Geraldton Coastal Hazard Risk Management and Adaptation Planning Report

The City is facing the impacts of coastal erosion and inundation along its coastlines, with the vulnerability of land use and development within the coastal zone expected to increase in the future. In accordance with Western Australia's State Planning Policy 2.6 State Coastal Planning Policy (SPP2.6), coastal areas identified as being at risk of coastal hazard require Coastal Hazard Risk Management and Adaptation Planning (CHRMAP). The Geraldton CHRMAP Report was developed following extensive community engagement and adopted by Council on 27 November 2018 to inform the development of local coastal planning policies.

The City received grant funding from the Western Australia Planning Commission through the Coastal Management Plan Assistance Program to develop the Geraldton CHRMAP.

Adapting to Coastal Erosion and Inundation Process

Adapting to coastal erosion and inundation involves a process of developing a CHRMAP and then using the document to inform the development of a Local Coastal Planning Policy. Currently, the City is now in Stage 3 of a four Stage process to assist in adapting to climate change and rising sea levels.  These final stages involve policy development which will guide actions to be taken when and if coastal assets become at risk to erosion or inundation.

Timeline Flowchart

Adoption of the Geraldton CHRMAP Report

The Geraldton CHRMAP Report was adopted by Council on 27 November 2018. At that time, Council also resolved to:

  • Undertake further geophysical investigations of the shoreline areas in Drummond Cove, Sunset Beach and Bluff Point;
  • Undertake coastal monitoring of the beach at Drummond Cove and investigate medium-term coastal adaptation options as Sunset Beach outlined in MP Rogers Sunset Beach Adaptation Options Advice;
  • Seek formal advice from the State Government on its position with respect to the future funding of coastal protection works; and
  • Initiate Stage 3 of the Coastal Adaptation Process flowchart - develop a local coastal planning policy.

     

The City wrote to the State Goverment seeking funding support for CHRMAP. We have received a formal response from the Premier, Hon Mark McGowan MLA.

 

Geraldton Geophysical and Geotechnical Investigations: Analysis of Coastal Erosion for the Northern Beaches

The results of the geophysical investigations of the northern beaches shoreline has been completed.  Read the report here

Coastal Monitoring

Coastal monitoring at Drummond Cove has begun and will continue into the future so that the City can understand the effectiveness of the two Geotextile Sand Container (GSC) groynes installed at the Whitehill Road foreshore north of the John Batten Community Hall in December 2018.

Sunset Beach Coastal Adaptation Works

In mid October 2019, construction of a 40m low-crest Geotextile Sand Container (GSC) groyne and 50m long low-crest GSC revetment began on the Sunset Beach Foreshore at Triton Place to mitigate coastal erosion. Read more on the project here

Local Coastal Planning Policy

A key component of the CHRMAP Report was the identification of long term adaptation pathways for 12 Coastal Management Units (CMUs) along the developed Geraldton coastline. The Geraldton CHRMAP is currently being used to inform the development of local coastal planning policies.

What's the Geraldton CHRMAP Report all about?

The Report presents the findings from the community consultation, the coastal hazard risk assessment that has already been completed and identifies and recommends adaptation pathways and management options that the City and other stakeholders can pursue to address the risks for coastal erosion and inundation. The report was developed using the State Government CHRMAP Guidelines. The report is divided into the following two parts:

The Geraldton CHRMAP Report was adopted by Council on 27 November 2018. A key component of the CHRMAP Report was the identification of long term adaptation pathways for 12 Coastal Management Units (CMUs) along the developed Geraldton coastline.

Part 1: Summary of the Coastal Hazard and Risk Assessment Report

Coastal Hazard and Risk Assessment Report presents the findings from the initial phases of the project based on the coastal hazard assessment and the community consultation phase that has been completed and reports on the following:

  • Potential risks arising from hazards in the coastal zone
  • Key coastal infrastructure and assets at risk within the coastal zone
  • Community and cultural values of the coastal zones

Part 1: Appendices to the Report (172 pages or 57MB) here

Part 2: Summary of the Coastal Adaptation Report

The Coastal Adaptation Report works through the outcomes of the risk assessment to develop coastal management and adaptation recommendations to mitigate risk to coastal assets.

The Report has divided the City's coastline from Drummond Cove to Cape Burney into 12 coastal management units. Coastal management and adaptation recommendations for each unit have been completed based on the adaptation hierarchy required for each unit along with a summary of the implementation actions including costs, timing and responsibilities.

The Report contains an implementation plan, which includes a planning framework for special control areas, plans for managing the erosion and inundation risks to properties in the special control areas, specific adaptation pathways and planning actions such as built form and design requirements, trigger points, title notifications and emergency evacuation planning.
