Wyan zoning & planning overlays

A planning-constraint profile of Wyan (Richmond Valley, NSW) - 76.27 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 3 October 2026.

Elevation hillshade with street names, clipped to Wyan'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 Wyan

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.

Across its 76.27 km², Wyan 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 8 heritage-listed sites on record, and the dominant land-use zone is Primary Production. The median lot measures about 375,055 m² across 124 parcels.

Wyan planning - frequently asked

Is Wyan flood-prone?

We don't yet hold flood mapping covering Wyan, 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. Richmond Valley is the authority to check for flood mapping in this area.

Is Wyan bushfire-prone?

Around 100% of Wyan is mapped as bushfire-prone, compared with a Richmond Valley average of 97%.

Is Wyan under a flight path?

Aircraft were observed over about 5% of Wyan 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.
