Urban design involves arranging and designing buildings, public spaces, transportation systems, services, and amenities to shape urban areas. It blends architecture, landscape design, and city planning to create functional and attractive places. Urban design draws on placemaking, environmental stewardship, social equity, and economic viability to establish areas with distinct identities. It connects people and places, urban form and movement, and the built and natural environments. Principles of good urban infrastructure design include reducing costs and environmental impacts, integrating systems, conserving natural systems, and meeting community needs within walking distance.
