Anchoring the northeast corner of Evans Park, the former Citizens State Bank is a two-story, three-bay building set back from the sidewalk line to make room for a row of Corinthian columns that identify the narrow building as a bank. Seen across the green expanse of the park, framed by ornamental date palm trees, the bank's portico gives the town square a welcome note of small-town architectural authority. The architects, Hull and Praeger, were from Victoria.

The two-story Duson Block at 2–8 N. Washington Street and the one- and two-story Hefner Building at number 100–112 line the east edge of Evans Park. Backing up to the Hefner Building is the two-story First National Bank Building (1966) at 200 E. Jackson Street by MacKie and Kamrath, who also de signed the similar El Campo City Hall (1968) at number 315, which occupies El Campo's original public square. On S. Washington Street facing Evans Park is the rice-processing and storage complex of the Texas–West Indies Company. East of that, at S. August and E. Monserrate streets, is the El Campo Rice Milling Company, the town's first rice mill, founded in 1903. Farther east at 402 E. Monserrate is the Rice Farmers Co-op.
