A stormwater management strategy for the Brownhill and Keswick Creek catchment has been approved by the five councils involved in the project.

Adelaide, Burnside, Mitcham, Unley and West Torrens Councils have all endorsed a strategy which calls for the commencement of the bulk of proposed flood mitigation works throughout the region, including construction of detention basins, creek diversions and channel upgrades across the catchment worth over $100 million.

The agreed strategy also commits to further investigation over a 12-month period of alternative options to the proposed flood control dam in Brownhill Creek Recreation Park while other flood mitigation works in the catchment get underway.

Michael Salkeld, Project Director of the Brownhill Keswick Creek Stormwater Project, says council endorsement of the strategy now enables the draft stormwater management plan – as proposed last year by consulting firm WorleyParsons – to be updated and submitted to the Stormwater Management Authority for approval.

“This is another important step in finalising and implementing an effective stormwater management plan for the Brownhill Keswick Creek catchment,” he said.

“Representatives of the five councils have briefed the Stormwater Management Authority on the strategy, with the updated stormwater management plan to be submitted to the Authority by August.

“We envisage commencing flood mitigation works in early 2013, starting with the construction of a flood detention basin and stormwater harvesting facility along Glen Osmond Creek in Ridge Park at Myrtle Bank.”
