Coastal Planning

Modelling the risk of erosion

Erosion risk has been modelled using 0.9m sea level rise and storm event scenarios and mapped to identify the potentially vulnerable areas of the City’s coastline.

The City's Interim Coastal Erosion Modelling is available by:

  • Visiting the Interim Coastal Erosion Modelling Maps page; or
  • Viewing the City’s Online Mapping system and selecting the Interim Coastal Adaption Area Layer (within the ‘General Enquiry’ module). The 150 metre setback line from Horizontal Setback Datum (HSD) indicates the minimum development setback from the coast.

The City will consider coastal erosion risk issues associated with any land use proposal between the existing coastline and 150 metre setback line on the maps.

Managing coastal erosion

The City of Busselton has implemented its second Coastal Management Program (2018-2028), which is a 10 year whole of coast strategy that covers the entire Geographe coastline.

More information on current coastal management can be found here.

The future in coastal planning

In February 2021, the Council adopted a draft Coastal Hazard Risk Management and Adaptation Plan (CHRMAP), in accordance with State Planning Policy 2.6 State Coastal Planning Policy (SPP2.6). The CHRMAP identifies the current and potential extent of risk (over the next 100 years) to private assets, public infrastructure and environmental/social/cultural values from coastal hazards, such as erosion and inundation, due to storm events and currently projected sea level rise. The CHRMAP also sets out a framework for recommended adaptation responses to identified risks.

Community consultation has contributed to the development of the CHRMAP through the Community Coastal Values Survey (2018) and several public information sessions. To view the CHRMAP and find out further information on community and stakeholder consultation go to the City's Your Say Busselton engagement portal
