Haussmann's goal was to re-create and modernize Paris as it was in the Middle Ages. Economic status played a large role in the reorganization of Paris. Haussmann divided the city into districts according to economic status. With this division, came the need for a new water and sewer system. He created a system that kept wastewater and contaminated water separate so that the human waste could be used as fertilizer to the crops, thereby strengthening the economy. The division of districts separated each class of citizens, causing the bourgeoisie to flaunt their wealth- making the economy boom.
The renovation of Paris by Haussmann caused economic growth, which began when Haussmann replaced old streets and dilapidated houses with wide, tree-lined boulevards and beautiful, expansive gardens. The old streets in which stores were lined on discouraged shoppers because there were no sidewalks. With Haussmann's reconstruction of boulevards, consumers were encouraged to "stroll" the streets of Paris to purchase products. His strategic architecture of beautiful monuments, buildings, and homes, and the elegantly designed streets, kept rioters away and boosted the economy.
The reconstruction of Paris by Haussmann captured the beauty of Paris as it is today. Before his architectural influence, Paris was dilapidated, crowded, and unhealthy. With Haussmann's help, the city's economy flourished; the bourgeoisie was encouraged to shop the streets of Paris rather than traveling for their goods, and the lower class could now produce more goods to make money for themselves because of the water and sewer system.
