Winter Valley flood map & planning overlays

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

Flood mapping covers Winter Valley and none of the suburb falls within a mapped flood overlay (the council-wide suburb average is 6%). Flood overlays vary block to block, so whether a particular lot is affected needs a property-level check.

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