What one address lookup returns

• 01Planning: the statutory zone and the overlays held for that state, each with its scheme code, source layer and publishing state. Which states each category is held for is stated in every response.
• 02Development history: applications on the parcel and within 300 m, each linking back to the council record it came from.
• 03Hazards: flood, bushfire and contamination hits with the source properties, plus modelled 1% AEP water depth in metres where an official study raster covers the address, and Newcastle H1-H6 hazard class where that is what the source publishes. Hazard class is kept distinct from depth.
• 04Scores with their inputs: the 8 property scores plus a standalone aircraft noise component. Noise, for one, returns the dominant source, the per-facade breakdown, and the rail route or the road segment class and distance behind the figure, not just a number.
• 05A coverage status wherever a component cannot be assessed, so missing data is never presented as zero risk.

Flood depth specifically: the current library is 55 production rasters covering 48 Brisbane catchments and seven NSW study areas, so most addresses get the other flood evidence without a modelled depth. Coverage varies by component and is stated in every response.
