Final answer:
The question is about Faubourg Marigny, a neighborhood in New Orleans. It was intended to be a grand boulevard similar to Paris's Haussmann-led transformation but evolved differently into an area with cottages and other residential properties, unlike the uniform grandeur of Paris's thoroughfares.
Step-by-step explanation:
The excerpt provided references Faubourg Marigny, a historic neighborhood in New Orleans, which parallels the sweeping urban transformations undergone by the city of Paris in the 19th century. Much like the grand boulevards of Paris, envisioned by Baron Haussmann, Faubourg Marigny was intended to become a grand boulevard but instead developed into a less distinguished area filled with shopping centers, cottages, and other residential properties.
The transformation of Paris created a city with wide boulevards, structures with multi-class dwellings, and modern urban planning that incorporated clear roads, proper sewage systems, and gas lighting. However, Faubourg Marigny didn't fully realize this grand vision and ended up with a mix of residential buildings including Creole cottages that are characteristic of the region.
