Village de l'Est Temple

Refugee villagers from North Vietnam built a community that would be wildly successful at recovering after Hurricane Katrina. The communities success is a demonstration of the main limitation we experienced conducting this research project.

Neighborhoods are recognized as a core building-block of larger urban societies and recovery after disaster events depends heavily upon the strengths and weaknesses of the community rather than the individual. Understanding then the need for a neighborhood scale level of measurement, one can easily see the limitations presented by data no finer grained than zip code level.

Once you begin looking at urban indicators, such as different measures of density, it becomes apparent why smaller “neighborhood scaled” data becomes advantageous. Below are images from City-Data.com showing different populations densities by Census Tract for zip code 70129.
