Flynn flood map & planning overlays

The schematic on this page is a Flynn flood map: the mapped flood overlays drawn over the suburb's terrain and street grid, covering about 14% of the suburb. Flood lines vary block to block, so for a specific property use the free interactive map - search any Flynn address and it shows the flood, zoning and bushfire mapping on the exact lot boundary.

About 14% of Flynn falls within a mapped flood overlay, against the council-wide suburb average of 9%. Flood overlays vary block to block, so whether a particular lot is affected needs a property-level check.

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

The dominant planning zone in Flynn is Farming Zone (FZ1), though the suburb also includes Farming Zone (FZ) and Special Use Zone (SUZ1). Zoning sets what you can build and do on a site, and can differ lot by lot.

Flynn has 7 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 380 surveyed parcels in Flynn, the median lot size is about 140,988 m². There are also 187 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.
