                  1.2 Site Characteristics
                  The site is approximately 0.5 hectares. It is on free-draining sandy soils (as described in
                  Section 1.6).

                  The rear, northern end of the site is at RL 34.1 m grading to RL 32.5 m at the southern
                  boundary, a grade of about 1.6%. A raised mount to the south east of the site rises to RL35
                  M. The lowest point of the site is at the south western corner, at RL 32.27 m.

                  It is currently vegetated with endemic dunal species, including Banksia spp. and
                  Xanthorrhoea spp.
