We want to extend our Mount Albert home by extending into a nearby 100-year flood plain. Any extension would be well above the maximum flood level (at least 1m). Has anyone had any experience building into a flood plain and how flexible Auckland Council is on such issues.

Originally posted by CraigD View PostThanks for that, I'm guessing that your 1.4m is above ground level as opposed to above predicted 100-yr flood level? Did you have to sink your piles down over 4m and get a geotechnical report prior to?
Not sure how deep the piles go.
Yes to geotec.

CraigD, we did this years ago. UP on our section which was around 3m above road level lol.
Basically we just had to get an engineer to stipulate how deep the water might be. So he wrote a report which we used for our design.
As long as the council's arse is covered, it's all good.Squadly dinky do!

Christchurch's waterlogged homeowners are facing a triple whammy - damage caused by the earthquakes and floods could cause a big drop in property values.
The city's property valuers and real estate agents are calling for fast action to prevent whole neighbourhoods becoming unsaleable.
One city lawyer had a real estate sale "crash" yesterday after an insurer refused to cover a client about to buy a house in the Flockton Basin.
"We expect to see more to fall over, this has got big implications," said the lawyer, who declined to be identified.
She warned that the "woolly" references in council LIM reports to flood plans were no longer specific enough.
Property valuer Natalie Edwards said the situation was "daunting and scary" for any owners wanting to sell homes after on-going flooding.
"You'd have to make it so damn cheap to make it attractive.
Without any council remediation or plans, they are stuck.
Nobody is to going to buy there - why would you?"
Owners who had bought recently in flooded neighbourhoods could face "significant losses" if they resold now, she said.

.....and the unfortunates who've built on known flood plains will suffer even larger premium increases as the insurance industry
attempts to claw back its "costs"

Remember in Queensland how they've had bad floods over the last say 5 years? Some years, whole towns submerged etc.
Well that was the equivalent of the earthquakes in Christchurch here. Insurance premiums went up heaps, and in some cases you couldn't insure, which meant you couldn't get mortgages. Some people lost all their money.
So if the flooding happens again and again, this sort of thing could happen here.Squadly dinky do!

you could get a storm water engineer to comment Sometimes these flood areas are due to bottlenecks in the drainage systems that cause back up and they get fixed in due course but the zoning stays because they forget that the problem has been addressed. Flooding also mean sheet flooding down a slope that may only mean 50mm of water but you need to ensure you dont block the flowpath with fencing or solid construction.
