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
