What earthworks & drainage work has to deal with here

Building in Modbury Heights
Modbury Heights earns its name — the suburb rolls across elevated ground with long views back toward the city, and its blocks carry the gentle-but-real slopes that come with that. The 1970s development wave terraced many yards with materials that are now half a century old, and replacing those tired walls and steps is the suburb's bread-and-butter outdoor work. Clay dominates, with pockets of construction-era fill that behave unpredictably under load. Owners here are practical renovators: durable surfaces, usable lawn areas and shade structures for the north-east's hot summer afternoons top most briefs.
Our approach in Modbury Heights starts with a level survey of where water enters, stalls and can legally leave. Connections to the legal point of discharge meet City of Tea Tree Gully 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.
