Ipswich Planning Scheme Overlay: Flood Regulation Lines and Urban Flow Paths

Four geospatial maps define flood-related development constraints for the Ipswich City Council area. The dataset includes an Adopted Flood Regulation Line, a 1 in 20 Development Line, Urban Catchment Flow Paths, and an Indicative map subject to further assessment. Ipswich City Council maintains this data, which was last updated on 2026-04-20.

Use Cases

• Identify land development constraints based on the Adopted Flood Regulation Line.
• Model urban stormwater flow and catchment management based on Urban Catchment Flow Paths.
• Assess flood risk for planning applications based on the 1 in 20 Development Line.
• Perform preliminary site analysis with the Indicative map, noting its requirement for further detailed assessment.

Strengths

• Contains four distinct, specialized map layers for detailed flood and catchment analysis.
• Data is updated on changes to the planning scheme, suggesting ongoing maintenance.
• Available under a permissive CC-BY-4.0 license for reuse.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and dataset size are unknown, which may limit suitability assessment.
• One map layer is described as 'Indicative and Subject to Further Detailed Assessment', indicating potential preliminary nature.
