Implementing HAZUS-MH in Pre-Disaster Mitigation David Slayter, R.G. County of Yuba Office of Emergency Services

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 Source: Federal Emergency Management Agency (www.fema.gov/hazus)

HAZUS-MH Capabilities Estimates direct physical damage to: Buildings and their contents Essential facilities Bridges and pipelines Induced damage Debris generation Source: Federal Emergency Management Agency (www.fema.gov/hazus)

HAZUS-MH Capabilities Direct Losses Cost of repairs or replacement Income loss Agricultural losses Indirect Losses Supply shortages Sales declines Source: Federal Emergency Management Agency (www.fema.gov/hazus)

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 Source: Federal Emergency Management Agency (www.fema.gov/hazus)

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 Source: Federal Emergency Management Agency (www.fema.gov/hazus)

HAZUS-MH Capabilities Direct Damage Induced Damage Direct Losses Indirect Losses  General Building Stock Essential Facilities High Potential Loss Facilities Transportation Systems Utility Systems Fire Following Hazardous Materials Release Debris Generation Cost of Repair Income Loss Crop Damage Casualties Shelter Needs Generic Output Earthquake Ground Shaking Ground Failure Flood Frequency Depth Discharge Velocity Hurricane Wind Pressure | Missile | Rain Supply Shortages Sales Decline Opportunity Costs Economic Loss Source: Federal Emergency Management Agency (www.fema.gov/hazus)

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 Source: Federal Emergency Management Agency (www.fema.gov/hazus)

Hazard Scenarios Flood Earthquake Specific Return Intervals Specific Discharge Frequency Annualized Losses Quick Look Earthquake Simulate user defined, historic, or probabilistic events Source: Federal Emergency Management Agency (www.fema.gov/hazus)

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) Source: Federal Emergency Management Agency (www.fema.gov/hazus)

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 Source: Federal Emergency Management Agency (www.fema.gov/hazus)

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.
