. As the risks become more severe, there may be changes to what insurance is available, or even ''no insurance at all''. ''Does it fall back on the ratepayer or the taxpayer? It is a bit more complicated and a lot more discussion has to happen.'' Councils already have clauses in District Plans identifying natural hazards and impose regulations such as minimum distances from the waterline and raising floor levels to 1.5 metres off the ground. ''People like living near the beaches or rivers, but it puts those properties at risk, so there is going to be a lot of modelling work done to identify the risks and develop and array of tools,'' Millward said. Environment Canterbury has working of flood protection across the region, works on the Waimakariri and Kaiapoi Rivers to protect Christchurch and Kaiapoi. Photo: Supplied / Environment Canterbury Kaikōura District Council chief executive Will Doughty said the region's councils are working on adaptation plans, following the launch of the Canterbury Climate Partnership Plan by the Canterbury Mayoral Forum in December. ''One thing is for sure - there is going to be a bill. I think we do need clarity and it is a conversation we need to have. ''I think the steps Canterbury has taken as a region to put that action plan in place has put us in a good position. ''It's a much bigger issue than any one particular district and the more joint action we can be doing the better.'' Kaikōura's pristine coastline faces threats from the sea, despite a coastal uplift following the 7.8 magnitude in 2016. Photo: David Hill / North Canterbury News The recent report warned it may not be sustainable for government buy-outs to continue for properties in at risk areas, with weather events such as those facing the Nelson region expected to become yearly events in some areas. It recommends phasing out those buy-outs over a 20 year period. Adaptation measures, such as flood schemes, sea walls and infrastructure, should be funded by those who benefit, the report advised. On Monday, Prime Minister Christopher Luxon told RNZ the government will not be able to keep bailing out homeowners after major floods . The Hurunui District Council has completed climate adaptation plans in partnership with its beach communities. It has led to the council buying a $3.8m block of land south of Amberley to prepare for future events. Residents from at-risk communities will be able to secure sections by paying a targeted rate over the next 30 years. The plot of land would be attached to their existing property, so the two properties cannot be sold separately. When the time comes, residents could transport their house to the new section, or build onsite. A new bund is providing some protection to Amberley Beach residents for now. Photo: David Hill / North Canterbury News Council chief executive Hamish Dobbie the issue is complex and councils need some guidance from government. ''Some guidance suggests we should be involved at all. We should only be involved in roads and pipes. ''There needs to be a good sensible conversation about this.'' LGNZ vice president Campbell Barry said the ministry's report has failed to address some concerns previously raised by local government. ''It's good to see the report's sense of urgency. Our submission on climate adaptation in June last year stressed that action is needed now. ''We need to have better policies and frameworks in place to cater for increasingly severe and frequent weather events. ''Local government can't afford to have another Cyclone Gabrielle. The aftermath of a significant weather event like that comes with massive financial, infrastructure and human costs for communities.'' Barry said the lack of clarity meant the burden of paying for adaptation was likely to fall on ratepayers. Luxon said Climate Change Minister Simon Watts had been working to get a bipartisan view on how to deal long term with major weather events. - LDR is local body journalism co-funded by RNZ and NZ On Air.

Damaging Storm Costs Waimakariri Council Nearly $1m
Severe weather and rain which hit Canterbury in May cost Waimakariri District Council nearly $1m in emergency works, but council staff say it could have been a lot worse.

Flooding processes defended
Selwyn District Council and Environment Canterbury have defended how they responded to the major flooding in the district early last month. Mayor Sam Broughton and Environment Canterbury chair Craig Pauling have told Emergency Management Minister Mark Mitchell the flooding infrastructure held up, and the processes to manage flooding were up to standard. They were responding to a letter from Mitchell sent to councils across New Zealand asking them to have a 'frank and honest' discussion about responding to flooding. In his letter he highlighted the flooding in Canterbury, where parts of Selwyn and Banks Peninsula were hit hard. "No stopbanks were breached or overtopped, and although drainage schemes were overwhelmed in places, they behaved as expected with water entering known ponding areas,' Broughton and Pauling said in a letter sent to Mitchell. The district saw two months of rainfall fall in about 48 hours, causing a large amount of flooding, particularly around Ellesmere and Tai Tapu. A particular concern among the community was whether Te Waihora/Lake Ellesmere could have been opened ahead of the flooding to reduce the impact. Broughton and Pauling told Mitchell even if the lake could have been opened, it would likely have made little difference. 'Unfortunately, sea conditions prior to the event were not favourable, and any opening attempt would have been unsafe and unsuccessful. Had an opening attempt been made a week earlier, it would have closed quickly and likely would have had little effect on water levels during the event.' It was noted in the letter that ECan wants the Government to continue to assist with funding for telemetry to monitor river levels and flows. "To further support upgrades and strengthen resilience, co-funding with central Government has been sought within the Regional Infrastructure Fund to further accelerate our work.' As part of its continued review of the May floods, the district council is paying particular attention to Doyleston, which was one of the worst-hit areas in the district. On Sunday, council staff met with Doyleston residents to get local knowledge of locations that may have contributed to the flooding. Staff said it would use that information to establish the next steps for the settlement.
