Truganina flood map & planning overlays

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

Flood mapping covers Truganina and none of the suburb falls within a mapped flood overlay (the council-wide suburb average is 4%). Flood overlays vary block to block, so whether a particular lot is affected needs a property-level check.

Around 64% of Truganina is mapped as bushfire-prone, compared with a Melton average of 68%. A bushfire-prone designation can trigger additional building requirements, so check the specific address.

The dominant planning zone in Truganina is Urban Growth Zone (UGZ9), though the suburb also includes Urban Growth Zone (UGZ) and Urban Growth Zone (UGZ10). Zoning sets what you can build and do on a site, and can differ lot by lot.
