Final answer:
A city built atop a hill is most likely to exhibit radial organization, with roads and development emanating from a central elevated point. Urban planners use zoning and urban growth boundaries to manage sustainable urban growth and create efficient, livable environments.
Step-by-step explanation:
The city most likely to have a radial organization is b. A city built atop a hill. Radial cities typically have a central point with roads and development radiating outwards, and this pattern often emerges in hilltop cities due to their natural centrality and the need to connect the summit with the surrounding areas efficiently.
Urban planners use their expertise to design optimal building environments and transportation systems for new urban communities. They use concepts like zoning—which involves the regulation of the use and development of real estate—to ensure that urban growth is managed sustainably. This includes the implementation of urban growth boundaries to control the expansion of a city and preserve the environment, reduce infrastructure costs, and promote efficient urban density. Additionally, planning also involves creating master plans to direct future development in alignment with existing policies and the needs of the community.
Sustainable urban growth management entails a balance between community needs, environmental concerns, and economic drivers. Regulating development through zoning and planning allows urban areas to handle the pressures of growth while maintaining a high quality of life for residents and preserving natural resources.
