4.3.3 Vegetation
   The subject site included grass covered yard areas with some garden beds in the front yard and lining the
    north-western and south-eastern site boundaries which contained small to medium shrubs and some
    small trees.
   Beyond the north-eastern site boundary several large trees lined the south-western edge of the wetland
    area (see Plate 3) which comprised a thickly vegetated area containing shrubs and grasses.




                                  Plate 5: Spoonbill Street Median Strip.
   Some medium to large sized trees were present in the median strip to the south-west of the site (see
    Plate 5).
   All the trees described above had curved bases and/or were leaning over to the north-east, particularly
    those close to the north-eastern site boundary. However, based on the steepness of the localised slopes
    it is considered that the trees are growing towards the sunlight rather than indicating slope instability.



4.3.4 Buildings and Other Structures
   The subject site was occupied by a single storey timber clad house with a suspended floor. A car port was
    constructed on a flat building platform supported by concrete block retaining walls (maximum height
    about 0.8m). The southern portion of the front yard included flat grass covered terraces supported by
    gabion basket retaining walls (maximum 0.8m height).
   To the south-east, the neighbouring site contained a single storey timber house situated over the central
    section of the neighbouring site. The house was set-back approximately 2m from the common site
    boundary. Whilst observations were restricted, it appeared that the neighbouring front yard was
    supported by a low height timber sleeper retaining wall.
   To the north-west, the site contained a one and two storey brick and timber house over the central and
    south-eastern portion of the neighbouring site. The northern portion of the rear yard contained an
    inground pool. The house and pool were set-back at least approximately 3m from the common site
    boundary.
   The asphaltic concrete (AC) paved Spoonbill Street contained some minor cracking orientated parallel
    with the roadway which is interpreted to indicate localised weak pavement subgrade conditions and/or
    poorly constructed pavement rather than slope instability.
