4 RESULTS AND DISCUSSION
4.1 Urban Growth
The urban growth map produced using the aerial photographies and the SPOT PAN image can be visualized in Figure
3. According to that, the city studied had occupied completely the main plateau up to 1962. Actually, at that moment the
city did not have a law of zoning that could control or even guide its growth and, through some public decisions, the
city was been adapted to its industrial development dynamism.

The first law of zoning was elaborated in 1971 (law no. 1606/71) and its effect was not noted in 1973. As stated by that
law, the urban land use was organized and some directions of urban expansion were established.
Between 1962 and 1973 the city presented a new axe of growth, to the direction of South and Southeast zones, been
guided by the readiness of free space with infrastructure. During the period between 1973 and 1985, the urban growth
rate was more significant to the South zone. This was pulled by the law of zoning proposed in 1980, that specified that
area as unifamily residential zone.
The urban growth rate during this period was not the largest one but the most significant in terms of absolute numbers
(Table 1). At that time, the municipal district had an industrialization increase that produced effects to the urban area
like urban population and economical growth.
Between 1985 and 1997, it is possible to notice a decrease in the process (Table 1) caused by economical problems (80's
crisis) and for a larger vertical urban growth than horizontal one. The principal axes of urban growth during this period -
(Figure 3) toke place in the southwest zone of the city, where many illegal settlements appeared. The law of zoning,
approved in 1990, defined that area as "macro - zone of urban expansion", which associated to the low price of real
estate, motivated the growth to that direction. The last law of zoning, published in 1997, tried to correct those faults.
