I found this about New York. (Scroll down to Visual Corridors.) The requirement is a certain number of visual corridors from inland streets to the water. Nothing I can find about preserving views of buildings... that would be restrictive in a place where real estate premiums are some of the highest in the world.

Austin's CVCs are mostly for areas not in downtown proper, though a few are. The majority cover land not south of the capitol, where downtown is located. Thus the most expensive parcels are not affected. So it would be tough to make the case for San Antonio using Austin as the example... mostly.
