Environmental TCAC environmental health scores are determined by the Fair Housing Task Force based on 12 of the indicators that are used in the California Office of Environmental Health Hazard Assessment's (OEHHA) CalEnviroScreen 4.0 tool under the "exposures" and "environmental effect" subcomponents of the "pollution burden" domain. The CalEnviroScreen 4.0 tool considers (1) environmental factors such as pollutant exposure, groundwater threats, toxic sites, and hazardous materials exposure and (2) sensitive receptors, including seniors, children, persons with asthma, and low birth weight infants. Socioeconomic factors include educational attainment, linguistic isolation, poverty, and unemployment. Based on the environmental pollution and population indicators, the CalEnviroScreen ranks census tracts on a statewide level. A community or area that ranks in the 75th percentile statewide (25 percent worst) or above is considered a "disadvantaged community." Disadvantaged or "EX communities have been identified as communities that are disproportionately burdened by multiple sources of pollution. Regional Trends Asian or Pacific Islanders (non -Hispanic) residents countywide are most likely to experience adverse environmental health conditions, while White residents are the least likely. The central part of the county, in the areas generally around 1-5 have the lowest environmental TCAC scores (see Figure 45). The central Orange County cities of Santa Ana, Orange, and Anaheim all have concentrations of tracts with environmental scores in the lowest quartile. Tracts with the highest environmental scores are in western parts of the county (i.e., Cypress and west Anaheim), coastal cities (i.e., Seal Beach, Huntington Beach, and Newport Beach), and around the inland community of El Toro. CalEnviroScreen scores for the county generally follow a similar pattern to the TCAC scores, with the central Orange County cities having census tracts with greater environmental burdens than coastal areas (Figure 34). Local Trends TCAC environmental scores by tract in Santa Ana are shown in Figure 46 and Figure 47 as well as the location of Affordable sites and Mixed Income Sites respectively. Tracts in the central and western parts of the City received environmental scores in the second and third highest quartiles, while the tracts located along or in close proximity to the freeways (1-5, 1-405, and SR-55) that traverse the city, generally along the eastern and southern boundaries, received scores in the lowest quartile. No tracts in the city received an environmental score in the highest quartile. According to CalEnviroScreen, 26 census tracts in Santa Ana are disadvantaged communities, these tracts represent the 25% highest scoring census tracts in CalEnviroScreen 4.0. These tracts or Disadvantaged communities are located in the southeastern part of the city along an industrial corridor that parallels the SR-55, around the downtown area south of the 1-5, in the city's central core going westward to its boundary, and in the southwestern part of the city, which also has a large industrial land use base. The location of Disadvantaged census tracts closely follows the historic development pattern of the city, proximity to freeways, and adjacency to industrial uses. The oldest portions of the city, located in and around the downtown area, that were developed when planning and environmental laws were not what they are today, tend to suffer from a disproportionate burden of environmental pollution. For example, the Logan neighborhood, the City's earliest Mexican and Mexican - American neighborhood located northeast of downtown, is currently bounded by railroad tracks,
