Open data
Suburb-level datasets Delora builds from open government data, free to download and reuse with attribution.
Each file below is a plain CSV at a stable URL, rebuilt from the same warehouse that produces the suburb pages. Every figure is derived from openly licensed government data, and each dataset names its sources, its licence, the date its data was read and how to cite it. There is no API and no sign-up.

You can copy, share and adapt these datasets, including commercially, under the Creative Commons Attribution 4.0 licence.

These are general information about areas, not advice about any property. Shares are for whole suburbs and do not tell you whether a control applies to a particular address; the official planning scheme decides that. Found a problem? See corrections or get in touch.
Victorian suburbs: share of land under flood, bushfire and heritage overlays
For every Victorian suburb, the percentage of its land area covered by flood-related, bushfire and heritage planning overlays in the Victoria Planning Provisions.

Columns
| Column | Meaning |
|---|---|
sal_code | ABS Suburbs and Localities (SAL) code, ASGS Edition 3. |
suburb_name | ABS suburb or locality name. |
lga_name | Local government area (council) the suburb is assigned to. |
flood_overlay_pct | Percent of the suburb's land under a Land Subject to Inundation Overlay (LSIO), Special Building Overlay (SBO) or Floodway Overlay (FO), counted once where they overlap. 0 to 100, two decimals. |
bushfire_overlay_pct | Percent of the suburb's land under a Bushfire Management Overlay (BMO). 0 to 100, two decimals. |
heritage_overlay_pct | Percent of the suburb's land under a Heritage Overlay (HO). 0 to 100, two decimals. |
How it is built
Each overlay polygon in Vicmap Planning is intersected with the ABS suburb boundary in PostGIS; the union of the intersections is measured as geodesic area and divided by the suburb's area. A suburb with no overlay of a type shows 0.
Limits
A suburb-wide share says nothing about a particular lot: an overlay may cover only part of a street or the back of a block. Overlays are planning controls, not hazard models; a suburb with 0% flood overlay can still flood, and some councils map flood risk outside the planning scheme. Whether an overlay applies to an address is decided by the planning scheme: check it on VicPlan. Open VicPlan.

How it is built
Each zone polygon in Vicmap Planning is intersected with the ABS suburb boundary in PostGIS and measured as geodesic area over the suburb's area. One row per suburb and zone code. Zones covering less than 0.5% of a suburb are left out, so a suburb's shares can add to slightly under 100; roads in a Road Zone are included.
Limits
Shares describe the suburb as a whole, not any address. A zone's controls are set by the council's schedule to it, which this file does not restate. The zone that applies to a lot is decided by the planning scheme: check it on VicPlan. Open VicPlan.

How Delora checks a source's licence
A dataset is published here only when every source behind it has had its licence read on the publisher's own page and that licence allows redistribution of derived figures. Sources Delora holds whose terms do not allow this, or have not yet been read, are left out. See how Delora sources its data.
