In September 2014, the ‘Part B Report’ was released detailing investigations into eight options to mitigate flood risks in upper Brown Hill Creek.
A brief summary of the report produced for community consultation in 2015 can be found here.
All options involved two types of work along upper Brown Hill Creek to reduce the risk of flooding during high stormwater flows:
- Creek capacity upgrade works in critical sections (which vary for the eight options) – to increase the capacity of the creek so it can carry more water; and
- Creek rehabilitation works along its full length – to rehabilitate the creek towards achieving ‘good condition’ in order to assist flow capacity along the full length of upper Brown Hill Creek and improve its creek biodiversity.
Under the Natural Resources Management Act, creek owners are responsible for maintaining the creek in good condition. This is explained in the brochure “Urban Creeks – A property owner’s guide to managing healthy urban creeks’ produced by the Adelaide and Mount Lofty Ranges Natural Resources Management Board (AMLRNRMB) in conjunction with the City of Burnside, which can be accessed here.
A six-week consultation process on the Brown Hill Keswick Creek Stormwater Project’s Part B Report for upper Brown Hill Creek occurred between May 13 and June 23, 2015. The outcomes of the community consultation process were then reported to the five catchment councils. View the full community consultation report of September 2015 here.
In September 2015, the five catchment councils unanimously agreed on Option D – ‘Creek Capacity Upgrade’ – as the preferred option for Part B Works. The proposal is outlined in Section 12 of the 2016 Stormwater Management Plan.
