A planning-constraint profile of Acacia Ridge
(Brisbane City, QLD) - 8.61 km², mapped from live council and
state overlay data. This suburb is highly constrained.
Profile updated 7 November 2026.
Constraint readout
8.61 km² - this suburb is highly constrained by planning overlays.
Elevation hillshade with street names, clipped to Acacia Ridge's boundary, with the flood, bushfire and environmental overlays drawn on top. Amber hatching is the published aircraft noise (ANEF) contour. Magenta is where aircraft were observed in the sampled period, brightest below 3,000 ft.

Has Acacia Ridge flooded? Flood history and overland flow
Yes. Recorded flood mapping reaches into Acacia Ridge: 141 of the 4,087 properties we analysed (3.4%) sit at least partly inside a mapped historical flood extent (Historic Flood 1974: 140, February 2022: 73, January 2011: 73). The free address check says whether a given lot is inside one.

141 analysed properties intersect at least one mapped historical event extent.

Aircraft noise and flight paths over Acacia Ridge
The ANEF contour is a published planning forecast and observed overflight is what a sampled tracking feed recorded - neither describes any individual property.
Inside an aircraft noise contour
24% of the suburb's land sits inside a published ANEF or airport-environs contour. Contours vary street by street, so whether a particular lot is inside one needs a property-level check.
Highest contour present
Under AS 2021, land at ANEF 30 and above is generally unacceptable for new houses and most noise-sensitive uses. The contour is a forecast, not a measurement at any one house.
Contours held
- Brisbane City Plan Airport Environs ANEF
Observed overflight - sampled 4 Sep to 7 Nov 2026
typical observed square 17 a day
Night movements: observed, lowest 500 ft - night is sampled as often as day, but night traffic is light, so this is a floor and no rate can be put on it.
How this is measured
Traffic is sampled rather than watched continuously, so every figure is a floor: aircraft not captured between samples are not represented. Rates are per 500 m square - the busiest square in the suburb, not a count of flights over the suburb - and a square is only rated where enough traffic was seen to measure it. Altitudes are above mean sea level. Flight paths change with runway use, weather, season and airspace design. This is a record of observed traffic; it is not a noise contour and not a planning control.

Acacia Ridge planning - frequently asked
Is Acacia Ridge flood-prone?
About 22% of Acacia Ridge falls within a mapped flood overlay, against the council-wide suburb average of 31%. Across the suburb, 10% of the 4,087 properties we analysed carry some level of mapped flood risk, including 49 rated high risk or historically affected. Modelled flood depth, velocity and flood level are held for about 4,000 Acacia Ridge addresses, from published flood studies; the free check on the Flood Model Report page says whether a model reaches a given address.
Has Acacia Ridge flooded?
Yes. Recorded flood mapping reaches into Acacia Ridge: 141 of the 4,087 properties we analysed (3.4%) sit at least partly inside a mapped historical flood extent (Historic Flood 1974: 140, February 2022: 73, January 2011: 73). The free address check says whether a given lot is inside one.
Is Acacia Ridge bushfire-prone?
Around 3% of Acacia Ridge is mapped as bushfire-prone, compared with a Brisbane City average of 27%.
Is Acacia Ridge affected by aircraft noise?
About 24% of Acacia Ridge sits inside a published aircraft noise contour, and the highest contour present is ANEF 30 - under AS 2021, land above ANEF 25 is generally considered unacceptable for new houses, and 20-25 conditionally acceptable with noise attenuation. 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.
Is Acacia Ridge under a flight path?
Aircraft were observed below 3,000 ft over about 100% of Acacia Ridge, in the period sampled (4 Sep 2026 to 7 Nov 2026). The lowest measured aircraft was at 500 ft, with an average of 1,000 ft. At the busiest point in the suburb about 181 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.
