Slope Stability Assessment

slopes of the spur (where the gym is proposed) were at around 6°, with landscaping and the original
earthworks cut adjacent to the house steepened to about 10°.
Downslope of the existing residence a garden terrace had been formed by fill earthworks, which also
contained an in-ground swimming pool. The fill was estimated to be about 1.2 m height above natural
ground, and had been left battered at about 16° to 17°.
Ground slope angles were measured at the time of our site visit using a hand-held clinometer.
Site conditions at the time of our walk-over are shown in Text Figures 5 to 7 below, and on the following
page.
