Riverlea (Buckland Park) | 12,000 dwellings | $3b

[SBD]

I don't live in Riverlea, I was just visiting, I live in the Eastern suburbs. If I had known it was so far from civilisation I would have brought a packed lunch and filled up in Salisbury or Gepps Cross. You all realise that before the Government decided to call this project Riverlea it was known as The Lower Light Flood Plain.

EBG B. Eng. (Civil).

Riverlea Park (suburb named by the Government - Riverlea is the housing estate named by Walker Corp) would not have been the Lower Light Flood Plain as it's south of the Gawler River. The Light River is north of Two Wells.The water features in Riverlea Park are supposedly designed to channel the flood water from the Gawler River safely away to the Thompson Creek outflow (adjacent to the Bolivar outflow drain) as normal ground level is below Gawler River flood level.It's the same as if the lower Torrens overflows, the excess ends up in the Patawalonga outflow.

Can we rename the development Riverleak?

Buckland Park still exists. It's west and south of what's now RIverlea Park.

I've noticed as well quite a few of the homes built, have a noticeable elevation from the footpath, about a foot or 2 or there about's.
Most houses have some drop from the home to the foopath anyway, so not sure if it's just the way they've done the front yards to be able to build those small retaining walls on the front and side boundaries, or if it's perhaps for some small flood mitigation?

I think that is likely deliberate as part of the flood mitigation works. Housing in floodable areas near the Murray River and its Victorian and NSW tributaries and anabranches have minimum floor heights above expected flood levels, often built on top of slight mounds above the street and back yard. I've noticed at least one of the estates near Roseworthy seems to have similar construction requirements where the land east of the Horrocks Highway is higher so runoff will inevitably cross to the lower estate before being channelled to a drain and ultimately the Gawler River.

There has been major infrastructure built for flood mitigation upstream of Gawler, but there is now also significant development happening in Roseworthy, Angle Vale, Evanston, Concordia, etc all of which will eventually drain to the Gawler River, and hard surfaces lead to shorter, higher floods.

Looks like most of Riverlea is in the clear?
Of course who knows how the recent and coming development may impact the flow of water in such an event or worse.

funny the same government that tells us sea levels are rising due to climate change puts a new housing dev on a flood plain

Maybe that's the reason for the elevated construction, and that the water features are intended to be salt water not fresh water.
