2.3   Groundwater
No seepage or ‘springs’ were observed in the vicinity of the proposed shed site.

2.4   Surface Drainage
Natural surface drainage from the shed site follows surface contours towards the south-east. The natural
slopes appeared to be relatively well drained at the time of the walk-over. Surface water is expected to
drain rapidly from the natural slopes considering the moderate to steep gradients, relatively low permeability
clay soils and shallow depth to rock.
At the time of our visit, the previously formed building pad graded slightly to the north allowing surface water
to pond on the proposed shed pad. It appeared that a small diversion swale had been installed above the
northern end of the cut batter, channelling runoff east away from the proposed shed site down into the
existing dam.

2.5   Vegetation
At the time of the inspection, the proposed development area was free from vegetation with exposed phyllite
at the surface or gravel fill across the access tracks. Dense high grass, shrub vegetation and numerous
large mature trees were observed around the shed site. Most of the trees appeared to be relatively straight,
with no obvious signs of distorted growth which could be attributed to slope instability.
