Environmental Investigation, May 2014
Public Transport Authority Forrestfield Airport Link Environmental investigation May 2014 Executive summary GHD Pty Ltd (GHD) was commissioned by the Public Transport Authority (PTA) to conduct an environmental investigation for the proposed Forrestfield Airport Link (FAL) and associated infrastructure. The purpose of this investigation was to undertake an assessment of the major environmental constraints in the Study Area. The results and recommendations of this environmental investigation will provide advice on any next steps and environmental approvals which may be required. This report is subject to, and must be read in conjunction with, the limitations set out in sections 1.4, 3.1.1, 3.4 and the assumptions and qualifications contained throughout the Report. Key environmental constraints There were a number of potential environmental and ecological constraints within the Study Area. Given that the Project is still in the planning phase the PTA has the opportunity to review and refine the alignment to avoid, or minimise, impacts to these constraints. These constraints include: All vegetation associations and complexes mapped as occurring within the Study Area have less than 30 percent of their pre-European/pre-1750 extents remaining. However, the Study Area may be considered to be within a constrained area of the Swan Coastal Plain (EPA, 2006a). In this case, Beard (1979) vegetation association 1018 and all the Heddle et al. (1980) vegetation complexes are present at greater than 10 percent of their pre-European/pre-1750 extents remaining and would not, therefore, be considered critical assets. Vegetation associations 1001 (in the Cities of Bayswater and Belmont and the Shire of Kalamunda) and 1009 (in the City of Bayswater) are present at less than 10 percent of their pre-European extent remaining, and may, therefore, be considered critical assets.
