Coastal Construction Projects

Location: Lakes Entrance
Timing: Jul 2018 - March 2019
Project Details:

The works to replace a large segment of the Lakes Entrance bluestone seawall started in July, 2018.

The section to be replaced is approximately 216 metres in length, extending west from the local Ocean Rescue building to opposite the Commonwealth Bank.

This seawall had been subject to significant erosion and damage, with a partial collapse and resulting fissures to the footpath leading to an 80-metre stretch being closed off with temporary fencing for over a year, an inconvenience to hundreds of locals and tourists alike who traverse the coastline every day.

This seawall project is the result of a partnership with East Gippsland Shire, who contributed $400,000 in conjunction with the $1,300,000 put forward by DELWP. Albcon Pty Ltd have been contracted for the construction.

Location:Cowes East
Timing:June - August 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, each of which are in great condition and accumulating sand at a steady rate.

Sand renourishment is planned to follow before July, 2019, to reduce the impact of the groynes on down-drift areas and increase the quantity of sand in the system.

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

Location:Bullock Island
Project Details:

Gippsland Ports, with support from DELWP, are continuing their work at The Narrows on the northeast side of Bullock Island to construct a replacement seawall.

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. It will be replaced by a concrete panel structure.

DELWP has provided funding for this project, with $260,000 granted to Gippsland Ports for the construction of the seawall.

This will complete the replacement program for this section of seawall, which began construction in mid-September, with an estimated finish date before the end of November, 2018.

Location:San Remo
Timing:2016 -17
Project Details:

2016-17 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 for $400,000, with funding and oversight provided by DELWP with support from the San Remo Foreshore Committee of Management.

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 been undertaking comprehensive technical research to determine the best approach for all involved.

Sand management options have been proposed in a report by Water Technology, along with a site inspection/discussion by DELWP and Bass Coast Shire staff.

‘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.

This project is planned for 2019.

A sand renourishment is planned for the beach along Surf Parade, an area that has become more of a priority in 2018 after the strong, sustained southerlies and storms on July 6-8 and July 19-20.

These events threatened to undermine the local life-saving club’s observation tower but, fortunately, its design incorporates skids, allowing Bass Coast Shire Council staff to react quickly and move it back from the foreshore.

Additionally, Bunurong Road (which runs adjacent to the foreshore west of Wreck Creek) has seen inundation on several occasions in July, particularly near the boat ramp at Flat Rocks. Stretches of this road are now less than seven metres from the front of the dune, down from over 20 metres in December 2017, making this a very high-risk zone

Unfortunately, there has been a significant amount of sand and vegetation lost following these storms, leaving the beach inaccessible from many access points with steep cliffs up to seven metres high, and a two-metre drop from the main concrete landing (see picture below).

An options analysis is currently being undertaken by DELWP, with correspondence from Bass Coast Shire, Parks Victoria and VicRoads, all of whom have assets in this area.

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.

Sandy Point: Boardwalk extension works and an upgrade to the Roy Henderson path, with the grant of $25,500 awarded to Sandy Point Foreshore Committee of Management Inc.

Seaspray: Foreshore path and crossover from the Surf Club to the creek. Funding of $20,000 was provided to the Seaspray Reserve Committee of Management Inc.
