Identifying Vulnerable Schools in High Risk Environmental Justice Communities
Adam Dorr
Use pollution data to identify high-risk areas Use demographic data to identify vulnerable
environmental justice communities Identify most vulnerable schools for priority
intervention Geographic Area: Los Angeles County (by
census tract)
Midterm Goals
EPA National Air Toxics Assessment (NATA) 2002 data:◦ Cancer Risk◦ Neurological Risk◦ Respiratory Risk
Standardized Scales (0-1) Composite Index (0-1)
Sources and Methods
American Community Survey 5-Year Estimates 2005-2009 (US Census Bureau via Social Explorer)
Based on Massachusetts State Law and Atlanta City Code definitions of Environmental Justice Community:◦ 65% or more below median income (assumed: county)◦ 25% or more minority (assumed: ALL not “white alone”)◦ 25% or more foreign born◦ 25% or more under age 10 ◦ 25% or more age 65 or older
Community Vulnerability Scale (0-5)
Sources and Methods
ESRI/Microsoft:◦ California state boundary map◦ Los Angeles County census tracts boundary map◦ Shaded relief basemap◦ Major highways basemap
UCLA Mapshare:◦ Airports◦ Water bodies
Sources and Methods
Use pollution data to identify high-risk areas Use demographic data to identify vulnerable
environmental justice communities Identify most vulnerable schools for priority
intervention Buffer zones around EPA sites of concern Develop a predictive model:
◦ Risk Environmental Justice Community Test model in other cities
Final Project Goals
Inset map Point graduated symbol (schools) Aggregating attribute fields (scales and composite
scores) Creating Indices (EJ-Risk Combined Index) Geoprocessing (clipping, multiple layers) Buffering and dissolve (EPA sites of concern 0.5 mile
buffer) Attribute sub-sets selections (selected Los Angeles
County EPA sites of concern from nationwide dataset) Geocoding (EPA sites addresses)
