29. Hazard Risk Zone B. Asset Vulnerability: Vulnerability = Exposure / Hazard Risk Zone Vulnerable areas are displayed and classified by census geography (Block or Census Tract) where Hazard Risk Zones intersect Exposed Assets (Population, Property Value) Exposure (ex. Population) THMP Data Layers: • Population Vulnerability (Total Pop, Total Pop Density) • Property Value Vulnerability (Total Property Value, Total Property Value Density) …for 5 Hazards [Hurricane, Floods, Tornadoes, Earthquakes, Subsidence]

33. Population Vulnerability to Floods vulnerable area! …may need further investigation

34. THMP to HAZUS • THMP Provides easy-to-use, online application (free) to: • Identify historical hazard occurrences • actual hazard event locations • summarized by county • Identify hazard risk areas • Determine relative vulnerability (to population and property value) • HAZUS Provides a complex, desktop application (at a cost?) to: • Quantify the impact of a specified hazard event • Perform damage assessment and loss estimation analysis …Study case may be identified in HAZUS, pre-determined by local experts and related information or by vulnerable areas previously determined in THMP

35. What is HAZUS-MH? HAZUS-MH is a planning tool that estimates damage and losses from natural hazards • It is a planning tool, NOT an engineering tool • Engineering-level data (i.e. Hydrology & Hydraulic studies for Flood modeling) can be input to increase accuracy, but results still produce planning-level estimations • It estimates physical damage & economic losses • It assesses population needs related to emergency management • It allows users to compare results from different study case scenarios, including those that result from specific mitigation actions (useful for benefits analysis)

36. HAZUS-MH: Technical Components • Software: Custom GIS (geographic information system) • Runs on ESRI products; ArcGIS and Spatial Analyst • ESRI products must be acquired separately • Spatial Analyst required for Flood Model only • HAZUS-MH is free from FEMA <www.fema.gov/hazus> • Current HAZUS-MH version (MR1) runs on ArcGIS 9.x • Previous HAZUS-MH version runs on ArcGIS 8.x • Data: National data sets • Inventory of assets (buildings, infrastructure, population/demographics, etc.) • Users may modify data sets or model factors • Users may add their own data

37. Applications in Mitigation Planning & Emergency Management Emergency Preparedness Response & Recovery HAZUS-MH Loss Reduction (Mitigation)

38. Emergency Preparedness • Develop emergency response plans • Temporary housing • Debris removal • Emergency power and water • Emergency medical services • Evacuation/emergency route clearance • Organize response exercises

39. Loss Reduction (Mitigation) • Mitigation Assessment • Identify ‘at-risk’ communities • Mitigation Measures • Strengthen existing structures • Strengthen window/door openings and siding • Mitigation Programs • Adopt and enforce hazard-resistant building codes • Land use planning

40. Response and Recovery • Post-disaster damage assessment and ground-truthing • Response planning for critical transportation outages • Identify critical infrastructure • Recovery action planning • Long-term economic recovery planning

41. HAZUS-MH: Digital Elevation Model & Stream Generation Ex. Travis County being prepared for Hydrologic and Hydraulic analysis

42. HAZUS-MH: Compute Hydrology & Hydraulics Flood area polygon (100-yr return) & Flood depth grid for selected stream This is our Study Case; same area identified in THMP

43. HAZUS-MH: Analysis Damage Assessment: (ex. Residential Buildings) Number of Residential Buildings in each Census Block (of Study Area) with 1 – 10% structural damage

44. HAZUS-MH: Damage Assessment: (ex. Residential Buildings) Mapped Although damage was light (1-10%) for most residential buildings, many were impacted – particularly in one Census Block. The previous THMP population vulnerability map indicated this potential

45. HAZUS-MH: Analysis: ex. General Building Stock / Loss Estimate Total economic loss can calculated for impacted area or single Census Block The previously identified Block totals 10,530,000 economic loss

46. HAZUS-MH: Other Notes • Results can be viewed & mapped many different ways • Including running mitigation scenarios to compare results • Inventory includes many different classifications of general building stock (by occupancy, by building type), essential facilities (several types), transportation systems (several types), demographics and more… • Local data and more sophisticated HAZUS techniques enhance the analysis

49. Texas Geographic Society TRAINING PROGRAM Instructor-led, Computer-based Training for Hazard Mitigation & Emergency Managers Professionals • Training Options: • THMP [www.thmp.info] • Texas Hazard Mitigation Package (THMP; pronounced “thump”) is an online mapping system from TXGS for displaying historical hazard occurrences, identifying relative risk areas and assessing vulnerabilities to population and property. THMP is also a geographic data distribution tool for other mapping/GIS systems. • Course is designed to introduce all people to an easy-to-use, free application • HAZUS • HAZUS-MH is a custom GIS planning tool from FEMA used for damage assessment and loss estimation from real or potential disasters Introductory and advanced courses focused on Flood and Hurricane modules (*ArcGIS required) • Intro to GIS [for THMP & HAZUS Users] • ArcGIS 9.0 is a geographic information system (GIS) from ESRI used for a multitude of applications, including • hazard mitigation and emergency response • Course is designed at an introductory level for THMP & HAZUS Users The Texas Geographic Society is pleased to announce a new Training Program aimed at professionals that need to more effectively mitigate, manage and respond to hazards using application-specific information and mapping technology. The courses are intended to be free or provided at a minimal cost. 2005 Schedule Texas GIS Forum (April) Texas Hurricane Conference (May) …Stay tuned for many new training workshops held at hazard-related venues (June – Dec) For more information or registration, please contact the Texas Geographic Society at: contactTXGS@texasgs.org or 512-912-9695.
