though the United States has a history and culture associated with using motorized vehicles as a means of commuting, policies and infrastructure can influence people's actions and habits. Post-COVID city The COVID-19 pandemic sparked proposals for radical change in the organization of cities. Barcelona was one city that proposed a radical change. The Manifesto for the Reorganisation of Barcelona was published after COVID-19. One hundred sixty academics and three hundred architects signed the manifesto. The manifesto proposed pedestrianization of the whole city, prioritizing bicycle transport and efficient public transportation. The concept of a living street was a vital part of the manifesto. Reduction of vehicle traffic during the pandemic positively impacted the environment as air and noise pollution significantly decreased. Residents put emphasis on the idea of a living street as it would introduce more nature into the city. Living streets in Barcelona create opportunities for children to have a safe environment to play. COVID-19 increased the desire for areas dedicated to urban green spaces, as these areas became places of refuge during the pandemic. The re-naturalization of the city is now held to a higher standard as it guarantees an increase in human health and wellbeing. Design The design of the living street aims to promote safe walking and cycling, emphasizing pedestrians. Living Streets are achieved by restricting car use and parking, diminishing convenience to motor vehicles. Decreasing vehicular traffic increases the appeal for Sustainable modes of transportation. This is accomplished through better infrastructure, traffic calming, integration of walking and cycling with public transport, policies that encourage mixed-use development, regulations that are sensitive to more vulnerable populations and commuters, and community traffic education. Proponents believe a successful design cannot simply be individual measures taken but a combined, comprehensive approach that implements all these factors into a fully integrated and incorporated design. Environmental Design Environmental design elements in a living street provide strategies to mitigate stormwater runoff and reduce the urban heat island effect. Green infrastructure such as roadside plantings, rain gardens, and other strategies have a growing importance as stormwater runoff is a fast-growing source of pollution. Impervious pavements repel stormwater, decreasing the amount of water that surfaces can absorb. Stormwater runoff absorbs any pollutants present on the surface. Contaminants such as road salt, fertilizers, oil, or chemicals from cars can dirty the runoff. Storm drains that lead directly into public waterways carries these pollutants, causing harm to the
