Shaws Bay Eastern Arm Erosion Protection

Environmental Remediation

Synergy was contracted to remediate extensive shoreline erosion that had occurred along portions of a specific waterway within Shaw Bay. The works required reconstruction and repair of existing rock walls that had failed due to tidal impact and rock groyne construction into the waterways to protect existing beach reserve. As part of the reconstruction works native vegetation was planted to stabilise the remediation areas that extended across the constructed rock wall and groyne focus areas.

With support from the client an opportunity was recognised to provide recreational and amenity improvement for the site and as part of this Synergy were engaged to construct 1,500m2 of pedestrian concrete pathway, shower bays and seating pads. General environmental upgrade was also undertaken that included establishment of 6,000m2 of turf and health and safety management of existing mature vegetation.

This project required the management of protected seagrass and salt marsh vegetation that was located within the intertidal works area. Protection of these sensitive ecological communities was paramount during the repair and upgrade to the rock walls and groynes. Erosion mitigation was installed that included the use of fixed silt booms, temporary rock diversion and no-go zones.

During the works it was identified that an existing site storm water system provided habitat for large protected rock cod fish. As the remediation and construction works occurred Synergy ensured the protection of these fish from being exposed to any silt generation and provided them free movement into the waterways by installing silt booms to guide in and out of the intertidal habitat. Further stabilisation of the habitat was also completed that included installation of concrete curtain and dedicated rock groyne placement.
