Physiographic Region: Cumberland Lowlands
Geomorphic Process: Residual
Underlying Geology: Wianamatta Group
Soil Landscape: Blacktown

Landscape is gentle undulating rises on Wianamatta Group shale and Hawkesbury shale. Slopes are usually less than 5%, with rises to 30m. It has broad rounded crests and rises with gently inclined slopes. Cleared woodland and tall open forests.

Within the geological area there are remnants of narrow-leafed ironbark, forest red gum and grey box.

The soil is shallow to moderately deep. On crests, upper slopes and well drained areas they are red and brown podzolic soils. On lower slopes and areas of poor drainage they are yellow podzolic soils and soloths.

Limitations:
Moderately reactive highly plastic subsoil, low soil fertility, poor soil drainage.

The King street end of Newtown is also classified Developed Terrain which means extensive development has occured over the existing soil landscape to such an extent that it is no longer possible to get accurate data on that area.

Geology/Soil Type: Wianamatta Shale; clay soils.
Floristics: Turpentine-Ironbark Forest. Most was cleared for agriculture in the 19th century.
