A planning-constraint profile of Northwood

state overlay data. This suburb is moderately constrained on the overlays we could measure - no flood mapping covers this suburb, so this is not a suburb-wide verdict.

Constraint readout
0.36 km² - this suburb is moderately 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 Northwood'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 Northwood
Two different things, kept apart on purpose. The ANEF contour is the planning instrument - a forecast published per airport that planning schemes use to control noise-sensitive development. Observed overflight is what a sampled aircraft-tracking feed actually recorded over the suburb - where aircraft flew, how low and how often.
Observed overflight - sampled 4 Sep to 2 Oct 2026
typical observed square 1 a day
Night movements: observed, lowest 1,000 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.
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.
