The State Government, five local councils and the Stormwater Management Authority have reached a historic agreement on a $140 million infrastructure project to safeguard against flooding in the Brown Hill and Keswick Creek catchment – the most at risk area for flooding in Adelaide.
The flood mitigation works detailed in the Brown Hill and Keswick Creek Stormwater Management Plan which has been 10 years in the making, will reduce the number of properties affected by a 1-in-100 year flood event by nearly 98 per cent. The infrastructure project will deliver about 73 full-time jobs during construction.
The plan will also yield more than $240 million in community benefit in terms of damage mitigation, reducing flood impacts on Adelaide Airport, minimising economic disruption, and improving stormwater quality across the catchment.
The announcement was made today by Water and River Murray Minister Ian Hunter; Lord Mayor Martin Haese (Adelaide); Mayors David Parkin (Burnside), Glenn Spear (Mitcham), Lachlan Clyne (Unley) and John Trainer (West Torrens); and SMA Presiding Member Stephen Hains.
The councils and State Government have called on the Commonwealth to contribute funding toward the project, and will be actively lobbying for this contribution in order to expedite construction and reduce the burden on ratepayers.
The State Government has agreed to fund 50 per cent of the required works via its Stormwater Management Fund over the next 20 years.
