damaged infrastructure

When Cyclone Bola went through the East Coast the feeling at the time was that this was a once in a lifetime event and ’we’ wouldn’t see anything like it again. The events of the last week or so have put paid to that, if Cyclone Hale the previous month didn’t.

An observation though (from afar) whereas the rainfall in Bola in the back of the Gisborne region was 900-100mls over the 48 hour period. This event was nearer half that.

Given the damage from Cyclone Gabrielle has matched or exceeded Bola I’m wondering what is different.

One thought is that it has occurred closer to the coast, thereby having a greater impact there? Although the Hikuwai River at the 5 bridges (SH35 between Tolaga Bay and Tokomaru Bay) was clearly higher than in Bola and that was water largely coming from the back country (I haven’t seen Waipoa River details yet).

Was it the forestry slash continuing to impact? The HMNZS Manawanui couldn’t unload aid at Tolaga Bay wharf due to the amount of forestry slash in the bay and visuals on television in many areas show large amounts on river banks against bridges and elsewhere. The question now comes to what lessons come from this (some we seem to have forgotten from Bola et al).

Living near a main centre while the lack of communication is a frustration it is not a life and death issue (mostly, will come to this later). When I lived in the Gisborne hinterland and from memory in the Manawatu ‘we’ had Civil Defence points dotted along the main highways. As were First Aid points. These were at mostly farm houses where some basic supplies were kept for emergencies and access to a land line phone. It appears these seem to have been done away with (I haven’t had to venture too far off the main highway of late so could be wrong).

If I am correct these obviously need to be reinstated and upgraded.

Given current technology there is no excuse for at least some emergency power to be available to run satellite communications. Between solar power and a small generator, satellite technology (at a price) is available to all now.

For these CD centres this should be standard issue and available to the local community in times such as these, funded from central and/or local government. The fact that whole areas had zero means to communicate with the outside world seems almost laughable if it wasn’t so tragic. An aside here which also I think our recent fire highlighted, Messenger an internet based ‘phone’ system which doesn’t rely on cell towers does not appear to be used by the emergency services. Hopefully something else to be rectified.

Without a communication network nothing else can occur in a rational manner and help will be ad hoc and not hitting the right areas.

Some of these processes will not even cost much to setup. Both national and regional government once they have the population safe now have to turn their heads to what the next steps are.

As a nation we have been heavily focused on climate change mitigation. It is now too late for any short term gains so the focus now is adaption, or as I heard one say, “managed retreat”. The mood seems to be that this is something that needs to take place slowly and carefully due to its complexity. Unfortunately, for those living in both remote and not so remote, pondering on the question would come as cold comfort. Three major events in the last twelve months means that action is going to have to happen fast. One thing the Labour government has shown is that it can make hard and fast decisions around critical occurrences. The Christchurch earthquakes, which were led by both National and Labour, also provide somewhat of a blueprint which can be utilised.

The response to climate events will be more complicated due to the widespread nature of its impacts and multifaceted nature. I do wonder if the last few weeks maybe months has put much of the criticism around 3 Waters to bed. Labour certainly can be criticised for how the process was rolled out but the need for more centralised planning and funding has become obvious. Unfortunately, this now extends beyond water to roading, communications and maybe health with a decent dollop of the RMA included in there.

I was certainly among those, who unconsciously, were vaguely conceited about the climate change impacts upon New Zealand. We seemed to be escaping the worse effects seen around the globe and in some areas might even benefit from it. However, when seeing how badly damaged even Hawkes Bay has been (taking nothing away from Northland, Coromandel and Tairawhiti but we already knew they were vulnerable and of course the Auckland urban and rural areas also were heavily impacted) then nowhere is safe.

Christchurch which has had a charmed run since the 2010-11 earthquakes is bounded by the (large) Waimakariri River on one side and the Selwyn and Rakaia rivers are not too far away on the other plus the Avon and Heathcote River, while short run rivers, can also rise appreciably through the middle of the city. No doubt almost every other town and city has a similar scenario where there has been extensive works put in over the years but now, we are having to reassess.

If the previous year's weather events hadn’t forced a major focus on future planning by government, then surely Cyclone Gabrielle has.

The short runup to the next elections may further muddy the waters unless some bi-partisan discussions can take place. If the politicians go ‘political’ and try to ring fence their own party’s policies then I can see a good reason to call for an early election. This will allow whoever is in power to have a three-year term ahead to plan without the distractions of a dragged-out election. This tends to be not the New Zealand way and hopefully avoided, but we seem to be going into extraordinary times. What ever happens there needs to be some longer term planning around both the funding and creation of critical infrastructure, and it needs to be occurring now.

OK, I've worked out a plan.  To get away from coastal devastation and rising seas we will retreat to the volcanic plateau and rebuild there.  Waiuru will be the capital. 

Of course, it's a volcanic plateau...

We could consider terra forming our low lands and building higher plateau's to construct towns upon, then redirect water flows into enlarged river systems(what we take from the river we give to the plateau) around them. If the Saudi's and Chinese can do it why can't we?!  It's definitely somewhere to put all that newly available silt that has nowhere else to go.

An excellent article, thanks Guy.

Porirua City Council has already approved a managed retreat policy with respect to frequently flooded properties;

The full report to council can be found at this link within the article;

Council officers said Wellington Water identified 44 houses at risk of internal flooding above floor level in a once-in-a-20-year event. An on-site inspection would be needed for confirmation.

Point is - this provides an excellent existing example of how local government can act now - in advance of central government decisions on the Climate Adaptation Bill which is not expected to be introduced to Parliament until the end of this year.

Local authorities CAN act now - a blueprint for good planning management exists - no excuses.

An interesting document. Key issues, funding and voluntary participation in the scheme. Porirua specifically is a poor council having perhaps misspent its revenue and also unable to borrow sufficient funds for capex/ renewal projects. One of the first to jump onto 3 waters. You don't need to have 3 waters to help a council such as Porirua. This can't be a voluntary scheme.

To be dicky opposite - let the owners leave of their own volition if the properties flood again and they can't get insurance. I can bet your bottom dollar they won't want to contribute a cent to any move or work to raise their houses.

Another aspect to evaluate. Which are rental properties and which are owner owned and lived in. For me that is fundamental in any financial assistance, whether from council or central govt.

What I don't get is if nothing is done how does that impact to other ratepayers. Perhaps sewage, water and storm water services are so badly impacted by flooding that it costs the council an arm and a leg to repair.

Furthermore evaluating flood plain levels is already done by most councils. They may need updating.

Glad you found it interesting. To my mind, voluntary is the only way to go in the immediate stages of implementation of managed retreat. And only those buildings that meet a set of criteria determined by the council are able to volunteer to participate in the scheme.  The council will have set those criteria based on its own knowledge of infrastructure upgrade needed to prevent flooding.  Basically, those properties that are beyond being able to have flooding (at existing floor levels) mitigated going forward.

No need to worry about funding - central government will be paying the lion's share unless the debt ceilings of local government are re-set via the LGFA.  If we don't borrow to build resilience now, there won't be the option in the future - global resources (oil, minerals, timber etc.) will become too scarce (as will global finance).

Can't delay the inevitable - these things just have to be done unless we want homelessness to go through the roof in future.  Don't know if you've been to the larger cities in the States recently, but I really don't want to see tent cities springing up in the middle of roundabouts and lining every bit of grass verge available.

Yes, council's are constantly updating flood maps - and we're going to need to implement a whole lot of no-build (no re-build) zones across the nation.

And the govt should place an immediate order for thousands of these (or like);

https://www.trademe.co.nz/a/motors/caravans-motorhomes/caravans/more-than-24-ft/listing/3983079228

Scour the country for all existing ones and buy them - and then get a bulk order, simple design standard out to industry immediately so they can personnel and tool up to bulk manufacture the rest needed.

We don't really need to count the numbers - we know that thousands of people will not/should not return to their previous homes/accommodation ever.

Build these tiny neighbourhoods away from future harm and let people get on with having a dry, safe, healthy place they can call home asap.

This well-built Chinese tiny house has everything one could wish for in a tiny house.

It'd be double that price for a decent one made here, which is very expensive per square metre of living area.

Concept overall is good, but just make 50-120m2 prefab houses. Transport to site and put them on piles.

Yeah, I saw that was originally made in China nad had to be spec-ed up for NZ regs. Was just using it as an example of an existing one on the market - and there are perhaps a hundred different ones on TM that could be purchased immediately.

My thought is it might be better to go tiny house on wheels (as opposed to perm homes on piles) for ease of relocating to the next disaster or the next emergency accommodation site/town..  Release a standard design spec and let the engineering firms and the tiny house builders get building to that standard spec - purchase guaranteed by government up to a certain number per supplier.

The tiny houses remain government assets - as they are used just for emergency purposes whilst insurance claims get worked through.

People/families that are homeless now are going to face a long haul before such time as they re-build permanent lives.

You can import used English or American caravans for 30 -50000. they have everything you need in hem . I was saying for the last few years this is the solution for the emergency housing crisis. 

I think the reason they haven't is the political backlash from putting people in caravans and "Trailer Parks" , never mind that people choose to live in these , and those that don't will be better off than sleeping in a car.

Great idea.  I’d just suggest use of solar panels for some electricity (including water heating), in case of power or gas unavailability, and of course to avoid GHG emissions which are root cause of the problems. A few specific adaptions could be made so they become as fit for purpose as practical

Quite shocked the cell phone towers don't have backup batteries and /or generator. Solar and wind would be a sustainable addition. Plus a line of sight or radio backup system to ensure basic data at least can get through . 

From what i understand , early cell phone towers had backup power , but the high data use of 4 and 5 g etc makes it more difficult.

And in the old days we had many, many amateur/hobbyist radio operators.  That's the hole that plugged many an emergency comms gap in disasters in earlier days.

Should be part of standard safety/emergency kits for all rural property owners IMO.

Almost certain they do but it'll only last a few hrs, probably < 8. Too expensive otherwise to put in for a longer duration. There'll be little room on the pole for a solar array or a wind turbine. Nice idea on paper but major financial, consent and technical issues to implement. It would have to be forced on the cellphone providers.

Another thing that came to light was the cycle trails provided an alternative way out in some places , where the road was blocked. I met a couple walking it to get to a hospital appointment , and some volunteers clearing fallen trees by hand . I used it to go see my lifestyle block , albeit across the river , at least i could see stock were not near the river.

Another point about the worst hit areas - we need to be flying people out - not food and water in.

This mud and silt is contaminated; garbage and garden waste will become contaminated - they haven't got the capacity needed in landfills and there is no sense in cleaning out a house that will never be habitable again.

https://www.stuff.co.nz/national/300810621/cyclone-gabrielle-if-youre-cleaning-up-dont-abuse-dump-staff-theyre-traumatised-too

Fly people out - nationwide billeting register needed urgently.  We've got spare room for a family of 4-5.  We should be able to put our name and address on a register.

Funny how the news media 'gets it' earlier than the government;

https://www.stuff.co.nz/national/300810677/cyclone-gabrielle-what-life-is-like-in-a-disaster-zone

I watch folks living in this disaster zone pleading over the live media reports - 'don't forget about us' - meaning we're here and hurting. They should be asked, would you rather stay with this hardship for the unforeseeable future, or would you rather leave now?

That would be interesting.

Families I knew in Chch got there kids out of there asap.

Kate people in affected communites should be asked what help they need, not told they have to leave their homes/land etc and leave it to who to clean up?? As to a register - you can contact the mayoral fund/rural trust/civil defence/Red Cross to lodge your offer of accommodation, if you haven't already.  One of these will manage accommodation offers.

Nobody wants their property tagged as being in a flood zone, yet how many do their due diligence when purchasing a property. Infrastructure can only mitigate so much and requires cyclic maintenance. How long is it before everybody forgets the flooding or earthquake vulnerability?  How often do we see land being altered to cater to housing when ideally such projects should be occurring elsewhere ( swamplands /coastal and slip prone areas etc) Engineering is capable of many miracles but has its limitations (costs/design flaws/overload etc etc) How many councils work on a reactive model rather than a preventative model ? How many councils have alternative routes/back up water power ability available that ensure disruption is minimalised in times of an accident or event? Plenty to consider but all will be a distant memory I suspect until the next major event....

Exactly. We will move onto the next crisis and this one is forgotton.

The fastest way to resolve it is to make nz home and contents insurance compulsory (in the uk car insurance is compulsory). To include some form of emergency accomodation payment for a major event.

Sure insurance  would get very expensive.. but going forward  those that live in areas prone to weather events would pay (through insurance) for the priviledge. If people choose to live in safer locations they pay less.

It shouldnt require government intervention or money. Aside from requiring the insurance industry to have written funded plans to relocate and fund a large number of people in the event of a disaster.

"It shouldnt require government intervention or money"

It absolutely will require government intervention to stop piss-taking blocking of development in areas by well-heeled residents. Otherwise you are simply advocating for a tax on those who can't afford to move out of flood plains or away from flood risk, which would then be priced considerably higher as a result.

We should not underestimate the power of this event plus that we had other large ones just a few weeks earlier, these do accumulate in weakening infrastructure. 

There's no easy answer. Many of the risk areas have been identified for decades but people persist in wanting to build and live there and conduct certain landuses.

River valleys are FLOOD Plains. Hint!!

Stop banks simply mask the risk until they build up and overflow thereby releasing years of what would have been smaller events into 1 massive one. CHCH one day will have the Waimak go through some of it - all the modelling has been done.

Can we compensate everyone? Should we do it?

After this if anyone rebuilds in these flood areas you have to question our sanity. I know it's all the land they own but what and how we do this is vvv hard.

We can't run from everything but do need to get a lot better at risk assessment and use the results.

What I suspect we will have to do is designate a lot of no-build and no-re-build zones - and yes, compensate.  Already we have EQC that will cover a land component up to a certain amount. I suspect there is a lot of government-owned land (e.g.,https://pamunewzealand.com/) that can be urgently sub-divided where section prices can be offered to displaced land owners at the level of the EQC payout - hence, displaced homeowners only have to find the dwelling re-build cost via their insurers.

If they want to build in these flood prone areas,( and there are alot of emotional and cultural reasons why many would), then they should raise the house to the 2nd storey, and have a garage underneath, using h4 timber, and h5 poles.

Yes, look around Brisbane. The old Queenslander houses are built on high poles to counter what used to be regular floods. Yes homeowners have done downstairs extensions over recent decades, but the original principal stands. Florida also copes with their regular disasters not by abandoning the state, but by mandating new housing be robust to withstand strong hurricanes (much stronger than Gabrielle).

It's not all or nothing, we just need smarter building codes in each area.

Christchurch is a different,already making the decision to remove land use on flood prone areas,following the earthquakes where an upraised water table accentuated risk across parts of the red zone.Other flood prone areas such as the Flockton basin (which had a long history of flooding) saw mandatory purchases,creek widening and deepening,additional pump houses and catchment ponds.

Large catchments are already completed since the quakes,will total 2 m m^3 when complete and allow slow return of excess water to rivers at low flow.The next works are opening parts of the meandering loops on the Avon into the redzone, and returning to wetland (this will be by removing stop banks).

The other large braided rivers,need better management of removal of deutris and spoil routinely at points around bridges and loops,deepening of some parts to allow the flush properties of the rivers to work.

I agree with the CCC.  Two waters - reticulated services only if indeed centralisation/consolidation in respect of drinking and wastewater can be proven to be more efficient.  Stormwater and flood protection need to be locally managed - in concert with local determinations regarding no-build zones and managed retreat.
