About the Project

The development of construction plans has been completed for new coastal protection structures within the section of the Cowes foreshore between Rose Avenue and Coghlan Road.

Proposed works include:

  • Construction of eight new timber groynes (i.e timber walls that extend into the sea at right angles to the shoreline): to replace the existing deteriorated groynes.
  • Sand re-nourishment to fill the new groyne fields.
  • Construction of a new 300 metre rock seawall: to replace the existing deteriorated vertical timber and timber/rock seawalls.

These works are being conducted to protect the foreshore, including the beach, dunes and public access from erosion. Over the past decade, erosion in the area has increased and the existing structures that were built to minimize erosion are now degraded. During storm surge events, waves overtop or pass through the seawalls, taking away important sand and coastal vegetation. The existing groynes are no longer fully functioning in their role to help maintain a sandy beach. The existing structures are also a risk to the safety of beach users.

Progress Update

Final works for the maintenance access track topping layer, stair access locations and public seating is anticipated to begin from 17 October for up to 2 weeks, weather permitting, contractor/supplier availability and any COVID-19 impacts.

Appropriate traffic and pedestrian control measures will be in place. This will be a construction zone and we appreciate that for your own safety and others that public access will be closed for up to a week whilst material is being delivered and placed.

  • Council has recently completed installation of eight (8) new timber groynes in December 2021 as Stage 1 of Cowes East Foreshore Restoration works. The new rock revetment works (Final Stage) are continuation of the foreshore restoration works.
  • The purpose of the rock revetment wall is to improve the beach amenity for public use, protect the existing shoreline from erosion by absorbing wave energy and provide significant protection to the beach and native vegetation.
  • Bass Coast Shire Council (BCSC) with funding from the Australian Government and assistance from Department of Environment, Land, Water and Planning (DELWP), will construct a 360 metre rock revetment wall at the Cowes East Foreshore between Rose Avenue and Coghlan Road to prevent foreshore erosion.
  • Provision of pedestrian and management vehicle access incorporating two beach ramp access points located at each end of the rock revetment and two beach access staircases.
  • The rock revetment is a permanent wall structure of rocks designed to protect and prevent long term damage from coastal erosion. Revetments are sloping structures comprised of various layers of large stones and geo-textiles placed on shorelines used to prevent shoreline loss.

The total project costs for the construction of eight new timber groynes and 300 metre rock seawall is $3.35 million. This includes the $720,147 for design and construction of the groynes and $2.64 million for design and construction of the seawall. We have received $1.1 million in grant funding from the Federal Government towards the groynes and seawall project.

The project will include, but is not limited to:

  • No native vegetation removal required during the works.
  • A small site shed will be placed on the east side of Rose Avenue at the beach end.
  • Appropriate traffic and pedestrian control measures will be implemented at the Cowes East foreshore area during these works. Significant truck and trailer movements will be experienced by landowners within the area. This will be a construction zone and for your own safety and others, there will be some beach access restrictions. Limited emergency access will be provided.
  • Our staff and contractor will notify nearby residents and user groups who may be impacted by these works. We appreciate that these works may present an inconvenience to some. We ask for your patience during these works.
  • The project will result in noise and vibration from heavy plant and machinery used for construction, including earthmoving equipment and use of trucks and cranes for removal or delivery of materials to site.

Before Photos

Waves overtopping or passing through the current deteriorated seawalls is resulting in the erosion of coastal land, further threatening assets.
