What is the significance of the spine in the Griffin-Ford Latin American City Model?

• A. The spine concentrates commercial activity and housing for the elite, guiding outward growth from the CBD
• B. The spine is a major industrial belt along the river
• C. The spine is where disamenity zones are concentrated
• D. The spine represents a suburban ring of lower-density residential areas

Answer: (A)

The spine is a major corridor that concentrates commercial activity and elite housing, extending outward from the central business district. In the Griffin-Ford Latin American City Model, this spine acts as the artery through which wealth, services, and higher-end residential areas flow, shaping how the city expands along a defined axis rather than spreading evenly in all directions.

This corridor mirrors how modernization and economic power are organized in many Latin American cities: the spine gathers key amenities, offices, and upscale homes, drawing growth along its path and influencing surrounding neighborhoods. It’s not about an industrial belt along a river, nor about disamenity zones or a sprawling, low-density suburban ring. Those patterns appear in other parts of urban models, while the spine in this model specifically represents the concentrated, high-status axis that guides outward development from the CBD.
