Has Kooralbyn flooded? Flood history and overland flow

Yes. Recorded flood mapping reaches into Kooralbyn: 144 of the 1,208 properties we analysed (11.9%) sit at least partly inside a mapped historical flood extent (Defined Flood Event: 144). The free address check says whether a given lot is inside one.

Aircraft noise and flight paths over Kooralbyn

Night movements: observed, lowest 2,000 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.
