 At that time the city was experiencing a considerable industrial expansion that increased its commercial and service sectors.From its very beginning, the city's original plan prohibited workers from living inside the urban area which was defined by Avenida do Contorno (a long avenue which goes around the city's central areas), reserved for government workers (hence the name of the trendy neighbourhood "Funcionários"), and bringing about an accelerated occupation outside the city's area well provided with infrastructure since its very beginning.Obviously, the city's original planners did not count on its ongoing population growth, which proved especially intense in the last 20 years of the 20th century.
