Since 2013, the city hall of São Sebastião, on the north coast of São Paulo, has received at least four alerts about the risks of landslides and floods in the municipality, which were confirmed on February 18 and 19, when the city was reached by the greatest volume. of rainfall in the history of the country, with 680mm of precipitation in just 24 hours.
The first alert came in 2013, when a study by the State University of Campinas (Unicamp) on the expansion of risk areas used the municipality of São Sebastião as a target, detailing the risks of landslides in the region.
Five years later, in 2018, a survey by the Technological Research Institute (IPT) indicated 52 areas that were at risk of landslides. Among the regions pointed out by the organ, was São Sebastião.
In 2020, the São Paulo State Public Ministry, after studying the region, concluded that Vila do Sahy, the region most affected by the landslides and floods last weekend, would be “a true tragedy announced.”
Finally, in 2022, a proposal by the Housing and Urban Development Company of the State of São Paulo (CDHU), based on an analysis of the 2015 Mackenzie, suggests that families occupying Vila do Sahy be relocated to a neighboring area, where they would be away from the risk of landslides.
