Ramona Gardens Anti-Pollution Green Buffer

WSP USA implemented a nature-based solution for improving air quality at freeway-adjacent public housing in Los Angeles.

The Ramona Gardens Housing Development in central Los Angeles, home to 1,800 residents including 700 children, is one of the most polluted communities in California - area air quality is deemed unhealthy for 40 percent of the year.

A number of factors contribute to high levels of noise and air pollution, including its close proximity to major transportation corridors (freeways, toll roads and rail corridors), the urban heat island effect, local microclimate conditions and other socioeconomic factors. As a result, residents suffer disproportionately from serious health problems.

A natural park was proposed that would act as a buffer between the housing complex and the adjacent transportation corridors to improve air quality and provide other health benefits. After reviewing the site’s existing environmental conditions, health statistics and socioeconomic information, WSP monitored the area’s air quality data and meteorological conditions to determine the potential for air pollution reduction measures that could be integrated into the park.

The measures proposed include sound barriers, green buffers and other green infrastructure solutions using native plants and trees. This nature-based approach aims to improve not only air quality, but quality of life as well, creating a model for public housing developments and disadvantaged communities throughout California.
