Shannon Van Zandt, Texas A & M University – “Poor and Minority Impacts from Hurricane Ike”

  1. 1. Poor and Minority Impacts from Hurricane Ike Shannon Van Zandt, Ph.D., AICP Research supported by a grant from the National Science Foundation (#0928926) entitled Developing A Living Laboratory for Examining Community Recovery and Resilience After Disaster and from a series of grants funded by NOAA, the TGLO and the CCC. The authors and not the NSF, NOAA, TGLO, or the CCC are responsible for the any findings and opinions expressed in this presentation or the paper upon which it is based. The full paper can be found in Housing Policy Debate, 22:1, 29-55
  2. 2. Objectives and outline • Introduce group to ―living laboratory‖ research from 2008’s Hurricane Ike on Galveston Island (TX) – My focus on social vulnerability factors, particularly as they relate to the spatial distribution of housing • Highlight related findings
  3. 3. Geography of Opportunity • Sprawl, concentrated poverty, and segregation have shaped metropolitan areas in ways that exacerbate existing economic and social inequalities • The geography of opportunity is based on two main premises: – where one lives is critical for taking advantage of available opportunities; – households have unequal abilities to live in places with good opportunities
  4. 4. Inequalities may be due to: • Discrimination in lending and real estate industries • A lack of, and a poor distribution of housing opportunities  Housing market segmentation  Uneven regional growth  Clustering of low-income housing Consequences include:  Poorer access to opportunity  Greater exposure to hazards
  5. 5. Housing inequalities determine the spatial pattern of Social Vulnerability (SV)

  8. 8. Hurricane Ike • Hurricane Ike (Galveston, TX 2008) provided an opportunity to validate SV mapping technique and examine impacts for socially vulnerable groups • Select study objectives – Did the spatial distribution of vulnerable populations mitigate or exacerbate damage and loss to property? – Do social vulnerability factors facilitate or impede decision-making with regard to dislocation and early repair/rebuilding decisions? – How do pre-existing physical and social development patterns alter the long-term recovery trajectories for socially vulnerable households and housing in physically and socially vulnerable neighborhoods?
  9. 9. Data and methods • Multiple data sources used: – Primary data: • Longitudinal panel survey of 1500 single family structures • Longitudinal panel survey of approximately 550 households – Secondary data sources • Galveston permit data • County appraisal district (CAD) parcel data • Analyses include: – Correlation analysis of impacts and actions taken by socially vulnerable groups – Spatial analysis relating development patterns to damage – Longitudinal analysis of housing recovery – Long-term displacement
  10. 10. In the urban core of Galveston, many lower quality homes are only elevated a foot or less off the ground, if at all. Here, a poorly-constructed home has slid off its foundation, and the other structural systems have also collapsed. FINDING: Inequitable development patterns affected damage received
  11. 11. In contrast, a West End vacation home sits well above the surge level, a block off the gulf coast, these high-quality homes received only wind damage, which as seen here, was quite minimal.

  18. 18. Summary • Disparate impacts to SV populations and their housing generate the potential for redevelopment and population change, including: – Loss of affordable housing stock – Exacerbation of pre-existing inequities • Highlights need for: – Targeting of resources – Capacity-building within SV populations – Pre-event planning for equitable recovery
