2019 Map of Rio Grande City North

About this map

Rio Grande City and its dense network of colonias anchor this 2019 survey of Starr County, Texas. The landscape is defined by a distinct transition from the concentrated residential clusters of Los Olmos Colonia, Canales Colonia, and Live Oak Estates Colonia in the south toward the more open, ranching-oriented terrain to the north. These named colonias, including Trevinos Number 1 Colonia and Francisca Colonia, reflect the unique settlement patterns of the border region, where family-linked communities have developed along the tributaries of Los Olmos Creek.
