The level crossings at Edithvale and Bonbeach are set to be removed by lowering the rail line into a trench. Because of their proximity to the internationally significant Edithvale-Seaford Wetlands, these projects are subject to an Environment Effects Statement (EES) process.
This EES is a detailed study into the potential impacts of the Edithvale and Bonbeach level crossings projects.
It describes potential effects of the Edithvale and Bonbeach level crossing removal projects on the environment and recommends ways to avoid, minimise or manage these impacts.
The EES focuses on three key areas that could be impacted by the projects:
The EES found that trenches are feasible at both Edithvale and Bonbeach. The EES found any potential impacts from the projects on the environment are considered to be minor and will be monitored throughout construction and for several years after completion.
The EES found that the level crossing works would not impact the Edithvale-Seaford Wetlands. This is because groundwater changes resulting from the project are highly unlikely to occur closer than one kilometre from the Edithvale wetlands.
Part of the EES focused on how to manage potential impacts the projects may have on groundwater levels and the ecosystems that depend on it.
It 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 level crossing removal projects are designed to minimise any potential effects on groundwater quality.
In Edithvale, our design technique means that the groundwater quality will not be impacted.
At Bonbeach, the EES found that the risk of impacts to groundwater quality was extremely low.
The EES, draft Planning Scheme Amendments (PSA) and all public submissions received on the EES will be considered by an independent Inquiry, appointed to provide expert advice to the Minister for Planning at public hearings, in June 2018.
