Wonga Park flood map & planning overlays

The schematic on this page is a Wonga Park 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 Wonga Park address and it shows the flood, zoning and bushfire mapping on the exact lot boundary.

About 9% of Wonga Park falls within a mapped flood overlay, against the council-wide suburb average of 10%. Flood overlays vary block to block, so whether a particular lot is affected needs a property-level check.

Around 99% of Wonga Park is mapped as bushfire-prone, compared with a Manningham average of 56%. A bushfire-prone designation can trigger additional building requirements, so check the specific address.

The dominant planning zone in Wonga Park is Rural Conservation Zone (RCZ2), though the suburb also includes Rural Conservation Zone (RCZ5) and Public Conservation and Resource Zone (PCRZ). Zoning sets what you can build and do on a site, and can differ lot by lot.
