A planning-constraint profile of Calder Park
(Brimbank, VIC) - 2.74 km², mapped from live council and
state overlay data. This suburb is highly constrained.
Profile updated 24 October 2026.
Constraint readout
2.74 km² - this suburb is highly constrained by planning overlays.
Elevation hillshade with street names, clipped to Calder Park'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.

Aircraft noise and flight paths over Calder Park
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
91% 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 between ANEF 25 and 30 is generally unacceptable for new houses; 20 to 25 is conditionally acceptable with noise attenuation. The contour is a forecast, not a measurement at any one house.

typical observed square 8 a day
Night movements: observed, lowest 2,500 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.

Calder Park planning - frequently asked
Is Calder Park flood-prone?
About 3% of Calder Park falls within a mapped flood overlay, against the council-wide suburb average of 6%.
Is Calder Park bushfire-prone?
Around 47% of Calder Park is mapped as bushfire-prone, compared with a Brimbank average of 15%.
Is Calder Park affected by aircraft noise?
About 91% of Calder Park sits inside a published aircraft noise contour, and the highest contour present is ANEF 25 - 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 Calder Park under a flight path?
Aircraft were observed below 3,000 ft over about 28% of Calder Park, and over about 72% at any altitude up to 10,000 ft, in the period sampled (4 Sep 2026 to 24 Oct 2026). The lowest measured aircraft was at 1,500 ft, with an average of 7,000 ft. At the busiest point in the suburb about 22 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 Calder Park?
The dominant planning zone in Calder Park is Special Use Zone (SUZ1), though the suburb also includes Industrial 3 Zone (IN3Z) and Transport Zone (TRZ2).
Does Calder Park have heritage-listed places?
