Coastal Dune Resilience Project – East Busselton

Published on Friday, 24 January 2025 at 7:00:00 AM

The City of Busselton is rehabilitating and enhancing coastal dunes and refurbishing the coastal path along Geographe Bay Road to increase their resilience to coastal erosion and flooding.

Project Objectives

To enhance the capacity for the coastal dunes to resist erosion, and to adapt the coastal path in selected low lying areas of East Busselton, identified through coastal modelling as pathways for coastal flooding, and mitigate risk of coastal inundation.

Project Scope

A hybrid solution of using nature-based techniques on coastal dunes to improve resilience to erosion and adapting existing coastal paths to reduce coastal flooding has been adopted. The capacity of the coastal dunes to resist erosion will be improved by increasing the volume of degraded low-lying dunes. Beach sand for dune rebuilding will be imported to the dunes or relocated from adjacent beaches where ongoing accretion occurs. Selective planting of native species will be undertaken to both increase the resilience of the dune surface to erosion, and to restore or enhance the ecological function of the coastal dune habitat. Refurbishing the coastal path will provide a minimum crest level in certain areas, with improved scour protections against erosion. This also allows path amenity to be improved by widening and resurfacing.

Project Timing

The project will commence 28 January 2025 and is scheduled for completion end of March 2025 (subject to weather conditions).
