2013 STATE PLAN UPDATE RANKED HAZARDS
1 – Wildfire 2 – Flooding 3 – Earthquake 4 – Severe Summer Weather 5 – Severe Winter Weather6 – Communicable Disease
7 – Hazardous Material Incidents8 – Drought 9 – Landslide 10 – Dam Failure 11 – Terrorism 12 – Volcanic Eruption
Calculated Priority Risk Index
Probability, Magnitude/Severity, Warning Time, Duration
2013 STATE PDM PLANRISK ASSESSMENT
Use GIS to intersect structure data with hazard area Map hazards Parcel data from Montana Dept. Revenue Cadastral
Mapping Program for residential and commercial/agricultural/industrial properties
State critical facilities – spatially located as part of this project
Determine value and number of structures at risk
Population at risk Determine annual loss
Frequency = # events/period of record Magnitude = (damage/# events)/ total value of building
stock Annual Loss = Frequency x Magnitude x $Exposure in
Hazard Area
Statewide Risk Assessment
Risk Assessment Template Uses GIS to calculate loss estimates Provides local jurisdictions a standard
methodology to build upon and improve data presented in local plans.
Will produce standardized risk assessments and “apple to apple” comparison of hazard risks across the state.
2013 State PDM Plan contains analysis for all counties and incorporated communities
