Orange County 114 25-29 Regional AFH • In Westminster, there is very poor access to environmentally friendly neighborhoods for all residents, regardless of race/ethnicity. Map 11 – Environmental Health, is a series of maps showing data from the California Office of Environmental Health Hazard Assessment (OEHHA) California Communities Environmental Health Screening Tool (CalEnviroScreen 4.0). These maps were created by California HCD to facilitate fair housing planning, using CalEnviroScreen data from OEHHA14F 15. The CalEnviroScreen tool is designed to identify communities most affected by pollution, and those where residents may be especially vulnerable to its effects. To do this, it uses a composite score based on 13 different indicators of pollution burden – such as exposure indicators (e.g., diesel particulate matter levels and lead risk from housing and environmental effect indicators (e.g., location of solid waste facilities) - as well as eight indicators of population characteristics including sensitive population indicators (e.g., asthma rates) and socioeconomic factor factors (e.g., poverty and linguistic isolation). More detailed information on the mapping methodology is available on the OEHHA website15F 16. On these maps, green areas represent regions with more positive environmental factors, while red areas indicate regions with more negative environmental factors. These maps show the following relationship between an individual’s place of residence and their access to environmentally healthy neighborhoods: • Countywide, the areas with more positive environmental factors are along the coast, in the south, and northeast. The areas with more negative environmental factors are in the central parts of the County north of I-405 and west of the Costa Mesa Freeway (SR-55). • In the Orange County Urban County jurisdictions, most neighborhoods have primarily positive environmental factors. The areas with more negative environmental factors are located in the following places: o Stanton. o Southwest Placentia, next to Fullerton , which is an area of high POC segregation and is predominantly Hispanic. o San Juan Capistrano, in the Census Tract that encompasses the interchange between I-5 and the Ortega Highway (SR-74), which is a high POC segregation area and is predominantly Hispanic. • In Aliso Viejo, all neighborhoods in the city have positive environmental factors. 15 The maps were downloaded from the AFFH Data Viewer, which can be accessed at https://www.hcd.ca.gov/planning-and-community-development/affirmatively-furthering-fair-housing 16 https://oehha.ca.gov/calenviroscreen EXHIBIT 6
