1 Overview of HAZUS December 6, 2011

2 What is HAZUS? Risk assessment tool for analyzing potential losses from hurricane, flood, and earthquake Uses current scientific and engineering concepts in a GIS to estimate hazard related damages HAZUS is only an estimation tool for losses due to a disaster and could be significantly different from an actual event 2

3 Loss Estimate Process Produce maps, tables, reports Analyze social and economic impacts Consider what is at risk Identify hazard Identify physical 3

4 HAZUS Analysis Levels 4

5 How does HAZUS calculate damages for Flood? HAZUS Flood uses depth/damage curves developed by USACE and other agencies to determine damage to a building based on the flood depth HAZUS calculates Losses to buildings and their content and inventory (businesses) value Debris generation from building damages Displaced population (used to identify evacuation routes and shelter requirements) Agriculture Losses due to flooding Damage to essential facilities (police, fire, medical, schools, and EOC s) Damage to transportation facilities (ports, ferry facilities etc.) 5

6 HAZUS Inventory Module Aggregate Information General Building Stock Demographics Site-specific Information Essential Facilities High Potential Loss Facilities User Defined Structures Hazardous Sites Transportation Lifelines Utility Systems 6

7 HAZUS Inputs for Flood Level 1 Analysis (For areas with no existing flood data) Single Discharge or return period (i.e. 100 year discharge is 13,500 cfs or 1% change return period) Elevation data (DEM, LiDAR etc.) *Needed for all analysis levels Out of the box HAZUS data Levee 2 Analysis (Ideal analysis level) Flood Information tool (generates depth grid from water surface elevation and elevation data. *water surface elevation available through flood insurance study) Depth grid generated outside of HAZUS using HEC-RAS, FLO-2D etc. HEC-RAS depth grids are directly input into HAZUS. User update general building stock, essential facilities, transportation, etc. Level 3 Analysis (Engineering specific data) Updated engineering building data Update depth/damage curves 7

User update general building stock, essential facilities, transportation, etc. Level 3 Analysis (Engineering specific data) Updated engineering building data Update depth/damage curves 8

9 Where do I find data for use in HAZUS? Local parcel/assessors data can be input into HAZUS. The following data is required for each parcel: Building replacement value (typically use building improvement value). *Assessed values should not be used. Building square footage Building type (residential, commercial, industrial etc. ) Building count (per parcel) Elevation data (DEM s, LiDAR etc.) can be found from various sources such as: National USGS Seamless Data Warehouse ( FEMA Regional Office Regional Puget Sound LiDAR Consortium ( Oregon LiDAR Consortium ( Idaho LiDAR Consortium ( Local Datasets 9

10 Where do I find data for use in HAZUS? (Con t) FEMA Flood Insurance Studies Discharges and frequencies FEMA Flood Insurance Studies Hydrologic and Hydraulic Flood Models generate water surface elevations (*available where a detailed flood study was preformed) Water surface and elevation data can be used to generate a flood depth grid Depth grids can be exported from HEC-RAS and FLO-2D Other engineering flood studies 10

11 RiskMAP Deliverables Each RiskMAP Study will include flood depth grids for the 10, 50, 100, and 500 year flood frequencies All flood studies starting from 2009 onward will generate depth grids for any detailed study areas Level 1 HAZUS Analysis will also be completed in deliverable 11

15 How does HAZUS calculate damages for Earthquakes? Damage in HAZUS is described by five damage states: HAZUS uses damage states to estimate life-safety consequences of building damage, expected monetary losses due to building damage, expected monetary losses due to business disruption, and other social and economic impacts. 15

16 How does HAZUS calculate damages for Earthquakes? (Con t) Damage states and engineering calculations were used to develop fragility curves for each building type Fragility curves describes the probability of being in a specific damage state as a function of the size of an earthquake For structural damage a fragility curve expresses damage as a function of building displacement 16

The following data is required for each parcel: Building replacement value (typically use building improvement value). *Assessed values should not be used. Building square footage Building type (residential, commercial, industrial etc. ) Building count (per parcel) Can also update bridge, road, utility information Shake Maps are available at USGS Choose a geographic area> Click Archive Choose the appropriate network (Pacific NW)> Choose All Years> and choose Scenarios for Type Once a Shakemap is selected choose Downloads. Download the HAZUS Zip File and the Shape Files. 18
