Significant structural changes will be made to the groynes at Port Geographe as the State Government implements the recommendations of a three-year study and detailed computer modelling investigating excessive seagrass accumulation and erosion at the Busselton site.
Transport Minister Troy Buswell said the $28.15million project would modify the shape and length of the western breakwater; remove the pocket beach groynes to eliminate trapping of seagrass and sediment; realign the foreshore; and change the eastern seawall to address beach erosion at Wonnerup.
Mr Buswell said the Government’s investment in the site would have substantial benefits for the lifestyles of current and future residents of Port Geographe and give the wider community improved amenity and access to beaches in the area.
“The extensive research, investigation and modelling undertaken has provided the basis for structural changes that will address health issues, improve amenity and reduce ongoing annual coastal maintenance costs,” he said.
“Importantly, the decision to fund the structural changes will also improve the viability of the currently stalled development.”
The Minister said the Department of Transport (DoT) intended to call for tenders in 2013, with work on site proposed to start in July 2013 following necessary environmental and planning approvals.
In 2007, DoT and City of Busselton commissioned UWA to undertake comprehensive study investigating seagrass movement in Geographe Bay
200 page study Seagrass Wrack Dynamics in Geographe Bay recommended a further detailed computer modelling of proposed structural changes at Port Geographe
