2.0 Project Narrative: 1. Introduction and Background ( 1.5 pages) 🔍 Defining the Problem Southern California’s industrial corridors—specifically Boyle Heights, Wilmington, and San Bernardino—are among the most heavily polluted and environmentally overburdened communities in the United States. These neighborhoods sit at the intersection of freeways, refineries, ports, railyards, and freight corridors, making them epicenters for cumulative air pollution from diesel exhaust, fine particulate matter (PM2.5), ozone (O₃), and volatile organic compounds (VOCs). • Boyle Heights (ZIP 90033) is surrounded by major freeways and railyards, with PM2.5 levels averaging 14.5 µg/m³, exceeding EPA thresholds. • Wilmington (ZIP 90744), adjacent to the Ports of Los Angeles and Long Beach, ranks in the 100th percentile statewide for diesel particulate matter and is surrounded by six oil refineries. • San Bernardino (ZIP 92410), home to the largest inland logistics hub in North America, regularly records ozone exceedance days over 100 per year, with sustained PM2.5 concentrations near 17.8 µg/m³. These pollution trends are persistent and intensifying due to expanding industrial development, lack of localized air monitoring, and inadequate regulatory enforcement. 🩺 Health Impact The long-term exposure to air pollution in these communities has led to widespread and disproportionate health burdens, especially among children, seniors, and people with preexisting conditions. • Asthma rates are 2–3 times higher than state averages. Pediatric emergency room visit rates for asthma reach 91.7 per 10,000 in Boyle Heights. • Cardiovascular diseases, including hypertension and stroke, are prevalent among elderly populations and are directly linked to chronic PM2.5 exposure. • Cancer clusters have been reported near refineries and railyards in Wilmington and San Bernardino, where lifetime cancer risk estimates from airborne toxics exceed 1,500 per million (epa nata). • Adverse birth outcomes (low birth weight, preterm birth) and developmental delays have been documented at above-average rates, especially near high-traffic corridors. The burden of illness is not only physical but also economic—impacting school attendance, workforce participation, and household income stability. ⚖️ Environmental Justice Concerns The environmental crisis in these areas is not evenly distributed—it is deeply tied to racial, economic, and geographic inequalities. • Over 85–95% of residents in each target area are Black, Latino, or Asian-Pacific Islander, and 30–40% live below the poverty line. • Many are renters in high-density zones near industrial facilities and have limited mobility, healthcare access, or language support. • These communities rank in the 95th–100th percentile in CalEnviroScreen 4.0 for cumulative environmental burden, yet receive disproportionately fewer public investments in clean air infrastructure, health mitigation, or legal enforcement. For decades, these areas have functioned as “sacrifice zones”, where infrastructure planning prioritized industry and transportation over public health and safety. As a result, BIPOC and low-income populations have been systematically overexposed to toxic air and underprotected by existing environmental policies. 📢 The Case for CleanAirNow CleanAirNow responds directly to this layered crisis by proposing a community-led solution to collect, visualize, and act on hyperlocal air quality data. By combining grassroots leadership with technical monitoring infrastructure, the project addresses not only environmental degradation but also the historical exclusion of frontline communities from environmental decision-making. This initiative aligns with the Justice40 Initiative, Executive Order 12898 on Environmental Justice, and state climate equity goals—ensuring that resources flow to the communities that need them most.
