In 1928, a baseball field was laid out in that are to the west. In 1934, the Tempe Beach committee, headed by Garfield Goodwin , began construction of a cobblestone wall around the entire park and the development of the stadium bleachers. This use of cobblestones is unique and once extended to all of the park structure. With construction of a new swimming pool in the 1960s, much of this cobblestone work was lost. This terraced bleacher is built of river cobbles and has concrete benches faced with cobbles.
Low walls surrounding the stadium are of cobbles with concrete caps.
The front wall is divided into bays by cobble pilasters. The stadium bleachers face east, being constructed into the embankment of the former highway bridge approach. The Tempe Beach Committee of the Tempe Chamber of Commerce planned improvements for the park in the 1930s.
