The study recommends the modifications to the upstream reservoirs increasing flood storage capacity of Crusoe Reservoir and redirect runoff from between Sandhurst and No 7 Reservoirs into Crusoe Reservoir using a catch drain system.
This option was the most feasible option with the higher benefit-cost ratio, strong community support, provides protection to the greatest number of properties, resulting in a significant reduction of flooding and damages associated with it.
The recommendation is to proceed to the next stage of design, which will consist of functional and detailed design.
