Stage One works have been completed, with construction and installation of the new stormwater infrastructure now finalised.
Stage Two is scheduled to commence in April and be completed by September 2026. Completion of Stage Two will finalise the Stormwater Management System Upgrade – Bendalong Boat Harbour project.

About the project

The enhancement of the foreshore aims to provide the long-term resiliency from erosion caused by the storm events. Current erosion issues are leading to the loss of beach amenity and undermining of Council assets, with works to mitigate against both coastal and stormwater induced runoff. Stormwater network improvements seek to consolidate outlets discharging onto the foreshore and provide engineered scour protection to mitigate erosion from an increased pipe capacity. 

This project aims to:

  • Mitigate coastal and stormwater-induced erosion
  • Protect beach amenity and Council assets
  • Improve the stormwater network through outlet consolidation and scour protection
  • Enhance the foreshore through restoration works

Identified as a priority action in Council’s Open Coast and Jervis Bay Coastal Management Program (CMP) under actions BN.01 and BN.05, the project responds to risks of coastal erosion, runoff, and geotechnical instability.

 

Stage One Works (Late July to Late 2025)

These works are now complete. They included the construction and installation of new stormwater infrastructure.

 

Stage Two Works (Date TBC)

Works are scheduled to start in April 2026 and finish in September 2026. They’ll focus on natural enhancement of the foreshore.

 


Coastal Management Program (CMP) Context

The Shoalhaven Open Coast and Jervis Bay CMP has assessed the risk posed by the relevant coastal hazards within the Shoalhaven to identify priority management actions for coastal management within the CMP study area. This project has been identified and proposed following a rigorous assessment process that considered the financial viability, stakeholder acceptability, environmental benefits and feasibility of project delivery.
