Approved Plan - EXE230029

                Across the central portion of the site the site surface levels sloped down to the north at between about
                 25o and 40o (see Plate 2) to a gently sloping lower portion that extended northwards into neighbouring
                 bushland. The slope also extended north-west and south-east beyond the site boundaries.




                                Plate 2: steep slope crossing the central portion of the site (looing south-east)

                The steeper (south-eastern) portion of the central sloping area was overgrown and the “rock RW”
                 indicated on the survey plan was not visible. Upslope of the central sloping area a timber sleeper
                 retaining wall supported the relative flat yard area to the south. For more details on the retaining walls
                 see Section 4.3.4 below.



            4.3.2 Groundwater and Surface Drainage
                As noted in Section 4.2 above, no groundwater was encountered within the depth of the investigation.
                Based on the topographic setting of the site, surface run-off from the south not captured by the roads
                 stormwater drainage system would be directed down to the north and north-east through the site to the
                 bushland downslope.
                Locally, some run-off from the upper section of the site may be captured by drainage behind the retaining
                 walls within the upper yard area.



            4.3.3 Vegetation
                The site contained a number of medium to large sized trees which also occupied the neighbouring
                 properties. The northern portion of the neighbouring property to the east was grass covered.
                The bushland to the north extends to the lake foreshore and contained numerous trees (maximum height
                 about 20m).
                Based on our site observations there were occasional trees that were leaning and/or had curved bases
                 over the steeper section of the central sloping area of the site (see Plate 2 above).
