A planning-constraint profile of Kelvinhaugh
(Toowoomba Regional, QLD) - 42.2 km², mapped from live council and
state overlay data. This suburb is highly constrained.
Profile updated 7 November 2026.
Constraint readout
42.2 km² - this suburb is highly constrained by planning overlays.
Elevation hillshade with street names, clipped to Kelvinhaugh'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.

How common is mapped flood risk across Kelvinhaugh properties?
Counts of properties, not share of land, across 73 analysed Kelvinhaugh properties; no individual property result is identified.

From LayeredGeo's lot-risk engine: council flood overlays, historical flooding and terrain, resolved to each individual lot in Kelvinhaugh.
Has Kelvinhaugh flooded? Flood history and overland flow
Yes. Recorded flood mapping reaches into Kelvinhaugh: 1 of the 73 properties we analysed (1.4%) sit at least partly inside a mapped historical flood extent. The free address check says whether a given lot is inside one.

Aircraft noise and flight paths over Kelvinhaugh
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
16% 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

Observed overflight - sampled 4 Sep to 7 Nov 2026
typical observed square 1 a day
Night movements: observed, lowest 6,000 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.

Kelvinhaugh planning - frequently asked
Is Kelvinhaugh flood-prone?
About 73% of Kelvinhaugh falls within a mapped flood overlay, against the council-wide suburb average of 27%. Across the suburb, 6% of the 73 properties we analysed carry some level of mapped flood risk. Published flood models are held over parts of Kelvinhaugh; the free check on the Flood Model Report page says whether one reaches a given address.
Has Kelvinhaugh flooded?
Yes. Recorded flood mapping reaches into Kelvinhaugh: 1 of the 73 properties we analysed (1.4%) sit at least partly inside a mapped historical flood extent. The free address check says whether a given lot is inside one.
Is Kelvinhaugh bushfire-prone?
Around 10% of Kelvinhaugh is mapped as bushfire-prone, compared with a Toowoomba Regional average of 36%.
Is Kelvinhaugh affected by aircraft noise?
About 16% of Kelvinhaugh 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 Kelvinhaugh under a flight path?
Aircraft were observed below 3,000 ft over about 86% of Kelvinhaugh, and over about 99% 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 500 ft, with an average of 3,000 ft. At the busiest point in the suburb about 13 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.
What is the zoning in Kelvinhaugh?
The dominant planning zone in Kelvinhaugh is Rural, though the suburb also includes Specialised Centre and Unzoned.
Does Kelvinhaugh have heritage-listed places?
No heritage-listed places are on record within Kelvinhaugh.
Is Kelvinhaugh hilly or flat?
Kelvinhaugh is largely flat: the median ground slope is about 0%, and 1% of measured points sit on grades of 15% or steeper. Ground level runs from roughly 403 m to 460 m AHD across the suburb.
What is the typical lot size in Kelvinhaugh?
Across 58 surveyed parcels in Kelvinhaugh, the median lot size is about 749,134 m². There are also 5 registered easements mapped in the suburb.
