Spring 2010 GIS in Emergency Mngt Spring 2010 GIS in Emergency Mngt Presentation Transcript

  • GIS in Emergency Management Roxanne Gray Bob BuschWisconsin Emergency Management June 3, 2010
  • 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
  • Project Monitoring and Compliance
  • 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.
