Number One zoning & planning overlays
A planning-constraint profile of Number One
(Mid-Coast, NSW) - 51.47 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.

Constraint readout
51.47 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 Number One's boundary, with the bushfire and environmental overlays drawn on top. No flood layer is drawn because we hold no flood mapping for this area.

Aircraft noise and flight paths over Number One
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 26 Sep 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.
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 Number One is zoned
Buying in Number One? The zoning, flood and bushfire lines on the section 10.7 certificate attached to the contract are mapped controls - see our s10.7 certificate guide.
Across its 51.47 km², Number One 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. There are 2 heritage-listed sites on record, and the dominant land-use zone is Primary Production. The median lot measures about 172,001 m² across 176 parcels.

Is Number One flood-prone?
We don't yet hold flood mapping covering Number One, 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. Mid-Coast is the authority to check for flood mapping in this area.
Is Number One bushfire-prone?
Around 100% of Number One is mapped as bushfire-prone, compared with a Mid-Coast average of 94%.
Is Number One under a flight path?
No aircraft were observed over Number One in the period sampled (4 Sep 2026 to 26 Sep 2026). Sampling is intermittent, so that is a floor rather than proof that none fly over. Traffic is sampled rather than watched continuously and flight paths change with runway use, weather and season; the ANEF contour is the planning instrument.
