The ongoing demolition of Via Perimetral in central Rio de Janeiro represents the city’s evolution towards an accessible waterfront and sustainable urban mobility. The reality, however, is that real estate speculation and preparations for the World Cup and Olympics have taken control of the city’s recent development with projects such as Porto Maravilha, leaving the majority of the city and state’s residents on the margins of progress. The opportunity for adaptive reuse of the very structure representative of Rio’s outdated infrastructure provides a chance to finally improve the quality of life of the region’s population and ecosystems, in the true spirit of FIFA and the IOC’s legacy policies. Utilizing 905 I-beams from the Perimetral’s structure, we propose to improve accessibility to basic services, urban centers, and safe livelihoods for people on the edges of local government’s conscience. The adoption of Risk Removal Strategies to resolve Erosion, Flooding, and Water Quality risks in precarious communities guides the development of the design of Passeio Rio Margens. Beginning with pilot programs along priority waterways such as the Irajá River in Cordovil, natural strategies and infrastructures like bioremediation and flood buffer zones are prioritized. Design Typologies incorporate the reused structural members into the project, providing visual and educational markers that denote critical ecological and infrastructural assets for the watershed’s future. Accessible routes are cut through these physical manifestations of our risk removal strategies. The typologies, when applied to specific locations in communities along the waterways of the Guanabara Bay Watershed, provide nodes in an evolving pedestrian and cycling mobility network that physically connects peripheral communities in the watershed to their ecological and urban centers. Passeio Rio Margens represents a new model of urban development, predicated on opportunity, resource management, and equality within a healthy, symbiotic urban ecosystem.
