The 15-minute city model, which gained traction during the COVID-19 pandemic, focuses on ensuring that residents can access essential services and amenities within a 15-minute walk or bike ride from home. The vision is built on seven key principles: proximity, density, diversity, digitalization, human-scale design, flexibility, and connectivity. By prioritizing these elements, 15-minute cities can help reduce transportation costs, foster stronger community bonds through increased social interaction, and promote more sustainable, livable neighborhoods. From Paris to Portland, cities around the world are embracing this approach to encourage balanced, vibrant urban growth.
