Certainly pollution would be an issue for mangroves. We'll have to wait and see what an EIS comes up with.
As for flooding, I hope they keep in mind the possibility of rising sea-levels.

You know, honestly I don't think we have to worry too much about rising sea levels. If it really becomes an issue, we can always just build a huge sea wall barrier like they did in New Orleans stretching all the way from Cape Jervis to Kangaroo Island to the Yorke...

All presently looks a very barren entry to Adelaide - I am glad they are thinking of changing the land use. Yes, sea levels could be an issue - particularly depending on coastal dunes and what is done with them, levees, king tides etc.
How long did reclamation and treatment of the land take before West Lakes area was built up? Would it be similar here?
As generally indicated the process it appears to me that salination of the land and height above sea level would be the key issues.
I wonder if they'll propose canal style development? (Good opportunity - with the sea change trend the way it is).

No sand dunes up there, salt pans and then mangroves along the shore. There are embankments.

I don't think reclaiming this land will be cheap. If they keep portions for sea canals it may work a bit better, but I'm not too sure what the impact would be on the mangroves along the North Arm and Broad Creek, etc.

lol, the buckland park "township" is well on its way to lose its character (the character of it being a town) well before it's built

Not sure how this is going to affect things, article from
the Australian,
Business (online).
(Ridley is the current land owner).
Ridley stocks rise on GrainCorp share offer
Ray Brindal, Dow Jones Newswires | May 16, 2008
AUSTRALIAN agribusiness GrainCorp has made a share-based offer for Ridley Corp that puts an enterprise value of $592 million on the stockfeed manufacturer.
GrainCorp (ASX: GNC: quote) will offer one of its shares for every nine shares of Ridley (ASX: RIC: quote), representing an implied offer price of $1.39 for each Ridley share, based on GrainCorp's $12.48 closing price yesterday.
Ridley shares were trading higher by 3.46 per cent at $1.345 this afternoon, and GrainCorp was down 2.24 per cent at $12.20. At the same time, the benchmark S&P/ASX 200 Index had gained 1.14 per cent.
GrainCorp managing director Mark Irwin said the proposed purchase had a strong strategic rationale for both companies.
"The acquisition of Ridley will further consolidate our strategy of being Australia's leading handler and supplier of agriproducts and bulk products," he said.
GrainCorp already has a relevant interest of 19 per cent of Ridley's shares through pre-bid acceptance arrangements, he said.

.......Perhaps we'd best not follow the New Orleans example.

How will the houses avoid salt damp - and how will plants grow - are all the houses gonna have salt bush as their gardens??

Thanks for the info Ho Really. Have not been to the area since 1986 and seemed to remember that the embankments were dunes - out of bad memory.
Yes, the canals may affect the mangroves, which I did not think were so close. Hope they find a way around this - canals can be very attractive - but expensive too!

How much reclamation do they have to do to avoid this?

I doubt that when and if they start building homes, they will build right up to the mangroves.
There will probably be some wet lands or parklands between the mangroves and development. Its an extremely large site.

The site will be cleaned up. Take the housing developments in Brompton as an example. The soil was contaminated with all sorts of poisonous and hazardous materials, but it was cleaned up. Remediation or something I think is the correct term.

This would be a lot more complex than a contamination clean up, because it's not just soil. The entire water table of the area would have high levels of salt.

The area would probably require obviously the surface salt taken away. Then an amount of clean fill spread over the surface, maybe 2metres thick. It would be critical to stop surface water building up in order to prevent the saline water below coming up. Salt resistant trees would be excellent, eg. norfolk island pines like around glenelg (which have their roots into the sand along the beach and get along just fine.) Once soil level is above sea level and some vegitation is in place, salt levels should start to decrease.
