Sustainable micro drainage and its application in the transformation of garden neighborhoods

Abstract

The use of rain gardens and other nature-based solutions in contemporary projects indicate changes in the way cities are built in relation to the needs of adaptation to climate change. Within this theme, this article addresses the possibilities of applying sustainable drainage systems as microdrainage strategies and environmental qualification of consolidated urban fabrics, based on the study of garden neighborhoods in São Paulo. The methodology adopted includes the literature review, the urban study of a garden neighborhood, Vila Ipojuca, carried out from cartographic bases, aerial images and other official documents such as subdivision plans and drainage projects; field visits, and urban design exercises carried out with students in workshops. Preliminary results indicate that the application of sustainable microdrainage typologies, combined with traditional ones, contributes to greater technical and environmental efficiency of infrastructures and the urban environment quality.
