Stage 4 of the project involves upgrading the flow capacity of Upper Brown Hill Creek and Glen Osmond Creek to prevent ‘break-outs’ and flooding of private property. Key hot spots are being targeted to align with grant funding opportunities.

4A Anzac Highway to Third Avenue, Everard Park

Located between Anzac Highway at the downstream end and Third Avenue at the upstream end, these works were expedited to take advantage of site access that would be significantly restricted following completion of an adjoining high density residential development. The project involved replacement of a 140 metre length of open concrete channel with an increased capacity underground culvert.

Subsequent to installation of the culvert, the City of Unley delivered ground level improvements to extend Wilberforce Walk to Anzac Highway, with a shared use path for pedestrians and cyclists traversing the culvert.

Culvert construction was completed in August 2020, at which point the site was handed over to City of Unley for delivery of shared use path improvements.

4B Third Avenue to Leah Street, Forestville

The Board has recently commenced the design process for the section of channel upgrade between Third Avenue at the downstream end and Leah Street at the upstream end. Over the coming months, the Board will be undertaking site investigations to inform the design process, including ground and tree surveys and soil sampling. There will be opportunities for community information and feedback in the coming months and construction is scheduled to commence late in 2025.

Funding for this project is being provided under the Commonwealth Government’s Disaster Ready Fund.

4E DIT Diversion Culvert

A section of Brown Hill Creek in Forestville was diverted by the Department of Planning, Transport and Infrastructure (now the Department of Infrastructure and Transport) in 2013 as part of the Goodwood Junction Rail Upgrade Project.

The works, delivered in collaboration with and funded by the Brown Hill and Keswick Creeks Stormwater Board, involved diverting the creek into a new underground culvert constructed generally along the eastern side of the railway corridor from the southern side of Victoria Street to the northern side of the Glenelg Tramway. The culvert discharges into the existing Brown Hill Creek channel within Forestville Reserve.

4H Orphanage Park

The Board has recently commenced the design process for the channel upgrade through Orphanage Park. Over the coming months, the Board will be undertaking site investigations to inform the design process, including ground and tree surveys and soil sampling. There will be opportunities for community information and feedback in the coming months and construction is scheduled to commence late in 2025.

Funding for this project is being provided under the Commonwealth Government’s Urban Rivers and Catchments Program.

4J Regent Street to Malcolm Street, Millswood

Works are underway to double the capacity of this section of Brown Hill Creek, from just downstream of Regent Street to Malcolm Street at the upstream end, including upgrade of the Regent Street culvert.

The entirety of the creek in this location traverses through privately owned property and the project team have been engaging closely with property owners over the course of design development and during construction.

Delivering in a heavily constrained environment, the works have been designed in collaboration with property owners to meet the flow capacity requirements while being sympathetic to the natural environment and the individual and unique objectives of each owner.

4N Cross Road to Hampton Street, Hawthorn

The Board has recently commenced the design process for the section of channel upgrade between Cross Road at the downstream end and Hampton Street at the upstream end, including the Hampton Street culvert. Over the coming months, the Board will be undertaking site investigations to inform the design process, including ground and tree surveys and soil sampling. The creek in this location is located within privately owned property and the Board’s representatives have commenced engagement with property owners regarding the design.

Funding for this project is being provided under the Commonwealth Government’s Disaster Ready Fund.

4Q Hawthorn Reserve

The City of Mitcham upgraded the Hawthorn Reserve precinct in 2018/19 and the creek upgrades were expedited to coincide with this project.

The creek has been widened to ensure sufficient capacity and the banks have been laid back with native plantings in the area adjacent the Mitcham Library to retain a natural setting. Stepping boulders and logs have also been installed to create an active nature play space for use when the creek is dry or not flowing. Further downstream, rock filled gabions have been installed and a floodwall has been constructed at George Street to contain creek flows.

4T Betty Long Gardens

The Board has recently commenced the design process for the section of channel upgrade which traverses Betty Long Gardens and adjoining privately owned properties in Torrens Park. Over the coming months, the Board will be undertaking site investigations to inform the design process, including ground and tree surveys and soil sampling. The creek in this location is located partially within public open space and partially within privately owned property and the Board’s representatives have commenced engagement with property owners regarding the design.

Funding for this project is being provided under the Commonwealth Government’s Urban Rivers and Catchments Program.
