Betty Long Gardens creek upgraded
A section of Upper Brown Hill Creek at Betty Long Gardens, Torrens Park, has been upgraded as part of the Brown Hill Keswick Creek Stormwater Project.
The condition of the watercourse had been significantly impacted by high flow events in 2005, 2016 and 2023 which caused the erosion of the creek bed and undermining of channel banks.
As part of the project, care was taken to protect significant Kauri trees located along the top of the western bank.
New gabion walls have been constructed with limited disturbance to existing channel banks and are filled with sandstone quartzite stones to prevent erosion. The baskets are durable and flexible and will tolerate future ground movements. Landscape works will continue to be delivered in coming weeks.
Work is also underway to upgrade the channel at Hawthorn between Cross Road and Hampton Street, a known flooding hotspot, including the construction of a new culvert crossing at Hampton Street with new footpaths installed on both sides of the road.
