RISK
Risk & Hazards
20-dimension composite score blending flood, bushfire, heritage, contamination, sea-level rise, flight noise, and other hazards. Higher = more constraints on development.
Use the Layers button on the map for basemap and overlays (zoning, heritage, flood, bushfire, cadastre).
Risk Score
Low Critical
Methodology: 20 hazard layers weighted by severity: flood (high), bushfire (high), contamination (high), heritage, TEC, mining title, sea-level rise, flight path noise, transmission, plus regional hazard multipliers. Tier thresholds: low <15, medium 15-30, high 30-45, critical 45+.
Auto-tier by zoom:
