Las Lomas, TX

Las Lomas is a census-designated place in Starr County's Rio Grande Valley, and its name points to the low hills of the surrounding terrain. The community's boundaries have shifted with nearby Rio Grande City: part of the Las Lomas CDP was annexed into the city before the 2010 census, so the local map is a mix of a distinct census place and a close relationship with the larger city. Starr County's early colonia-infrastructure work included Las Lomas, tying its history to the practical work of roads, drainage, utilities, and housing.

School lines run through Rio Grande City Grulla Independent School District, the Starr County district that serves the community. That connection matters because Las Lomas does not operate as its own municipality; people read it through the surrounding colonias, the school district, and the road toward Rio Grande City. The name, the rolling ground, and the city boundary are the clearest local clues: this is a Rio Grande Valley settlement whose story sits between countryside and city edge.
