Constraint readout
4.41 km² - this suburb is moderately constrained by planning overlays.

Aircraft noise and flight paths over Mordialloc
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 aircraft traffic is a separate question from the contour.
Inside an aircraft noise contour
23% of the suburb's land sits inside a published ANEF or airport-environs contour. Contours vary street by street, so whether a particular lot is inside one needs a property-level check.

- Whether the lot is in bushfire-prone mapping, and what that triggers for a build
- Whether the lot, or a neighbour, is one of the 25 heritage-listed places on record
- Which ANEF contour, if any, the lot sits in
- Walking distance to the nearest station
- A coverage disclosure: exactly which layers were, and were not, assessed

Is Mordialloc affected by aircraft noise?

What is the zoning in Mordialloc?
The dominant planning zone in Mordialloc is Neighbourhood Residential Zone (NRZ7), though the suburb also includes Industrial 1 Zone (IN1Z) and General Residential Zone (GRZ5). Zoning sets what you can build and do on a site, and can differ lot by lot.
