Description:
Western Downs Regional Council (WDRC) were undertaking a parklands development at the Tara Lagoon that included reconstruction of a pathway that crossed the creek inlet to the lagoon. Previously the culvert crossings had been destroyed by flood waters and erosion of the mouth of the creek into the lagoon was evident.
Black & More were asked to provide a more permanent and effective design solution for the two creek crossings and 150m of adjacent pathway, which were prone to flooding and scouring in heavy weather events.
Detailed design documentation was provided to WDRC that proposed to realign the pathway to higher ground, removing the need for one of the culvert crossing and utilising a causeway as an alternative. The realignment would reduce the size of the other culvert crossing and lessen the number of protective treatments required. This saved considerable amount of construction costs, allowing Council to monitor the erosion of the creek inlet and integrity of the lagoon banks, without compromising the pathway structure.
