2016 Map of Rio Grande City South

About this map

Rio Grande City and its surrounding colonias are situated along the sweeping northern banks of the Rio Grande in southern Starr County. This borderland landscape is characterized by a dense network of residential developments and rural colonias such as Las Lomas, Santa Rosa, and Valle Hermoso, which sit just north of the Lower Rio Grande Valley National Wildlife Refuge. The map details the transition from the city center to the surrounding agricultural and residential settlements, where Los Olmos Cr meets the river. Significant local landmarks include the Olmos Cem and several named subdivisions like Garza-Salinas II and B and E Colonia. The survey reveals a complex residential grid that has expanded away from the historic river crossing, following roads like 83 and E Main St through the scrublands of south Texas.
