An increasingly prevalent trend in planning spheres is a shift towards “smart growth” as the standard. Smart growth is presented as a better way to build and maintain our towns and cities. Smart growth means building urban, suburban and rural communities with housing and transportation choices near jobs, shops and schools. This approach supports local economies and protects the environment . It means healthy communities where all citizens reap the benefits of stronger economies and access to improved community amenities. The benefits of smart growth, however, have not been felt by residents of West Oakland, California. Building housing near public transportation has been touted as a smart way to reduce air pollution in communities. In the California Bay Area, much of the mass transit infrastructure (such as the Bay Area Rapid Transit rail system) runs parallel to major freight corridors with heavy diesel traffic. Transit-oriented housing is being located around light rail stations and for the Bay Area, this means next to freeways and designated truck routes. One report notes that diesel truck and train traffic has been shown to reduce lung function in children, increase the risk of developing cancer and asthma, and affect school performance and sleep patterns – resulting in increased costs to the state for missed school days, missed work days, and health care costs . Current state legislation does not require regions to account for emissions from diesel trucks and trains, which may expose more residents to toxic air pollutants like diesel particulate matter. Environmental justice groups such as West Oakland Environmental Indicators Project (EIP) and the Ditching Dirty Diesel Collaborative have been working to change this.
