1 Survey of Hazus-MH: FEMA s Tool for Natural Hazard Loss Estimation

2 What is Hazus? Software tools and support system designed by FEMA for the purpose of providing communities with the means to identify and reduce risk from natural hazards Program elements include: Hazus-MH User Groups Education Program Other resources Available from FEMA free of charge (requires ArcGIS license) 2

3 Supported Hazards Hurricane Wind and storm surge Riverine and Coastal Floods Earthquakes 3

4 Loss Estimation Process Produce maps, tables, and reports Analyze social and economic impacts Considers what is at risk Identifies hazard Identify physical landscape 4

5 Output Physical Impacts Social Impacts Economic Impacts 5

6 Who is a Hazus User? Hazus is used by a variety of communities and organizations across the United States. Local and State Government Federal Agencies Educational institutions Private industry Others Considerable international interest 6

7 Inventory Components Aggregate Demographics General Building Stock broken down by type (how constructed) and occupancy (how used) Site Specific 7

8 Site Specific Inventory Represent discrete points of facilities and systems of inventory. Essential Facilities, High Potential Loss Facilities, User Defined Facility, Transportation Systems, Utility Systems, Hazardous Material Sites Provide site to site results versus an aggregated table of damages and losses. 8

9 Flood Model Overview

10 Scenario Options Return Period Discharge Value Flood Information Tool Quick Look Enhanced Quick Look User Provided Depth Grid HEC-RAS 10

11 Damage as % of replacement cost 0% 50% 100% Depth-Damage Curves Damage to buildings and infrastructure is estimated using depth-damage curves 0 ft 5 ft 10 ft 15 ft Depth of water 11

12 Results General Building Stock Results By Amount of Damage - occupancy, building type (sq. ft.) - by count By Dollar Losses - full and depreciated replacement value - building, content, and inventory losses - costs of relocation, wage, income, and rental losses - direct employee output losses and employment loss (days) 12

13 Results Essential facilities Building and content losses Functionality assessment (yes/no) Restoration time to 100% functionality Lifeline losses (for selected components) Losses to structures and equipment Functionality assessment (yes/no) 13

14 Results Vehicle Losses Agriculture Losses Shelter Requirements 14

15 Demonstration Hazus-MH Flood Model

16 Earthquake Model Overview

17 Scenario Options Deterministic Historical epicenter event Source event Arbitrary event Probabilistic User-supplied 17

18 Direct Physical Damage Structural and nonstructural damage estimates for buildings Damage state probability counts and losses 18

19 Utility Damage Pipeline and Facility Damages, Losses, and Functionality for Potable Water, Waste Water, Oil Systems and Natural Gas. Functionality at 1, 3, 7, 14, 30 and 90 days Number of households without Potable Water and Electricity 19

20 Transportation Damage Highway, Railway, Light Rail Bridge, Segment and Tunnel Losses, Damages and Functionality Bus, Port, and Ferry Facility Damage, Loss, and Functionality Airport Runway and Facility Damage, Loss and Functionality 20

21 Induced Physical Damage Debris Generation Wood and Masonry Steel and Concrete 21

22 Direct Economic Losses Building Losses (GBS) Structural Non-structural Content Business Inventory Business Interruption Wage Income Rental & Relocation Proprietor Lifelines Direct Cost of Repair 22

23 Social Losses - Casualties By severity level By time of day Severity 1 - No Hospitalizations Severity 2 Hospitalization Severity 3 Life Threatening Severity 4 - Fatality 23

24 Social Losses - Shelter Number of Displaced Households Temporary Housing Requirements 24

25 Demonstration Hazus-MH Earthquake Model

26 Hurricane Model Overview

27 Supported States Model includes 22 gulf and east coast states as well as Hawaii 27

28 Scenario Options Individual storms User-defined Historical Probabilistic 28

29 Direct Physical Damage Structural Damage for Buildings Damage State Probability Counts and Losses by Occupancy and Building Type 29

30 Direct Physical Damage Essential Facilities Loss of Use (Days) Damage State Probability 30

31 Debris Building Debris Wood and Masonry Steel and Concrete Tree Blowdown Tree Debris Eligible Tree Debris 31

32 Direct Economic Losses Building Losses Structural Non-structural Content Business Inventory Business Interruption Losses Wage Income Rental & Relocation Proprietor 32

33 Direct Social Losses Shelter Number of Displaced Households Temporary Housing Requirements 33

34 Demonstration Hazus-MH Hurricane Model

35 Integrating User Provided Data Non-Hazard Data Integration Tools Comprehensive Data Management System (CDMS) enables integration of locally developed non-hazard data CDMS validates that user data is compliant with Hazus requirements Hazard Data Integration User provided hazard maps (soils, elevation, liquefaction, etc.) can enhance the accuracy of loss estimations Each model includes tools for integrating user provided hazard maps Or..build your own tools??? 35

36 Success Stories Indiana and Georgia

37 Georgia 37

38 Indiana Data is centralized and standardized in two locations IndianaMAP (parcels) available for 90 of 92 counties Department of Local Government Finance (assessment data) Hazus-MH data has been enhanced for the entire state to rooftop level accuracy. Tools created to convert the centralized data to Hazus-MH required format 38

39 Next Steps Classroom Courses 9 classroom courses and 15 virtual courses User Groups LinkedIN FEMA Website 39
