River Levee Restoration, Burraga Island, Terara
Terara, NSW
Overview
BEEP was engaged by Public Works to undertake critical levee restoration works along the Shoalhaven River at Terara. The project addressed extensive flood damage across multiple Category 2 levee segments, focusing on structural remediation, erosion control, and compliance with modern design standards.
Over 840 lineal metres of levee was rebuilt across 12 dispersed sites in a challenging environment — with ferry-only access to Burraga Island, proximity to sensitive mangrove zones, and limited construction corridors — requiring careful sequencing and environmental oversight.

Summary
Delivered over 16 weeks with delays due to weather, the Terara River Levee Restoration project was completed safely, to design, and in full compliance with environmental regulations.
The works restored 840 lineal metres of levee across 12 sites using over 875m³ of armour rock and extensive engineered fill. BEEP’s adaptive approach, environmental stewardship, and logistical planning ensured this complex riverside project improved both flood resilience and ecological integrity for the local community.
