A review of environmental factors (REF) is a document that is prepared to demonstrate due diligence and comply with the requirements of the Environmental Planning & Assessment Act (1979). Typically, it applies to construction activities which do not require consent under the act. Instead, the proponent (in this case, the City of Parramatta) must clearly demonstrate it has identified all environmental impacts of the proposal, along with mitigation measures to minimise those impacts. The REF needs to be appropriate to the nature and scale of the proposal, and often draws on specialist studies to reach a conclusion on the nature and extent of impacts and mitigations.
An independent planner was commissioned to prepare this REF. The planner integrated the advice and findings of all specialist designers and engineers who prepared the design for the upgrade and associated works. This was supplemented by reports commissioned for the project from heritage specialists, archaeologists and ecologists.
The City of Parramatta is committed to implementing the mitigations and safeguards identified in the REF.
