Coastal Construction Projects
|Timing:||July 2018 - July 2019|
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.
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.
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.
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.
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 expected to begin in August 2019 pending weather conditions and contractor availability.
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 Cape Paterson-Inverloch Road. Each of these areas have experienced over 33 metres of coastline retreat since 2012, with the SLSC building currently located 16 metres from the face of the dune and Cape Paterson-Inverloch Road within six metres of the eroding edge.
A working group composing DELWP, Bass Coast Shire, Parks Victoria, Regional Roads Victoria 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. Revegetation is planned to occur in spring 2019.
For further information, please see the latest community update.
Sand management in Loch Sport is currently underway for sections of beach along Lake Street, Victoria Street and The Boulevard, each of which have experienced significant erosion in recent years.
DELWP reached a funding agreement of $80,000 with Gippsland Ports for the project, who co-contributed $60,000. The works involve relocating sand to the specified areas in conjunction with the Gippsland Ports dredging program, which is focused on clearing sand near the Loch Sport Marina and The Boulevard’s boat ramp.
This project has progressed smoothly since commencing in June 2019, with the final section at The Boulevard expected to be completed before September 2019.
Coastal Public Access and Risk Projects
The Coastal Public Access and Risk Grants program was active in 2017/18 and 2018/19, providing financial assistance to Victorian coastal Crown land managers to reduce coastal risk and improve public access. The projects selected for the Gippsland region in 2018/19 are listed below.
More information can be found on the Coastal Public Access and Risk Grants web page.
Bullock Island: Pedestrian and vehicle separation and demarcation works on the island, with $16,800 of funding provided to East Gippsland Shire Council.
Cowes East: Foreshore erosion management planning for the entirety of Cowes East Beach. The grant of $25,000 was awarded to Bass Coast Shire Council.
Grantville: Works to reduce public risk from steel and rock debris adjacent to Malcolm Drive, as well as planning to improve erosion management. Funding of $40,000 was provided to the Grantville and District Foreshore Committee of Management.
