Project overview
The City of Wanneroo Coastal Hazard Risk Management and Adaptation Plan (CHRMAP), which was completed in 2018, identified a number of sites vulnerable to coastal erosion along the Yanchep coastline. This study recommended that a detailed options assessment is conducted for the management of coastal vulnerability at Yanchep. Additionally, since 2018 excessive winter storm erosion has resulted in the need for ongoing beach renourishment at the Yanchep Lagoon to maintain beach access, minimise loss of dune and improve beach functionality/amenity.
Recent coastal erosion issues and CHRMAP recommendations form the basis behind the Yanchep Coastal Management Project which aims to address the current and future coastal erosion and beach access issues along the Yanchep coastline through the implementation of coastal management measures. These coastal management measures will be identified through the completion of a detailed coastal engineering consultancy study consisting of a coastal processes assessment, coastal management options assessment, extensive community and stakeholder consultation and detailed design. The City has engaged coastal engineering consultants Stantec to complete this study.
Completion of this project will assist with the management of ongoing coastal erosion issues along the Yanchep coastline and will lead to the protection of coastal infrastructure, minimise the loss of dune environment, enable ongoing safe beach access for beach users and surf life saving activities and improve the functionality and amenity of some of the City's most popular beaches.
Study update
The City has engaged coastal engineering consultants Stantec to complete the detailed coastal engineering consultancy study. The coastal processes assessment and the coastal management and beach access options assessment are now complete and consultation with the community and Aboriginal Knowledge Holders is now underway.

Stage one - Coastal processes assessment
Stage two – Coastal management and beach access options assessment
The City of Wanneroo established the Yanchep Coastal Management Advisory Group consisting of Council Members, City Staff, Community Representatives and a State Government Representative in December 2024. This group meets quarterly or at major project milestones providing valuable input into the assessment and recommendations of the Yanchep Coastal Management Study. The City of Wanneroo is also engaging with Aboriginal Knowledge Holders for Yanchep to seek input into the development of appropriate coastal management measures.
This project is partly funded by the State Government via Department of Transport and Major Infrastructure Coastal Adaptation and Protection (CAP) Grants in 2024/25 and 2026/27.
