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

The 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 eucalypt woodland and tall open-forest sclerophyll forest.

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.

Limitations To Development:
Urban Capability: high capability for urban development with appropriate foundation design.
