- Model potential damage from natural events based on the graduated hazard zoning.
- Inform regulatory zoning decisions for areas protected by structures, as they are considered subject to hazard.
- Identify areas of 'no or insignificant hazard' for development planning.
Strengths
- Data is based on a formal hazard study and risk analysis for the Risk Prevention Plan (RPP).
- Hazard zones are described as 'developed data' synthesized from multiple calculated, modelled, or observed sources.
- Includes areas protected by structures, which are specifically represented as subject to hazard.
