The floods in the city of São Paulo, Brazil, are an historical trouble as a result of its urbanization process. The city has a total area of 1,521 km2, with 68% of urban area, where there are 1,000 km of underground streams, which represent 42% of the streams located in the urban area. Therefore, inundation problems are frequently observed due to runoff. The recurrence of floods makes government actions focused on flood control. The zoning of flood areas, associated to hydrological risk, is a technique to be used in the definition of patterns of land use and occupation, with the objective of minimizing the human and material losses resulting from the floods. This work indicates how the zoning of flooded areas can be articulated with the structural measures of flood control from the concept of the coexistence of the city with the urban waters.
