One of the cornerstones of urban planning in many cities, zoning codes are sets of regulations used by local governments to control land use by defining what can and cannot be built in specific neighborhoods, what buildings can look like, and what uses can coexist in the same areas. Use-based zoning is an important tool for guiding development in most U.S. cities, but more recently, cities are turning to form-based codes, which focus on design rather than use. Local jurisdictions often push back when states attempt to preempt local control of zoning through statewide regulations that mandate higher density.

Lewis Mumford on the City 3: The City and Its Region
This short documentary film is the third part of a larger series hosted by Lewis Mumford, an American historian, sociologist, philosopher, and literary critic whose studies in the 20th century included attention to cities and architecture that influences the study and planning of cities into the present day. This film takes a broader view of cities, expanding to the regional level and warning about the ill effects of the sprawling forms that most U.S. cities took on during the mid-20th century, erasing pastoral landscapes and rural communities and undermining the benefits of cities.
