00:01Concrete drain panels stripped away by the sheer weight of water.
00:07Some say the damage from the weekend's downpour is decades in the making.
00:12Obviously this watercourse was here before Canberra was built
00:15and in the 1971 floods unfortunately we lost lives
00:19and the creek infrastructure as you see it today was designed back then.
00:23Well since then we've got much better knowledge about watercourses and nature-based planning.
00:29A Legislative Assembly inquiry is examining changes touted as a housing solution that avoids urban sprawl.
00:37But there are fears existing infrastructure will struggle.
00:40We need 40% of blocks to be permeable to absorb some of the runoff when we get these kind of sudden rainstorms.
00:48It's better to put sediment ponds and some mitigation measures back into the creek, naturalise it, bring some of the ecology back.
00:57Engineers agree there's work to be done.
01:01My analysis that was done nearly a decade ago said quite clearly
01:05there's some areas that you couldn't densify beyond what was already there
01:09and could not be developed unless you looked at local solutions
01:14and stormwater had to be in that planning policy mix.
01:19The Government insists capacity and climate change is being accounted for.
01:24There's a requirement for developments to have permeable surfaces and planting areas to hold that water within their sites.
01:31And then for water that leaves the block and goes into the stormwater network
01:35we've got a rolling program of infrastructure studies, capacity upgrades and targeted sort of interventions.
01:44Downstream problems requiring mixed solutions.
01:49The focus is still in the areas that are physically affected by nutrient cleanliness.
01:52The main problem is the minimum number of human resources.
01:54The minimums cost of the basic mission is also to make sure that the listeners are being attacked by your local sciences.
01:55If you can, you can see the same number of human-levels.
01:56The minimum begins the minimums in the middle of the region.
01:57The minimums in the middle of the region is the minimum of the country.
01:59The minimums in the main-levels for the museum and the central bank-levels for the museum.
02:01The minimums are to remove the entiree, and the 1-levels for the museum in the field to cover the museum.
