Soil landscape The soil landscape broadly replicates the underlying geology whereby four soil landscapes underlie the study area: Lucas Heights: a residual soilscape, comprising moderately deep yellow podzolic (broad-leafed forest derived), yellow soloth (formed of saline materials), and yellow earth soils. It is characterised by its moderately reactive highly plastic subsoil and poor drainage Blacktown: a residual soilscape, comprising deep yellow podzolic soils, yellow brown, earth, red podzolic soils and structured loams. It is characterised by its moderately reactive highly plastic subsoil and poor drainage Deep Creek: a fluvial soilscape, comprising deep podzolic soils on well-drained terraces. Siliceous (silica derived) sands overlay the former floodplain with humus (decayed organic matter) podzols in low lying areas. It is characterised by an extreme erosional and sedimentation hazard. The soils also contain permanently high water tables Gymea: an erosional soilscape, comprising moderately deep yellow earth and earthy sands on gleyed (iron-rich) podzolic soil and yellow podzolic soils. It is characterised by its steep slopes, high erodability and high permeability. The one exception to the above is around Ultimo where the manmade fill has resulted in the presence of disturbed terrain. Generally, this ‘soil’ is characterised by turfed fill areas commonly capped with a sandy loam or compacted clay over fill and waste materials. These soils are characterised by a risk of mass movement and are generally impermeable, toxic and poorly drained. The majority of the proposal footprint is underlain by Gymea soils, which commonly occurs on Hawkesbury sandstone, with few exceptions as summarised in Table 6-52.

Acid sulphate soils Acid sulphate soils (ASS) are soils that contain iron sulphides, which produce sulphuric acid when exposed to oxygen in air. The majority of the proposal footprint is located over soils that have the lowest potential risk of containing ASS (class 5) (refer to Figure 6-6). Table 6-53 lists the exceptions.
