Reports from the California Integrated Water Quality System (CIWQS) sanitary sewer overflow (SSO) database were generated using the Interactive SSO Reports tool from the State Water Resources Control Board (SWRCB) Sanitary Sewer Overflow Reduction Program.
Data on Category 1, 2 and 3 SSOs in LA County for the years 2013 to 2017 was used.
The number and volume of spills was analyzed. For some spills, only a portion of the spill volume may have reached a waterbody.
Spills were categorized as small (10,000 gallons).

Poverty rate throughout LA County by race

The Gini Index is used as a measure of income inequality for years 2006-2017. The Gini Index is a ratio between 0 and 1. An index of 0 represents perfect income equality, while an index of 1 represents perfect inequality. The greater the number of the index, the greater income inequality exists.
The American Community Survey reports the Gini Index in Table B19083. We used data from the 5yr community survey for 2010-2017, 3yr community survey for 2007-2008, and the 1yr community survey for 2006. There was no data for the year 2005. Data for the following geographies was used: LA County, City of Los Angeles, California, U.S., San Diego County, and San Francisco County.
This data was used to graph the Gini Index over time for LA County from 2005-2017. We then compared LA County to City of Los Angeles, California, U.S., San Diego County, and San Francisco County from 2005-2017 in tabular and graphical format. Percent change for each geography from 2005-2017 was calculated and presented this in tabular form.

This data was taken from the Los Angeles County Economic Development Scorecards published by the LA County Chief Executive Office. The CEO did not provide underlying data; any missing data in this analysis was because it was not published or accessible through the Scorecard. The next Scorecard should be published by April 2019, and unreleased data was not provided for this analysis.
The Economic Scorecard reports on Los Angeles County programs that prioritize granting county business contracts to Local Small Business Enterprises (LSBEs), Disabled Veteran Business Enterprises (DVBEs), and Social Enterprises (SEs). These are defined and discussed on page 23-27 of the April 2018 Scorecard.
In 2016, the Board of Supervisors set goals of awarding twenty-five percent (25%) of the total value (referred to as utilization rate) of all contracts for goods and services to LSBEs and three percent (3%) to DVBEs by 2020. There is currently no goal for SEs.

** Water Use Type: MI=Municipal and Industrial; AG=Agricultural; SW=Seawater Barrier; and GW=Groundwater Replenishment

*** Water Use Grouping
Total MI Demand - Total consumptive demand or water used to meet municipal and industrial demands.
Potable Consumptive Demand (20x2020) - Demand used for calculating per capita water use for complying with SB x7-7 that excludes recycled water use. Recycled water is a part of water-use efficiency.
Total Demand - Total water use that includes municipal and industrial, agricultural, seawater barrier, and groundwater replenishment.
