Brisbane City Plan 2014 Flood Overlay Areas for the Brisbane River

Brisbane City Council's open data platform provides a geospatial dataset delineating six flood planning area sub-categories for the Brisbane River. The data is part of the Flood overlay map (OM-006.1) within the Brisbane City Plan 2014, which is regularly updated. This feature class supports planning and development decisions by defining zones with different flood risk levels.

Use Cases

• Assess property development feasibility based on designated flood planning area sub-categories.
• Model flood risk exposure for infrastructure projects using the defined river flood zones.
• Inform land-use planning and policy by referencing the official City Plan 2014 overlay maps.

Strengths

• Data is officially maintained and regularly updated by Brisbane City Council.
• Defines six distinct flood planning area sub-categories (1 through 5, with 2 split into 'a' and 'b').
• Linked directly to the authoritative Brisbane City Plan 2014 document for interpretation.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and spatial extent are unknown, which may limit suitability assessment.
• Freshness should be verified as the last update timestamp is in the future (2026-06-28).
