Palmer Bridge Nose Creek Pathway Repairs & Riverbank Stabilization

Devcon restored site stability by repairing damaged public infrastructure following the flooding in 2013. The project entailed full creek-bank rehabilitation and armouring to reduce future erosion, along with reconstruction of a damaged pathway section and its handrail.

Crews stripped and regraded the site, removed unstable materials, and ensured proper disposal. We constructed a structurally secure bank profile using rock and suitable imported fill. After securing the bank, we reconstructed the permanent pathway and handrail to its original specifications. Finally, we installed erosion and sediment control mechanisms to protect the site during high-flow events, supporting long-term environmental stability.

Devcon process

1

Site mobilization and access control

Mobilized the site by diverting pedestrians, closing the pathway, and installing rig mats to reduce construction impacts.
2

Aquatic protection and isolation

Installed an in-stream site isolation chamber to capture and release fish within a distinct work area, eliminating risks to the surrounding aquatic environment.
3

Removal and reconstruction of infrastructure

Removed and disposed of the damaged pathway, handrail, and eroded creek banks. Installed a new pedestrian pathway and handrail.
4

Bank reconstruction and armouring

Supplied and placed heavy rock, clean fill, and engineered slope-containment baskets tied in with live willows to create a bio-engineered bank armour.
5

Landscaping and long term restoration

Re-established the site’s landscaping and vegetation using container plantings, hydroseeding, and mulch. Provided ongoing maintenance of the vegetation and grounds for two years.
