The rivers and wetlands of our urban spaces on a global scale have been treated as our garbage dumps, sewage disposals, and industrial waste canals for far too long. As we filled and paved over our wetlands and watched as our rivers and estuaries turned foul and discolored, we turned our backs on these waterways for many years, not recognizing the enormous value these rivers and wetlands have for our physical and mental health and our connection to the non-human species and ecosystems around us. For the last couple of decades, we at Inter-Fluve have had the good fortune of working with visionary citizens, residents, business leaders, city managers, and others across the U.S. and internationally to design and oversee implementation of the recovery and repair of urban river and wetland ecosystems. From dam removal to river and wetland reconstruction and others, we have realized that the broad collaborations and community building that happens during these projects is what helps drive innovation, radical thinking, and new visions for our future. Among other projects discussed, we will highlight the recent and ongoing work on the Lower Don River in Toronto, a $1+ billion revitalization and redevelopment project in Canada's largest city.
