Camina tu Barrio was launched in 2017 as a community consultation in Coco del Mar, where we worked with residents to identify a series of needs aimed at improving life in the neighborhood—including improvements to the sidewalk system and the creation of a neighborhood park, the latter of which gave rise to the Coco Parque project. To delve deeper into the assessment of pedestrian mobility, we organized a “Jane Walk” with local residents—a collective walking tour that allowed us to identify critical points and opportunities for intervention on-site. The sidewalk project materialized in 2018 as a tactical urbanism initiative carried out in collaboration with the NGO Think Impact and 30 of its volunteers: in a single morning, we transformed a section of sidewalk usurped by informal parking into a tactical sidewalk built with gravel, plants, and tires, returning the space to pedestrians. The intervention proved its value as a proof of concept: three months later, the San Francisco Community Board built the permanent concrete sidewalk, replicating the logic of the original design. This project demonstrates how tactical urbanism, carried out with citizen participation and on a low budget, can catalyze permanent public investments and consolidate pedestrians’ right to urban space.
