The Brazilian cities' urbanization process was characterized by the lack of appropriate planning. It has been noted that the consequence of this phenomenon is a considerable growth of the soil sealing and the green areas reduction, especially at private spaces. However, the regularity instruments to use and occupy the soil introduce a new paradigm in their statement: sustainability. Although this context is legally presented, the systematic events involving floods at Maceió’s coastal plain, for example, suggests that this area’s urbanization – legally backed by those urban soil regularity instruments mentioned – had a significant impact on the natural hydrological cycle. The initial hypostasis is that the answer could be found though the analysis of the evolution of the private lots’ occupation. Thereby, this research’s goal is to evaluate the soil occupation legally backed by the urban soil regularity instruments at Maceió’s coastal plain in what concerns the pluvial water management. Aiming to do that, it is presented the following research steps: 1) Develop the theoretical background for urbanization, sustainable urban drainage and indicators; 2) Climate, environmental, social and legal characterization of the studied subject; 3) Analysis of the in lot occupation at the critical flooding areas in 2002 and 2017; 4) Data systemization. The analysis’ results confirmed that the urbanization occurred at the watershed’s critical flooding areas contributed to the growth of flooding events at the area. With that being said, it is recommended a revision of the urbanity parameters aiming to regulate a more efficient permeability rate and also green areas to enable the flow control at the source.
