2019 Map of La Blanca

About this map

Edinburg and its surrounding colonias anchor this landscape in the Rio Grande Valley, where a dense grid of irrigation infrastructure supports the region's agricultural character. Water management is central to the area's development, evidenced by the Santa Cruz Canal, Donna Drain, and the Engelman Gardens Reservoir in the northeast. This 2019 survey documents a complex pattern of residential clusters including San Carlos, La Blanca, and Doolittle, alongside numerous smaller settlements like Hern Colonia and Muniz Colonia. The road network, dominated by numbered mile roads such as E Mile 18 Rd and Mile 17 1/2 Rd, reflects a systematic division of land typical of South Texas. On the eastern edge, the city of Elsa appears, marking a transition toward further urban centers in Hidalgo County.
