who?

Social vulnerability is determined by creating a standardized index from 0 to 1.00 for each variable, and then summing the total rating of all nine variables. The census tract with the sample SVI highest total score indicates the highest level of highest vulnerability. This project examines social vulnerability and physical hazards within the city of Culver City, California.

what?

Research is based on Dr. Susan L. Cutter’s “hazard-of-place” model of vulnerability, which examines the intersection between social conditions and biophysical elements at a specific place in time. Social conditions are measured using nine socio-demographic Sociovariables within five broad categories of 2012 ACS 5-year estimate data. All cities participating in the LACCDR project demographic use these five broad categories identified by the CDC. The variables author selected nine specific variables and collected data at the census tract scale. (Census block group data is preferred for finer grain analysis).

FEMA Flood Zone Classification Flood Zone A: 100 year flood, no base flood elevation or flood depth Flood Zone AO: 100 year shallow flood, 1-3 feet Flood Zone B: Area between 100-500 year flood
