Coastal Hazard Adaptation Strategy (CHAS)

Surfer Swell Currumbin Sunrise

The Queensland State Government has funded the QCoast2100 program to help local government build resilience to coastal hazards.

Council has been successful in obtaining funding to complete this body of work which will help meet our objectives in the City Plan and the Corporate Plan.

The CHAS aims to facilitate the development of high quality information enabling defensible (legally, socially and economically), timely and effective local adaptation decision-making across key areas of planning and operation such as:

  • land use planning and development assessment;
  • infrastructure planning and management including roads, stormwater and foreshores;
  • asset management and planning including nature conservation, recreation, cultural heritage values and other public amenities;
  • community planning; and
  • emergency management.

Local governments are required to prepare their CHAS having regard to the minimum standards and guidelines which can be found on the Local Government Association of Queensland (LGAQ) and QCoast2100 websites.

Why prepare a CHAS?

The Gold Coast City Plan details the overarching principles that are to guide land use and development decisions including the consideration of natural hazards. This includes hazards such as coastal erosion, storm tide inundation and future inundation due to projected sea level rise of 80 centimetres by 2100.

Anthropogenic sea level rise has the potential to impact on the functionality and durability of essential public assets (water supply network, stormwater assets, roads, footpaths and cycle paths) which contribute to the city’s liveability and attractiveness. In addition to higher rates of sea level rise, the impacts of extreme weather events and exposure to higher probability storm events (i.e. stronger and more intense storms) will also contribute to the deterioration of valuable assets such as parks and open space.

The City already undertakes a strong program of coastal management work that enables the City to absorb the impacts of coastal erosion. The CHAS will enhance the social, economic, environmental and land use planning objectives this program of works supports.

Defending the shoreline, both along our ocean beaches and along the immense and complex networks of artificial and natural waterways will always remain a long term adaptive measure to address coastal erosion. In addition to this, the CHAS will consider other potential adaptive approaches such as avoid, build capacity or accommodate anticipated future changes.

The CHAS will enhance our ability to identify adaptation option for our City which will improve our City’s resilience up to and beyond the year 2100.

Consultation will be undertaken throughout the development of this body of work with key asset owners and community input.

The development of the CHAS will follow eight phases:

Phase 1: Plan for life of project stakeholder communication and engagement.

Phase 2: Scope coastal hazard issues for the area of interest.

Phase 3: Identify areas exposed to current and future coastal hazards.

Phase 4: Identify key assets potentially impacted.

Phase 5: Risk assessment of key assets in coastal hazard areas.

Phase 6: Identify potential adaptation actions.

Phase 7: Socio-economic appraisal of adaption options.

Phase 8: Strategy development, implementation and review.
