New Urbanism is an urban design movement that advocates for the creation of walkable, mixed-use communities with a focus on sustainability, diversity, and community engagement. It emphasizes the importance of designing cities and towns in a way that promotes social interaction, reduces reliance on cars, and fosters a sense of community among residents. New Urbanism seeks to create vibrant, livable spaces that reflect the needs and desires of the people who live there, rather than solely catering to the demands of automobiles and single-use zoning.
