The EES found that trenches are feasible at both Edithvale and Bonbeach, and that the level crossing works would not impact the Edithvale-Seaford Wetlands.

The EES also found that any potential changes to groundwater levels at Edithvale can be effectively managed through our design technique. At Bonbeach, changes to groundwater levels are relatively minor and unlikely to have a significant impact.

The projects are designed to minimise any potential effects on groundwater quality and the EES process found that our design technique means that the groundwater quality in Edithvale will not be impacted. At Bonbeach, the EES found that the risk of impacts to groundwater quality was extremely low.

Groundwater levels and quality will be monitored during, and for several years after construction to ensure no impacts arise.
