Looking at 8.8.9 of the Guide Spec, #5 bars are required for Lateral reinforcement for longitudinal bars #10 or larger. Given that the Guide Spec has requirements for the hoop spacing, why would they require a larger lateral reinforcement bars? We can meet the spacing requirement with a tighter spacing of #4 bars. This is for SDC A with SD1>1.0

Had a feeling you may have misplaced that decimal haha. I'm guessing it has something to do with what they mention in the Commentary for that section; in addition to providing shear strength, the hoops also serve to brace the longitudinal column steel.
