A requirement of the contract is that BHFL obtain an Environmental Audit under Section 57AA of the Environment Protection Act in order to demonstrate that the land is suitable, in an environmental sense, for its intended end use. 2.0 SITE DESCRIPTION The site is located in former rail yards in an area situated between Footscray Road and Spencer Street Station as shown in Figure 1. The boundary of the site for audit purposes is the current lease boundary running outside the structure wall as shown in Figure 2. The boundary is likely to be brought in to the outside wall of the Stadium to allow maximum space for other developers within the precinct’. The site covers a total area of approximately 4.5 hectares with boundaries as shown in Figure 2. 2.1 Site History A requirement of the general Docklands Environmental Management Plan is that an archaeological investigation be carried out as part of the development of all areas of the Docklands. BHFL commissioned Mr. Gary Vines of the Living Museum of the West to carry out such a study. The program included: 0 background study of the history of the area; 0 a watching brief during initial earthworks on the site; and 0 the preparation of an archaeological assessment report. The report makes interesting reading and it helps explain the ground conditions encountered during the excavation of the site. The report has been included as Appendix A. The land on which the Stadium is being constructed is part of a large reclaimed area to the West of the City. The land was reclaimed starting in the mid 1800’s by filling with a variety of materials including silt dredged from the harbour, industrial waste and construction rubble. Very little archaeological evidence was found during the
