Urban green space and water features provide numerous social, environmental, and economic benefits, yet disparities often exist in their distribution and accessibility. This study examines the link between issues of environmental justice and urban water management to evaluate potential improvements in green space and surface water access through the revitalization of existing engineered water infrastructures, namely stormwater ponds. First, relative access to green space and water features were compared for residents of Tampa, Florida, and an inner-city community of Tampa (East Tampa). Although disparities were not found in overall accessibility between Tampa and East Tampa, inequalities were apparent when quality, diversity, and size of green spaces were considered. East Tampa residents had significantly less access to larger, more desirable spaces and water features. Second, this research explored approaches for improving accessibility to green space and natural water using three integrated stormwater management development scenarios. These scenarios highlighted the ability of enhanced water infrastructures to increase access equality at a variety of spatial scales. Ultimately, the "greening" of gray urban water infrastructures is advocated as a way to address environmental justice issues while also reconnecting residents with issues of urban water management.
城市绿地和水景提供了众多的社会、环境和经济效益,但它们的分布和可及性往往存在差异。本研究探讨了环境正义问题与城市水管理之间的联系,以评估通过振兴现有的工程水基础设施(即雨水池)来改善绿地和地表水可达性的潜力。首先,对佛罗里达州坦帕市和坦帕市(东坦帕)内城社区的居民进行了绿地和水设施相对可达性的比较。尽管在坦帕和东坦帕之间的整体可达性方面没有发现差异,但在考虑绿地的质量、多样性和大小时,不平等现象就显现出来了。东坦帕的居民获得更大、更理想的空间和水设施的机会明显较少。其次,本研究探讨了利用三种综合雨水管理开发情景来提高绿地和自然水可达性的方法。这些情景突出了增强型水基础设施在各种空间尺度上增加可达性平等的能力。最终,提倡将灰色城市水基础设施“绿化”作为解决环境正义问题的一种方式,同时也使居民重新关注城市水管理问题。
