Guidelines and spatial tests for the implementation of a green and blue system

Case study of the São Sebastião Stream

Abstract

The modification of water bodies during the urban growth process has promoted the impermeability of the soil and the disruption of natural systems, which favor the occurrence of flooding, inundations and overflow. The São Sebastião Stream is a water body in the municipality of Barretos, in the interior of São Paulo, which is partially open to the sky, but hidden due to the consolidated urban fabric that exists, which disregards its layout and its Permanent Preservation Area (APP), so that the transformation of its landscape through the requalification of its spaces and surrounding areas is essential. The objective of the article is to construct a methodology to propose guidelines and spatial essays for a balanced and resilient urban landscape, through the foundations of Nature-based Solutions, Green Infrastructure, ecological drainage tools, as predicated by Low Impact Development (LID) and urban afforestation. The proposal of guidelines and tests based on these foundations favors the implementation of a green and blue system, with devices that can be replicated in a systemic manner throughout the São Sebastião Stream sub-basin and with the possibility of crossing these limits to be allocated on the scale of the city of Barretos and in similar territories.
