Coastal Hazard Adaptation Strategy

Also in this section...

The Queensland Government has made a commitment of $12M over 3 years to assist eligible coastal councils in the preparation of a Coastal Hazard Adaptation Strategy (CHAS) relevant to their specific coastal issues. The program is managed by the Local Government Association Queensland and is titled QCoast2100

Moreton Bay Regional Council has been successful in obtaining funding under the QCoast2100 program to develop a CHAS for coastal areas within the council area.

Why do we need a CHAS? 

Coastal areas experience a range of impacts including beach erosion, coastal recession and inundation.  These impacts and the damage caused can be significant when associated with a major storm event, cyclone or east coast low.

Traditionally, Council has sought to reduce the effects of these hazards through a range of measures including:

  • undertaking coastal management activities such as sand dune restoration, beach replenishment and the provision of protective works
  • establishing appropriate planning, development and design standards

To date management of coastal hazards has been largely undertaken in response to a particular event or impact rather than as part of a broad, holistic and pro-active approach.

In recent years there has been discussion concerning climate change and the potential impacts associated with the anticipated changes.  Climate change has the potential to increase coastal hazards as a result of sea level rise and the increased intensity of cyclones and storms. These changes have the potential to:

  • accelerate coastal erosion
  • permanently inundate low lying areas
  • increase the impacts associated with storm surges and king tides.

When completed the CHAS will provide a consolidated view of hazards that are anticipated to impact our coastal areas within the short, medium and long-term horizons and how these hazards can best be managed.

Benefits

As noted in the previous section the CHAS must consider the potential impact of climate change related hazards across a long-term planning horizon.  Within the QCoast2100 Developing a CHAS Minimum Standardsand Guidelines [PDF 5.7MB] the following benefits are noted:

  • identify the likelihood and consequence of coastal hazards having an adverse impact on council operations and community assets 
  • reduce future exposure to the risks of coastal flooding, storm-tides and erosion 
  • reduce or avoid significant financial costs of future coastal hazard impacts 
  • clarify council's role in responding to future coastal hazard risks and setting the direction for this response 
  • embed coastal hazard adaptation responses into decision making processes and planning frameworks 
  • respond effectively to statutory planning and policy direction at the State level e.g. State Planning Policy 
  • plan for the long-term protection of coastal infrastructure, built environment and services within at-risk areas 
  • build the knowledge and capacity of council and the community to respond to coastal hazard planning needs and events
  • prepare for engagement and consultation with the broader community to inform decision-making. 

Phases

Council has been successful in receiving grant funding approval totalling $500,000 towards development of a CHAS.  Based on current timeframes it is anticipated that the project will be completed around June 2019.  In accordance with the QCoast2100 Developing a CHAS Minimum Standardsand Guidelines [PDF 5.7MB] the following 8 phases are to be followed:  

  • Phase 1: Communication & Engagement
  • Phase 2: Scoping Study (gap analysis)
  • Phase 3: Identifying areas exposed to current & future hazards (completion of additional relevant studies identified within Phase 2)
  • Phase 4: Identifying assets potentially affected
  • Phase 5: Risk assessment of potentially affected assets
  • Phase 6: Identification of potential adaptation options
  • Phase 7: Socio-economic appraisal of potential adaptation options
  • Phase 8: Finalise: Coastal Hazard Adaptation Strategy
