The St Morris Reserve Upgrade forms part of the Council’s Trinity Valley Stormwater Upgrade Project to manage flooding in the suburbs of St Morris, Trinity Gardens, Maylands and Stepney.

The Federal Government is contributing $9.9 million as part of its Preparing Australian Communities Program, which targets projects that improve resilience against natural disasters. The investment is being matched dollar by dollar by the Council, resulting in a near $20 million investment to reduce the risk of flooding.
