The Olympics catalyst for Rio redevelopment writes in an article in March 18, 2014 –According to Rio’s Mayor’s Office, the port regeneration project consists of the “re-urbanization” of five million square meters, including the construction of four tunnels, 17km of cycle-ways, three sewage treatment facilities, and the refurbishment of 70km of sidewalks. But all of this development comes at a cost, and not just in terms of capital investment. The port region is the rightful birthplace of the city, and has always been densely populated. Some of the buildings that have fallen into disrepair through lack of investment from the city are the oldest and most beautiful in Rio, and also of extreme historical significance….[many of these are scheduled for demolition]….One of the most oft-cited complaints is the lack of room for affordable housing to be developed in the area; current residents would be moved on and their dwellings torn down. “The fact is that this is a central area, historically occupied by low income families,” explains Lilian Amaral de Sampaio, a local architect and urbanist. “Very little of the Porto Maravilha proposal was designated for social and lower-income housing or for residential developments in general” ⁽⁴⁹⁾.
