Stormwater ponds manage urban runoff and mitigate storm-event flooding. Stormwater ponds also offer various secondary advantages such as filtering pollutants, providing a habitat for wildlife, and adding recreational value and access to green spaces to communities. However, stormwater pond features and their potential to offer secondary benefits can vary based on the initial construction and the ongoing maintenance practices. This study developed an assessment tool for evaluating stormwater ponds' expected functioning for secondary benefits, including potential for pollutant filtering by shoreline vegetation, safety, and access by people for activities like walking or wildlife viewing. We used the tool to compare stormwater ponds in East Tampa and Riverview, Florida, communities with contrasting socioeconomic backgrounds. The overall pond functioning was consistent between both communities; however, several distinctions emerged between specific pond attributes. Suburban ponds exhibited narrower buffer zones, lower bank stability, and less lighting. Conversely, ponds in the lower-income East Tampa had lower accessibility due to a higher number of fences, more litter, and inferior water appearance. This study uncovered a need for consideration of stormwater pond secondary benefits in both communities and an untapped potential to transform stormwater ponds into vibrant green spaces.
Highlights• Stormwater ponds offer secondary ecological and social benefits, varying by initial construction and upkeep practices.• Differences in pond features were noted between inner-city and suburban communities, indicating areas for improvement. • There is potential to enhance stormwater ponds as green spaces in all communities, irrespective of socioeconomic status.
