Powelltown flood map & planning overlays

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

Flood mapping covers Powelltown and none of the suburb falls within a mapped flood overlay (the council-wide suburb average is 5%). Flood overlays vary block to block, so whether a particular lot is affected needs a property-level check.

Around 100% of Powelltown is mapped as bushfire-prone, compared with a Yarra Ranges average of 97%. A bushfire-prone designation can trigger additional building requirements, so check the specific address.

The dominant planning zone in Powelltown is Public Conservation and Resource Zone (PCRZ), though the suburb also includes Green Wedge Zone (GWZ5) and Rural Conservation Zone (RCZ3). Zoning sets what you can build and do on a site, and can differ lot by lot.

Powelltown has 9 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 157 surveyed parcels in Powelltown, the median lot size is about 1,301 m². There are also 23 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.
