2. What is HAZUS-MH? Geographic Information System (GIS)-based software
(Hazards U.S. – Multi-Hazard)
Geographic Information System (GIS)-based software
Calculates estimated loss due to physical damage from earthquakes, floods, and wind (does not estimate losses due to fire)
Knowing potential losses helps toward:
Improved infrastructure to protect the public and reduce economic losses
Improved planning decision-making

3. HAZUS-MH Capabilities
Estimates direct physical damage to:
Buildings and their contents
Essential facilities
Bridges and pipelines
Induced damage
Debris generation

4. HAZUS-MH Capabilities
Direct Losses
Cost of repairs or replacement
Income loss
Agricultural losses
Indirect Losses
Supply shortages
Sales declines

5. HAZUS-MH Capabilities
The estimation is calculated by spatial analysis methods using:
Nationwide databases
Census 2000
Dun & Bradstreet data of commercial businesses
Nationally-standardized loss estimation and risk assessment methodology
National Institute of Building Sciences (NIBS)-developed loss estimation methods

6. HAZUS-MH Capabilities
Nationwide Databases:
Demographics – Population, Employment, Housing
Building Stock – Residential, Commercial, Industrial
Essential Facilities – Hospitals, Schools, Police Stations, Fire Stations
Transportation – Highways, Bridges, Railways, Tunnels, Airports, Ports and Harbors, Ferry Facilities
Utilities – Waste Water, Potable Water, Oil, Gas, Electric Power, Communication Facilities
High Potential Loss Facilities – Dams and Levees, Nuclear Facilities, Hazardous Material Sites, Military Installations

8. Benefits HAZUS-MH allows the user to:
IDENTIFY vulnerable areas that may require planning considerations
ASSESS level of readiness and preparedness to deal with a disaster before it occurs
ESTIMATE potential losses from specific hazard events (before or after a disaster hits)
DECIDE how to allocate resources for most effective and efficient response and recovery
PRIORITIZE mitigation measures that need to be implemented to reduce future losses

10. EXAMPLE: HAZUS-MH Flood Model Results
Hazard maps
Flood depth
Building losses
By occupancy and by building type
By full replacement value and depreciated replacement value
Building, content, and inventory losses
Costs of relocation, wage and income losses, rental income loss
Direct employee output losses and employment loss (days)

11. EXAMPLE: HAZUS-MH Flood Model Results
Essential facilities
Building and content losses
Functionality assessment (yes/no)
Restoration time to 100% functionality
Lifeline losses
Losses to structures and equipment
Vehicles and agriculture losses
Shelter requirements

15. Summary
HAZUS-MH will provide the PDM Plan FEMA-approved risk assessment evaluation.
Results will be used to guide mitigation opportunities for at-risk areas.
Motivation for continued maintenance and expansion of Yuba County GIS inventories.
