Coastal Construction Projects

Location: Inverloch
Timing:January 2020
Project Details:

Following severe winter storms in 2019 that caused considerable erosion at the Inverloch Surf Beach, the threshold to commission an emergency protection options analysis were breached, with DELWP procuring this work in October 2019 with support from the Inverloch Coastal Protection Working Group.

The consultant, Atkins Maritime Engineering Pty Ltd, investigated and designed a number of stabilising options to protect the foreshore in front of Bunurong Road and the Surf Life Saving Club. The analysis recommended the installation of a 70-metre sand-filled geotextile container wall at each site, to provide the most effective protection throughout winter while also benefitting from being safer, less expensive and removable compared to other options.

Funding of $450,000 was also announced for this work by Member for Bass Jordan Crugnale on behalf of the Hon. Lily D’Ambrosio, Minister for Energy, Environment and Climate Change, identifying the need for immediate protection. Additional funds of $700,000 for a Regional and Strategic Partnership in the area were also assigned at this time, which will involve a detailed investigation of the coastal processes and best protection options in the long-term through the completion of a Local Coastal Hazard Assessment among other projects.

Location: Lakes Entrance
Timing: July 2018 - July 2019
Project Details:

The construction works to replace a large segment of the Lakes Entrance bluestone seawall were completed in July 2019.

The existing seawall was a significant safety risk, with a partial collapse leading to the formation of large voids under the adjacent footpath that was being used by hundreds of locals and tourists every day.

The section to be replaced was approximately 216 metres in length, extending west from the local Ocean Rescue building to opposite the Commonwealth Bank, with the new concrete wall including a boardwalk, handrail and ramp access to the beach.

This seawall project was the result of a partnership with East Gippsland Shire, who contributed $452,000 in conjunction with the $1,300,000 put forward by DELWP. The works were completed by Albcon Pty Ltd.

Stage two of this project, replacing the seawall to the west of the Cunninghame Arm footbridge, is expected to take place in early 2020.

Location:Bullock Island
Timing:2018
Project Details:

Gippsland Ports, with support from DELWP, completed the seawall replacement work at The Narrows of Bullock Island in December 2018.

The previous masonry seawall was 120 metres long, had significant cracks in its face and large holes behind, and posed a high risk to the public. A concrete panel structure has been constructed in its place. 

DELWP provided $260,000 to Gippsland Ports for this project, finishing up the replacements works on the northeast side of Bullock Island that began in 2017.

Location:Cowes East
Timing:2018
Project Details:

The four timber groynes planned for construction along Cowes East Beach (adjacent to Lovers Walk) were completed in July 2018.

Of the four groynes, one is located west of Dunsmore Road and three to its east, with the older groynes (from the 1950s) in their place having also been removed as part of this work.

This project was tasked to Maw Civil Marine Pty Ltd, the contractor responsible for the previous three timber groynes constructed in 2015 along the same beach.

The height of the beach profile at the base of the new groynes increased by over a metre between August and November 2018 (based on data from the Victorian Coastal Monitoring Program), highlighting the effectiveness of groynes in areas of significant longshore sand transport like Cowes.

This project was organised by DELWP and Bass Coast Shire, with an expenditure of $200,000.

Location:San Remo
Timing:2017
Project Details:

2017 saw the construction of a 30-metre rock revetment and the replacement of a 60-metre timber retaining wall south of the boat ramp in San Remo, providing a much higher level of protection than that of the existing, well-worn timber wall.

This revetment connects with the main 600-metre revetment that protects the southern foreshore, stabilising the earth near the pylon that lies behind, which is the primary source of power for Phillip Island.

This work was contracted to Australian Project Solutions Pty Ltd for $400,000, with funding and oversight provided by DELWP with support from the San Remo Foreshore Committee of Management.

Location:San Remo
Timing:2016
Project Details:

The sheet pile seawall at San Remo, with concrete capping, an innovative handrail and a new beach access ramp, was completed in 2016.

This replaced the masonry wall that resided previously, which was much too low and had partially collapsed, leaving the high-use assets and foreshore behind unprotected.

The San Remo foreshore is extremely popular for watching the pelican feeding, making this project a high priority in order to cater for the thousands of tourists visiting every year.

The sheet pile seawall was the result of extensive stakeholder consultation, and was completed using $440,000 of DELWP funding by SMC Marine Pty Ltd.

Sand Management Projects

Cowes sand management is planned for the western side of the Cowes jetty at Cowes Main Beach, a popular recreational area on Phillip Island.

The vegetation behind the beach, particularly on the eastern side, has been scoured significantly in the past 10 years, with the erosion scarp present leading to the addition of fences in the past few years, increasing the safety to beach users but lowering the aesthetic appeal.

To address this concern and help restore the amenity of the beach, DELWP and Bass Coast Shire have sought technical advice and organised the completion of comprehensive coastal processes studies to determine the best approach for all involved.

Sand management options have been proposed in a report by Water Technology, along with multiple site inspections and discussions by DELWP, Bass Coast Shire staff and coastal engineers.

‘Soft’ solutions, involving sand renourishment and vegetation initiatives, are the preferred options, as they are more likely to retain the beach amenity while also bringing natural, long-term protection to the area.

Project design got underway in February 2019, with the renourishment works successfully completed in November 2019 by Maw Civil Marine Pty Ltd.

A trial wet-sand fence was installed at two sites on the Inverloch Surf Beach in March 2019, a response to the severe erosion that occurred due to winter storms in 2018.

The sites chosen were the foreshore adjacent to both the Inverloch Surf Life Saving Club and Bunurong Road. Each of these areas have experienced over 35 metres of coastline retreat since 2012, with the SLSC building currently located ten metres from the face of the dune and Bunurong Road within six metres of the eroding edge.

A working group composing DELWP, Bass Coast Shire, Parks Victoria, Regional Roads Victoria, South Gippsland Water and West Gippsland Catchment Management Authority, all of whom have assets in this area, was formed in July 2018 to address the erosion issues. The trial wet-sand fencing project was proposed with near-unanimous support at a community drop-in session in December 2018.

Sand renourishment of approximately 2,000 cubic metres total was completed behind the fences at both sites in June 2019, extending over 100 metres at each location to cover nearby access points as well.

Following further storms throughout winter 2019, additional sand renourishment of approximately 4,000 cubic metres was completed by Bass Coast Shire Council during September 2019 to provide a buffer from further erosion.

Both the wet-sand fencing and sand renourishment works were completed by Maw Civil Marine Pty Ltd.

Sand management in Loch Sport was completed between June and September 2019 for sections of beach along Lake Street, Victoria Street and The Boulevard, each of which have experienced significant erosion in recent years.

The works involved relocating approximately 42,000 cubic metres of sand to the specified areas in conjunction with the Gippsland Ports dredging program, which was focused on clearing sand near the Loch Sport Marina and The Boulevard’s boat ramp.

DELWP reached a funding agreement of $80,000 with Gippsland Ports for the project, who co-contributed $60,000.
