Single-use zoning, often referred to as Euclidean zoning, restricts specific geographic areas to a single land-use type, such as residential, commercial, or industrial development. By design, this practice separates these functions to avoid perceived incompatibilities, which inadvertently discourages the creation of walkable communities.1

Because homes are physically isolated from essential destinations like schools, workplaces, and retail stores, residents are forced to travel significant distances to meet their daily needs. This structural separation creates a heavy reliance on automobiles, as walking or cycling becomes impractical for most trips. Consequently, this dependence on personal vehicles contributes directly to urban sprawl, leading to longer commute times and increased traffic congestion on regional road networks.12
