HistoryA character grade: shown, never part of San Benito’s overall grade.
Few Texas towns list much on the Register (a typical Texas town has 0.0 per 10,000 residents, the U.S. 2.4), so San Benito’s 13.0 sits above most of its state (88% of Texas towns have fewer) while its 32 historic buildings outnumber those of 82% of U.S. towns.
How sure. Graded on any two of the three inputs instead, the letter would range from D to B. The pre-1940 share (±2.3 points) is firm at this size. The founding year is the first post office, not a stated founding date.

What stands out about San Benito’s past
Read from the archive, the National Register and the record. The page puts what stands out first.
San Benito is known as the "Resaca City". The Resaca de los Fresnos, 400 ft (120 m) wide, flows through the city. As indicated by its Spanish name, the resaca is a dry river bed. It is now the main canal of a large irrigation system.
San Benito was at first named "Diaz" in honor of Porfirio Díaz, president of Mexico at that time. The people in the San Benito area were predominantly of Mexican ancestry. The Anglo settlers came after the completion of the first irrigation system in 1906. Prior to that time, this region was an arid, mesquite- and cactus-covered wilderness. Irrigation water touched off crop production, supported by the railroad.
