                residence (RHS).



                2.5     Vegetation
                The ground surface to the east of the existing residence was primarily covered by bare sands and scattered
                shrubs and mature trees. Dense understory was noted to the west, with scattered trees. Mature trees
                around the proposed development areas were noted to be relatively straight, exhibiting no obvious signs of
                tilting/leaning which could be attributed to slope instability. Some trees to the north-west of the residence
                were noted to be leaning, which could be an indicator of minor soil creep.

                2.6     Buildings and Other Structures
                The house is a two storey structure primarily of blockwork construction. Timber decking extended from the
                northern and western edges of the residence. The eastern side of the residence appeared to have settled
                previously, with cracking and vertical separation of blockwork noted (Ref. Text Figure 8). It appeared that
                this was related to poor/insufficient footing construction rather than global slope instability.

                Timber sleeper walls ranging up to about 1 m high were present along the western edge of the house and
                were in relatively good condition at the time of the assessment. A blockwork wall ranging up to about 1 m
                high was noted along the southern boundary, and was overturning. A timber retaining wall dilapidated by
                age was present to the north of the residence.
