2.2    Topography
During the site walk-over, topographic features specific to the site were noted, and ground slopes were
recorded using a hand-held clinometer. As illustrated in Text Figure 5, the sites are located on a gently
sloping, westerly facing flank of an ancient sand dune, which crests about 25 m to the north-east.
12 Wyandra Street generally sloped to the west and 14 Wyandra Street sloped to the south. The natural
ground slopes across the properties were measured to generally range between about 2° to 5°. The south-
western corner of 12 Wyandra Street sloped from the pool to the boundary at about 8°.
