Opened in May 2009, it was developed on 250 hectares (620 acres) of what were the Neza I y II landfills, which in their 65 years of history received over 12,000 tonnes (13,000 short tons) of garbage from Mexico City.
[2] In the early decade of the 2000s, ideas were raised as to how to transform one of the largest landfills in the Americas into a center for shopping, ecology, education, and living, in the way that had already been accomplished in Santa Fe, Mexico City.
[4] Ciudad Jardín was opened by the State of Mexico governor (later Mexican president) Enrique Peña Nieto and by Slim on 22 May 2009.
[3] It is divided into two sections, 'Plaza Ciudad Jardín" and "Centro Comercial Ciudad Jardín", where two retail groups predominate: Wal-Mart with a Wal-Mart and Sams Club, restaurants Vips and El Portón and department store Suburbia; while Grupo Carso has Sears, Mixup and Sanborns.
The center is planned to be connected to route 3 of the Ferrocarril Suburbano de la Zona Metropolitana del Valle de México (suburban rail system) a line that should connect metro station Metro Nezahualcoyotl with Chalco.
