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

Looking to the future, the City is preparing a Coastal Hazard Risk Management and Adaptation Plan (CHRMAP).

The CHRMAP will identify areas that could potentially be impacted by coastal erosion and flooding hazards, over the next 100 years, due to storm events and the estimated rise in sea level.

The purpose of the CHRMAP is to consider potential hazards, and together with feedback through community consultation, will recommend management responses for the future.
