Where the overlay lands is almost entirely a question of how close a property is to the suburb's outer line, not to a road. Buffer the Stafford Heights boundary by 60 metres and 92.2 per cent of the mapped corridor is already inside that buffer; tighten the buffer to 30 metres and 57.7 per cent of it still is. That is a diagnostic an owner can use, because a parcel's position in the suburb is something they already know.
Council's holdings layer returns 2,815 cadastral holdings sitting majority-inside Stafford Heights, 2,779 of them on General residential zoned land. Seventy-five holdings in all, and 66 of the residential ones, have part of their parcel inside the mapped corridor. Roughly 97.6 per cent of the residential holdings have none of it anywhere on their land. For those owners the noise being weighed up is not corridor noise and the corridor is not the argument for their fence.
Council keeps a separate centreline layer for the roads this overlay is drawn from. Clipped to Stafford Heights it measures 0.0 metres — none of it runs inside the locality — and the nearest such centreline lies 11.4 metres beyond the locality polygon. The source is therefore across a line drawn between suburbs rather than at the end of a Stafford Heights street, which changes what a boundary walk has to establish and which end of the sound path an owner can actually do anything about.
Nothing local here is split between authorities. Brisbane City Council draws that overlay, and the overlay sits inside City Plan 2014, the planning scheme the same council administers across the locality. The second instrument is the building-approval rules, and at a Stafford Heights address those are Brisbane's. One name on the map and on the scheme, and nothing for a reader to work out about who holds what — which is the useful thing this locality offers, and the reason the rest of this page can be spent on the boundary instead of on the paperwork. It has an edge, and the edge is worth stating. The overlay is named after a part of the Queensland Development Code. What that part asks of a building sits outside this page's evidence, and nothing written here is a claim in either direction about it, or about any relationship between a fence and any part of it.
> Every figure on this page is a measurement across a locality, taken from Brisbane City Council's published data and the Census. It describes the ground Stafford Heights contains, not ground the business has worked on: RYNO has no job, project, client, photograph or site note on record anywhere in this locality.
