Derrinal flood map & planning overlays

The schematic on this page is a Derrinal flood map: the mapped flood overlays drawn over the suburb's terrain and street grid, covering about 1% of the suburb. Flood lines vary block to block, so for a specific property use the free interactive map - search any Derrinal address and it shows the flood, zoning and bushfire mapping on the exact lot boundary.

About 1% of Derrinal falls within a mapped flood overlay, against the council-wide suburb average of 8%. Flood overlays vary block to block, so whether a particular lot is affected needs a property-level check.

Around 100% of Derrinal is mapped as bushfire-prone, compared with a Greater Bendigo average of 100%. A bushfire-prone designation can trigger additional building requirements, so check the specific address.

The dominant planning zone in Derrinal is Rural Conservation Zone (RCZ1), though the suburb also includes Public Conservation and Resource Zone (PCRZ) and Transport Zone (TRZ2). Zoning sets what you can build and do on a site, and can differ lot by lot.
