Downloaded annual reports of HAP metal emissions from TRI Explorer for LA County.
Cleaned data and totaled masses of point source and fugitive air emissions for each of the pollutants for each year.
Generated line graphs showing the emitted masses per year for the HAP metals included in the TRI report list.
Three separate plots were required to show the changes in emitted masses over time since they range over four orders of magnitude.
Created heat maps of median household income and created proportional marker symbols for each emitter address location (2017).

All data used for this indicator were reported by Lila Higgins, Community Science Senior Manager for the LA County Natural History Museum (NHM).
Data on current ongoing programs were reported for January 1st, 2018 – November 15th, 2018.
Data on specific challenge projects were reported for all years they occurred (2016, 2017, 2018), but each project has a different timescale. The El Nino SnailBlitz was 3 months, but all other SnailBlitzes and RASCalsBlitz were only 2 months long. The City Nature Challenge was the shortest project lasting only 3-5 days.

Distributed generation capacity by city.

California Rapid Assessment Method (CRAM; an assessment method for monitoring the condition of wetlands) spatial data was sorted from the EcoAtlas and was then downloaded to ArcGIS where it was clipped to LA County and a color gradient depicting the CRAM scores was created for each point.
CRAM data was sorted to only include sites within LA County. These sites were then sorted by watershed and by land use and presented as a percentage of sites per score.

County-wide consumption:
Joined combined residential median usage (Btu) and residential median usage per square foot (Btu) data for 2016 to LA County shapefile. Compared values to 4 previous time periods: 2006, 2010, 2014, 2015.

City-level consumption: Obtained 2016 Energy Atlas data. Filled missing municipal-owned utility (MOU) data using California Energy Commission Energy Consumption Database. Used Energy Atlas square footage data for therms as a proxy for missing MOU square footage data associated with kWh consumption. Mapped values by city.
