The Black River Corridor: Visions for Restoration and Recreational Use ABSTRACT The goal of this project was to aid the City of Cape Town in creating a vision for park and recreational spaces throughout the Black River Corridor to ultimately improve the ecological and socioeconomic potential of the river. By documenting river conditions, talking to stakeholders, and researching river revitalization processes, we devel- oped visions for the area. A pathway route and potential economic op- portunities were recommended for an interdepartmental task force to continue with a multi-phase revitalization project. This project report is part of an ongoing research program by students and faculty of the WPI Cape Town Project Centre to explore and develop options for sustainable community development in South Africa.

To help assess the task of cleaning up and maintaining a polluted river, we also spoke with representatives from the Friends of the Liesbeek River. They emphasized how community awareness was a key component in restoring the Black River, and how that could be accomplished through a pathway.
