Benloch flood map & planning overlays

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

Flood mapping covers Benloch and none of the suburb falls within a mapped flood overlay (the council-wide suburb average is 2%). Flood overlays vary block to block, so whether a particular lot is affected needs a property-level check.

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

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

No heritage-listed places are on record within Benloch. Even so, it is worth confirming for an individual property before any works.

Across 141 surveyed parcels in Benloch, the median lot size is about 81,460 m². There are also 34 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.

At the 2021 Census Benloch had 138 usual residents, with a median age of 37 and an average household size of 2.6 people. The wider Romsey statistical area, which contains Benloch, went from 7,425 people in 2001 to 11,567 in 2025, up 56%. ABS publishes no annual population series for individual suburbs, so that trend describes the surrounding area rather than Benloch alone.

On the ABS SEIFA 2021 index of relative socio-economic advantage and disadvantage (IRSAD), Benloch scores 1056 and sits in decile 9 of 10 nationally and decile 9 within Victoria - decile 1 being the most disadvantaged tenth of Australian suburbs and decile 10 the least. The national average score is 1000. SEIFA summarises income, education, occupation and housing across the whole suburb, so it describes the area, not any particular household in it.

A Benloch planning report pulls every overlay - zoning, flood, bushfire, heritage, environmental and noise - that touches a single lot, on live council and state data. The interactive map preview is free; the full PDF report is $9.
