Data was sourced from LA County DPW illegal dumping reports for LA County unincorporated areas from 2015-17. Data includes location of illegal dumping site (by address) and days between the day the complaint was received and the date the waste was picked up. Data does not include complaints from other jurisdictions.

High Quality Transit Areas (HQTAs) are defined as being within 1/2-mile of fixed guideway transit and/ or bus rapid transit stations with service every 15 minutes or less during peak commute times. SCAG published two shapefiles of (HQTAs): one for actual HQTAs in 2012, and one for planned HQTAs in 2040.

Publicly accessible data on the size and location of all existing parks, recreational facilities, open space and natural areas was collected through collaboration between the Departments of Parks and Recreation with 86 cities to complete a countywide inventory of existing parks. A total of 3,023 parks were inventoried countywide.

Waste consolidation facilities within LA County
• The most recent report was obtained October 10, 2018 and the raw data was converted to excel.
• Limited dataset to facilities within LA County.
• Cleaned city names to reflect only those officially-designated cities or unincorporated areas within LA County.
• Added columns for full facility type.
• Generated tables representing number of facilities by city, countywide facilities by type, and the number of facilities by type by city.

• Raw data obtained as PDF. Programs categorized by Program Codes (the glossary is accessible here: https://www.calrecycle.ca.gov/lgcentral/paris/Codes).
• We used 2016 data because the 2017 data appeared incomplete. Converted PDF to a text file and used REGEX to clean the data.
• Generated chart indicating number and type of program by city.
• Please note that the figure in Excel is far more legible than that represented in this document, although the sheer volume of data presents significant challenges for visual representation

Raw data (2016) obtained as a PDF from CalRecycle. Data includes waste reduction and diversion programs categorized by Program Codes (https://www.calrecycle.ca.gov/lgcentral/paris/Codes) indicating number and type of program by city.

Groundwater contamination data was sourced from reports generated by the GeoTracker GAMA (Groundwater Ambient Monitoring & Assessment) database. Data includes concentrations and approximate locations of 39 historically-prevalent groundwater pollutants in public water system wells. Data includes the percent of wells with concentrations above maximum contaminant levels (MCLs) or comparison concentrations (health-based target values from other sources used where no Federal or State MCLs have been promulgated). Groundwater Basin Name, as well as Assembly and Senate district #s are also included.

Information on MCL or Comparison Concentration type is from the State Water Board website.

• Data was taken from the Los Angeles Countywide Parks & Recreation Needs Assessment initiated in 2015 and completed in 2016.
• Publicly accessible data on the size and location of all existing parks, recreational facilities, open space and natural areas was collected through collaboration between the Departments of Parks and Recreation with 86 cities to complete a countywide inventory of existing parks. A total of 3,023 parks were inventoried countywide.
• The four types of parks and open spaces used for the inventory were defined as follows:
1. parks (under 100 acres and contain active amenities),
2. regional recreational parks (over 100 acres and contain active amenities),
3. regional open space (over 5 acres and contain minimal amenities), and
4. natural areas (over 100 acres and no amenities)
• Local parks, recreational parks and regional open spaces (not natural areas) were then used to conduct a walkability analysis (detailed methods available) using LA County population data.
• The two data layers used included population locations (it excludes all areas where people are not living such as natural areas, industrial areas, etc.) and a layer that shows areas in LA County that are within half a mile of a park. These data layers were overlaid to show the areas that are beyond half a mile.
