According to Diário do Transporte, the Santo André city government has mapped the properties covered by public utility declarations for the future Line 20-Rosa of the São Paulo Metro. The information is now available to the public in a new layer of the municipal geographic platform SIGA, at siga.santoandre.sp.gov.br.
What the map covers
The survey includes properties listed in two state resolutions issued by the Secretaria de Parcerias em Investimentos of the São Paulo State Government, SPI no. 96/2025 and no. 107/2026. Together, they cover about 50.8 thousand square meters in Santo André declared of public utility for expropriation, temporary occupation or easement.
The future line is planned to have four stations in the city: Afonsina, Príncipe de Gales, Portugal and Santo André. According to the report, the mapping was carried out by the city's urban planning team with support from the Metro team.
How to check a property
- Open the SIGA platform and click 'Visualizador de Mapas'.
- Click 'Temas Disponíveis', the first icon in the upper left corner.
- In the 'Pesquisar Camadas' field, select 'DUP – Declaração de Utilidade Pública'.
- Use the address or street search tool to find a specific area or property.
The consultation is free and can be done online. According to the city, the map is for information only and does not replace the state resolutions or other official acts on expropriation.
What a declaration means
According to Diário do Transporte, a public utility declaration does not mean that a property has already been expropriated. It also does not automatically prevent use, sale or new investment. Owners keep their rights, within legal and urban planning limits.
The report also notes that, under Federal Decree-Law 3,365/1941, necessary improvements are compensable, while useful improvements made after the declaration need the authorization of the expropriating authority to be compensated. Investments made without a careful risk assessment may therefore not be fully recovered if expropriation goes ahead.
