Key Facts

The Mindarie Breakwater was constructed in 1988 and management responsibility was handed to the City of Wanneroo in 2005. Since this time the City has undertaken a number of technical investigations, monitoring, risk mitigation measures and minor maintenance works.

Phase 1 Maintenance works were undertaken in 2017/18 which focussed on a 160m length of the Mindarie Breakwater which experienced significant wave overtopping and displacement of rock debris onto the road during storms. The completion of these works increased and widened the crest level of the structure resulting in less wave overtopping and associated safety issues.

The Breakwater Maintenance Detailed Design Study will identify the appropriate breakwater maintenance option to ensure the ongoing functionality and safety of the structure into the future.

Phase 2 Maintenance works are currently scheduled for 2020/21. These works may be staged over a number of years and are dependent on the outcomes and recommendations of the Mindarie Breakwater Maintenance Options Assessment and Detailed Design Study.
