The rainwater is a crucial element in the hydrologic cycle, however, due to human impacts in the environment, this cycle does not work as it should. Roads, highways, buildings, and other kinds of constructions are necessary in a community. These paved areas rely on build drainage systems to function properly, otherwise, the areas impact the waterway and consequently cause serious flooding, such as the ones near to Banco do Brasil, that is a recurring case of flooding’ over the last few years. In large cities, the lack of sustainable and green stormwater infrastructure is marked; That is why this study applies to the area of Plano Piloto - Brasília DF. The identification of these possible flooding areas was performed by analyzing the density and drainage order of the region, along with the calculation of the topographic factor (LS), belonging to the Universal Soil Loss Equation (USLE). Thus, this research aimed to locate the ideal areas for the implantation of rain gardens; A shallow depression to capture, temporarily pond, and absorb run-off water from impervious surfaces, for instance roofs and pavement, as Cityofames has shown (2016).
