A rapidly growing suburban city that remains essentially suburban in character even as it reaches populations exceeding 100,000 defines a specific type of urban landscape. These areas are characterized by decentralized business activity, extensive reliance on automobiles, and residential housing stock primarily consisting of single-family homes. Examples of such places can be found across the United States, particularly in the Sun Belt regions, such as Irvine, California or Plano, Texas.
The significance of these urban forms lies in their impact on regional economies, transportation patterns, and environmental sustainability. They often represent centers of job creation and economic growth outside of traditional urban cores. However, their reliance on car transportation can lead to increased traffic congestion and air pollution. Understanding their growth patterns is essential for addressing infrastructure needs and implementing sustainable development policies.
