C12 0 Flood Prone Hazard Areas Code: Hobart Flood Risk Model

Potential Flood areas for all Hobart catchments, modeled for the year 2100 under a 1% Annual Exceedance Probability scenario. The dataset covers major waterways like the Hobart, New Town, and Sandy Bay rivulets, as well as minor drainage lines. It is intended as a general planning guide and requires site-specific investigation for property-level accuracy.

Use Cases

• Preliminary development planning based on modeled flood extents.
• Long-term climate adaptation strategy for infrastructure located near waterways.
• Community flood risk awareness and education using general hazard maps.
• Informing site investigation requirements for properties within the modeled flood zones.

Strengths

• Provides a specific, modeled future scenario for the year 2100.
• Covers a defined geographic area including all major Hobart catchments and minor drainage lines.
• Published as open data by the authoritative local government source, City of Hobart.

Limitations

• Dataset size, row count, and specific column schema are unknown, limiting detailed analysis.
• The data is explicitly a general guide and contains disclaimers about potential errors, requiring field verification for any project reliance.
• Conflicting 'last updated' dates (2026-04-11 and 2026-03-25) create uncertainty about the most current version.
