    The world is becoming an urban space, increasing the distance between people and natural environment. Consequently, cities became a hard challenge to professionals who seek to solve urban environmental problems to improve the population's quality of life. To counter these adverse effects of urbanization and to promote an urban expansion more sustainable, ecological knowledge should be considered in urban planning. In this context appears green infrastructure, which consists of types of green spaces created for mimic urban landscape ecological and hydrological functions performed by natural environments. This study aimed to predict the expected effects on urban environmental quality, especially in the urban drainage system, due to different scenarios of green infrastructure adoption. For the seven proposed types of green infraestructure: green roof, cistern for rainwater reuse, permeable area (garden), ecological sidewalk, street tree, adoption of green public area and building certification, the permeable area is the parameter that most benefit the urban drainage, followed by the capture of rainwater. We expect infiltrated volumes in the order of millions of cubic meters. These volumes represent almost one meter less in the channel level at the worst scenario, reaching to 2.5 meters at excellent scenario. The green roofs have a significant effect on isolated points for flood mitigation, by reducing up to 10 cm the level of water inside channels at the best scenario. The ecological sidewalk has negligible effects on the drainage system, but it is crucial for the joint adoption with street trees, that offers numerous other benefits, as well as green public areas. The certification, as elsewhere in the world, is incipient but can support public policies to promote urban environmental quality. Certifications, street trees and the adoption of green areas are relevant to obtain more beneficial effects of urban environmental quality beyond those related exclusively to microdrainage.
