Where the barrier stands is treated as already settled
On most boundaries it is settled: the run goes on the line, because the line is shared and nothing else is available. A Banyo street frontage is different in a dull, useful way — the ground behind the boundary is all inside the one holding, so the boundary is the outer limit of the options rather than the only one.
Position is exactly what the authority on this talks about. In its code of practice for managing transport noise, the Department of Transport and Main Roads sets out two things. A noise fence only does anything where the screen interrupts the whole of the sight line between what is making the sound and what is receiving it, and its efficiency depends on standing close to one or the other. The same code is equally plain about the limits. It cannot deal with isolated loud events; and topography, access requirements, sight distance, utility services, the presence of local streets and other sources in the area all sit on its list of things that can make a barrier technically infeasible. On a frontage with a street between the two sides, several of those are live at once.
So position gets quoted as a decision rather than an assumption — on the boundary, or set back inside the holding where the ground allows it — and RYNO will say where it thinks a run is not worth building at all. That is the road authority's account of what barriers do, not a claim about anything RYNO supplies, and this page attaches no number to it in any form.
