Praia Grande is a municipality in the Baixada Santista Metropolitan Region, on the southern coast of the Brazilian state of São Paulo.

After its emancipation on 19 January 1967, the city slightly accelerated the pace of growth experienced since the 1950s, earning a higher quality in their public services, given the proximity of the municipal government with the reality of the local population.

However, this ease of access has brought great inconvenience, that they would be solved by 1993 when the city started a revolution: the transport system has been completely refurbished, more than 90% of the streets were paved, the sewage began an expansion of collection (which began with 60% of households by 2012 and reach 100%), being treated and thrown more than 3 km from the coast, the edge of the beach and the main tourist spots were completely re-urbanized, it was forbidden to input bus tours without prior authorization from the municipality, the road system has been completely revised and reconfigured on interventions that occurred until 2006.

Some projects are still to be deployed in the city, regardless of the administration, such as airport charges in the region of Andaraguá, State college campuses (UNESP) and Federal (UNIFESP), the transformation of municipal landfill in ecological park (awaiting decontamination of the soil) and Route 700, linking the Anhanguera to the Rodovia dos Imigrantes.

However, from the mid-1990s, the construction boom, which occurred through a series of infrastructure works, landscaping and urbanization, which until then were too poor, eventually attracting thousands of families in the municipality, search of jobs with contractors and builders, causing a huge swelling population in the region between the current South Expressway, the Rodovia Padre Manoel da Nóbrega and the Serra do Mar creating suburbs, as Quiet Garden, Ribeiropolis, Garden Fern, among others, but now, since all are in the process of urbanization with schools, kindergartens, public transport and flooring in most of its streets, as well as future investments made by the city size at these sites, such as 16 million dollars to be invested in the suburb Glory, in its complete redevelopment.

Today, Praia Grande is the city with the largest number of surveillance cameras in the Americas, and the second in the world, second only to London, United Kingdom.
