GIS analysis of cumulative impact indicators in Los Angeles County: regulatory agency vs. community residents
For this project, I produced detailed maps showing the location of both air quality hazards and sensitive receptor facilities collected by government agencies and community residents located in seven different areas of Los Angeles: Boyle Heights, City of Commerce, Eagle Rock, Figueroa, City of Maywood, Pacoima, and Wilmington. The project?s hypothesis stated that there would be a discrepancy between the number of facilities provided by each collector making for an overwhelming amount of state coding problems. The California Air Resources Board developed land use policy guidelines that are designed to lower the cumulative health impacts by reducing air pollution exposure for new sensitive receptor facilities. This policy recommends minimum distances to separate sensitive receptor facilities from air quality hazards to minimize air pollution cumulative impacts. These guidelines currently relate to the citing of new sensitive receptor facilities however, the health impacts are the same for existing sensitive receptors within these threshold distance buffers. To accurately represent the location of both hazardous and sensitive receptor facilities, relevant facilities were defined and geocoded for mapping in ArcGIS, allowing for comparative analysis of information from regulatory agencies with community resident collected data. This allows for the discrepancies to be exposed so that a communal resolution to data compilation can be agreed upon. After research, it was found that this was correct however, the discrepancies were much larger than predicted.
