Balmoral flood map & planning overlays

About 15% of Balmoral falls within a mapped flood overlay, against the council-wide suburb average of 31%. Across the suburb, 21% of the 2,235 properties we analysed carry some level of mapped flood risk, including 26 rated high risk or historically affected. Modelled flood depth, velocity and flood level are held for about 2,200 Balmoral addresses, from published flood studies; the free check on the Flood Model Report page says whether a model reaches a given address.

Yes. Recorded flood mapping reaches into Balmoral: 130 of the 2,235 properties we analysed (5.8%) sit at least partly inside a mapped historical flood extent (Historic Flood 1974: 130, January 2011: 55, February 2022: 30). The free address check says whether a given lot is inside one.

Bushfire mapping covers Balmoral and little to none of it is mapped as bushfire-prone (the Brisbane City average is 27%).

About 14% of Balmoral sits inside a published aircraft noise contour, and the highest contour present is ANEF 20 - under AS 2021, land between ANEF 20 and 25 is conditionally acceptable for houses, usually with noise attenuation in the build. ANEF contours are forecasts published per airport and used to control noise-sensitive development; they are not a measurement at any one house, and a property can sit under a flight path and outside every contour.

Aircraft were observed below 3,000 ft over about 92% of Balmoral, and over about 100% at any altitude up to 10,000 ft, in the period sampled (4 Sep 2026 to 7 Nov 2026). The lowest measured aircraft was at 1,000 ft, with an average of 2,000 ft. At the busiest point in the suburb about 112 aircraft a day were recorded passing over one 500 m square. Traffic is sampled rather than watched continuously and flight paths change with runway use, weather and season; the ANEF contour is the planning instrument.
