This rendering appears very conceptual as its a watercolor.
Therefore:
1.) not everything is worked out. Watercolor is great for conceptual renderings as it gives an IDEA of what it will be like (to help gather donations, publicize the project, etc.) but keep things abstract as there are probably few things that are well worked out, finalized, or even known (Parking, signage, etc.) - which leads to...
2.) the artist has to "fake in" some things to create to an environment that "feels" nice, vibrant, inviting, etc. rather than "empty". In my professional experience, much of this image is created as a "vision" and is not final. If I had to guess, the BAYLOR sign, the gold "stonge henge" things, and its relationship to the river (I would guess it will be raised, perhaps w/ dikes around/ in front) are all just "guesses" and represent items that will inevitably populate the area.
