2 SITE DESCRIPTION
The overall site is rural residential property that is legally described as Lot 5 on RP209009 which has a total plan area
of 8.07 ha. It is bound by Hayward Road to the north, Lake MacDonald to the west, and other rural residential
properties to the south and east. The property is approximately rectangular in plan shape, with the long axis parallel
to Hayward Road. Our investigation was focused toward the eastern boundary, and this area is hereinafter referred to
as the investigation area. An aerial image showing the overall site relative to Hayward Road and the surrounding
properties, with the investigation area highlighted, is shown below in Figure 1.
