Texas Geographic Society Phase 2 of the Grant
1. Enhancing and expanding www.thmp.info• Adding information on other Hazards• Adding Population and Property Value vulnerability maps
2. Training• Providing THMP and HAZUS courses around the state.
3. Coordination and Outreach• Supporting key organizations• Working through related organizations• Building and Umbrella Group (HAMMER-TECH)
1. Enhancing and expanding www.thmp.info
A. Additional/Updated Hazards• Coastal Erosion• Dam Failure• Flood Risk Zones
B. Adding Asset Vulnerability• Population Vulnerability to Hazards• Property Value Vulnerability to Hazards
80 available Counties in THMP; 174 to go!
Additional/Updated Hazards: Flood Risk Zones: Completing statewide coverage
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]
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)
Hazard Risk ZoneExposure (ex. Population)
Population Vulnerability to Hurricanes
Overview: Corpus Christi area
Gulf ofMexico
Corpus Christi Bay
Population Vulnerability to Hurricanes
Several vulnerable areas; None-to-Low vulnerability in downtown area
Risk Zone 1
Risk Zone 2
Risk Zone 3
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
What is HAZUS-MH?
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)
HAZUS-MH is a planning tool that estimates damage and losses from natural hazards
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
Applications in Mitigation Planning & Emergency Management
HAZUS-MH
Response & Recovery
Loss Reduction
(Mitigation)
Emergency Preparedness
Emergency Preparedness
Develop emergency response plans
• Temporary housing
• Debris removal
• Emergency power and water
• Emergency medical services
• Evacuation/emergency route clearance
Organize response exercises
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
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
HAZUS-MH: Digital Elevation Model & Stream Generation
Ex. Travis County being prepared for Hydrologic and Hydraulic analysis
HAZUS-MH: Compute Hydrology & HydraulicsFlood area polygon (100-yr return) & Flood depth grid
for selected stream
This is our Study Case; same area identified in THMP
HAZUS-MH: AnalysisDamage Assessment: (ex. Residential Buildings)
Number of Residential Buildings in each Census Block (of Study Area) with 1 – 10% structural damage
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
HAZUS-MH: Analysis: ex. General Building Stock / Loss Estimate
Total economic loss can calculated for impacted area or single Census BlockThe previously identified Block totals 10,530,000 economic loss
• 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

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
For more information or registration, please contact the Texas Geographic Society at: [email protected] or 512-912-9695.
2005 Schedule
Texas GIS Forum (April)Texas Hurricane Conference (May)
…Stay tuned for many new training workshops held at hazard-related venues (June – Dec)
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.
