Desktop assessment informs future planning

Opus undertook a Preliminary Environmental Impact Assessment (PEIA) for a 22km stretch of highway in Western Australia.

We were engaged by Main Roads WA to assess a section of the MO31 Northam-Cranbrook Road. The assessment helped inform future planning for widening of the road for safety.

The PEIA involves a desktop assessment of the significance of proposed clearing within the road reserve, at the local and regional level. We looked for under-represented vegetation communities, threatened flora, fauna and ecological communities, waterways and wetlands, land degradation and heritage issues.

A desktop assessment and mapping of relevant environmental issues is currently being done. The potential impact of the proposed clearing for road widening and drainage infrastructure will also be assessed against the 10 clearing principles set out in Section 51O of the Environmental Protection Act 1986.
