Western Australia EPA Referred Development Proposals with Spatial Boundaries

Western Australia's Department of Water and Environmental Regulation maintains a spatial dataset of significant development proposals referred to the EPA for environmental assessment. The dataset includes boundaries for proposals like mining, ports, and railways, with attributes completed by DWER Spatial Services. Data is updated regularly, with a last update recorded for March 2026.

Use Cases

• Analyze spatial overlap between proposal boundaries and conservation areas to assess environmental impact.
• Map the geographic distribution of referred development proposals like ports and railways across Western Australia.
• Use the spatial boundaries to assess proposals against other environmental datasets for cumulative impact studies.

Strengths

• Data is sourced from the authoritative Department of Water and Environmental Regulation.
• Spatial boundaries are provided for proposals, enabling geographic analysis.
• Dataset is actively maintained, with a last update in March 2026.

Limitations

• Not all proposals contain a spatial component, leading to incomplete boundary records.
• Boundary accuracy is dependent on the quality of data provided by the proponent, introducing potential inconsistencies.
