Has Dugandan flooded? Flood history and overland flow

Yes. Recorded flood mapping reaches into Dugandan: 137 of the 467 properties we analysed (29.3%) sit at least partly inside a mapped historical flood extent (Defined Flood Event: 137). The free address check says whether a given lot is inside one.

Aircraft noise and flight paths over Dugandan

The ANEF contour is a published planning forecast and observed overflight is what a sampled tracking feed recorded - neither describes any individual property.

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.
