Municipal parks with similar design features are found in cities and towns throughout the United States. As public commons, they reveal a great deal about social values, norms, and power. This study utilizes an environmental justice framework and a modified System for Observing Play and Recreation in Communities method to evaluate park conditions and usage. Forty-seven parks, most less than seven acres in size, located in census tracts reporting populations at or above the California averages for Asian, African American, or American Indian residents in the cities of Richmond, Berkeley, and Oakland, California were visited at various times throughout the day and week. Observations confirmed previous studies that found predominantly sedentary uses with limited variety. Among adult and teen park users, there were fewer women than men, which also corresponded with previous studies in other cities. Most parks had low levels of use considering the population density of the surrounding neighborhood. Access to sanitary infrastructure and drinking water was limited, as was equipment for adults. Facilities for competitive sports were common, while alternative outdoor facilities for group rhythmic, creative, or coordinated movement were rare. It is recommended that municipalities could address environmental inequalities and increase park usage and benefits for diverse female constituents by providing free or very low-cost culturally appropriate programming and equipment, enhancing sanitation infrastructure, and facilitating active transportation to/from parks.
