Implementing HAZUS-MH in Pre-Disaster Mitigation David Slayter, R.G. County of Yuba Office of Emergency Services
What is HAZUS-MH? (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
HAZUS-MH Capabilities • Estimates direct physical damage to: • Buildings and their contents • Essential facilities • Bridges and pipelines • Induced damage • Debris generation
HAZUS-MH Capabilities • Direct Losses • Cost of repairs or replacement • Income loss • Agricultural losses • Indirect Losses • Supply shortages • Sales declines
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
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

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
Hazard Scenarios • Flood • Specific Return Intervals • Specific Discharge Frequency • Annualized Losses • Quick Look • Earthquake • Simulate user defined, historic, or probabilistic events
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)
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 • Functionality assessment (yes/no) • Vehicles and agriculture losses • Shelter requirements
Example HAZUS-MH Output List of schools from HAZUS-MH versus Yuba County GIS m HAZUS fire stations µ Volunteer and City Fire Departments F CDF facilities
Example HAZUS-MH Output Number of students enrolled K-12 Household Income Distribution Wheatland ($ in Thousands) Children Less Than 16 years old (each dot = 3 children) Ethnic Distribution as % Pop. (portion east Marysville)
Example HAZUS-MH Output Building types
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.
