What the ground in Coombs tends to do
Coombs sits in the Molonglo Valley alongside the river reserve, on lots formed by recent civil earthworks. The finished result reads as tidy and straightforward, which is precisely the trap: the surface tells you very little about footing widths, fill depth or what runs beneath the paving.
Newer properties put paths, services and fencing directly against retained edges more often than older ones do, because the lots are efficiently used. That closeness is the main constraint on method. Before assuming a machine can work along the wall, check what would have to be lifted, protected or removed to make room for it.
Because the ground was placed rather than found, the depth and nature of fill under and behind a wall is a design input that cannot be observed. Where a wall is being added to an existing arrangement, establishing what the original earthworks did is more useful than measuring the visible face precisely.
Access, water and boundaries here
Access from John Gorton Drive, Fred Daly Avenue and Edgeworth Parade is good at the street. The question is how material reaches the wall without damaging finished paving or blocking a shared access route, which on these lots is a genuine constraint rather than a formality. Mark the pits and identify the apparent low point.
Proximity to the Molonglo River Reserve makes the discharge question worth taking seriously. Water leaving a property has to reach a lawful destination through the estate's stormwater system, and creating a new flow path towards a reserve edge is not a substitute for connecting into what is there.
Coombs properties can place paths, services and fencing directly beside retained edges. The clean appearance of a newer lot does not reveal footing width, fill depth or easements below the surface. Mark pits, identify the apparent low point and show how materials would reach the wall without damaging finished paving or blocking a shared access route.
Molonglo River Reserve, Coombs Shops, Charles Weston School locate the wider area, and Wright, Denman Prospect, Holder adjoin it. None of that substitutes for measurements taken on your own block.
