Joe King, the Brazoria County Judge, said in 2011 that he was not surprised that the postal agency targeted the post office for closure and that "[f]or years when I drove by, I wondered how many people it served. There's nothing there — just this tiny house about the size of my office, sitting in the yard of another house. There's nothing else out there."

The Columbia-Brazoria Independent School District operates schools in the area.
