Heatherton flood map & planning overlays

The schematic on this page is a Heatherton flood map: the mapped flood overlays drawn over the suburb's terrain and street grid, covering about 9% of the suburb. Flood lines vary block to block, so for a specific property use the free interactive map - search any Heatherton address and it shows the flood, zoning and bushfire mapping on the exact lot boundary.

About 9% of Heatherton falls within a mapped flood overlay, against the council-wide suburb average of 19%. Flood overlays vary block to block, so whether a particular lot is affected needs a property-level check.

Bushfire mapping covers Heatherton and little to none of it is mapped as bushfire-prone (the Kingston average is 6%). Always confirm for the exact lot, as mapping can change.

About 16% of Heatherton sits inside a published aircraft noise contour. ANEF contours are forecasts published per airport and used to control noise-sensitive development; they are not a measurement at any one house, and a property can sit under a flight path and outside every contour.

The dominant planning zone in Heatherton is Green Wedge A Zone (GWAZ), though the suburb also includes Special Use Zone (SUZ1) and Green Wedge Zone (GWZ2). Zoning sets what you can build and do on a site, and can differ lot by lot.

Heatherton has 8 heritage-listed places on record. Heritage listing affects what you can alter or demolish, so confirm whether a specific property is listed or near a heritage place.

Across 1,400 surveyed parcels in Heatherton, the median lot size is about 437 m². There are also 1,240 registered easements mapped in the suburb - an easement can restrict where you can build, so always check the title and overlays for the specific lot.

There is no train station inside Heatherton itself. The suburb is served by 28 bus stops.

On the ABS SEIFA 2021 index of relative socio-economic advantage and disadvantage (IRSAD), Heatherton scores 1061 and sits in decile 9 of 10 nationally and decile 9 within Victoria - decile 1 being the most disadvantaged tenth of Australian suburbs and decile 10 the least. The national average score is 1000. SEIFA summarises income, education, occupation and housing across the whole suburb, so it describes the area, not any particular household in it.
