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. While a strong motivation for these policies and programs is innovation in stormwater management, many communities are moving past the era of single objective spending and investing in runoff reduction and stormwater management strategies that have multiple benefits. Green infrastructure approaches have a range of benefits for the social, environmental and economic conditions of a community. Not only do these case studies include success stories for building a comprehensive green infrastructure program, but they also provide insight into the barriers and failures these communities experienced while trying to create a stormwater management system that includes more green infrastructure approaches.
