| Abstract: |
This project is a grant from the National Fish and Wildlife Foundation to demonstrate the potential for community-based planning for the development of CSO controls in conjunction with large-scale community redevelopment projects. One of the challenges concerning the use of LID in urban areas is that citizens’ groups and property owners are often more concerned with the appearance of the neighborhood and economic development than with spending resources on water quality retrofits. Water quality planners must therefore balance the community’s goals with the expectations of developers, land use planners, and stakeholders concerning the integration of BMPs into the infrastructure. The Anacostia section of Washington, D.C. is the focus of a large-scale redevelopment effort. The project focuses on how LID controls can be integrated into the master plan for Anacostia, and how customized strategies and techniques can be developed to address the master plan vision of the project. The effectiveness of different approaches was modeled to determine the optimal combination(s) of LID landscape and building practices that can be incorporated into the plans in order to meet regulatory and water quality objectives. Different scenarios were explored, including water conservation and harvesting, green roofs, and other structural and non-structural controls. The Prince George’s County BMP Evaluation Module was used to demonstrate the effectiveness of the systems. Another focus of the project is on how to construct and maintain these systems to insure their long-term success. This includes private and public partnerships, overlay zones, financial incentives, and business improvement districts to maintain the long-term viability of the facilities. |
