Given the size of the Yanchep Rail Extension, minimising environmental and community impacts during construction and train operations is a key focus for METRONET and its delivery agencies.
Travelling through existing and planned developments, the majority of the 14.5 kilometre extension will be in a cutting to reduce noise and improve overall amenity for nearby residents and businesses. The rail alignment will travel through some Parks and Recreation sites and a Bush Forever area.
While every effort was made to avoid these areas, including careful consideration of alternative alignments, the undulating landscape, tight rail curve (not conforming to strict railway design standards) and impact on existing and future residents meant this was not viable.
Environmental and heritage considerations are a key priority for the Yanchep Rail Extension. Early studies undertaken by specialist consultants have identified the following environmental and heritage considerations:
- removal of native vegetation;
- waste management;
- loss of fauna habitat;
- disturbance of acid sulphate soils;
- dewatering and groundwater quality;
- existing soil and groundwater contamination;
- noise and vibration; and
- Aboriginal heritage.
These will continue to be assessed when the main contractor is appointed and in consultation during the approvals processes with the various regulatory bodies.
