What earthworks & drainage work has to deal with here
01
Hidden stone in gravel fans
Augers hit stone without warning at the foot of the ranges.
What Rostrevor is built on
Gravelly fans and clay bands at the foot of Black Hill — augers ring on stone without warning.
On slopes, water arrives from above. Cut-off drains on the high side, ag-drains behind walls and controlled outlets protect the house and the neighbours below.
Building in Rostrevor
Rostrevor pushes right against Black Hill and Morialta's ridgelines, and its upper streets are as steep as suburban Adelaide gets. Yards here are commonly tiered two or three times, and the original owner-built retaining — random stone, railway sleepers, brick planters — is now failing in waves, making structural wall replacement the suburb's steady demand. The stony outwash ground gives excellent founding once you reach it, but reaching it means machinery and bits chosen for rock. Morialta's adjacency also brings bushfire overlays to the highest streets.
Our approach in Rostrevor starts with a level survey of where water enters, stalls and can legally leave. Connections to the legal point of discharge meet City of Campbelltown requirements, and surfaces are reinstated over trench lines.
Rainfall (Foothills): roughly 600–800 mm a year (approximate long-term averages at nearby Bureau of Meteorology stations). Higher winter rainfall means run-off from upslope blocks is as much a design issue as summer watering.
