What width range is typically associated with grand urban spaces?

The correct choice represents the typical width range of grand urban spaces, which is often between 80 to 450 feet. This range accommodates various design elements and functions associated with large public areas, such as plazas, boulevards, and urban parks.

Widths within this range enable the incorporation of features such as trees, seating areas, and pathways, while also providing sufficient space for gatherings and events. Wider spaces allow for a more open feel, essential in urban designs aimed at encouraging social interaction and movement. This flexibility in width is crucial for creating dynamic spaces that can serve multiple purposes within the urban environment.

In contrast, narrower widths may not provide the same level of versatility and aesthetic appeal desired in grand spaces, leading them to be less effective in fulfilling the goals of urban design. Thus, the 80 to 450 feet range is well-suited for the design of inspiring and functional urban spaces.
