Deanside flood map & planning overlays

The schematic on this page is a Deanside flood map: the mapped flood overlays drawn over the suburb's terrain and street grid, covering about 5% of the suburb. Flood lines vary block to block, so for a specific property use the free interactive map - search any Deanside address and it shows the flood, zoning and bushfire mapping on the exact lot boundary.

About 5% of Deanside falls within a mapped flood overlay, against the council-wide suburb average of 4%. Flood overlays vary block to block, so whether a particular lot is affected needs a property-level check.

Around 82% of Deanside 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 Deanside is Urban Growth Zone (UGZ12), though the suburb also includes Rural Conservation Zone (RCZ) and Rural Conservation Zone (RCZ3). Zoning sets what you can build and do on a site, and can differ lot by lot.

Deanside has 10 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 7,278 surveyed parcels in Deanside, the median lot size is about 350 m². There are also 1,874 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.
