Flood Data Reliability Notes for Moreton Bay Region

Moreton Bay Council's polygon dataset identifies areas where 5% Annual Exceedance Probability flood data has limited reliability. The data, authored by moretonbaygis and last updated in March 2026, provides spatial definitions and reasons for this lower reliability.

Use Cases

• Map areas of limited flood data reliability using polygon spatial definitions for risk assessment planning
• Analyze the correlation between specific reasons for limited reliability and geographic locations within the Council area
• Integrate reliability notes with other flood layers to qualify confidence in flood hazard modeling outputs

Strengths

• Data is current, with a last update timestamp of March 2026
• Provides specific reliability assessments for a defined 5% AEP flood standard
• Offers multiple access formats including GeoJSON, KML, and CSV for flexibility

Limitations

• No quantitative row or feature count is provided to assess dataset scale
• Reliability is assessed only for a specific 5% AEP flood event, not other return periods
• Data scope is limited to the City of Moreton Bay's jurisdictional area
