 However, the lack of a cohesive infrastructure means that this cannot be considered an urban development.The civil parish covers 2,696 acres (1,091 hectares), and has long east-west and short north-south axes, stretching from the downs west of the River Avon to the watershed of the Avon and Till rivers in the east.Most of it is chalk downland, but there is some alluvial gravel deposited around the river.
