During the colonial period, Iztapalapa was very rural, notable only as one of the primary providers of produce and flowers to Mexico City and its lake and canal transportation. Culhuacán had eighteen villages surrounding it in the pre Hispanic era, butby the 18th century, only San Lorenzo Tezonco and Santiago Acahualtepec remained. In the middle of the 18th century, there were still only 80 families in Iztapalapa, with 31 of them being Spanish. By the end of the same century, that would become 130 indigenous families distributed into nine barrios and three villages. At the end of the colonial period Iztapalapa would also include three haciendas and two ranches. During much of this time, Iztapalapa was also a stopover for travelers between Mexico City and Puebla or Veracruz. There were two main canals through here that connected the area with Chalco and Xochimilco. One of these was the Canal de la Viga, which was an important means of transporting corn, beans, vegetables and more into the capital These canals had control and customs checkpoints which divided Mexico City from rural areas. The most important of these was the La Viga control point due to the merchandise that passed through.
