Requa put a Moorish style Arch of the Future in the middle of the plaza with the arch spanning the Avenida de Palacios and the sides facing north and south. An upper deck housed flood lights and transmission facilities for an address system operated by Associated Oil Company. To further break up the plaza, Requa placed large low pools on the north and south sides of the arch. These pools reflected images of surrounding buildings. One pool contained an ornamental barge from which troubadours serenaded visitors. H. O. Davis had insisted arch and pool be put up to conceal fixtures and to enhance lighting. Requa considered them to be obstructions that did not belong in a Spanish-Baroque style plaza.
