Buildings erected on the spongy subsoil of downtown Mexico City will be limited to four stories under new construction and zoning regulations written as a result of the September, 1985, earthquakes, the government announced. Juan Gil Elizondo, director of urban reorganization and ecological protection, said the earthquake-prone city will be divided into three zones according to type of soil and seismic effects. The first section is the historic downtown. In the other two zones, the pace of construction and its concentration will be reduced by 20% to 50%.
