Wollongong Coastal Zone Management Study and Plan

Wollongong City Council required preparation of a Coastal Zone Management Plan in accordance with new guidelines issued by the NSW Government, which require a risk-based approach for coastal zone management plans. BMT WBM's experience in ISO 31000:2009 Risk Management was applied to the preparation of Wollongong's Coastal Zone Management Plan.

Wollongong City Council required preparation of a Coastal Zone Management Plan in accordance with new guidelines issued by the NSW Government, which require a risk-based approach for coastal zone management plans.  BMT WBM’s experience in ISO 31000:2009 Risk Management was applied to the preparation of Wollongong’s Coastal Zone Management Plan. The process involved: 

  • Extensive GIS spatial processing combined with local knowledge from community consultation to spatially define risk ‘consequence’;
  • Transferring findings from an existing coastal hazards study for Wollongong into  a risk ‘likelihood’ format;
  • GIS processing of ‘likelihood’ and ‘consequence’ to produce mapping of risk across Wollongong’s coastal zone, for erosion and recession, coastal inundation and coastal influenced geotechnical hazards;
  • Preparation of management options to treat high and extreme risks for the current to 2100 timeframe, which were deemed intolerable  by Council;
  • Definition of triggers for implementing the options, to delay significant or difficult actions until impacts become imminent;
  • Cost benefit analysis and economic analysis of options; and
  • Recommended actions for implementation, within an implementation schedule.

The project was the first of its kind to apply a risk-based approach that conforms with the international standard (ISO 31000:2009) to a Coastal Zone Management Plan in NSW.
