GIS Valuable Tool in EM Identify risk Prepare for Identify vulnerability Respond to to that risk Recovery from Assess the extent of Mitigate (before, the risk during or after an Communicate the risk event) Better land use decisions
Response/Recovery - Damage Assessment
HAZUS (HAZards US – Multi-Hazard) Federal Emergency Management Agency (FEMA) disaster loss estimation and mitigation planning tool Geographic Information System (GIS) based Spatial Analysis tool required Expensive to purchase and to maintain the licenses Census Data Methodology for Floods, Hurricanes, and Earthquakes Physical damage Economic Loss Social Impacts
HAZUS - Flood Studies of discharge frequencies, including analysis of discharges from specific streams and the exposure to buildings and population from the resultant flooding. Allows users to evaluate the consequences of specific actions, such as the introduction of flow regulation devices, acquisition or elevation of flood-prone properties, and other mitigation measures.
Wisconsin HAZUS-MH Risk Assessment FFY 07 Pre-Disaster Mitigation Grant Coordination with Land Information and Computer Graphics Facility (LICGF) at UW – Madison and The Polis Center at Indiana University – Purdue University at Indianapolis (IUPUI) State wide riverine runs for all 72 counties and coastal runs for counties along Lake Superior and Lake Michigan Uses Digital Elevation Maps (DEM) DFIRMs where available Better the data, better the ending product Land Information & Computer Graphics Facility
Risk Assessment Cont’d Results were a 100-year flood analysis for each county Data estimates are derived from census data incorporated into HAZUS Total Building Estimated Total Total Damaged Total Economic Loss X Building Loss X General Occupancy Exposure X Buildings Buildings 1000 1000 1000 Agricultural 9 0 $222,488 $10,306 $2,506 Commercial 1,778 34 $6,950,225 $158,492 $38,671 Education 34 0 $757,459 $7,856 $1,665 Government 157 3 $470,664 $8,638 $932 Industrial 269 0 $2,024,873 $73,478 $19,549 Religious/Non-Profit 74 0 $627,954 $13,646 $1,851 Residential 117,741 551 $26,888,748 $188,061 $115,171 Total 120,062 588 $37,942,411 $460,477 $180,345
Mitigation Planning Statewide flood hazard risk assessment for State Hazard Mitigation Plan Flood analysis for each county Assist in the development of or updating the counties’ all hazard mitigation plans

GIS inRadiological Emergency Planning
GIS in Radiological EmergencyPreparedness Currently, only FEMA Region 5 has a GIS person devoted to Radiological Emergency Preparedness.
GIS in Radiological Emergency Preparedness Only in the last 3 years has Wisconsin Emergency Management considered GIS as part of the skill set for employees. 4 staff with GIS skills
Uses of GIS in Radiological Emergency Management Communicate Risk Develop Plans to mitigate risk Recovery – Post Event
Communicating Risk GIS can be a powerful tool in the process of conveying risk. Community Outreach Planning Zones Calendar
GIS in Risk Assessment and Planning Provide the public with maps that show: Areas that may be affected around the nuclear plant. Roads Evacuation Routes A calendar is sent to each resident within 10 miles of the nuclear power plant. State and County Plans Reception Centers Siren Locations Traffic Control Access Points
Use of GIS in Exercises To provide a visual aid in conveying technical data about a release. Exercise Use Only
Parcels Ingestion workshop Ingestion Planning Zone extends 50 miles from the nuclear plant. Discussions included using land parcels as a means to track individuals who did not evaluate.
Response and Recovery e x p e n INCIDENT d losses i t u r e s time Rapid local detection and response Short Recovery Time start of Intermediate detection and response Moderate Recovery Timeincident Slow detection and response Long Recovery Time
Areas Receiving Less Attention Recovery Why… There has not been an accident since Three Mile Island that has caused an evacuation. Lessons could be taken from other incidents that require recovery, such as flooding.
