A planning-constraint profile of Derby
(Loddon, VIC) - 37.89 km², mapped from live council and
state overlay data. This suburb is highly constrained on the overlays we could measure - no flood mapping covers this suburb, so this is not a suburb-wide verdict.
Profile updated 24 October 2026.
Constraint readout
37.89 km² - this suburb is highly constrained on the overlays we could measure - no flood mapping covers this suburb, so this is not a suburb-wide verdict.
Elevation hillshade with street names, clipped to Derby's boundary, with the bushfire and environmental overlays drawn on top. Magenta is where aircraft were observed in the sampled period, brightest below 3,000 ft. No flood layer is drawn because we hold no flood mapping for this area.

Aircraft noise and flight paths over Derby
The ANEF contour is a published planning forecast and observed overflight is what a sampled tracking feed recorded - neither describes any individual property.
Observed overflight - sampled 4 Sep to 24 Oct 2026
Night movements: not established - night is sampled as often as day, but too few night flights have been seen here to conclude either way.
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.

How Derby is zoned
Selling in Derby? The zoning and planning overlays on this page are the controls a Section 32 vendor statement discloses.
Across its 37.89 km², Derby is highly constrained by the planning overlays we hold. We hold no flood mapping covering this suburb, so no flood figure is shown - that is a gap in our data, not an all-clear. Of what is mapped, 100% is flagged bushfire-prone. The dominant land-use zone is Farming Zone (FZ). The median lot measures about 311,574 m² across 137 parcels.

Derby planning - frequently asked
Is Derby flood-prone?
We don't yet hold flood mapping covering Derby, so this page can't say how much of the suburb is flood-affected - that is a gap in our data, not an indication that the suburb is free of flood risk. Loddon is the authority to check for flood mapping in this area.
Is Derby bushfire-prone?
Around 100% of Derby is mapped as bushfire-prone, compared with a Loddon average of 100%.
Is Derby under a flight path?
Aircraft were observed over about 8% of Derby in the period sampled, but only above 3,000 ft - the lowest measured was 6,500 ft. Traffic is sampled rather than watched continuously and flight paths change with runway use, weather and season; the ANEF contour is the planning instrument.
