Thanks to, Montirob, who shared the Frost Bank Headquarters HDRC link with us, I've gone hunting for more site plans for San Antonio.
Here is the site plan for the Thompson Hotel & Residences. It includes the elevations, and the good news is it's taller than we thought it was.
The building elevations start on page 76.

The heights are:
313 feet 8 inches to the top of the main roof parapet
305 feet 8 inches to the mechanical penthouse roof.
285 feet 8 inches to the main roof slab.
It also doesn't show it having 21 floors. It only shows 20 floors. The height of the 20th floor is 268 feet 4 inches.
The 20th floor is also where the setback is on the east side of the building. The setback on the west side of the building is just below 286 feet.
69 feet to the podium (5th floor).
It's also worth noting that these heights are measuring the building from the street level, but the building elevations also show the elevation as measured from the riverwalk level, which is an additional 12 feet lower. That means every height I just listed would be 12 feet higher when viewed/measured from the riverwalk level.
And, it's also worth mentioning that without counting the Tower of the Americas, this will be San Antonio's 8th tallest building. 314 feet is some decent height.
