Washington, DC (August 2010)- This report presents the common trends in how 12 local governments developed and implemented stormwater policies to support green infrastructure. The local policies examined in this paper include interagency cooperation, enforcement and management issues and integration with state and federal regulations.
This case study report describes a dozen cities and counties that are using green infrastructure approaches to reduce imperviousness and preserve natural open space throughout a watershed and at the neighborhood scale, as well as adding green infrastructure practices at the site level. These cases include success stories for building a comprehensive green infrastructure program, but they also provide insight into the barriers and failures experienced while trying to create a stormwater management system that includes more green infrastructure approaches.
Many communities are moving past the era of single objective spending and investing in runoff reduction and stormwater management strategies that have multiple environmental, economic, and social benefits. The greenest cities in terms of stormwater management use a wide range of policies and a number of approaches that focus on both public and private properties. This report originally focused on local stormwater regulations alone, but further investigation revealed that the real presence of green infrastructure in a community was due to many other programs and policies that can be adopted by a wide range of communities.
