Urban planning is a field that deals with the development and design of cities, communities, and other built environments. It involves studying the physical, social, economic, and environmental aspects of urban areas to create plans for their growth and improvement. Urban planners work on various projects such as citywide master plans, zoning ordinances, transportation systems, parks and recreational facilities, housing developments, and community development initiatives. The goal is to ensure that cities are designed in a way that promotes sustainability, livability, and economic vitality while addressing the needs of their residents.
