Coastal Planning

The City of Busselton's coastline, especially the low, sandy and extensively developed Geographe Bay coastline, has always been subject to coastal erosion and shoreline movement, with different portions of the coast eroding or accreting at different times. This process has historically been influenced by a number of factors, principally weather and ocean current patterns, and their interaction with changes in the shape and location of beaches, sand bars, coastal structures and the rest of the marine environment. As these things change, sections of the coast have switched from experiencing periods of net erosion to periods of net accretion and vice versa. The way this issue is perceived has also changed in recent years as knowledge has increased on the potential impacts of climate change induced sea level rise, related changes to weather and ocean current patterns, and their potential impacts on coastal erosion and shoreline movement.

This is an issue of concern to the community and the City, and there have been a number of coastal erosion and inundation studies undertaken for the City of Busselton's coast.  Most recently, in 2012, the City commissioned modelling using the latest available base data, that consisted of more accurate digital topology information and recent actual shoreline movements.  In addition the Western Australian Planning Commission issued a position statement stating that coastal planning is undertaken on the basis of an estimated 0.9 metres sea level rise over 100 years.

Access to the City's Interim Coastal Erosion Modelling can be obtained by:

  • Agreeing to the PUBLIC TERMS OF USE and clicking on the "I Agree" link below; or
     
  • Viewing the City’s Online Mapping system and selecting the Interim Coastal Adaption Area Layer to show you land within a 150 metre setback line from Horizontal Setback Datum (HSD) - this distance gives a guide to the minimum setbacks of development from the coast in accordance with the Department of Planning’s State Planning Policy (SPP) 2.6;

The Council has resolved that the City will now consider potential coastal erosion risk issues associated with any proposal for development between the existing coastline and 150 metre setback line on the maps.

The City continues to progress with the development of more comprehensive coastal adaptation planning, and the approach to the issue may change over time.
