In addition, illegal housing became a major problem, as more houses are built in Mata Atlântica zones which, as well as being subject to preservation restrictions, are highly likely to suffer from mudslides. There are an estimated 11,045 houses built in "frozen" areas, that is, areas in which new houses are not allowed to be built. The number of new buildings in the region grows 20% every year. Another current threat to the city is the sea level rise, which may affect several beaches and buildings located close to the shore. In March 2012, the deputy mayor of São Sebastião, Wagner Teixeira (PV) was caught doing illegal fishing off the coast of the city, near Paredão Island, Alcatrezes Archipelago. He was on his private boat with five other men, and didn't stop until his engine ran out of gas, even with the coast guard on his tail with sirens on. He was carrying 116 kg of fish, including endangered species, and stated he wasn't aware of the prohibition of fishing in that area. The Port of São Sebastião will receive considerable investment in the next decade so that it increases its operation capacity in a long-term expansion project due to continue until 2035. The number of employees at the port is expected to jump from the current 450 to 4500, 2/3 of them being required to hire local residents. Another improvement expected for the next years (tentatively 2016) involves doubling the lanes of Tamoios Highway, which connects São José dos Campos and the neighboring city of Caraguatatuba and is the main route to the city for people coming from São Paulo and many other cities. Geography Virtually everything in the city is located on the narrow plains between the Atlantic Ocean and the mountains, except for some cell phone towers and transmission towers. In the central portion of the city, these plains are never wider than 3 km, although they may measure up to 6 km in the less developed areas to the west. Most of the city concentrates between the Enseada Beach (the last beach before Caraguatatuba) and the Guaecá Beach. From Toque Toque Grande beach to Boracéia Beach (the last beach before Bertioga), hotels, summer houses and nightclubs dominate the terrain. The Guaratuba River marks the border with Bertioga, while the Juqueriquerê River marks the border with Caraguatatuba. The city has an oceanic climate, with an annual average
