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

Additional Hazards: Coastal Erosion

Overview: part of Texas coastline

Gulf of Mexico

Coastal Erosion

Zoom: Meters/Feet per year of erosion

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

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

Texas Geographic SocietyTRAINING PROGRAM

Instructor-led, Computer-based Trainingfor Hazard Mitigation & Emergency Managers ProfessionalsTraining 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

For more information or registration, please contact the Texas Geographic Society at: contactTXGS@texasgs.org 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.
