Coastal Adaptation Works - Underway - Potential - Completed

Climate change, rising sea levels and the effects of coastal erosion and inundation are impacting the City of Greater Geraldton.

The City has been continually adapting to climate change, rising sea level and coastal erosion for some time.

Some of these projects are small scale and provide short to medium term solutions whilst others are large and provide a long-term solution.

To better understand what is at risk and the options there are to adapt to these risks the City has prepared the Geraldton Coastal Hazard Risk Management and Adaptation Plan Report. More here

Potential Projects

Whitehill Road Third GSC Groyne

The Whitehill Road Foreshore in Drummond Cove has been identified by the WA State Government as an erosion hotspot.   The $5.5 billion WA Recovery Plan, has allocated $5 million to address erosion hotspots which includes Whitehill Road. As a result, the City has received $600,000 to construct a third Geotextile Sand Container (GSC) groyne at Whitehill Road in Drummond Cove and undertake sand nourishment of the foreshore. More here

Bluff Point Foreshore Coastal Adaptation Investigations

The Bluff Point coastline was identified in the Geraldton Coastal Hazard Risk Management and Adaptation Plan (CHRMAP) as being at risk from coastal erosion over the immediate planning time frame to 2030.

In early 2020, the City engaged M P Rogers and Associates to investigate and provide advice on potential coastal adaptation options for the Bluff Point foreshore. The report identified two locations at southern and northern ends of the foreshore that may require coastal adaptation works to help manage these coastal hazards.

The City is currently investigating the installation of a low-crest GSC groyne in the area north of Frederick Street to provide a no regrets coatal resilience to the northern section of the Bluff Point foreshore. The groyne would be similar to the ones installed at St Georges Beach, Sunset Beach and Drummond Cove. The groyne would also be complemented by sand nourishment to replenish the foreshore.

Whitehill Road Boat Launching Facility Concept Investigations

The shoreline fronting Whitehill Road is under erosive pressure and requires mitigation to reduce further coastal erosion.

One such adaptation pathway that has been investigated is the construction of a boat launching facility which would serve the dual function of providing protection to the vulnerable portion of the foreshore whilst providing a boat launch facility.

Completed Projects 

Sunset Beach Coastal Adaptation Works

The Sunset Beach Foreshore has been experiencing coastal erosion which has lead to the removal of City assets to prevent them from falling into the ocean.

The City engaged M P Rogers & Associates to investigate and provide advice on potential coastal adaptation options for Sunset Beach.

In Late November 2019, construction of a low-crest Geotextile Sand Container (GSC) groyne and revetment on the Sunset Beach Foreshore to mitigate coastal erosion was completed. A 40m low-crest GSC groyne and 50m long GSC revetment constructed at Triton Place will help retain an initial beach nourishment.  More here

Whitehill Road Coastal Adaptation Works

In July 2018, Council made the decision to construct two low-crest 40m long Geotextile Sand Container (GSC) groynes on the Drummond Cove Foreshore to mitigate coastal erosion at Whitehill Road.

These groynes, which extend across the beach and into the ocean, have been designed to retain sand at Whitehill Road and reduce reliance on temporary sand nourishment operations. Works on the project were completed in December 2018. More here

The Beresford Foreshore Coastal Protection and Enhancement Project

In January 2017, work began on one of the City's largest capital works projects to date.  Project works involved building a 100m long extension to the detached breakwater at Midalias Beach, a 45m long extension to the existing marina groyne and three shore based rock revetments between Mark Street and Mabel Street.  Protection woks were completed in later that year.  More here

The second stage, or Coastal Enhancement Works, which involved replacing amenities lost to coastal erosion over the years and landscaping works began in January 2018 and was completed in October 2018. More here

St Georges Beach Groyne

In mid 2016, the City installed a low level Geotextile Sand Container (GSC) groyne at the north end of the carpark to mitigate coastal erosion. These medium-terms works are complimented by the Mid West Ports Authority Northern Beaches Stabilisation Programme sand bypassing works.  More here
