Hillgrove zoning & planning overlays

A planning-constraint profile of Hillgrove (Armidale Regional, NSW) - 365.26 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 Hillgrove'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 Hillgrove

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.
