A third of Virginia's zoned land is industry, most of it council's heaviest precinct: 48.50 hectares of General industry C, roughly 60% of all such land across the twelve localities this noise-fence set covers, against Geebung's 13.48 hectares, Banyo's 10.37, Northgate's 7.82 and none in the other eight. Council publishes what that precinct is for: General industry C is intended for high impact activities that may produce more emissions, including noise, and needs greater separation from residential and other sensitive land uses. In Virginia the ground already does that separating.
Virginia's biggest single zone line is 2,957 metres where industry meets specialised centre land — large format retail and mixed industry and business — the longest of its type across these twelve localities by more than sevenfold, Kedron's 386 metres next and everywhere else zero. Neither party on that line is a household, and what a barrier along it is being asked to do follows from that.
Where housing and industry would otherwise meet, more than 30 metres of other land stands between them at every point. A shared works boundary has no such distance, and the barrier does all of it. The Department of Transport and Main Roads publishes what that takes: the line of sight between source and receiver interrupted fully rather than narrowed, a screen carrying enough mass that sound does not pass through the material, and nothing left open along the run. RYNO's own account of its approach sits alongside that rather than above it: dense materials and quality framing, specified for mass on a line between two businesses rather than two households — a stated method, not a measured result.
> The premises types described on this page — warehouses and distribution premises, factories and workshops, storage and yard areas, large format retail frontages, and the detached houses that make up almost all of the residential holdings — describe the kind of ground fencing work happens on in Virginia. Not one of them is a job RYNO has carried out, quoted or been engaged on here, and no site, business or facility is named on this page for that reason.
