  1. Rebuilding a community Post hurricane Katrina By: Vernessa Shih Fall 2012 FINAL PRESENTATION PP M224A GIS Professor YohKawano

  2. What happened? • What were rebuilding goals? • What were parish priorities? • What areas saw the most success in rebuilding? • What areas need the most attention now? Hurricane Katrina Aug 23,2005 – Aug 31, 2005

  3. 140 mph

  4. Hurricane Katrina Route –Through Plaquemines, St. Bernard & St. Tammany Parish

  5. Let’s get factual . . . • 217,000 Homes Damaged • 1.4 million people displaced, 15 million people affected • estimated 75-110 billion dollar cost • (referred to as the costliest natural disaster in history) • extreme coastal erosion • Over 1,800 deaths

  6. WHAT IS MOST IMPORTANT TO YOU? (PICK THREE) Build better levees and other hurricane protection (58%) Encourage development of new housing (34%) Restore coastal areas (27%) Improve schools (26%) Attracting new businesses to the area (26%) Making reconstruction jobs available to residents (25%) Providing better community/social service (21%) Making street/highway improvements (13%) Reducing crime (13%) Devising a workable evacuation plan (13%)

  7. Jefferson Parish Build better levees and other hurricane protection Restore coastal areas Attract new businesses to the area Improve the school *107,000 damaged homes Orleans Parish Build better levees and other hurricane protection Encourage development of new housing Improve schools Make reconstruction jobs more available *largest number of displaced residents *90% evacuated Plaquemines Parish Build better levees and other hurricane protection Restore coastal areas Attract new businesses to the area Improve schools *over 50% buildings destroyed St. Tammany Parish Build better levees and other hurricane protection Restore coastal areas Attract new businesses to the area Make highway and street improvements *38,900 damage claims St. Bernard Parish Build better levees and other hurricane protection Restore coastal areas Buy out flood-prone properties Encourage development of new housing *29,000 destroyed homes

  8. Highlighting areas within and outside of a 5 mile service area to FEMA evacuation routes

  9. * Many FEMA applicants not included in this data were living in temporary FEMA trailers

  10. Hospitals and Schools in Louisiana and the 5 Parish Study Area

  11. *Highlighting areas of high African American population Indicators for Improvement: Calculating the decrease in students dropouts for 7-12th graders, comparing 2000 to 2010(from schools statistics tracked by Louisiana Department of Education

  12. Focus AREA: New Orleans Metropolitan Area

  13. Living below Poverty Line # of Vacant Housing Units Map Algebra to create a Priority NEED Index for Louisiana # of Unemployed Workers High School Dropout Rates

  14. Hurricane Katrina completely changed the way our country reacts to disasters

  15. Every Error Known to Man . . .

  16. Caveats and Addendums • Clearly it would have been beneficial to have access to additional data regarding the Hurricane, but when Katrina hit and then Rita, gathering data is most likely not at all a priority • Regardless of missing attributes, this is still an important area of study • Groundbreaking in terms of being able to see new applications of GIS for other disasters, using Google Earth/Twitter/Social Networking to track disasters, Hurricane Sandy Shapefiles are already available • Problems: • Many clearinghouses, databases, including FEMA have been closedor have severely limited access only allowed to organizations associated with rebuilding or giving grants • Disaster data is by nature very unreliable, due to the constant changes in population, displaced citizens addresses etc

  17.

  18. Skills Used • Point/line graduated symbol • Geoprocessing – Clipping • Geoprocessing – Joining • Geocoding KMZ/KML files • Custom Shape files • Original Data (built new shapefiles from addresses) • Aggregating attribute fields • Boundary sub-sets selections • Images • Model Building/Rasters • Pie Charts • HotSpot Analysis • Buffering/concentric buffers • Creating Need Index • Distance Analysis • Spatial Analysis

  19. Model Builder – Feature to Raster *Reclassified individual rastersusing ToolBox
