Barongarook Creek rock wall project to protect Scout Hall and Lions Park

The flood-damaged banks of the Barongarook Creek near Murray Street will be rock beached to protect the Lions Park and Scout Hall against future flood events.

Designed to withstand a one in 100 year flood, large round basalt rocks will be strategically positioned along the Barongarook Creek in the areas that sustained the most damage in last year’s September 14 flood.

Corangamite Catchment Management Authority is leading the project in partnership with Colac Otway Shire Council. Work will start in late spring 2017, weather dependant.

The Corangamite CMA has successfully shored up many river beds and banks using various rock armouring methods throughout the region including several large areas in the Barwon and Otway Coast Catchments.

Mayor Chris Potter said the priority was to protect both the Lions Park and the Scout Hall from any further erosion of the Barongarook Creek’s stream banks.

“Last year’s flood was close to a one-in-20-year flood event and the rushing water took out a considerable chunk of the creek bank near the Scout Hall, as well as the footbridge linking the Lions Park to the common area near the Scout Hall,” Cr Potter said.

“This rock beaching will prevent future widening or deepening of the creek in the Lions Park area and we’re really pleased to work with Corangamite CMA on this project.

“Council will install a new footbridge once the rock beaching project is complete.”

Corangamite CMA Board Chair Alice Knight said there would be about 180 lineal metres of rock beaching installed in total, on both sides of the creek.

Ms Knight said the highly visible sections of rock beaching would be designed in an attractive stepped boulder formation, while the less visible sections would be standard rock beaching.

“The stepped boulders create secure spaces for native shrubs and grasses to grow, which not only makes the creek bank visually appealing but adds to the environmental values of the area,” Ms Knight said.

“The rock beaching will add extra stability to the areas of the creek where the floodwater hits the hardest, which is typically where the stream bed curves.”

Cr Potter said the rock beaching was one of three projects that would further enhance Colac’s eastern city entrance.

“During the next two years there will be a lot of work taking place at the eastern entrance to Colac in addition to the rock beaching.

“The CBD Revitalisation Project is starting in August and will include the establishment of a pocket park on the corner of Murray and Queen streets, which will provide an attractive green space on the edge of our CBD.

“VicRoads also has some exciting plans for the upgrade of the bridge over the Barongarook Creek which will further add a sense of arrival to our CBD.”

The rock beaching work will take about a fortnight to complete. Car and pedestrian access to the Lions Park area will be restricted during the work.

The rock beaching project is jointly funded by the Australian and Victorian governments under the Natural Disaster Relief and Recovery Arrangements.
