I can see a flow similar to this rendering of PCP's McKinney & Olive Building in Dallas. Imagining that the street in the foreground is Flores Street with Travis Street on the right, I can see how the landscaping, as well as some architectural elements, can continue towards the creek. Personally, I would flip this image horizontally; more oak trees could be saved with the parking garage on the Travis Street side. I just love those oak trees, I'd hate to see them go.
