Members of the public only have a few days left to provide feedback on the planned repairs to the Beach Rd sea wall in Akaroa.

Feedback on the repair proposal will be open until Wednesday, 27 November.

The planned project would see a new rock base (revetment) at the front of the existing wall to help protect the heritage structure and the pavement which has slumped in some areas.

Christchurch City Council capital delivery community manager Darren Moses says the waves have undermined the sea wall and scoured out mortar and sediment over the years.

“This has caused sections of the path behind the wall to slump, and holes to develop,” he said.

“We have filled these holes or fenced some sections to ensure pedestrian safety.

“We have used ground-penetrating radar to further assess the extent of the damage.

“The un-reinforced stone wall - built between 1901 and 1904 - has weathered the years. However, it needs repairs in preparation for the next 50-plus years.”

The proposed repair plan allows for a higher sea wall and increased rock base protection. The approach would also ensure easier maintenance and improved protection.

“By introducing a rock base on the seaward side, we can avoid any need for deep foreshore excavation and protect the heritage wall structure,” Mr Moses said.

Concrete below the wall will ensure greater stability, while shells and stones will help replicate and enhance the existing structure.

The Banks Peninsula Community Board will consider a final recommendation after the community's feedback. If approved, the repairs would be done over winter next year.
