IT MAY not have anything to do with rock music, but the first layer of a huge rock bag seawall has been laid at the Pymble Avenue picnic and barbecue precinct in Inverloch.

Bass Coast Shire had contracted MAW Civil Marine Pty Ltd to undertake the Kyowa Rock Bag Seawall project, in order to protect the public assets from wave erosion. 
Works will see the construction of a 70-metre rock bag seawall, which is anticipated to be completed this month. 

According to the shire, the rock bag structure is designed to provide protection for a minimum of 10-years. 

“The contractor has laid the first layer of rock bags and the second layer of rock bags will be laid, after the sand backfill is completed behind the first layer of rock bags,” the shire stated.
“The sand will be transported from Point Norman.

“Due to the erosion, the area in front of the barbecue shelter has been eroded by 700 millimetres. This will be adjusted by adding a third layer of rock bags.”

The seawall was chosen as the preferred structure type, based on recommendation from the Department of Environment, Land, Water and Planning (DELWP).

DELWP has preference for a removable structure as opposed to a fixed seawall, due to the lack of sand near the project site.
