A report in El Nacional alerts the authorities to the environmental threat posed by the lack of collective sewage treatment and facilities in the Poligono Central area of Santo Domingo. The city government of Santo Domingo has authorized mass construction of high-rise buildings in the area. The Poligono Central is the main financial, commercial and residential sector of Santo Domingo. Until the 1980s, the center was a residential area mainly consisting of single-family homes. It covers an area of five square kilometers from JF Kennedy to the north, 27 de Febrero Avenue to the south, Winston Churchill to the west and Ortega y Gasset Avenue to the east.
