The document discusses challenges and opportunities for cleaning up the Anacostia River from an economic development perspective. It notes that while billions have been spent on restoration, the river may still not be safe for fishing or swimming due to factors beyond local control. It also acknowledges that low impact development can be difficult on urban sites and green infrastructure does not provide the same monetary benefits as energy conservation. However, awareness of the river's condition is growing due to new development projects, and more developers see less tangible benefits to improved water quality.
