EQC releases Christchurch flood model progress

The timetable for the Earthquake Commission’s flood plain modelling of Christchurch has been pushed out to May.

The information was provided to NBR after a request about progress late last week.

The flood modelling was initiated in June 2013 with an expected completion date of March.

The purpose is to determine the best flood remediation and specific foundation repairs for directly affected properties.

EQC estimates there are 309 homes in this Increased Flooding Vulnerability category and their earthquake repairs have been placed on hold.

Many more homes may be identified after yesterday's floods.

EQC says it has contacted the 309 homeowners and reassessed their properties.

“EQC will also offer them a choice about whether they would like to have their property repaired through the repair programme ahead of the confirmation of their land damage; receive a cash settlement and manage their own repairs; or remain on hold within the CHRP programme until such time as their land damage has been confirmed and they can make a more informed choice,” EQC says in a media statement.

However, many questions remain such as the total number of properties now at risk of regular flooding, if more areas will be red zoned or protected, and if large number of homes have been inadequately repaired already.

The city has dropped on average about 20cm with some areas more and less.

Even within the most flood prone areas there are some earthquake-damaged properties that are high and dry but they are caught up in repair delays because of the Increased Flooding Vulnerability category.

Today the floods have subsided in most places and sunny weather has returned.

Earthquake Recovery minister Gerry Brownlee and Mayor Lianne Dalziel toured flood affected areas.

In Parliament yesterday Mr Brownlee apologised for his attacks on Labour MPs the day before.

He says EQC misled him about the number of vulnerable elderly people still awaiting decisions about their earthquake-damaged properties.

EQC had told him there were just five cases but it transpires there were at least 85 cases that had been officially brought to the attention of EQC.

Comments and questions

I was in CHCH yesterday and the day before and the PR spin coming from there that this was a 1 in 100 year event is a load of bollocks.

The only real flooding was around the Avon and Heathcote rivers and the rest was a result of broken infrastructure that hasn't been fixed.

The amount of rain they had was an average rainfall in Auckland

The flooding was in low lying areas where the broken infrastructure couldn't cope.

No point blaming the Government - blame nature and the time and cost it takes to 'put it right'

The psyche in CHCH is tender still and they are all vulnerable to still blaming everyone for their problems caused by nature.

It will take time to fix and they should be more grateful for what the NZ taxpayer is already doing for them

What has the average rainfall in another part of the country with a completely different climate got to do with it?
Also to blame nature is a tad unfair. OK there have been earthquakes, but as far as I am aware no one was shook to death. The problems are the result of unsatisfactory building designs & the problems are now being compounded by the speed of the rebuild.
The last time I checked Christchurch residents were NZ taxpayers btw

You might want to check your average rainfall data rather than just trying to wind people up. This was not a normal event.

Not totally correct - the fact the land has subsided by up to half a metre in some of the affected areas is a major contributor. What EQC et al decide to do about that (Red Zone it, develop design rules for repairs/rebuilds, etc) is what most people want to know, as the flooding is now an annual event post quakes - storm intensity/duration now determines how deep the resulting flood waters will be.

Agree this was not a 1 in 100 year event - I've seen much heavier and longer duration storms!

The Doctor can relax about us being "grateful about what the NZ taxpayer is already doing for them" because Key's keeping VERY quiet on the fact that the bill is a paltry $3 billion (NBR please do an OIA on Treasury re all of this). Taxpayers are only tipping in $15 billion yet the fiscal take from the rebuild is $12 billion (due mostly to all those billions coming in from offshore reinsurance). You can also deduct $300 million because Cantabs are 10% of NZ's population. I suspect $2.7 billion is the equivalent of a couple of Auckland motorways??

Should the headline not read 'EQC releases Christchurch flood model lack of progress' ?

In the same length of time that has elapsed since the deadly Christchurch earthquake in Feb 2011 ( a span of 3 years) the US had gone from been attacked at Pearl Harbour, conquered in the Philippines and very nearly wiped from the Pacific altogether to having put ~12 million men and women under arms, mounted the largest ever seaborne invasion in history, of Europe, and had begun the bombing of the Japanese mainland from islands wrested from Japanese control, and all with the limitations of1940s technology, some of which they had to invent.

Meanwhile in Chch, the EQC can't even figure out what part of a fairly small city will flood, by how much, and what to do about. And even with all the extraordinary technology that is available to us today. Pathetic. One can only draw the conclusion that they are stocked with incompetent 3rd raters who are immeasurably stubborn to boot.

Thank God it wasn't people of the calibre of the EQC who fought WWII or else we really would be speaking Japanese or German.

I mean just where is the sense of urgency here?

You cannot compare a world war with an earthquake. Millions of lives were at risk. The people of Christchurch are lucky there is such a thing as the EQC!

Might help if they dug out the rivers seeing as the earthquake filled them in somewhat.

Time to stop insuring land.
